Abstract (EN): Voltage stability is concerned with the ability of a power system to maintain acceptable voltages at all busbars in the system under normal conditions, and after being subjected to a disturbance. A system enters a state of voltage instability when a disturbance causes a progressive and uncontrollable decline in voltage. In this paper it is studied and analysed the influence of the series capacitor compensation in the dynamic voltage stability assessment of an Electric Power System. It is used the BPA test power network considering different load models. A transmission line outage was simulated and different values of the series capacitor compensation were used to avoid voltage collapse. The automatic voltage regulators of the generating units and the turbine speed governors were modelled. The results were obtained using the software package EUROSTAG. Finally, some conclusions that provide a better understanding of the mechanism of the voltage collapse phenomenon that highlight the importance of the dynamic series compensation are pointed out.
