-
摘要: 本文研究樹型電力網(wǎng)發(fā)生單一短路或斷路故障,且故障點線間具有任意量值的接觸電阻時的故障診斷問題。提出了故障點定位和接觸電阻定值的一種方法零泛器替代法。論述了這種診斷方法的原理,建立了診斷方程,提出了算法。最后給出了具有5個分支的樹型電力網(wǎng)短路和斷路故障診斷的算例。Abstract: The problem of fault diagnosis of a tree-type power network with a short-circuit or an open-circuit and a conrac resistance of arbitrary value between lines is studied. Based on nullor substitution, the method presented here is suitable for fault locating and contact resistance evaluating. Principles of diagnosis are discussed, diagcosis equations are established, and diagnosis algorithms are presented. Finally, examples for diagnosing a five-branches tree-type power network with a shore-circuit or an open-circuit art given.
