Caracterização de pontos de equilíbrio e análise de estabilidade de ângulo do rotor para pequenas e grandes perturbações em sistemas elétricos de potência

Abstract

The main objective of this monograph is to characterize the equilibrium points of a synchronous generator and, in addition, to perform a stability analysis concerning the rotor angle, when the generator is submitted to small and large perturbations in the electric power system. The systems covered are composed of a synchronous generator connected to an infinite bus. The technical issues addressed refer to the analysis of the nonlinear dynamic systems that describe the power system. The theoretical basis, equations and modeling of this system are presented. Furthermore, the results of simulations of two systems with distinct topologies are presented, which are simulated using a computational algorithm for stability developed through the MATLAB software.
