ABSTRACT:
A controller is disclosed that operates a gas turbine such that a desired reserve power capacity is maintained. The inlet guide vane angle of the compressor is applied as an indicator of the reserve capacity of the gas turbine. The actual inlet guide vane angle is continuously compared to an intended inlet guide vane angle that corresponds to a desired reserve capacity. A controller adjusts the fuel flow to the gas turbine to adjust the turbine output power and thereby maintain the actual inlet guide vane angle at the intended value corresponding to the desired reserve capacity.
