Application
SYNCHROTACT® 5 is the fifth generation of synchronizing equipment produced by ABB. SYNCHROTACT products are used for automatic synchronization of generators with power lines and for paralleling of synchronous lines. They are designed for fully automatic operation by dualchannel or single-channel systems.
Synchronizing equipment is used in power stations where a generator needs to be paralleled with a power line or in substations to parallel two synchronous lines. Power circuit breakers can only be closed if voltage at both ends is synchronous. Otherwise it will cause a disturbance in the power network, trip the breaker, shock the generator and unit transformer. In extreme cases, it can damage both.
SYNCHROTACT 5 guarantees a safe and reliable synchronization as a monitoring element for manual paralleling or as an independent fully-automatic synchronizing unit.
Safety and Availability
Thanks to its flexible design, SYNCHROTACT 5 can be used in many different configurations in order to ensure maximum safety and availability.
Definition
In synchronizing, the term “dual channel” applies to a configuration of two channels in series, where one channel blocks the faulty operation of the other. This configuration increases the safety of operation.
The term “redundancy” applies to a configuration of two devices in parallel. If one fails, the other one can take over the function. This configuration increases the availability of the synchronizing system.
Maximum safety in automatic and manual operation
The first requirement during synchronizing process is the safety of the generator and the network.
The safe automatic synchronization is guaranteed by a compact dual-channel system including two devices with independent hardware and software, which are connected in series (Fig. 4). The first channel performs the automatic synchronization and the other channel implements independent monitoring (Synchrocheck) of the first one. The hardware and software of each channel are designed by different development engineers using different microprocessors to protect the operation from any possible systematic failure.
The safe manual synchronization is ensured by a monitoring device (Synchrocheck), which is in series with the manual paralleling switch (Fig. 5). An automatic synchronizer may also be used as Synchrocheck for manual synchronization.
Optimum availability
The family range of SYNCHROTACT 5 offers various redundant configurations (Figures 6, 7 and 8) that ensure both maximum safety and full availability.
The dual channel, automatic channel and single monitoring channel (Synchrocheck) systems are each provided in one casing. This also applies to the redundant dual-channel system including interconnection wiring.

Functionality and Types
SYNCHROTACT 5 utilizes state-of-the-art hardware and software technology, which includes a fundamentally improved service and maintenance tool.
Special features
One device can store up to seven sets of parameters for seven different paralleling points
Freely configurable digital inputs and outputs •
Operating with rated frequencies 50 Hz, 60 Hz and 16 ²/ ³ Hz
For retrofit of previous SYNCHROTACT systems or • synchronization units of other manufacturers
Lower engineering costs
Output contacts can carry higher currents, thus fewer auxiliary relays required; all I/Os are isolated
Separate power supply unit is not required
Prefabricated unit is available for the selection of several paralleling points (SYN 5500)
Reduced cabling due to integration in a bus control system (IEC 61850, MODBUS, Profibus etc.)
Fast commissioning
User-friendly SynView software for simple and fast • commissioning
SynView software recommends parameter values and indicates min/max/default values for each parameter
The system includes an intelligent program, which after • interaction with the generator can recommend values for parameters that are dependent on the power system’s circuit breaker, voltage regulator and speed governor
SYNCHROTACT 5 commissioning can also be comfortably performed without a PC, using the controls on the front panel of the casing
Easy plant control integration, including IEC 61850
SYNCHROTACT 5 can be easily integrated in a modern bus control system. The communication interface supports IEC 61850 and the protocols MODBUS RTU, Profibus DP or LON-Bus.
At the same time, as a safety-relevant component, the synchronizing device remains an independent and protected module within the system.
Less travelling costs thanks to remote servicing
Another interface is provided for remote servicing. SYNCHROTACT 5 gets its own IP address, and communication is done via Ethernet interface with TCP/IP protocol. Thus SynView software can directly access the device via internet. The access can be switched on and off on the rear plate of the device.

SynView Software
SynView enables a simple and quick commissioning of Synchrotact 5 equipment. the software runs under Microsoft ® Windows™ 95, 98, 2000, nt or XP and has German, English or French language interfaces. the program can also be used during operation, for example to display the actual values in order to follow the synchronization progress
Main functions of SynView program
Parameters setting, using a simple and user-friendly parameter setting display
display of actual values, like Synchroscope, voltage and frequency with real-time data
Transient recorder displays the recorded data, thus a separate recorder during commissioning is not necessary
Event and error logging in clear text with time stamp for the last 256 events
Product Model Classification and Technical Parameters
SYNCHROTACT ® The 5 series includes 6 core models, each with clear positioning and differentiated parameter design, suitable for different installation scenarios and functional requirements:
(1) Model classification and core positioning
Model core positioning operation mode supports core application scenarios
SYN 5100 Synchrocheck only supports monitoring, in conjunction with manual parallel monitoring of small power stations and simple substations
SYN 5200 advanced function synchronization checker only supports monitoring, with more comprehensive functions for scenarios that require higher monitoring accuracy
SYN 5201 Single Channel Automatic Synchronization Equipment Automatic+Manual (Parallel) Hybrid Operation of Automatic/Manual for Small and Medium sized Power Plants
The SYN 5202 dual channel automatic synchronization system is mainly automatic and supports automatic synchronization of large power stations and hub substations through manual bypass
SYN 5302 redundant dual channel automatic synchronization system is fully automatic, supporting redundant switching between main power stations and core substations (high safety requirements)
SYN 5500 multi parallel point connection auxiliary equipment has no independent operation function, only auxiliary connections need to be connected to multiple parallel points for centralized control scenarios
