Remote integrated power grid data storage system and method

The invention discloses a remote integrated power grid data storage system, which comprises a connection module and a plurality of load balancing modules.The connection module is connected with a loadbalancing module. The connection module is used for providing an IP address to the outside, receiving a sampling data write-in request sent by an acquisition end accessing the IP address and sendingthe sampling data write-in request to the load balancing module connected with the connection module The load balancing module is used for dispersing the sampling data write-in requests to storage nodes of a connected database through a load balancing algorithm. The load balancing module which is not connected with the connection module performs hot backup, and the database performs sampling datastorage in a data cutting storage mode. According to the invention, remote disaster recovery dual cores are realized through a database middleware technology, and mass capacity storage and easy expansion are realized through a
