Steam Turbine Generator Controls - HEINZMANN Australia

HEINZMANN Australia

Optimal control technology for steam turbines

Steam turbine generator controls are used to control the speed, active power, voltage and reactive power of generators to 600 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.
