摘要
随着我国能源公共通道的发展,交流架空输电线路对邻近埋地油气管道的电磁影响日益凸显,需采取有效措施予以抑制。研究基于麦克斯韦方程组建立Taylor场线耦合模型,计算了稳定运行状态下输电线路在并行油气管道上所产生的交流电磁干扰;分析了线路塔高、线路与管道水平距离、线路电压等级、管线并行长度、土壤电阻率等因素对管道感应电压大小的影响。可为输电工程及石油工程的管线敷设的结构设计提供参考。
Along with the development of energy public channels in our country, the electromagnetic interference generated by the AC overhead transmission lines becomes a growing matter of concern, so some measures must be taken to prevent it. In this paper, the field - line coupling Taylor model based on the MaxwelFs equations is used for the calculation and research of the electromagnetic interference on paralleled oil pipelines when the transmission lines running stably. In addition, the paper focuses on the influence factors such as the height of tower, the hori-zontal distance between the overhead lines and the pipelines, the voltage level of the transmission lines, the parallel length and the soil resistivity. The results of the study can provide advice for the construction projects of the power transmission lines and the petroleum pipelines.
