Estudo de estabilidade transitória de sistemas elétricos de potência utilizando o método passo-a-passo para cálculo da curva de oscilação da máquina síncrona.

Abstract

This work presents the development of an algorithm using the Step-by-Step Method in the GUIDE module of MATLAB software in order to study the stability of a power system constituted by a machine against an infinite bus. Besides the algorithm, this work also aims to study the transient stability of the system by analyzing the behavior of the oscillation curve of the synchronous machine soon after a disturbance. For this, an introduction is made first to the study of stability in electric power systems, presenting the problems and premises and classifying within this area the different types of phenomena that are considered. Next, the theoretical part of the study is presented, where fundamental concepts and the mathematical basis are provided to understand the behavior of synchronous machines within this area of study. Finally, the algorithm developed, the obtained results, comparisons with other validated results and the conclusions of this work are presented.
