Avaliação de operação em sincronismo de uma central geradora hidrelétrica e rede elétrica

Abstract

This work presents a study on the transient stability of a central hydroelectric generating subject to disturbances in the system. In this ways, there will be a study on the mathematical modeling of synchronous machine, transmission network, of excitation systems, speed governor, turbine and load. For conducting this analysis was also required a study of the methods of transiente stability, covering some numerical integration methods and the criterion of equal areas. It shows a brief theory of relieving the load, which can be considered as an alternative for the occurence of some disorders to be treated. For such, it will be performed simulations in MATLAB software, with the use of Euler methods and Euler modified to demonstrate the system’s response after the disturbances.
