As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

6 PGCIL shall submit the complete action plan
He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC

Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra
(KoynaJaigadRGPPL) to control the power flow on EHV lines in Maharashtra MSETCL agreed to the above actions suggested by WRLDC
Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

5 Testing of frequency controller response of HVDC controllers of the
Chandrapur btb Gazuwaka btb and Talchar‐Kolar HVDC bipole links
6 PGCIL shall submit the complete action plan
He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC

2018 Hrs and 400 KV Parli(PG)-Pune(PG) ndash I was taken in service at 2151 Hrs
Effect Power flow on 400 KV Chakan-Lonikand and Pune(PG) ndash Kalwa
reversed load on Parli-Lonikand reduced Load on 220 KV Talegaon(PG)-
Talegaon(MS) SC increased to 280 MW
2 On dated 11th Nov 2013 at about 1040 Hrs FSC on 400 KV Raipur-Wardha
taken in sevice
Effect Flow on 400 KV Chandrapur-Warora ( SC quad line ) increased from
850 MW to 1128 MW flow on Chandrapur-II ndash Chandrapur-I ( SC twin moose
line ) increased from 360 MW to 685 MW Flow on 400 KV Raipur-Wardha DC
increased from 950 MW to 1450 MW APML generation reduced from 1950
MW to 1650 MW Maharashtra over drawl increased by 300 MW
Any switching operation in CTU network connected to Maharashtra system has major
impact on power flow and many times loading on lines become critical Only after
enquiry with WRLDC control room by SLDC Kalwa switching events are informed It is
informed that FSC was taken in service to improve voltages in South Maharashtra
please note that 400 KV Solapur-Kolhapur-I Kolhapur-Mhapusa-II RGPPL-
Nagothane-I amp RGPPL-Newkoyna-II lines were out of service in south Maharashtra
Voltage profile could have been improved by taking these lines in service
In integrated system any switching event in CTU network has impact on entire state
network and required to be carried out in coordination with state SLDC
Member Secretary WRPC stated that Item no 92 amp 910 are related to communication gap between SLDC MSETCL amp WRLDC with other He requested WRLDC amp SLDC Maharashtra to harmonize datainformation

OTHER ITEMS FROM POWER GRID
SA-1 MOU for Tapping of Auxiliary Power supply from tertiary of 40022033 kV Transformer in POWERGRID sub-station
The ICTs in various POWERGRID substations having 33 kV Bushings which are
connected to AC Distribution Board through 33 kV440 V Transformers The Power
supply through this Transformer is tapped whenever the requirement arises
Generally the back up supply in event of the Auxiliary supply is provided through
DG Set In case of failure of DG Set power is taken from 33 kv of ICT
In this context it is to intimate that the 765 kV Station at Solapur is under construction
and likely to be commissioned by December end The station will have the line
coming from Raichur in Southern Region This will connect POWERGRID
SOUTHERN REGION and WESTERN REGION directly and the entire power system
of India will have one frequency
Further the Solapur sub-station would be the most important station and the failure of
AC power supply to the sub-station will affect the reliability of the station
The MOU for tapping of power through 33 kV side of the Transformer needs to be
addressed by local MSETCL and MSDCL offices
SLDC MSETCL assured to look in to the matter amp advised the PGCIL to consult with local Discom to short out the issue
SA-2 Dismantling of Shunt Reactor at Aurangabad sub-station
The clearances for shifting of Shunt Reactor from MSETCL Aurangabad sub-station to
POWERGRID Aurangabad sub-station was approved in earlier OCCM and
accordingly the Committee has agreed to dismantle the Reactor in Akola-Aurangabad
line I which is in operation without Reactor from last two months
Minutes of 453rd OCC meeting held on 15th November 2013
PGCIL WRTS-I representative intimated that after repeated requests MSETCL
Aurangabad is not allowing the dismantling of Reactor
SLDC MSETCL assured that the matter to take up with Aurangabad MSETCL SS to resolve above issue on urgent basis

Annexure‐94
Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II

As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra
(KoynaJaigadRGPPL) to control the power flow on EHV lines in Maharashtra MSETCL agreed to the above actions suggested by WRLDC
Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

Member Secretary WRPC intimated that Member GOampD had submitted action plan
to MOP regarding the synchronization of SR with NEW grid Following salient
aspects are covered in action plan
1 Implementation of recommendation of protection audit of under frequency
load shedding relays settings as per National Power Committee
2 Installation of Special Energy Meters and PMUs at Solapur and Raichur ends
Minutes of 453rd OCC meeting held on 15th November 2013

4 Review of SPS for Talcher‐Kolar HVDC bipole
5 Testing of frequency controller response of HVDC controllers of the
Chandrapur btb Gazuwaka btb and Talchar‐Kolar HVDC bipole links
6 PGCIL shall submit the complete action plan
He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC

OTHER ITEMS FROM POWER GRID
SA-1 MOU for Tapping of Auxiliary Power supply from tertiary of 40022033 kV Transformer in POWERGRID sub-station
The ICTs in various POWERGRID substations having 33 kV Bushings which are
connected to AC Distribution Board through 33 kV440 V Transformers The Power
supply through this Transformer is tapped whenever the requirement arises
Generally the back up supply in event of the Auxiliary supply is provided through
DG Set In case of failure of DG Set power is taken from 33 kv of ICT
In this context it is to intimate that the 765 kV Station at Solapur is under construction
and likely to be commissioned by December end The station will have the line
coming from Raichur in Southern Region This will connect POWERGRID
SOUTHERN REGION and WESTERN REGION directly and the entire power system
of India will have one frequency
Further the Solapur sub-station would be the most important station and the failure of
AC power supply to the sub-station will affect the reliability of the station
The MOU for tapping of power through 33 kV side of the Transformer needs to be
addressed by local MSETCL and MSDCL offices
SLDC MSETCL assured to look in to the matter amp advised the PGCIL to consult with local Discom to short out the issue
SA-2 Dismantling of Shunt Reactor at Aurangabad sub-station
The clearances for shifting of Shunt Reactor from MSETCL Aurangabad sub-station to
POWERGRID Aurangabad sub-station was approved in earlier OCCM and
accordingly the Committee has agreed to dismantle the Reactor in Akola-Aurangabad
line I which is in operation without Reactor from last two months
Minutes of 453rd OCC meeting held on 15th November 2013
PGCIL WRTS-I representative intimated that after repeated requests MSETCL
Aurangabad is not allowing the dismantling of Reactor
SLDC MSETCL assured that the matter to take up with Aurangabad MSETCL SS to resolve above issue on urgent basis
SA-3 TESTING OF FREQUENCY CONTROLLER IN HVDC BACK TO BACK STATION AT
BHADRAWATI
WRTS-I PGCIL intimated that as per the guidelines circulated by CEA on 30092013
the Frequency Controller in all the HVDC stations including Back to Back are to be
tested to facilitate the smooth synchronization of 765 kV Raichur-Solapur line The
preparation for charging of Raichur ndashSolapur line is in full swing and the line is likely to
be commissioned by December 2013 end
PGCIL further intimated that as per the procedure received from the CEA the power flow through HVDC Bhadrawati needs to be controlled between 500 to 600 MW and the frequency range shall be 495 HZ to 505 HzThe testing is to be carried out at the earliest so that the necessary feed back is to be given to CEA well before the charging of 765 kV Raichur-Solapur line
Member Secretary WRPC stated that a separate meeting would be held on 19112013 wherein the detailed procedure of frequency controller testing will be discussed thoroughly and testing will be carried out by involving SRPC amp SRLDC on suitable date
Subsequently a meeting was held on 19112013 at WRLDC Mumbai wherein procedure for the testing of frequency controller at HVDC BTB at Bhadravati was agreed upon The detailed procedure for the testing of frequency controller at HVDC BTB at Bhadravati on 22112013 is enclosed at Annexure-SA3 WRTS-I PGCIL intimated that the test was successfully conducted on 22112013(report attached at Annexure-SA31)

Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra
(KoynaJaigadRGPPL) to control the power flow on EHV lines in Maharashtra MSETCL agreed to the above actions suggested by WRLDC
Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

5 Testing of frequency controller response of HVDC controllers of the
Chandrapur btb Gazuwaka btb and Talchar‐Kolar HVDC bipole links
6 PGCIL shall submit the complete action plan
He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC

reversed load on Parli-Lonikand reduced Load on 220 KV Talegaon(PG)-
Talegaon(MS) SC increased to 280 MW
2 On dated 11th Nov 2013 at about 1040 Hrs FSC on 400 KV Raipur-Wardha
taken in sevice
Effect Flow on 400 KV Chandrapur-Warora ( SC quad line ) increased from
850 MW to 1128 MW flow on Chandrapur-II ndash Chandrapur-I ( SC twin moose
line ) increased from 360 MW to 685 MW Flow on 400 KV Raipur-Wardha DC
increased from 950 MW to 1450 MW APML generation reduced from 1950
MW to 1650 MW Maharashtra over drawl increased by 300 MW
Any switching operation in CTU network connected to Maharashtra system has major
impact on power flow and many times loading on lines become critical Only after
enquiry with WRLDC control room by SLDC Kalwa switching events are informed It is
informed that FSC was taken in service to improve voltages in South Maharashtra

OTHER ITEMS FROM POWER GRID
SA-1 MOU for Tapping of Auxiliary Power supply from tertiary of 40022033 kV Transformer in POWERGRID sub-station
The ICTs in various POWERGRID substations having 33 kV Bushings which are
connected to AC Distribution Board through 33 kV440 V Transformers The Power
supply through this Transformer is tapped whenever the requirement arises
Generally the back up supply in event of the Auxiliary supply is provided through
DG Set In case of failure of DG Set power is taken from 33 kv of ICT
In this context it is to intimate that the 765 kV Station at Solapur is under construction
and likely to be commissioned by December end The station will have the line
coming from Raichur in Southern Region This will connect POWERGRID
SOUTHERN REGION and WESTERN REGION directly and the entire power system
of India will have one frequency
Further the Solapur sub-station would be the most important station and the failure of
AC power supply to the sub-station will affect the reliability of the station
The MOU for tapping of power through 33 kV side of the Transformer needs to be
addressed by local MSETCL and MSDCL offices
SLDC MSETCL assured to look in to the matter amp advised the PGCIL to consult with local Discom to short out the issue
SA-2 Dismantling of Shunt Reactor at Aurangabad sub-station
The clearances for shifting of Shunt Reactor from MSETCL Aurangabad sub-station to
POWERGRID Aurangabad sub-station was approved in earlier OCCM and
accordingly the Committee has agreed to dismantle the Reactor in Akola-Aurangabad
line I which is in operation without Reactor from last two months
Minutes of 453rd OCC meeting held on 15th November 2013
PGCIL WRTS-I representative intimated that after repeated requests MSETCL
Aurangabad is not allowing the dismantling of Reactor
SLDC MSETCL assured that the matter to take up with Aurangabad MSETCL SS to resolve above issue on urgent basis
SA-3 TESTING OF FREQUENCY CONTROLLER IN HVDC BACK TO BACK STATION AT
BHADRAWATI

Annexure‐94
Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II

As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra
(KoynaJaigadRGPPL) to control the power flow on EHV lines in Maharashtra MSETCL agreed to the above actions suggested by WRLDC
Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

Member Secretary WRPC intimated that Member GOampD had submitted action plan
to MOP regarding the synchronization of SR with NEW grid Following salient
aspects are covered in action plan
1 Implementation of recommendation of protection audit of under frequency
load shedding relays settings as per National Power Committee
2 Installation of Special Energy Meters and PMUs at Solapur and Raichur ends
Minutes of 453rd OCC meeting held on 15th November 2013
3 Design and implementation of SPS for Solapur‐Raichur 765 kV lines
4 Review of SPS for Talcher‐Kolar HVDC bipole
5 Testing of frequency controller response of HVDC controllers of the
Chandrapur btb Gazuwaka btb and Talchar‐Kolar HVDC bipole links
6 PGCIL shall submit the complete action plan
He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC

Talegaon(MS) SC increased to 280 MW
2 On dated 11th Nov 2013 at about 1040 Hrs FSC on 400 KV Raipur-Wardha
taken in sevice
Effect Flow on 400 KV Chandrapur-Warora ( SC quad line ) increased from
850 MW to 1128 MW flow on Chandrapur-II ndash Chandrapur-I ( SC twin moose
line ) increased from 360 MW to 685 MW Flow on 400 KV Raipur-Wardha DC
increased from 950 MW to 1450 MW APML generation reduced from 1950
MW to 1650 MW Maharashtra over drawl increased by 300 MW
Any switching operation in CTU network connected to Maharashtra system has major
impact on power flow and many times loading on lines become critical Only after
enquiry with WRLDC control room by SLDC Kalwa switching events are informed It is
informed that FSC was taken in service to improve voltages in South Maharashtra
please note that 400 KV Solapur-Kolhapur-I Kolhapur-Mhapusa-II RGPPL-
Nagothane-I amp RGPPL-Newkoyna-II lines were out of service in south Maharashtra
Voltage profile could have been improved by taking these lines in service
In integrated system any switching event in CTU network has impact on entire state
network and required to be carried out in coordination with state SLDC

OTHER ITEMS FROM POWER GRID
SA-1 MOU for Tapping of Auxiliary Power supply from tertiary of 40022033 kV Transformer in POWERGRID sub-station
The ICTs in various POWERGRID substations having 33 kV Bushings which are
connected to AC Distribution Board through 33 kV440 V Transformers The Power
supply through this Transformer is tapped whenever the requirement arises
Generally the back up supply in event of the Auxiliary supply is provided through
DG Set In case of failure of DG Set power is taken from 33 kv of ICT
In this context it is to intimate that the 765 kV Station at Solapur is under construction
and likely to be commissioned by December end The station will have the line
coming from Raichur in Southern Region This will connect POWERGRID
SOUTHERN REGION and WESTERN REGION directly and the entire power system
of India will have one frequency
Further the Solapur sub-station would be the most important station and the failure of
AC power supply to the sub-station will affect the reliability of the station
The MOU for tapping of power through 33 kV side of the Transformer needs to be
addressed by local MSETCL and MSDCL offices
SLDC MSETCL assured to look in to the matter amp advised the PGCIL to consult with local Discom to short out the issue
SA-2 Dismantling of Shunt Reactor at Aurangabad sub-station
The clearances for shifting of Shunt Reactor from MSETCL Aurangabad sub-station to
POWERGRID Aurangabad sub-station was approved in earlier OCCM and

Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

OCC Approved Outage Statistics for Oct 2013
Approved Availed age
As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra
(KoynaJaigadRGPPL) to control the power flow on EHV lines in Maharashtra MSETCL agreed to the above actions suggested by WRLDC
Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that

Annexure‐94
Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra
(KoynaJaigadRGPPL) to control the power flow on EHV lines in Maharashtra MSETCL agreed to the above actions suggested by WRLDC
Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

5 Testing of frequency controller response of HVDC controllers of the
Chandrapur btb Gazuwaka btb and Talchar‐Kolar HVDC bipole links
6 PGCIL shall submit the complete action plan
He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC

OTHER ITEMS FROM POWER GRID
SA-1 MOU for Tapping of Auxiliary Power supply from tertiary of 40022033 kV Transformer in POWERGRID sub-station
The ICTs in various POWERGRID substations having 33 kV Bushings which are
connected to AC Distribution Board through 33 kV440 V Transformers The Power
supply through this Transformer is tapped whenever the requirement arises
Generally the back up supply in event of the Auxiliary supply is provided through
DG Set In case of failure of DG Set power is taken from 33 kv of ICT
In this context it is to intimate that the 765 kV Station at Solapur is under construction
and likely to be commissioned by December end The station will have the line
coming from Raichur in Southern Region This will connect POWERGRID
SOUTHERN REGION and WESTERN REGION directly and the entire power system
of India will have one frequency
Further the Solapur sub-station would be the most important station and the failure of
AC power supply to the sub-station will affect the reliability of the station
The MOU for tapping of power through 33 kV side of the Transformer needs to be
addressed by local MSETCL and MSDCL offices
SLDC MSETCL assured to look in to the matter amp advised the PGCIL to consult with local Discom to short out the issue
SA-2 Dismantling of Shunt Reactor at Aurangabad sub-station
The clearances for shifting of Shunt Reactor from MSETCL Aurangabad sub-station to
POWERGRID Aurangabad sub-station was approved in earlier OCCM and
accordingly the Committee has agreed to dismantle the Reactor in Akola-Aurangabad
line I which is in operation without Reactor from last two months
Minutes of 453rd OCC meeting held on 15th November 2013

Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC

Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra

Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

Chandrapur btb Gazuwaka btb and Talchar‐Kolar HVDC bipole links
6 PGCIL shall submit the complete action plan
He opined that local generation should be identified for tripping of units under SPS ie
for Talcher ndash Kolar HVDC the generations in ER should be identified
WRLDC proposed that the KSK amp JPL generation back down shall be chosen for SPS
at Solapur‐Raichur 765 kV lines as their station have PPArsquos with SR constituents
Member Secretary WRPC stated that KSK and JPL representatives are not present
therefore SPS for Solapur‐Raichur 765 kV lines would be designed after consent
received from KSK and JPL Also testing of frequency controller on Chandrapur-
Ramagundam HVDC needed to be carried out urgently and needed to be coordinated
with frequency controller of Talcher-Kolar and Jaypore-Gazuwaka HVDC lines
He stated that synchronization of SR with NEW affects the flow gate like Wardha amp
Bhilai considerably and flows on various lines of MSETCL would alter and therefore
need detailed preparation He stated that synchronization with single 765 kV raichur-
Solapur does not comply to N-1 contingencies and it would be difficult to control flow
by three HVDC link Tripping of any singledouble poleamp mis operation of SPS would
lead to wide spread disturbance Constituents also expressed concern over single line
synchronization attempt Member Secretary stated that concern would be
communicate to Member GOampD CEA and NLDC
Sub Committee noted as above ITEM NO992 SHUTDOWN REQUEST FOR HVDC B2B VINDHYACHAL SUBSTATION
AGM(GM) WRLDC vide letter dated 11112013 intimated that they received proposal for shutdown of HVDC B2B Vindhyachal substation for overhauling of isolators for rectification of hot spot problem to avoid any contingency during upcoming winter season on 18112013 to 22112013 During this time HVDC Block1 will be under shutdown
OCC Sub-Committee agreed for outage
Minutes of 453rd OCC meeting held on 15th November 2013
ITEM NO 910 NOT INFORMING TO SLDC KALWA REGARDING MAJOR SYSTEM OPERATION INSTRUCTIONS ISSUED BY WRLDC TO PGCIL SS IN MAHARASHTRA
CE SLDC Kalwa Maharashtra intimated vide letter dated 11112013 that WRLDC
control room had instructions to PGCIL Ss in Maharashtra directly without giving any
information to SLDC Kalwa Following two such instances which had major impact of
power flow in Maharashtra network are mentioned below
1 On dated 10th Nov 2013 400 KV Parli(PG)-Pune(PG) II was taken in service at
2018 Hrs and 400 KV Parli(PG)-Pune(PG) ndash I was taken in service at 2151 Hrs
Effect Power flow on 400 KV Chakan-Lonikand and Pune(PG) ndash Kalwa
reversed load on Parli-Lonikand reduced Load on 220 KV Talegaon(PG)-
Talegaon(MS) SC increased to 280 MW
2 On dated 11th Nov 2013 at about 1040 Hrs FSC on 400 KV Raipur-Wardha
taken in sevice
Effect Flow on 400 KV Chandrapur-Warora ( SC quad line ) increased from
850 MW to 1128 MW flow on Chandrapur-II ndash Chandrapur-I ( SC twin moose
line ) increased from 360 MW to 685 MW Flow on 400 KV Raipur-Wardha DC
increased from 950 MW to 1450 MW APML generation reduced from 1950
MW to 1650 MW Maharashtra over drawl increased by 300 MW
Any switching operation in CTU network connected to Maharashtra system has major
impact on power flow and many times loading on lines become critical Only after
enquiry with WRLDC control room by SLDC Kalwa switching events are informed It is
informed that FSC was taken in service to improve voltages in South Maharashtra
please note that 400 KV Solapur-Kolhapur-I Kolhapur-Mhapusa-II RGPPL-
Nagothane-I amp RGPPL-Newkoyna-II lines were out of service in south Maharashtra
Voltage profile could have been improved by taking these lines in service
In integrated system any switching event in CTU network has impact on entire state
network and required to be carried out in coordination with state SLDC
Member Secretary WRPC stated that Item no 92 amp 910 are related to communication gap between SLDC MSETCL amp WRLDC with other He requested WRLDC amp SLDC Maharashtra to harmonize datainformation
Minutes of 453rd OCC meeting held on 15th November 2013
exchange and suggested to intimate each other in case of switching of elements in the State as well as ISTS grid WRLDC and SLDC Maharashtra agreed to the above suggestion of Member Secretary
The Sub-Committee noted as above
OTHER ITEMS FROM POWER GRID
SA-1 MOU for Tapping of Auxiliary Power supply from tertiary of 40022033 kV Transformer in POWERGRID sub-station
The ICTs in various POWERGRID substations having 33 kV Bushings which are
connected to AC Distribution Board through 33 kV440 V Transformers The Power
supply through this Transformer is tapped whenever the requirement arises
Generally the back up supply in event of the Auxiliary supply is provided through
DG Set In case of failure of DG Set power is taken from 33 kv of ICT
In this context it is to intimate that the 765 kV Station at Solapur is under construction
and likely to be commissioned by December end The station will have the line
coming from Raichur in Southern Region This will connect POWERGRID
SOUTHERN REGION and WESTERN REGION directly and the entire power system
of India will have one frequency
Further the Solapur sub-station would be the most important station and the failure of
AC power supply to the sub-station will affect the reliability of the station
The MOU for tapping of power through 33 kV side of the Transformer needs to be
addressed by local MSETCL and MSDCL offices
SLDC MSETCL assured to look in to the matter amp advised the PGCIL to consult with local Discom to short out the issue
SA-2 Dismantling of Shunt Reactor at Aurangabad sub-station
The clearances for shifting of Shunt Reactor from MSETCL Aurangabad sub-station to
POWERGRID Aurangabad sub-station was approved in earlier OCCM and
accordingly the Committee has agreed to dismantle the Reactor in Akola-Aurangabad
line I which is in operation without Reactor from last two months
Minutes of 453rd OCC meeting held on 15th November 2013

Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

OCC Approved Outage Statistics for Oct 2013
Approved Availed age
As agreed during the 452ND OCC meeting the respective utilities were requested to
apprise the sub-committee regarding reason for failing to avail approved outages
SE(Operation) WRPC pointed out that out of approved transmission outages bulk
quantum of outages are not availed by constituents even when there is no real time
condition problem He further stated that after approving outages for particular date
for particular line outage on parallel line or for the line in the same corridor is very
difficult owing to consideration of the fact that the approved outage would be availed
by that constituent But non-availing of such outage by any constituent deprives other
constituent requiring important outage Also sometimes the outages for two agencies
are clubbed together with change in dates suitable to one agency In case such
outage is not availed by the agency for whom the dates are suitable other agency
unnecessarily have to shuffle their planmanpower which cause trouble to them
He requested constituents to restrict the proposal on outages to really required The Sub-Committee noted as above

94 ENSURING INJECTION FROM (MOUDA + IEPL + TIRODA) WITHIN 1750 MW
WRLDC informed that a meeting was convened by WRPC on 26th June 2013 for discussing the SPS for Wardha flow gate It was decided in the meeting that the total injection by NTPC Mouda APL Tiroda and IEPL would be limited within 1750 MW It is being observed that the schedule issued by SLDC Maharashtra to Tiroda alone is around 1850 MW Consequently the loading on 400 kV Warora-Chadrapur is 900-950 MW loading on 400 kV Chandrapur-Chandrapur is 550-600 MW loading on 400 kV Wardha-Akola DC is 600-650 MW and loading on 400 kV Parli-Lonikhand is 500-550 MW each The system is N-1-1 insecure and following actions are desirable from SLDC Maharashtra
bull Ensure that despatch schedule given to Tiroda as well as its injection in real-time is in line with the WRPC MoM ref WRPCProtectionSPS2013-14949 dated 27062013
bull Ensure that the SPS of Tiroda is in operation bull Coordinate to increase generation at South Western Maharashtra
(KoynaJaigadRGPPL) to control the power flow on EHV lines in Maharashtra MSETCL agreed to the above actions suggested by WRLDC
Minutes of 453rd OCC meeting held on 15th November 2013
95 SPS IMPLEMENTATION STATUS
951 SPS for 765 kV Gwalior-Agra DC (Generation Run back Scheme in WR)
An SPS was envisaged for ensuring backing down WR generation by 500 MW ( VSTPS - 200 MW KSTPS - 120 MW CGPL - 180 MW) in case of sudden reduction of NR import from WR on Bina-Gwalior-Agra link by 1500 MW The matter was already discussed in 449th 450th and 451st OCC and 22nd WRPC meeting During the 451st OCC NTPC intimated that they have got the approval from their corporate centre and it was decided to implement the same within a month Regarding CGPL Power Grid representatives confirmed that tele-link was being provided at Mundra by them 952 SPS at APL Tiroda
WRLDC intimated that further subsequent to the synchronization of 400 kV Warora-Chandrapur-stg-II line -1 it is proposed that the logic at SPS needs to be revised as under
In addition to above action curtailment of drawal by Maharashtra would also be required either by increasing generation on South-west Maharashtra or distress load shedding in South Maharashtra
Contingency Desired automatic action through SPS
1 Tripping of 400 kV Warora-Chandrapur-stg-2 when the total powerflow on Wardhaflowgate plus 400 kV Warora-Chandrapur-stg-2 is more than the limit set for Wardhaflowgate
Trip one unit of APL Tiroda
2 Tripping of either 400 kV Wardha-Parli DC Trip one unit of APL Tiroda
3 Tripping of one ckt of 400 kV Wardha-ParliDC and one ckt of 400 kV Wardha-Akola DC
Trip one unit of APL Tiroda
4 Tripping of 400 kV Wardha-Akola DC Immediate Generation backing by 260 MW on running units at Tiroda
Minutes of 453rd OCC meeting held on 15th November 2013
Member Secretary WRPC stated that a separate meeting is to be called on 18112013 to resolve the above issue Subsequently a meeting was scheduled and held on 18112013 at WRLDC (minutes are enclosed at Annexure-94) wherein following two cases were discussed and concluded as follows
A) 400kV Chandrapur-Warora ckt in service
1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur-Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that
in the event of tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur-Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II is commissioned
Member Secretary WRPC further intimated that the above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora-Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur-Parli at Chandrapur-II

Annexure‐94
Minutes of the meeting held on 18112013 at Mumbai to discuss modificationrevision in SPS for Wardha flow gate
A meeting was held on 18112013 at Mumbai to discuss the revision of the existing SPS for control of power flow in the Wardha flow gate due to synchronization of 400kV Warora‐Chandrapur Ckt‐I as decided in the 453rd OCC Meeting of WRPC
The list of participants is enclosed at Annexure‐ 1
Shri S D Taksande Member Secretary WRPC welcomed the participants He stated that the SPS for controlling power flow through Wardha flow gate was finalized in the meeting held on 26062013 He further informed that the matter was discussed in the 453rd OCC meeting in light of synchronization of 400kV Warora‐Chandrapur Ckt‐I and the proposed synchronization of SR grid with NEW grid To restrict the flow through this corridor within safe limits for secure operation of the grid it was suggested by OCC to discuss the issue in a separate meeting Further the FSC on Raipur‐Wardha DC has increased the margin of the Bhilai flow gate but increased in injection of power at Wardha The network beyond Wardha towards Western part of Maharashtra is unable to mitigate this inflow as per the studies carried out by WRLDC resulting in frequent violation of the margin limit He requested WRLDC and MSETCL to clarify on the following issues
1) Reasons for revising the Wardha flow gate margin of 2480MW decided in the 26062013 meeting to 2050MW communicated by WRLDC vide their letter WRLDCMO‐I176113532 dated 25102013 and whether the synchronization of Chandrapur ‐Warora Ckt has affected the network flow through Wardha flow gate
2) There is no change in network topology of the Wardha flow gate comprising of 400kV Wardha‐Akola DC and 400kV Wardha‐Parli DC Whether the FSC on Raipur‐Wardha DC is affecting the margins of Wardha flow gate
3) Commissioning schedule of the 400kV Chandrapur 2‐Warora ckt‐2 and the LILO of second circuit of Chandrapur‐Parli ckt at Chandrapur‐II since this would further require modificationrevision of the SPS
SLDC Maharashtra representative intimated that the 400kV Warora‐ Chandrapur Ckt‐2 would be commissioned within one week and LILO of second circuit of Chandrapur‐ Parli ckt at Chandrapur‐II would take around one month The flow on 400kV Chandrapur‐ Warora ckt is around 900MW and would increase to around 1200‐1300 MW after charging the second circuit and completion of LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II He further informed that even after synchronization of second circuit of 400kV Chandrapur‐ Warora ckt the flow will have to be restricted to 900MW till the commissioning of the LILO of second circuit of Chandrapur Parli ckt at Chandrapur‐II
WRLDC representative clarified that the margin of Wardha flow gate has not been reduced and the margin of 2480MW shall be limited to 2050MW in the event of tripping of 400kV Warora‐ Chandrapur Ckt and therefore requested that the SPS logic for backing down generation at APL Tiroda envisaged earlier shall be modified and one unit of 660MW at APL Tiroda be tripped under the contingency of loss of 400kV Warora‐ Chandrapur Ckt‐1
APL representative stated that after synchronization of the 400kV Warora‐ Chandrapur Ckt‐1 during violation of the limits the SPS has operated successfully however even after backing down of generation at APL Tiroda due to SPS operation has not reduced the flow on Wardha flow gate significantly (Sensitivity of the APL generation on Wardha flow gate envisaged in the existing SPS have an effect of 50 reduction of flow on Wardha flow gate) The above sensitivities have not been observed during the recent operation of the SPS and the relieving of Wardha flow gate was very less The units at APL are observing frequent unloading and loading of its units due to operation of SPS since there is frequent violation of the Wadha flow gate limit in the recent past Further if tripping of Unit is incorporated in the SPS tripping of the unit may not give desired relief due to less sensitivity
WRLDC representative stated that the increase in power at Bhilai gate is due to increase in UI power from ER therefore load reduction in Western part of Maharashtra or increase in generation of Koyna is the only resort to control the power flow
MSETCL representative stated that they will take all necessary manual steps such as picking of generation at Koyna etc However he suggested that the manual Load shedding is a tedious process and would take considerable time Further he pointed out that in spite of 400kV Wardha‐Parli being a Quad conductor the margin considered for these lines is around 600MW each as against the margin considered for Raipur‐Wardha line (Quad conductor) with FSC is considered significantly more than that of 400kV Wardha‐Parli Putting FSC only enhances the power transfer capability and not the margin He further suggested that at least FSC on one of the Raipur‐Wardha lines be bypassed to relieve congestion at Wardha
POWERGRID representative stated that the FSC can be bypassed automatically by taking signal from Wardha
The above was discussed in detail and following was decided in the meeting
A) 400kV Chandrapur‐Warora ckt in service 1) SLDC Maharashtra may take appropriate manual actions (such as generation pickup at
Koyna RGPPL and Parli and control generation in Wardha pocket) to relive the congestion of the corridor and load shedding in Western Maharashtra as a last resort
2) The short term schedules shall be curtailed in the event of crossing of the margins as per the regulatory frame work
3) Since the sensitivity of APL Tiroda generation to the Wardha flow gate is significantly low in case of Warora Chandrapur ckt in service therefore WRLDC would suggest the factor by which the generation of APL Tiroda is required to be backed down (if it is found that the effect of backing down of generation at APL Tiroda under such condition is effective in controlling the flow through Wardha flow gate) to control incremental flow on Wardha flow gate this additional set of logic will be incorporated
B) 400kV Chandrapur‐Warora ckt out of service 1) The SPS suggested in the 26062013 meeting shall be in operation such that in the event of
tripping of Warora Chandrapur line backing down of 600MW at APL Tiroda shall be wired up All other settingsconditions decided in the 26062013 meeting shall be same
2) In the event of tripping of Warora Chandrapur line POWERGRID shall automatically bypass FSC on one circuit of Raipur‐Wardha line
3) This arrangement shall be implemented till the 2nd ckt of Warora Chandrapur and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II is commissioned
The above suggestionsmodifications in the SPS of Wardha flow gate will be reviewed after synchronization of the 400kV Warora‐Chandrapur ckt 2 and LILO of 2nd ckt of Chandrapur‐Parli at Chandrapur‐II
The meeting ended with thanks to the Chair

B) FREQUENCY CONTROL FUNCTION TEST (SOUTH SIDE-POWER DECREASE) Pre condition (to be coordinated by RLDCNLDC)
-Power flow 600MW -Direction West -gt South -Both poles in service in station mode -Both west and south freq are within normal range
Operator action (HVDC bhadrawati)
a) Select the freq control on south side in the mimic b) With this the actual south freq shall be set present freq demand value (Target freq) say lsquoxrsquo c) The freq slope will also be activated to previous set value
d) Adjust the freq slope to 4 on the mimic (ie 50MW01Hz)
e) Now change and set freq demand value to x-02Hz on south side Thus the new freq demand shall become active
f) The freq control shall operate and shall modulate the DC power (Power decrease) to bring the actual south freq to new freq demand value
g) The contribution on activation of freq control shall be of the order of 100MW to 400MW depending upon selection of differential freq range determined in step lsquoersquo above
h) Note down the values of West freq South freq DC power preferably every 30Sec
i) Change the slope to 2 and repeat the readings as above

C) FREQUECNY LIMIT FUNCTION TEST (SOUTH SIDE-Power Increase)
Pre condition (to be coordinated by RLDCNLDC)
-Power flow 600MW -Direction West -gt South -Both poles in service in station mode -Both west and south freq are within the normal range
Operator action (HVDC bhadrawati)
- Ensure Frequency limit function on both south and west side are in disabled condition
- Set the frequency limit function on west side as follows Centre freq=500Hz Range=+- 10Hz
- Enable the freq limit function on west side - Note the present running freq of south bus say lsquoxrsquo - Set the freq limit function at south side such that the lower freq limit is x+005Hz
Keep the range of +-005Hz Ex If south freq is 4990Hz Then set the center freq to 5000Hz and range to 005Hz
- Set slope at 3 - Enable the freq limit function on south side - With this freq limit function on south side will be activated and power flow will
increase in west -gt south direction - Note down the following readings
West freq south freq power time
- The contribution on activation of freq limit shall be of the order of 100MW to 400MW

D) FREQUECNY LIMIT FUNCTION TEST (SOUTH SIDE-Power decrease)
Pre condition (to be coordinated by RLDCNLDC)
-Power flow 600MW -Direction West -gt South -Both poles in service in station mode -Both west and south freq are within normal range
Operator action at HVDC station
- Ensure Frequency limit function on both south and west side are in disabled condition
- Set the frequency limit function on west side as follows Centre freq=500Hz Range=+- 10Hz
- Enable the freq limit function on west side - Set the freq limit function at south side such that the upper freq limit is 01Hz below
the running frequency Keep the range of +-01Hz Ex If south freq is 5000Hz Then set the center freq to 4980Hz and range to 010Hz
- Set slope at 2 - Enable frequency limit function on south side - With this freq limit function on south side will be activated and power flow will
decrease in west -gt south direction - Note down the following readings
West freq south freq power time
- The contribution on activation of freq limit shall be of the order of 100MW to 400MW
During changing of center frequency or range frequency first put frequency limiting function in OFFDisable mode
