Explain the difference between active stall control and passive stall control
What will be an ideal response?
Active stall control is used to control rotor speed by a mechanically moving the
blade pitch into and out of stall condition as necessary. Typically this is done with hydraulic controls.
Passive stall control uses the basic design of the turbine blades to create turbulence on the back of the blades in strong winds thus slow the turbine in high winds
