More Information
Summary:A load reduction control method for a wind turbine generator, the load reduction control method comprising: determining a representative blade root load value of a wind turbine generator (10); determining an additional variable pitch rate value on the basis of the representative blade root load value; determining a variable pitch rate control value according to a variable pitch rate specified value and the additional variable pitch rate value; and simultaneously applying the variable pitch rate control value to blades (15) of the wind turbine generator so as to control the blades (15) of the wind turbine generator (10) to perform a variable pitch action. A device and system using the load reduction control method for a wind turbine generator are further provided. The load level of the whole machine can be greatly reduced in the case where there is little influence on the generating capacity.
