Research and Implementation of Hybrid Storage Method for Multi-source Heterogeneous Data of Electric Distribution Network

The traditional relational database is difficult to efficiently store the power grid topology data with complex network relationships, which seriously restricts the application expansion of power grid topology analysis and calculation. Graph database is a new data management and analysis and calculation technology based on graph theory. The research mainly focuses on the following four aspects: first, the basic requirements of the power grid diagram database, including: the data requirements of the power grid diagram database, the functional requirements of the power grid diagram database, and the performance requirements of the power grid diagram database; the second is the research on the core technology of the grid diagram database, including: the research on the data description method of the grid diagram database, the research on the data storage technology of the grid diagram database, the research on the data modeling technology of the grid diagram database, and the research on the fast retrieval technology for the grid diagram data; the third is the development and realization of the main functions of the power grid diagram database, including: the design of the power grid diagram database system framework, the research on the development and selection of the power grid diagram database technology, and the development and realization of the basic functions of the power grid diagram database; the fourth is grid diagram database testing and application verification, including: grid diagram database testing and grid diagram database application verification.
