Application

The 7UM6 protection relays ofthe SIPROTEC 4 range arecompact multifunction unitswhich have been developedfor small to medium-sizedpower generation plants. Theyincorporate all the necessaryprotective functions and areespecially suitable for the pro-tection of:− Hydro and pumped-storage

generators− Cogeneration stations− Private power stations using

regenerative energy sourcessuch as wind or biogases

− Power generation withdiesel generators

− Gas turbine power stations− Industrial power stations

and− Conventional steam power

stations.They can also be employed forprotection of motors and trans-formers.The numerous other additionalfunctions assist the user in en-suring cost-effective systemmanagement and reliablepower supply. Measured val-ues display current operatingconditions. Stored status indi-cations and fault recording pro-vide assistance in fault diagno-sis not only in the event of adisturbance in generator oper-ation.Combination of the unitsmakes it possible to imple-ment effective redundancyconcepts.

Uniform design

The SIPROTEC 4 units have auniform design and a degreeof functionality which repre-sents a whole new quality inprotection and control.Local operation has been de-signed according to ergonomiccriteria. Large, easy-to-readdisplays were a major designaim. The DIGSI 4 operatingprogram considerably simpli-fies planning and engineeringand reduces commissioningtimes.

Highly reliable

The 7UM6 hardware is basedon 20 years of Siemens experi-ence with numerical protectionequipment. State-of-the-arttechnology and a high-effi-ciency 32-bit microprocessorare employed. Production issubject to exacting qualitystandards. Special attentionhas been paid to electromag-netic compatibility and thenumber of electronic moduleshas been drastically reducedby the use of highly integratedcircuits.The software design incorpo-rates accumulated experienceand the latest technical knowl-edge. Object orientation andhigh-level languageprogramming, combined withthe continuous quality assur-ance system, ensure maxi-mized software reliability.

Programmable logic

The integrated programmablelogic function allow the user toimplement his own functionsfor automation of switchgear(interlocking) via a graphic userinterface. The user can alsogenerate user defined mes-sages. Adjustments can easilybe made to the varying powerstation requirements.

Protection functions

Numerous protection func-tions are necessary for reliableprotection of electrical ma-chines. Their extent and com-bination are determined by avariety of factors, such as ma-chine size, mode of operation,plant configuration, availabilityrequirements, experience anddesign philosophy.This leads of necessity tomultifunctionality, which is im-plemented in outstandingfashion by numerical technol-ogy.In order to satisfy differing re-quirements, the combinationof functions is scalable (seeTable 1). Selection is facilitatedby division into three groups.

• Basic configuration

One application is concen-trated on small generators oras backup protection for largergenerators. The function mix isalso an effective addition totransformer differential protec-tion with parallel-connectedtransformers. The functionsare also suitable for systemdisconnection.

• Standard configuration

This function mix is recom-mended for generator outputsexceeding 1 MVA.It is also suitable for protectionof synchronous motors.Another application is as back-up protection for the largerblock units.

• Full configuration

Here, all protection functionsare available and are recom-mended from generator out-puts exceeding 5 MVA.Backup protection for thelarger block units is also a rec-ommended application.

Measurement

Based on years of experience,high-efficiency protection algo-rithms have been imple-mented which are adapted es-pecially to generator behavior.Thus, irrespective of the gen-erator frequency at the time, ahigh degree of measurementaccuracy is achieved by virtueof the sampling frequency cor-rection in the range of11 to 69 Hz. Filter algorithmssuppress the higher frequencytransient phenomena andaperiodic DC components.

Unit configuration

The units are available in 2 ver-sions – as the 7UM611 in1/3 19-inch and the 7UM612 in½ 19-inch width. The softwarefunctions and subassemblybreakdown are identical. The7UM612 possesses more bi-nary inputs and outputs and issuitable for incorporation inolder or more complex plants.

Communication

The SIPROTEC 4 units pos-sess up to three serialinterfaces:− Front interface for connect-

ing a PC− Service interface for con-

necting a PC via modem− System interface for con-

necting to a control systemvia IEC 60870-5-103 orPROFIBUS-DP;Modbus RTUand an input for

− Time synchronization viaIRIG B or DCF 77

Operational measured val-ues

In order to assist system man-agement and for commission-ing purposes, all relevant mea-sured values are displayed asprimary and secondary valueswith unit and values relating tothe object to be protected.The measured values can alsobe transferred via the serial in-terfaces.In addition, the programmablelogic permits limit value scansand status indications derivedtherefrom.Metered values are available inthe form of energy meteredvalues for the active and reac-tive energy supplied and arealso provided by anelapsed-hour meter.

Operational indications

The SIPROTEC 4 units provideextensive data for fault analy-sis, as well as control. All indi-cations listed below are pro-tected against power supplyfailure.

• Fault indications

The last eight faults arestored in the unit at all times.A fresh fault erases the old-est one. The fault indicationspossess a time resolution of1 ms. They provide detailedinformation on fault history.The buffer memory is de-signed for a total of 600 indi-cations.

• Operational indications

All indications that are not di-rectly associated with thefault (e.g. operating orswitching actions) are storedin the status indicationbuffer. The time resolution is1 ms, buffer size: 200 indica-tions.

Fault recording up to 5 or 80seconds

An instantaneous value orRMS value recorder is pro-vided. The firmware permitsstorage of 8 fault recordings.Triggering can be effected bymeans of pickup, tripping, bi-nary input, the DIGSI 4 operat-ing program or by the controlsystem.In the case of the instanta-neous value recording, the in-put variables (4 x u and 4 x i )are recorded at increments of1.25 ms at 50 Hz or 1.04 ms at60 Hz. The total duration is5 seconds. If the time is ex-ceeded, the oldest fault re-cording in each case is over-written.If protection functions withlong delay times are activated,the RMS Value recording isrecommended. Storage of rel-evant calculated variables (V1,VE, I1, I2, IEE, P, Q, f-fn) takesplace at increments of one cy-cle. The total time is 80 sec-onds.

Time synchronization

A battery-backed clock is astandard component and canbe synchronized via a synchro-nization signal (DCF77; IRIG Bvia satellite receiver), binary in-put, system interface orSCADA (e.g. SICAM). A dateand time are assigned to everyindication.

Freely assignable binary in-puts and outputs

Binary inputs, output relaysand the LEDs are assignablewith indications, user-specifi-cally and independently of oneanother.The tripping matrix is imple-mented by means of the firm-ware. It is simplicity itself toset the tripping programs. Thefirmware assists primary test-ing by functional suppressionof the trip command.

Continuous self-monitoring

The hardware and softwareare continuously monitored. Ifabnormal conditions are de-tected, the unit signal immedi-ately. In this way, a great de-gree of safety, reliability andavailability is achived.

Reliable battery monitoring

The battery buffers the indica-tions and fault recordings inthe event of power supplyvoltage failure. Its function ischecked at regular intervals bythe processor. If the capacityof the battery is found to bedeclining, an alarm indication isgenerated.All setting parameters arestored in the Flash-EPROMwhich are not lost if the powersupply or battery fails. TheSIPROTEC 4 unit remains fullyfunctional.

DIGSI 4, the PC program foroperating protection relays

The PC operating programDIGSI 4 is the interface be-tween the user and theSIPROTEC 4 units. It has amodern, intuitive operator in-terface. With DIGSI 4, theSIPROTEC 4 units can be con-figured and queried - it is a tai-lored program for the energysupply and manufacturing in-dustries.The software runs underWindows (Version 95 andhigher, as well as NT).

Simple protection setting

The protection functions re-quired can be selected fromthe wide range provided(Fig. 7). This means that trans-parency in subsequent menusis enhanced.The newly introduced primarydisplay (settings are related tonominal values of the object tobe protected) permits stan-dardization of the setting val-ues. Pressing a button effectsconversion to secondary val-ues and loading into the pro-tection unit.

DIGSI 4 matrix

The DIGSI 4 matrix allows theuser to see the overall view ofthe unit configuration at aglance. For example, you candisplay all the LEDs that havebinary inputs or show any indi-cation that are connected tothe relay. And with one click ofthe button connections can beswitched.By utilizing filter functions, onlyallocated information is ren-dered visible. In addition, it ispossible to alter the viewingmodes. In “Binary Output”viewing mode (output relays),the tripping matrix is clearlydisplayed.

CFC: Reduced time and plan-ning for programming logic

With the help of the CFC (Con-tinuous Function Chart), youcan configure interlocks andswitching sequences simplyby drawing the logic se-quences; no special knowl-edge of software is required.Logical elements, such asAND, OR and time elements,measured limit values, etc. areavailable.

Commissioning

Special attention has beenpaid to commissioning. All bi-nary inputs and outputs can beread and set directly. This cansimplify the wire checking pro-cess significantly for the user.For primary testing, it is possi-ble to activate a transmissionlockout to prevent any infor-mation being transmitted viathe interface to the controlroom. On the other hand, indi-cations can be transmitted in-tentionally for test purposes.

DIGRA 4: Universal programfor fault recording evalua-tion

Fault recordings stored in theprotection system can be visu-ally displayed and evaluated inclear form. It is readily possibleto calculate harmonics, to viewindividual measuring points, todisplay vector and locus dia-grams etc.The Comtrade format makes itpossible to analyze any desiredfault recordings.

With respect to communica-tion, particular emphasisplaced on high levels of flexibil-ity, data integrity and utilizationof standards common in en-ergy automation. The designof the communication mod-ules permits interchangeabilityon the one hand, and on theother hand provides opennessfor future standards (for exam-ple, Industrial Ethernet).

Local PC interface

The PC interface accessiblefrom the front of the unit per-mits quick access to all param-eters and fault event data. Ofparticular advantage is the useof the DIGSI 4 operating pro-gram during commissioning.

Rear-mounted interfaces

On the rear of the unit are lo-cated two communicationmodules which incorporate op-tional equipment comple-ments and readily permit retro-fitting. They assure the abilityto comply with the require-ments of different communi-cation interfaces (electrical oroptical) and protocols(IEC 60870, PROFIBUS,DIGSI).The interfaces make provisionfor the following applications:

• Service interface

In the RS485 Version, sev-eral protection units can becentrally operated withDIGSI4. On connection of amodem, remote control ispossible. This provides ad-vantages in fault clearance,in particular in unmannedpower stations.

• System interface

This is used to carry outcommunication with a con-trol or protection and controlsystem and supports, de-pendent on the module con-nected, a variety of commu-nication protocols and inter-face designs.

IEC 60870-5-103

IEC 60870-5-103 is an interna-tionally standardized protocolfor the efficient solving ofcommunication problems inthe protected area.IEC 60870-5-103 is supportedby a number of protection unitmanufacturers and is usedworld-wide.The generator protection func-tions are stored in the privatepart (published) of the proto-col.

PROFIBUS-DP

PROFIBUS is an internationallystandardized communicationsystem (EN 50170) for com-munication problem solving.Profibus is supported interna-tionally by several hundredmanufacturers and has to datebeen used in more than1,000,000 applications all overthe world.With the Profibus-DP the pro-tection can be directly con-nected to a SIMATIC S5/S7.The transferred data are faultdata, measured values and in-formation from or to the logic(CFC).

MODBUS RTU

MODBUS is also a widely uti-lized communication standardand is used in numerous auto-mation solutions.

Safe bus architecture

RS485 busWith this data transmissionvia copper conductors elec-tromagnetic fault influ-ences are largely elimi-nated by the use oftwisted-pair conductor.Upon failure of a unit, theremaining system contin-ues to operate without anyfaults. Fiber-optic double ring

System solution

SIPROTEC 4 is tailor-made foruse in SIMATIC-based auto-mation systems.Via the PROFIBUS DP, indica-tions (pickup and tripping) andall relevant operational mea-sured values are transmittedfrom the protection device.Via modem and service inter-face, the protection engineerhas access to the protectiondevices at all times. This per-mits remote maintenance anddiagnosis (cyclic testing).Parallel to this, local communi-cation is possible, for exampleduring a major inspection.

Definite time-overcurrentprotectionI>, I>>(ANSI 50, 51, 67)

This protection function com-prises the short-circuit protec-tion for the generator and alsothe back-up protection for up-stream devices such as trans-formers or power system pro-tection.An undervoltage stage at I>maintains the pickup whenduring the fault the currentfalls below the threshold. Inthe case of a voltage drop onthe generator terminals, thestatic excitation system can nolonger be sufficiently supplied.This is one reason for the de-creasing of the short-circuitcurrent.The I>> stage can be imple-mented as high-set instanta-neous trip stage. With the inte-grated directional function itcan be applied for generatorswithout star point c.t. (see Fig-ure 18).

Inverse time-overcurrentprotection (ANSI 51V)

This function also comprisesshort-circuit and back-up pro-tection and is used for powersystem protection with currentdependent protection devices.IEC and ANSI characteristicscan be selected (Table 2).By evaluating the generatorterminal voltage, the currentfunction can be controlled.The “controlled” version re-leases the sensitive set cur-rent stage.With the “restraint” versionthe pickup value of the currentis lowered linearly with de-creasing voltage.The fuse-failure-monitor pre-vents unwanted operation.

Stator overload protection(ANSI 49)

The task of the overload pro-tection is to protect the statorwindings from high, continu-ous overload currents. All loadvariations are evaluated by themathematical model used. Thethermal effect of the rms cur-rent value forms the basis ofthe calculation. This conformsto IEC 60255-8. In dependencyof the current the cooling timeconstant is automatically ex-tended. If the ambient temper-ature or the temperature of thecoolant are injected via thePROFIBUS-DP, the model au-tomatically adapts to theambient conditions; otherwisea constant ambient tempera-ture is assumed.

Negative sequenceprotection(ANSI 46)

Asymmetrical current loads inthe three phases of a genera-tor cause a temperature rise inthe rotor because of the nega-tive sequence field produced.This protection detects anasymmetrical load in three-phase machines. It functionson the basis of symmetricalcomponents and evaluates thenegative sequence of thephase currents. The thermalprocesses are taken into ac-count in the algorithm andform the inverse characteristic.In addition, the negativesequence is evaluated by anindependent stages (alarm andtrip) which are supplementedby a time-delay element (seeFigure 19).

Underexcitation protection(ANSI 40)

Derived from the generatorterminal voltage and current,the complex admittance is cal-culated and corresponds to thegenerator diagram scaled inper unit. This protection pre-vents damage due to loss ofsynchronism resulting fromunderexcitation. The protec-tion function provides threecharacteristics for monitoringstatic and dynamic stability. Incase of exciter failure, fast re-sponse of the protection canbe ensured via binary input.This input releases a timerwith a short time delay..The straight-line characteristicsallow an optimum adaption ofthe protection of the generatordiagram (see Figure 20). Theper-unit-presentation of the di-agram allows direct read-out ofthe setting values.The positive sequence sys-tems of current and voltageare used to calculate theadmittance. This ensures thatthe protection always operatescorrectly even with asymmet-rical network conditions.In the case of a voltage devia-tion from the rated voltage, theadmittance calculation has theadvantage that the characteris-tics move in the same direc-tion as the generator diagram.

Reverse power protection(ANSI 32R)

The reverse power protectionmonitors the direction of ac-tive power flow and respondswhen the mechanical energyfails because then the driveenergy is taken from the net-work. This function providedby the 7UM6 can be used foroperational shutdown of thegenerator but also preventsdamage to the steam turbines.The reverse power is calcu-lated from the positive-sequence systems of currentand voltage. Asymmetricalnetwork faults therefore donot cause reduced measuringaccuracy. The position of theemergency trip valve is in-jected as binary informationand is used to switch betweentwo switch-off command de-lays. When applied for motorprotection, the sign of the ac-tive power can be reversed viaparameters.

Forward power protection(ANSI 32F)

Monitoring of the active powerproduced by a generator canbe useful for starting up andshutting down generators.One stage monitors thresholdbeyond one limit value whileanother stage monitorsthreshold below another limitvalue. The power is calculatedusing the positive-sequencecomponent of current and volt-age.

Impedance protection(ANSI 21)

This fast short-circuit protec-tion protects the generator,the generator transformer andis a backup protection for thepower system. This protectionhas two settable impedancestages; in addition, the firststage can be switched over viabinary input. With the circuit-breaker in “open” position(see Figure 21) the impedancemeasuring range can be ex-tended. The overcurrentpickup element with under-voltage seal-in ensures a reli-able pickup and the loop selec-tion logic a reliable detection ofthe faulty loop. It makes alsopossible a correct measuringvia the generator transformer.

Undervoltage protection(ANSI 27)

The undervoltage protectionevaluates the positive-se-quence components of thevoltages and compares themwith the threshold values.There are two stages availableThe undervoltage function isused for asynchronous motorsand pumped-storage stationsand prevents the volt-age-related instability of suchmachines.The function can also be usedfor monitoring purposes.


Figure 20Characteristic of underexitation protection

Figure 21Grading of impedance protection

Overvoltage protection(ANSI 59)

This protection prevents insu-lation faults that result whenthe voltage is too high.Either the maximumline-to-line voltages or thephase-to-earth voltages (forlow-voltage generators) can beevaluated. The measuring re-sults of the line-to-line voltagesare independent of the neutralpoint displacement caused byearth-faults. This function isimplemented in two stages.

Frequency protection

(ANSI 81)

The frequency protection pre-vents an unpermissible stressof the equipment (e.g. turbine)in case of under- or over-frequency. It also serves as anmonitoring and control ele-ment.The function has four stages ;the stages can be imple-mented either as under-frequency or over-frequencyprotection. Each stage can bedelayed separately.Even in the case of voltagedistortion, the frequency mea-suring algorithm reliably identi-fies the fundamental wavesand determines the frequencyextremely precisely.Frequency measurement canbe blocked by using an un-dervoltage stage.

Overexcitation protectionVolt/Herz(ANSI 24)

The overexcitation protectionserves for detection of anunpermissible high induction(proportional to V/f) in genera-tors or transformers, whichleads to a thermal overloading.This may occur when startingup, shutting down under fullload, with weak systems orunder isolated operation. Theinverse characteristic can beset via seven points derivedfrom the manufacturerdata/curve.In addition, an independentalarm stage and aninstantaneous stage can beused.For calculation of the V /f ratio,frequency and also the highestof the three line-to-line volt-ages are used. The frequencyrange that can be monitoredcomprises 11 to 69 Hz.

Stator earth-fault protection,non-directional, directional(ANSI 59N, 64G, 67G)

Earth faults manifest them-selves in generators that areoperated in isolation by theocurance of a displacementvoltage. In case of unit connec-tions, the displacement volt-age is an adequate, selectivecriterion for protection.For the selective earth-faultdetection, the direction of theflowing earth-current has to beevaluated too, if there is adirect connection betweengenerator and busbar.The protection relay measuresthe displacement voltage at av.t. located at the transformerstar point or at the brokendelta-winding of a v.t. As anoption it is also possible to cal-culate the zero-sequence volt-age from the phase-to-earthvoltages. Depending on theload resistor selection 90 to95 % of the stator winding of agenerator can be protected.A sensitive current input isavailable for the earth currentmeasurement. This inputshould be connected to acore-balance current trans-former. The fault direction isdeduced from the displace-ment voltage and earth cur-rent. The directional character-istic (straight line) can be easilyadapted to the system condi-tions. Effective protection fordirect connection of a genera-tor to a busbar can thereforebe created. During startup, it ispossible to switch over fromthe directional to thedisplacement voltage mea-surement via an externally in-jected signal.Depending on the protectionsetting, various earth fault pro-tection concepts can be imple-mented with this function (seeFigs. 23 to 27).

Sensitive earth-faultprotection(ANSI 50/51GN, 64R)

The sensitive earth current in-put can also be used as sepa-rate earth-fault protection. It isof two-stage form. Secondaryearth currents of 2 mA orhigher can be reliably handled.Alternatively, this input is alsosuitable as rotor earth faultprotection. A voltage withrated frequency (50 or 60 Hz)is connected in the rotor circuitvia the interface unit 7XR61. Ifa higher earth current is flow-ing, a rotor earth fault has oc-curred. Measuring circuit mon-itoring is provided for this ap-plication (see Figure 26).

100%-stator earth-fault pro-tection with 3

rdharmonic

(ANSI 59TN, 27TN (3rd

H.))

Owing to the design, the gen-erator produces a 3rd har-monic that forms a zero sys-tem. It is verifiable by the pro-tection on a broken delta wind-ing or on the neutral trans-former. The magnitude of thevoltage amplitude depends onthe generator and its opera-tion.In the event of an earth fault inthe vicinity of the neutral pointthere is a voltage displace-ment in the 3rd harmonic(dropping in the neutral pointand rising at the terminals).

Depending on the connectionthe protection must be set ineither undervoltage orovervoltage form. It can alsobe delayed. So as to avoidoverfunction, the active powerand the positive sequencevoltage act as enabling criteriaThe final protection setting canbe made only by way of a pri-mary test with the generator.

Breaker failure protection(ANSI 50BF)

In the event of scheduleddowntimes or a fault in thegenerator, the generator canremain on line if the circuit-breaker is defective and couldsuffer substantial damage.Breaker failure protection eval-uates a minimum current andthe circuit-breaker auxiliarycontact. It can be started by in-ternal protective tripping or ex-ternally via binary input.Two-channel activation avoidsoverfunction (see Figure 22).

This protection has the func-tion of limiting the damage ofthe generator in the case of anunintentional switch-on of thecircuit-breaker whether thegenerator is standing still or ro-tating without being excited orsynchronized. If the networkvoltage is connected the gen-erator starts as an asynchron-ous machine with a large slipand this leads to excessivelyhigh currents in the rotor.A logic circuit consisting ofsensitive current measure-ment for each phase, mea-sured variable detector, timecontrol and blocking as of aminimum voltage, leads to aninstantaneous trip command.If the fuse failure monitor re-sponds, this function is inef-fective.

External trip coupling

For recording and processingof external trip informationthere are 2 (for 7UM611) or4 (for 7UM612) binary inputs.They are provided for informa-tion from the Buchholz relay orgenerator-specific commandsand act like a protective func-tion. Each inputs opens a faultevent and can be individuallydelayed by means of a timer.

Trip circuit supervision(ANSI 74TC)

One or two binary inputs canbe used for monitoring the cir-cuit-breaker trip coil includingits incoming cables. An alarmsignal occurs whenever the cir-cuit is interrupted.

Phase rotation reversal

In pumped-storage power sta-tions it is possible for a binaryinput to perform matching tothe current phase rotation(generator / motor operationvia phase rotation reversal).

2 predefinable parametergroups

In the protection the settingvalues can be stored in twodatasets. In addition to thestandard parameter group, thesecond group is provided forcertain operating conditions(pumped-storage power sta-tions). It can be activated viabinary input, local control orDIGSI 4.

Lockout(ANSI 86)

All binary outputs (alarm or triprelays) can be stored like LEDsand reset using the LED resetkey. The lockout state is alsostored in the event of supplyvoltage failure. Reclosure canonly occur after the lockoutstate is reset.

Fuse failure and other moni-toring

The relay comprises high-per-formance monitoring for thehardware and software.The measuring circuits, ana-log-digital conversion, powersupply voltages, memoriesand software sequence(watchdog) are all monitored.The fuse failure function de-tects failure of the measuringvoltage due to short-circuit oropen circuit of the wiring or v.t.and avoids overfunction of theundervoltage elements in theprotection functions.The positive and nega-tive-sequence system (voltageand current) are evaluated.

Filter time

All binary indications can besubjected to a filter time (indi-cation suppression).


Direct generator-busconnection

Fig. 23 illustrates the recom-mended standard connectionif several generators supplyone busbar. Phase-to-earthfaults are disconnected by em-ploying the directionalearth-fault criterion. Theearth-fault current is driventhrough the cables of the sys-tem. If this is not sufficient, anearthing transformer con-nected to the busbar suppliesthe necessary current (maxi-mum approximately 10 A) andpermits a protection range ofup to 90 %. The earth-faultcurrent should be detected bymeans of core-balance currenttransformers in order toachieve the necessary sensi-tivity. The displacement volt-age can be used as earth-faultcriterion during starting opera-tions until synchronization isachieved.

Direct generator-bus con-nection with low-resistanceearthing

If the generator neutral pointhas low-resistance earthing,the connection illustrated inFig. 24 is recommended. Inthe case of several generators,the resistance must be con-nected to only one generator,in order to prevent circulatingcurrents (3rd harmonic).For selective earth-fault detec-tion, the earth-current inputshould be looped into the com-mon return conductor of thetwo current transformer sets(differential connection). Thecurrent transformers must beearthed at only one point. Thedisplacement voltage VE is uti-lized as additional enable crite-rion.Balanced DE current trans-formers are desirable with thisform of connection. In thecase of higher generatorpower (for example, IN approxi-mately 2000 A), current trans-formers with a secondarynominal current of 5 A are rec-ommended.



Connections/Typical applications

Figure 24

Figure 23

Direct generator-bus con-nection with high-resistancegenerator neutral earthing

With this system configura-tion, selective earth-fault de-tection is implemented on thebasis of the lower fault cur-rents through the differentialconnection of core-balancecurrent transformers (seeFigure 25). Secondary-sideearthing must be effected atonly one core-balance currenttransformer. The displacementvoltage is to be utilized addi-tionally as enable criterion.The load resistor takes theform either of primary or ofsecondary resistor with neutraltransformer. In the case ofseveral generators connectedto the busbar, again only onegenerator will be earthed viathe resistor.

Unit connection with iso-lated star point

This configuration of unit con-nection is a variant to be rec-ommended (see Figure 26).Earth-fault detection is ef-fected by means of the dis-placement voltage. In order toprevent unwanted operation inthe event of earth faults in thesystem, a load resistor mustbe provided at the broken deltawinding. Depending on theplant, a voltage transformerwith a high power (VA) may infact be sufficient. If not, anearthing transformer should beemployed. The available mea-suring winding can be used forthe purpose of voltage mea-surement.Rotor earth-fault protectioncan be implemented with theunassigned earth-fault currentinput. The 7XR61 coupling unitmust be used for this purpose.


Figure 26

Figure 25

Unit connection with neutraltransformer

With this system configura-tion, disturbance voltage re-duction and damping in theevent of earth faults in thegenerator area are effected bya load resistor connected togenerator neutral point. Themaximum earth-fault current islimited to approximately 10 A.Configuration can take theform of a primary or secondaryresistor with neutral trans-former. In order to avoid lowsecondary resistance, thetransformation ratio of theneutral transformer should below. The higher secondaryvoltage can be reduced bymeans of a voltage divider.Electrically, the circuit is identi-cal to the above configuration(Figure 26).

Connection withlow-voltage generators

As is generally known, thelow-voltage system is solidlyearthed, so that the generatorneutral point is connected toearth (see Figure 28). With thisconfiguration, there is the riskthat, as a result of the 3rd har-monics forming a zerophase-sequence system, cir-culating currents will flow viathe N-conductor. This must belimited by the generator or sys-tem configuration (reactor).Otherwise, connection corre-sponds to the customary stan-dard. In the case of residualcurrent transformer design, itis to be ensured that the ther-mal current limit (1s) of the IEE

input is restricted to 300 A.



Connections/Typical application

Figure 28

Figure 27

Voltage transformer inopen delta connection(V-connection)

Protection can also be readilyimplemented on voltage trans-formers in open delta-connec-tion. Fig. 29 shows the con-nection involved. If necessary,the operational measured val-ues for the phase-to-earth volt-ages can be slightly asymmet-rical. If this is undesirable, theneutral point (R16) can be con-nected to earth via a capacitor.In the case of open delta-con-nection, it is not possible tocalculate the displacementvoltage from the secondaryvoltages. It must be passed tothe protection device along adifferent path (for example,voltage transformer at the gen-erator neutral point or from theearthing transformer).

Connection with two cur-rent transformers

This configuration is to befound in older systems with in-sulated or high-resistance starpoint. This connection is illus-trated in Fig. 30 opposite. Inthe protection unit, the sec-ondary currents are repre-sented correctly and, in addi-tion, the positive and the nega-tive phase-sequence systemare correctly calculated. Limitsof application occur in the caseof low-resistance and solidearthing.
