Abstract:
A control system for a gas turbine includes a controller. The controller includes a processor configured to receive a plurality of signals from sensors disposed in the gas turbine engine system, wherein the gas turbine system engine comprises a compressor section fluidly coupled to a gas turbine section. The processor is additionally configured to derive a vanadium content in a gas turbine engine fuel based on at least one of the plurality of signals. The processor is also configured to determine if a control curve should be adjusted based on the vanadium content in the gas turbine engine fuel, and if it is determined that the control curve should be adjusted, then deriving an adjustment to the control curve based on the vanadium content, and applying the adjustment to the control curve to derive an adjusted control curve.
