System integration

The 6MD66 bay control unitfrom the SIPROTEC 4 rangeare integrated components ofthe energy automation systemSICAM. Thus they are in thesame range as SiemensSIPROTEC 4 protection units.Bay control units and protec-tion relays are configured usingthe same tool, DIGSI 4. Bymeans of an automated com-parison, the configuration dataof the control level are trans-ferred to the configuration sys-tem, plusTOOLS, of thehigher-level master stationSICAM SAS, such that there isno need to enter informationtwice. All information (e.g. aswitching device with feed-back) from a bay control unit isclearly evident in plusTOOLSwith those names with whichit was entered in DIGSI, andcan be further processedthere.

With the concept of communi-cation connections via modularplug-in cards, the 6MD66 baycontrol units are open to allsorts of communication proto-cols. Currently, connection tothe energy automation systemSICAM is effected viaPROFIBUS. With this it is pos-sible to select whether com-munication is implemented viaan electrical RS485 connec-tion, an optical single ring or -for the highest availability re-quirements - an optical doublering. The two most often usedoptions are illustrated in Figs. 2and 3.Connection via an optical dou-ble ring circuit is recom-mended for use in high-voltageswitchgear: On one hand, thefiber-optic medium offers opti-mal transmission reliability cir-cuit in terms of electromag-netic interference, and on theother hand the double ringstructure provides failure pro-tection. Even if the ring is com-pletely cut through at onepoint, each bay control unit isstill connected to the masterstation.

Communication

Regarding communication be-tween components, particularemphasis is placed in theSIPROTEC 4 - SICAM systemon the functions required forenergy automation.• Every data item is time-

stamped at the source,i.e. where it originates.

• Information is marked ac-cording to where it origi-nates from (e.g. if a com-mand originates “local” or“remote”)

• The feedback to switchingprocesses is allocated to thecommands.

• Communication processesthe transfer of large datablocks, e.g. file transfers, in-dependently.

• For the reliable execution ofa command, the relevant sig-nal is first acknowledged inthe unit executing the com-mand. A check-back indica-tion is issued after the com-mand has been enabled (i.e.interlocking check, target =actual check) and executed.

In addition to the communica-tion interfaces on the rear ofthe unit, which are equipped tosuit the customer’s require-ments, the front includes anRS232 interface for connectionof DIGSI. This is used for quickdiagnostics as well as for theloading of parameters. DIGSI 4can read out and represent theentire status of the unit on-line,thus making diagnostics anddocumentation more conve-nient.It is in principle possible to im-plement other communicationprotocols upon request.

Control

The bay control units of the6MD66 series have commandoutputs and indication inputsthat are particularly suited tothe requirements of high-voltage technology. As an ex-ample, the 2-pole control of aswitchgear is illustrated (seeFig. 4).In this example, two poles ofthe circuit-breaker are closedand 1 pole is opened. All otherswitching devices (discon-nectors, earthing switches),are closed and opened in1½-pole control. A maximumof 14 switching devices can becontrolled in this manner.A complete 2-pole control of allswitching devices (see Fig. 5)is likewise possible. Howevermore contacts are required forthis. A maximum of 11 switch-ing devices can be controlledin this manner.

Synchronization

The bay control unit can, uponclosing of the circuit-breaker,check whether the synchroni-zation conditions of both partialnetworks are met(synchrocheck). Thus an addi-tional, external synchronizationdevice is not required. The syn-chronization conditions can beeasily specified using the con-figuration system DIGSI 4. Theunit differentiates betweensynchronous and asynchron-ous networks and reacts differ-ently upon connection:In synchronous networks thereare minor differences with re-gard to phase angle and volt-age moduli and so the cir-cuit-breaker response timedoes not need to be taken intoconsideration. For asynchron-ous networks however, thedifferences are larger and therange of the connection win-dow is traversed at a fasterrate. Therefore it is wise hereto take the circuit-breakerresponse time into consider-ation. The command is auto-matically dated in advance ofthis time so that the cir-cuit-breaker contacts close atprecisely the right time. Fig. 6illustrates the connection ofthe voltages.As is evident from Fig. 6, thesynchronization conditions aretested for one phase. The im-portant parameters for syn-chronization are:|Umin| < |U| < |Umax|(Voltage modulus)∆ϕ < ∆ϕmax(Angle difference)∆f < ∆fmax(Frequency difference)Using the automation func-tions available in the bay con-trol unit it is possible to con-nect various referencevoltages independent of thesetting of a disconnector. Thusin the case of a duplicatebusbar system, the referencevoltage of the active busbarcan be automatically used forsynchronization (see Fig. 7).Alternatively the selection ofthe reference voltage can alsotake place via relay switching,if the measurement inputs arealready being used for otherpurposes.

The bay control unit offers theoption of saving various param-eter sets (up to eight) for thesynchronization function and ofretaining these for operation.Thus the different properties ofseveral circuit-breakers can betaken into consideration.These are then used at the ap-propriate time. This is relevantif several circuit-breakers withe.g. different response timesare to be served by one baycontrol unit.The measured values can beconnected to the bay controlunit in accordance with Fig. 6(single-phase system) or Fig. 8(two-wattmeter circuit).

SIPROTEC 46MD66 Bay Control Unit

Switchgear interlockings

Using the CFC (ContinuousFunction Chart) available in allSIPROTEC 4 units, the bay in-terlock conditions can amongother things be convenientlyconfigured graphically in the6MD66 bay control unit. Thecross-bay interlock conditionsare normally checked in thehigher-level station control unitSICAM SC. To this end, how-ever, the new function”inter-relay communication”(see next section) can also beapplied.In the tests prior to commandoutput, the positions of bothkey-operated switches are alsotaken into consideration. Theupper key-operated switch cor-responds to the S5 function(local/remote switch), which isalready familiar from the 8TKswitchgear interlock system.The lower key-operated switcheffects the changeover to non-interlocked command output(S1 function). In the position”Interlocking Off” the key can-not be withdrawn, with the re-sult that non-operation of theconfigured interlocks is imme-diately evident.The precise action of the key-operated switch can be set us-ing the parameter ”switchingauthority”.With the integrated function”switchgear interlocking”there is no need for an externalswitchgear interlock device.Furthermore, the followingtests are implemented(parameterizable) before theoutput of a command:• Target = Actual, i.e. is the

switching device already inthe desired position?

• Double command lockcut,i.e. is another command al-ready running?

• Individual commands, e.g.earthing control canadditionally be secured usinga code.

Inter-relay communication

The new function ”inter-relaycommunication” enables theexchange of information be-tween the bay control unitswithout the intervention of theSICAM SAS master station be-ing required. To this end, theunits are connected to eachother via a RS485 connectionor via an external converterand a fiber optics transmissionsystem (see Figs. 13 and 14).

One situation where inter-relaycommunication comes intoplay are the interlock condi-tions within a bay featuring the1½ circuit-breaker method,which is operated using threebay control units (see Fig. 15).With the 1½ circuit-breakermethod, a bay control unit is al-located to every circuit-breaker. As a result, the redun-dancy on the primary side(even if one circuit-breakerfails, both feeders still have tobe supplied) is also supportedby a redundancy on the sec-ondary (control) side. Controlover the entire bay is retained,even if one of the bay controlunits fails. If the connection tothe master unit or the masterunit itself is disturbed, controlis still possible with the inter-locking in operation, by meansof the inter-relay communica-tion.Inter-relay communication islikewise configured usingDIGSI 4. To this end a networkof units is created, which pro-vides a logic matrix. The infor-mation which the stations areto exchange is assigned in thislogic matrix (see Fig. 16).As is illustrated in Fig. 16 theinformation from the coupling(6MD664 unit IGK2 coupling) isavailable for use in the feeder(assignment to 6MD663 unitIGK1 feeder as target). In thisway, the information from thefeeder unit can be used in thecoupling unit.The connection matrix con-tains all information which hasinter-relay communication asthe source or the target (newcolumn ”O”), in the knownDIGSI 4 configuration matrix.

The connection of the inputchannels can be chosen with-out restriction. For the two-wattmeter circuit, the interfaceconnection should be selectedin accordance with Fig. 18. Thetwo-wattmeter circuit enablesthe complete calculation of athree-phase system with onlytwo voltage and two currenttransformers.

Metered values

For internal metering, the unitcan calculate an energy me-tered value from the measuredcurrent and voltage values. Ifan external meter with a me-tering pulse output is available,the bay control unit can obtainand process metering pulsesvia an indication input.The metered values can bedisplayed and passed on to amaster unit. A distinction ismade between forward, re-verse, active and reactivepower (± kWh, ± kvarh).

Automation

With integrated logic, the usercan set, via a graphic interface(CFC, Continuous FunctionChart), specific functions forthe automation of switchgearor substation. Functions areactivated via function keys, bi-nary input or via communica-tion interface. Processing of in-ternal indications or measuredvalues is also possible.

Switching authorization/Key-operated switch

The switching authorization(control authorization)(interlocked/non-interlocked,corresponds to key-operatedS1 in the 8TK interlock system)and the switching authority (lo-cal/remote, corresponds tokey-operated S5 for 8TK) canbe preset for the SIPROTEC 4bay control unit usingkey-operated switches. Theposition of both keys is auto-matically evaluated by com-mand processing. The key foroperation without interlockscannot be removed when inthe position “non-interlocked”,such that this mode of opera-tion is immediately recogniz-able (see also page 8, Section”Switchgear interlockings”).Every change in thekey-operated switch positionsis logged.

Chatter blocking

Chatter blocking feature evalu-ates whether, in a configuredperiod of time, the number ofstatus changes of indication in-put exceeds a specified figure.If exceeded, the indication in-put is blocked for a certain pe-riod, so that the communica-tion line to the master unit willnot be overloaded by disturbedinputs.For every binary input, it is pos-sible to set separately whetherthe chatter blocking should beactive or not. The parameters(number of status changes,test time, etc.) can be set onceper unit.

Indication / measured valueblocking

To avoid the transmission of in-formation to the master unitduring works on the bay, atransmission blocking can beactivated.

Indication filtering

Indications can be filtered anddelayed.Filtering serves to suppressbrief changes in potential atthe indication input. The indica-tion is passed on only if the in-dication voltage is still presentafter a set period of time.The filter time can be set from0 to 24 hours in 1 ms steps. Itis also possible to set the filtertime so that it can, if desired,be retriggered.Furthermore, the hardware fil-ter time can be taken into con-sideration in the time stamp;i.e. the time stamp of a mes-sage that is detected as arriv-ing will be predated by theknown, constant hardware fil-ter time. This can be set indi-vidually for every message in a6MD66 bay control unit.

Time management

The 6MD66 bay control unitscan, like the other units in theSIPROTEC 4 range, be pro-vided with the current time bya number of different meth-ods:• Via the interface to the

higher-level system control(PROFIBUS FMS)

• Via the external time syn-chronization interface on therear of the unit (various pro-tocols such as IRIG B andDCF77 are possible)

• Via external minute impulse,assigned to a binary input

• From another bay controlunit by means of inter-relaycommunication

• Via the internal unit clock.Fig. 19 illustrates the settingsthat are possible on the DIGSIinterface.

The PC program DIGSI 4 isused for the convenient config-uration of all SIPROTEC 4units. Data exchange with theconfiguration tool plusTOOLSof the energy automation sys-tem SICAM is possible, suchthat the bay level informationneed only be entered once.Thus errors that could arise asa result of duplicated entriesare excluded.

DIGSI 4 offers the user a mod-ern and intuitive Windows in-terface, with which the unitscan be set and also read out.

DIGSI 4 configuration matrix

The DIGSI 4 configuration ma-trix allows the user to see theoverall view of the unit config-uration at a glance (see Fig.21). For example, all allocationsof the binary inputs, the outputrelays and the LEDs are shownat a glance.. And with one clickof the button connections canbe switched.Also the measuring and meter-ing values are contained in thismatrix.

Commissioning

Special attention has been paidto commissioning. All binary in-puts and outputs can be readand set directly. This can sim-plify the wire checking processsignificantly for the user.

CFC: Reduced time and plan-ning for programming logic

With the help of the CFC (Con-tinuous Function Chart), youcan configure interlocks andswitching sequences simplyby drawing the logic se-quences; no special knowl-edge of software is required.Logical elements, such asAND, OR and time elements,measured limit values, etc. areavailable.

Operationalmeasured values (analog val-ues) in the unit can be placedwhere required.In order to also display thecomprehensive plant of thehigh-voltage switchgear andcontrolgear, the feeder controldisplay of the 6MD66 bay con-trol unit can have a number ofpages. In this process, severalpages of a control display canbe configured under one an-other, and the user can switchbetween them using the cur-sor. The number of pages, in-cluding the basic display andthe feeder control display,should not exceed 10, as oth-erwise the memory in the unitwill be completely occupied.
