AI Technical Summary

Technical Problem

Existing wind turbine generators are prone to ice buildup in environments with low temperatures, high humidity, frequent rain, snow, and hail, which reduces wind energy capture efficiency, increases the load on rotating parts, and causes mechanical damage, thus limiting their widespread use in cold regions.

Method used

The wind turbine adopts a protective design, including an adaptive support, a vibration de-icing device, and a shielding protection device. The vibration de-icing device releases the blades from their fixed position and performs high-frequency vibration de-icing, while the shielding protection device protects the blades from hail impacts, ensuring stable operation of the unit.

Benefits of technology

It effectively solves the problem of ice buildup on wind turbines in low-temperature environments, improves the stability and power generation efficiency of the unit, prevents mechanical damage, and expands the application of wind turbine generators in harsh low-temperature environments.
