A METHOD OF SINGLE BRANCH-FAULT IDENTIFICATION THROUGH NULLOR SUBSTITUTION ON TREE TYPE POWER NETWORK
-
摘要: 本文提出一種樹型電力網(wǎng)單一故障分支的識別方法零泛器替代法。這種方法的特點(diǎn)是診斷所需要的端口變量易于測量,對于短路和斷線故障都適用,測后計(jì)算量較少。適用于多分支的樹型電力網(wǎng)單一故障分支的識別。經(jīng)計(jì)算機(jī)模擬,證明了所提識別方法是有效的。

Abstract: A new method is presented based on nullor substitution, which is suitablefor detecting single faulty branch with short-circuit or open-circuit on tree type power network. The required current and voltage values of each port are easy to be measured, and the proposed method needs less computations after measurement. It is feasible for single faulty-branch location on tree type powed network with several branches. Simulation by computer shows satisfactory results. -
