摘　　要：为了适应输变电设备物联网广泛感知及海量信息处理,提出一种适用于输变电设备物联网在线监测和设备资产管理系统的通信网络结构和实现方案,所提出的扁平式网状网结构支持了现场信息的采集点分散和分布式处理。在网络结构中增加汇聚层功能实体以实现物联网通信设备及通信流的有效管控,并且在现场组网实现方案中采用有线和无线双通道异构组网技术,提升了系统容错能力。依照IEC61850标准测试了通信系统的性能和功能,结果表明:在广播风暴场景中,传统网络近于瘫痪;而在该网络结构和组网实现方案中,广播风暴场景下的网络时延最大87.93 ms,因此在满足IEC61850标准所规定的时延和带宽要求前提下,比传统方法更有效地保障了重负载网络性能和网络容错能力,满足输变电设备物联网信息采集和处理的通信质量保障需求。We proposed a communication network architecture and its implementation scheme which are suitable for things of internet （IOT） to adapt on-line monitoring and equipment assets management of power transmission and its distribution equipment. The flat mesh framework supports the decentralization of information collection points in Field Area Network and distributed processing between processors. By introducing the function entity of convergence layer, the scheme realizes the management and control of IOT communication equipment and communication flow when the double-channel heterogeneous networking framework of wired network and wireless network was designed to enhance the fault-tolerant capability of the system in the field implementation scheme. The function and performance of the IEC61850-based communication system were measured. The test shows that, in the broadcast storm scene, the traditional network almost collapses; however, in the new network structure presented in this paper, the network delay under the maximum of 87.93 ms reveals that, based on the communication network architecture, the performance of network and its fault-tolerant capability are effectively guaranteed compared with traditional network on the premise of meeting the latency and bandwidth requirements proposed in IEC61850 standard. Accordingly, the communication network framework can satisfy the requirements of communication quality assurance in information collection and processing of IOT for power transmission and its distribution equipment.
