Abstract: For smooth operation of the power system regardless of the various wind speed and system ground faults, the full rated inverter is applied in wind generator. This inverter has double loop control on both grid side and generator side. It is note that the voltage closed-loop control as an innovative use is attributed for grid side control. The pitch angle controller is designed to meet both various wind and system faults according to the input signal. Simulations for evaluated the performance are conducted and the results verify that the proposed control strategy with the high efficiency satisfies requirements both WT control and the quality of the power grid.

Key words: full rated inverter, wind generator, various wind, pitch angle
