초록

A combined cycle electric power plant includes gas and steam turbines and steam generators and a digital/analog control system. An automatic digital portion of the control system includes a speed control which generates a speed error from the actual turbine speed and a turbine speed reference, and a proportional plus integral controller acts on the speed error to generate a fuel reference for the gas turbine fuel valve position controls after ignition and during wide range speed control. A speed reference generator includes a stored representation of spe...
