The switchers can isolate the faulted branch , restrict the faulted scale and ensure the supply of non - interruptions such that the reliability of distribution power system is improved . at the same time , the switchers are 配電網(wǎng)開關設備的配置包括開關設備類型、數(shù)量、位置的確定,而其優(yōu)化配置與定位就是從開關設備的備選位置集合中選擇一最優(yōu)方案,使停電收益最大,或開關設備的投入使停電損失的減少最大。
In the next place , an improved algorithm of grounding fault location for tree - type distribution system which is based on new fault function and criterion measure , is proposed in order to complete fault branch ide ntification , fault location and fault value . a lot of the simulation of fault diagnosis and location by computer demonstrate that the algorithm is effective 其次論文基于輻射狀饋線的任一分支線路發(fā)生接地故障,通過分析與推導,建構了配電線路單相短路點定位的故障定位函數(shù)和相應的故障判據(jù),利用樹網(wǎng)單端信息完成故障分支識別、故障定位和過渡電阻定值。
The transient solution obtained from the multi - loop mathematical model are in agreement with experiment results approximately under the conditions that saturation is not severe . though the errors of currents in some non - fault branch seem a little large , the fundamental components of the simulation current are accurate 結果表明,多回路數(shù)學模型在電機飽和不嚴重的情況下,暫態(tài)仿真結果與實驗結果大致吻合,雖然有時非故障分支電流與實驗結果的差異比較大,但基波分量還比較準確,基本可以滿足保護方案的靈敏度校驗等工程需要。
In power system full dynandc simulation software , the adndttance matrixes of fault branches are adopted in the fault models to simulate arbitrary symmetrical and unsymmetrical faults , by use of contraction technique for adndttance matrix the multi - faults and the randomly occurred faults can be processed . the feature of this method is that the arbitrary multi - fault occurred in a branch can be simulated without any additional branches or buses to be added , thereby , the ca1culation efficiency and the expedience of usage are improved 本文提出采用故障支路導納陣處理復故障計算,該算法可以對一條支路發(fā)生任意重故障進行處理,而不需要增加支路或節(jié)點,克服了目前常用的電力系統(tǒng)機電暫態(tài)程序在處理復故障時,一般要按照事先預想的故障類型以及故障和操作發(fā)生的位置增加新的節(jié)點和小開關支路的問題。
