摘要

本文给出了实际高压直流电晕输电线路地面电场强度E和电流密度J的计算和实测(缩比模型)分布。本文利用文献1的迭代方法求解了单极线情况下E和J的电晕方程。由于在双极线下，只有两个单极区域(负极和正极)在地面上存在，因此同样的方法也用于双极情况。计算得到的E和J曲线与实测曲线吻合较好。E和J曲线的最大值随各参数的变化关系可用于高压直流输电线路的设计和分析。

Distribution of ion flow field quantities in air under HVDC transmission lines

This paper presents computed and measured (in a reduced-scale model) distributions of electric field strength E and current density J at ground level under practical HVDC transmission lines in corona. The iterative method of Ref. 1 is used to solve the corona equations for E and J in the case of unipolar lines. Since under bipolar lines, only two unipolar regions (negative and positive) exist at the ground level, the same method is used for the bipolar case also. Good agreement is observed between the computed and measured profiles of E and J. Mathematical relations for maximum values of E and J as function of various parameters can be utilized in design and analysis of HVDC transmission lines.
