Simulation of the characteristic of wind turbine based on DC machine

Based on the energy conversion principle of wind turbine, the mathematic model about the operation characteristics of wind turbine is built in the paper. According to the model, the control strategy and simulation method of wind turbine based on DC motor are analyzed in detail. The simulation system of wind turbine characteristics is built using Matlab/Simulink software. By using the closed-loop current control for the DC machine in Matlab/simulink, imitate the two typical operational characteristic for the wind turbine. The imitation results verify the possibility of DC machine can imitate the characteristic of wind turbine. And compare the results with that of wind turbine, its consistent with theoretical data and results can be used in the research of wind power generation technology in laboratory.
