This paper expounds on the direct-driven PMSG wind power system control strategy, and analyses the stability conditions of the system. The direct-driven PMSG wind power system may generate the intense mechanical vibration, when wind speed changes dramatically. This paper proposes a new type of torque control strategy, which increases the system damping effectively, mitigates mechanical vibration of the system, and enhances the stability conditions of the system. The simulation results verify the reliability of the new torque control strategy.<\/p>\r\n","references":"[1]\tLi S, Haskew T, Swatloski R P, et al. \u201cOptimal and direct-current vector control of direct-driven PMSG wind turbines,\u201d Power Electronics, IEEE Transactions on, 2012, 27(5): 2325-2337.\r\n[2]\tYan J, Lin H, Feng Y, et al. \u201cImproved sliding mode model reference adaptive system speed observer for fuzzy control of direct-drive permanent magnet synchronous generator wind power generation system,\u201d IET Renewable Power Generation, 2013, 7(1): 28-35.\r\n[3]\tBianchi F D, Mantz R J, Christiansen C F. \u201cGain scheduling control of variable-speed wind energy conversion systems using quasi-LPV models,\u201d Control Engineering Practice,2005,13(2):247-225.\r\n[4]\tDe Battista H, Mantz R J, Christiansen C F. \u201cDynamical sliding mode power control of wind driven induction generators,\u201d IEEE Transactions on Energy Conversion,2000,15(4):415-457.\r\n[5]\tSimoes M G, Bose B K, Spiegel R J. \u201cFuzzy logic based intelligent control of a variable speed cage machine wind generation system,\u201d IEEE Transaction on Power Electronics,1997,12(1):87-95\r\n[6]\tShen Y, Li F, Wu D, et al. \u201cdSpace based direct-driven permanent magnet synchronous wind power system modeling and simulation,\u201d 2012 UKACC International Conference on.
