FIELD: power industry.
SUBSTANCE: invention relates to power engineering. The combined cycle power plant control method is implemented for stations which contain, at least, a gas turbine and, at least, steam-power generation system, and the station drives, at least, one electric generator hooked to an electric mains, the gas turbine comprises a compressor, and the steam-power generation system comprises a steam turbine, a heat-recovery boiler and a bypass pipeline. The gas turbine is unloaded to the mode in which the compressor operates at the rated speed, and also the steam turbine is unloaded with matching with unloading of the gas turbine, to the mode in which the total load supplied by the station into mains, in essence is equal to zero, while the gas turbine and steam-power generation system are connected.
EFFECT: invention allows to improve efficiency of variation of load of the combined cycle power plants.
