摘要
故障在线诊断的关键问题在于只用一次测试结果能定位故障。在子网络转移阻抗和子网络空间概念的基础上 ,分析了测试点电压增量与故障子网络空间的关系 ,提出了将测试点电压增量投影到子网络空间定位故障子网络的方法。该方法仅需一次测试结果 ,且不依赖于子网络内的结构和参数 ,故可用于“黑箱”
The key to fault diagnosis on line is that the fault may be located after only one test have be done.In this paper,the relation between the voltage increment of testing node and the space of fault subnetwork is discussed on the concept of subnetwork transfer impedance and subnetwork space,and the method of locating fault subnetwork is presented.Using this method,only one testing result is enough,rather than depending on structrue and parameter in subnetwork,therefore this method is good for fault diagnosis of black box subnetwork.
