摘要

直流输电线路在运行中会发生电晕现象

由此产生的离子流场是环境问题关注的焦点。基于有限元的离子流场计算方法由于更符合线路实际情况且计算精度较高

受到了国内外学者的重视。为系统阐述基于该方法的国内外研究成果

并为今后该领域的研究提供有益参考

文中重点分析了现阶段基于有限元的二、三维离子流场计算方法的优缺点

同时还分析了建筑物和人体对离子流场的影响研究现状。通过对比分析认为:基于有限元三维离子流场的计算方法将会在今后的实际工程中发挥重要作用。最后为对直流线路或者交直流混合线路电磁环境进行全面而准确的评估

应当加强地形及天气方面等的影响研究。

Abstract

DC transmission lines generate corona

resulting in ion flow field.This kind of ion flow field has become one of the focuses in research of environmental problems.The finite element based calculation method of the ion flow field has attracted more and more attention because it accords with actual situation of transmission lines and has higher calculation precision.This paper expounds the corresponding researches both in China and abroad in order to provide a reference for the future research in this domain.In the paper

the advantages and disadvantages of the finite element based two-and three-dimensional calculation methods of ion flow field are analyzed

and the researches on the effects of building and human body on the ion flow field are discussed.Contrastive analysis indicates that the three-dimensional calculation method of ion flow field will play an important role in engineering.In addition

it is suggested that more attentions should be paid to the influences of terrain and weather for comprehensive and accurate assessment of electromagnetic environment for the DC or AC/DC hybrid transmission lines.
