摘要:
导线表面电场是特高压直流(UHVDC)输电线路无线电干扰、可听噪声以及电晕损失的决定因素,为此准确计算导线表面电场强度显得格外重要.国内外对表面电场的影响因素分析较少,本文以模拟电荷法为基础,以每个子导线内部设置12个模拟电荷为例,针对线路的分裂导线数、子导线分裂间距、子导线横截面积、导线对地高度及极导线间距等影响因素进行分析.运用MATLAB语言编写程序，对模型进行计算仿真,得出每个变量对表面电场的定量影响,为工程架设中选择导线结构参数提供重要的理论依据．
Abstract:
Conductor surface electric field strength is the determining factor for radio interference,audiblenoise and corona loss of ultra-high voltage direct current(UHVDC)transmission line,so it is particularly im-portant to accurately calculate the conductor surface electric field strength. The study of factors on the surfaceelectric field at home and abroad is more less. Therefore the investigation is carried out on the influence of sub-conductor number,sub-conductor cross section,split spacing and conductor height on the conductor sur-face maximum field strength,which used charge simulation method by set 12 charge simulation in each sub-conductor. The program is written in MATLAB language to calculate and simulate,and each variable affectingon surface electric field strength is resulted quantitatively,which provides an important theoretical basis for en-gineering construction how to select the structural parameters of conductor.
