Abstract :
Stabilizing control for power system stability has been applied to generators equipped with excitation controller and speed governor. Recently, power electronics-based control devices have been the focus of research and development for the improvement of dynamic stability. Power electronics control devices are utilized for control of the power flow on a transmission line or the reactive power in a power system. In this paper it will be presented a thyristor controlled series compensation strategy to improve the dynamic voltage stability of an electric power system. In this study it was simulated a significant load demand disturbance in a test power network. The automatic voltage regulator of the generating units, the under load tap changer and loads were taken into account. The simulation results were obtained using EUROSTAG software package.
