| Abstract: | According to the performance analysis of the mathematical model of the three-phase grid-connected inverter(GCI) of directly-driven wind turbine with permanent magnet synchronous generator(D-PMSG) under unbalanced grid conditions,a dual current-loop control strateg(DCC) which oriented on positive and negative voltage and current respectively was proposed to inhibit the DC voltage fluctuation and complete the wind generator un-off-line operation on grid faults.A 1.5MW D-PMSG with back-to-back IGBT frequency c... |
