配电网自适应智能型快速故障定位与就近隔离技术研究

Research on Adaptive Intelligent Fast Fault Location and Nearby Isolation Technology for Distribution Network

提出一种基于配电网分级保护的自适应智能型快速故障定位与就近隔离技术方案,主要阐述该方案的线路保护配置、馈线自动化策略、保护逻辑原理以及故障隔离与供电恢复过程等内容。所提方案无须依赖通信和配电自动化主站系统,便能够实现故障的快速定位与就近隔离。

In this paper,an adaptive intelligent fast fault location and nearby isolation technology scheme based on distribution network classification protection is proposed.This paper mainly expounds the line protection configuration,feeder automation strategy,protection logic principle,fault isolation and power supply recovery process of this scheme.The scheme proposed in this paper can quickly locate and isolate faults without relying on the communication and distribution automation master station system.
