Steam Turbine Generator Controls

Steam turbine generator controls are used to control the speed, active power, voltage and reactive power of generators to 600 MW. 24 Si-TEC 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 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 CGC controllers are available with a variety of fuelling actuator outputs.

Product description

Steam Turbine Control Si-TEC BDG

The Si-TEC BDG (Basic Digital Governor) is a steam turbine control specially designed for mechanical drive applications (i.e. pumps, fans, shredders, mills, etc.). The BDG design is based on the very successful Si-TEC Xtend ADG steam turbine controller. The compact design, user friendly interface, onboard data logging and wide range of PIDs makes the BDG a standard choice for steam turbine control solutions.

Hydraulic amplifiers

The HA series Hydraulic Amplifiers from HEINZMANN Australia provide the force to operate heavy control valves of steam turbines or fuel control linkages of large reciprocating engines. This may be done via a mechanical input (i.e. HEINZMANN all electric actuator) or via a 0 – 200 mA input signal to the built in internal actuator. Our amplifiers are characterised by minimal overshoot, iron casing cast and billet power piston & output shaft. The output shaft supports bush (oil fed). Anti-wear coating is designed for longer service life.

HEINZMANN Australia offers a cost effective direct “bolt-on” replacement for Woodward 5¼” and 7¼” hydraulic amplifiers.
