Prоblem 2: (25 pоints) The pаrаmeters оf а doubly fed induction generator are given below. The stator is connected to a three-phase grid at 650 V RMS (line-line) and 60 Hz. Stator resistance: Rs = 0 (neglected for ease of calculation) Rotor resistance: Rr = 0.004 Ω Stator leakage inductance: Lls = 0.1 mH Rotor leakage inductance: Llr = 0.1 mH Magnetizing inductance: Lm = 1.5 mH Number of poles: 6 Stator-rotor turns ratio: 1:1 It is given that the system operates at a slip s = -0.1 and the stator delivers 1 MW to the grid at unity power factor. Draw the per-phase equivalent circuit corresponding to the given operating condition and parameters. Calculate the rotor speed, ωr. Calculate the following four phasor quantities at the given operating condition: Is (stator current), Im (magnetizing current), Ir' (rotor current), and Vr' (RSC voltage). Calculate the active power and reactive power processed by the rotor side converter.
