Title:
METHOD FOR CONTROLLING GAS TURBINE COOLING SYSTEM, CONTROL DEVICE FOR EXECUTING THIS METHOD, AND GAS TURBINE FACILITY EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2014/050163
Kind Code:
A1
Abstract:
This gas turbine cooling system (30) is equipped with: a cooler (31) that produces cooling air by cooling compressed air extracted from an air compressor (11); a cooling air compressor (34) that supplies the cooling air to a combustion tube (13) of a combustor (12); and an IGV (35) that regulates the flow volume of the cooling air. This gas turbine cooling system control device (50) is equipped with: a target value setting unit (52) that, in accordance with the detected cooling air temperature, sets a target value for the equivalent flow volume of the cooling air; a corrective drive amount calculation unit (53, 54) that sets a corrective drive amount so as to reduce the deviation in the value for the equivalent flow volume of the cooling air with respect to this target value; and a drive command output unit (57) that outputs to the IGV a drive command in accordance with this corrective drive amount.
