| Abstract: | The control strategy for high speed wind turbine with permanent magnet synchronous generator （H-PMSG） was investigated to enhance its capability of low voltage ride through（LVRT）.A H-PMSG model comprising of a host AC power grid with two back-to-back PWM voltage source converters was established in the software matlab/simulink. It has simulated two operation conditions generator and converter when grid voltage dip by 30%（0.6 seconds） ,60%（2 seconds）.The simulation indicated that H-PMSG power tracked well. It could provide reactive power support when the grid voltage dip. The H-PMSG had a strong low-voltage penetration capability. |
