Real-Time Data Transmission Supporting Network Segmentation Environment

Network separation policies in power systems enhance security but limit real-time data integration between FA and OA networks, reducing operational efficiency and delaying responses to outages and faults. Conventional file-based data exchange methods are insufficient to ensure real-time synchronization and data consistency. This paper proposes a real-time data transmission and synchronization framework for heterogeneous networks in a network-separated environment, ensuring data consistency and ordering. The proposed system extracts incremental changes from the source database in real time, transmits them securely, and validates, orders, and synchronizes the data at the receiver. The results demonstrate that the proposed approach enables reliable real-time data sharing under network separation constraints, thereby improving the efficiency and stability of power system operations.
