In order to realize the data sharing and interoperability of application system, as well as the integrated technical support system for regional power grid scheduling, this paper developed the technical support platform of scheduling, which taken the common information model (CIM) as the core model and had the graphics interoperability function of panoramic visualization, based on the update of energy management system (EMS). This technical support platform can realize the unified management of models and parameters for power grid and the sharing of basic resources in Nanchang, which can effectively support the construction and development of intelligent scheduling system for the regional power grid in Nanchang.
