Technical FAQs 4

Why do wind turbines limit rotor speed?

The last region happens with high wind speed, and in this region, the turbine limits its rotor speed to protect its mechanical and electrical components. This work is focused on the second region of operation with the aim to optimize the wind energy extraction in this region through turbine’s rotor speed control.

How to control a variable speed wind turbine?

A torque control method was proposed in , to control a variable speed wind turbine. The study investigated the utilization of the rotor side and the generator side speed signal for the torque control. It was found that the generator side provides better stability than the other one.

Can wind turbine rotors be controlled under variable speed?

However, the random and highly fluctuating wind speed has showed several challenges for their control. Control-ling the wind turbine rotor under variable speed has become an active research topic in the recent years, as the wind industry started to adopt more advanced control techniques due to the deficiency of the classical control methods.

What is a pitch controlled wind turbine?

Pitch controlled WTs have an active control system which varies the pitch angle of the turbine blades to decrease torque and rotational speed in WTs. This type of control is usually employed in high wind speeds only where high rotational speeds and aerodynamic torques can damage the equipment.
