面向智能变电站通信的全光交换技术应用

All optical-switching technology in transformer substation network

网络技术的发展促进了传统变电站向智能变电站的演进,变电站内的各传感器、保护、测控、计量等设备通过交换机完成变电站内的实时信息交互,由于变电站内的电气设备对时延要求极为苛刻,光—电—光转换式交换机应对突发式数据交换时难以满足要求。针对变电站通信业务的具体特点和时延要求,提出了面向智能变电站的全光交换网络架构,避免了传统交换机的光—电—光转换操作,实现从保护装置到智能终端、合并单元的快速、可靠通信传输,可作为目前要求苛刻的变电站网络的拓扑结构。

The development of network technology promotes the development of the traditional substation to the smart substation, where all devices can exchange the real-time information via the switch in the smart substation. In view of the strict time delay requirement of substation communication service, a full optical switching network architecture for smart substation was proposed, which avoided the operation of optical, electric and optical conversion, and realized the fast and reliable communication between the protection device and the smart terminal as well as the merging unit.
