    Abstract:

    As the integration characteristics of power grid operation become prominent, the application business links between various levels of regulatory agencies are becoming increasingly close, and the demand for information sharing and data interaction is becoming more and more urgent. In order to achieve integrated and coordinated operation, the power grid dispatch and control system needs to interact with a large number of real-time data and non-real-time data between different regulatory agencies and business applications. However, the current technical scheme is mainly aimed at the data interaction between real-time services, and there is no universal data interaction mechanism in quasi-real-time/non-real-time business scenarios. Aiming at the above problem, this paper puts forward the regulation of business oriented, quasi-real-time/non-real-time data across institutions and across the safe zone, cross-platform integrated exchange of architecture, the establishment of a canonical data interaction processes and operation mechanism based on task, to realize unified management of data interaction process. At present, the research results have been applied in engineering to support the integrated and coordinated business of provincial, regional dispatch centers and substations.
