This paper proposes a new perspective for the vertification of grid models between the active and standby systems of the power dispatching automation, and the latter is integrated with the real-time database. This paper analyses the technologies of the grid model verification between the active and standby system based on the key technologies of the relational database and the real-time database. It discusses in detail the changes in the data storage structure of grid models, the technological architecture of the verification of grid models and the validation process. The research results have obtained practical applications in the smart dispatching system of power systems of Suzhou. Practice shows that the technologies proposed significantly improve the efficiency of grid model verification between the active and standby system, as well as provide support for lean power dispatching.
