Intelligent substation primary-secondary equipment state information visual displaying method based on configuration files and G language

Abstract

The invention relates to the technical operating field of intelligent substation operation and maintenance, and especially relates to an intelligent substation primary-secondary equipment state information visual displaying method based on configuration files and the G language. The visual displaying method is suitable for intelligent substations adopting the IEC 61850 standard. According to the invention, a main wiring diagram and a spaced wiring diagram of primary equipment are automatically generated in dependence on the configuration files of the intelligent substation, by associating an intelligent terminal, a merging unit and a protection device with each other, the primary equipment and secondary equipment of the intelligent substation are organically connected and visually displayed, the application field of the configuration files is expanded, the topological relation between the primary equipment and the secondary equipment and state information of the primary equipment and the secondary equipment are visually displayed in a graphical manner, operation and maintenance of the equipment are convenient, and the safety control level of the intelligent substation is improved.

Description

Technical field [0001] The present invention relates to the technical operation field of operation and maintenance of smart substations, in particular to a visual display method of primary and secondary equipment status information of smart substations based on configuration files and G language. The method is suitable for smart substations adopting the IEC61850 standard. Background technique [0002] Smart substation is a substation based on a unified standard and unified communication model. The primary equipment and topological relationships, secondary equipment and loop connections of the substation are described and configured by SCL language, and exist in the format of an extensible markup language XML file to form a standardized configuration file for the substation. SSD and substation configuration file SCD. At present, the application of configuration files is mainly the substation configuration file SCD of secondary equipment and circuit connection. The configuration fi...

Problems solved by technology

[0004] For the substation normative description file SSD, it has not been effectively applied at present. Some studies use scalable vector graphics SVG to realize the construction of the main wiring diagram of the primary system based on SSD. When editing the main wiring diagram of a system, it is easy to repeat the equipment coordinates and overlap the graphics, which affects the generation of the main wiring diagram of the primary system; in addition, no further application has been carried out based on the generated main wiring diagram. The main reason is that the primary system and the The secondary equipment is treated separately, and the primary system and secondary equipment are not combined. The main wiring diagram of the primary system has no correlation with the description of the secondary equipment and the circuit connection. The primary and secondary equipment in the smart substation is gradually integrated and the technology is constantly improving. Under the current situation, a new method is needed to organically connect and visualize the primary and secondary equipment in substations, expand the application field of configuration files, and graphically and intuitively display the topology relationship and status information between primary and secondary equipment, so as to facilitate equipment operation and maintenance, and improve Safety control level of smart substation
