Analyzing The Transmission Line Parameters In Frequency Domain

The objective of this paper is to analyze the influence that the ground wires and soil and skin effects have on the R and L transmission line parameters. Initially a theoretical analysis of the influence which the ground wires have on the R and L parameters is presented. Some results obtained of a hypothetical line with frequency constant parameters and of a line with variable parameters are presented. The individual influence of the skin and ground effects on the R and L parameters is analyzed.2WINTER MEETING878883Tavares, M.C., Modelo de linha de Transmissão Polifãsico Utilizando Quase Modos (1998), Tese de Doutarado, Campinas, São Paulo, BrazilChipman, R.A., Teoria e Problemas de Linhas de Transmissão (1976), Editora Mc Graw-Hill do Brasil LTDADeri, A., Tevan, G., Semlyen, A., Castanheira, A., The complex ground return plane a simplified model for homogeneous and multi-layer earth return (1981) IEEE Trans. on Power Apparatus and Systems, PAS-100 (8). , AgostoSaad, O., Gaba, G., Giroux, M., A closed-form approximation for ground return impedance of underground cables (1981) IEEE Trans. on Power Delivery, 11 (3). , JulhoD'Amore, M., Sarto, M.S., A new formulation of lossy ground return parameters for transient analysis of multiconductor dissipative lines (1997) IEEE Trans. on Power Delivery, 12 (1). , JaneiroRachid, F., Nucci, C.A., Ianoz, M., Transient analysis of multiconductor lines above a lossy ground (1999) IEEE Trans. on Power Delivery, 14 (1). , JaneiroFuchs, R.D., Transmissão de Energia Elétrica - Linhas Aéreas (1977), Livros Técnicos e Cientificos Editora S.AGustavsen, B., Semlyen, A., Combined phase and modal domain calculation of transmission line transients based on vector fitting IEEE Trans. on Power Delivery, 13 (2). , AbrilHayt W.H., Jr., Engineering electromagnetic (1981), Mcgraw-Hill, fourth editio
