摘　　要：配电系统是电力系统的重要组成部分,在积极稳妥推进“碳达峰、碳中和”和建设新型电力系统的背景下,配电系统将接入越来越多的分布式资源,形态特征将发生很大改变。准确地掌握配电场景的电磁环境和无线传播特性,对高效实现配电系统的无线专网和行业现场网系统规划、物理层设计和算法优化、点位部署,进而实现可靠实时通信,将起到至关重要的作用。针对配电场景下无线信道的大小尺度衰落特性进行了测量分析和传播模型建模,并且经验证该模型与实测吻合,对今后类似场景的电力无线专网等网络的系统规划、工程设计等有一定参考意义。The distribution system is an important part of the power system. In the context of the “carbon peak & carbon neutral” goal and the construction of new power system, the electricity distribution system will be connected to more and more distributed resources, and the morphological features will be greatly changed.An accurate grasp of the electromagnetic environment and wireless propagation features of power distribution scenarios will play a crucial role in efficiently realizing wireless private network and industry field network system planning, physical layer design and algorithm optimization, point deployment, and then reliable realtime communication for power distribution systems. In this paper, measurement analysis and propagation modeling are conducted for the size scale fading features of wireless channels in power distribution scenarios.The model is verified to be in agreement with the actual measurement, and it has some reference significance for the system planning and engineering design of power wireless private networks and other networks in similar scenarios in the future.
