摘 要: 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。

Abstract: 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.
        Key words: Weibull distribution; variable propeller system; electric slip ring; fault model
