The Automatic Generation Algorithm for Single Line Diagrams of Distribution Networks Based on the Layout Model of Branch and Main Lines

To enhance the automatic generation capability of SLD (single line diagram) for distribution networks, an automatic generation algorithm for SLD of distribution networks based on the layout model of branch and main lines was proposed. The automatic wiring control of the distribution network's SLD was performed by incorporating the individual differential characteristic quantities of distribution equipment. During load conditions, the topology structure of the distribution network's single line networking was designed, and the attribute correlation characteristic quantities output by branch and main line nodes in the distribution network's SLD were extracted. This process utilized a connectivity index distribution model between distribution equipment and the distribution network to optimize the positioning design of wiring nodes. Under the layout model of branch and main lines, the automatic fusion control of single line diagrams of distribution networks was carried out. Based on the network structure and operation situation, the automatic configuration and positioning design of distribution network's SLD were carried out and the automatic positioning model of distribution network's SLD was analyzed. By combining fuzzy detection and optimization control methods, the key characteristic selection method of distribution networks was adopted to optimize the deployment design of nodes in the automatic generation process of branch and main lines of distribution network's SLD, achieving the automatic generation of distribution network's SLD. The simulation results showed that using this method for automatic generation of single line diagrams of distribution networks had good optimization ability and strong node optimization deployment ability, and improved the efficiency of distribution network design.
