The dynamic performance simulation analysis effect of three-axis gas turbine is improved,and the dynamic performance simulation method of three-axis gas turbine for large ship power generation is proposed.The dynamic character-istics of three-axis gas turbine for power generation of large ships are calculated.Using Simulink as the development tool,the dynamic performance simulation model of three-axis gas turbine which can run in the computer is obtained,and its dynamic performance is simulated and analyzed.Through steady-state analysis,the data errors obtained by this method under differ-ent working conditions are small,all of which are controlled within 5％,which shows that the dynamic performance simula-tion model of three-axis gas turbine constructed by this method is accurate.Under the condition of continuous sudden load discharge,the flow rate of high and low pressure compressor and the speed of high and low pressure rotor of three-axis gas turbine show a gradient downward trend.When the load is suddenly unloaded,the fuel flow decreases rapidly,and when the load is stable,the fuel flow increases slightly after being processed by the fuel controller.
