The rapid development of wind power technology and the rapid growth of wind power installed capacity reflect the national strategy.

So how to effectively control the vertical axis wind power generation system has become the most critical issue. During the working process, by using the predicted wind speed value to control the angle of attack of the blades of the wind turbine and the angle of attack of the synchronous generator, the control parameters caused by the setting time of the control parameters lag behind the real-time wind speed changes, which will cause voltage fluctuations , frequency fluctuations, wind turbine losses.
