Question by Amy: What is stalling in a wind turbine rotor?
pLEASE EXPLAIN THE PHENOMENON OF STALLING.
Best answer:
Answer by BrambleThere are two basic approaches used to control and protect a wind turbine: pitch-control and stall-control. In pitch-controlled turbines, an anemometer mounted atop the nacelle constantly checks the wind speed and sends signals to a pitch actuator, adjusting the angle of the blades to capture the energy from the wind most efficiently. On a stall-regulated wind turbine, the blades are locked in place and do not adjust during operation. Instead the blades are designed and shaped to increasingly “stall” the [...]
