Based on the common information model(CIM)of IEC 61968
the information and topology connection of distribution network equipment are analyzed. The four-parameter method is used to map the geographic information system(GIS)coordinates of the equipment to the grid-based drawings to complete the initial layout. A multi-objective optimization model is proposed for the optimization goal of “uniform distribution of towers
uniform distribution of stations
less intersecting lines and uniform distribution of the whole elements”. And the layout is optimized using the Cauchy variant particle swarm optimization algorithm with linearly decreasing strategy. Finally
automation generation of single line diagram for distribution network is realized
which achieves a balance between flexible and beautiful. Scalable vector graphics(SVG)files can be generated to share with mobile devices and meet the needs of operating and maintaining for distribution network.
