Power grid data security management system

The invention discloses a power grid data security management system, relates to the technical field of data management, and solves the problems that data are not encrypted in a transmission process, so that the data are easily stolen by external personnel in the transmission process, and the data are lost. Comparing the data features with a preset lexicon, locking the capacity ratios of words with the same features, then determining a maximum group of capacity ratios from a plurality of groups of generated capacity ratios, if the same capacity ratios exist, randomly selecting a storage area, sequentially confirming the storage area, and storing the storage area in the storage area. The power grid data with the same characteristics are stored in the same storage area, it is guaranteed that the power grid data can be effectively classified in the storage process, when data selection or calling is conducted, convenience is brought to subsequent personnel when data extraction is conducted, and the overall effect
