Abstract

The invention discloses an intelligent substation protection logic action visualization method based on a G graphic technology. The method is characterized by mainly comprising the following six functional modules: a protection logic diagram layer and primitive construction module, a protection fault logical reasoning module, a protection fault node information base module, a protection fault information acquisition module, a fault diagnosis positioning module and a protection action loop visualization module. According to the invention, the protection logic layer and the primitives can be constructed according to the protection classification and protection implementation information in the SCD file based on the electric power G graphic specification; and a protection fault logic rule base and a protection fault node information base are constructed by utilizing the protection classification information and the protection realization related information, and visual display of protection logic actions of the intelligent substation is achieved by combining a G graphic protection logic diagram layer and primitives based on protection fault logic rules so as to quickly diagnose powergrid faults.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to a method for visualizing logical actions of intelligent substation protection based on G graphics technology. Background technique [0002] At present, the State Grid is rapidly promoting the construction of smart substations. However, in smart substations, cables between traditional substation equipment have been replaced by optical fibers, traditional secondary circuits have been replaced by communication networks, and optical digital signals have replaced traditional electrical signals. Realized the networking of secondary equipment. This change makes the connection between devices no longer intuitive, and the one-to-one connection between a large number of virtual terminals is summarized in the same optical fiber. Simple and intuitive electrical signals no longer exist, and there are a large number of complex data messages in the communication network. , so t...
