Due to the growing demand of electrical energy, modem electrical systems have faced a variety of operational problems. To solve some of these difficulties, emerges the FACTS concepts and technology. This uses advanced equipments, which provide new ways to control and optimise power transfer from different locations. Focusing on this strategy arises the Unified Power Flow Controller-UPFC, consisting of a ingenious combination of two other well established devices, the Advanced Static Var Compensator-ASVC and the Advanced Series Compensator-ASC. The result is a promising equipment to enhance FACTS applications. Considering this as quite a new product, it is found relevant to carry on investigations in order to achieve a better understanding of its physical principies and performance under system conditions associated to power systems ideal and non ideal conditions. This is the main target for this thesis, i.e, UPFC modelling and equipment/system behaviour under power quality problems. The power units as well as the control models are implemented into the SABER time domain simulator and many studies are performed in order to emphasize the individual and overall equipment parts (ASVC, ASC and UPFC) under the established system conditions.
