Steam turbines may be used as power turbine for compressors or, combined with a generator, for power generation. The steam may also be used as a constant-pressure source for diverse steam networks at different pressures, for chemical processes or for heating.
Steam turbine control has to meet multiple requirements, depending on the field of application. Next to automatic start/stop with optimized warm-up they may need stable pressure control for multiple extraction pressures, power control or speed control for generator operation.
