| description | The invention discloses a wind turbine generator independent variable pitch control method and system based on load partition control. The method comprises the steps that the blade root load, the impeller azimuth angle and the generator rotating speed of each blade of a unit impeller under a rotating hub coordinate system are measured in real time; based on the deviation signal of the rotating speed of the generator, obtaining a unified variable pitch instruction of each blade; according to the measured blade root load and the impeller azimuth angle, an additional variable pitch instruction of each blade is obtained based on load partition control; according to the unified variable-pitch instruction and the additional variable-pitch instruction of each blade, obtaining a compensated independent variable-pitch instruction of each blade; and independently controlling the variable pitch operation of each blade based on the compensated independent variable pitch instruction. According to the method, partition con |
