Abstract:
A method for open-loop control operation of a fuel supply system that supplies a fluid fuel to a burner arrangement with one or more burners for a gas turbine,in which the fuel supply system has on the inlet side a control valve that feeds the fuel into the fuel supply system as a function of its actuation, in which, firstly, as a function of a requested burner output, a first setpoint is determined for a fuel mass flow with which the burner arrangement must be supplied in order to be able to furnish the required burner output, in which as a function of this first setpoint of the fuel mass flow a second setpoint is determined for the fuel mass flow, which is then fed into the fuel supply system by an appropriate actuation of the control valve, and in which the second setpoint of the fuel mass flow is selected such that the fuel supply system fed therewith supplies the burner arrangement essentially with the first setpoint of the fuel mass flow.
