Used to control the speed, active power, voltage and reactive power of generators to 50 MW. 24 Si-TEC Xtend modules may be connected to a standard Si-TEC LAN system. For control of a single generator, or one controller per generator in a Si-TEC Xtend system.
A standard system may comprise 24 units and split into 4 groups of generators catering for split bus/feeder system. Each group having the capability of operating as isolated isochronous or utility grid-paralleled systems. Re-synchronising of split bus/feeders and soft load transfer can be conducted using the Si-TEC GSM master module(s). Systems may be expanded to over 500 modules and 80 groups. The Si-TEC Xtend CGC controllers are available with a variety of fuelling actuator outputs.
