control system for a wind turbine, method for controlling rotor imbalance in a wind turbine and wind turbine

摘要

control system for a wind turbine, method for controlling rotor imbalance in a wind turbine and wind turbine. It is a control system for a wind turbine that includes a detection system configured to determine at least one of a rotor load, a wind shear, a wind speed, and a load shear imbalance. An adjustment system is configured to adjust an axis moment setpoint correction value based on at least one of the rotor load, wind shear, wind speed, and load unbalance. A compensation system is configured to compute an axis moment correction command based on the axis moment setpoint correction value issued from the adjustment system. an angle system is configured to adjust an angle of at least one wind turbine blade based on the axis moment setpoint correction command, or a yaw system is configured to adjust the yaw position of a rotor with based on the axis moment setpoint correction command.
