Historical inversion method and system for secondary circuit of intelligent substation

Abstract

The invention discloses a historical inversion method and system for a secondary circuit of an intelligent substation. The method comprises: collecting and storing state information related to the secondary circuit; querying and arranging to obtain effective historical state information related to the secondary circuit; initializing a historical secondary circuit visualization diagram, and displaying historical secondary circuit remote signaling state change information in a list; and inverting and displaying a historical secondary circuit. According to the invention, the historical state datarelated to the secondary circuit of the intelligent substation is stored and inquired, and the historical state and change of the secondary circuit are inverted in the form of graphs and lists, so that the visual historical tracing of the secondary circuit is realized. The historical state of the secondary circuit of the intelligent substation can be rapidly mastered and the historical fault of the secondary circuit can be accurately positioned so that the visualization and fault positioning functions of the secondary circuit of the intelligent substation can be perfected, the technical meansof intelligent operation and maintenance of the secondary equipment of the intelligent substation can be expanded and safe and stable operation of the intelligent substation can be further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of intelligent operation and maintenance of secondary equipment of an intelligent substation, and relates to a historical inversion method and system for a secondary circuit of an intelligent substation. Background technique [0002] The secondary circuit of the smart substation mainly relies on optical fiber and network. The entire secondary system is based on the SCD file, and the traditional terminals have been replaced by "virtual terminals". Therefore, compared with the secondary circuit connected by conventional conventional substation cables, the secondary circuit of the smart substation becomes an invisible "black box". In order to change this situation, the secondary circuit visualization technology and secondary circuit fault diagnosis technology of smart substations continue to develop and mature. [0003] At present, the secondary circuit visualization technology of smart substation is mainly di...

AI Technical Summary

Problems solved by technology

Although the information and diagnostic reports that occurred when the secondary circuit failed will be saved for later query and analysis, these information are only a large amount of discrete text information, which cannot be reversed and displayed on the secondary circuit visualization diagram, which is not intuitive enough and is not conducive to history Secondary circuit fault analysis and location
