摘要： A controlling apparatus to control a combined cycle power-generating plant, the combined cycle power-generating plant including: a gas turbine; an heat recovery steam generator; and a steam turbine includes a controller that controls an output of the gas turbine. The controller controls the output of the gas turbine at a second output value that is greater than a first output value, after a paralleling of a power generator of the gas turbine, the first output value being a gas turbine output when an exhaust gas temperature of the gas turbine falls within a temperature range that is determined based on a metal temperature of the steam turbine. The controller controls the output of the gas turbine at the first output value, in a case where a temperature of the steam generated by the heat recovery steam generator exceeds a temperature based on the metal temperature.

摘要： A combined cycle power plant feedwater system includes: a feed pump which supplies feedwater to a heat recovery steam generator; a first pipe which extracts part of the feedwater from a flow path in mid-course of pressurization of the feed pump; a first boiler supplied with the feedwater led into the first pipe and subjected to first water treatment; a second pipe where the feedwater discharged from a feed pump outlet flows; a second boiler supplied with the feedwater led into the second pipe and subjected to second water treatment more downstream than the flow path in mid-course of the pressurization; and a water-treating substance supply device which supplies a water-treating substance for the second water treatment to the feedwater flow path in the feed pump, at a position more downstream than a connection position of the first pipe and more upstream than a connection position of the second pipe.
