Style-Based Substation Graph Generation Method

Abstract

The invention discloses a substation graph generation method based on a style. The substation graph generation method is suitable for automatic generation of a monitoring picture of an intelligent substation and is used for solving the problems that a conventional substation monitoring system is low in picture drawing efficiency and the picture is non-standard. The substation graph generation method comprises the steps of automatically generating a guide according to a picture, inputting a precondition, selecting a layout style and a container style, and automatically generating a substation monitoring system picture according to a rule of an arrangement layout. According to the substation graph generation method based on the style, the graph style and the layout style which meet the state code are designed, so that a style library is formed; all monitoring pictures of the substation are easily generated; a complicated monitoring picture can be generated by several steps of operation only according to the guide by inputting the relevant preconditions. The design of the style and the construction of the graph are separated, so that the stability, the maintainability and the expansibility of software are improved. According to the method for generating the graph, the drawing time of engineer is greatly shortened, and the working efficiency is improved.

Description

technical field

[0001] The invention belongs to the field of electric power system intelligent substation automation, and relates to a style-based substation graphic generation method. Background technique

[0002] With the development and improvement of smart grid technology, smart substations have gradually become the key to smart grid technology. The substation monitoring system is the core part of the smart substation, and the monitoring system is presented to the operators first by a graphical interface. The graphical interface should have a reasonable layout, clear layers, clear labels, clear meanings, concise and beautiful, and fully meet the actual needs of power grid operation and regulation business. . A typical substation monitoring system includes monitoring screens: index diagram, photon card diagram, main wiring diagram, interval sub-diagram, application function sub-diagram, secondary equipment status monitoring diagram, monitoring system network communicatio...

Examples

Embodiment Construction

[0024] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0025] At present, the substation voltage level of my country's power grid is as follows: figure 1 As shown, the backbone network is mainly 110KV and 220KV, and a few UHV transmission lines will be above 500kV. If the voltage level, the number of main transformers, and the number of lines of a substation are known, then the general structure of the substation can be determined. In the process of automatic graph construction, we call these conditions preconditions. In addition, we introduce the concept of style, which refers to the definition of the format of power graphic elements and the definition of the layout of graphic elements that conform to the national grid graphics standard, and the atlas composed of various styles is called a style library. The preconditions are input through the generation wizard, and the style library is designed...
