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 配电网开关设备的配置包括开关设备类型、数量、位置的确定,而其优化配置与定位就是从开关设备的备选位置集合中选择一最优方案,使停电收益最大,或开关设备的投入使停电损失的减少最大。
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 其次论文基于辐射状馈线的任一分支线路发生接地故障,通过分析与推导,建构了配电线路单相短路点定位的故障定位函数和相应的故障判据,利用树网单端信息完成故障分支识别、故障定位和过渡电阻定值。
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 结果表明,多回路数学模型在电机饱和不严重的情况下,暂态仿真结果与实验结果大致吻合,虽然有时非故障分支电流与实验结果的差异比较大,但基波分量还比较准确,基本可以满足保护方案的灵敏度校验等工程需要。
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导纳阵处理复故障计算,该算法可以对一条支路发生任意重故障进行处理,而不需要增加支路或节点,克服了目前常用的电力系统机电暂态程序在处理复故障时,一般要按照事先预想的故障类型以及故障和操作发生的位置增加新的节点和小开关支路的问题。
