Abstract

The behavior of electric power transient signal, in the high-voltage (HV) cables, is a significant problematic of real-world issues to the utility. Modeling this behavior with appropriate software is attractive attitude for most researchers, particularly in case of matching the calculated results with the real behavior. This paper introduces modeling and analysis of behavior of transient signal getting from treated and un-loaded underground cables via PSCAD simulating. A valuation of suitability of Bergeron and frequency dependent (FD) model (FD-mode model and FD-phase model) during transient within transmission cables is given. The fault transient signal and switching transient signal on the cable system are simulated and then presented. Through cable modeling, system parameters should be modeled in an accurate mode, like main core-conductor, main insulations, semiconductors, and cable sheaths. The transient signal sources are applied to 132kV underground XLPE cable system to examine the effects of cable parameters and external factors due to the transient signal behavior. Effect of each main component studied and its effect on the transient signal analyzed.
