プラントの起動制御装置。 In a combined plant consisting of a gas turbine, an exhaust heat recovery boiler that recovers exhaust gas from the gas turbine and generates steam with different pressures of high and low pressures, and a steam turbine that is driven by the high-pressure steam and low-pressure steam, the steam turbine control valve is used. The opening change rate is set according to the gas turbine load change rate or a function thereof, so that fluctuations in steam pressure can be suppressed, and discharge of surplus steam by the turbine bypass valve can be suppressed as much as possible. Startup control device for combined plants.
