As a main structure of wind power generation, a wind turbine gradually develops towards high power, and the problem of system wind-induced damage under the action of strong typhoon is increasingly prominent. China is located on the west coast of the North Pacific ocean, wind power plants are mostly concentrated in regions with abundant wind energy resources such as the southeast coastal region, the southeast coastal region is influenced by dozens of typhoons every year, so that great personnel and property loss is caused, and wind turbines are damaged due to the action of strong typhoons.

At present, how to improve the wind resistance of a wind turbine structure is one of the problems to be solved urgently. Although the wind resistance of the structure can be enhanced by increasing the wall thickness of the tower, the problems of great increase of investment cost, obvious increase of self weight of the structure, increase of construction difficulty and the like are caused, and a series of potential risks are generated, but the stability of a wind turbine system cannot be fundamentally improved due to uncontrollable tower.
