Abstract

The invention relates to a method for generating a local topology of an intelligent power distribution terminal, including the generation of a topology of an adjacent intelligent power distribution terminal and the generation of a local topology, specifically including the following steps: obtaining a description of the topology of the entire network of a distribution network; reading the local topology that needs to be generated According to the distribution network topology description of the target intelligent power distribution terminal, obtain the local switch attribute of the target intelligent power distribution terminal; read the local switch of the target intelligent power distribution terminal, and use the depth-first search algorithm to perform topology analysis and generate The adjacent intelligent power distribution terminal attribute of the target intelligent power distribution terminal generates the topology of the adjacent intelligent power distribution terminal; judges whether the local switch of the target intelligent power distribution terminal is greater than 1, and if so, scans each local switch, based on the power distribution Network-wide topology description and generate local topology. Compared with the prior art, the invention can conveniently realize the precise conversion from the whole network topology of the distribution network to the local topology in the intelligent power distribution terminal.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to a method for generating local topology of smart power distribution terminals. Background technique [0002] The distribution network has a large scale and complex wiring, and the access of distributed power sources increases the difficulty of distribution network automation control, and the technical requirements for distribution automation are getting higher and higher. Due to the wide range of terminal equipment points in the distribution network, the construction and maintenance costs of distribution automation are very high. At the same time, the effective access of a large number of distribution automation equipment and the reduction of maintenance workload are major problems faced by the application of distribution automation technology for a long time. . With the advancement of technology, various intelligent power distribution terminals are more and more applied to the distrib...
