“…First, as with any other aspect of power system modeling, transmission line modeling needs to adapt to the changing conditions of the modern grid. One aspect that has attracted attention is the fact that analyses of power grids with integration of distributed generation (DG) require, in many cases, of EMT models even when performing studies that would traditionally use phasor models [7]. This is due to the fast dynamics of modern power electronic components used for DG integration, which extend to a much wider frequency range above the nominal frequency [8].…”

<p>This paper introduces a wideband parameter estimation approach for untransposed three-phase overhead transmission lines. The proposed method involves an accurate reconstruction of the 2-port nodal model of the line over a wide frequency band from terminal measurements obtained for a set of tests. The minimum norm least-squares method is applied for the solution of the overdetermined mathematical system resulting from these tests. The reconstructed model is further solved for the series impedance and shunt admittance matrices without the need for modal decupling techniques. Terminal voltage and current measurements used as inputs are simulated using software ATP for several tests that consider different tower configurations. The estimated parameters are compared with those computed analytically, with very close results when compared with analytical parameter calculation considering full frequency dependence. </p>
