Power distribution network operation data storage system and method

The invention discloses a power distribution network operation data storage system and method. The system comprises a data processing module, a data server cluster, a metadata server cluster and a central switch, the data processing module is used for filtering to-be-processed distribution network operation data to obtain target data, and sending the target data to the metadata server cluster and the data server cluster through the central switch; and the metadata server is used for determining target metadata corresponding to the target data on the basis of a data storage instruction when the data storage instruction is received, and storing the target data to the data server cluster on the basis of the target metadata. Based on the technical scheme, the problems that in the operation process of the power distribution network, the storage efficiency of the acquired operation data of the power distribution network is not high, and the storage safety of the data of the power distribution network is low are sol
