摘要

提出了一种基于 Q3D 的宽带电力线信道建模方法。首先利用 Q3D 软件提取电力线信道的单位长度参数RLGC，然后根据提取的RLGC参数计算电力线信道的ABCD传输矩阵，最后根据ABCD矩阵求出电力线通信信道传输函数和输入阻抗的幅频响应和相频响应。利用所提方法，建立基于3 mm×4 mm三芯对称电缆的宽带电力线通信信道模型，并在30 kHz~100 MHz频带范围内与实测数据进行对比。结果表明，仿真结果能够很好地符合测量结果，本文所提方法能够快速、准确地建立电力线宽带信道模型，对于电力线通信信道特性的研究以及工程实践具有重要意义。

Abstract

A method of broadband power line communication (PLC) channel modeling based on Q3D extractor was proposed. The per unit length RLGC parameters of PLC channel was extracted by the Q3D extractor. Then

the ABCD transfer matrix of power line channel was calculated based on the extracted RLGC parameters. Finally

the amplitude and phase frequency responses of the channel transfer function and input impedance were obtained by using ABCD matrix. Based on the proposed method

a broadband PLC channel model for 3 mm×4 mm symmetrical cable was set up. The calculated results show that the simulated results fit the measured results well. The proposed method can quickly and accurately establish the broadband PLC channel model

which is of great significance for studying the characteristics of PLC channel.
