四相整流电路故障的参考模型诊断算法
资料介绍
四相整流器是一种新型的整流电路,较之传统的三相整流有多方面的技术优势,但目前还没有专门应用于该电路的故障检测、分析系统。针对四相整流电路中常见的晶闸管断路故障。提出了应用参考模型法结合快速傅立叶变换和小波包变换的分析方法,并以此设计了相应的元器件故障诊断系统,在仿真中对其进行了验证。
Compared to the traditional three-phase rectifier, the four-phase rectifier as a new type of rectifier circuit, has various technical advantages. But there are no special fault detection and analysis system used in this circuit. A new analysis algorithm that based on reference model method combined with fast Fourier transform and wavelet packet transform is presented for the common fault of the thyristors" breakers in fourth-phase rectifier circuit. The corresponding component fault diagnosis system is designed and verified in simulation.
