摘要
文献曾对非线性电路故障诊断问题进行了研究,并给出了一些方法,本文则针对这一问题主要阐述几个观点:即在确定非线性电路的故障时,(1)求支路电流增量和电压增量;(2)求非线性支路电压增量;(3)分两部进行——先诊断故障线性支路(或节点)再诊断故障非线性支路(或节点),文中还对有关方程的求解问题进行了讨论,并给出了算例。
This paper proposes three view-points on the fault diagnosis:(1)to lay stress on determining branch current increments and branch voltage increments,(2)to be based on getting nonlinear branch voltage increments, (3)to divide the fault diagnosis process into two,at first,to diagnose faulty linear branches(or nodes),then to locate faulty nosmlinear branches(or nodes).The results shows that each opinion given in the article is an effective approach to finish the fault dragnosis of nonlinear circuits. The problem of solving relevant equations is discussed, and is pointed out the fact that the methods presented can be used to both function description and curve description of characteristics of nonlinear components.
