LLAMO LABORI, Hector Silvio. Equivalent parameters of phase and sequence of until eight transmission lines connected in cascada. Energética [online]. 2017, vol.38, n.1, pp. 35-41. ISSN 1815-5901.

In the National Electro Energetic System (NES) there is electric energy transportation lines connected in series that possess trams with different structures, conductors, arrows, ground resistivity etc. Its representation in the programs that calculate load flow, short circuit and stability problems make necessary to define so many additional fictitious nodes like the number of lines connected in cascade less one making difficult the work with these programs and increasing, the number of nodes of the electric network analyzed.In these work are presented the characteristics and the results of an algorithm that model the three phase electric energy transportation lines of any configuration and circuits numbers in phase quantity by mean of its Global Matrix Generalized Constants (GMGC), from it, the impedance (Z) and admittance (Y) matrices and finally, the zero and positive sequence parameters equivalents to N different lines connected in cascade. Key words: transmission lines, cascade, cuadripolos, matrix generalized constants

Keywords : transmission lines; cascade; cuadripolos; matrix generalized constants.
