%X In the National Electro Energetic System (NES) there is transmission lines at 110 and 220 kV connected in cascade or inseries that posses trams with different structures, conductors, arrows, ground resistivity etc. Its representation in theprograms that calculate load flow, short circuit and stability problems, used in the Electric Load Dispatch (ELD) of theElectric Union, make necessary to define so many additional fictitious nodes like the number of lines connected in cascadeless one making difficult the work with these programs and increasing, unnecessarily, the number of nodes of the electricnetwork analyzed.In these work are presented the characteristics and the results of an algorithm that model the threephase electric energy transportation lines of any configuration and circuits numbers in phase quantity by mean of its MatrixGeneralized Constants (MGC) (A), (B) (C) and (D), with an order of three by the line circuits number and utilizes thecuadripolos property connected in cascade for obtaining the equivalent cuadripolo of ¡°N¡± cuadripolos connected incascade and, from it, the impedance (Z) and admittance (Y) matrices. From these matrices, using the SymmetricalComponents Transformation Equation (SCTE), are calculated the zero, positive and negative sequence parametersequivalents to ¡°N¡± different lines connected in cascade.
