A Visualized Automatic Drawing Method of Distribution Network

Abstract

A visual distribution network automatic drawing method, including the following steps: S1, read the CIM model file, convert the CIM model file analysis into a hierarchical structure, generate the original topology map of the distribution network, and use the original topology map of the distribution network as a graph The database is stored as a carrier; S2. Find out the topological relationship between equipment and branches according to the original topology diagram of the distribution network, and generate a feeder diagram; S3. Find out the connection relationship between feeders according to the feeder diagram of all distribution stations in the Unicom area. Generate distribution network interconnection graph; S4, extract graph data of distribution network original topology graph, feeder graph and distribution network interconnection graph, establish connection between nodes according to graph data, and render graph appearance. The method can automatically update and generate the power grid topology map according to the change of the power grid topology data; realize the automatic visualization display of the power grid topology map, facilitate the real-time monitoring and analysis of the power grid situation, and save the human resources and time required for traditional drawing.

Description

technical field [0001] The invention belongs to the technical field of automation, and in particular relates to a visualized automatic drawing method for a distribution network. Background technique [0002] Distribution network visualization is the basic support for power grid operation monitoring and manual analysis. At present, distribution network drawing mainly adopts manual and human-computer interaction drawing methods. For example, the Chinese patent application with application number 201210271369.7 "A method and System", which completes the construction of the power grid topology map according to the user's operation of electronic equipment. However, in the literature "Gao Yan et al., "CIM-based Graphical Grid Topology Modeling and Analysis", "Journal of Hefei University of Technology", Vol.33 No.5, May 2010, it is pointed out that a manual drawing of equipment graphics elements and A method for automatically establishing connections based on layout. [0003] How...

Problems solved by technology

However, the real topology of the distribution network will continue to change with the optimization and debugging of the network in actual operation, and the manual drawing method cannot achieve the graphical change based on real-time data.
