Estudo de estabilidade transitória em sistemas elétricos de potência utilizando métodos energéticos

Abstract

This study contemplates the development of an algorithm for transient stability analysis using a direct method, Potential Energy Boundary Surface (PEBS). For such, in this study it was examined the theoretical basis of transient stability in order to comprehend its concepts and how it is analysed in electrical power systems, for one machine infinite bus systems (OMIBS) and multi machine systems. Necessary mathematical models were also portrayed, along with their practical application on transient stability analysis by the numerical method, Equal Area Criterion (EAC) and, later, PEBS. Lastly, critical clearing time results obtained through implementation and simulation of the PEBS algorithm in MATLAB® were compared to data from other academic works for equivalent power system configuration.
