摘要
简要介绍配电网的典型供电结构及馈线保护现状,分析、比较配电网中馈线保护的4种模式:传统的电流保护、基于重合器的馈线保护、基于FTU的馈线保护、基于快速通信的馈线系统保护,提出保护功能独立、基于快速通信的配电网馈线系统保护模式是一种最优控制模式。
This paper introduces the typical power supply structure of distribution network and feeder protection briefly, analyzes and compares four kinds of feeder protected modes of distribution network： traditional electric current protection, feeder protection based on re closcr, feeder pro tection based on FTU and feeder system protection based on quick communication. Finally, this paper points out that feeder system protection mode based on quick communication whose protective function is independent is the optimal control mode.
