摘　　要：针对现有的输变电设备在线监测网络在数据共享、设备通用性和网络拥塞等方面存在的问题,结合物联网技术,采用接入网和汇聚网两级通信网络结构进行变电站和输电线路的通信网络设计,通过汇聚网络的流量控制与通信流重定向解决通信网络拥塞;提出了异构双网双通道设计方法,以提高通信网络容错能力并实现了设备在线监测与资产巡检应用的紧密结合;设计了在输电线路采用无线Mesh+OPGW光纤的组合方案,并在现场进行了实测。验证结果表明:点对点远距离通信、单跳中继距离、稳定带宽和比特误码率均可以较好地满足要求,为偏远地区输电线路在线监测信号的远距离传输提供了一种有效的手段。In order to solve the problem of data sharing, equipment versatility, network congestion and other issues in the current pow- er transmission and transformation equipment online monitoring network, based on the technology of Internet of Things, this paper em- ploys a two-level communication network structure of an access network and an aggregation network to design communication network of substation and transmission lines, solving the problem of communication network congestion by the traffic control and redirection of the aggregation network. Heterogeneous double network dual channel design method is proposed to improve the communication net- work fault tolerant ability and realize a together application of on-line monitoring equipment and assets inspection. Simulation calcula- tion reveales that long distance point to point communication, single jump distance relay, stable bandwidth and bit error rate are better meet the requirements. A design scheme of wireless Mesh ＋ OPGW fiber is proposed as an effective means for transmission lines to re- alize on-line monitoring signal remote transmission, and tested and verified on site.
