This paper studied the working principle, parameter setting and control strategy, the direct-drive permanent magnet synchronous wind power grid system, and built a direct-drive permanent magnet synchronous wind power grid system model in the MATLAB/Simulink simulation software. At the same time detailed simulation analysis was made respectively for working condition of wind turbines and wind power grid system. The correctness of the model parameter setting and control strategy was validated. It provides a basis for the research of wind power grid system,and achieves maximum power tracking effectively,and improves the quality of the grid voltage.
