2 Functional principle

2.1 Brief descriptionThe digital synchronizing device SYNCHROTACT 5 is used as Synchrocheck formonitoring of automatic or manual paralleling of generators with lines as well as for theparalleling of already synchronized lines. The device is designed for system frequenciesof either 50/60 Hz or 16 2/3 Hz.

The setting values are entered via the keys provided on the front side of the device.

2.2 Paralleling functionsThe paralleling process can basically be divided into four function blocks:1. Measuring2. Voltage and frequency matching3. Monitoring of paralleling conditions4. Paralleling command generation

The functions measuring and monitoring of the paralleling conditions are both integratedin the application of the Synchrocheck.

2.2.1 MeasuringThe following measured variables are generated from the two single-phase measuringvoltages:Voltage U1, U2U1 is the reference voltage e.g. lineU2 sit the adjustable voltage e.g. generator.Frequency f1, f2f1 is the reference frequencyf2 is the adjustable frequency.Voltage difference UU = IU1I IU2IU > 0 Adjustable voltage is lowerU < 0 Adjustable voltage is higherSlip s

The signal for the amplitude value is formed from this byconversion and filtering . For zero-passage detection, the signal is filtered and passedthrough a comparator. The signals prepared in this way are passed to the processor viathe A/D converter.

2.2.2 Monitoring of paralleling conditionsThe monitoring of the paralleling conditions can be divided into these parallel-functioningblocks: voltage-carrying lines no-voltage lines

Paralleling of two voltage-carrying linesThe monitoring of the paralleling conditions enables a paralleling command (CHKRELEASE) if the following conditions are fulfilled simultaneously: the phase-angle difference is within the tolerance band the slip is within the tolerance band the voltage difference is within the tolerance band

Paralleling of no-voltage lines (dead bus)A special case for the monitoring is the paralleling of no-voltage lines. A parallelingcommand release is only issued if the external release signal is active.

The monitoring issues the paralleling command if the following conditions are fulfilledsimultaneously: the releasing signal for dead bus (digital input) is issued the zero voltage(s) does not exceed the set threshold U0max

2.3 Sequences of the synchronization processThe software is initialised after switching on the auxiliary voltage and immediatelyafterwards the synchronizing process is started. The device begins issuing theparalleling command release as soon as, and as long as the paralleling conditions arefulfilled.

The synchronizing process can be interrupted by disconnecting the auxiliary voltage.Since the device has only a monitoring function as a Synchrocheck, the synchronizingprocess can remain in operation.

2.4 Self-monitoring of the synchronizerExtensive monitoring includes the following functions:

2.4.1 Hardware monitoringAuxiliary voltage: The internally stabilised (reference) voltages are monitored. In theevent of inadmissible deviations, the device is immediately blocked.

Paralleling command circuit: Contact monitoring is provided by means of forciblyguided contacts (normally closed = NC) on the command releasing relay. The deviceshould be controlled in such a way that the switching on the auxiliary voltage as well asthe command issuing circuit is only possible by closed NC contacts.




2.4.2 Software monitoringThe program sequence is interrupted and reset by the internal watchdog, if an erroroccurs. After reset, it is again started automatically. This starting procedure is carried outthree times, afterwards the device is totally blocked.

2.5 Stored dataThe parameter values are permanently stored in a non-volatile memory, and are notaffected by ageing or failure of the auxiliary voltage. The parameter settings can only bechanged by means of write commands.

4.1 Parameter tableParametersNo. Parameter name Symbol Range/resolution Unit Default setting1. Slip limit smax 0.1 to 2.0 % 0.52. Angle limit max 5 to 40/5 DEG 153. Maximum

voltage differenceUmax 5 to 40/5 % 5

4. Maximum zero voltage U0max 0 to 50/5 % 505. Nominal voltage Un 50 to 130/5 VAC 110

4.2 Parameter settingsNominal voltage UnThe nominal voltage is set in volts. The nominal voltage is plant-dependent. It is typically58 (100/ 3 ); 64 (110/ 3 ); 100; 110 VAC, but can also have a different value.

Slip limit smaxThe setting value is based on different criteria, depending on the application:a) normal synchronizationb) paralleling of synchronous linesc) paralleling of asynchronous linesa) Normal synchronizationThe slip limit values set in practice are far from placing a serious load on the machine,even in large machines. Usual setting values in synchrocheck operation for monitoringof a manual paralleling: 0.1 to 0.3 %. For monitoring of automatic paralleling: larger thanthe limiting value of the automatic device. Default setting: 0.5 %The following are a number of points which can influence the setting value: Smaller slip limits should be chosen for large and modern generators. Gas turbines are more sensitive than hydrogenerators. Lower values should be selected if fine synchronization has priority and higher

values if fast synchronization is to take place. Lower slip values are usually selected where settings are made for synchrocheck

operation to monitor manual synchronizing.

b) Paralleling of synchronous linesIf only synchronous sources are paralleled, the slip limits do not need to be set




c) Paralleling of asynchronous lines:If two lines do not form a ring connection, the slip limits are restricted by the currentlimit permitted after paralleling. If the flow of power in a particular direction is to beavoided, the corresponding slip limit must be set to zero .

Angle limit maxThe permissible angle limit is based on different criteria, depending on the application:a) paralleling of asynchronous sources.b) paralleling of synchronous sources.a) Paralleling of asynchronous sources:If 3,6*fn*smax*t+3 > 10 DEG (t = closing time of the circuit breaker), the value should berounded up to whole degrees. Setting values above 15 DEG are not usual. If thecalculation produces such a result, it should be checked whether the maximum slip canbe reduced. For monitoring of automatic paralleling: larger than the limiting value of theautomatic device.

b) Paralleling of synchronous sources:The coupling reactance xK in ring mains lines and the balancing current IK flowingthrough these cause a phase shift between the two voltages U1 and U2.

5 Engineering instructions

5.1 General advice

5.1.1 Cable connectionsCables or wires with cross sections of 0.4 mm2 to 2.5 mm2 can be connected to all theconnection terminals. It is recommended that 1 mm2 should be used for control circuitsand power supply connections; at least 1,5 mm2 should be used for measuring circuits.Connection of more than one cable to a terminal is not permitted.

The casing must be connected with the earth potential via the connection provided forthis purpose.

In order to prevent polarity errors, marked cables should be used for all voltagetransformers (measuring circuits).

5.1.2 Recommended measures for long distancesFor distances >50 m, the following measures are recommended: The cables for the actual value measurement should have a cross section 2.5 mm2

and should be twisted or shielded. The control circuits should be operated with a nominal voltage of 125 VDC in order

to prevent inductive interference. All cables must be laid separately from high-voltage and high-current cables.

5.2 Sequences of the synchronizing processSwitching on the paralleling point: measuring voltage, auxiliary voltage and commandcircuit are all switched-on on the device.

The normally closed contact of the paralleling command release relay is provided toavoid the switching on, if the command release issuing contact (normally open) is in aclosed status as a result of pre-occurred error (see also the schematic diagram).

Caution




6 Installation and disposalSYNCHROTACT 5 devices operate with in some cases dangerous voltages (>50 V),e.g. measuring inputs up to 170 VAC and relay outputs up to 250 VAC/VDC.Manipulations carried out on these parts can cause death or injury to the personsinvolved or damage to surrounding objects. If handled correctly and in the properenvironment, as described in these instructions, there is no risk.

All relevant regulations must be observed during installation. It is essential that thesesafety regulations are read before starting any work on the SYNCHROTACT 5equipment.

The safe operation of the device requires appropriate transport and proper storage,erection and installation.

The equipment should be unpacked with the usual degree of care, without the use offorce and using suitable tools.

The device should be checked visually for any damage caused during transport. Anycomplaints of defects caused by improper transport should be addressed immediately tothe receiving station or the last carrier.

Only interior rooms which are dry and dust-free and which contain no gases, acid fumesor similar are suitable as sites for installation.

6.2 FixingSnap on the device on a top-hat rail. Check for the correct fitting.

6.3 Earthing and wiringThe casing must be connected with the earth potential via the connection provided forthis purpose.

The use of shielded cables is not necessary. If shielded cables are nonetheless used forprotection against high-frequency interference, it is recommended that the shielding beconnected to the earth potential at both ends over as wide an area as possible. If it isnot possible to earth the cables at both ends, one of the following procedures can betaken: Earthing of the shielding via a capacitor. The shielding is earthed directly at one end

and via a capacitor at the other end. Use of a double shielded cable: one of the two shields is earthed at one end, the

other at the other end.

6.4 DisposalThe inappropriate disposal of electrical equipment can lead to an environmental hazard.It is therefore important that electrical equipment be disposed of by qualified personnel.

The metallic casing, cover and front frame do not present any environmental risk andcan be recycled.

The circuit boards must be removed and should be disposed by a licensed disposalcompany. Environmentally harmful elements such as capacitors must be separated fromthe circuit boards.

The SYNCHROTACT 5 devices are environmentally friendly designed. The circuitboards are easy to remove.

8 Commissioning

8.1 Warnings and instructionsSYNCHROTACT 5 devices operate with in some cases dangerous voltages (>50 V),e.g. voltage transformer inputs up to 170 VAC and relay outputs up to 250 VAC/VDC.Manipulations carried out on these parts can cause death or injury to the personsinvolved or damage to surrounding objects. If handled correctly and in the properenvironment, as described in these instructions, there is no risk.

All relevant regulations must be observed during commissioning. It is essential thatthese safety regulations are read before starting any work on the SYNCHROTACT 5equipment.

After the device has been switched off, it must be ensured, by measuring, that nomeasuring voltages or control voltages >50 V are present at the terminals beforeanything is done to the device itself, e.g. unplugging the connector to replace the device.In order to prevent open voltage circuits being accidentally closed by third parties, thecircuits in question should be marked at the disconnection point (e.g. with a warningsign).If work is being carried out in the environment of the SYNCHROTACT 5, e.g. on therelay controls, electronics power supply, synchronizing instruments, all voltages greaterthan 50 V which are connected to the system must be switched off.

Before switching on, always check whether all connectors are plugged in.

The device may only be opened by qualified personnel. It is essential that ESDregulations are complied with.

8.2 Work carried out with the machine at a standstill

8.2.1 Wiring checkThe casing must be connected with the earth potential via the connection provided forthis purpose. All electrical connections must be checked against the system schematic(connection point and cross section).

8.2.2 First power-upInterrupt paralleling circuit(s): Bring the machine circuit breaker or circuit breaker to Testposition, draw out the carriage or pull command relay.

Switch on auxiliary voltage. All the elements light up on the LED-display. The the pointat the bottom right blinks.

Caution




8.2.3 Pre-setting of parametersInstructions on the correct use of the service control panel can be found in section 7Operating instructions. Advice on the parameter settings can be found in section 4.2Parameter settings.

Some parameter settings can already be determined and set while the machine is at astandstill: Un, smax, max, Umax, U0max.

Each single parameter setting after its modification must be confirmed within 30 s. If thisrule is not complied with, the old value remains in the memory.

8.2.4 Comparison of measuring points and switching pointsIf there are several paralleling points, it is essential to check whether the parallelingcommand and the measuring circuits (both) go to the same circuit breaker.

8.2.5 Test of the phase sequence and tuning of the measuring voltagesThe following tasks are the most important ones during the entire commissioning.They don't concern the synchronization device itself, but their right connectionsat the measuring voltages. In case of ignorance, damages may be caused to theplant!

It is a prerequisite for the following work and for the correct functioning of thesynchronization that the nominal voltage Un is set.

When disconnecting high voltage cables, it is essential that the correspondingregulations on working on high voltage installations are complied with.

Bring the circuit breaker to operating position so that it can be operated manually.

Caution




Closing the CB: Isolate one voltage source: open either isolator on generator side or star point

isolator or isolator on busbar side The other voltage source must be connected Close circuit breaker

The three LEDs U < Umax, s < smax, < max must light up now, in particular thelast one. Otherwise, either the measuring cables are incorrectly connected (in terms ofpolarity) or there is a phase shift.Incorrect polarity cannot be detected by the synchronizer. Paralleling with incorrectpolarity can lead to serious damage.

The synchronizing instruments (double voltmeter, double frequency meter andsynchroscope) if present, must be checked. The synchronoscope must stand at twelveoclock!

If this is not the case, the measuring circuits must be checked.

If the synchronoscope stands at six oclock, one voltage has been incorrectlyconnected. In other positions, either measuring is being carried out on incorrect phasesor a phase shift caused by the connection group of a step-up transformer has not beencompensated.

The circuit breaker should be opened again (or brought into test position) and theparalleling circuit interrupted.

If it is not possible to test the phase sequence as described above, it is still essential totest the measuring circuits. For example, the phase positions can be tested using highvoltage measuring sensors.

8.3 Work carried out while the machine is running

8.3.1 Function testsChecking the parallelingAt the end of commissioning, blind synchronization should be carried out several times(circuit breaker in Test position). The differential voltage and the paralleling commandshould thereby be recorded using a transient recorder. At the same time, thesynchronizing process should be observed using the synchronizing instruments in theplant.

Bring circuit breaker to operating position, adjust voltage and frequency and carry outlive synchronization. Record the synchronizing process.

9 Maintenance and faults

9.1 MaintenanceSYNCHROTACT 5 does not require any maintenance. In order to detect faults in goodtime before use, test synchronizing is recommended (external test circuit). However, themachine must be available for this purpose.

9.2 Faults

9.2.1 GeneralSYNCHROTACT 5 devices operate with in some cases dangerous voltages (>50 V),e.g. voltage transformer inputs up to 170 VAC and relay outputs up to 250 VAC/VDC.Manipulations carried out on these parts can cause death or injury to the personsinvolved or damage to surrounding objects. If handled correctly and in the properenvironment, as described in these instructions, there is no risk.

All relevant regulations must be observed during fault-rectification. It is essential thatthese safety regulations are read before starting any work on the SYNCHROTACT 5equipment.

If work is being carried out in the environment of the SYNCHROTACT 5, e.g. on therelay controls, electronics power supply, synchronizing instruments, all voltages greaterthan 50 V which are connected to the system must be switched off. In order to preventopen voltage circuits being accidentally closed by third parties, the circuits in questionshould be marked at the disconnection point (e.g. with a warning sign).Before switching on again, all connectors must always be plugged in.

9.2.2 TroubleshootingFirst of all it is important to ensure that the cabling of the synchronizing device is ok,prior to sending the device (in vain) for repair.In order to interpret a fault more accurately, it is important to make a distinction as towhich phase the synchronizer is currently in:1. System testing2. Commissioning3. Operation

System testing Is the wiring correct? Does the test method correspond to reality?

CommissioningFaults which occur during commissioning often have their cause in incorrect handling,incorrect settings, inadmissible external conditions or connection errors at the interfacebetween plant and synchronizing system.

Caution




The simplest way to check the synchronization is using the synchronoscope.

If it seems that the SYNCHROTACT should really have acted by now, you should checkwhich conditions could not be fulfilled. This can be seen simply from the LEDsU < Umax, s < smax and < max. All three conditions must always be fulfilled(LEDs lit), in order for a command release to be issued.Some governors do not operate in a very stable manner. The set tolerance band for theslip can often not be achieved for a long time, or not at all. In this case the problem maybe remedied by increasing the smax settings. However, you should not go beyond theusual values of 0.1 to 0.3 % without making sure that the machine can withstand this(see section 4.2).Following commissioning (operation)In this case, setting errors can usually be ruled out. It should be considered whether anychanges were made to the plant prior to the failed synchronization which could affect thesynchronizing process.

Otherwise, poor contacts, dropped connections, malfunctioning relays or tripped fusesmay be the cause.

9.2.3 Fault rectification

Replacing a SYNCHROTACT 5If a device is replaced, the circuit breaker must be set to test position or its commandcircuit must be interrupted to ensure that it can no longer be actuated.

1. Switch off SYNCHROTACT 5 and isolate all voltages which are still present from theSYNCHROTACT 5

It must be ensured, by measuring, that no measuring voltages or control voltages >50 Vare present at the terminals before anything is done to the device itself .

2. Connectors: loosen screws and unplug connectors

3. Press the device down, then tilt up and remove.

The replacement unit is installed in the reverse order. The commissioning and functioncheck of the replacement unit is carried out as described in the section onCommissioning. As soon as the settings are known, these can be used (refer to settingsrecord).Sending the device in for repairIf it has been definitely established that the synchronizer is defective, it must be sent infor repair. In order to guarantee that repairs proceed smoothly, it is essential that thequestionnaire at the end of the document is filled in and sent to the responsible ABBdepartment together with a copy of the settings record and the device.
