In order to adapt to the architecture of the horizontal integration and vertical interaction

and satisfy the demand to the real-time database for large capacity

high efficiency and high security

the real-time database is necessary to proposed for the smart grid dispatch and control system. This paper first analyzes the demand to the real-time database. Then the real-time database architecture and the technologies are introduced including large volume and application extension

high efficiency access

security guarantee

model management and real-time synchronization. The test in the paper proves that the efficiency of the real-yime database improved apparently than the conventional system

and the security of data access could be guaranteed. The real-time database provides the firm basis for various applications ensures the stable operation of every level in of the dispatch and control system and supports the smart grid construction effectively.
