        Real-time estimation of transmission line impedance based on modal analysis theory 

        Universidade Estadual Paulista (UNESP); Universidade Estadual de Campinas (UNICAMP) (2011-12-09)
        The objective of this paper is to show a methodology to estimate the longitudinal parameters of transmission lines. The method is based on the modal analysis theory and developed from the currents and voltages measured at ...

        Real-time estimation of transmission line impedance based on modal analysis theory 

        Asti, G. A.; Kurokawa, S.; Costa, E. C M; Pissolato, J. (2014)

        A First approach on the new transmission system in northern Brazil 

        Universidade Estadual de Campinas (UNICAMP); Universidade Estadual Paulista (UNESP) (2011-12-01)
        This article shows an analysis of the electrical parameters of a three-phase transmission line section using a relatively new design for steel towers characterized by 280 meters high. These main features, the height of the ...

        Sensitivity analysis for overload-relief in transmission lines using an implicitly coupled method (CRIC) 

        Universidade Estadual Paulista (UNESP) (2006-12-01)
        The restructuring of energy markets to provide free access to the networks and the consequent increase of the number of power transactions has been causing congestions in transmission systems. As consequence, the networks ...

        Behavior of overhead transmission line parameters on the presence of ground-wires 

        Universidade Estadual Paulista (UNESP); Universidade Estadual de Campinas (UNICAMP); Universidade Federal do Rio de Janeiro (UFRJ) (Institute of Electrical and Electronics Engineers (IEEE), 2005-04-01)
        Initially this paper shows the ground wire reduction process for generic multiphase transmission lines and after, the ground wire reduction process for a specilic 440-kV three-phase overhead transmission line. Following ...

        Corona effect in frequency dependent transmission line models 

        Universidade Estadual de Campinas (UNICAMP); Universidade Estadual Paulista (UNESP) (2008-12-01)
        The inclusion of the corona effect in a frequency dependent transmission line model is proposed in this paper. The transmission line is represented through a cascade of π circuits and the frequency dependence of the ...

        Identification of transmission line parameters from temporal measurements of currents and voltages in their terminals: Influence oh the length line 

        Universidade Estadual Paulista (UNESP); Universidade Estadual de Campinas (UNICAMP) (2012-12-11)
        The objective of this paper is to show a methodology to estimate transmission line parameters. The method is applied in a single-phase transmission line using the method of least squares. In this method the longitudinal ...

        Sensitivity analysis for overload-relief in transmission lines using an implicitly coupled method (CRIC) 

        Hoji, E. S.; Padilha-Feltrin, A. (2014)

        An alternative modal representation of a symmetrical nontransposed three-phase transmission line 

        Universidade Estadual Paulista (UNESP); Universidade Estadual de Campinas (UNICAMP) (Institute of Electrical and Electronics Engineers (IEEE), 2007-02-01)
        The objective of this letter is to propose an alternative modal representation of a nontransposed three-phase transmission line with a vertical symmetry plane by using two transformation matrices. Initially, Clarke's matrix ...

        Representation of transmission lines in modal domain using analytical transformation matrices 

        Universidade Estadual Paulista (UNESP); Universidade Estadual de Campinas (UNICAMP) (2011-05-31)
        The phases of a transmission line are tightly coupled due to mutual impedances and admittances of the line. One way to accomplish the calculations of currents and voltages in multi-phase lines consists in representing them ...
