基于模式分析的对称和非对称三相不接地系统故障测距算法研究

A STUDY ON ALGORITHMS OF FAULT LOCATION FOR (A) SYMMETRICUNGROUNDED 3 PHASE SYSTEM BASED ON MODAL ANALYSIS THEORY

基于模式分析理论，提出了不接地三相的两相短路、单相接地和两相接地故障测距的新算法．计算机仿真和实际电网的模拟故障测距试验表明该算法有效．

Based on distributed parameter circuit theory and modal analysis theory,a number of new algorithms of line to line,single line to ground & double line to ground fault location for (a)symmetric ungrounded 3 phase system are proposed in accordance with the characteristic of the system.Simulation of fault location by computer and tests on the fault model simulation lines show that the algorithms presented in the paper are effective.
