考虑定子频率变化的双馈感应发电机

This paper presents an adaptive repetitive control method for torque ripple suppression of the doubly fed induction generator (DFIG) system connected to a dc grid considering the stator frequency variation. Since the stator of DFIG is connected to the the diode bridge directly, the stator frequency should be controlled additionally. A novel frequency-locked loop (FLL) based on a second-order gener...
