12 /3Siemens SIP Edition No. 7

Description

The SIPROTEC 4 6MD61 IO-Box enables in a simple, easy wayto enhance the number of binary inputs and outputs in theswitchgear. It can be used directly in the bay together with otherSIPROTEC 4 units and also together with SICAM PAS to serve as acentral process connection.

The IO-Box is based on the SIPROTEC 6MD63 and 6MD66 series,so it can be easily integrated in systems with other SIPROTEC 4units.

The IO-Box supports a wide range of demand for additionalbinary inputs (BI) and binary outputs (BO), starting from20 BI+10 BO and going up to 80 BI+53 BO. All importantstandard communication protocols are supported.With IEC 61850-GOOSE communication, a direct informationinterchange with other SIPROTEC units is possible. For simpli-cation and cost reduction, the IO-Box is available only withoutautomation (CFC), without keypad and without display.

Substation Automation / 6MD61Application

12 /4 Siemens SIP Edition No. 7

Application

The following gures show the mostimportant applications of the SIPROTECIO-Box 6MD61.

The conguration shown in Fig. 12/2allows direct GOOSE communicationbetween the SIPROTEC 4 units (6MD66,7SJ63) and the IO-Boxes, independentof the substation controller. Of course,this conguration is also possible withoutsubstation controller. The IO-Box isused as additional digital inputs andmeasurements (measurements only with6MD612), and serves as an additionalcommand output.

The communication between IO-Box andthe substation controller is established byusing the IEC 61850 standard protocol.

Fig. 12/3 shows a conguration in whichthe IO-Box is used as a central processconnection in the cubicle of the substa-tion controller. For example, cubiclesignaling lamps or a signaling horn arecontrolled by the command relays of theIO-Box.

Fig. 12/4 shows the communication forsubstations with no Ethernet protocolused. In this case, all communication linesgo directly to the substation controller.If information from the IO-Box is used forswitchgear interlocking, the interlocking

logic must be part of the substationcontroller.

Substation Automation / 6MD63SIPROTEC 4 6MD63 bay control unit


Description

The 6MD63 bay control unit is a exible, easy-to-use controlunit. It is optimally tailored for medium-voltage applications butcan also be used in high-voltage substations.

The 6MD63 bay control unit has the same design (look and feel)as the other protection and combined units of the SIPROTEC 4relay series. Conguration is also performed in a standardizedway with the easy-to-use DIGSI 4 conguration tool .

For operation, a large graphic display with a keyboard is avail-able. The important operating actions are performed in a simpleand intuitive way, e.g. alarm list display or switchgear control.The operator panel can be mounted separately from the relay,if required. Thus, exibility with regard to the mounting positionof the unit is ensured.

Integrated key-operated switches control the switching authorityand authorization for switching without interlocking.

Substation Automation / 6MD66Application


Application

Communication

With regard to communication betweencomponents, particular emphasis isplaced on the SIPROTEC 4 functionsrequired for energy automation. Every data item is time-stamped at its

source, i.e. where it originates. Information is marked according to

where it originates from (e.g. if a com-mand originates local or remote)

The feedback to switching processes isallocated to the commands.

Communication processes the transferof large data blocks, e.g. le transfers,independently.

For the reliable execution of a

command, the relevant signal is rstacknowledged in the unit executingthe command. A check-back indicationis issued after the command has beenenabled (i.e. interlocking check, target= actual check) and executed.

In addition to the communication inter-faces on the rear of the unit, which areequipped to suit the customers require-ments, the front includes an RS232 inter-face for connection of DIGSI. This is usedfor quick diagnostics as well as for theloading of parameters. DIGSI 4 can readout and represent the entire status of the

unit online, thus making diagnostics anddocumentation more convenient.

Control

The bay control units of the 6MD66 serieshave command outputs and indicationinputs that are particularly suited to therequirements of high-voltage technology.As an example, the 2-pole control of aswitching device is illustrated (see Fig. 12/11). In this example,two poles of the circuit-breaker are closed and 1 pole is open. Allother switching devices (disconnectors, grounding switches) areclosed and open in 1-pole control. A maximum of 14 switchingdevices can be controlled in this manner.

A complete 2-pole control of all switching devices (seeFig. 12/12) is likewise possible. However more contacts arerequired for this. A maximum of 11 switching devices can becontrolled in this manner.

A possible method to connect the switching devices to the baycontrol unit 6MD66 is shown in Fig. 12/13. There it is shownhow three switching devices Q0, Q1, and Q2 are connectedusing 1 pole control.

Substation Automation / 6MD66Functions


Functions

Switchgear interlockings

Using the CFC (Continuous Function Chart) available in allSIPROTEC 4 units, the bay interlock conditions can, among otherthings, be conveniently congured graphically in the 6MD66 baycontrol unit. The inter-bay interlock conditions can be checkedvia the inter-relay communication (see next section) to other6MD66 devices. With the introduction of IEC 61850 communica-tion, the exchange of information for interlocking purposesis also possible via Ethernet. This is handled via the GOOSEmessage method. Possible partners are all other bay devices orprotection devices which supportIEC 61850- GOOSE message.

In the tests prior to command output, the positions of bothkey-operated switches are also taken into consideration. Theupper key-operated switch corresponds to the S5 function (local/remote switch), which is already familiar from the 8TK switch-gear interlock system. The lower key-operated switch effects the

changeover to non-interlocked command output (S1 function).In the position Interlocking Off the key cannot be withdrawn,with the result that non-operation of the congured interlocks isimmediately evident.

The precise action of the key-operated switch can be set usingthe parameter switching authority.

With the integrated function switchgear interlocking there isno need for an external switchgear interlock device.

Furthermore, the following tests are implemented (parameteriz-able) before the output of a command: Target = Actual, i.e. is the switching device already in the

desired position?

Double command lockout, i.e. is another command alreadyrunning? Individual commands, e.g. grounding control can additionally

be secured using a code.

Synchronization

The bay control unit can, upon closingof the circuit-breaker, check whether thesynchronization conditions of both par tialnetworks are met (synchro-check). Thusan additional, external synchronization

device is not required. The synchroniza-tion conditions can be easily speciedusing the conguration system DIGSI 4.The unit dif ferentiates between synchro-nous and asynchronous networks andreacts differently upon connection:

In synchronous networks there areminor differences with regard to phaseangle and voltage moduli and so thecircuit-breaker response time does notneed to be taken into consideration. Forasynchronous networks however, thedifferences are larger and the range of theconnection window is traversed at a fasterrate. Therefore it is wise here to take thecircuit-breaker response time into consid-eration. The command is automaticallydated in advance of this time so that thecircuit-breaker contacts close at preciselythe right time.

Fig. 12/14 illustrates the connection ofthe voltages.

As is evident from Fig. 12/14, the syn-chronization conditions are tested for onephase. The important parameters forsynchronization are:

|U min| < | U | < | U max|(Voltage modulus)

< max (Angle difference)

f < f max(Frequency difference)

Using the automation functions availablein the bay control unit, it is possibleto connect various reference voltagesdepending on the setting of a disconnec-tor. Thus in the case of a double busbarsystem, the reference voltage of theactive busbar can be automatically usedfor synchronization (see Fig. 12/15).

Alternatively the selection of the refer-ence voltage can also take place via relayswitching, if the measurement inputs arealready being used for other purposes.

Fig. 12/15 Voltage selection for synchronization with duplicate busbar system

Fig. 12/16 Simultaneous connection of measured values according to a two-wattmeter circuitand synchronization


17/33



Synchronization

The bay control unit offers the optionof storing various parameter sets (upto eight) for the synchronization func-tion and of selecting one of these foroperation. Thus the dif ferent properties

of several circuit- breakers can be takeninto consideration. These are then usedat the appropriate time. This is relevant ifseveral circuit-breakers with e.g. differentresponse times are to be served by onebay control unit.

The measured values can be connectedto the bay control unit in accordance withFig. 12/14 (single-phase system) orFig. 12/16 (two-wattmeter circuit).

The synchronization function can beparameterized via four tabs in DIGSI.

Substation Automation / 6MD66Communication


Communication

The device is not only able to communicateto the substation control level via standardprotocol like IEC 61850, IEC 60870-5-103or others. It is also possible to communi-

cate with other bay devices or protectiondevices. Two possibilities are available.

Inter-relay-communication

The function inter-relay-communicationenables the exchange of informationdirectly between 6MD66 bay controllerdevices. The communication is realizedvia Port C of the devices, so it is inde-pendent from the substation communica-tion port B. Port C is equipped with aRS485 interface. For communication overlonger distances, an external converter tober-optic cable can be used.

An application example for inter-relay-communication is shown in Fig. 12/22.Three 6MD66 devices are used for controlof a 1 circuit-breaker bay. One deviceis assigned to each of the three circuit-breakers. By this means, the redundancyof the primary equipment is also availableon the secondary side. Even if onecircuit-breaker fails, both feeders can besupplied. Control over the entire bay isretained, even if one bay control unit fails.The three bay control units use the inter-relay-communication for interchange ofswitchgear interlocking conditions. Sothe interlocking is working completelyindependent from the substation controllevel.

IEC 61850-GOOSE

With the communication standardIEC 61850, a similar function like inter-relay-communication is provided withthe GOOSE communication to otherIEC 61850-devices. Since the standardIEC 61850 is used by nearly all SIPROTECdevices and many devices from othersuppliers, the number of possiblecommunication partners is large.

The applications for IEC 61850-GOOSE arequite the same as for inter-relay-commu-nication. The most used application is theinterchange of switchgear interlockinginformation between bay devices. GOOSEuses the IEC 61850 substation Ethernet,so no separate communication port is needed.The congurationis shown in Fig. 12/23. The SIPROTEC devices are connectedvia optical Ethernet and grouped by voltage levels (110 kV and20 kV). The devices in the same voltage level can interchangethe substation-wide interlocking information. GOOSE uses thesubstation Ethernet.

Fig. 12/21 Typical application: 1 circuit-breaker method(disconnector and grounding switch not shown)

Fig. 12/22 Connection matrix of inter-relay communication in DIGSI 4

Fig. 12/23 Connection for IEC 61850-GOOSE communication

Like inter-relay-communication, GOOSE also supplies a statusinformation for supervision of the communication. In case ofinterruption, the respective information is marked as invalid.

Therefore, non-affected information still can be used for inter-locking, and a maximum functional availability is guaranteed.

Measured-value processing

Measured-value processing is imple-mented by predened function modules,which are likewise congured usingDIGSI 4.

The transducer modules are assigned inthe DIGSI 4 assignment matrix to currentand voltage channels of the bay controlunit. From these input variables, theyform various computation variables (seeTable 12/1).

The individual transducer modules can beactivated in the functional scope of theunit and will then appear in the DIGSI 4assignment matrix with the input chan-nels and output variables from Table 1.The output variables can then be assignedto the system interface or representedin the measured value window in thedisplay.

The connection of the input channels canbe chosen without restriction. For thetwo-wattmeter circuit, the interface con-nection should be selected in accordancewith Fig. 12/26. The two-wattmeter circuitenables the complete calculation of athree-phase system with only two voltageand two current transformers.

Metered values

For internal metering, the unit cancalculate an energy metered value fromthe measured current and voltage values.If an external meter with a metering pulseoutput is available, the bay control unitcan obtain and process metering pulsesvia an indication input.

The metered values can be displayed andpassed on to a master unit. A distinctionis made between forward, reverse, activeand reactive power ( kWh, kvarh).

Automation

With integrated logic, the user can set, via a graphic interface(CFC, Continuous Function Chart), specic functions for theautomation of switchgear or substation. Functions are activatedvia function keys, binary input or via communication interface.Processing of internal indications or measured values is alsopossible.

Switching authorization / key-operated switch

The switching authorization (control authorization) (interlocked/non-interlocked, corresponds to key-operated S1 in the 8TK

interlock system) and the switching authority (local/remote,corresponds to key-operated S5 for 8TK) can be preset for theSIPROTEC 4 bay control unit using key-operated switches. Theposition of both keys is automatically evaluated by commandprocessing. The key for operation without interlocks cannot beremoved when in the position non-interlocked, such that thismode of operation is immediately recognizable (see also page12/15, Section Switchgear interlockings).

Every change in the key-operated switch positions is logged.

Chatter blocking

Chatter blocking feature evaluates whether, in a conguredperiod of time, the number of status changes of indication inputexceeds a specied gure. If exceeded, the indication input isblocked for a certain period, so that the communication line tothe master unit will not be overloaded by disturbed inputs.

For every binary input, it is possible to set separately whetherthe chatter blocking should be active or not. The parameters(number of status changes, test time, etc.) can be set once perunit.

Fig. 12/26 Two-wattmeter circuit (connection to bay control unit)

Indication / measured value blocking

To avoid the transmission of information to the master unit dur-ing works on the bay, a transmission blocking can be activated.

Indication ltering

Indications can be ltered and delayed.

Filtering serves to suppress brief changes in potential at theindication input. The indication is passed on only if the indica-tion voltage is still present after a set period of time.The lter time can be set from 0 to 24 hours in 1 ms steps. It isalso possible to set the lter time so that it can, if desired, beretriggered.

Furthermore, the hardware lter time can be taken into consid-eration in the time stamp; i.e. the time stamp of a message thatis detected as arriving will be predated by the known, constanthardware lter time. This can be set individually for every binaryinput in a 6MD66 bay control unit.


21/33



Auto-reclosure (ANSI 79)

The 6MD66 is equipped with an auto-reclosure function (AR). The functionincludes several operating modes: Interaction with an external device

for auto-reclosure via binary inputsand binary outputs; also possible withinteraction via IEC 61850-GOOSE

Control of the internal AR function byexternal protection

Multiple-shot auto-reclosure Interaction with the internal synchro-check Monitoring of the circuit-breaker auxiliary contacts

In addition to the above-mentioned operating modes, severalother operating principles can be employed by means of theintegrated programmable logic (CFC). Integration of auto-reclosure in the feeder protection allows the line-side voltagesto be evaluated. A number of voltage-dependent supplementary

functions are thus available: DLC

By means of dead-line-check (DLC), reclosure is effected onlywhen the line is deenergized (prevention of asynchronousbreaker closure)

ADTThe adaptive dead time (ADT) is employed only if auto-reclosure at the remote station was successful (reduction ofstress on equipment).

RDTReduced dead time (RDT) is employed in conjunction withauto-reclosure where no teleprotection method is employed:When faults within the zone extension but external to the pro-

tected line of a distance protection are switched off for rapidauto-reclosure (RAR), the RDT function decides on the basis ofmeasurement of the return voltage from the remote stationwhich has not tripped whether or not to reduce the dead time.

Fig. 12/27 Parameterization of time management

Breaker failure protection (ANSI 50BF)

The 6MD66 incorporates a two-stage circuit-breaker failureprotection to detect failures of tripping command execution,for example, due to a defective circuit breaker. The currentdetection logic is phase-selective and can therefore also be usedin single-pole tripping schemes. lf the fault current is not inter-rupted after a settable time delay has expired, a retrip commandor a busbar t rip command will be generated. The breaker failureprotection can be initiated by external devices via binary inputsignals or IEC 61850 GOOSE messages.

Time management

The 6MD66 bay control units can, like the other units in theSIPROTEC 4 range, be provided with the current time by anumber of different methods: Via the interface to the higher-level system control

(PROFIBUS FMS or IEC 61850) Via the external time synchronization interface on the rear

of the unit (various protocols such as IRIG B and DCF77 arepossible)

Via external minute impulse, assigned to a binary input From another bay control unit by means of inter-relay

communication Via the internal unit clock.

Fig. 12/27 illustrates the settings that are possible on the DIGSIinterface.
