Abstract
Doubly fed induction generator have become the most common type of wind turbine generators. These wind plants are required to have grid ride through capabilities. [1] 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. When a short circuit or voltage sag happens on the grid side, the rotor current of the generator tends to rise, which could cause damage to the rotor converter. According to the grid codes these plant are required to remain connected to the grid in the event of voltage dip at the high side of the wind plant step of transformer also they should contribute to the power system by feeding the active and reactive power safely, necessitated by stability concern. But it is difficult to satisfy for wind plants using DFIG system since the DFIG stator is directly connected to the grid and the rotor is connected through RSC, hence complete DFIG system is very much sensitive to grid disturbances. To enhance LVRT capacity a feed forward current control scheme is presented for rotor side converter of DFIG.
