电力电子线路的故障诊断──利用CAI实现二级基函数字典法

FAULTS DIAGNOSIS OF POWER ELECTRONIC CIRCUIT──REALIZED TOW-GRADE-BASIS-FUNCTION DICTIONARY METHOD WITH CAI

对于电力电子线路的故障诊断，采用计算机辅助分析（ＣＡＩ）的方法获得了二级基函数故障字典，提高了故障定位率（与参考文献２比较），并采用ＴｕｒｂｏＣ完成了电力电子线路故障诊断软件系统的故障定位部分。该法具有实时诊断的功能，使ＳＣＲ电路在线故障诊断的实现成为可能。

About power electronic circuit faults diagnosis,a CAI method is adoped, The tow -grade-basis-function fault dictionary is obtained fault fixed position ratio is raised (Compare with reference papers 2). The fault fixed position part of power electronic circuit fault diagnosis software system is performed with Turbo C. The method can diagnose fault realtime, and this makes it possible to realize on-line fault diagnosis of SCR circuit.
