摘　　要：风力发电机飞车事故是风电场运营过程中的防控重点。围绕海南东方市某风电场一起飞车事故,分析了飞车事故的原因,结合飞车防范要素,分别提出了无条件自控应急顺桨的机组防飞车方法,对风机控制的颈部神经中枢滑环滑道及取电设置和配套软件进行了优化,并应用于风电场的全场风机中,取得良好的效果,可供类似风电场同行借鉴。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.
