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.

[ What is claimed is:] [1.] A method for regulating the fuel flow to a combustor of a gas turbine having a computer control system with a droop governor and transient load controller, wherein the method comprises the following steps:a. capturing with the transient load controller a current power output value of the gas turbine at the beginning of a transition phase of the gas turbine;b. applying the current power output value to generate a temporary power output set point in the transient load controller;c. calculating in the transient load controller a difference signal indicative of the difference between the current power output value of the gas turbine and the temporary power output set point;d. generating a compensation signal in the transient load controller indicative of the difference signal calculated in step (c), ande. applying the compensation signal in combination with a signal generated by the droop governor to adjust the fuel flow to the combustor.
