Análisis de Sensibilidad Computacional de la Respuesta en Frecuencia de la Impedancia de Torres de Transmisión

Abstract

The frequency response of the impedance seen from the top of two towers by the Hybrid Electromagnetic Model is determined. The model considers variations in the geometry of the towers, geometry of grounding system, and soil resistivity. The evaluation of electromagnetic transients in transmission lines involves different components being towers the elements that can further influence the magnitude and wave shape of the generated transient. The frequency response shows a predominantly inductive behavior. For that reason, frequency response is fitted to impedance expressions of a series-inductivecapacitive circuit in terms of Laplace transform, obtaining inductance values in ranges similar to values reported in the literature.
