Research on Feeder Automation System for Urban Distribution Network

Abstract

Abstract With the development of society, the demand for power supply reliability is also increasing, and the proportion of terminals with feeder automation function in the distribution network is increasing. It has become a research hotspot to find more optimized feeder automation strategy. This paper introduces three kinds of feeder automation schemes: centralized control type, local control type and distributed control type and expounds the fault isolation, non-fault section power supply self-healing strategy in detail. The comparison of several control schemes provides reference for choosing feeder automation scheme according to system architecture.
