[0059] Simplify distribution network topology

[0060] 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.

[0061] The method to simplify the distribution network topology is as follows:

[0062] 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.

[0063] ②For any two switchgears that are directly con...

Abstract

The invention discloses a method for automatically generating a single-line diagram of a distribution network based on topology layering, which comprises the following steps: deleting some related equipment in the topology structure of the distribution network, simplifying the topology structure of the distribution network; obtaining the distribution network The key nodes of the topological structure generate the backbone skeleton of the topological structure of the distribution network; the position of the key nodes is laid out based on the attraction-repulsion model to obtain a skeleton structure based on the attraction-repulsion force; The data structure of the node-branch line model is used to describe the topology of the distribution network; the layout and automatic drawing of the equipment in the power station are completed on the basis of the topological structure of the equipment in the power station; Overlap cross-wiring graphs. The invention realizes the automatic generation of the one-line diagram of the distribution network above a certain scale, and at the same time, makes the generated one-line diagram clearer and more beautiful by avoiding overlapping and crossing wiring algorithms.

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. Background technique [0002] 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. [0003] 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 transmission n...
