Abstract
AbstractThis paper has proposed a methodology to obtain a frequency dependent distributed‐parameter model for a buried bare conductor employing a time‐domain fitting from measured transient voltages and injected currents. The transient characteristic impedance and propagation function are expressed by a rational function in a z‐plane and a genetic algorithm (GA) has been used as an optimization tool. Frequency dependence of the per unit line parameters (RLGC) is derived from the obtained propagation parameters. Simulation results by the proposed model agree well with that from the measured results. © 2006 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
