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.

The present application provides a process for preventing rotating stall and surge in a turbomachine compressor. The compressor may include air extraction pipes connecting the compressor to a turbomachine exhaust area or to the atmosphere, at least one of the pipes is fitted with a flow regulation valve, and each valve has an adjustable degree of opening. The process includes, for at least one of the valves, a complete opening command when the compressor rotation speed is less than a predetermined threshold value beyond which there is no longer any risk of rotating stall and surge and a command for lowering the degree of opening of the valve when the rotation speed of the compressor exceeds the threshold value.
