Direct Driving Permanent Magnet Synchronous Wind Power Systems MPPT Method Research

As a green energy, wind power in the rapid development in our country, the permanent magnet synchronous generator direct driving type of wind power systems, because of its high efficiency, easy fabrication, the control effect good. advantages, have gradually become the research focus. But because the wind speed and wind power system the randomness of the nonlinear, the maximum power point capture is still difficult to control, this paper according to the characteristics of wind turbines, discusses the track, capture the maximum wind power of several MPPT method and the advantages and disadvantages of various methods, and torque control upon in today's two main direct driving type wind power of the application of the topological structure, this paper analyzes the system to the maximum power point tracking the choice of methods and research have certain reference value guidance.
