摘要
针对超高压输电线路是否需要采用分布参数特性来分析继电保护的动作行为进行讨论,推导了横分量法和对称分量法模型.结合500kV双端网络,进行了线路故障稳态计算,并仿真4种保护的动作判据,详细讨论了两种算法对保护的动作行为的差别,得出具有实际意义的结论.
For analyzing the effect of distributed parameters of ultra-high voltage transmission line on relay performance, the mathematical models of symmetrical component methodand modal analysis method are derived in this paper. Then the criteria of relay are simulited.Using these two methods, this paper realizes the stable calculation of short-circuit fault anddiscusses in detail the performance differences of relay combining with 500kV two-terminalnetwork. By numerical analysis, some acceptable conclusions are proposed.
