基于嵌入式以太网的变电站自动化系统无缝通信体系结构

Architecture of Seamless Communication for Substation Automation System Based on Embedded Ethernet

从变电站自动化系统分层分布设计的角度出发,阐述了嵌入式以太网技术在变电站间隔层装置中的应用及实现方案。网络通信层采用光纤自愈环型以太网作为变电站网络层的主干网,在此基础上构建变电站综合自动化系统无缝通信体系结构,从而满足了该系统对网络通信的高带宽、高稳定性、高可靠性的要求,实现了智能电子设备的无缝接入。

From the viewpoint of layered and distributed design of substation automation system, the application of embedded Ethernet in bay level equipments and its implementation scheme are expounded. In network communication layer the optic fiber self-healing ringlike Ethernet is adopted as the trunk network of substation network layer, on this basis the seamless communication architecture of substation automation system is constructed. This architecture can meet the requirement of substation automation system for bandwidth, stability and reliability of network communication and realize the seamless access of intelligent electronic devices.
