摘要

自20世纪80年代开始，我国配电网迅速发展，其覆盖面积广，架构十分稳定，给电力线载波通信提供了便利稳定的硬件条件。但是，目前在电力线载波通信建模领域，由于对趋肤效应考虑较少，参数建模不准确，配电网络特征阻抗无法准确计算，无法高效利用电力线网络进行准确载波信号传输。为了解决参数模型准确性低的问题，选用铠装电缆对其电路参数和信号衰减的传播常数进行数学建模，并通过有限元仿真软件对构建参数模型的准确性进行验证，随后分析其信号传输特性，对比仿真结果与本文模型计算结果，验证了本文建模方法的有效性以及实用性。

Abstract

Since the 1980s

China's distribution networks have rapidly developed

covering a vast area and featuring a stable structure that provides favorable hardware conditions for power line carrier communication.However

in the field of power line carrier communication modeling

the skin effect is often overlooked

leading to inaccurate parameter modeling and an inability to compute the characteristic impedance of distribution networks accurately

thus hindering the efficient transmission of carrier signals.To address this issue

this paper selects armored cables to mathematically model their circuit parameters and the propagation constants for signal attenuation.The accuracy of the constructed parameter model is validated using finite element software COMSOL.Subsequently

the signal transmission characteristics are analyzed

and a comparison of simulation results with the calculated results of this model verifies the effectiveness and practicality of the proposed modeling approach.
