Research and Systematic Implementation of Interactive Configuration Method Based on SSD Primitive Extension Model

The topological relationship of the conducting equipment and the information on the size and location of the primitive are defined in the Intelligent Substation System's Specification Description Document (SSD), but the layout rules for drawing the graphics of various types of conducting equipment are not clear, the information on the drawing of each conducting equipment is not comprehensive, and the SSD based on the SCL language are unreadable

. Therefore, it is difficult to visually verify the accuracy and integrity of configuration information, which makes it harder for construction and debugging. In this paper, standard primitives of various types of conducting equipment in SVG format are constructed, and the method of finding out the topological relationship of conductive equipment in the bay is studied by using the connection information between the devices in SSD. The layout rules of substation drawing, such as incoming line bay string, outgoing line bay string and bus, are given to construct the primitive extension model on the basis of completing the primitives' information of conducting equipment in SSD. In this paper, an interactive configuration scheme of intelligent substation's primitive extension model is proposed, which integrates the interactive configuration system based on SSD primitive extension model, and achieves the interactive configuration of all substation's graphic information and the automatic drawing of equipment's single-line diagram. Ultimately, in this paper, the feasibility of the scheme and the effectiveness of the system are verified through a practical example of an intelligent substation, which improves the intelligent substation's efficiency and accuracy in the construction and debugging.
