In order to solve the problem of processing performance of large-scale real-time data in power dispatching and control systems

a cluster based distributed real-time database is designed

which uses distributed technologies to achieve massive data storage and cluster technologies to achieve uniform data access and management. Key technologies of cluster based real-time database are discussed including distributed storage

distributed data location and distributed data access. The problem of flexible slicing

large-scale data storage and fast data locating of real-time data in a power dispatching and control system is also solved. Testing and on-site system verification prove that the cluster based distributed real-time database system is able to achieve high efficient data access and the condition of high reliability of the system is ensured.
