Zusammenfassung:	Provided are a control method and apparatus for load reduction of a wind turbine. The control method for load reduction includes: determining a representative blade root load value of a wind turbine; determining an additional pitch rate value based on the representative blade root load value; determining a pitch rate control value based on a given pitch rate value and the additional pitch rate value; and applying the pitch rate control value to each blade of the wind turbine, to control each blade of the wind turbine to perform a pitch action.
