Abstract

The present invention relates to the technical field of data metering management for power distribution networks, and in particular, to a method for constructing a multi-source heterogeneous data knowledge graph of a power distribution network. The method comprises: model layer construction: summarizing and analyzing a power transmission network knowledge content system framework, analyzing multi-source heterogeneous data of a power distribution network, defining an entity type, an attribute type, and an entity relationship, and constructing an organizational framework of knowledge of the power distribution network; data layer construction: multi-source heterogeneous data access and fusion, data preprocessing, knowledge extraction, knowledge integration, and knowledge storage and updating; and metering management application: real-time monitoring and early-warning, abnormal data troubleshooting, data quality management, and statistical analysis and decision support. According to the design of the present invention, data fusion and application integration can be performed with various service systems. The multi-source heterogeneous data of the power distribution network can be effectively integrated, the organization and management of the knowledge of the power distribution network are implemented, and the sustainable development of a power grid is promoted. By means of interactive displaying of a knowledge graph and use of a data quality management platform, abnormal metering data is automatically troubleshot.
