ROADM站型探析及其在电力传输网中的应用

Analysis of ROADM Station Types and Application in Power Transmission Network

电力信息通信业务的发展,对电力光传输网的灵活调度能力、业务适应能力和安全可靠性提出更高要求,文章旨在提出一种能满足其要求的可重构光分插复用器(Reconfigurable Optical Add-Drop Multiplexer,ROADM)网络架构,助力电力光传输网的优化和演进。通过对ROADM站型的分析和比选,初步确定各ROADM站型适合的网络节点类型。通过对电力光传输网各节点的分类分析,初步确定核心层、骨干层、接入层的节点类型和覆盖范围,进一步与ROADM站型进行匹配,提出ROADM网络架构。最后介绍ROADM网络规划的光功率预算策略。

With the development of electric power information and communication services,higher requirements are put forward for the flexible dispatching ability,service adaptability and security reliability of power optical transmission network.This paper proposes a ROADM network architecture that can meet the requirements,which will help the optimization and evolution of power optical transmission network.Through the analysis and comparison of ROADM station types,the network node types suitable for each ROADM station type are preliminarily determined.Through the classification and analysis of each node in the power optical transmission network,the node types and coverage of the core layer,backbone layer and access layer are preliminarily determined,and the ROADM network architecture is proposed by matching with the ROADM station type.Finally,the optical power budget strategy of ROADM network planning is introduced.
