Aiming at the problems of uncoordinated source-grid-load in rural power grids, the number and types of distributed power sources, and the low level of distribution automation, this paper develops a big data analysis platform for rural smart grids.The overall architecture of the system is divided into a data source layer, a data integration management layer, and a business application layer, and the system software and hardware functional solutions are given.The deployment method of smart grid big data analysis platform and the principle of technical data transmission are described.Finally, the theme of the platform is modularized, and the overall function modules of the platform, green energy theme modules, safety operation and maintenance theme modules, and reliable transmission and transformation theme modules are described.
