摘要

当暂态高频信号在交联聚乙烯（XLPE）电缆中传播时

导体的集肤效应和半导电层的频变效应是导致高频信号衰减和分散的主要原因

而以往的整数阶电缆模型往往忽略内、外半导电层的频变效应

影响暂态分析的准确性

因此建立一个电缆分数阶宽频模型对于分析高频信号有着重要的意义。文中首先测量了电缆半导电层的相对复介电系数

使用Cole-Cole模型进行拟合后

利用拟合模型和圆柱形电容的计算公式推导出电力电缆内外半导电层的分数阶导纳参数。根据Boogs提出的径向电缆模型

建立起同时考虑电缆集肤效应和半导电层频变效应的分数阶电缆模型

基于该模型分析了电缆中高频信号的传播规律。最后

通过分数阶传输线方程的频域求解

将计算波形与PSCAD仿真结果以及实验测量波形进行对比

验证了本模型的精确性。

Abstract

When the transient high frequency signal is transmitting in cross-linked polyethylene（XLPE） cables

the skin effect of conductor and the frequency change effect of semi-conductive layer are the main causes of the attenuation and dispersion of the high frequency signal.In the past

the model of cables often ignored the frequency effect of the inner and outer semiconducting layers

which affected the accuracy of the transient analysis.Therefore

the establishment of a cable fractional broadband model is important for the analysis of high frequency signals.In this paper

the relative complex permittivity of the semi-conductive layer is measured first.After fitting the data with the Cole-Cole

the fractional admittance parameters of the inner and outer semi conductive layers of the power cable are derived by using the fitting model and the cylindrical capacitance formula.According to the radial cable model proposed by Boogs

a fractional order cable model

which both considers the skin effect and the frequency change effect of the semi conductive layers is set up.Based on this model

the propagation characteristic of the high frequency signal in the cable is analyzed.Finally

solving this model in the frequency domain

the calculated waveform is compared with the simulation results of PSCAD and experimental measurement waveform

the accuracy of the model is verified.
