联合动力1.5 MW风电机组变桨失效原因分析及应对措施

Analysis of Causes of Pitch Failure of United Power 1.5 MW Wind Turbine and Countermeasures

文章通过对历次联合动力1.5 MW风机变桨失效案列进行原因分析和对比,找出变桨系统设计存在的安全薄弱点,然后制定技改思路,从源头上杜绝变桨失效飞车的安全隐患。总结历次应急处置成功的经验,制定现场应急处置措施,丰富现场应急处置的手段和应对措施,极大提升变桨失效处置的成功率,有效避免飞车倒塔事故发生。

This article analyzes and compares the reasons for the failure cases of pitching of 1.5 MW wind turbines of previous joint powers,finds out the weaknesses of the design of the pitch system,and then formulates the technical reform ideas to eliminate the hidden safety hazards of the pitching failure from the source.Summarizing the experience and lessons of successful emergency response,formulating on-site emergency response measures,enriching the on-site emergency response measures and response measures,greatly improving the success rate of pitch failure treatment,and effectively avoiding the accident of flying tower collapse.
