基于知识图谱的变电站配置文件智能校核技术研究OACSTPCD

Aiming at the problem that the secondary circuit of intelligent substation is inefficient,prone to errors,and una-ble to meet the current maintenance intensity,this paper studies the intelligent verification technology of substation configu-ration files based on knowledge graph.Firstly,the paper expounds the technical principle of knowledge graph,and de-scribes it from two aspects,including the construction framework and the construction steps.The description files of intelli-gent devices in SCD are segmented based on natural language processing technology and matched with the auxiliary phrase thesaurus and SCD virtual circuit template library to ensure the correctness verification of virtual circuits in the next step.A secondary virtual loop verification model of intelligent substation based on knowledge graph is designed to verify the correct-ness of the virtual circuit.For the expanded substation,a method of knowledge supplement and redundancy auxiliary verifi-cation is proposed.Finally,the feasibility of the proposed secondary virtual loop verification model is proved by an example.
