ABB Powerful excitation systems, static starters and synchronizers

Around the generator solutions

The excitation system and synchronizer have a powerful impact on the

dynamic performance and the availability of the generator. They guarantee

the quality of the generator voltage and reactive power and therefore the

quality of the delivered energy from the power plant.

Compact automatic voltage regulator systems

The UNITROL® 1000 product family covers a wide range of

applications for voltage regulation tasks of a synchronous/

generator or motor up to 80 MVA. It sets a new benchmark

for the global industry with respect to functionality, reliability

and connectivity.

Small and medium Excitation and Automatic Voltage

Regulation system (AVR)

The UNITROL® 6000 Medium excitation systems are engineered

to meet individual operational and environmental conditions as

well as international and local standards.

MEGADRIVE-LCI drives and static starters

For more than 35 years ABB’s MEGADRIVE-LCI drives and static

starters have proven their maximum reliability and availability in

a wide range of industries and applications. The MEGADRIVE

LCI is the preferred choice when it comes to reliable and

efficient operation of gas-fire power plants.

Flexible automatic synchronizers

For over 50 years, SYNCHROTACT® has protected power plant

generators and substations from the potentially destructive

effects of current surges caused by paralleling in non

synchronized conditions. SYNCHROTACT 6 is the sixth

generation of this well-proven and popular technology. Over

22.000 SYNCHROTACT units have been sold since its

introduction, more than any other synchronizer on the market.
