Apport de l'UPFC à l'amélioration de la stabilité transitoire des réseaux électriques

Abstract : The main prupose of this research is the modeling, the identification of the references and control of UPFC d'UPFC (Unified Power Flow Controller), in order to improve the transient stability of generator connected to an infinite bus. In order to analyse the influence of the UPFC on the network, the mathematical model of a UPFC connected to an infinite bus is presented. Various methods of identification of references ( instantaneous power, decoupled Watt-Var ) and various regulators ( P, PI, IP, RST ) for the shunt part and also series part of the UPFC are studied in the steady state operation. Different methods for identification of the series part like " optimal parameters ", " injection model ", and " state variables " in order to improve the stability of the system, are studied. Finally, a new method for identification based on " state variables " using the local parameters of the system is proposed and tested through the simulations.
