  • 1. ApplicationREL670 is used for the protection, control andmonitoring of overhead lines and cables in solidlyearthed networks. The IED can be used up to thehigh voltage levels. It is suitable for the protectionof heavily loaded lines and multi-terminal lineswhere the requirement for tripping is one-, two-,and/or three-phase. The IED is also suitable asback-up protection of power transformers,reactors and so on.The full scheme distance protection providesprotection of power lines with high sensitivity andlow requirement on remote end communication.The five zones have fully independent measuringand setting which gives high flexibility for all typesof lines.The modern technical solution offers fastoperating time of typically 1.5 cycles.The REL670 also includes an alternative for usedon not solidly earthed networks. It includes PhasePreference Logic to select and trip only one lineat cross-country faults.The autoreclose for single-, two-, and/or three-phase reclose includes priority features for multi-breaker arrangements. It co-operates with thesynchrocheck function with high-speed ordelayed reclosing.A high impedance differential protection can beused to protect T-feeders or line reactors.High set instantaneous phase and earthovercurrent, four step directional or non-directional delayed phase and earth overcurrent,sensitive earth fault for not direct earthedsystems, thermal overload and two step underand overvoltage protection are examples of theavailable functions allowing the user to fulfill anyapplication requirement.The distance phase and earth fault protection cancommunicate with remote end in anyteleprotection communication scheme. With theincluded remote communication, following theIEEE C37.94 standard, 6 x 32 channels forintertrip and binary signals are available perLDCM communication module in thecommunication between the IEDs.

    The IED can also be provided with full bay controland interlocking functionality including co-operation with the synchrocheck function to allowintegration of the main or back-up control.Out of Step function is available to separatepower system sections close to electrical centreat occurring out of step.The advanced logic capability, where the userlogic is prepared with a graphical tool, allowsspecial applications such as automatic opening ofdisconnectors in multi-breaker arrangements,closing of breaker rings, load transfer logics andso on. The graphical configuration tool with delaymode, ensures simple and fast testing andcommissioning.Disturbance recording and fault locator areavailable to allow independent post-fault analysisafter primary disturbances.Serial data communication is via opticalconnections to ensure immunity againstdisturbances.The wide application flexibility makes this productan excellent choice for both new installations andthe refurbishment of existing installations.Five packages has been defined for followingapplications:

    Single-breaker (double or single bus) withthree phase tripping for high ohmic andresonance earthed systems (A21)

    Single-breaker (double or single bus) withthree phase tripping (A31)

    Single-breaker (double or single bus) withsingle phase tripping (A32)

    Multi-breaker (one-and a half or ring) withthree phase tripping (B31)

    Multi-breaker (one-and a half or ring) withsingle phase tripping (B32)

    Optional functions are not configured but amaximum configuration with all optional functionsare available as template in the graphicalconfiguration tool. Analog and tripping I/O hasbeen pre-defined for basic use.Add binary I/O as required for the applicationwhen ordering. Other signals need to be appliedas required for each application.

    4. Impedance protectionDistance measuring zone, quadrilateralcharacteristic ZMQPDIS, ZMQAPDIS (21)The line distance protection is a five zone fullscheme protection with three fault loops forphase-to-phase faults and three fault loops forphase-to-earth faults for each of the independentzones. Individual settings for each zone inresistive and reactive reach gives flexibility for useas back-up protection for transformer connectedto overhead lines and cables of different typesand lengths.ZMQPDIS together with Phase selection with loadencroachment FDPSPDIS has functionality forload encroachment, which increases thepossibility to detect high resistive faults on heavilyloaded lines.The independent measurement of impedance foreach fault loop together with a sensitive andreliable built-in phase selection makes thefunction suitable in applications with single-phaseautoreclosing.Built-in adaptive load compensation algorithmprevents overreaching of zone 1 at load exportingend at phase-to-earth faults on heavily loadedpower lines.The distance protection zones can operateindependently of each other in directional (forwardor reverse) or non-directional mode.

Due toenvironmental considerations, the rate of

  • expansion and reinforcement of the power systemis reduced, for example, difficulties to getpermission to build new power lines. The ability toaccurately and reliably classify the different typesof fault, so that single pole tripping andautoreclosing can be used plays an important rolein this matter.Phase selection, quadrilateralcharacteristic with fixed angle FDPSPDIS isdesigned to accurately select the proper faultloop in the distance function dependent on thefault type.The heavy load transfer that is common in manytransmission networks may make fault resistancecoverage difficult to achieve. Therefore,FDPSPDIS has a built-in algorithm for loadencroachment, which gives the possibility toenlarge the resistive setting of both the phaseselection and the measuring zones withoutinterfering with the load.The extensive output signals from the phaseselection gives also important information aboutfaulty phase(s), which can be used for faultanalysis.A current-based phase selection is also included.The measuring elements continuously measurethree phase currents and the residual currentand, compare them with the set values.Power swing detection ZMRPSBPower swings may occur after disconnection ofheavy loads or trip of big generation plants.Power swing detection function (ZMRPSB) isused to detect power swings and initiate block ofselected distance protection zones. Occurrenceof earth-fault currents during a power swinginhibits the ZMRPSB function to allow faultclearance.Power swing logic ZMRPSLAdditional logic is available to secure tripping forfaults during power swings and prevent tripping atpower swings started by a fault in the network.Pole slip protection PSPPPAMSudden events in an electrical power system suchas large changes in load, fault occurrence or faultclearance, can cause power oscillations referredto as power swings. In a non-recoverablesituation, the power swings become so severethat the synchronism is lost, a condition referred

    to as pole slipping. The main purpose of the poleslip protection (PSPPPAM) is to detect, evaluate,and take the required action for pole slippingoccurrences in the power system. The electricalsystem parts swinging to each other can beseparated with the line/s closest to the centre ofthe power swing allowing the two systems to bestable as separated islands.Automatic switch onto fault logic, voltage andcurrent based ZCVPSOFAutomatic switch onto fault logic (ZCVPSOF) is afunction that gives an instantaneous trip atclosing of breaker onto a fault. A dead linedetection check is provided to activate thefunction when the line is dead.Phase preference logic PPLPHIZThe optional phase preference logic main purposeis to provide a selective tripping for cross-countryfaults in isolated or high impedance-earthednetworks.

    5. Current protectionInstantaneous phase overcurrent protectionPHPIOCThe instantaneous three phase overcurrentfunction has a low transient overreach and shorttripping time to allow use as a high set short-circuit protection function.Four step phase overcurrent protection OC4PTOCThe four step phase overcurrent protectionfunction OC4PTOC has an inverse or definite timedelay independent for step 1 and 4 separately.Step 2 and 3 are always definite time delayed.All IEC and ANSI inverse time characteristics areavailable together with an optional user definedtime characteristic.The directional function is voltage polarized withmemory. The function can be set to be directionalor non-directional independently for each of thesteps.A 2nd harmonic blocking can be set individuallyfor each step.Instantaneous residual overcurrent protectionEFPIOCThe Instantaneous residual overcurrent protectionEFPIOC has a low transient overreach and short

EFPIOC can beconfigured to measure the residual current fromthe three-phase current inputs or the current froma separate current input. EFPIOC can be blockedby activating the input BLOCK.Four step residual overcurrent protection, zerosequence and negative sequence directionEF4PTOCThe four step residual overcurrent protectionEF4PTOC has an inverse or definite time delayindependent for each step separately.All IEC and ANSI time-delayed characteristics areavailable together with an optional user definedcharacteristic.EF4PTOC can be set directional or non-directional independently for each of the steps.IDir, UPol and IPol can be independently selectedto be either zero sequence or negative sequence.Second harmonic blocking can be set individuallyfor each step.EF4PTOC can be used as main protection forphase-to-earth faults.EF4PTOC can also be used to provide a systemback-up for example, in the case of the primaryprotection being out of service due tocommunication or voltage transformer circuitfailure.Directional operation can be combined togetherwith corresponding communication logic inpermissive or blocking teleprotection scheme.Current reversal and weak-end infeed functionalityare available as well.EF4PTOC can be configured to measure theresidual current from the three-phase currentinputs or the current from a separate current input.Four step negative sequence overcurrentprotection NS4PTOCFour step negative sequence overcurrentprotection (NS4PTOC) has an inverse or definitetime delay independent for each step separately.

    All IEC and ANSI time delayed characteristics areavailable together with an optional user definedcharacteristic.The directional function is voltage polarized ordual polarized.NS4PTOC can be set directional or non-directional independently for each of the steps.NS4PTOC can be used as main protection forunsymmetrical fault; phase-phase short circuits,phase-phase-earth short circuits and single phaseearth faults.NS4PTOC can also be used to provide a systemback-up for example, in the case of the primaryprotection being out of service due tocommunication or voltage transformer circuitfailure.Directional operation can be combined togetherwith corresponding communication logic inpermissive or blocking teleprotection scheme.The same logic as for directional zero sequencecurrent can be used. Current reversal and weak-end infeed functionality are available.Sensitive directional residual overcurrent andpower protection SDEPSDEIn isolated networks or in networks with highimpedance earthing, the earth fault current issignificantly smaller than the short circuit currents.In addition to this, the magnitude of the faultcurrent is almost independent on the fault locationin the network. The protection can be selected touse either the residual current or residual powercomponent 3U03I0cos j, for operating quantitywith maintained short circuit capacity. There isalso available one nondirectional 3I0 step and one3U0 overvoltage tripping step.No specific sensitive current input isneeded.SDEPSDE can be set as low 0.25% ofIBase.Thermal overload protection, one time constantLPTTRThe increasing utilizing of the power systemcloser to the thermal limits has generated a needof a thermal overload protection also for powerlines.A thermal overload will often not be detected byother protection functions and the introduction of

  • the thermal overload protection can allow theprotected circuit to operate closer to the thermallimits.The three-phase current measuring protectionhas an I2t characteristic with settable timeconstant and a thermal memory..An alarm level gives early warning to allowoperators to take action well before the line istripped.Breaker failure protection CCRBRFBreaker failure protection (CCRBRF) ensures fastback-up tripping of surrounding breakers in casethe own breaker fails to open. CCRBRF can becurrent based, contact based, or an adaptivecombination of these two conditions.Current check with extremely short reset time isused as check criterion to achieve high securityagainst unnecessary operation.Contact check criteria can be used where thefault current through the breaker is small.CCRBRF can be single- or three-phase initiatedto allow use with single phase trippingapplications. For the three-phase version ofCCRBRF the current criteria can be set to operateonly if two out of four for example, two phases orone phase plus the residual current start. Thisgives a higher security to the back-up tripcommand.CCRBRF function can be programmed to give asingle- or three-phase re-trip of the own breakerto avoid unnecessary tripping of surroundingbreakers at an incorrect initiation due to mistakesduring testing.Stub protection STBPTOCWhen a power line is taken out of service formaintenance and the line disconnector is openedin multi-breaker arrangements the voltagetransformers will mostly be outside on thedisconnected part. The primary line distanceprotection will thus not be able to operate andmust be blocked.The stub protection STBPTOC covers the zonebetween the current transformers and the opendisconnector. The three-phase instantaneousovercurrent function is released from a normally

    open, NO (b) auxiliary contact on the linedisconnector.Pole discordance protection CCRPLDAn open phase can cause negative and zerosequence currents which cause thermal stress onrotating machines and can cause unwantedoperation of zero sequence or negative sequencecurrent functions.Normally the own breaker is tripped to correctsuch a situation. If the situation persists thesurrounding breakers should be tripped to clearthe unsymmetrical load situation.The Polediscordance protection function CCRPLDoperates based on information from auxiliarycontacts of the circuit breaker for the threephases with additional criteria from unsymmetricalphase currents when required.Directional over/underpower protectionGOPPDOP/GUPPDUPThe directional over-/under-power protectionGOPPDOP/GUPPDUP can be used wherever ahigh/low active, reactive or apparent powerprotection or alarming is required. The functionscan alternatively be used to check the direction ofactive or reactive power flow in the power system.There are a 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 definite timedelay. Reset times for both steps can be set aswell.Broken conductor check BRCPTOCThe main purpose of the function Brokenconductor check (BRCPTOC) is the detection ofbroken conductors on protected power lines andcables (series faults). Detection can be used togive alarm only or trip the line breaker.

  • system restoration at power outages or as long-time delayed back-up to primary protection.UV2PTUV has two voltage steps, each withinverse or definite time delay.Two step overvoltage protection OV2PTOVOvervoltages may occur in the power systemduring abnormal conditions such as suddenpower loss, tap changer regulating failures, openline ends on long lines etc.Two step overvoltage protection (OV2PTOV)function can be used to detect open line ends,normally then combined with a directional reactiveover-power function to supervise the systemvoltage. When triggered, the function will causean alarm, switch in reactors, or switch outcapacitor banks.OV2PTOV has two voltage steps, each of themwith inverse or definite time delayed.OV2PTOV has an extremely high reset ratio toallow settings close to system service voltage.Two step residual overvoltage protectionROV2PTOVResidual voltages may occur in the power systemduring earth faults.Two step residual overvoltage protectionROV2PTOV function calculates the residualvoltage from the three-phase voltage inputtransformers or measures it from a single voltageinput transformer fed from an open delta orneutral point voltage transformer.ROV2PTOV has two voltage steps, each withinverse or definite time delay.Reset delay ensures operation for intermittentearth faults.Overexcitation protection OEXPVPHWhen the laminated core of a power transformeror generator is subjected to a magnetic fluxdensity beyond its design limits, stray flux will flowinto non-laminated components not designed tocarry flux and cause eddy currents to flow. Theeddy currents can cause excessive heating andsevere damage to insulation and adjacent parts ina relatively short time. The function has settableinverse operating curves and independent alarmstages.

    Voltage differential protection VDCPTOVA voltage differential monitoring function isavailable. It compares the voltages from two threephase sets of voltage transformers and has onesensitive alarm step and one trip step.Loss of voltage check LOVPTUVLoss of voltage check (LOVPTUV) is suitable foruse in networks with an automatic systemrestoration function. LOVPTUV issues a three-pole trip command to the circuit breaker, if allthree phase voltages fall below the set value for atime longer than the set time and the circuitbreaker remains closed.

    7. Frequency protectionUnderfrequency protection SAPTUFUnderfrequency occurs as a result of a lack ofgeneration in the network.Underfrequency protection SAPTUF is used forload shedding systems, remedial action schemes,gas turbine startup and so on.SAPTUF is also provided with undervoltageblocking.The operation is based on positive sequencevoltage measurement and requires two phase-phase or three phase-neutral voltages to beconnected.

    Overfrequency protection SAPTOFOverfrequency protection function SAPTOF isapplicable in all situations, where reliabledetection of high fundamental power systemfrequency is needed.Overfrequency occurs because of sudden loaddrops or shunt faults in the power network.

    8. Multipurpose protectionGeneral current and voltage protection CVGAPCThe General current and voltage protection(CVGAPC) can be utilized as a negative sequencecurrent protection detecting unsymmetricalconditions such as open phase or unsymmetricalfaults.CVGAPC can also be used to improve phaseselection for high resistive earth faults, outside thedistance protection reach, for the transmissionline. Three functions are used, which measuresthe neutral current and each of the three phasevoltages. This will give an independence fromload currents and this phase selection will beused in conjunction with the detection of the earthfault from the directional earth fault protectionfunction.

    9. Secondary system supervisionCurrent circuit supervision CCSRDIFOpen or short circuited current transformer corescan cause unwanted operation of manyprotection functions such as differential, earth-fault current and negative-sequence currentfunctions.

    It must be remembered that a blocking ofprotection functions at an occurrence of open CTcircuit will mean that the situation will remain andextremely high voltages will stress the secondarycircuit.Current circuit supervision (CCSRDIF) comparesthe residual current from a three phase set ofcurrent transformer cores with the neutral pointcurrent on a separate input taken from anotherset of cores on the current transformer.A detection of a difference indicates a fault in thecircuit and is used as alarm or to block protectionfunctions expected to give unwanted tripping.Fuse failure supervision SDDRFUFThe aim of the fuse failure supervision function(SDDRFUF) is to block voltage measuringfunctions at failures in the secondary circuitsbetween the voltage transformer and the IED inorder to avoid unwanted operations thatotherwise might occur.The fuse failure supervision function basically hasthree different algorithms, negative sequence andzero sequence based algorithms and anadditional delta voltage and delta currentalgorithm.The negative sequence detection algorithm isrecommended for IEDs used in isolated or high-impedance earthed networks. It is based on thenegative-sequence measuring quantities, a highvalue of voltage 3U2 without the presence of thenegative-sequence current 3I2.

    The zero sequence detection algorithm isrecommended for IEDs used in directly or lowimpedance earthed networks. It is based on thezero sequence measuring quantities, a high valueof voltage 3U0 without the presence of theresidual current 3I0.

    For better adaptation to system requirements, anoperation mode setting has been introducedwhich makes it possible to select the operatingconditions for negative sequence and zerosequence based function. The selection ofdifferent operation modes makes it possible tochoose different interaction possibilities betweenthe negative sequence and zero sequence basedalgorithm.

  • A criterion based on delta current and deltavoltage measurements can be added to the fusefailure supervision function in order to detect athree phase fuse failure, which in practice is moreassociated with voltage transformer switchingduring station operations.

    10. ControlSynchrocheck, energizing check, andsynchronizing SESRSYNThe Synchronizing function allows closing ofasynchronous networks at the correct momentincluding the breaker closing time, whichimproves the network stability.Synchrocheck, energizing check, andsynchronizing (SESRSYN) function checks thatthe voltages on both sides of the circuit breakerare in synchronism, 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 1 breakeror ring busbar arrangements.Manual closing as well as automatic reclosing canbe checked by the function and can have differentsettings.For systems which are running asynchronous asynchronizing function is provided. The mainpurpose of the synchronizing function is toprovide controlled closing of circuit breakerswhen two asynchronous systems are going to beconnected. It is used for slip frequencies that arelarger than those for synchrocheck and lowerthan a set maximum level for the synchronizingfunction.Autorecloser SMBRRECThe autorecloser SMBRREC function provideshigh-speed and/or delayed auto-reclosing forsingle or multi-breaker applications.Up to five three-phase reclosing attempts can beincluded by parameter setting. The first attemptcan be single-, two and/or three phase for singlephase or multi-phase faults respectively.Multiple autoreclosing functions are provided formulti-breaker arrangements. A priority circuitallows one circuit breaker to close first and the

    second will only close if the fault proved to betransient.Each autoreclosing function can be configured toco-operate with a synchrocheck function.Apparatus control APCThe apparatus control functions are used forcontrol and supervision of circuit breakers,disconnectors and earthing switches within a bay.Permission to operate is given after evaluation ofconditions from other functions such asinterlocking, synchrocheck, operator placeselection and external or internal blockings.Apparatus control features: Select-Execute principle to give high reliability Selection function to prevent simultaneous

    operation 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

    In normal security, the command is processedand the resulting position is not supervised.However with enhanced security, the command isprocessed and the resulting position is supervised.Normal security means that only the command isevaluated and the resulting position is notsupervised. Enhanced security means that thecommand is evaluated with an additionalsupervision of the status value of the controlobject. The command security with enhancedsecurity is always terminated by aCommandTermination service primitive.Control operation can be performed from thelocal HMI under authority control if so defined.

  • InterlockingThe interlocking function blocks the possibility tooperate primary switching devices, for instancewhen a disconnector is under load, in order toprevent material damage and/or accidentalhuman injury.Each apparatus control function has interlockingmodules included for different switchyardarrangements, where each function handlesinterlocking of one bay. The interlocking functionis distributed to each IED and is not dependenton any central function. For the station-wideinterlocking, the IEDs communicate via thesystem-wide interbay bus (IEC 61850-8-1) or byusing hard wired binary inputs/outputs. Theinterlocking conditions depend on the circuitconfiguration and apparatus position status at anygiven time.For easy and safe implementation of theinterlocking function, the IED is delivered withstandardized and tested software interlockingmodules containing logic for the interlockingconditions. The interlocking conditions can bealtered, to meet the customers specificrequirements, by adding configurable logic bymeans of the graphical configuration tool.Logic rotating switch for function selection andLHMI presentation SLGGIOThe logic rotating switch for function selectionand LHMI presentation (SLGGIO) (or the selectorswitch function block) is used to get a selectorswitch functionality similar to the one provided bya hardware selector switch. Hardware selectorswitches are used extensively by utilities, in orderto have different functions operating on pre-setvalues. Hardware switches are however sourcesfor maintenance issues, lower system reliabilityand an extended purchase portfolio. The logicselector switches eliminate all these problems.Selector mini switch VSGGIOThe Selector mini switch VSGGIO function blockis a multipurpose function used for a variety ofapplications, as a general purpose switch.VSGGIO can be controlled from the menu or froma symbol on the single line diagram (SLD) on thelocal HMI.

    IEC 61850 generic communication I/O functionsDPGGIOThe IEC 61850 generic communication I/Ofunctions (DPGGIO) function block is used tosend double indications to other systems orequipment in the substation. It is especially usedin the interlocking and reservation station-widelogics.Single point generic control 8 signals SPC8GGIOThe Single point generic control 8 signals(SPC8GGIO) function block is a collection of 8single point commands, designed to bring incommands from REMOTE (SCADA) to those partsof the logic configuration that do not needextensive command receiving functionality (forexample, SCSWI). In this way, simple commandscan be sent directly to the IED outputs, withoutconfirmation. Confirmation (status) of the result ofthe commands is supposed to be achieved byother means, such as binary inputs and SPGGIOfunction blocks. The commands can be pulsed orsteady.AutomationBits, command function for DNP3.0AUTOBITSAutomationBits function for DNP3 (AUTOBITS) isused within PCM600 to get into the configurationof the commands coming through the DNP3protocol. The AUTOBITS function plays the samerole as functions GOOSEBINRCV (for IEC 61850)and MULTICMDRCV (for LON).Single command, 16 signalsThe IEDs can receive commands either from asubstation automation system or from the localHMI. The command function block has outputsthat can be used, for example, to control highvoltage apparatuses or for other user definedfunctionality.

    11. Scheme communicationScheme communication logic for distance orovercurrent protection ZCPSCHTo achieve instantaneous fault clearance for allline faults, scheme communication logic isprovided. All types of communication schemes forexample, permissive underreaching, permissiveoverreaching, blocking, unblocking, intertrip areavailable.

  • The built-in communication module (LDCM) canbe used for scheme communication signalingwhen included.Phase segregated scheme communication logicfor distance protection ZC1PPSCHCommunication between line ends is used toachieve fault clearance for all faults on a powerline. All possible types of communicationschemes for example, permissive underreach,permissive overreach and blocking schemes areavailable. To manage problems with simultaneousfaults on parallel power lines phase segregatedcommunication is needed. This will then replacethe standard Scheme communication logic fordistance or Overcurrent protection (ZCPSCH) onimportant lines where three communicationchannels (in each subsystem) are available for thedistance protection communication.The main purpose of the Phase segregatedscheme communication logic for distanceprotection (ZC1PPSCH) function is to supplementthe distance protection function such that:

    fast clearance of faults is also achieved atthe line end for which the faults are on thepart of the line not covered by itsunderreaching zone.

    correct phase selection can be maintained tosupport single-pole tripping for faultsoccurring anywhere on the entire length of adouble circuit line.

    To accomplish this, three separatecommunication channels, that is, one per phase,each capable of transmitting a signal in eachdirection is required.ZC1PPSCH can be completed with the currentreversal and WEI logic for phase segregatedcommunication, when found necessary inBlocking and Permissive overreaching schemes.Current reversal and weak-end infeed logic fordistance protection ZCRWPSCHThe current reversal function is used to preventunwanted operations due to current reversalwhen using permissive overreach protectionschemes in application with parallel lines whenthe overreach from the two ends overlap on theparallel line.

    The weak-end infeed logic is used in cases wherethe apparent power behind the protection can betoo low to activate the distance protectionfunction. When activated, received carrier signaltogether with local undervoltage criteria and noreverse zone operation gives an instantaneoustrip. The received signal is also echoed back toaccelerate the sending end.Three phase or phase segregated scheme logic isavailable.Current reversal and weak-end infeed logic forphase segregated communication ZC1WPSCHCurrent reversal and weak-end infeed logic forphase segregated communication (ZC1WPSCH)function is used to prevent unwanted operationsdue to current reversal when using permissiveoverreach protection schemes in application withparallel lines when the overreach from the twoends overlaps on the parallel line.The weak-end infeed logic is used in cases wherethe apparent power behind the protection can betoo low to activate the distance protectionfunction. When activated, received carrier signaltogether with local under voltage criteria and noreverse zone operation gives an instantaneoustrip. The received signal is also echoed back toaccelerate the sending end.Local acceleration logic ZCLCPLALTo achieve fast clearing of faults on the wholeline, when no communication channel is available,local acceleration logic (ZCLCPLAL) can be used.This logic enables fast fault clearing during certainconditions, but naturally, it can not fully replace acommunication channel.The logic can be controlled either by theautorecloser (zone extension) or by the loss-of-load current (loss-of-load acceleration).Scheme communication logic for residualovercurrent protection ECPSCHTo achieve fast fault clearance of earth faults onthe part of the line not covered by theinstantaneous step of the residual overcurrentprotection, the directional residual overcurrentprotection can be supported with a logic thatuses communication channels.In the directional scheme, information of the faultcurrent direction must be transmitted to the other

  • line end. With directional comparison, a shortoperate time of the protection including a channeltransmission time, can be achieved. This shortoperate time enables rapid autoreclosing functionafter the fault clearance.The communication logic module for directionalresidual current protection enables blocking aswell as permissive under/overreaching schemes.The logic can also be supported by additionallogic for weak-end infeed and current reversal,included in Current reversal and weak-end infeedlogic for residual overcurrent protection(ECRWPSCH) function.Current reversal and weak-end infeed logic forresidual overcurrent protection ECRWPSCHThe Current reversal and weak-end infeed logicfor residual overcurrent protection ECRWPSCH isa supplement to Scheme communication logic forresidual overcurrent protection ECPSCH.To achieve fast fault clearing for all earth faults onthe line, the directional earth-fault protectionfunction can be supported with logic that usescommunication channels.The 670 series IEDs have for this reason availableadditions to scheme communication logic.If parallel lines are connected to common busbarsat both terminals, overreaching permissivecommunication schemes can trip unselectivelydue to fault current reversal. This unwantedtripping affects the healthy line when a fault iscleared on the other line. This lack of security canresult in a total loss of interconnection betweenthe two buses. To avoid this type of disturbance,a fault current reversal logic (transient blockinglogic) can be used.Permissive communication schemes for residualovercurrent protection can basically operate onlywhen the protection in the remote IED can detectthe fault. The detection requires a sufficientminimum residual fault current, out from this IED.The fault current can be too low due to anopened breaker or high-positive and/or zero-sequence source impedance behind this IED. Toovercome these conditions, weak-end infeed(WEI) echo logic is used.

    12. LogicTripping logic SMPPTRCA function block for protection tripping isprovided for each circuit breaker involved in thetripping of the fault. It provides pulse prolongationto ensure a trip pulse of sufficient length, as wellas all functionality necessary for correct co-operation with autoreclosing functions.The trip function block also includes functionalityfor evolving faults and breaker lock-out.Trip matrix logic TMAGGIOTrip matrix logic TMAGGIO function is used toroute trip signals and other logical output signalsto different output contacts on the IED.TMAGGIO output signals and the physical outputsallows the user to adapt the signals to thephysical tripping outputs according to the specificapplication needs.Fixed signal function blockThe Fixed signals function (FXDSIGN) generates anumber of pre-set (fixed) signals that can be usedin the configuration of an IED, either for forcingthe unused inputs in other function blocks to acertain level/value, or for creating certain logic.

    13. MonitoringMeasurements CVMMXN, CMMXU, VNMMXU,VMMXU, CMSQI, VMSQIThe measurement functions are used to get on-line information from the IED. These servicevalues make it possible to display on-lineinformation on the local HMI and on theSubstation automation system about:

    measured voltages, currents, frequency,active, reactive and apparent power andpower factor

    primary and secondary phasors positive, negative and zero sequence

    currents and voltages mA, input currents pulse counters

  • control represent various parameters such asfrequency, temperature and DC battery voltage aslow current values, usually in the range 4-20 mAor 0-20 mA.Alarm limits can be set and used as triggers, e.g.to generate trip or alarm signals.The function requires that the IED is equippedwith the mA input module.Disturbance report DRPRDREComplete and reliable information aboutdisturbances in the primary and/or in thesecondary system together with continuous event-logging is accomplished by the disturbance reportfunctionality.Disturbance report DRPRDRE, always included inthe IED, acquires sampled data of all selectedanalog input and binary signals connected to thefunction block with a, maximum of 40 analog and96 binary signals.The Disturbance report functionality is a commonname for several functions:

    Event list Indications Event recorder Trip value recorder Disturbance recorder Fault locator

    The Disturbance report function is characterizedby great flexibility regarding configuration, startingconditions, recording times, and large storagecapacity.A disturbance is defined as an activation of aninput to the AxRADR or BxRBDR function blocks,which are set to trigger the disturbance recorder.All signals from start of pre-fault time to the endof post-fault time will be included in the recording.Every disturbance report recording is saved in theIED in the standard Comtrade format. The sameapplies to all events, which are continuouslysaved in a ring-buffer. The local HMI is used toget information about the recordings. Thedisturbance report files may be uploaded toPCM600 for further analysis using the disturbancehandling tool.

    Event list DRPRDREContinuous event-logging is useful for monitoringthe system from an overview perspective and is acomplement to specific disturbance recorderfunctions.The event list logs all binary input signalsconnected to the Disturbance report function. Thelist may contain up to 1000 time-tagged eventsstored in a ring-buffer.Indications DRPRDRETo get fast, condensed and reliable informationabout disturbances in the primary and/or in thesecondary system it is important to know, forexample binary signals that have changed statusduring a disturbance. This information is used inthe short perspective to get information via thelocal HMI in a straightforward way.There are three LEDs on the local HMI (green,yellow and red), which will display statusinformation about the IED and the Disturbancereport function (triggered).The Indication list function shows all selectedbinary input signals connected to the Disturbancereport function that have changed status during adisturbance.Event recorder DRPRDREQuick, complete and reliable information aboutdisturbances in the primary and/or in thesecondary system is vital, for example, time-tagged events logged during disturbances. Thisinformation is used for different purposes in theshort term (for example corrective actions) and inthe long term (for example functional analysis).The event recorder logs all selected binary inputsignals connected to the Disturbance reportfunction. Each recording can contain up to 150time-tagged events.The event recorder information is available for thedisturbances locally in the IED.The event recording information is an integratedpart of the disturbance record (Comtrade file).

  • Trip value recorder DRPRDREInformation about the pre-fault and fault values forcurrents and voltages are vital for the disturbanceevaluation.The Trip value recorder calculates the values of allselected analog input signals connected to theDisturbance report function. The result ismagnitude and phase angle before and during thefault for each analog input signal.The trip value recorder information is available forthe disturbances locally in the IED.The trip value recorder information is anintegrated part of the disturbance record(Comtrade file).Disturbance recorder DRPRDREThe Disturbance recorder function supplies fast,complete and reliable information aboutdisturbances in the power system. It facilitatesunderstanding system behavior and relatedprimary and secondary equipment during andafter a disturbance. Recorded information is usedfor different purposes in the short perspective (forexample corrective actions) and long perspective(for example functional analysis).The Disturbance recorder acquires sampled datafrom selected analog- and binary signalsconnected to the Disturbance report function(maximum 40 analog and 96 binary signals). Thebinary signals available are the same as for theevent recorder function.The function is characterized by great flexibilityand is not dependent on the operation ofprotection functions. It can record disturbancesnot detected by protection functions. Up to tenseconds of data before the trigger instant can besaved in the disturbance file.The disturbance recorder information for up to100 disturbances are saved in the IED and thelocal HMI is used to view the list of recordings.Event functionWhen using a Substation Automation system withLON or SPA communication, time-tagged eventscan be sent at change or cyclically from the IEDto the station level. These events are created fromany available signal in the IED that is connected

    to the Event function (EVENT). The event functionblock is used for LON and SPA communication.Analog and double indication values are alsotransferred through EVENT function.IEC61850 generic communication I/O functionSPGGIOIEC61850 generic communication I/O functions(SPGGIO) is used to send one single logical signalto other systems or equipment in the substation.IEC61850 generic communication I/O functionsMVGGIOIEC61850 generic communication I/O functions(MVGGIO) function is used to send theinstantaneous value of an analog signal to othersystems or equipment in the substation. It canalso be used inside the same IED, to attach aRANGE aspect to an analog value and to permitmeasurement supervision on that value.Measured value expander block RANGE_XPThe current and voltage measurements functions(CVMMXN, CMMXU, VMMXU and VNMMXU),current and voltage sequence measurementfunctions (CMSQI and VMSQI) and IEC 61850generic communication I/O functions (MVGGIO)are provided with measurement supervisionfunctionality. All measured values can besupervised with four settable limits: low-low limit,low limit, high limit and high-high limit. Themeasure value expander block (RANGE_XP) hasbeen introduced to enable translating the integeroutput signal from the measuring functions to 5binary signals: below low-low limit, below lowlimit, normal, above high-high limit or above highlimit. The output signals can be used asconditions in the configurable logic or for alarmingpurpose.Fault locator LMBRFLOThe accurate fault locator is an essentialcomponent to minimize the outages after apersistent fault and/or to pin-point a weak spoton the line.The fault locator is an impedance measuringfunction giving the distance to the fault in percent,km or miles. The main advantage is the highaccuracy achieved by compensating for loadcurrent and for the mutual zero-sequence effecton double circuit lines.

  • The compensation includes setting of the remoteand local sources and calculation of thedistribution of fault currents from each side. Thisdistribution of fault current, together withrecorded load (pre-fault) currents, is used toexactly calculate the fault position. The fault canbe recalculated with new source data at theactual fault to further increase the accuracy.Especially on heavily loaded long lines (where thefault locator is most important) where the sourcevoltage angles can be up to 35-40 degrees apartthe accuracy can be still maintained with theadvanced compensation included in fault locator.

    14. MeteringPulse counter logic PCGGIOPulse counter (PCGGIO) function countsexternally generated binary pulses, for instancepulses coming from an external energy meter, forcalculation of energy consumption values. Thepulses are captured by the binary input moduleand then read by the function. A scaled servicevalue is available over the station bus. The specialBinary input module with enhanced pulsecounting capabilities must be ordered to achievethis functionality.Function for energy calculation and demandhandling ETPMMTROutputs from the Measurements (CVMMXN)function can be used to calculate energyconsumption. Active as well as reactive values arecalculated in import and export direction. Valuescan be read or generated as pulses. Maximumdemand power values are also calculated by thefunction.

  • IEC 61850-8-1 communication protocol LON communication protocol SPA or IEC 60870-5-103 communication

    protocol DNP3.0 communication protocol

    Theoretically, several protocols can be combinedin the same IED.IEC 61850-8-1 communication protocolThe IED is equipped with single or double opticalEthernet rear ports (order dependent) for IEC61850-8-1 station bus communication. The IEC61850-8-1 communication is also possible fromthe optical Ethernet front port. IEC 61850-8-1protocol allows intelligent electrical devices (IEDs)from different vendors to exchange informationand simplifies system engineering. Peer-to-peercommunication according to GOOSE is part ofthe standard. Disturbance files uploading isprovided.Serial communication, LONExisting stations with ABB station bus LON canbe extended with use of the optical LONinterface. This allows full SA functionality includingpeer-to-peer messaging and cooperationbetween existing ABB IED's and the new IED 670.SPA communication protocolA single glass or plastic port is provided for theABB SPA protocol. This allows extensions ofsimple substation automation systems but themain use is for Substation Monitoring SystemsSMS.IEC 60870-5-103 communication protocolA single glass or plastic port is provided for theIEC60870-5-103 standard. This allows design ofsimple substation automation systems includingequipment from different vendors. Disturbancefiles uploading is provided.DNP3.0 communication protocolAn electrical RS485 and an optical Ethernet portis available for the DNP3.0 communication. DNP3.0 Level 2 communication with unsolicited events,time synchronizing and disturbance reporting isprovided for communication to RTUs, Gatewaysor HMI systems.Multiple command and transmitWhen 670 IED's are used in SubstationAutomation systems with LON, SPA or

    IEC60870-5-103 communication protocols theEvent and Multiple Command function blocks areused as the communication interface for verticalcommunication to station HMI and gateway andas interface for horizontal peer-to-peercommunication (over LON only).IEC 62439-3 Parallel Redundant ProtocolRedundant station bus communication accordingto IEC 62439-3 Edition 1 and IEC 62439-3 Edition2 are available as options in 670 series IEDs. IEC62439-3 parallel redundant protocol is an optionalquantity and the selection is made at ordering.Redundant station bus communication accordingto IEC 62439-3 uses both port AB and port CDon the OEM module.

    Select IEC 62439-3 Edition 1protocol at the time of orderingwhen an existing redundantstation bus DuoDriverinstallation is extended.Select IEC 62439-3 Edition 2protocol at the time of orderingfor new installations withredundant station bus.IEC 62439-3 Edition 1 is NOTcompatible with IEC 62439-3Edition 2.

    18. Remote communicationAnalog and binary signal transfer to remote endThree analog and eight binary signals can beexchanged between two IEDs. This functionality ismainly used for the line differential protection.However it can be used in other products as well.An IED can communicate with up to 4 remoteIEDs.Binary signal transfer to remote end, 192 signalsIf the communication channel is used for transferof binary signals only, up to 192 binary signalscan be exchanged between two IEDs. Forexample, this functionality can be used to sendinformation such as status of primary switchgearapparatus or intertripping signals to the remoteIED. An IED can communicate with up to 4remote IEDs.

  • Galvanic X.21 line data communication module X.21-LDCMThe galvanic X.21 line data communicationmodule is used for connection totelecommunication equipment, for exampleleased telephone lines. The module supports 64kbit/s data communication between IEDs.Examples of applications:

    Line differential protection Binary signal transfer

    Galvanic RS485 serial communication moduleThe Galvanic RS485 communication module(RS485) is used for DNP3.0 communication. Themodule has one RS485 communication port. TheRS485 is a balanced serial communication thatcan be used either in 2-wire or 4-wireconnections. A 2-wire connection uses the samesignal for RX and TX and is a multidropcommunication with no dedicated Master orslave. This variant requires however a control ofthe output. The 4-wire connection has separatedsignals for RX and TX multidrop communicationwith a dedicated Master and the rest are slaves.No special control signal is needed in this case.GPS time synchronization module GTMThis module includes a GPS receiver used fortime synchronization. The GPS has one SMA

    contact for connection to an antenna. It alsoincludes an optical PPS ST-connector output.IRIG-B Time synchronizing moduleThe IRIG-B time synchronizing module is used foraccurate time synchronizing of the IED from astation clock.Transformer input module TRMThe transformer input module is used togalvanically separate and transform the secondarycurrents and voltages generated by themeasuring transformers. The module has twelveinputs in different combinations of currents andvoltage inputs.Alternative connectors of Ring lug orCompression type can be ordered.High impedance resistor unitThe high impedance resistor unit, with resistorsfor pick-up value setting and a voltage dependentresistor, is available in a single phase unit and athree phase unit. Both are mounted on a 1/1 19inch apparatus plate with compression typeterminals.Layout and dimensionsDimensions
