ABB SYNCHROTACT ® 5 Synchronizing and Paralleling Equipment and Systems

DESCRIPTION

SYNCHROTACT® 5 is the fifth generation of synchronizing equipment produced by ABB Switzerland Ltd in Switzerland. SYNCHROTACT products from ABB are used for automatic synchronization of generators with power lines and for paralleling of synchronous lines. They are designed for fully automatic operation by dual-channel or single-channel systems.

SYNCHROTACT 5 covers the following areas of application:

1. Automatic synchronization and paralleling of generators with power lines

2. Automatic paralleling for synchronous and asynchronous lines and busbars

3. Monitoring (Synchrocheck) of automatic or manual paralleling of power lines, generators and voltage-free lines (dead bus)

Maximum safety in automatic and manual operation

The safety of the generator and network, while synchronizing, is the first requirement for such an equipment.

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. The first channel performs the automatic synchronization and the other one is an independent monitoring (Synchrocheck) of the first one. The hardware and software of each channel is designed by different development engineers using different microprocessors which 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.

Optimum availability

For higher availability of synchronizing equipment, the family range of SYNCHROTACT 5 offers various redundant configurations. See figures 6, 7 and 8. With those configurations both maximum safety and full availability is achieved.

The dual channel, automatic channel and single monitoring channel (Synchrocheck) systems are each provided in one casing. The redundant dual-channel system is in one casing, including interconnection wiring.

Special features

• Up to seven sets of parameter for seven different paralleling points can be stored in one device. 

• Freely-configurable digital inputs and outputs. 

• Operating with rated frequencies 50 Hz, 60 Hz and 16 2 /3 Hz. 

• For replacement of elder SYNCHROTACT systems or synchronization units made by other manufacturers.

Lower engineering costs

• Fewer auxiliary relays are required because the output contacts can carry higher currents. All I/Os are isolated. 

• No separate power supply unit is required. 

• A prefabricated unit is available for the selection of several paralleling points (SYN 5500) 

• Much of the cabling is rendered unnecessary through integration in a bus control system (MODBUS, Profibus etc.).

Fast commissioning

• A user-friendly software called “SynView” allows simple and fast commissioning of a SYNCHROTACT 5 system. 

• The SynView program recommends a value for each parameter and indicates minimum, maximum and default value for each parameter. 

• The system includes an intelligent program, which after interaction with the generator, can recommend values for certain parameters that are dependent on the power system’s circuit breaker, voltage regulator and speed governor. 

• The commissioning of SYNCHROTACT 5 can also be comfortably performed without a PC, using the controls on the front panel of the casing.

Easy integration in superimposed control system

SYNCHROTACT 5 can be easily integrated in a modern bus control system. The communication interface supports 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.
