Power distribution network uniform connection diagram generating method applicable to situation analysis

Abstract

The invention relates to a power distribution network uniform connection diagram generating method applicable to situation analysis. The power distribution network uniform connection diagram generating method includes acquiring original information containing positions and circuits of transformer substations and loads; traversing nodes connected with each node and computing gravitational resultant force of the node; acquiring repulsive force vector sums according to point-side and side-side circumvention; acquiring resultant force and substituting the acquired resultant force into a motion equation with tractive force so as to shift each node; performing iteration until final displacement of each node is smaller than a fixed value and then stopping shifting the node in current topology; leading out the final position of each node, and writing the final position of each node into SVG (scalable vector graphics) to completely generate power distribution network uniform connection diagrams. The nodes represent the transformer substations and the loads. The power distribution network uniform connection diagram generating method has the advantages that requirements of systems on SVG syntax formats can be met; the diagram generating efficiency is high; diagram render effect have distinct gradations after voltage contour lines of the power distribution network uniform connection diagrams are rendered, and control of operating personnel of power distribution networks on situations of the power distribution networks can be greatly improved.

Description

technical field [0001] The invention belongs to the field of situation awareness and visualization of smart grids, and is applicable to a method for generating a uniform wiring diagram of a distribution network used for situation analysis of a distribution network, and in particular relates to a method for generating a uniform wiring diagram of a distribution network suitable for situation analysis generate method. Background technique [0002] Medium-voltage distribution network (hereinafter referred to as distribution network) is one of the power grids that directly determine the quality and reliability of power supply for users. Substation 10kV outgoing line measurement has already existed in substation monitoring; with the full coverage of public transformer terminals and special transformer terminals, the steady-state electrical measurement at the end of the medium-voltage distribution network is also complete; The remote collection of ring network cabinets and cable b...

Problems solved by technology

The geographical wiring diagram of distribution network is a visual graph that reflects the real distribution of distribution network load based on geographical information or reference background. However, geographical wiring diagrams based on real geographic coordinates often have dense loads and crossing lines.
