With the further development of digital grid construction, the scale of electrical energy data continues to expand, and the demand of data application is also increasing. Considering the limitations of the original application architecture of the electrical energy data platform of China Southern Power Grid, this paper designs a full stack and distributed architecture for large-scale electrical energy data, and applies it to the electrical energy data platform of China Southern Power Grid. The architecture integrates the distributed technology of computing, storage, message queue and application, which can achieve real-time data collection, unified management and unified application of electrical energy data. It supports the development of electricity consumption analysis, line loss management, power quality monitoring and other businesses of China Southern Power Grid, and improves the ability of analysis, application and management of electrical energy data.
