摘要
针对广域保护系统对信息交换类型和交换方式的不同要求,讨论了基于IEC61850的广域保护系统通信服务模型,主要解决通信一致性和不同装置之间的互操作性问题,并从上层确保数据通信延时和可靠性满足广域保护系统的要求。介绍了通用变电站事件GSE的报文结构和通信机制,提出用GSE中的GSSE传输状态量信号、用采样测量值传输类模型传输模拟量的观点和一般方法。
Information exchange style and mode for wide area protection system are studied. Communication service model based on IEC 61850 is discussed. The aim is to solve the problem of communication consistency and co-operation between different devices. The method to ensure communication speediness and reliability in upper layer is also studied. Message structures of GSE and communication mechanism are discussed. The viewpoint and general method about transmitting digital message by GSE, transmitting analog message by SVA are proposed.
