The number of wind installations has grown worldwide at unprecedented rates in new scenario. Widespread tripping of
wind generators following disturbances could lead to propagation of transient instabilities and could potentially cause local or system
wide blackouts. This has provoked many utilities to adopt low voltage ride-through (LVRT) for wind turbines. This paper presents the
LVRT characteristic, reviews the effect that voltage dips have on the operation of doubly fed Induction generator. This paper provides a
comparative study on the low voltage ride-through (LVRT) capacity of wind energy conversion systems (WECSs) under variable Speed
Induction Generator (DFIG), with FACTS (Flexible AC Transmission) devices like STATCOM (Static Synchronous Compensator).
