Problems solved by technology

Manually drawn one-line diagrams still have advantages in terms of user customization and drawing aesthetics, but it is also an indisputable fact that the drawing efficiency is low, the drawing cannot be updated according to the topology data in time, and it is difficult to find drawing errors in time
In addition, the common one-line diagram automatic generation method is prone to node overlap. When the node layout is not considered whether the wiring is convenient, it will often lead to problems such as complex wiring, low wiring efficiency, and serious wiring overlap and crossover; and to solve the problem of node overlap. It leads to new problems such as uneven node spacing and asymmetry, and it is difficult to ensure that the generated one-line diagram is compact and beautiful

Embodiment 1

[0065] The distribution network single-line diagram generation method provided by the embodiment of the present invention is realized based on the branch line model of the trunk line, which can improve the layout efficiency and aesthetics of the single-line diagram. The branch line model of the main line is to assign weights to each node according to its complexity, and use the longest straight line with the weighted path of the power supply in the feeder as the main line according to the tree structure of the one-line diagram; then draw the lower branches connected to the main line in the On both sides of the main line (all main lines and branch lines are drawn horizontally or vertically); then use the lower branch line connected to the current main line as the main line to complete the drawing of a deeper branch line; so alternate the main line and branch line until All branches are drawn. It should be noted that: the nodes described in the embodiment of the present inventio...

Abstract

The invention discloses a power distribution network single-line diagram generation method and device and a storage medium. The method comprises the steps: generating a trunk line and branch lines thereof according to a tree structure of a power distribution network single-line diagram; determining layout directions of all branch lines according to a trunk line layout direction input by a user; determining a trunk line head node coordinate, and finishing trunk line residual node layout in combination with a trunk line layout direction; determining branch line head node coordinates according to the father branch of the branch line, and completing branch line remaining node layout in combination with the branch line layout direction; node overlapping detection is carried out on the arranged nodes, and node overlapping is eliminated in a local stretching mode; performing local contraction on all nodes on the trunk line and the branch lines according to the sequence from the tail node to the head node; and carrying out wiring on each to-be-wired terminal of the arranged node. The power distribution network single-line diagram generation efficiency and accuracy can be remarkably improved, and compactness and attractiveness of the single-line diagram are guaranteed.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a method, device and storage medium for generating a single-line diagram of a distribution network. Background technique [0002] The electrical wiring diagram is a visual representation of the topological state of the power grid and an indispensable graphic data for the operation and management of the power system. The distribution network is a grid composed of many distribution lines, consisting of transformers, power distribution rooms, and intermediate distribution lines from the outlet of the distribution substation to the power supply to users. The distribution network one-line diagram is an electrical wiring diagram that visualizes the distribution network by using the specified graphic symbols and equipment connections. With the rapid development of my country's power grid business, higher requirements are put forward for distribution network management. As ...
