摘要
为了解决变频器群控与配电保护协同运行中多节点并发冲突、电磁干扰及数据优先级调度不合理等通信问题,设计了一种面向变频器群控与配电保护协同的通信系统。系统采用基于时间敏感网络(Time-Sensitive Networking,TSN)的确定性通信调度技术、工业环境高可靠抗干扰传输技术、面向协同控制的动态数据优先级与流量整形技术等核心技术,构建了涵盖现场设备层、通信网络层和控制管理层的完整通信架构。测试验证表明,系统在多节点并发工况下实现了毫秒级确定性传输,在强电磁干扰环境中保持了极低误码率,紧急保护指令能够优先快速传递。
To address communication issues such as multi-node concurrency conflicts,electromagnetic interference,and unreasonable data priority scheduling in the coordinated operation of inverter group control and distribution protection,a communication system tailored for the coordination of inverter group control and distribution protection has been designed.The system adopts core technologies such as deterministic communication scheduling technology based on Time—Sensitive Networking(TSN),high reliability anti—interference transmission technology in industrial environments,and dynamic data priority and traffic shaping technology for collaborative control,to construct a complete communication architecture for the field device layer,communication network layer,and control management layer.Test verification shows that the system achieves millisecond level deterministic transmission under multi node concurrent conditions,maintains extremely low error rates in strong electromagnetic interference environments,and can prioritize rapid transmission of emergency protection instructions.
