Based on a state of the gas turbine, either a normal start mode or a hot start mode is selected as a start mode. When startup control is started based on the start mode, the rotational speed of the gas turbine gradually increases. In a low rotational speed region, an opening degree of the inlet guide vane provided by a compressor is maintained at a first opening degree and a bleed valve is maintained at second opening degree. In a high rotational speed region, the inlet guide vane is controlled at first intermediate opening degree greater than the first opening degree and the bleed valve is controlled at a second intermediate opening degree less than the second opening degree. The first intermediate opening degree is set to be larger in the hot start mode. The second intermediate opening degree is set to be larger in the hot start mode.
