Induction generator Wikipedia

An induction machine requires an externally supplied armature current Because the rotor field always lags behind the stator field the induction machine always consumes reactive power regardless of whether it is operating as a generator or a motor A source of excitation current for magnetizing flux reactive power for the stator is still required to induce rotor current
