摘要:

在构建以新能源为主体的新型电力系统背景下,知识图谱(KG)作为可视化的大型语义网络在电力运检中的应用处于快速发展阶段。近年来,KG在电力运检的应用主要集中在语义信息方面,然而电网运行中会产生大量异构数据,足以支撑构建多模态知识图谱(MMKG),为多种下游任务提供数据支持。从电力运检的功能需求出发提出引入MMKG解决综合智能问答系统和故障处置问题,重点介绍了针对电力运检数据的MMKG构建技术,总结了MMKG能够发挥作用的电力运检功能场景,并对未来发展方向做出展望,最后深入分析了发展MMKG会面临的挑战,为电力运检智能化发展与建设提供参考。

Abstract:

In the context of building a new power system with new energy as the main body,knowledge graph(KG),a large-scale visual semantic network,is expanding its applications rapidly in power operation and inspection. The applications of KG in power operation and inspection mainly focus on semantic information processing. However,a large amount of heterogeneous data will be generated in power grid operation,being able to uphold the construction of multimodal knowledge graph(MMKG) which provides data support for various downstream tasks. In view of functional requirements on electric power inspection, MMKG is introduced to support the intelligent query answering system and fault handling. Expounding the construction technology of MMKG for power inspection data,the scenarios of power operation and inspection that MMKG can give full play in are summarized,and the development direction is forecasted. Finally,the challenges that will be faced by MMKG is analyzed comprehensively,which provides a reference for the development of intelligent power operation and inspection.

Key words: new power system, knowledge graph, multimodality, power operation and inspection, fault handling, artificial intelligence, big data
