Control Strategy Study of DFIG with LVRT

2009 International Conference on Energy and Environment Technology, 2009
In recent years, the proportion of the wind power in the grid is increasing rapidly. When the grids faults results in voltage decline, the widespread tripping of wind generators could lead to transient instabilities and local or overall blackouts. So it is concerned that the wind turbines merge into the grid and the request of the low voltage ride ...

A Dynamic LVRT Solution for Doubly Fed Induction Generators

IEEE Transactions on Power Electronics, 2009
Doubly fed induction generators have become the most common type of wind turbine generators. However, this type of generator is susceptible to grid-side low voltage and short circuits due to existence of a power electronics converter on the rotor side.

DFIG's virtual resistance demagnetization for crowbar less LVRT

2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS), 2017
Due to the increased renewable power penetration level renewable power plants have to provide low-voltage ride-through (LVRT) capability with simultaneous dynamic voltage support, to ensure the grid stability during grid faults. Concerning doubly fed induction generator (DFIG) based wind energy conversion systems (WECS) large transient electromotive ...

Impact of ASD settings in its LVRT behaviour

SPEEDAM 2010, 2010
A common matter of concern in industrial installations is that adjustable-speed drives (ASD) trip due to voltage sags. ASD manufacturers are including more and more in these devices settings related to control strategies (e.g. allowable DC voltage levels, etc) in order to improve their Low Voltage Ride Through (LVRT).
