In order to improve the efficiency of operation, maintenance and overhaul of secondary equipment in substations, this article mainly focuses on the application research of self-learning technology in the generation of secondary installation measures in substations. Firstly, study the operation state switching of the secondary system, establish the operation switching strategy control of the secondary system, and propose the overall design process of the operation switching of the secondary system; The fuzzy relationship matrix of fuzzy mathematics uses self-learning fuzzy inference theory to generate intelligent security tickets for expert reasoning and interpretation; finally, complete the semantic matching of security measures and manual confirmation of security tickets. After system debugging, the time for generating security tickets and visual display for each IED device in the smart substation is no more than 10 seconds, which effectively improves the management level and efficiency of safety measures for equipment in smart substations.
