信号在电力线的衰减是影响电力线通信可靠性的最主要因素之一。为了准确分析高频信号在电力线的传输中往往要受到集肤效应以及电介损耗的影响，给出一种针对三线制电力线的高频信号传输的RLCG模型。详细分析电力线RLCG模型的建立基础，对基本单元长度电力线的频率特性进行测量，并利用遗传算法对其内部参数进行辨识。以 RVV 3 G 2.5 mm2的普通家用三芯电力线为建模对象，并对RLCG模型得到的仿真结果与实际测量结果进行比较分析。实验与仿真结果表明，电力线RLCG模型在频域和时域上均能准确地反映电力线的高频传输特性，可以为电力载波通信系统的研究提供基础。

Attenuation of signal is one of the most important factors influencing power line communication’s reliability. In order to accurately analyze the high-frequency signal transmission in power line which is often affected by skin effect and dielectric effects, three-conductor power cable models which is made of RLCG circuit is proposed. The principle of RLCG model is analyzed in detail, and basis cell of RLCG parameters are deduced from the impedance measurement and identification of genetic algorithm. It models RVV 3G 2.5 mm2 power lines, and compares the simulation results with RLCG model and the measurement results. Experimental results show that RLCG model is validated in both time and frequency domains, which can provide the basis for the study of power line carrier communication systems.
