Optimization method for single line diagram of distribution network system

Abstract

The invention belongs to the technical field of distribution network system single line diagrams, and particularly relates to a distribution network system single line diagram optimization method, which comprises the steps of rearrangement optimization: obtaining primitive information and topological information of a single line diagram, judging the density degree of primitives, and rearranging the primitives of which the density degree exceeds an upper limit; and text optimization: obtaining the primitives of the single line diagram and the texts of the primitives, scanning the position information of other primitives within a certain range around the current primitive, judging the storage positions of the texts of the current primitive according to the position information of other primitives, and storing the texts. According to the method, the actual single line diagram of the distribution network is used as a carrier, the drawing can be beautified quickly, the real-time performance, accuracy and attractiveness of drawing beautification are improved, the field operation and maintenance intensity is reduced, and a good foundation is laid for construction of a distribution automation system.

Description

technical field [0001] The invention belongs to the technical field of single-line diagrams of distribution network systems, and in particular relates to an optimization method of single-line diagrams of distribution network systems. Background technique [0002] At present, the State Grid mainly uses the PMS system to maintain the lines and equipment, and uses the GIS positioning of the equipment and the account information of the equipment to generate a single-line diagram of the line, which is finally pushed to the distribution automation system. However, since the one-line diagram generated based on the GIS diagram and account information only associates the equipment information in the line, the aesthetics of the graphics is not considered enough, and the one-line diagram can only be beautified manually, which is time-consuming and laborious, and it is used in the distribution automation system. The one-line diagram converted by the mapping tool also does not consider t...

Problems solved by technology

However, since the one-line diagram generated based on the GIS diagram and account information only associates the equipment information in the line, the aesthetics of the graphics is not considered enough, and the one-line diagram can only be beautified manually, which is time-consuming and laborious, and it is used in the distribution automation system. The one-line diagram converted by the mapping tool also does not consider the beautification of the graphics, which leads to confusion in the one-line diagram displayed in the distribution automation system. In addition, during the actual operation process, the distribution network line changes relatively large, and it is often necessary to modify the line diagram. The drawings are updated, which increases the workload of drawing maintenance again, which brings serious inconvenience to on-site operation and maintenance.
