Embodiment

[0048] Example: such as figure 1 Shown is a flow chart of a method for automatically forming a single-line diagram of a distribution network based on a weight tree, and the steps are as follows:

[0049] S1. Preprocess the tree topology model; use the CIM model to describe the topological relationship of the equipment, generate a tree topology model, perform preprocessing on the CIM model of the distribution network, and perform topology analysis starting from the first switch in the model, substation, The ring network cabinet, distribution station, T node, and user load are nodes, and the AC line segment with the feeder as the container and the start or circuit breaker as the side, form a tree data structure through topology analysis, and record the container type, and record the result as a container tree, which will be used many times in the future. Store the corresponding equipment, connection points, and terminal information in the container tree node, except for the T n...

Abstract

The invention discloses an automatic power distribution network single-line diagram forming method based on a weight tree. The method comprises the following steps: S1, preprocessing a tree topology model; S2, calculating the weights of tree nodes; S3, drawing a graph; in the step S2, the step of calculating the weights of the tree nodes comprises the following steps: S21, inputting a tree topology model; S22, traversing the current node; S23, judging whether the current node has a child node or not; if so, carrying out the step S24; if not, after the weight of the current node is assigned, carrying out the step S25; S24, assigning child nodes to the current node; S25, calculating the weight of the current node; S26, judging: judging that the current node is equal to the root node-; if so,turning to the step S27; if not, turning to the step S22; and S27, ending. According to the automatic mapping method designed by the invention, mapping software which is efficient in operation, clearand attractive in hierarchy, free of intersection and the like is automatically generated through the single-feeder model, manual intervention is not needed, graphs can be automatically updated alongwith the change of the model, and model information can be conveniently, quickly, intuitively and visually displayed.

Description

technical field [0001] The invention relates to the technical field of electric power layout diagram generation, in particular to a method for automatically forming a single-line diagram of a distribution network based on a weight tree. Background technique [0002] In the operation and monitoring of intelligent distribution network, the maintenance of graphics and models is not only the basis for realizing intelligent dispatching of distribution network, but also the core of realizing intelligent dispatching of distribution network. With the increasing workload of manually maintaining the one-line diagram of the distribution network and the difficulty of mutual interaction caused by the incompatibility of the graphic formats of various manufacturers, the automatic drawing technology of the distribution network based on the CIM standard replaces the manual drawing of graphics. The task becomes more and more important. [0003] At present, there are mainly three types of aut...
