Description

Technical Field

[0002] At present, wind power generation technology is developing rapidly, and wind turbines are generally installed in open areas such as mountains, border areas or coastal areas. Due to the remoteness of the area and the often harsh weather conditions, dust and foreign matter often accumulate on the surface of wind turbine blades, or ice easily forms on the surface of the blades in winter. This can easily lead to changes and differences in the weight of the blades, making it difficult to maintain a good balance between the blades, causing the wind turbine to vibrate during rotation, affecting the overall structural stability of the generator set. At the same time, the increase in the weight of the blades increases the load on the connecting components, which affects the service life of the connecting components. In addition, when the surface of the blades is covered with dust and other foreign matter for a long time, the curved surface angle of the blade surface changes, which affects the aerodynamic performance of the blades and the overall power generation efficiency.

[0003] A wind turbine is a device that uses wind energy to generate electricity. During wind power generation, the speed of the wind turbine usually needs to be adjusted through a control system to adapt to different wind speeds and load conditions. However, if the speed of the wind turbine is too fast, it may cause damage to the wind turbine itself.
