1. Application

RET670 provides fast and selectiveprotection, monitoring and control for two-and three-winding transformers,autotransformers, generator-transformer unitsand shunt reactors. The transformer IED isdesigned to operate correctly over a widefrequency range in order to accommodatepower system frequency variations duringdisturbances and generator start-up and shut-down.

A very fast differential protection function,with automatic CT ratio matching and vectorgroup compensation, makes this IED theideal solution even for the most demandingapplications. RET670 has very lowrequirements on the main CTs, nointerposing CTs are required. It is suitable fordifferential applications with multi-breakerarrangements with up to six restraint CTinputs. The differential protection function isprovided with 2nd harmonic and wave-blockrestraint features to avoid tripping formagnetizing inrush, and 5th harmonicrestraint to avoid tripping for overexcitation.

The differential function offers a highsensitivity for low-level internal faults.RET670 unique and innovative sensitivedifferential protection feature, based on well-known theory of symmetrical componentsprovide best possible coverage for windinginternal turn-to-turn faults.

Low impedance restricted earth-faultprotection functions are available ascomplimentary sensitive and fast mainprotection against winding earth faults. Thisfunction includes a directional zero-sequencecurrent criterion for additional security.

Additionally a high impedance differentialfunction is available. It can be used asrestricted earth fault or, as three functions areincluded, also as differential protection onautotransformers, as differential protectionfor a tertiary connected reactor, as T-differential protection for the transformer

feeder in a mesh-corner or ring arrangement,as tertiary bus protection and so on.

Tripping from Pressure relief / Buchholz andtemperature devices can be done through thetransformer IED where pulsing, lock-outcontact output and so on, is performed. Thebinary inputs are heavily stabilized againstdisturbance to prevent incorrect operations atfor example, dc system capacitive dischargesor dc earth faults.

Distance protection functionality for phase-to-phase and/or phase-to-earth faults is availableas back-up protection for faults within thetransformer and in the connected powersystem.

Versatile phase, earth, positive and zerosequence overcurrent functions, which canoptionally be made directional and/or voltagecontrolled, provide further alternative backupprotection. Thermal overload with two time-constants, volts per hertz, over/under voltageand over/under frequency protectionfunctions are also available.

Built-in disturbance and event recorderprovides valuable data to the user aboutstatus and operation for post-faultdisturbance analysis.

Breaker failure protection for eachtransformer breaker allows high speed back-up tripping of surrounding breakers.

The transformer IED can also be providedwith a full control and interlockingfunctionality including Synchrocheck functionto allow integration of the main and/or alocal back-up control.

The advanced logic capability, where userlogic is prepared with a graphical tool, allowsspecial applications such as automaticopening of disconnectors in multi-breakerarrangements, closing of breaker rings, loadtransfer logic and so on. The graphical

The setting facilities cover for applications ofthe differential protection to all types ofpower transformers and autotransformerswith or without load tap changer as well asfor shunt reactors or and local feeders withinthe station. An adaptive stabilizing feature isincluded for heavy through-faults. Byintroducing the load tap changer position, thedifferential protection pick-up can be set tooptimum sensitivity thus covering internalfaults with low fault level.

Stabilization is included for inrush currentsrespectively for overexcitation condition.Adaptive stabilization is also included forsystem recovery inrush and CT saturation forexternal faults. A fast high set unrestraineddifferential current protection is included forvery high speed tripping at high internal faultcurrents.

Innovative sensitive differential protectionfeature, based on the theory of symmetricalcomponents, offers best possible coverage forpower transformer windings turn-to-turnfaults.

1Ph High impedance differentialprotection HZPDIF

The 1Ph High impedance differentialprotection HZPDIF function can be usedwhen the involved CT cores have the sameturn ratio and similar magnetizingcharacteristic. It utilizes an externalsummation of the phases and neutral currentand a series resistor and a voltage dependentresistor externally to the IED.

Restricted earth fault protection (PDIF,87N)

Restricted earth-fault protection, lowimpedance function (REFPDIF) can be usedon all directly or low impedance earthedwindings. REFPDIF function can providehigher sensitivity (down to 5%) and higherspeed as it measures individually on eachwinding and thus do not need inrushstabilization.

The low impedance function is a percentagebiased function with an additional zerosequence current directional comparisoncriteria. This gives excellent sensitivity andstability for through faults. The functionallows use of different CT ratios andmagnetizing characteristics on the phase andneutral CT cores and mixing with otherfunctions and protection IEDs on the samecores.

Impedance protection

Distance measuring zone, quadrilateralcharacteristic ZMQPDIS, ZMQAPDIS

The line distance protection is a four zonefull scheme protection with three fault loopsfor phase-to-phase faults and three faultloops for phase-to-earth fault for each of theindependent zones. Individual settings foreach zone in resistive and reactive reachgives flexibility for use as back-up protectionfor transformer connected to overhead linesand cables of different types and lengths.

ZMQPDIS together with Phase selection withload encroachment FDPSPDIS hasfunctionality for load encroachment, whichincreases the possibility to detect highresistive faults on heavily loaded lines.

The distance protection zones can operateindependently of each other in directional(forward or reverse) or non-directional mode.

Full-scheme distance measuring, Mhocharacteristic ZMHPDIS

The numerical mho line distance protection isafour zone full scheme protection for back-updetection of short circuit and earth faults. Thefour zones have fully independent measuringand settings, which gives high flexibility forall types of lines.

The function can be used as underimpedance back-up protection fortransformers and generators.

Phase selection, quadrilateralcharacteristic with fixed angle FDPSPDIS

The operation of transmission networkstoday is in many cases close to the stability

limit. Due to environmental considerations,the rate of expansion and reinforcement ofthe power system is reduced, for example,difficulties to get permission to build newpower lines. The ability to accurately andreliably classify the different types of fault, sothat single pole tripping and autoreclosingcan be used plays an important role in thismatter. Phase selection, quadrilateralcharacteristic with fixed angle FDPSPDIS isdesigned to accurately select the proper faultloop in the distance function dependent onthe fault type.

The heavy load transfer that is common inmany transmission networks may make faultresistance coverage difficult to achieve.Therefore, FDPSPDIS has a built-in algorithmfor load encroachment, which gives thepossibility to enlarge the resistive setting ofboth the phase selection and the measuringzones without interfering with the load.

The extensive output signals from the phaseselection gives also important informationabout faulty phase(s), which can be used forfault analysis.

Full-scheme distance protection,quadrilateral for earth faults ZMMPDIS,ZMMAPDIS

The distance protection is a four zoneprotection with three fault loops for phase-to-earth fault for each of the independent zones.Individual settings for each zone resistive andreactive reach give flexibility for use onoverhead lines and cables of different typesand lengths.

The Full-scheme distance protection,quadrilateral for earth faults functionsZMMDPIS and ZMMAPDIS have functionalityfor load encroachment, which increases thepossibility to detect high resistive faults onheavily loaded lines .

The independent measurement of impedancefor each fault loop together with a sensitiveand reliable built in phase selection makesthe function suitable in applications withsingle phase auto-reclosing.


14 ABB

The distance protection zones can operate,independent of each other, in directional(forward or reverse) or non-directional mode.This makes them suitable, together withdifferent communication schemes, for theprotection of power lines and cables incomplex network configurations, such asparallel lines, multi-terminal lines.

Directional impedance element for Mhocharacteristic ZDMRDIR

The phase-to-earth impedance elements canbe optionally supervised by a phaseunselective directional function (phaseunselective, because it is based onsymmetrical components).

Faulty phase identification with loadencroachment FMPSPDIS

The operation of transmission networkstoday is in many cases close to the stabilitylimit. Due to environmental considerationsthe rate of expansion and reinforcement ofthe power system is reduced, for exampledifficulties to get permission to build newpower lines. The ability to accurate andreliable classifying the different types of faultso that single phase tripping andautoreclosing can be used plays an importantroll in this matter.

The phase selection function is design toaccurate select the proper fault loop in thedistance function dependent on the fault type.

The heavy load transfer that is common inmany transmission networks may in somecases interfere with the distance protectionzone reach and cause unwanted operation.Therefore the function has a built inalgorithm for load encroachment, which givesthe possibility to enlarge the resistive settingof the measuring zones without interferingwith the load.

The output signals from the phase selectionfunction produce important informationabout faulty phase(s), which can be used forfault analysis as well.

Power swing detection ZMRPSB

Power swings may occur after disconnectionof heavy loads or trip of big generation plants.

Power swing detection function (ZMRPSB) isused to detect power swings and initiateblock of selected distance protection zones.Occurrence of earth-fault currents during apower swing can block ZMRPSB function toallow fault clearance.

Power swing logic ZMRPSL

Additional logic is available to secure trippingfor faults during power swings and preventtripping at power swings started by a fault inthe network.

In isolated networks or in networks withhigh impedance earthing, the earth faultcurrent is significantly smaller than the shortcircuit currents. In addition to this, themagnitude of the fault current is almostindependent on the fault location in thenetwork. The protection can be selected touse either the residual current or residualpower component 3U0·3I0·cos j, foroperating quantity with maintained shortcircuit capacity. There is also available onenondirectional 3I0 step and one 3U0overvoltage tripping step.

Thermal overload protection, two timeconstant TRPTTR

If the temperature of a power transformer/generator reaches very high values the

equipment might be damaged. The insulationwithin the transformer/generator will haveforced ageing. As a consequence of this therisk of internal phase-to-phase or phase-to-earth faults will increase. High temperaturewill degrade the quality of the transformer/generator oil.

The thermal overload protection estimatesthe internal heat content of the transformer/generator (temperature) continuously. Thisestimation is made by using a thermal modelof the transformer/generator with two timeconstants, which is based on currentmeasurement.

Two warning levels are available. Thisenables actions in the power system to bedone before dangerous temperatures arereached. If the temperature continues toincrease to the trip value, the protectioninitiates trip of the protected transformer/generator.

Breaker failure protection CCRBRF

Breaker failure protection (CCRBRF) ensuresfast back-up tripping of surrounding breakersin case of own breaker failure to open.CCRBRF can be current based, contact based,or adaptive combination between these twoprinciples.

A current check with extremely short resettime is used as check criteria to achieve ahigh security against unnecessary operation.

A contact check criteria can be used wherethe fault current through the breaker is small.

CCRBRF can be single- or three-phaseinitiated to allow use with single phasetripping applications. For the three-phaseversion of CCRBRF the current criteria can beset to operate only if two out of four forexample, two phases or one phase plus theresidual current start. This gives a highersecurity to the back-up trip command.

CCRBRF function can be programmed to givea single- or three-phase re-trip of the ownbreaker to avoid unnecessary tripping ofsurrounding breakers at an incorrectinitiation due to mistakes during testing.


16 ABB

Pole discordance protection CCRPLD

Single pole operated circuit breakers can dueto electrical or mechanical failures end upwith the different poles in different positions(close-open). This can cause negative andzero sequence currents which gives thermalstress on rotating machines and can causeunwanted operation of zero sequence ornegative sequence current functions.

Normally the own breaker is tripped tocorrect such a situation. If the situationpersists the surrounding breaker should betripped to clear the unsymmetrical loadsituation.

The Polediscordance protection functionCCRPLD operates based on information fromauxiliary contacts of the circuit breaker forthe three phases with additional criteria fromunsymmetrical phase current when required.

Directional over/underpower protectionGOPPDOP/GUPPDUP

The directional over-/under-power protection(GOPPDOP/GUPPDUP) can be usedwherever a high/low active, reactive orapparent power protection or alarming isrequired. The functions can alternatively beused to check the direction of active orreactive power flow in the power system.There are number of applications where suchfunctionality is needed. Some of them are:

• detection of reversed active power flow• detection of high reactive power flow

Each function has two steps with definitetime delay. Reset times for every step can beset as well.

Broken conductor check BRCPTOC

The main purpose of the function Brokenconductor check (BRCPTOC) is the detectionof broken conductors on protected powerlines and cables (series faults). Detection canbe used to give alarm only or trip the linebreaker.

Voltage protection

Two step undervoltage protectionUV2PTUV

Undervoltages can occur in the power systemduring faults or abnormal conditions. Twostep undervoltage protection (UV2PTUV)function can be used to open circuit breakersto prepare for system restoration at poweroutages or as long-time delayed back-up toprimary protection.

ROV2PTOV has two voltage steps, each withinverse or definite time delayed.


ABB 17

Overexcitation protection OEXPVPH

When the laminated core of a powertransformer or generator is subjected to amagnetic flux density beyond its designlimits, stray flux will flow into non-laminatedcomponents not designed to carry flux andcause eddy currents to flow. The eddycurrents can cause excessive heating andsevere damage to insulation and adjacentparts in a relatively short time. Overexcitationprotection OEXPVPH has settable inverseoperating curve and independent alarm stage.

Voltage differential protection VDCPTOV

Multipurpose protection

General current and voltage protectionCVGAPC

The protection module is recommended as ageneral backup protection with manypossible application areas due to its flexiblemeasuring and setting facilities.

The built-in overcurrent protection featurehas two settable current levels. Both of themcan be used either with definite time orinverse time characteristic. The overcurrentprotection steps can be made directional withselectable voltage polarizing quantity.Additionally they can be voltage and/orcurrent controlled/restrained. 2nd harmonicrestraining facility is available as well. At toolow polarizing voltage the overcurrent featurecan be either blocked, made non directionalor ordered to use voltage memory inaccordance with a parameter setting.

Additionally two overvoltage and twoundervoltage steps, either with definite timeor inverse time characteristic, are availablewithin each function.


18 ABB

The general function suits applications withunderimpedance and voltage controlledovercurrent solutions. The general functioncan also be utilized for generator transformerprotection applications where positive,negative or zero sequence components ofcurrent and voltage quantities are typicallyrequired.

Secondary system supervision

Current circuit supervision CCSRDIF

Open or short circuited current transformercores can cause unwanted operation of manyprotection functions such as differential,earth-fault current and negative-sequencecurrent functions.

It must be remembered that a blocking ofprotection functions at an occurrence of openCT circuit will mean that the situation willremain and extremely high voltages willstress the secondary circuit.

Current circuit supervision (CCSRDIF)compares the residual current from a threephase set of current transformer cores withthe neutral point current on a separate inputtaken from another set of cores on thecurrent transformer.

A detection of a difference indicates a fault inthe circuit and is used as alarm or to blockprotection functions expected to giveunwanted tripping.

Fuse failure supervision (RFUF)

Failures in the secondary circuits of thevoltage transformer can cause unwantedoperation of distance protection,undervoltage protection, neutral point voltageprotection, energizing function (synchronismcheck) etc. The fuse failure supervisionfunction prevents such unwanted operations.

There are three methods to detect fuse failures.

The method based on detection of zerosequence voltage without any zero sequencecurrent. This is a useful principle in a directlyearthed system and can detect one or twophase fuse failures.

The method based on detection of negativesequence voltage without any negativesequence current. This is a useful principle ina non-directly earthed system and can detectone or two phase fuse failures.

The method based on detection of du/dt-di/dt where a change of the voltage is comparedto a change in the current. Only voltagechanges means a voltage transformer fault.This principle can detect one, two or threephase fuse failures.

Control

Synchronizing, synchrocheck andenergizing check SESRSYN

The Synchronizing function allows closing ofasynchronous networks at the correctmoment including the breaker closing time.The systems can thus be reconnected after anautoreclose or manual closing, whichimproves the network stability.

Synchrocheck, energizing check (SESRSYN)function checks that the voltages on bothsides of the circuit breaker are insynchronism, or with at least one side deadto ensure that closing can be done safely.

SESRSYN function includes a built-in voltageselection scheme for double bus and 1½breaker or ring busbar arrangements.

Manual closing as well as automatic reclosingcan be checked by the function and can havedifferent settings.

For systems which are running asynchronousa synchronizing function is provided. Themain purpose of the synchronizing functionis to provide controlled closing of circuitbreakers when two asynchronous systems aregoing to be connected. It is used for slipfrequencies that are larger than those forsynchrocheck and lower than a set maximumlevel for the synchronizing function.

Apparatus control APC

The apparatus control is a function forcontrol and supervision of circuit breakers,disconnectors and earthing switches within abay. Permission to operate is given after


ABB 19

evaluation of conditions from other functionssuch as interlocking, synchrocheck, operatorplace selection and external or internalblockings.

Features in the apparatus control function:

• Select-Execute principle to give highreliability

• Selection function to prevent simultaneousoperation

• Selection and supervision of operator place• Command supervision• Block/deblock of operation• Block/deblock of updating of position

indications• Substitution of position indications• Overriding of interlocking functions• Overriding of synchrocheck• Operation counter• Suppression of Mid position

Two types of command models can be used:

• Direct with normal security• SBO (Select-Before-Operate) with enhanced

security

Normal security means that only thecommand is evaluated and the resultingposition is not supervised. Enhanced securitymeans that the command is evaluated with anadditional supervision of the status value ofthe control object. The command securitywith enhanced security is always terminatedby a CommandTermination service primitive.

Control operation can be performed from thelocal HMI under authority control if so defined.

Voltage control TR1ATCC, TR8ATCC,TCMYLTC and TCLYLTC

The voltage control functions, Automaticvoltage control for tap changer, single control(TR1ATCC,), Automatic voltage control fortap changer, parallel control (TR8ATCC,) andTap changer control and supervision, 6binary inputs (TCMYLTC,) as well as Tapchanger control and supervision, 32 binaryinputs TCLYLTC are used for control ofpower transformers with a motor driven loadtap changer. The function provides automatic

regulation of the voltage on the secondaryside of transformers or alternatively on a loadpoint further out in the network.

Control of a single transformer, as well ascontrol of up to eight transformers in parallelis possible. For parallel control of powertransformers, three alternative methods areavailable, the master-follower method, thecirculating current method and the reversereactance method. The two former methodsrequire exchange of information between theparallel transformers and this is provided forwithin IEC61850-8-1.

Voltage control includes many extra featuressuch as possibility of to avoid simultaneoustapping of parallel transformers, hot stand byregulation of a transformer in a group whichregulates it to a correct tap position eventhough the LV CB is open, compensation fora possible capacitor bank on the LV side bayof a transformer, extensive tap changermonitoring including contact wear andhunting detection, monitoring of the powerflow in the transformer so that for example,the voltage control can be blocked if thepower reverses etc.

Logic rotating switch for functionselection and LHMI presentation SLGGIO

The logic rotating switch for functionselection and LHMI presentation function(SLGGIO) (or the selector switch functionblock) is used to get a selector switchfunctionality similar with the one provided bya hardware selector switch. Hardwareselector switches are used extensively byutilities, in order to have different functionsoperating on pre-set values. Hardwareswitches are however sources formaintenance issues, lower system reliabilityand extended purchase portfolio. The virtualselector switches eliminate all these problems.

Selector mini switch VSGGIO

Selector mini switch (VSGGIO) functionblock is a multipurpose function used in theconfiguration tool in PCM600 for a variety ofapplications, as a general purpose switch.


20 ABB

Single point generic control 8 signalsSPC8GGIO

The Single point generic control 8 signals(SPC8GGIO) function block is a collection of8 single point commands, designed to bringin commands from REMOTE (SCADA) tothose parts of the logic configuration that donot need complicated function blocks thathave the capability to receive commands (forexample, SCSWI). In this way, simplecommands can be sent directly to the IEDoutputs, without confirmation. Confirmation(status) of the result of the commands issupposed to be achieved by other means,such as binary inputs and SPGGIO functionblocks.

Scheme communication

Scheme communication logic for residualovercurrent protection ECPSCH

To achieve fast fault clearance of earth faultson the part of the line not covered by theinstantaneous step of the residual overcurrentprotection, the directional residualovercurrent protection can be supported witha logic that uses communication channels.

In the directional scheme, information of thefault current direction must be transmitted tothe other line end. With directionalcomparison, a short operates time of theprotection including a channel transmissiontime, can be achieved. This short operatetime enables rapid autoreclosing functionafter the fault clearance.

The communication logic module fordirectional residual current protectionenables blocking as well as permissive under/overreaching schemes. The logic can also besupported by additional logic for weak-endinfeed and current reversal, included inCurrent reversal and weak-end infeed logicfor residual overcurrent protection Currentreversal and weak-end infeed logic for

residual overcurrent protection (ECRWPSCH)function.

Current reversal and weak-end infeed logicfor residual overcurrent protectionECRWPSCH

The Current reversal and weak-end infeedlogic for residual overcurrent protectionECRWPSCH is a supplement to Schemecommunication logic for residual overcurrentprotection ECPSCH.

To achieve fast fault clearing for all earthfaults on the line, the directional earth-faultprotection function can be supported withlogic that uses communication channels.

The 670 series IEDs have for this reasonavailable additions to scheme communicationlogic.

If parallel lines are connected to commonbusbars at both terminals, overreachingpermissive communication schemes can tripunselectively due to fault current reversal.This unwanted tripping affects the healthyline when a fault is cleared on the other line.This lack of security can result in a total lossof interconnection between the two buses. Toavoid this type of disturbance, a fault currentreversal logic (transient blocking logic) canbe used.

Permissive communication schemes forresidual overcurrent protection, can basicallyoperate only when the protection in theremote terminal can detect the fault. Thedetection requires a sufficient minimumresidual fault current, out from this terminal.The fault current can be too low due to anopened breaker or high positive and/or zerosequence source impedance behind thisterminal. To overcome these conditions,weak end infeed (WEI) echo logic is used.

Disturbance report DRPRDRE

Complete and reliable information aboutdisturbances in the primary and/or in thesecondary system together with continuousevent-logging is accomplished by thedisturbance report functionality.

Disturbance report DRPRDRE, alwaysincluded in the IED, acquires sampled data ofall selected analog input and binary signalsconnected to the function block that is,maximum 40 analog and 96 binary signals.

Disturbance report functionality is a commonname for several functions:

• Event list• Indications• Event recorder• Trip value recorder• Disturbance recorder

Disturbance report function is characterizedby great flexibility regarding configuration,starting conditions, recording times and largestorage capacity.

A disturbance is defined as an activation ofan input in the AxRADR or BxRBDR functionblocks, which is set to trigger the disturbancerecorder. All signals from start of pre-fault

time to the end of post-fault time will beincluded in the recording.

Every disturbance report recording is savedin the IED in the standard Comtrade format.The same applies to all events, which arecontinuously saved in a ring-buffer. The localHMI is used to get information about therecordings, but the disturbance report filesmay be uploaded to PCM600 and furtheranalysis using the disturbance handling tool.

Itfacilitates understanding system behavior andrelated primary and secondary equipmentduring and after a disturbance. Recordedinformation is used for different purposes inthe short perspective (for example correctiveactions) and long perspective (for exampleFunctional Analysis).
