Abstract:
A gas turbine cooling system (50) is provided with a cooling air line (51) for guiding compressed air compressed in an air compressor (10) to high-temperature components, a cooler (63) for cooling the compressed air in the cooling air line (51), a return line (56) for returning the cooling air in the cooling air line (51) to the upstream side in the cooling air line (51), a return valve (58) for adjusting the flow rate of the cooling air flowing through the return line (56), and a control device (100) for controlling the opening degree of the return valve (58). The control device (100) has a second valve command generator (131) for generating, as a second valve command, a valve command that the opening degree of the return valve (58) be forcibly increased to a predetermined shutoff opening degree when a receiving unit (101) receives a load shutoff command (LC).
