Research on fault ranging method of Baoshan 220 kV power grid transmission line

考虑保山220 k V电网行波测距装置实际配置情况,在传统双端行波测距基础上,提出采用故障线路和健全线路上的行波故障信息进行保山220 k V电网线路故障测距的双端行波测距新方法。本方法可实现行波测距在保山电网线路故障定位上的全面应用,仿真验证其测距效果较好。

Considering the actual configuration of the wave distance measuring equipment in Baoshan 220 kV power grid, on the basis of the traditional double-end traveling wave ranging, this paper proposes a new method of double-end traveling wave ranging based on the fault information of fault lines and non-fault line. This method can realize the comprehensive application of traveling wave ranging in Baoshan 220 kV power grid transmission line. Simulation results show that the distance measurement is better.
