Problems solved by technology

[0004] The main wiring diagram is a powerful graphical tool for dispatchers to make analysis and decision-making, but it often needs to be drawn manually by specialized personnel
Doing so also enables the dispatcher to view the status of the power grid in a simple and clear manner, but the workload of data maintenance is heavy, and it is prone to human digital errors

Abstract

The invention discloses a method for automatically generating a plant station diagram through an SCD model file. The method comprises the following steps: S1 analyzing the SCD model file so as to generate the topological structure of the plant station model; S2 reading the topological structure of the plant station model so as to generate the corresponding graphic structure; S3, calculating the frame coordinates of each graphic object in the frame layout and structure according to the graphic structure; S4 generating the frame graphic element according to the layout and the frame coordinates of the frame object; S5 generating the connection relationship within the plant station diagram and a plant station diagram database including the attributes of the equipment graphic elements; and S6 generating the frame object and exporting it. The workload of drawing the plant station diagram and the workload of aligning points in each grade system of the electric power automation system can be reduced so as to be favorable for the cross-platform seamless transmission of the main wiring diagram of the substation.

Description

technical field [0001] The invention relates to the technical field of power system analysis, in particular to a method for automatically generating plant and station diagrams through SCD model files. Background technique [0002] The substation specification model SCD file exists in the form of an extensible markup language (XML) file, which describes the topology including the main wiring diagram of the substation. Through the analysis of the topology, it is possible to analyze the voltage level included in the factory station, the standard interval included in the voltage level, the transformer included in the factory station, and the connection relationship between various devices. Build through the main wiring diagram structure of the graphical software tool. Implements the conversion of model files to graph structures. Thus, the function of automatically generating the main wiring diagram is finally realized. [0003] The automatic generation of the main wiring diag...
