摘要：

Under the background of the continuous improvement of gas turbine manufacturing localization, some gas turbine components deviate from the original design value, but the control parameters are not adjusted accordingly, which leads to the phenomenon of continuous vibration of gas turbine fuel valve in the process of speed-up. Basing on algorithm of typical start-up processing of 9E-DLN (Dry Low NOx) gas turbine, FSR (Fuel Stroke Reference) calculation criterion is studied according to the control method of GE Company. Through the establishment of gas fuel valve transfer function control model, the response of fuel system will be changed as control parameters vary. Finally, simulation results are provided to optimize the control parameters and provide some suggestions for the optimization of the control parameters.
