摘要
知识图谱技术作为一种能够描述客观世界中概念、实体间复杂关系的新方法,以强大的知识推理能力被广泛关注。调度控制中心是电网运行控制的中心枢纽,为了推动智能调控建设,结合知识图谱技术以及调控领域的具体情况,提出了面向智能调控领域的知识图谱构建方法。进而针对实际调度的需求,提出了用于支撑运行规则电子化、故障处置、倒闸操作、对话问答等应用场景的知识图谱应用方案。最后,构建了线路故障处置知识图谱,通过应用表明,所建立的知识图谱能够自动驱动线路故障处置流程,流程判定识别准确率较高,有效地降低了人工处置风险。
Knowledge graph technology is a new method describing the complex relationship between concepts and entities in the objective world,which has been widely concerned because of its strong knowledge inference ability.Dispatching and control center is the central hub of power grid operation control.In order to promote the construction of intelligent dispatching and control,combined with the technology of knowledge graph and the specific situation in the field of dispatching and control,this paper proposes the construction method of knowledge graph oriented to the field of intelligent dispatching and control.Furthermore,the application solutions of knowledge graph for supporting the scenario of fault handling,operational rule electronization,breaker operation and dialogue question and answer are put forward.Finally,the knowledge graph of line fault handling is constructed,showing that the established knowledge graph can drive the process of line fault handling automatically,and the accuracy of judgment and identification process is higher,which effectively reduces the risk of manual handling.
