Abstract
Fuel regulating valve is the basic tool to accurately control the fuel flow rate and unit load of gas turbine. Based on the displacement-flow characteristics of the regulating valve and its hydraulic servo mechanism, a mathematical model of the position servo system of the fuel valve was established, and the dynamic response characteristics of the fuel valve group and its control system were analyzed. The influence of inlet pressure on the regulation valve performance was studied, and a fuel inlet pressure correction compensation control method was proposed. The simulation results show that after pressure correction, the system responce bandwidth becomes 0.5 Hz wider, and the amplitude margin increases 20°.
