|
摘要
随着智能变电站在煤炭系统中的试验推广,其所具有的网络化数据共享特征,给解决越级跳闸问题提供了新方法。在确定煤矿智能变电站结构、系统对时、GOOSE通信技术原理及防越级跳闸流程的基础上,重点研究用于故障线路识别的故障区段识别矩阵算法,实现了故障区段的定位与隔离,对提高煤矿供电系统的稳定性有重要意义。
With the promotion of intelligent substation test in coal mine system,the characteristic of network data sharing provides a new approach to solve the over-grade trip problem.Based on the understanding of the structure of intelligent substation,the synchronization technology,GOOSE communication technology and the process of implementation anti-grade tripping,this paper focuses on fault segment identification matrix algorithm for fault line identification,aiming at realizing the identification and isolation of fault segment.This matrix algorithm could determine the fault segment effectively,so as to improve the stability of coal mine power system.
