Parameter estimation of arbitrary-shape electrical cables through an image processing technique

Original Paper


A novel numerical estimation of power electrical parameters with arbitrary-shape cross sections using a here implemented image processing technique is presented in this paper. This begins with the acquisition of the photograph of the cross section of the cable. Then, the photograph is preprocessed with filters for removal of artifacts and to correct anomaly conditions during the image acquisition. The estimated resistance and inductance loops obtained in this paper are accurate with respect to the ones calculated with the coaxial transmission line theory for concentric cables and with the finite element method for non-concentric three-phase and sector-shaped cables. To test the accuracy of the cable parameters the voltage transient step-response at the remote-end of different cable geometries is simulated in the time domain and synthesized in the frequency domain. Finally, the obtained transient step-responses are validated with actual measurements from scaled prototype experiments developed in the laboratory.
