ABSTRACT:
A combined cycle power plant includes gas and steam turbines, gas turbine afterburners, steam generators, and a digital/analog control system. A megawatt load control system varies a fuel control signal to govern a detected power output according to a reference value, the fuel control signal determining the flow rate of fuel to a gas turbine. An afterburner is connected to heat the exhaust gas from the gas turbine. Both the gas turbine and the afterburner are adapted to use gas and liquid fuels. During gas turbine fuel transfer, the gas and liquid fuel flows are controlled in response to the fuel control signal to compensate power output disturbances that typically result from various nonlinearities of fuel system elements. Afterburner fuel transfer is initiated upon completion of gas turbine transfer. During afterburner transfer, the output signals of a temperature controller that otherwise determine the positions of the afterburner fuel control valves are interrupted, and a burner supervisor generates such signals to transfer afterburner fuel flow at a desired flow rate. Upon completion of transfer the burner supervisor returns control of the fuel valve positions to the controller, which resumes control bumplessly.
