The invention discloses an energy SCADA massive data distributed processing system and a distributed processing method thereof. The energy SCADA massive data distributed processing system comprises a client, a real-time communication node, a management server and a distributed data server which are sequentially connected, wherein the real-time communication node comprises a real-time library and a configuration library; the management server comprises a primary management server and a standby management server; and the distributed data server comprises a plurality of primary storage nodes and a plurality of standby storage nodes. According to the energy SCADA massive data distributional processing system, attribute information, such as a path, time and the like, of storage files of massive historical data and the data are separately stored, the attribute information of the files are stored on the management server, data information is stored on the nodes of the data server and data fragments are stored on a plurality of different servers in a form of binary files. Due to the reason that the data information is stored on a plurality of servers, the servers can transmit the data outwards in parallel, the larger the number of the data servers is, the higher the access efficiency is, and the storage and access problems of current SCADA massive historical information are solved.
