摘要:
随着电力信息化的不断发展,电力企业构建大容量、高带宽的OTN传送网络已成为发展趋势。本文结合广东电力OTN光传送网的工程特点,从组网结构、交叉技术和网络保护展开分析,在组网结构上选择核心层、骨干层、接入层的三层结构,骨干层随电网架构通过OPGW组成MESH网,骨干层和核心、骨干层和接入层之间不少于2点互联,提高可靠性的同时控制投资。本文给出了设备交叉技术、网络保护的技术选择因素,为电力系统OTN光传送网的建设提供参考。最后,本文给出了使用OTN空闲波道作为应急波道的应用案例,为处于台风区的广东电力提供应急保障。
Abstract:
With the continuous development of electric power information technology, the construction of large capacity, high bandwidth OTN network by electric power enterprises has become a trend. According to the Guangdong power OTN network's engineering characteristics, this papar gives an analysis on network structure, cross technology, network protection, and it selects a three-layer structure including the core layer, backbone layer and access layer, the backbone layer uses OPGW to build MESH network based on power grid structures. There are no less than 2 connections between backbone layer and core layer, the same to backbone layer and access layer, which improves the network reliability besides controling the investment. This paper also gives the technology choice of the cross technology and the network protection, giving reference to OTN network construction by electric power enterprises. At the end, this paper gives an application case using OTN idle channels to provide emergency support for Guangdong power grid, which in the typhoon prone area.
