ABSTRACT
Wind power is an involved in electrical, mechanical, computer science, meteorology and other interdisciplinary. With the rapid development of economic society, the growing demand for energy, represented by wind and renewable energy into the line of sight of people. Existing will to power is given priority to with coal power structure type diversity, energy “clean”, “green”. “Control” plays a very important role in modern wind farms. Wind power has a serious instability, in order to maximize reduce wind turbines power grid to the adverse impact of the power grid, reduce wind turbine aerodynamic load and mechanical load, which requires high performance, high reliability of wind power conversion and control device. And that for in order to enhance the service life of wind turbines, raise the efficiency of the wind farm has a positive role.
