All the DISCOMs supply electricity to all categories of users including domestic, commercial, industrial (small, medium and large) and agricultural consumers. The power distribution system has large & complex distribution network infrastructure which carries the energy from the power sub stations (66/11lkV) through the HT and LT lines up to the consumers’ premises. For the day to day operation ,DISCOM has huge human capital that works round the clock. Technical and commercial losses occurring due to various reasons affect the financial health of the DISCOM severely. All the four DISCOMS in Gujarat have already taken various initiatives in order to improve its operational efficiency and for delivering enhanced services to the consumers under their jurisdiction. The distribution companies are in the process of implementing various IT systems under RAPDRP part-A for which contracts are already been awarded.

3. Utility Vision

The Company has the vision of providing customer satisfaction through service excellence. Company is committed to achieve the goal of providing reliable and quality power at competitive cost and to reach global standards in reducing distribution losses.

In order to meet the objectives and go upward in the value chain, DISCOMs of Gujarat have taken various initiatives like enabling IT systems in all the business process, installing supervisory, remote monitoring and enterprise resource planning tools along with investments in communication , IT and modernization of distribution networks.

With the proposed SCADA/DMS systems under R-APDRP PART-A scheme along with planned investments under R-APDRP PART-B, it is expected to deliver highly reliable & improved quality supply to its consumers meeting various mandatory Standards of Operation(SOP) proposed by state regulatory board. During contingencies with help of real time monitoring and analysis functions remedial actions shall be taken by SCADA/DMS either by self designated rules or intelligence-in- response to system state at different operational constraints. The systems to be implemented shall have necessary scalability and adaptation to the future standards and regulations and shall be a step towards Smart Grid.

The communication backbone for the envisaged SCADA/DMS system consists MPLS-VPN/MLLN and 3G/CDMA/GPRS across the project area. The below figure depicts typical connectivity envisaged by the DISCOMs for its towns.



Figure 1:SCADA/DMS System connectivity envisaged by DISCOM

Divisional offices, Circle office are identified as the functional area of DISCOMs for SCADA/DMS implementation, the monitoring should be possible from the proposed system for any remote VDU locations. SIA has to do site study of the project area and define the interface requirements for SCADA/DMS system and for necessary connections with switchgears including protection relays/controlling equipments (mechanical/numerical/microprocessor). The site study team shall include all necessary experts to understand and identify the above requirements. Proposed system envisages the following key functions at minimum and SIA has to strictly comply with all international and national standards and codes while implementing.

i. The proposed system consists of RTU, FRTU and FPI Modems at field and SCADA/DMS at Control Centre.

ii. DMS functions at control centre should enable automatic and manual operations of the network devices and monitor all the power meters of interest.

iii. All the data pertaining to substation shall be collected by RTU and the same shall be send to control centre via MPLS-VPN network. If MPLS-VPN is not feasible at a specific location alternate options like leased line, broad band shall be considered by the SIA.

iv. Status and indications data from 11 KV distribution assets like Ring Main Units (RMUs), Fault Passage Indicators and Sectionalizers are acquired by FRTU communicating to



control centre over wireless mobile network(3G/CDMA/GPRS). Stand alone FPIs are to be communicated to control centre using 3G/CDMA/GPRS modems. The communication media shall be 3G and if 3G is not available in any particular city area bidder can go for the CDMA or GPRS. But then, the used equipments shall be easily upgradable to 3G without any additional cost.

v. The modems attached with the FRTU shall be capable of adapting latest wireless transfer technology including 3G, CDMA&GPRS. SIA should ensure all types of data quality, reliability and security over desired communication links as per the model technical specification (MTS). The Modem shall support 3G with backward compatible for CDMA/GPRS.

vi. Remote Visual Data Units (VDU) and Local Data Monitoring Systems(LDMS) at all functional offices should allow monitoring of the distribution assets depending upon user privileges defined. Connectivity to the offices shall have necessary bandwidth for the data exchanges.

vii. GIS and network model information are to be fetched from upcoming IT system using middleware or interface adapters.

viii. Minimum band width requirement estimated for the MPLS-VPN connection at all towns is given in below table, however all bandwidth requirements shall be estimated by SIA in order to attain the desired level of system reliability and availability specified in the MTS. Minimum bandwidth for all the MPLS-VPN at a typical SCADA/DMS control Center shall be as shown below:
