Prоblem 3: (25 pоints) The pаrаmeters оf а DFIG are given below. The stator is connected to a three-phase grid at 650 V RMS (line-line) and 60 Hz. The rotor speed (mech) is 1080 RPM and the wind power captured is 0.75 MW. The stator reactive power is controlled to be zero. You may neglect all losses except the losses in the rotor resistance. The turns-ratio between the stator and rotor windings can be assumed to be 1:1. Assume grid voltage orientation where the d axis is aligned to the grid voltage space vector. Neglect stator resistance and stator leakage inductance. Rotor resistance, Rr: 0.003
