Analysis of Traveling Waves Propagation Characteristics Considering Different Transmission Line EMTP Models
A Traveling Wave (TW) based propagation analysis of two different transmission line (TL) models available in Electromagnetic Transients Programs (EMTP) is presented in this paper, namely: Bergeron and JMarti models. Firstly, transients induced by a single-phase fault are analyzed assuming ideally transposed (IdT), transposed (T) and untransposed (UnT) TLs. Current signals are evaluated in order to verify differences between TWs propagation when each analyzed model is taken into account. Secondly, the impact of earth resistivity (ρe) has also been investigated. From the obtained results, it is concluded that relevant differences can show up in TWs propagation features due to the applied EMTP TL model, ρe values and also to the modeled transposition scheme, being the ground mode more affected from one case to another.
