Wind turbine torque-speed control

The present subject matter relates to methods and systems for operating a wind turbine 600 that, in some embodiments may include a gearbox. The wind turbine 600 is provided with a blade 622 having an adjustable pitch angle and the tip speed ratio (TSR) of the blade is monitored. In operation, the me...

Zusammenfassung:	The present subject matter relates to methods and systems for operating a wind turbine 600 that, in some embodiments may include a gearbox. The wind turbine 600 is provided with a blade 622 having an adjustable pitch angle and the tip speed ratio (TSR) of the blade is monitored. In operation, the method and system is configured to increase the pitch angle of the blade 622 concurrently with an increase in TSR to maintain turbine operation within an identified high power coefficient (Cp) operational region for the blade. TSR may be monitored by monitoring one of the velocity of the tip of the blade 622, wind speed, the rotational speed of the blade 622, or the rotational speed of a component within the gearbox.
