The invention discloses a two-stage deployment-based power grid control model center system. The system comprises a national power grid control model center system and a provincial power grid control model center system, wherein the national power grid control model center system is used for managing storage and sharing of power grid models of 220kV and above in a whole grid; the provincial power grid control model center system is used for managing storage and sharing of power grid models of 10kV and above in a provincial range; the national power grid control model center system and the provincial power grid control model center system comprise model maintenance modules, graphic editing modules, network modeling modules, graphic model checking modules, auditing process modules, version management modules, model subscription and release modules, and safety management modules. According to the two-stage deployment-based power grid control model center system, source ends of the power grid control models are maintained in a responsibility division manner; the whole grid is shared as needed; and the timeliness, accuracy and consistency of model maintenance and sharing are improved.
