Problems solved by technology

[0003] At present, in the distribution network management system that has been implemented in my country, most of the electrical wiring diagrams are manually drawn by CAD drawing software, which not only has a large workload, but also has hidden dangers of inconsistent data and graphic configurations.
With the development of social production, the demand for electric energy is increasing day by day, prompting the transformation of the power grid and the frequent changes of the lines, which greatly increases the workload of the maintenance personnel of the electrical wiring diagram of the power distribution network

Embodiment Construction

[0026] Embodiments include, a graphical object-oriented distribution network single-line diagram vector drawing tool, and further include,

[0027] 1), point-arc model data structure;

[0028] 2), the topology algorithm of breadth-first traversal;

[0029] 3), layout of electrical graphic elements based on maze algorithm;

[0030] 4), the elimination of overlapping and crossing of primitives or lines.

[0031] The devices in the geographical wiring diagram of the distribution network are divided into point types and arc types, and the geographical wiring diagram of the distribution network is expressed as a topological relationship network between points and arcs through the connection of points and arcs.

[0032] The breadth-first traversal method is used to construct the topological relationship between distribution network equipment of different scales.

[0033] While constructing the topological relationship, obtain the device path with the most devices connected to the...

Abstract

The invention relates to an automatic switching system from a geographical wiring diagram of a distribution network to a single line diagram; the system comprises a vector drawing tool of a single line diagram of a distribution network, which faces to a graphic object; the system also comprises a point arc model data structure, a breadth-first ergodic topology algorithm, an electrical primitive layout based on labyrinth algorithm, and elimination of primitive or line overlapping and intersection. A distribution network model based on CIM is proposed on the basis of geographic information of the distribution network by combining the vector drawing tool of the single line diagram of the distribution network, and automatic switching from the geographical wiring diagram of the distribution network to the single line diagram is realized according to the geographical wiring diagram of a distribution network to a single line diagram among geographical wiring diagram equipment by the labyrinth algorithm and the method of eliminating overlapping and intersection method, thereby greatly reducing the working load of maintenance personnel of the single line diagram, eliminating the hidden trouble of inconsistence of data and diagram and improving the working efficiency of distribution departments and reliability of a power system in the practical application.

Description

technical field [0001] The invention relates to a drawing software, in particular to an automatic conversion system for distribution network geographic wiring diagrams to single-line diagrams. Background technique [0002] The electrical wiring diagram is a schematic representation of the state of the power grid. Most of the dispatching functions are realized by it, and it is an indispensable graphic data in the operation and management of the power system. [0003] At present, in the distribution network management system that has been implemented in my country, most of the electrical wiring diagrams are manually drawn by CAD drawing software, which not only requires a large amount of drawing work, but also has hidden dangers of inconsistent data and graphic configurations. With the development of social production, the demand for electric energy is increasing day by day, prompting the transformation of the power grid and the frequent changes of the lines, which greatly inc...
