ABSTRACT:
Method and apparatus for controlling fuel flow in a combustion turbine, wherein a speed reference signal is given and wherein an actual speed signal is given, is shown to include a fuel flow regulator for regulating the flow of fuel in response to a control signal, a controller for generating a control signal representative of the difference between the actual speed signal and the speed reference signal, a first adjustment member for modifying the speed reference signal to account for droop prior to generation of the control signal, and a second adjustment means for modifying the speed reference signal to account for speed error also prior to generating the control signal. A load condition specifically envisioned for use with the present invention is the point of closure of the generator breaker.
