An Analytical-Numerical Framework for Electromagnetic Fields, Harmonic Losses, and Ampacity Assessment of Underground Power Cables
Description
This dataset contains the computational files and numerical results associated with the study “An Analytical-Numerical Framework for Electromagnetic Fields, Harmonic Losses, and Ampacity Assessment of Underground Power Cables.” The Python-based framework combines analytical and finite-difference electromagnetic calculations, temperature-dependent conductor properties, frequency-dependent AC resistance, harmonic-loss evaluation, and a reduced thermal-resistance model for steady-state cable ampacity. Copper and aluminum conductors are evaluated under identical geometrical and thermal conditions, and the influence of burial depth, soil thermal resistivity, and ambient temperature is investigated. A controlled nonsinusoidal waveform represented by a truncated Fourier series is also used to assess harmonic losses and spectral convergence. The results include electric- and magnetic-field verification, conductor losses, Fourier-convergence data, material comparisons, parametric ampacity analyses, and comparison with a published 132-kV underground-cable FEM benchmark. The files are provided to support reproducibility and further comparative studies of underground power-cable performance.
