Enhancement of Passive Sliding Mode Control Model for LVRT Capability in DFIG Based Wind Turbines
ABSTRACT Doubly fed induction generator (DFIG) is vulnerable to transient stability situations occurring on the grid side. First of all, with the models to be developed in the wind turbines, LVRT capability must be provided depending on the grid code requirement for various problems that may occur, such as overcurrent, voltage, and uncertainty in ...

LVRT Research of PMSG Wind Turbine Using Feedback Linearization
Analyzing the wind turbine with a direct-driven PMSG, this paper proposes a low voltage ride through scheme of PMSG wind power systems based on feedback linearization. The DC-Link voltage is controlled by the generator-side converter rather than the grid-side converter.
