Numerical Modeling Assessment of Electromagnetic Interference Between Power Lines and Metallic Pipelines: A Case Study

The rapid change in human migration from rural areas towards the biggest metropolitan areas across the world implies a reorganization of the utility transport networks creating new common right-of-ways between high voltage power lines (HVPL) and metallic pipelines. In this paper, induced voltages from HVPL to metallic pipelines are calculated using different numerical approaches. The induced voltages along a metallic pipeline are computed using the wide-known circuit theory and electromagnetic field theory approaches embedded under ATP, EMTP-RV and XGSLab software packages, respectively. In order to accurately quantify the impact of different topologies on the induced voltages along the pipeline, the length of the parallel routing, as well as the separation distance, are varied during the computational domain. Moreover, the CIGRE WG 36.02 criteria regarding the equivalent parallel sections are applied when circuit theory is employed and verified using the adopted electromagnetic field method.
