| 摘 要： | 提出一种基于支持向量机(SVM)的可控整流电路故障诊断方法。只需要通过对整流阀输出波形的直接分析,利用SVM进行模式识别,就可对整流装置进行故障诊断。以三相桥式晶闸管(SCR)整流电路为例,进行了验证。通过实验研究结果表明:该方法能准确地对可控整流电路进行故障诊断和故障定位,具有良好的实用价值和广阔的应用前景。

| Abstract: | Based on support vector machines (SVM) theory, a new method of fault diagnosis for controlled rectifier circuits is proposed in this paper. Fault diagnose method of power electronic converter has been studied on the basis of direct waveform analysis and SVM. Three-phase bridge rectifier circuit fault is presented as an example, coupled with the results of a certain power electronic circuit experiment, indicates that the method can accurately diagnose and locate fault for controlled rectifier circuits, which is justified practical and applicable for controlled rectifier circuit fault diagnosis. |
