Improvement of Power System Stability Using FACTS Device

This paper describes the impact of the Flexible AC Transmission System (FACTS) controller, namely Thyristor Controlled Series Capacitor (TCSC), on the transient stability of power transmission. For demonstration of the impact of TCSC on transient stability of a power system, a model of the Slovak power system was used. The devices with a suitable controller can also be used for many other purposes than those for which they were designed
