In order to analyze the transient influence of wind turbine generator on system,the model of wind turbine generator should be built.Mechanism of the fixed-speed wind turbine generator is complex,it’s difficult to build the detailed model.System identification method regards the studied system as a black box,focuses on fitting the external characteristic of the system,it’s suitable to the complex system. Based on the system identification method,the equivalent model of the fixed-speed wind turbine generator is built in the paper,and its parameters are identified using the particle swarm algorithm,the simulation is performed to validate the equivalent model in the MATLAB.
