Análise de estabilidade transitória em sistemas elétricos de potência.

Abstract

Ideally, the loads should be constantly fed with voltage and frequency so as to satisfy the demands of the consumers. For this the study of voltage stability is indispensable. In this context, this work approaches a methodology to present and determine solutions for the analysis of the transient stability in electrical power systems. In order to evaluate the performance of the transient and mechanical measurements, a reduced power system model was used, consisting of an infinite rod system connected to the transmission line and to the induction generator. In addition, Matlabforam software has implemented solutions to the problem both in the use of numerical methods of differential equations (Euler, Runge-Kuttae trapezoidal) and in the creation of an interactive graphical interface that shows the single-line diagram of the system and the input options of data user interest. To evaluate the dametodology performance of electromechanical transient and interface calculations, simulations were performed.
