“…The above-presented EMTP-RV implementation and the parametric analysis consider perfect parallel exposure between HVPL and MP. However, in practice [20,35,36], there are frequent situations in which above or underground MPs present oblique exposures to the HVPL axis (see Figures 18 and 19) [8].…”

This chapter presents some analysis of the modeling techniques used to evaluate the effects of electromagnetic interference phenomena that could occur when metallic pipelines are placed close to high-voltage power lines. The electric and magnetic fields produced by overhead power lines could perturb the normal operation of the metallic pipelines through induced currents and voltages. These perturbations could be dangerous for both pipeline operating personnel (as electrical hazard) and pipeline structural integrity (due to accelerated electrochemical corrosion phenomena). The chapter depicts the electromagnetic coupling mechanisms behind the abovementioned interference phenomena and how the induced voltages could be evaluated. A parametric analysis is showcased to highlight the influence of various geometrical and electrical parameters.

“…The resulting currents and voltages can lead to several kinds of unwanted effect. Workers coming into contact with the pipeline are subjected to shock hazards [3]; the connected cathodic protection systems and the pipeline itself can be damaged through accelerated aging and corrosion [4,5], as well as through perforations of its coating layer [6,7]. Pipelines can also be harmed by other sources of interference; for example, in recent years a number of works have been devoted to the effects produced by high-voltage direct current (HVDC) systems [8,9], as well as traction systems [10] and geomagnetic events [11].…”

The functionality of buried metallic pipelines can be compromised by the electrical lines that share the same right-of-way. Given the considerable size of shared corridors, computer simulation is an important tool for performing risk assessment and mitigation design. In this work, we introduce an open-source computational framework for the analysis of electromagnetic interference on large earth-return structures. The developed framework is based on FLARE—an efficient finite element solver developed by the authors in MATLAB®. FLARE includes solvers for problems involving static electric and magnetic fields, and DC and time-harmonic AC currents. Quasi-magnetostatic transient problems can be studied through time-marching or—for linear problems—with an efficient inverse-Laplace approach. In this work, we succinctly describe the optimization of time-critical operations in FLARE, as well as the implementation of a transient solver with automatic time-stepping. We validate the numerical results obtained with FLARE via a comparison with the commercial software COMSOL Multiphysics®. We then use the validated time-marching analysis results to test the accuracy and efficiency of three numerical inverse-Laplace algorithms. The test problem considered is the assessment of the inductive coupling between a 500 kV transmission line and a metallic pipeline buried in the soil.
