Research on the principle of distribution network fault handling

Abstract

Compared with the transmission network, the distribution network has a wide distribution area, a large number of electrical equipments, a complex operating environment and a high probability of fault. According to the operation characteristics and common fault types of distribution network, this paper first describes the main task and basic mentality of distribution network fault handling, and then puts forward the handling principles of distribution line fault, single phase-to-ground fault and voltage transformer fault, which provides technical support for dispatchers to deal with distribution network fault reasonably.
