Analysis on the Simulation of Electromagnetic Radiation in PLC Networks

阐述了电力线载波通信参数和存在的电磁辐射问题,并就辐射产生的原因与影响进行了分析与探讨.提出采用动态补偿信号来抑制室内PLC电磁辐射的方法,并通过MATLAB软件模拟计算室内PLC的电磁辐射环境,得到加载动态补偿信号可以降低PLC电磁辐射60 dB的结果.

This paper discusses the electromagnetic radiation parameters in the PLC networks, and the origin and influence of the radiation are analyzed. An improvement technique for the reduction of emissions from PLC networks is proposed. With MATLAB numerical simulation environment indoors, the technique is shown to reduce the radiated electric field up to 60 dB.
