10kV配网自动化系统常用故障定位隔离技术研究

Research on Common Fault Location and Isolation Technology for 10kV Distribution Network Automation System

本文重点围绕配网自动化系统和组成框架进行浅要分析,同时重点对两种故障定位隔离方案——基于馈线终端(FTU)纵联差动的故障定位和基于矩阵运算的故障定位进行比较,对两种常用的故障定位方案的适用情况进行建议。

This paper briefly analyzes the distribution network automation system and its composition framework,and compares two fault location and isolation schemes,namely the fault location based on feeder terminal unit(FTU)longitudinal differential protection and the fault location based on matrix operation,and proposes suggestions on the applicability of the two commonly used fault location schemes.
