The invention provides a real-time database monitoring system and method for an intelligent power grid dispatching control system, which relate to the technical field of the database. The system comprises a mode monitoring module, a data monitoring module and a middle layer monitoring module. The mode monitoring module is used for monitoring the correctness of the mode of the real-time database and the consistency of the mode of the real-time database and the mode of the relational database. The data monitoring module is used for monitoring the consistency of the data of the real-time databaseand the data of the relational database, and the consistency of the data between the host and standby real-time databases. The middle layer monitoring module is used for monitoring the running stateof the middle layer. The real-time database monitoring system and method of the intelligent power grid dispatching control system provided by the embodiment of the invention can automatically monitorthe real-time database, improve the operation and maintenance efficiency, and effectively improve the operation stability and safety of the real-time database.
