A novel transient rotor current control scheme of a doubly-fed induction generator equipped with superconducting magnetic energy storage for voltage and frequency support |
Overall scheme diagram of the proposed control strategy. Here, w r and w ref are real rotor speed and rotor speed references, respectively, θ s, θ r, and θ 1 are the stator, rotor and slip electrical angulars, respectively. w s and w r are stator and rotor angular speeds, respectively. |
