摘要
配用电网最后一千米主要指0.4 k V及用户室内部分。为了给配用电网最后一千米低压集中抄表业务提供稳定、可靠的通信通道,文章提出一种基于正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)调制方式的新一代载波技术通信方案,并无缝接入10 k V配网自动化的通信接入网,形成了智能配用电网最后一千米通信的综合解决方案。重点介绍了G3-PLC标准的性能特点,并通过仿真分析该标准下的综合通信解决方案的业务轮询时间。结果表明,综合通信解决方案能很好地满足低压集中抄表业务的通信需求。
In order to provide a stable and reliable communication channel for low-voltage meter reading system in the last mile in distribution network, this paper proposes an integrated communication solution based on OFDM modulation, which can connect the low-voltage meter to the 10 k V distribution automation network seamlessly. This paper introduces the performance characteristics of G3-PLC standard, and analyzes the service polling time through simulation. The simulation results show that this integrated solution can well satisfy the communication demand of low-voltage meter reading system.
