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...
