Abstract

The invention discloses a fault handling method of distribution automation equipment in a distribution system. The method comprises: a communication network is constructed by using all distribution network management equipment in a distribution network as nodes; an upstream and downstream relation of all distribution network management equipment in the distribution network is determined; a fault report is generated; according to the fault report, a substitute distribution network structure with fault equipment and / or line shielded is constructed; combination ways of on-off states of all loops and / or distribution automatic terminals during construction of the substitute distribution network structure in the distribution automation system are calculated and a corresponding control instruction is generated; and according to the control instruction, the on / off state of the corresponding distribution automatic terminal is controlled. Therefore, the real-time and automatic maintenance operation for a fault can be realized without manual intervention by the maintenance staff, so that the maintenance performance of the distribution network can be improved substantially.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a fault handling method for distribution automation equipment in a power distribution system. Background technique [0002] Distribution automation system is an automation system that enables distribution enterprises to monitor, coordinate and operate distribution equipment in a remote manner in real time; [0003] The distribution network automation system generally consists of the following parts: distribution master station, distribution substation, distribution network management equipment and communication network; [0004] Distribution network management equipment generally includes feeder terminal unit (Feeder Terminal Unit, FTU), distribution automation terminal (Distribution Terminal Unit, DTU) and distribution transformer monitoring terminal (distributionTransformer supervisory Terminal Unit, TTU) and other equipment. [0005] Taking the feeder terminal equipment as an ex...
