青州换流站高青接地极对周边油气管道影响研究

Study on the Effect of Gaoqing Grounding Electrodes on Petroleum and Gas Pipelines

介绍±800 k V扎鲁特—青州特高压直流输电工程高青接地极与邻近输油输气管道邻近的基本情况。参考国内外相关标准,给出针对工程的直流接地极对输油输气管道的电磁影响限值建议。基于现有计算方法和评价指标,进行了高青接地极对邻近埋地油气管道的电磁影响分析,分析结果可供工程前期设计参考。

This paper introduces the situation of small spacing between the Gaoqing grounding electrodes of 800 k V UHVDC transmission project from Zhalute to Shandong and the adjacent oil/gas pipeline.The limits for the electromagnetic effect on oil/gas pipeline were clarified after studying relevant domestic and international standards.Based on the current calculation method and evaluation index,the electromagnetic influence of Gaoqing grounding electrode on adjacent buried oil and gas pipelines is analyzed.The analysis results are only for engineering design reference.
