Abstract:
1. A combined cycle power generating plant, comprising: a gas turbine power generating section that is provided with a gas turbine; a steam turbine power generating section that is provided with a steam turbine; a boiler that supplies steam to the gas turbine and the steam turbine; a steam supplying section that supplies steam to the gas turbine; a first steam pipe that directs steam from the steam supplying section to the gas turbine; a second steam pipe that directs steam from the gas turbine to the steam turbine; a first release section that carries out control such that the supply destination of the steam that is directed to the first steam pipe is to one of either the gas turbine or an outside of the combined cycle power generating plant; a second release section that carries out control such that the supply destination of the steam that is directed to the second steam pipe is to one of either the steam turbine or an outside of the combined cycle power generating plant; and a bypass pipe that directs at least a portion of the steam inside the first steam pipe to the second steam pipe between the gas turbine and the second release section, wherein the first release section carries out control such that the supply destination of the steam that is directed to the first steam pipe is to the outside of the combined cycle power generating plant when the combined cycle power generating plant starts up, and wherein the second release section carries out control such that the supply destination of the steam that is directed from the first steam pipe to the second steam pipe via the bypass pipe is to the outside of the combined cycle power generating plant when the combined cycle power generating plant starts up.
