英文摘要	According to the performance analysis of the mathematical model of the three-phase grid-connected inverter (GCI) and the fluctuation mechanism on DC voltage of directly-driven wind turbine with permanent magnet synchronous generator (D-PMSG) under unbalanced network voltage conditions, a dual current-loop control strategy (DCC) which oriented on positive and negative voltage and current respectively is proposed to inhibit the DC voltage fluctuation, meanwhile the notch filter is introduced to conventional control strategy of phase-locked loop, so as to complete the wind generator un-off-line operation on grid faults. A 1.5 MW D-PMSG with back-to-back IGBT frequency converter is simulated in the PSCAD/EMTDC environment, and simulation results show that the maximum wind energy tracking is achieved in this system and the proposed DCC strategy can prohibit the rise of DC voltage successfully and enhance the ride-through capability of D-PMSG wind generation system under unbalanced network voltage conditions.
