1. 650 series overview
The 650 series IEDs provide optimum 'off-the-shelf', ready-to-use solutions. It is configuredwith complete protection functionality anddefault parameters to meet the needs of awide range of applications for generationtransmission and sub-transmission grids.
The 650 series IEDs include:
• Complete ready-made solutions optimizedfor a wide range of applications forgeneration, transmission and sub-transmission grids.
• Support for user-defined names in the locallanguage for signal and functionengineering.
• Minimized parameter setting based ondefault values and ABB's new global basevalue concept. You only need to set thoseparameters specific to your ownapplication, such as the line data.
• GOOSE messaging for horizontalcommunication.
• Extended HMI functionality with 15dynamic three-color-indication LEDs perpage, on up to three pages, andconfigurable push-button shortcuts fordifferent actions.
• Programmable LED text-based labels.• Settable 1A/5A -rated current inputs.
2. Application
REG650 is used for the protection andmonitoring of generating plants. The IED isespecially suitable for applications indistributed control systems with highdemands on reliability. It is intended mainlyfor small and medium size generation stations.
REG670 may be used when more extensiveprotection systems are required or incombination with REG650 to provideredundant schemes.
A wide range of protection functions isavailable to achieve full and reliableprotection for different types of generatingplants, for example hydro power plants andthermal power plants. This enablesadaptation to the protection requirements ofmost generating plants.
Protection functions are available fordetecting and clearing internal faults, such asgenerator stator short circuits and earthfaults, generator rotor earth faults, unittransformer short circuits and earth faults andfaults in the external power system, fed fromthe generating plant.
Two packages have been defined for thefollowing applications:
• Generator protection IED includinggenerator differential protection (B01)
• Generator-transformer unit protectionIED including transformer differentialprotection (B05)
In many generating plants, the protectionsystem can be designed with a combinationof the two packages, that is, two IEDs ofeither same type or different types, will giveredundant protection for a generating unit(generator and unit transformer) dependingon the requirements for the plant design.
The packages are configured and ready foruse. Analogue inputs and binary input/outputcircuits are pre-defined.
The pre-configured IED can be changed andadapted with the graphical configuration tool.

Figure 3. CT group arrangement fordifferential protection andother protections
The setting facilities cover for applications ofthe differential protection to all types ofpower transformers and auto-transformerswith or without load tap changer as well asfor shunt reactors or and local feeders within
the station. An adaptive stabilizing feature isincluded for heavy through-faults.
Stabilization is included for inrush currents aswell as for overexcitation condition. Adaptivestabilization is also included for systemrecovery inrush and CT saturation forexternal faults. A high set unrestraineddifferential current protection is included fora very high speed tripping at a high internalfault currents.
An innovative sensitive differential protectionfeature, based on the theory of symmetricalcomponents, offers the best possiblecoverage for power transformer winding turn-to-turn faults.
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 magnetizingcharacteristics. It utilizes an externalsummation of the currents in theinterconnected CTs and a series resistor and avoltage dependent resistor externally to theIED.
HZPDIF can be used as high impedance REFprotection.
Generator differential protectionGENPDIF
Short circuit between the phases of the statorwindings causes normally very large faultcurrents. The short circuit gives risk ofdamages on insulation, windings and statoriron core. The large short circuit currentscause large forces, which can cause damageeven to other components in the powerplant, such as turbine and generator-turbineshaft.
The task of Generator differential protectionGENPDIF is to determine whether a fault iswithin the protected zone, or outside theprotected zone. If the fault is internal, thefaulty generator must be quickly tripped, thatis, disconnected from the network, the field

breaker tripped and the power to the primemover interrupted.
To limit the damage due to stator windingshort circuits, the fault clearance must be asfast as possible (instantaneous). If thegenerator block is connected to the powersystem close to other generating blocks, thefast fault clearance is essential to maintain thetransient stability of the non-faultedgenerators.
Normally, the short circuit fault current isvery large, that is, significantly larger than thegenerator rated current. There is a risk that ashort circuit can occur between phases closeto the neutral point of the generator, thuscausing a relatively small fault current. Thefault current can also be limited due to lowexcitation of the generator. Therefore, it isdesired that the detection of generator phase-to-phase short circuits shall be relativelysensitive, detecting small fault currents.
It is also of great importance that thegenerator differential protection does not tripfor external faults, with large fault currentsflowing from the generator. To combine fastfault clearance, as well as sensitivity andselectivity, the generator differentialprotection is normally the best choice forphase-to-phase generator short circuits. Anegative-sequence-current-based internal-external fault discriminator can be used todetermine whether a fault is internal orexternal. The internal-external faultdiscriminator not only positivelydiscriminates between internal and externalfaults, but can independently detect minorfaults which may not be felt (until theydevelop into more serious faults) by the"usual" differential protection based onoperate-restrain characteristic.
An open CT circuit condition createsunexpected operations for Generatordifferential protection under the normal loadconditions. It is also possible to damagesecondary equipment due to high voltageproduced from open CT circuit outputs.Therefore, it may be a requirement fromsecurity and reliability points of view to have
open CT detection function to blockGenerator differential protection function incase of open CT conditions and at the sametime produce the alarm signal to theoperational personal to make quick remedyactions to correct the open CT condition.
Generator differential protection GENPDIF isalso well suited to generate fast, sensitive andselective fault clearance, if used to protectshunt reactors or small busbars
5. Impedance protection
Underimpedance protection forgenerators and transformersZGPDIS
The underimpedance protection forgenerators and transformers ZGPDIS, has theoffset mho characteristic as a three zone back-up protection for detection of short circuits intransformers and generators. The three zoneshave independent measuring and settingsthat gives high flexibility for all types ofapplications.
Load encroachment characteristic is availablefor third zone as shown in figure 4.

Loss of excitation LEXPDIS
There are limits for the low excitation of asynchronous machine. A reduction of theexcitation current weakens the couplingbetween the rotor and the stator. Themachine may lose the synchronism and startto operate like an induction machine. Then,the reactive power consumption willincrease. Even if the machine does not loosesynchronism it may not be acceptable tooperate in this state for a long time.Reduction of excitation increases thegeneration of heat in the end region of thesynchronous machine. The local heating maydamage the insulation of the stator windingand the iron core.
To prevent damages to the generator itshould be tripped when excitation becomestoo low.
Out-of-step protection OOSPPAM
Out-of-step protection (OOSPPAM) functionin the IED can be used both for generatorprotection application as well as, lineprotection applications.
The main purpose of the OOSPPAM functionis to detect, evaluate, and take the requiredaction during pole slipping occurrences inthe power system.
The OOSPPAM function detects pole slipconditions and trips the generator as fast aspossible, that is after the first pole-slip if thecentre of oscillation is found to be in zone 1which normally includes the generator and itsstep-up power transformer. If the centre ofoscillation is found to be further out in thepower system, that is, in zone 2, more thanone pole-slip is usually allowed before thegenerator-transformer unit is disconnected. Ifthere are several out-of-step relays in thepower system, then one which finds thecentre of oscillation in its zone 1 shalloperate first.
Load encroachment LEPDIS
Heavy load transfer is common in manypower networks and may make fault
resistance coverage difficult to achieve. Insuch a case, Load encroachment (LEPDIS)function can be used to enlarge the resistivesetting of the underimpedance measuringzones without interfering with the load.

ABB 17
circuit 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, for
operating quantity. There is also availableone non-directional 3I0 step and one non-
directional 3U0 overvoltage tripping step.
Thermal overload protection, twotime constant TRPTTR
If a power transformer or generator reachesvery high temperatures the equipment mightbe damaged. The insulation within thetransformer/generator will have forcedageing. As a consequence of this the risk ofinternal phase-to-phase or phase-to-earthfaults will increase. High temperature willdegrade the quality of the transformer/generator insulation.
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 a trip of the protected transformer/generator.
Breaker failure protection CCRBRF
Breaker failure protection (CCRBRF) ensuresfast back-up tripping of surrounding breakersin case the own breaker failure to open.CCRBRF can be current based, contact based,or an adaptive combination of these twoprinciples.
A current check with extremely short resettime is used as check criterion to achieve ahigh security against unnecessary operation.
A contact check criteria can be used wherethe fault current through the breaker is small.
Breaker failure protection (CCRBRF) currentcriteria can be fulfilled by one or two phasecurrents, or one phase current plus residualcurrent. When those currents exceed the userdefined settings, the function is activated.These conditions increase the security of theback-up trip command.
CCRBRF function can be programmed to givea three-phase re-trip of the own breaker toavoid unnecessary tripping of surroundingbreakers at an incorrect initiation due tomistakes during testing.
Pole discordance protectionCCRPLD
Circuit breakers and disconnectors can endup with the poles in different positions (close-open), due to electrical or mechanicalfailures. This can cause negative and zerosequence currents which cause thermal stresson 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 breakers should betripped to clear the unsymmetrical loadsituation.
The pole discordance function operates basedon information from the circuit breaker logicwith additional criteria from unsymmetricalphase currents when required.
Directional over/underpowerprotection GOPPDOP/GUPPDUP
The directional over-/under-power protectionGOPPDOP/GUPPDUP can be used wherevera high/low active, reactive or apparent powerprotection or alarming is required. Thefunctions can alternatively be used to checkthe direction of active or reactive power flowin the power system. There are a number ofapplications where such functionality isneeded. 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 both steps can beset as well.
Accidental energizing protectionfor synchronous generatorAEGGAPC
Inadvertent or accidental energizing of off-line generators has occurred often enoughdue to operating errors, breaker headflashovers, control circuit malfunctions, or acombination of these causes. Inadvertentlyenergized generator operates as inductionmotor drawing a large current from thesystem. The voltage supervised overcurrentprotection is used to protect the inadvertentlyenergized generator.
Accidental energizing protection forsynchronous generator (AEGGAPC) takes themaximum phase current input from thegenerator terminal side or from generatorneutral side and maximum phase to phasevoltage inputs from the terminal side.AEGGAPC is armed when the terminalvoltage drops below the specified voltagelevel for the preset time.
Negative sequence time overcurrentprotection for machines NS2PTOC
Negative-sequence time overcurrentprotection for machines NS2PTOC is intendedprimarily for the protection of generatorsagainst possible overheating of the rotorcaused by negative sequence component inthe stator current.
The negative sequence currents in agenerator may, among others, be caused by:
• Unbalanced loads• Line to line faults• Line to earth faults• Broken conductors• Malfunction of one or more poles of a
circuit breaker or a disconnector
NS2PTOC can also be used as a backupprotection, that is, to protect the generator in
the event line protections or circuit breakersfail to clear unbalanced system faults.
To provide an effective protection for thegenerator for external unbalanced conditions,NS2PTOC is able to directly measure thenegative sequence current. NS2PTOC also hasa time delay characteristic which matches theheating characteristic of the generator
22I t K= as defined in standard.
where:
I2 is negative sequence currentexpressed in per unit of the ratedgenerator current
t is operating time in seconds
K is a constant which depends of thegenerators size and design
NS2PTOC has a wide range of K settings andthe sensitivity and capability of detecting andtripping for negative sequence currents downto the continuous capability of a generator.
A separate output is available as an alarmfeature to warn the operator of a potentiallydangerous situation.
Voltage-restrained time overcurrentprotection VR2PVOC

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.
UV2PTUV has two voltage steps, where step1 is settable as inverse or definite timedelayed. Step 2 is always definite time delayed.

OV2PTOV has two voltage steps, where step1 can be set as inverse or definite timedelayed. Step 2 is always definite time delayed.
OV2PTOV has an extremely high reset ratioto allow settings close to system servicevoltage.
Two step residual overvoltageprotection ROV2PTOV
Residual voltages may occur in the powersystem during earth faults.
Two step residual overvoltage protectionROV2PTOV function calculates the residualvoltage from the three-phase voltage inputtransformers or measures it from a singlevoltage input transformer fed from an opendelta or neutral point voltage transformer.
ROV2PTOV has two voltage steps, wherestep 1 can be set as inverse or definite timedelayed. Step 2 is always definite time delayed.
Overexcitation protectionOEXPVPH
When the laminated core of a powertransformer or generator is subjected to a
magnetic 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. The functionhas settable inverse operating curves andindependent alarm stages.
95% and 100% Stator earth faultprotection based on 3rd harmonicSTEFPHIZ
Stator earth fault is a fault type havingrelatively high fault rate. The generatorsystems normally have high impedanceearthing, that is, earthing via a neutral pointresistor. This resistor is normallydimensioned to give an earth fault current inthe range 3 – 15 A at a solid earth-faultdirectly at the generator high voltageterminal. The relatively small earth faultcurrents give much less thermal andmechanical stress on the generator, comparedto the short circuit case, which is betweenconductors of two phases. Anyhow, the earthfaults in the generator have to be detectedand the generator has to be tripped, even iflonger fault time compared to internal shortcircuits, can be allowed.
In normal non-faulted operation of thegenerating unit the neutral point voltage isclose to zero, and there is no zero sequencecurrent flow in the generator. When a phase-to-earth fault occurs the neutral point voltagewill increase and there will be a current flowthrough the neutral point resistor.
To detect an earth fault on the windings of agenerating unit one may use a neutral pointovervoltage protection, a neutral pointovercurrent protection, a zero sequenceovervoltage protection or a residualdifferential protection. These protections aresimple and have served well during manyyears. However, at best these simple schemesprotect only 95% of the stator winding. Theyleave 5% close to the neutral endunprotected. Under unfavorable conditions
Generator protection REG650 1MRK 502 036-BEN -Product version: 1.1 Issued: February 2011
20 ABB
the blind zone may extend up to 20% fromthe neutral.
The 95% stator earth fault protectionmeasures the fundamental frequency voltagecomponent in the generator star point and itoperates when it exceeds the preset value. Byapplying this principle approximately 95% ofthe stator winding can be protected. In orderto protect the last 5% of the stator windingclose to the neutral end the 3rd harmonic
voltage measurement can be performed. In100% Stator E/F 3rd harmonic protectioneither the 3rd harmonic voltage differentialprinciple, the neutral point 3rd harmonicundervoltage principle or the terminal side3rd harmonic overvoltage principle can beapplied. However, differential principle isstrongly recommended. Combination of thesetwo measuring principles provides coveragefor entire stator winding against earth faults.

Rotor earth fault protection 64R
Generator rotor winding and its associated dcsupply electric circuit is typically fullyinsulated from the earth (that is, ground).Therefore single connection of this circuit toearth will not cause flow of any substantialcurrent. However if second earth faultappears in this circuit circumstances can bequit serious. Depending on the location ofthese two faults such operating conditionmay cause:
• Partial or total generator loss of field• Large dc current flow through rotor
magnetic circuit• Rotor vibration• Rotor displacement sufficient to cause
stator mechanical damage
Therefore practically all bigger generatorshave some dedicated protection which iscapable to detect the first earth fault in therotor circuit and then, depending on the faultresistance, either just to give an alarm to theoperating personnel or actually to give stopcommand to the machine. Requires injectionunit for rotor earth fault protection (RXTTE4)and a protective resistor on plate for correctoperation.

9. Secondary systemsupervision
Fuse failure supervision SDDRFUF
The aim of the fuse failure supervisionfunction (SDDRFUF) is to block voltagemeasuring functions at failures in thesecondary circuits between the voltagetransformer and the IED in order to avoidunwanted operations that otherwise mightoccur.
The fuse failure supervision function basicallyhas three different algorithms, negativesequence and zero sequence basedalgorithms and an additional delta voltageand delta current algorithm.
The negative sequence detection algorithm isrecommended for IEDs used in isolated orhigh-impedance earthed networks. It is basedon the negative-sequence measuringquantities, a high value of voltage 3U2
without the presence of the negative-sequence current 3I2.
The zero sequence detection algorithm isrecommended for IEDs used in directly orlow impedance earthed networks. It is basedon the zero sequence measuring quantities, ahigh value of voltage 3U0 without the
presence of the residual current 3I0.
A criterion based on delta current and deltavoltage measurements can be added to thefuse failure supervision function in order todetect a three phase fuse failure, which inpractice is more associated with voltagetransformer switching during stationoperations.
For better adaptation to system requirements,an operation mode setting has beenintroduced which makes it possible to selectthe operating conditions for negativesequence and zero sequence based function.The selection of different operation modes

In the IED, the internal time can besynchronized from a number of sources:
• SNTP• IRIG-B• DNP• IEC60870-5-103
Parameter setting groups ACTVGRP
Use the four sets of settings to optimize theIED operation for different system conditions.Creating and switching between fine-tunedsetting sets, either from the local HMI orconfigurable binary inputs, results in a highlyadaptable IED that can cope with a variety ofsystem scenarios.
Test mode functionality TESTMODE
The protection and control IEDs have manyincluded functions. To make the testingprocedure easier, the IEDs include the featurethat allows individual blocking of a single-,several-, or all functions.
There are two ways of entering the test mode:
• By configuration, activating an inputsignal of the function block TESTMODE
• By setting the IED in test mode in thelocal HMI
While the IED is in test mode, all functionsare blocked.
Any function can be unblocked individuallyregarding functionality and event signaling.This enables the user to follow the operationof one or several related functions to checkfunctionality and to check parts of theconfiguration, and so on.
Change lock function CHNGLCK
Change lock function (CHNGLCK) is used toblock further changes to the IEDconfiguration and settings once thecommissioning is complete. The purpose is toblock inadvertent IED configuration changesbeyond a certain point in time.
Authority status ATHSTAT
Authority status (ATHSTAT) function is anindication function block for user log-onactivity.
Authority check ATHCHCK
To safeguard the interests of our customers,both the IED and the tools that are accessingthe IED are protected, by means ofauthorization handling. The authorizationhandling of the IED and the PCM600 isimplemented at both access points to the IED:
• local, through the local HMI• remote, through the communication ports
16. Stationcommunication
IEC 61850-8-1 communicationprotocol
The IED supports the communicationprotocols IEC 61850-8-1 and DNP3 over TCP/IP. All operational information and controlsare available through these protocols.However, some communication functionality,for example, horizontal communication(GOOSE) between the IEDs, is only enabledby the IEC 61850-8-1 communication protocol.
The IED is equipped with an optical Ethernetrear port for the substation communicationstandard IEC 61850-8-1. IEC 61850-8-1protocol allows intelligent electrical devices(IEDs) from different vendors to exchangeinformation and simplifies systemengineering. Peer-to-peer communicationaccording to GOOSE is part of the standard.Disturbance files uploading is provided.
Disturbance files are accessed using the IEC61850-8-1 protocol. Disturbance files areavailable to any Ethernet based applicationvia FTP in the standard Comtrade format.Further, the IED can send and receive binary

values, double point values and measuredvalues (for example from MMXU functions),together with their quality, using the IEC61850-8-1 GOOSE profile. The IED meets theGOOSE performance requirements fortripping applications in substations, asdefined by the IEC 61850 standard. The IEDinteroperates with other IEC 61850-compliantIEDs, tools, and systems and simultaneouslyreports events to five different clients on theIEC 61850 station bus.
The event system has a rate limiter to reduceCPU load. The event channel has a quota of10 events/second. If the quota is exceededthe event channel transmission is blockeduntil the event changes is below the quota,no event is lost.
All communication connectors, except for thefront port connector, are placed on integratedcommunication modules. The IED isconnected to Ethernet-based communicationsystems via the fibre-optic multimode LCconnector (100BASE-FX).
The IED supports SNTP and IRIG-B timesynchronization methods with a time-stamping resolution of 1 ms.
• Ethernet based: SNTP and DNP3• With time synchronization wiring: IRIG-B
The IED supports IEC 60870-5-103 timesynchronization methods with a timestamping resolution of 5 ms.

Horizontal communication viaGOOSE for interlocking
GOOSE communication can be used forexchanging information between IEDs via theIEC 61850-8-1 station communication bus.This is typically used for sending apparatusposition indications for interlocking orreservation signals for 1-of-n control. GOOSEcan also be used to exchange any boolean,integer, double point and analog measuredvalues between IEDs.
DNP3 protocol
DNP3 (Distributed Network Protocol) is a setof communications protocols used tocommunicate data between components inprocess automation systems. For a detaileddescription of the DNP3 protocol, see theDNP3 Communication protocol manual.
IEC 60870-5-103 communicationprotocol
IEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serialcommunication exchanging information witha control system, and with a data transfer rateup to 38400 bit/s. In IEC terminology, aprimary station is a master and a secondarystation is a slave. The communication isbased on a point-to-point principle. Themaster must have software that can interpretIEC 60870-5-103 communication messages.
