GAS TURBINE CONTROLLER

摘要

Occurrence of combustion vibration is prevented in a gas turbine plant by enhancing the degree of freedom in setting an air flow rate or a fuel flow rate in correspondence with a target load thereby enhancing combustion stability. A gas turbine controller comprises a first function generator (62) for setting the flow rate of fuel or air being supplied to a combustor (32) in correspondence with a target load, an intake temperature detector (22) for detecting intake temperature at the inlet of a compressor, a second function generator (69) for setting a correction amount of a set value of fuel flow rate or air flow rate based on the value detected by the intake temperature detector (22), a third function generator (66) for setting a modification amount of the correction amount while taking account of the target load, a first operating unit (68) for operating a modified correction amount from a correction amount set by the second function generator and a modification amount set by the third function generator, and a second operating unit (64) for calculating the flow rate of fuel or air being supplied to a combustor by adding the modified correction amount to the set value of fuel flow rate or air flow rate set by the first function generator.
