A transmission line model is developed directly in the time domain based on the Bergeron's method. The inclusion of the frequency effect in the longitudinal parameters is performed in the time domain through the approximation of the Z(ω)by a rational function using vector fitting. The line losses are represented with a variable impedance as a function of frequency, modeled by discrete elements of electrical circuits obtained through the poles and zeros of the adjusted Z(ω) curve. Thus, the frequency effect can be included in the Bergeron's model directly in the time domain. The proposed model in this Master's thesis is validated with the results obtained from the prestigious Universal Line Model and with the line's model that takes into account the frequency effect through state equations
