摘要

线路的信道模型是决定中压载波通信性能的关键因素

具有公共屏蔽的三芯中压电缆形成的信道复杂

互相耦合

传统解析计算困难且不易测量

文章首先利用模态分解方法简化三芯电缆通信信道

简化后的信道之间的信号完全解耦

有利于测量及分析;其次

通过有限元分析方法对三芯电缆的分布参数进行计算

基于文中提出的模态分解方法对计算结果进行变换

得到简化后的三芯电缆信道传输线参数。将得到的结果与实测结果对比

验证了模态分解方法以及分布参数有限元计算的正确性。

Abstract

The channel model of the underground cable is the key factor to determine the performance of medium-voltage power line communication.The three-core structure of the medium-voltage c able is complicated for traditional analytical calculation due to coupling

and not easy to measure.The article uses the modal decomposition method to simplify the communication channel of the three-core cable

the simplified channel are decoupled completely

which is beneficial to measurement and analysis.Finite element analysis is employed to calculate the distribution parameters of the three-core cable.Results are transformed to obtain the simplified three-core cable channel transmission line parameters based on the modal decomposition.The results are compared with the measured results to verify the calculation.
