Security control strategy knowledge graph construction method and system for AC-DC power grid

The invention discloses a safety control strategy knowledge graph construction method and system for an AC-DC power grid, and belongs to the field of power grid dispatching. The method comprises the following steps: establishing a safety control strategy ontology model; obtaining structured data and unstructured data of the AC/DC power grid; performing knowledge extraction on the structured data and the unstructured data to obtain security control strategy entities, attributes and relationships; and writing an input script based on the constructed security control strategy ontology model, and storing security control strategy entities, attributes and relationships in a graph database to complete construction of the security control strategy knowledge graph. The method assists regulation and control personnel in fault disposal decision making, and provides powerful technical support for new-generation engineering construction. 本发明公开了一种面向交直流电网的安控策略知识图谱构建方法及系统，属于电网调度领域，方法包括：建立安控策略本体模型；获取交直流电网的结构化数据和非结构化数据；对结构化数据
