自适应重合闸型馈线自动化的应用实践

Application Practice of An Adaptive Reclosing Feeder Automation

文章介绍了一种基于断路器的自适应重合闸型馈线自动化方案及实际应用情况。该方案适用于变电站投入重合闸、且至少能实现一级级差配合要求的配网线路,通过断路器“失压分闸、来电延时合闸”、后加速跳闸动作逻辑,可实现在变电站开关跳闸1次的情况下隔离故障区域并恢复供电。

This paper introduces a circuit breaker-based adaptive reclosing feeder automation scheme and its practical application.This scheme is suitable for substations that are reclosed and can at least achieve the requirements of first-level differential coordination.Through the circuit breaker’s“lost voltage opening,incoming call delayed closing”and the later accelerated tripping action logic,it can be switched on and off in the substation.In the case of a trip,isolate the fault area and restore power.
