SIPROTEC Compact 7RW80Voltage and Frequency Relay

The SIPROTEC Compact 7RW80 is a nu-merical, multifunction relay for connec-tion to voltage transformers. It can be usedin distribution systems, on transformersand for electrical machines. If theSIPROTEC Compact 7RW80 detects anydeviation from the permitted voltage, fre-quency or overexcitation values, it will re-spond according to the values set. Therelay can also be applied for the purposesof system decoupling and for load shed-ding if ever there is a risk of a systemcollapse as a result of inadmissibly largefrequency drops. An integrated load resto-ration function allows the re-establishmentof the power system after recovery of thesystem frequency.

The 7RW80 features “flexible protectionfunctions”. 20 additional protection func-tions can be created by the user. For exam-ple, a rate-of-frequency change or a rate-of-voltage change function can be created.

The relay provides circuit-breaker control,additional primary switching devices(grounding switches, transfer switches andisolating switches) can also be controlledfrom the relay. Automation or PLC logicfunctionality is also implemented in therelay. The integrated programmable logic(CFC) allows the user to add own func-tions, e.g. for the automation of switch-gear (including: interlocking, transfer andload shedding schemes). The user is alsoallowed to generate user-defined messages.

The communication module is independ-ent from the protection. It can easily beexchanged or upgraded to future commu-nication protocols.

Highlights

Removable terminals provide the ideal so-lution for fast and secure replacement ofrelays. Binary input thresholds are softwaresettings. There is thus no need to ever openthe relay to adapt the hardware configura-tion to a specific application.

The relay provides 9 programmable func-tion keys that can be used to replace push-buttons, select switches and control switches.

The battery for event and fault recordingmemory can be exchanged from the frontof the relay.

The relay is available with IEC 61850 forincredible cost savings in applications (e.g.transfer schemes with synch-check, businterlocking and load shedding schemes).

This compact relay provides protection,control, metering and PLC logic functional-ity. Secure and easy to use one page matrixIO programming is now a standard feature.

The housing creates a sealed dust proofenvironment for the relay internal elec-tronics. Heat build up is dissipated throughthe surface area of the steel enclosure. Nodusty or corrosive air can be circulatedover the electronic components. The relaythus will maintain its tested insulationcharacteristic standards as per IEC, IEEE,even if deployed in harsh environment.

Fig. 2 Function diagram

The SIPROTEC Compact 7RW80 unit is anumerical protection relay that can per-form control and monitoring functionsand therefore provide the user with a cost-effective platform for power system man-agement, that ensures reliable supply ofelectrical power to the customers. The er-gonomic design makes control easy fromthe relay front panel. A large, easy-to-readdisplay was a key design factor.

Control

The integrated control function permitscontrol of disconnect devices, groundingswitches or circuit-breakers through theintegrated operator panel, binary inputs,DIGSI 4 or the control or SCADA/automa-tion system (e.g. SICAM, SIMATIC or othervendors automation system). A full range ofcommand processing functions is provided.

Programmable logic

The integrated logic characteristics (CFC)allow the user to add own functions forautomation of switchgear (e.g. interlock-ing) or switching sequence. The user canalso generate user-defined messages. Thisfunctionality can form the base to createextremely flexible transfer schemes.

Line protection

For the enhancement of the feeder protec-tion the 7RW80 provides several stages forvoltage and frequency protection.

Generator and transformer protection

Through implemented voltage, frequencyand overexcitation protection the 7RW80can be used for generators and transform-ers in case of defective voltage or frequencycontrol, full load rejection or operation inislanding generation systems.

System decoupling and load shedding

For system decoupling and load sheddingthe 7RW80 provides voltage, frequency,rate-of-frequency-change and rate-of-voltage-change protection.

Load restoration

For power system recovery frequency pro-tection and load restoration are available in7RW80.

Metering values

Extensive measured values (e.g. V), andlimit values (e.g. for voltage, frequency)provide improved system management.

Reporting

The storage of event logs, trip logs, faultrecords and statistics documents are storedin the relay to provide the user or operatorwith all the key data required to operatemodern substations.

Switchgear cubicles forhigh/medium voltage

All units are designed specifically to meetthe requirements of high/medium-voltageapplications.

In general, no separate measuring instru-ments (e.g., for voltage, frequency, …) oradditional control components are neces-sary.

Typically the relay provides all requiredmeasurements, thus negating the use ofadditional metering devices like volt orfrequency meters. No additional controlswitches are required either. The relay pro-vides 9 function keys that can be config-ured to replace pushbuttons and selectswitches.

Protection functions

Undervoltage protection (ANSI 27)

The two-element undervoltage protectionprovides protection against dangerousvoltage drops (especially for electric ma-chines). Applications include the isolationof generators or motors from the networkto avoid undesired operating conditionsand a possible loss of stability. Proper op-erating conditions of electrical machinesare best evaluated with the positive-sequence quantities. The protection func-tion is active over a wide frequency rangeof 25 to 70 Hz.

The function can operate either withphase-to-phase, phase-to-ground or posi-tive phase-sequence voltage. Three-phaseand single-phase connections are possible.

In addition a user definable curve with upto 20 value pairs is available.

Overvoltage protection (ANSI 59)

The two-element overvoltage protectiondetects unwanted network and machineovervoltage conditions. The function canoperate either with phase-to-phase,phase-to-ground, positive phase-sequenceor negative phase-sequence voltage.Three-phase and single-phase connectionsare possible.

In addition, a user definable curve with upto 20 value pairs is available.

Frequency protection (ANSI 81O/U)

Frequency protection can be used for over-frequency and underfrequency protection.Electric machines and parts of the systemare protected from unwanted frequencydeviations. Unwanted frequency changesin the network can be detected and theload can be removed at a specified fre-quency setting.

Frequency protection can be used overa wide frequency range of 25 to 70 Hz.There are four elements (individually set asoverfrequency, underfrequency or OFF)and each element can be delayed sepa-rately. Blocking of the frequency protec-tion can be performed by activating abinary input or by using an undervoltageelement.

Construction and hardware

Connection techniques andhousing with many advantages

The relay housing is 1/6 of a 19" rack.The housing is thus identical in size to the7RW600 relays that makes replacementvery easy. The height is 244 mm (9.61").

Pluggable terminals allow for pre-wiringand simplify the exchange of devices.

All binary inputs are independent and thepick-up thresholds are settable using soft-ware settings (3 stages). Up to 9 functionkeys can be programmed for predefinedmenu entries, switching sequences, etc.The assigned function of the function keyscan be shown in the display of the relay.

Load restoration

The load restoration function provides anautomatic reconnection of power systemparts when the system frequency has re-covered after load shedding.

Four load restoration stages are available.They can be switched on and off separately.

If the frequency conditions allow the as-sumption of sufficient generation re-sources, the load restoration function willconsecutively reconnect small load parts atspecified time intervals.

Protection functions (cont'd)

Fig. 4 Flexible protection functions

Overexcitation protection (ANSI 24)

The overexcitation protection serves fordetection of an unpermissible high induc-tion (proportional to V/f) in generators ortransformers, which leads to thermal over-loading. This may occur when starting up,shutting down under full load, with weaksystems or under isolated operation. Theinverse characteristic can be set via eightpoints derived from the manufacturerdata.

In addition, a definite-time alarm stage andan instantaneous stage can be used. For cal-culation of the V/f ratio, frequency and alsothe highest of the three line-to-line voltagesare used. The frequency range that can bemonitored comprises 25 to 70 Hz.

Jump of voltage vector

Monitoring the phase angle in the voltageis a criterion for identifying an interruptedinfeed. If the incoming line should fail, theabrupt current discontinuity leads to aphase angle jump in the voltage. This ismeasured by means of a delta process. Thecommand for opening the generator orcoupler circuit-breaker will be issued if theset threshold is exceeded.

Flexible protection functions

The 7RW80 enables the user to easily addup to 20 additional protective functions.Parameter definitions are used to linkstandard protection logic with any chosencharacteristic quantity (measured or calcu-lated quantity) (Fig. 4). The standard logicconsists of the usual protection elementssuch as the pickup set point, the set delaytime, the TRIP command, a block func-tion, etc. The mode of operation forvoltage quantities can be three-phase orsingle-phase. Almost all quantities can beoperated with ascending or descendingpickup stages (e.g. under and overvoltage).All stages operate with protection priority.

Protection functions/stages available arebased on the available measured analogquantities:

dV/dt><

For example, the following can be imple-mented:

• Rate-of-frequency-change protection(ANSI 81R)

• Rate-of-voltage-change protection

Synch-check (ANSI 25)

When closing a circuit-breaker, the unitscan check whether two separate networksare synchronized. Voltage, frequency andphase-angle-differences are checked to de-termine whether synchronous conditionsexist.

Lockout (ANSI 86)

All binary output statuses can be memo-rized. The LED reset key is used to resetthe lockout state. The lockout state is alsostored in the event of supply voltage fail-ure. Reclosure can only occur after thelockout state is reset.

Trip circuit supervision (ANSI 74TC)

One or two binary inputs can be used formonitoring the circuit-breaker trip coilincluding its incoming cables. An alarmsignal is generated whenever the circuit isinterrupted. The circuit-breaker trip coil ismonitored in the open and closed position.Interlocking features can be implementedto ensure that the beaker can only be closedif the trip coil is functional.

Customized functions

Additional functions, which are not timecritical, can be implemented using the CFCmeasured values.

Control and automatic functions

Control

In addition to the protection functions,the SIPROTEC 4 and SIPROTEC Compactunits also support all control and monitor-ing functions that are required for operat-ing medium-voltage or high-voltagesubstations.

The main application is reliable control ofswitching and other processes.

The status of primary equipment or auxil-iary devices can be obtained from auxiliarycontacts and communicated to the 7RW80via binary inputs. Therefore it is possibleto detect and indicate both the OPEN andCLOSED position or a fault or intermedi-ate circuit-breaker or auxiliary contact po-sition.

The switchgear or circuit-breaker can becontrolled via:

– integrated operator panel– binary inputs– substation control and protection system– DIGSI 4.



Control and automatic functions (cont'd)

Automation / user-defined logic

With integrated logic, the user can create,through a graphic interface (CFC), specificfunctions for the automation of switchgearor a substation. Functions are activated us-ing function keys, a binary input orthrough the communication interface.

Switching authority

Switching authority is determined by setparameters or through communications tothe relay. If a source is set to “LOCAL”,only local switching operations are possi-ble. The following sequence for switchingauthority is available: “LOCAL”; DIGSIPC program, “REMOTE”.

There is thus no need to have a separateLocal/Remote switch wired to the breakercoils and relay. The local/remote selectioncan be done using a function key on thefront of the relay.

Command processing

This relay is designed to be easily integratedinto a SCADA or control system. Securityfeatures are standard and all the function-ality of command processing is offered.This includes the processing of single anddouble commands with or without feed-back, sophisticated monitoring of the con-trol hardware and software, checking ofthe external process, control actions usingfunctions such as runtime monitoring andautomatic command termination afteroutput. Here are some typical applications:

• Single and double commands using 1,1 plus 1 common or 2 trip contacts

• User-definable bay interlocks

• Operating sequences combining severalswitching operations such as control ofcircuit-breakers, disconnectors andgrounding switches

• Triggering of switching operations,indications or alarm by combination withexisting information.

Assignment of feedback to command

The positions of the circuit-breaker orswitching devices and transformer taps areacquired through feedback. These indica-tion inputs are logically assigned to thecorresponding command outputs. Theunit can therefore distinguish whether theindication change is a result of switchingoperation or whether it is an undesiredspontaneous change of state.

Chatter disable

The chatter disable feature evaluateswhether, in a set period of time, the num-ber of status changes of indication inputexceeds a specified number. If exceeded,the indication input is blocked for a certainperiod, so that the event list will not recordexcessive operations.

Indication filtering and delay

Binary indications can be filtered or de-layed.

Filtering serves to suppress brief changes inpotential at the indication input. The indi-cation is passed on only if the indicationvoltage is still present after a set period oftime. In the event of an indication delay,there is a delay for a preset time. The infor-mation is passed on only if the indicationvoltage is still present after this time.

Indication derivation

User-definable indications can be derivedfrom individual or a group of indications.These grouped indications are of greatvalue to the user that need to minimize thenumber of indications sent to the systemor SCADA interface.

Measured values

The r.m.s. values are calculated from theacquired voltages along with the frequency.The following functions are available formeasured value processing:

• Voltages VL1, VL2, VL3, VL1L2, VL2L3, VL3L1

• Symmetrical componentsV1, V2, V0

• Frequency

• Mean as well as minimum and maximumvoltage values

• Operating hours counter

• Limit value monitoringLimit values can be monitored using pro-grammable logic in the CFC. Commandscan be derived from this limit value indi-cation.

• Zero suppressionIn a certain range of very low measuredvalues, the value is set to zero to suppressinterference.

Commissioning

Commissioning could not be easier andis supported by DIGSI 4. The status ofthe binary inputs can be read individuallyand the state of the binary outputs can beset individually. The operation of switch-ing elements (circuit-breakers, disconnectdevices) can be checked using the switch-ing functions of the relay. The analogmeasured values are represented as wide-ranging operational measured values. Toprevent transmission of information tothe control center during maintenance,the communications can be disabled toprevent unnecessary data from being trans-mitted. During commissioning, all indica-tions with test tag for test purposes can beconnected to a control and protectionsystem.

Test operation

During commissioning, all indications canbe passed to a control system for test pur-poses.

The relay offers flexibility with reference toits communication to substation automa-tion systems and industrial SCADA orDCS systems. The communication modulefirmware can be changed to communicateusing another protocol or the modules canbe changed completely for a different con-nection or protocol. It will thus be possibleto move to future communication proto-cols like popular Ethernet-based protocolswith ease.

USB interface

There is an USB interface on the front ofthe relay. All the relay functions can beset using a PC and DIGSI 4 protectionoperation program. Commissioning toolsand fault analysis are built into the DIGSIprogram and are used through this inter-face.

Interfaces

A number of communication modulessuitable for various applications can befitted at the bottom of the housing. Themodules can be easily replaced by the user.The interface modules support the follow-ing applications:

• System/service interfaceCommunication with a central controlsystem takes place through this interface.Radial or ring type station bus topologiescan be configured depending on the cho-sen interface. Furthermore, the units canexchange data through this interface viaEthernet and the IEC 61850 protocol andcan also be accessed using DIGSI.

• Ethernet interfaceThe Ethernet interface was implementedfor access to a number of protection unitsusing DIGSI.

System interface protocols (retrofittable)

IEC 61850 protocol

Since 2004, the Ethernet-based IEC 61850protocol is a global standard for protectionand control systems used by power utili-ties. Siemens was the first manufacturer toimplement this standard. This protocolmakes peer-to-peer communication possi-ble. It is thus possible to set up masterlesssystems to perform interlocking or transferschemes. Configuration is done usingDIGSI.

IEC 60870-5-103 protocol

The IEC 60870-5-103 protocol is an inter-national standard for the transmission ofprotective data and fault recordings. Allmessages from the unit and also controlcommands can be transferred by means ofpublished, Siemens-specific extensions tothe protocol.

PROFIBUS-DP protocol

PROFIBUS-DP is a widespread protocolin industrial automation. ThroughPROFIBUS-DP, SIPROTEC units maketheir information available to a SIMATICcontroller or receive commands from acentral SIMATIC controller or PLC.Measured values can also be transferredto a PLC master.

MODBUS RTU protocol

This simple, serial protocol is mainlyused in industry and by power utilities, andis supported by a number of relay manu-facturers. SIPROTEC units function asMODBUS slaves, making their informa-tion available to a master or receiving in-formation from it. A time-stamped eventlist is available.

DNP 3.0 protocol

Power utilities use the serial DNP 3.0 (Dis-tributed Network Protocol) for the stationand network control levels. SIPROTECunits function as DNP slaves, supplyingtheir information to a master system orreceiving information from it.

System solutions for protection and stationcontrol

Units featuring IEC 60870-5-103 interfacescan be connected to SICAM in parallel viathe RS485 bus or radially by fiber-opticlink. Through this interface, the system isopen for the connection to other manufac-turer systems (see Fig. 5).

Because of the standardized interfaces,SIPROTEC units can also be integratedinto systems of other manufacturers or inSIMATIC. Electrical RS485 or optical in-terfaces are available. The best physicaldata transfer medium can be chosen thanksto opto-electrical converters. Thus, theRS485 bus allows low-cost wiring in thecubicles and an interference-free opticalconnection to the master can be estab-lished.

For IEC 61850, an interoperable systemsolution is offered with SICAM. Throughthe 100 Mbits/s Ethernet bus, the units arelinked with SICAM electrically or opticallyto the station PC. The interface is standard-ized, thus also enabling direct connectionto relays of other manufacturers and intothe Ethernet bus. With IEC 61850, how-ever, the relays can also be used in othermanufacturers’ systems (see Fig. 6).
