In recent years the Doubly-Fed Induction Generator (DFIG) based wind turbine system has gained a lot of popularity due to its various advantages, but it has certain demerits also. The sudden tripping of these generators because of the low voltage during fault conditions, results in poor grid stability. One of the most reliable solutions to this problem is the use of Flexible AC Transmission System (FACTS) devices. They ensure the uninterrupted operation of DFIG system and thus maintain the stability of the system. This paper presents the application of UPFC (Unified Power Flow Controller) and HPFC (Hybrid Power Flow Controller) in the DFIG based wind turbine system in order to provide the dynamic reactive power support at the point of common coupling amid three-phase fault condition. A comparison between the performances of the two devices has also been discussed. The simulation has been done in MATLAB/Simulink platform.
