“…Energies 2021, 14, 8536 2 of 13 There are many reports on the electromagnetic interference (EM) of the induced voltage using the Electromagnetic Transient Program (EMTP) [14][15][16][17]. A practical calculation method using EMTP is presented in [14], which assumes multi-conductor power lines with a variety of tower types (complex approximation layouts), and multilayered soil models are parallel to a nearby pipeline. Heo et al [15] analyzed the induced voltage generated by overhead transmission lines under normal cases using the line and cable constant (LCC) module.…”

Analysis of Induced Voltage on Pipeline Located Close to Parallel Distribution System

Gas and oil pipelines are widely used to supply customers. They are often laid in parallel with high voltage power lines, sharing right of way. When the pipeline is located near overhead high-voltage power, corrosion caused by induced voltages from AC power lines can occur in utility pipelines. Therefore, the calculation of induced voltage is always required for both interference and maintenance workers as well as pipeline facility safety. For parallel distribution lines, the calculation method for the induced voltage is not suitable due to the excessive error caused by using the screening factors of the neutral current. For a more practical analysis of the induced voltage, a new analysis is needed using the actual neutral current and which also considers the overhead ground conductor and the neutral conductor. This paper analyzed the induced voltage from a parallel distribution system using Carson’s formula and vector analysis. Simulation analysis results are verified by separate Electromagnetic Transient Program (EMTP) simulation.

“…Previous research on induced voltage is mainly focused on overhead transmission lines [8][9][10][11][12][13][14][15][16]. The induced voltage on the pipeline is critical because the unbalanced current flow in the distribution system can increase the induced voltage on the pipeline.…”
