实验室环境下的智能电表载波模块通信测试

随着智能电网的建设,智能电表在国内居民用户大批量推广并已开始全面挂网运行,而作为智能电表最主要的通信模块之一的低压电力线载波模块的通信性能将直接影响使用效果。本文在实验室内模拟居民用户用电情况搭建了一个低压电力线载波测试环境,采集了6种居民用户常用的用电设备电力线噪声,并在此环境下对国内6种载波模块进行了通信成功率测试,得到了载波信号在线路衰减和用电设备噪声干扰情况下的通信数据。通过测试有助于深入了解低压电力线载波通信的特点以及为现场通信方案的选择实施与故障分析提供了参考依据。

The PLC Module Communication Test of Smart Meters Under the Laboratory's Environment

With the construction of smart grid,smart meters in the country has been promoted with high-volume residential customers and comprehensively used in the power gird,as one of the most important communication modules of smart meters,the performance of low-voltage PLC communication will affect the use effect directly.In this paper,through the laboratory simulation of residential users of electricity consumption,we will build a low-voltage PLC test environment,collect the power line noise of 6 kinds of consumer under this environment,and test the communication success rate of them.The test contributed to a better understanding of the characteristics of low voltage power line and communications solutions for on-site implementation and failure analysis will be provided as reference.
