Abstract:
1. A method for controlling a specified power reserve of a gas turbine power plant having an input means which generates a load set-point signal for the gas turbine power plant and a controller which receives the load set-point signal and regulates a power output of the gas turbine power plant, the method comprising: arranging a processor coupled to a memory to: continuously update an estimate of the maximum power generation capacity of the gas turbine power plant; calculate a load offset by specifying a power reserve and determining the load offset from the specified power reserve; calculate a load limit as a difference of the estimate of the maximum power generation capacity and the load offset; and apply the load limit as an upper limit of the load set-point signal to obtain a limited load set-point signal.
