摘　　要：针对人工校核智能变电站二次回路效率低、容易出现错误,无法满足当前检修工作强度的问题,文中研究了基于知识图谱的变电站配置文件智能校核技术。文中阐述了知识图谱的技术原理,从知识图谱的构建框架和构建步骤两个方面描述;基于自然语言处理技术切分SCD中智能设备描述文件,并与辅助短语词库和SCD虚回路模板库匹配,为下一步虚回路正确性校验提供保障;设计了基于知识图谱的智能变电站二次虚回路校验模型,验证虚回路的正确性,对于改扩的变电站,提出了知识增补及冗余辅助校核方法。实例分析证明了基于知识图谱的智能变电站二次虚回路校验模型的有效性。Aiming at the problem that the secondary circuit of intelligent substation is inefficient,prone to errors,and unable to meet the current maintenance intensity,this paper studies the intelligent verification technology of substation configuration files based on knowledge graph.Firstly,the paper expounds the technical principle of knowledge graph,and describes it from two aspects,including the construction framework and the construction steps.The description files of intelligent 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 correctness of the virtual circuit.For the expanded substation,a method of knowledge supplement and redundancy auxiliary verification is proposed.Finally,the feasibility of the proposed secondary virtual loop verification model is proved by an example.
