Abstract
A cooling device includes a hot-part cooling system configured to guide air to a hot part of a gas turbine. The hot-part cooling system includes a compressor capable of operating independently of the gas turbine, and is configured to extract air inside a casing of the gas turbine to pressurize the air with the compressor and guide the air to the hot part of the gas turbine. The cooling device further includes a rotor cooling system configured to extract the air inside the casing of the gas turbine and guide the air to a turbine rotor, and a connecting system configured to guide the air pressurized by the compressor to the rotor cooling system while a fuel supply to the gas turbine is stopped.
