摘　　要：随着风电产业迅速发展壮大,风电机组的故障问题受到广泛关注。风电机组中的核心部分为其电控系统,本文针对电控系统故障频发的现象,主要讨论了系统的故障诊断问题。文中介绍了电控系统中的常见故障,主要对影响系统较大的主控PLC故障和变桨故障进行研究。提出将时域分析方法应用于以上的故障诊断中,通过相关参数的比较,检测系统故障。Along with the rapid development of wind power industry,the problem of wind turbine failure has caused much concern. The central part of wind turbines is its electric control system. This article mainly discusses the fault diagnosis of the control system. It introduces the common faults of the electric control system,and analyzes the PLC control system failure which is the major factor for the system fault. Finally it suggests the time domain analysis method to the fault diagnosis. Detection can be done through the comparison of related parameters.
