In order to better research wind power generation technology in the laboratory, this paper analyzes the characteristics of the wind turbine. Then on the basis of the analysis results, a wind turbine simulation model is built in MATLAB/SIMULINK and a simple torque imitation scheme is proposed. The program imitates the output torque characteristics of wind turbine, by controlling the induction motor torque current to control its output torque. The simulation results verify the feasibility of the wind turbine imitation program. It lays the foundation for the wind energy study.
