PROBLEM TO BE SOLVED: To prevent the corrosion of a blade and to miximize an increase in electric power. SOLUTION: By water injection control systems 42, 52, and 62 for water supersaturation systems 26, 54, 66, 68, and 82 arranged in a gas turbine intake system 60, an electric power output of a gas turbine 10 operated in a high peripheral air temperature condition is increased while a water content, which is represented by a measured gas turbine operation parameter, in air in an intake port is maintained within limits allowable for the gas turbine. The control systems control the star and stop, regulation, and restriction of water injection fed to the supersaturation systems on the basis of a gas turbine parameter showing operations of the humidity or dew-point temperature of circumambient air, the dry-bulb temperature of the circumambient air, a gas flow in a compressor inlet, with a maximum output or an output close to it.
