Abstract

PURPOSE: To enable the operation of a gas turbine in the maximum efficiency by obtaining the combustion temperature from air flow rate obtained by atmospheric temperature and pressure and regulating the inflowed air flow rate so that the combustion temperature remains constant.
CONSTITUTION: In a gas turbine in which air regulated in flow rate by an inlet guide vane is compressed by a compressor and is fed to a combustor, the atmospheric pressure signal Ps is first multiplied by a multiplier 12 by the output of a signal generator 11 when the vane is controlled. This multiplied value is then multiplied by a multiplier 14 by a signal produced from a function generator 13 in response to the atmospheric temperature signal Ts, and the air flow rate is obtained by an adder 15 based on the output. This air flow rate is passed through a correcting function generator 17, and is multiplied by a multiplier 18 by an exhaust gas tmperature signal Tx, and the valve opening to become the maximum combustion temperature at that time is obtained. Then, the signal and the guide vane opening signal M are reduced by a subtractor 22, and the guide vane opening is regulated via a proportional integrator 19 according to the output.
