Power grid SVG (Scalable Vector Graphics) graphic file, creation method and creation system thereof

Abstract

The invention relates to a power grid SVG graphic file, a creation method and a creation system thereof. The creation method comprising the following steps of: analyzing a first moment power grid SVG graphic file and storing the power grid SVG graphic file in a first buffering zone according to the type organization form of SVG graphs; copying the content stored in the first buffering zone to a second buffering zone; analyzing a second moment power grid SVG graphic file and storing the power grid SVG graphic file in a third buffering zone according to the type organization form of the SVG graphs; comparing differences of the contents stored in the first buffering zone and the third buffering zone according to the type organization form of the power grid SVG graphs, and increasing SVG graphic objects, deleting the objects and modifying the attributes of the objects in the second buffering zone according to the compare results, wherein the power grid SVG graphs in the second buffering zone creates expanded time attributes; and creating a graphic file for describing the modification state of the power grid graphs in a period of time according to the type organization form of the SVG graphs including the expanded time attributes in the second buffering zone.

Description

technical field [0001] The invention relates to a scalable vector graphics (Scapable Vector Graphics, SVG) file for a power grid, a method for generating the graphic file, and a system for generating the graphic. Background technique [0002] SVG is a unified and open standard recommended and released by W3C. The main purpose of the introduction of SVG graphics is to realize the graphics exchange between different systems, different manufacturers and different power companies. In the power dispatching center, the SVG format has become the most common graphical interactive format for system diagrams (geographical and schematic) and primary wiring diagrams between different EMS / SCADA systems and between EMS / SCADA systems and other systems. [0003] SVG graphics are applied to the grid mainly through the SVG graphics <g>graphics group, in <g>A whole graphics entity and device object is defined in the graphics group, and a consistent corresponding relationship is e...

AI Technical Summary

Problems solved by technology

[0004] However, since the SVG graphics used in the current power system only describe the graphics of the plant or system at a certain moment, it cannot describe the changes in the SVG graphics of the power grid within a certain period of time

This has two disadvantages: on the one hand, it will lead to too frequent exchange of SVG graphic files between different systems, that is, every time the SVG graphic changes, it needs to exchange SVG graphic; on the other hand, only the latest SVG graphic is kept inside the EMS system , without recording the changes of the grid SVG graphics over a period of time

Even if SVG graphics with changes are used for storage, for SVG graphics with multiple minor changes (such as system diagrams, GIS diagrams, etc.), the storage space is relatively large
