Abstract
A wind turbine pitch control system is disclosed that provides a pulsed torque to the blade pitch actuator if continuous torque fails to adjust the blade pitch angle to a commanded pitch angle. This invention provides a cost-effective way to increase peak torque capability for existing wind turbines that have problems, under certain operating conditions, moving blades per the control command.
