Estimating the term…
A gas turbine provided with: an air cooler that subjects compressed air extracted from a compressor to heat exchange and supplies the cooled compressed air to a cooling system of a rotor system in a turbine; an air cooler bypass line that bypasses the compressed air introduced into the air cooler; an electric valve provided in the air cooler bypass line; and a control unit that controls opening and closing of the electric valve such that, during activation of a gas turbine, a degree of opening of the electric valve is set at or below a low-level degree of opening and such that, after the load of the gas turbine has been increased, the degree of opening of the electric valve is set to be larger than the low-level degree of opening.
A gas turbine comprising:
An activation method of a gas turbine including a compressor configured to compress air, a combustor configured to mix and combust fuel and compressed air compressed by the compressor, a turbine configured to obtain rotational power from combustion gas generated by the combustor, an air cooler configured to subject compressed air extracted from the compressor to heat exchange and supply the cooled compressed air to a cooling system of a rotor system in the turbine, an air cooler bypass line configured to bypass compressed air introduced into the air cooler, and a first valve provided in the air cooler bypass line, the activation method comprising:
