Stall Regulation

The blades on a stall-regulatedWT cannot be pitched. To achieve control of power captured above rated wind speed, the blades are carefully designed so that they progressively stall starting at the blade root and moving out towards the tip as the wind speed increases further. Stall-regulated WTs will respond much more quickly to gusts than pitch-regulated WTs (where mechanic pitch adjustments take finite amounts of time to effect), improving the power quality output by the WT above rated wind speed.
