RESUMO

In this work, the influence of two FACTS devices, the Tiristor Controlled Series Compensator (TCSC) and the Static VAr Compensator (SVC), on power systems low frequency electromechanical oscillations damping, is analyzed by modal analysis, including critical eigenvalues identification and bifurcation analysis. A Power Sensitivity Model is used to represent a single machine infrnite bus system. The results obtained show that both devices are effective in damping rotor oscilIations, emphasizing that the Tiristor ControIled Series Compensator provides a better effectiveness than the Static VAr Compensator in keeping system angular stability.
