容差子网络级故障诊断

FAULT DIAGNOSIS OF TOLERANCE SUBNETWORK

该文在故障子网络等效电流矢量的基础上,讨论了子网络的测试特性,得到了容差条件下故障子网络判断的必要条件。该方法在诊断过程中可对各子网络同时做出诊断,不但能加快诊断过程,而且可消除误差传递性的问题,对于容差故障诊断具有理论和实际意义。

In this paper,the test property of fault subnetworks has been discussed based on the fault subnetwork equivalent current vector, and the essential condition for determinting fault subnetworks has been given. Using this method, every subnetwork may be diagnosed at the same time independently. The method not only may quicken diagnosis process, but also may solve the error transfer question. Thus, this paper should have theoretical and practical significance for tolerance fault diagnosis.
