Estudo de estabilidade transitória em sistemas elétricos de potência utilizando o método trapezoidal implícito

Abstract

This monograph presents the development of an algorithm, through the MATLAB® software, which aims to verify the transient stability in electric power systems. For that, firstly, this study provides a theoretical basis on the subtypes of stability in electric power systems and the main elements that constitute them. Also it discourses about the methods used to solve the ordinary differential equations that describe the behavior of synchronous generators connected to the electric power systems and the importance of the stability analysis of them. After that, this study demonstrates from systems found in literacture the application of implicit trapezoidal method in the transient stability analysis. Then, through flow charts, it presents the algorithm developed, setting the characteristics of the tested systems, the features and the algorithm operation mode. Finally, it shows the results of all the performed tests and presents conclusion over each of them.
