In order to study the ion flow field problem near the ground of UHV DC transmission lines, the BPA method is applied to solve the ion flow field of bipolar DC transmission lines. The synthetic electric field is solved combined with the nominal electric field calculated by the successive image method. The ion flow field and synthetic electric field problems of ±800 kV DC transmission lines are calculated using the BPA method, and the effects of erection height, interelectrode distance, and sub-conductor radius on the synthetic electric field of UHV DC transmission lines are analyzed. In addition, the power-line method for solving the synthetic electric field strength is compared. The results show that the BPA method is accurate and effective in solving the ion flow field, and the calculation efficiency is greatly improved. Increasing the height of the wire erection and increasing the radius of the split sub-conductor can improve the electromagnetic environment near the ground, while reducing the interelectrode distance can reduce the synthetic electric field intensity near the ground, but the effect is not obvious.

为研究特高压直流输电线路地面附近的离子流场问题,应用BPA法求解双极直流输电线路离子流场,结合逐次镜像法计算的标称电场,进而求得合成电场,并利用该方法计算了±800 kV直流输电线路的离子流场与合成电场问题,分析了导线对地高度、极间距、子导线半径对特高压直流输电线路合成电场的影响。此外,还对比了求解合成电场强度的电场线法。结果表明,BPA法求解离子流场准确有效,且计算效率大大提高;提高导线架设高度和增加分裂子导线半径均可改善地面附近电磁环境,而减小导线极间距能够降低地面附近的合成电场强度,但效果不明显。

为研究特高压直流输电线路地面附近的离子流场问题,应用BPA法求解双极直流输电线路离子流场,结合逐次镜像法计算的标称电场,进而求得合成电场,并利用该方法计算了±800 kV直流输电线路的离子流场与合成电场问题,分析了导线对地高度、极间距、子导线半径对特高压直流输电线路合成电场的影响。此外,还对比了求解合成电场强度的电场线法。结果表明,BPA法求解离子流场准确有效,且计算效率大大提高;提高导线架设高度和增加分裂子导线半径均可改善地面附近电磁环境,而减小导线极间距能够降低地面附近的合成电场强度,但效果不明显。

In order to study the ion flow field problem near the ground of UHV DC transmission lines, the BPA method is applied to solve the ion flow field of bipolar DC transmission lines. The synthetic electric field is solved combined with the nominal electric field calculated by the successive image method. The ion flow field and synthetic electric field problems of ±800 kV DC transmission lines are calculated using the BPA method, and the effects of erection height, interelectrode distance, and sub-conductor radius on the synthetic electric field of UHV DC transmission lines are analyzed. In addition, the power-line method for solving the synthetic electric field strength is compared. The results show that the BPA method is accurate and effective in solving the ion flow field, and the calculation efficiency is greatly improved. Increasing the height of the wire erection and increasing the radius of the split sub-conductor can improve the electromagnetic environment near the ground, while reducing the interelectrode distance can reduce the synthetic electric field intensity near the ground, but the effect is not obvious.
