The simulation of wind power system play a important role in yield of analysis of wind power generation system, the quantity of wind power generation , power generation system. This paper establish wind model, the wind turbine rotor model, drive trains model, induction machine model ， the electric power electron parts of wind power generation model, Then using soft of MATLAB, we realize the simulation. It introduces the control technology of wind turbine, mainly including variable blade pitch and variable speed control of wind turbine. Using Matlab simulate these. And lists an example of practical applying.)
