有源网络拓扑分析与网络的故障诊断

本文研究有源网络的故障诊断问题，着重研究其可解性与可诊断性，在分析两种形式的有源网络典型支路和基础上，把无源网络的网孔方程、节点方程、回路方程、割集方程推广为有源网络下的相应方程，并提出了一组基于节点分析的故障诊断方程，最后，提出了关于网络理论第三类问题的扼要观点。

A Topological Analysis of Active Network and Network Fault Diagnosis

The fault diagnosis problem of active network is studied in this paper with the emphasis upon its solvability and diagnosability. Based on the analysis of two typical branch forms of the active network, the mesh equation, node equation, loop equation, and cut set equation of passive network are generalized to suit the active network case. A set of fault diagnosis equation for node analysis is presented. Finally, an important idea about the third class problem of network theory is presented briefly.
