Abstract
A combined cycle electric power plant includes gas and steam turbines and steam generators and a digital/analog control system. A gas turbine megawatt load control system is included in the control and it includes a feedforward load control which generates a fuel reference equal to the sum of a megawatt load demand and an idle speed fuel demand. The megawatt load control also includes a feedback load trimmer which provides minor corrective action on the operation of the feedforward load control. Gas turbine and combined cycle plant operation results in the generation of megawatts equal to an input demand value.
