摘　　要：我国地缘辽阔,矿产资源分布较分散,且地质条件较复杂,部分区域建设用地较少,在对管道工程和电力工程进行建设时,通常会存在选址相近的情况,甚至部分埋地管道需与高压输电线路共用一条建设线路,因此高压输电线路必然会对管道产生电磁干扰。为了有效处理此问题,需对高压输电线路对埋地管道电磁干扰展开深入研究,并对其影响因素进行综合分析。通过数值模拟技术,对电磁干扰影响进行计算,同时需对高压输电线路故障与稳态运行期间的交流干扰状况进行评估,并将评估结果作为依据,提出各种缓解措施。China is a vast country with a relatively scattered distribution of mineral resources,and its geological conditions are relatively complex.Some regions have less construction land.In the construction of pipeline and power projects,there are usually similar locations,even some buried pipelines need to share a construction line with the high-voltage transmission line,so the high-voltage transmission line will inevitably cause electromagnetic interference to the pipeline.In order to effectively deal with this problem,it is necessary to conduct in-depth research on the electromagnetic interference of high-voltage transmission lines on buried pipelines,and comprehensively analyze its influencing factors.Through numerical simulation technology,the influence of electromagnetic interference was calculated.At the same time,it is necessary to evaluate the AC interference during the fault of the high-voltage transmission line and the steady-state operation,and propose various mitigation measures based on the evaluation results.
