Power distribution area topology identification system and method

Abstract

The invention relates to a power distribution area topology identification system and method. The power distribution area topology identification system is composed of an area transformer, a pluralityof intermediate devices and a plurality of terminal devices on an area power distribution line according to an area household relation in an area, wherein the terminal equipment is provided with a terminal topology injection module, the intermediate device is provided with an inter-topology receiving module and an inter-topology injection module, and the transformer area transformer is provided with a transformation topology receiving module. The system is advantaged in that a set of transformer area topology identification system is constructed, a topology injection module actively sends a current pulse signal with the equipment information of the equipment, a current pulse signal sequentially passes through intermediate equipment on a line according to a network-level vein structure, and the intermediate device sends a current pulse signal with the device information of the intermediate device, and so on, the last-stage transformer in the transformer area receives all topological signals, so automatic identification of the topological structure of the transformer area is realized.

Description

technical field [0001] The invention relates to the field of distribution network management, in particular to a system and method for identifying the topology of a distribution station area. Background technique [0002] At present, with the increasingly stringent requirements of the State Grid Corporation of China for the refined management of low-voltage distribution network panorama perception, how to comprehensively improve the management of low-voltage station areas, and identify the topological relationship between the station area and the meter box, and the branch and the meter box , to realize real-time and accurate reporting of the topology structure, and to realize the full integration of the relationship of "transformer-line-branch-meter box-household meter" has become an important guarantee basis for the realization of the refined management requirements of the panoramic perception of the low-voltage distribution network. Due to technical and management problems...
