Wind power generation refers to converting kinetic energy of wind into electric energy. Wind energy is a clean and pollution-free renewable energy source, is utilized by people for a long time, mainly pumps water, grinds surfaces and the like through a windmill, and is environment-friendly and huge in wind energy, so that people are increasingly paid attention to all countries in the world due to the fact that modern people mainly utilize wind power to generate electricity.
The existing wind power generation system generally comprises an impeller, a transmission component and a generator set, wherein the impeller is blown by external wind power to rotate, and the generator set is driven by the transmission component to generate power. The rotating shaft of the horizontal shaft wind driven generator impeller is parallel to the airflow direction and the ground, and the wind wheel has the main advantage that the wind wheel can be erected at a place higher than the ground, so that the influence of ground disturbance on the dynamic characteristic of the wind wheel is reduced; the rotating shaft of the vertical axis wind turbine is vertical to the ground or the airflow direction, so that the energy of wind from any direction can be absorbed, the wind direction does not need to be adjusted when being changed, and a tail wing or a rectifying plate does not need to be installed. Specifically, the horizontal axis wind driven generator has huge blade and engine room hub structures, the manufacturing cost of the blade is high, and the generator is horizontal to the ground, and the generator set is placed at the top end of the tower frame, so that the transportation, installation and maintenance costs are high, and the horizontal axis wind driven generator is not environment-friendly; the vertical axis wind turbine can receive wind in multiple directions without a yaw device, can be installed on the ground, is convenient to install, maintain, overhaul and control, and has a complex structure.

However, in reality, wind direction and wind speed are changed all the time, so that wind energy has instability, and how to stabilize the output power of the wind driven generator is an important problem of wind power generation technology. The size of a wind wheel of a modern wind power generation system is larger and heavier, so that when the wind direction changes, the tail wing or the rectifying plate controls the impeller to have slow response to the wind direction, the impeller is difficult to follow the rhythm of the change of the wind direction, and the impeller always forms a certain included angle with the current wind direction in practice, so that the wind power conversion efficiency is lower, the impeller is unstable in stress, the abrasion of the whole equipment is faster, and the service life is shortened; in addition, when the wind speed changes, the output power of the wind driven generator also changes, and the output power is unstable.
