中文摘要:无线通信是当前配电网通信的重要组成部分。首先分析了配电网各类业务对TD-LTE无线专网性能的需求,然后在TD-LTE无线专网实验平台上,测试了传输时延和时延抖动两项网络性能指标。实验测试及分析结果表明,在正常业务量状态下,TD-LTE无线专网可以满足配电网业务传输要求,但在用户过载或网络拥塞时,则难以提供可靠的网络通信服务。文章最后给出了保障配电网TD-LTE无线专网可靠性的几点建议。

TD-LTE Specialized Network for Distribution NetworkService Transmission Performance Test and Analysis
Abstract:Wireless communication is an important part of current distribution network communication. Firstly,this paper analyzes the demand of distribution network for TD-LTE wireless network performance,then on the experimental platform of TD-LTE wireless network,two performance indexes of transmission delay and delay jitter are tested. Experimental tests and analysis results show that TD-LTE wireless network can meet the transmission requirements of distribution network under normal business conditions,but it is difficult to provide reliable network communication services when users overload or network congestion. Finally,the paper gives some suggestions to ensure the reliability of the distribution network TD-LTE wireless network.
