摘要
本文提出一种以故障暂态能量为基础的超高速方向保护的基本原理。本文的方法解决了其它故障暂态量方向保护普遍存在的一些问题。仿真计算表明,该方法可以在故障发生后两毫秒内判定故障方向。
A method of ultra high speed direction relay based on fault transient energy is deseribed in this paper. The method deseribed can solve some problems associated with other direction relay based on fault transient signals. Simulation studies show that the direction to the fault is determined within the first two milliseconds following the inception of a fault.
