Abstract: In one embodiment, a power generation planning support apparatus includes an acquiring module configured to acquire a physical quantity that represents a startup condition of a turbine. The apparatus further includes a first storage module configured to store first information that represents a relationship between a startup schedule of the turbine and the physical quantity. The apparatus further includes a predicting module configured to predict the startup schedule of the turbine, based on the physical quantity acquired by the acquiring module and the first information stored in the first storage module. The apparatus further includes an outputting module configured to output the startup schedule predicted by the predicting module.

Abstract: 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.
