Embodiment Construction

[0028] The content of the present invention will be described below in conjunction with specific embodiments.

[0029] Based on SVG technology and SVG graphic element theory, the power grid topology graphic element is constructed according to the distribution network model based on CIM (Common Information Model, public information model). The topology definition principle in CIM is: all electrical equipment are designed as multi-terminal components, such as line segments and switches are double-terminal components. All components have endpoints defined to enable topological relationships between electrical components or to form electrical wiring systems. Specifically include the following steps:

[0030] Step 1. According to the different types of distribution network structures contained in the 10KV distribution network model, construct SVG graphic elements with different graphics. The types of substations include ordinary distribution stations, switching stations, etc...

Abstract

The invention relates to an SVG technology-based distribution network modeling system. The single-line diagram of the distribution network modeling system is generated according to the following steps: SVG entities are respectively constructed with different patterns according to different types of distribution network structures contained in a distribution model; according to the branch information contained in a distribution network wiring diagram, the basic branch entities of an SVG topological diagram are constructed; node entities and branch entities are respectively constructed with different colors and solid and dotted patterns according to operating states; the entity shape of each equipment in a distribution network is customized in advance; the data of a power grid model are accessed and read; and the single-line diagram of the distribution network is formed by merging, and a closed loop model is automatically generated. The SVG-based pattern vector display technology disclosed by the invention can efficiently and visually display distribution network wiring diagrams in real time. The SVG technology-based distribution network modeling system can effectively increase working efficiency and provide a variety of appropriate topological diagram display modes for users, and is used in various power grid analysis works.

Description

technical field [0001] The invention relates to a distribution network modeling system, in particular to a distribution network modeling system based on SVG technology and an automatic generation system of the system. Background technique [0002] The distribution network single-line diagram is a powerful graphical tool for dispatchers to make analysis and decision-making, but it often requires specialized personnel to draw it manually. The traditional one-line diagram of distribution network is drawn by AutoCAD design software. Doing so also enables the dispatcher to view the grid status in a simple and clear manner, but the workload of data maintenance is heavy, and it is prone to human digital errors. Therefore, it is necessary to design corresponding topological structures and graphic algorithms based on the existing geographic information structure to realize the automatic generation of single-line diagrams, reduce the workload for electric power personnel, and improve...
