Problems solved by technology

At present, the commonly used optimization algorithm is based on the graphs that have been drawn, and local adjustments are made to avoid crossing between graphs as much as possible. However, this optimization algorithm is only applicable to the drawing of single-line diagrams of distribution networks.

Abstract

The invention discloses a layout optimization method of distribution network thematic maps. The method includes the steps of optimizing the distribution network thematic maps of different types by means of force-directed layout, and performing optimization in a topological tree layout manner according to the need for local layout optimization. By the use of the method, the problems such as graphic overlapping, unreasonable layout and connecting line crossing occurring in manual drawing or using of the distribution network thematic maps are solved. At the premise of accurate and complete graphic representation, graphic layout is uniform, moderate in size and attractive and clear, and the availability and readability of the distribution network thematic maps is partly improved.

Description

technical field [0001] The invention relates to a distribution network thematic map layout optimization method, which belongs to the technical field of distribution automation. Background technique [0002] In distribution automation technology, thematic map is a specific grid connection diagram formed for the needs of distribution network business, including single-line diagram, ring network diagram, etc. At present, there are two main sources of thematic maps for distribution automation master station system: manual drawing and grid GIS platform. Among them, the manual drawing is drawn by the professionals of the power system on the special graphics editing software. During the drawing process, due to the large number of picture frames, the connection relationship is complex, and the manual drawing is time-consuming, error-prone and has poor synchronization. With the increasing scale of the distribution network, the number of devices and the complexity of the lines conti...
