Application of Dynamic Voltage Restorer for Enhancing low voltage Ride-through capability of Doubly Fed Induction Generator

Abstract

Doubly Fed Induction Generator (DFIG) based wind Energy System are very sensitive to grid disturbance such as Symmetrical voltage sag. In this paper the authors propose a new method for application of Dynamic Voltage Restorer for enhancing the low voltage ride through capability of wind turbine driven Doubly Fed Induction Generator.
