双馈风力发电机绕组匝间短路故障诊断综述

Summarization on Fault Diagnosis of Turn-to-turn Short Circuit in DFIG

在风电市场上双馈风力发电机(DFIG)凭借其卓越的性能,被广泛投入使用。综述了双馈风力发电机常见的一些故障类型,以及定、转子发生匝间短路的故障机理。同时针对这两种故障展开分析研究,并提出了一系列相应的故障诊断方法。最后对其绕组故障诊断的发展趋势做了简单阐述。

In the wind power market,doubly fed wind turbines （DFIG） are widely used for their excellent performance.This pa per reviews some common faults of the DF1G and the failure mechanism of stator and rotor turns short circuit. At the same time, this paper analyzes the two kinds of faults and puts presents a series of fault diagnosis methods.Finally,describes the de velopment trend of winding fault diagnosis briefly .
