[0063] Simplify distribution network topology

[0064] Generally, the initial distribution network topology data comes from the production management system, which describes each device in the distribution network and the connection relationship between them in a detailed and comprehensive manner. However, as far as the data required to generate the one-line diagram is concerned, only the main topological data can be taken, so the initial distribution network topological data needs to be simplified before drawing.

[0065] The method to simplify the distribution network topology is as follows:

[0066] ① For any two wire devices directly connected in series, the characteristic values ​​such as impedance and length of one wire device are incorporated into the other wire device, and the previous wire device is deleted at the same time, without changing the original topology connection relationship during the whole process.

[0067] ②For any two switchgears that are directly con...

Abstract

The invention discloses an automatic generation method used for a single line diagram of a distribution network and based on topological hierarchy. The method comprises the following steps: deleting related equipment in a topological structure of the distribution network, and simplifying the topological structure of the distribution network; acquiring key nodes of the topological structure of the distribution network, and generating a main framework of the topological structure of the distribution network; arranging the positions of the key nodes based on a gravitation-repulsion model, and obtaining a skeletal structure based on the gravitation-repulsion; describing the topological structure of the distribution network through an outgoing line-trunk line-T-shaped key node-branch line model of a power station; finishing the arrangement and the automatic mapping of the equipment in the power station on the basis of the topological structure of the equipment in the power station; and performing routing mapping without overlap or intersection on decibels of the trunk line and the branch line respectively. The automatic generation method achieves automatic generation of the single line diagram of the distribution network above a certain scale, and simultaneously, the generated single line diagram is clearer and more attractive through the routing algorithm without overlap or intersection.

Description

technical field [0001] The invention relates to a drawing method of a distribution network, in particular to a method for automatically generating a single-line diagram of a distribution network based on topological layering. [0002] Background technique [0003] The electrical wiring diagram is a visual representation of the topological state of the power grid, and is an indispensable graphic material in the operation and management of the power system. The traditional power grid single-line diagram is manually drawn by CAD drawing software, which not only requires a lot of drawing workload, but also has hidden dangers of inconsistency between topological data and drawn graphics. [0004] At present, the automatic generation system of power grid one-line diagram mainly includes three aspects: automatic generation of electrical wiring diagram of single plant, automatic generation of single-line diagram of single feeder and automatic generation of power flow diagram of tran...
