Description
Technical Field

The wind generating set obtains wind energy through the blades and converts the wind energy into mechanical energy to drive the generator to generate electricity, so that the conversion of the wind energy into electric energy is realized, and therefore, the blades are core components of the wind generating set, and the efficiency of obtaining the wind energy is a key factor for determining the generating capacity of the wind generating set. In different regions, the environments facing the wind generating set are different, for example, higher or lower temperature, higher humidity, larger sand wind and the like can cause different influences on the normal operation of the wind generating set. The lower temperature can cause the blade to freeze in the shutdown or operation process, particularly the front edge part close to the blade tip area is easy to freeze, the starting efficiency of the blade can be affected, and the generating capacity of the wind generating set is further reduced.

According to the invention, after the control system of the wind generating set detects that the blade has ice coating, the whole blade is not required to be heated in a time-consuming and power-consuming way for removing the ice coating of the blade, the resonance frequency of the blade is only required to be rapidly determined through the blade control device, and the blade is controlled to generate resonance with certain intensity, so that the ice coating can be cracked, the deicing speed of the wind generating set is improved, the consumption of electric energy when the wind generating set is deicing is reduced, the utilization rate of the wind generating set is increased, and the wind generating set is more rapid and economical.
However, in the using process, the method still has obvious defects: 1. the device uses a single cam structure to vibrate the fan blade, but the effective vibration area is smaller and can not be transmitted to the whole blade, so that the deicing effect is very limited; 2. in the vibration deicing process, if large ice blocks fly off the blades and then directly fall off, huge potential risks are caused to other parts of the wind turbine and personnel on the use site, and potential safety hazards exist.
