ABSTRACT:
A transient control system for a gas turbine controller that cooperates with a droop speed governor to generate fuel commands regulating fuel flow to combustors of the gas turbine. The transient control system provides compensation for variations in the power output of a gas turbine while the turbine is in transient phase operation. A proportional plus integral controller in the transient control system establishes a power output set point at the initiation of a transfer phase and compares the set point to the current power output of the gas turbine. An output signal indicative of the current power output and its set point generated by the proportional plus integral controller is applied to the droop governor to compensate for variations in the power output of the gas turbine during the transient phase.
