Análisis de los sobre voltajes en sistemas de transmisión con discontinuidades determinadas por líneas aéreas, cables y subestaciones aisladas en SF6, usando ATP - EMTP: análisis de los sobre voltajes de frente lento (maniobra) en sistemas de transmisión con discontinuidades determinadas por líneas aéreas y cables aislados, usando ATP - EMTP.

Abstract

This curricular integration work is based on the analysis of slow front transient overvoltages in electrical power systems with discontinuities defined by overhead transmission lines and insulated cables to understand the problems that this entails and thus be able to find new ways to implement these short term settings. The analysis is carried out for different cases on a test system that was implemented in the ATP software, for which each of the parts of the network was modeled in order to parameterize the different modules that were used. Study cases were selected in order to evaluate the behavior of each of the characteristics of interest of the insulated cables, in order to better understand how these can influence slow-front transient overvoltages and anticipate mitigation methods. previously. The results of each test were presented individually, comparing the overvoltage values obtained with respect to those of the base case, evaluating the behavior of the overvoltages, giving a meaning based on cable theory and identifying the worst situations in which they can occur. these phenomena in actual practice.
