一种仅需定子电感的并网双馈感应发电机转子电流滑差角估计器

This paper proposes, for variable-speed, grid-connected doubly fed induction generator (DFIG), a slip angle estimator, which is based on rotor current estimation in the synchronous reference frame. This estimator eliminates the need for a speed sensor or a rotor position encoder. The proposed estimator eliminates the need for an integrator to estimate the stator flux and, compared with other model...
