Abstract

See full text

Method and apparatus for controlling fuel flow in a combustion turbine, wherein a load signal representative of the load on the combustion turbine is given, are shown to include fuel flow device for regulating the flow of fuel in the combustion turbine in response to a control signal, a controller for generating a control signal representative of the difference between the load signal and a limit signal and for providing the control signal to the fuel flow device and a limit signal generator for generating the limit signal so that the limit signal is representative of the sum of the load signal and a maximum instantaneous load value, wherein the limiting means varies the limit signal over time from a first value to the sum.
