摘要
为研究雷击高压交直流同塔输电线路对并行输油输气管道的电磁干扰,以±800 kV/500 k V同塔四回架空输电线路与油气管道平行架设为背景,通过ATP-EMTP软件搭建同塔四回输电线路、管道并列运行模型及雷电流模型,并通过仿真计算,分析了雷击点位置、土壤电阻率、线路架设高度、线路与管道并行间距、管径大小等因素对高压线路走廊内平行铺设管道的电磁影响。结果显示:雷击点位置和线路与管道并行间距对管道上感应电压值的干扰较为严重;土壤电阻率线、路架设高度、管径大小等因素的对管道的干扰较小。此结论可为交直流并行线路走廊内铺设油气管道相关工程提供一定的建设参考价值。
In order to study the electromagnetic interference caused by lightning strike on high voltage AC/DC transmission lines on the same tower to parallel oil and gas pipelines,based on the parallel erection of( ± 800 kV/500 kV) four-circuit overhead transmission lines on the same tower and oil and gas pipelines,an equivalent model of parallel operation of four-circuit transmission lines and pipelines on the same tower is established by ATP-EMTP software. Through the simulation calculation,the electromagnetic influence of the lightning strike point position,the soil resistivity,the height of the line erection,the parallel spacing of the line and the pipeline,and the diameter of the pipe on the parallel laying of the pipeline in the high-voltage line corridor are analyzed. The results show that the location of the lightning strike point and the parallel spacing between the pipeline and the line are more serious to the induced voltage value on the pipeline;the interference ofthe soil resistivity,the line erection height and the diameter of the pipeline is less. This conclusion can provide a certain reference value for the construction of oil and gas pipelines in the AC and DC parallel line corridor.
