Abstract: Wind turbine overspeed accidents is the key point of prevention and control in wind farm operation. This article focuses on an overspeed accident that occurred at a wind farm in Dongfang, Hainan, and analyzes the causes of the accident. By incorporating the key elements of overspeed prevention, it proposes a method of unconditional automatic control emergency feathering for wind turbine units to prevent overspeed accidents. Then, the slip-ring slide of the neck nerve center controlled by the wind turbines and the power taking settings and supporting software are optimized, it has been applied to the full-field wind turbine of the wind farm, and has achieved good results, which can be used for reference by similar wind farms.
Key words: wind power generation; wind turbine overspeed accident; variable pitch; safety prevention and control
