Secondary System Data Flow Planning and Design for Substations

To address the problem of data duplication and isolated data caused by the binding of substation-specific data to equipment and the independent construction of various systems, this article focuses on the interaction data flow between substation equipment. Based on the differences in real-time data, data structure, and processing performance indicators, the data transmission path is optimized. The existing multi-end duplicate data collection is divided into partitioned transmission. By using cross-zone real-time bus synchronization technology, the data of primary and secondary equipment as well as auxiliary equipment are shared comprehensively at the station control level, supporting the integration and optimization of substation secondary system functions and equipment. This achieves the integration of primary and auxiliary equipment for comprehensive monitoring.
