The fault ride-through and grid support capabilities of the doubly fed induction generator (DFIG) wind turbines mainly address the design of DFIG wind turbine control with emphasis on power converters protection and voltage control issues. This paper presents the development of a protection and voltage control strategy for DFIG wind turbines, which enhances the fault ride-through capability of DFIG wind turbines and their ability to provide voltage control during grid faults. The performance of the proposed protection and voltage control strategy is assessed through the simulations of a 2MW DFIG wind farm. To protect the rotor side converter, a crowbar at the rotor is switched on. The performance of an active crowbar during voltage dips is investigated for several parameter sets of machine, resistor and control.
