Embodiment Construction

[0031] The technical problem to be solved by the present invention is: the existing automatic drawing technology can only draw simple one-line diagrams. For the existing increasingly complex distribution network, especially the distribution network connected into a mesh and ring, the existing automatic drawing technology is insufficient. The technical idea proposed by the present invention with respect to this technical problem is: to design a set of encoding algorithm for the node grid coordinates of the one-line diagram, thereby determining the relative orientation between the nodes of the one-line diagram, and then, according to the connection situation between the nodes of the one-line diagram, adjust The position of the one-line diagram node; finally, according to the symbol size of the one-line diagram node, determine the final position of the one-line diagram node, so as to draw the power distribution one-line diagram.

[0032] In order to make the technical purpose, te...

Abstract

The invention discloses an automatic generation method and system for a power distribution single line diagram and an automatic modification method. The automatic generation method comprises the following steps of S1, determining a reference node O of the power distribution single line diagram; calculating and determining grid coordinates of all single line diagram nodes according to the referencenode O of the power distribution single line diagram; then, drawing a connecting line between single line diagram nodes to obtain an initial power distribution single line diagram; S2, performing graph optimization on the initial distribution single line diagram according to the objective function F to obtain a secondary distribution single line diagram; and S3, replacing all single-line diagramnodes of the secondary power distribution single-line diagram with corresponding symbols to obtain a final power distribution single-line diagram. The automatic generation method and system of the power distribution single line diagram and the automatic modification method are ingenious in design and high in practicability.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an automatic generation method, system and automatic modification method of a power distribution single-line diagram. Background technique [0002] The power distribution one-line diagram is one of the most important basic data in the power distribution management process. It is an important basis for formulating plans, reporting data, and statistical reports. It is an indispensable and important data for scheduling, operation, maintenance, customer service, and engineering. Traditional methods generally use drawing tools or CAD to draw one-line diagrams. This management method not only has a large workload, but also requires high technical level of technicians. Due to differences in technical level, work experience, and operating habits among different technicians, it is difficult to unify the one-line diagrams drawn by different technicians, and the quality varies, making i...
