Avaliação da margem de estabilidade estática de tensão considerando cenários de contingência em redes de transmissão

Abstract

This paper presentes a static voltage stability study, throught the evaluation of the margin of voltage stability for diferrent load models, with and without limits de reactive generation in the system, with and without the presence of contingencies in the power system,a study of the Available Capacity of Transmission was also analyzed, the results obtained by the program developed here were obtained using the decoupled Newton-Raphson numerical method, and validated with professional software ANAREDE, in both the input data was in the same format. The system studied was the system of 45 buses reduced South-Southeast Brazilian system.
