Abstract (EN): In this paper it is studied and analysed the influence of the selective load shedding in the dynamic voltage stability assessment of the BPA test power network. The outage of a 500 kV overhead transmission line was simulated. Different values of emergency load shedding were used to avoid voltage collapse. The automatic voltage regulators of the generating units and the turbine speed governors were modelled. Different load models were used and the under load tap changers were also taken into account. The simulation results were obtained using the commercial transient software package EUROSTAG, developed by Electricité de France and Tractebel Energy Engineering. Finally some conclusions that provide a better understanding of the voltage collapse phenomena are pointed out.
