Automatic power distribution network single line diagram drawing method based on improved gravitation repulsion model

Abstract

The invention relates to an automatic power distribution network single line diagram drawing method based on an improved gravitation repulsion model and belongs to the technical field of electric power system dispatching automation. According to the method, firstly, all devices and connection relations which belong to one feeder line are read from a power grid public information model; all the read devices are abstracted into nodes, the connection relations between the devices are abstracted into lines, and a foundation network structure chart is completed; then, the device nodes are replaced with 8-node rectangular frames, and layout adjustment is performed on the structure chart by using the improved gravitation repulsion model; a final layout is generated through orthogonalization, intersection removal and connecting line contraction; finally, information including node positions, device types, device names and electrical attributes of the devices in the final layout are output to a single line diagram file, device diagrams replace the 8-node rectangular frames, and drawing of a power distribution network single line diagram is completed. The single line diagram drawn with the method has attractive and compact layout and lines do not intersect and overlap.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a method for automatically drawing a single-line diagram of a distribution network without overlapping intersections based on an improved attraction-repulsion model. Background technique [0002] The one-line diagram is the basic graphic data used in the power system, which records the logical connection and additional information of various equipment in the power grid, and is widely used in daily work such as power grid system planning, control, operation, and management. Traditional manual one-line diagrams contain information such as equipment, connection lines, and text descriptions. For example, figure 1 It is a partial image of a one-line diagram in a certain area. The dotted lines and solid lines in the figure represent the lines in the power grid, and the special graphics connected to the lines represent the equipment in th...

Problems solved by technology

The one-line diagram of the distribution network generated by the gravitational repulsion algorithm directly, because the size of the equipment graph and the canvas is not considered, there will be overlaps and intersections between lines and equipment, and the one-line diagram will have poor results. It is difficult to ensure that the final generated diagram is compact and beautiful. It is difficult to ensure that the lines and equipment in the figure do not cross or overlap at all
