MULTIPLE MODE GAS TURBINE ENGINE GAS FUEL SYSTEM WITH INTEGRATED CONTROL

摘要

A method for operating a gas turbine engine is disclosed. The method includes determining whether the gas turbine engine fuel system is in a steady state mode or a transient mode. The method also includes modifying the gas turbine engine power output by modifying a pressure set point of the fuel system while maintaining a fuel control valve in a steady state when in the steady state mode. The method further includes modifying the gas turbine engine output by modifying the position of the fuel control valve while maintaining the pressure set point of the fuel system constant when in the transient mode.

1. A method for operating a gas turbine engine during general operation, the gas turbine engine having a fuel system, the method comprising:
determining whether the gas turbine engine fuel system is in a steady state mode or a transient mode; modifying the gas turbine engine power output to match a change of load or power demand on the gas turbine engine by modifying a pressure set point of the fuel system while maintaining a fuel control valve in a steady state when in the steady state mode; and configuring the pressure set point of the fuel system to a point higher than a gas turbine engine load requires and modifying the gas turbine engine output to match a change of load or power demand on the gas turbine engine by modifying the position of the fuel control valve while maintaining the pressure set point of the fuel system constant when in the transient mode.
