摘要

高压直流输电线路(HVDC)单极经大地回路运行产生的地表电位分布对交流输电系统有负面影响。实际情况下的土壤结构是非常复杂的。本文阐述运用目前国内外接地计算较多采用的CDEGS软件包中的MALZ模块对复杂土壤模型进行计算,分析湖泊、大型金属管道等对电位分布的影响,以总结其对地表电位分布的影响规律。
The ground surface potential,arisen from the single-pole ground-retum mode operation of HVDC transmission line,may have negative effects on AC power systems.The real soil structure is very complicated,This paper illustrates the application of worldwide popular software CDEGS in various soil structures,and case studies are carried out by employ- ing it.Influence factors such as the grounding electrodes and soil structures etc.are also discussed to summarize the characteristics of the ground surface potential distribution.
