介绍了风机维修现状，研究了风机变桨系统故障数据，通过探索电气滑环更换和变桨通信故障之间的联系，建立了两者的威布尔模型故障函数；分析结果表明：在一年运行时间内，电气滑环随时间的增长更换率更高，而变桨通信则相反，由此可以进一步制定其维修策略。
介紹瞭風機維脩現狀，研究瞭風機變槳繫統故障數據，通過探索電氣滑環更換和變槳通信故障之間的聯繫，建立瞭兩者的威佈爾模型故障函數；分析結果錶明：在一年運行時間內，電氣滑環隨時間的增長更換率更高，而變槳通信則相反，由此可以進一步製定其維脩策略。

Introduction was made to the present situation of wind turbine maintenance and study was made on the fault data of wind turbine variable propeller system. By researching on the relationship between electric slip ring replacement and variable propeller communication system fault, this paper established their Weibull model fault function. The analysis result shows that during one year operation time, the electrical slip ring replacing rate is increasing while the variable propeller communication failure is opposite, which makes the maintenance strategy set down further.
