摘要
为研究高压架空线路发生单相接地故障对附近输油输气管道的电磁影响,以220 kV同塔双回架空线路与输油输气管道并列运行为背景,利用电磁暂态仿真软件ATP建立同塔双回输电线路及油气管道等效时域模型,分析了故障点位置、并列运行部分杆塔接地电阻大小、导线高度,管道与杆塔中心线水平间距、管径大小等因素对高压输电线路附近油气管道电磁感应电压的影响。结果表明:油气管道的电磁感应电压受接地点故障位置、杆塔接地电阻以及管道距杆塔中心线水平间距的影响较大;导线高度、管径大小等因素对管道上产生的电磁感应电压影响不明显。得出的结论可以为高压输电线路与输油输气管道同走廊建设提供理论指导。
In order to study the electromagnetic influence due to Single-phase earth fault on the nearbypetroleum/gas pipelines,taking a 220 kV double circuit transmission line on the same tower for example.The time domain simulation calculation model is established by the electromagnetic transient simulationsoftware ATP,Which was used to analyze the effects of fault position,height of transmission line,groundresistance of towers,horizontal spacing,and diameter of pipe for the interference of oil-gas pipeline inthe vicinity of the high voltage transmission line.The results show that electromagnetically induced volt-age of oil and gas pipeline is obviously affected by fault position,ground resistance and horizontal dis-tance,while the lead height and pipeline diameter have little impact on the induced voltage.The conclu-sion can provide theoretical guidance for the laying of gas pipeline in the vicinity of the high voltage line.
