Influence combinée des UPFC et des PSS sur la stabilité transitoire des réseaux électriques

Abstract

The traditional methods of control of the networks that were the electromechanical devices could in the future prove too slow and insufficient to answer the disturbances of the electrical supply networks effectively. It will thus be necessary to supplement their action by implementing electronic devices of power having short, known response times under name FACTS (English acronym of: Flexible device Alternative Current Systems Transmission) with other controllers like the PSS (Power System Stabiliser) for the control of the electrical supply networks. This work, presents the combined influence of the one and most powerful of these devices, namely the UPFC and the power system stabiliser PSS in transient stability of the networks tests subjected to the various disturbances. A comparative study has been made between the influences of these two devices to improvement transient stability used software SIMULIK/MATLAB.
