Gas turbine control system and method for single-shaft combined cycle plant
An object is to maintain a constant gas turbine output without requiring a complicated procedure on site and without being affected by variations in the output of a steam turbine during a reverse-washing/normal-washing switching period of a condenser. A gas turbine control system for a single-shaft combined cycle plant generates a gas turbine output command using a parameter reflecting a gas turbine output during a reverse-washing/normal-washing switching period of a condenser and generates the gas turbine output command on the basis of a generator output command and a steam turbine output during a period other than the reverse-washing/normal-washing switching period of the condenser.
