“…The accuracy of parameter estimation method introduced in [38] considerably lessens for loads with AP above 10 MVA especially with PF values close to unitary. The present methodology shows better accuracy and more immunity to noise in case of loads with high AP.…”

“…− ∂ 2 i ∂x 2 = Y Z I (19) where Clarke transformation -which is more commonly used in EMTP-like programs among modal transformation methods-is chosen for decoupling in this paper, where One of the Clarke transformation advantages is that T −1 i = T t i , which makes calculation of modal quantities easier. Applying Clarke transformation to (18) and (19), the three-phase line is modeled into three single-phase lines and gives the modal voltages and currents. The proposed identification method accomplished, as described in Section II, and the positive and zero sequence characteristics impedances and resistances are determined.…”

“…However, obtaining synchronized measurements at two terminals of transmission line -sometimes miles away from each other-is not a proper practical solution and only a few parameters of admittance and impedance matrices could be accurately calculated [19], [20]. Although these techniques increase the exactitude of the results [21], [22], their requirement of communication links and synchronized sampling equipment (e.g.…”

“…Quizá uno de los limitantes en la práctica es el instrumento que permita obtener esta medición, se puede utilizar unidades de medición fasorial PMUs o registros de fallas obtenidos de los relés de protecciones de la línea [1], [5]. Si bien es cierto existen diversos métodos para la estimación de parámetros, se debe tener en cuenta que la efectividad de los mismos difiere dependiendo de las características del sistema eléctrico, la geometría de la línea y la dinámica del sistema, de todas formas, cada método de estimación es efectivo para un punto de operación específico del sistema eléctrico y típicamente son pocos los parámetros de las matrices de admitancia e impedancia que se pueden estimar con precisión [6], [7].…”
