Abstract: 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.

Abstract: A method of operating a drive system for a load is disclosed. The drive system may have an electric motor/generator and a gas turbine engine. The engine may have a combustor, and main and pilot flow paths via which fuel is supplied to the combustor. The engine may be operable in low and standard emissions modes. A proportion of the fuel that is supplied to the combustor via the pilot flow path may be greater in the standard emissions mode than in the low emissions mode. The method may include determining an engine power requirement of the load, and whether the engine power requirement of the load is sufficiently large to operate the engine in the low emissions mode. Additionally, the method may include operating the electric motor/generator if the engine power requirement of the load is not sufficiently large to operate the engine in the low emissions mode.
