Commande D’un Systeme Flexible (upfc)pour L’amelioration Du Transit De Puissance D’un Reseau Electrique

Résumé: The demand for electricity continues to grow and the primary objective of power generation companies is to meet market growth and consumer demand by ensuring a normal and uninterrupted supply. Fast network control systems using the resources provided by power electronics and control microelectronics. These systems are referred to by the common acronym FACTS (Flexible Alternating Current Transmission System) and have proven their reliability for long distance transmission for decades. they or they Allows better control and management of the power flow of lines close to the limit Its warmth. Finally, they should be able to improve the stability of the network, regardless of major outages. In the network or eliminate the influence of parasitic oscillations, such as subsynchronous resonance. The Unified Power Flow Controller (UPFC) is a new power transmission controller. The UPFC provides full dynamic control of transmission parameters, voltage, line impedance and phase angle. This article presents a useful tool for electrical utility engineers to assess the application of the UPFC, its impact on their power system, and what the shunt and series ratings would be. This article gives sets of equations for a system including the UPFC and an equivalent two-bus power supply network. A digital method tested with Matlab has been successfully validated with an analog model. The Matlab code given in the article makes it possible to carry out rapid parametric studies for the application of the UPFC
