摘要
介绍了国内外站域保护的故障定位原理,同时提出一种基于网络拓扑的电流差动站域保护原理,并通过仿真来验证此原理在简化现有保护配置的同时还能提高变电站保护的可靠性。
This paper introduces some fault location principle at home and broad and puts forward a current differential protection principle with station domain based on network topology. We also simulate the principle with PSCAD / EMTDC to make sure that the principle will simplify the existing protection configuration and improve the reliability of the protection of substation.
