Constructing Knowledge Graph from Big Data of Smart Grids

The big data of grid is characterized by a large amount of data and complex structure. There are many kinds of grid equipment in the grid and smart grid, and their relationships are complicated. Therefore, it is necessary to analyze and visualize the grid equipment information and relationships reasonably to improve and develop the grid information system. The power equipment information in the data center is relatively complex and does not reflect the relationships between the equipment well. In order to manage and use grid equipment information better, we propose a grid equipment knowledge graph to solve the problem of "information island" of smart grid equipment. A knowledge graph has been constructed according to the grid equipment big data from the grid domain data center, which reflects the multifaceted information of the equipment as well as inter-equipment relationships.
