摘要：
This paper presents a novel control technique for fault ride through of a DFIG-based wind energy system. Both unbalanced faults and balanced faults are considered. For unbalanced faults, a close to 120 Hz component will be present in the rotor currents. For balanced faults, the rotor currents will experience a surge. The control technique presented in this paper is effective in mitigating the high frequency harmonic components and reducing the surge in the rotor currents. The novelty of the control technique is its simplicity and effectiveness: (i) only one reference transformation (abc/alpha beta) is required and (ii) harmonic filters are not required. Simulations performed in Matlab/Simulink are presented to illustrate the effectiveness of the proposed control strategy.
