grid codes wind turbinesmust have low voltage ride-through (LVRT) capability. In this paper a new crowbar systemis proposed so that along with the control system it protects the IMC from large fault currents and supports the grid voltage dips during...

of the bulky electrolytic capacitor. According to the recent grid

codes it is required that the wind turbines remain connected to the grid during the grid

faults and the following voltage dips. This feature is called Low Voltage Ride-Through
