Electric power measurement data management system and method

The invention relates to a power measurement data management system and method. The system comprises a management center and a plurality of edge units. The edge unit comprises a data acquisition module, an edge database, an edge calculation module and an encryption module; the edge unit constructs an edge block network based on a block chain technology, comprises a central node and a plurality of lightweight block chain nodes, and deploys the lightweight block chain nodes to the data acquisition module by using an edge computing architecture of Hyperdger Fabric; a data synchronization mechanism is established between the edge database and the central node, and the encrypted data is synchronized to the central node; the management center deploys a management node based on the block chain technology, and is used for monitoring and managing the whole block chain network. According to the method, power edge measurement data management is realized based on the block chain, the security and credibility of the data
