Voltage stability has been a bottleneck to further development of wind power. However,the wind power systems based on the hydraulic drive system,due to its stability in the output and lightweight and flexibility, helps to address the bottleneck. Though modeling and taking into consideration of the work characteristics,this paper simulates and studies the stability of the output of the hydraulic drive wind turbine under various wind speeds. In addition,on the basis of considering the operating characteristics of the induction generator, the improved continuous flow algorithm is used to analyze the static voltage stability with wind power integrated with power grid.
