Abstract:

Integrated and interconnected bulk power grid puts forward new challenges to the global and real-time data of the existing dispatching automation system. This paper puts forward the architecture and construction principle of the power grid dispatching an control real-time data platform. On this basis, some key technologies such as online synchronization of power grid model, distributed data collection and processing, large-scale parallel state estimation, unified service of real-time data are studied. And single-point acquisition and sharing of real-time data in the entire network are realized based on automatic model synchronization without maintenance. The power grid real-time dispatching and control data platform is piloted in the national electric power dispatching and control subcenter. The application results show that the proposed scheme improves the globality, real-time capability, operation and maintenance efficiency of real-time data aggregation, and it could provide comprehensive, real-time and accurate snapshots of real-time data and state estimation data in the entire power grid for power grid analysis and decision-making applications.
