Problems related to power control of low power-output steam turbines are analyzed. These turbines are designed to operate in distributed power generation systems. Principles of automatic control involving a single control valve are presented on the basis of experience gathered with high power-output turbines. Results of simulations of power control for a low power-output turbine are discussed. It has been proven that closing of the control system and an application of a power controller (of optimally selected parameters) improves the object dynamics (shortening of the transition period). At the same time, a lack of such optimization can results in occurrence of undesirable phenomena such as: overshoot in the generator power characteristics, elongation of the response time to disturbance or overshoot of turbine control valves.
