摘要
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 mode-ling 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.关键词
