Variable-speed variable-pitch wind generating set maximum power tracking control method based on optimal resisting moment tracking

The invention discloses a variable-speed variable-pitch wind generating set maximum power tracking control method based on drive system drive characteristic compensation control. According to the variable-speed variable-pitch wind generating set maximum power tracking control method based on drive system drive characteristic compensation control, a torque sensor is installed at the connection position between the low-speed end of a main shaft and a hub, detected resisting moment is fed back, optimal resisting moment closed-loop control is achieved, and the resisting moment at the connection position between the hub and a low-speed shaft of the main shaft can be effectively tracked to form an optimal resisting moment change curve. Compared with a traditional self-optimization control algorithm, the variable-speed variable-pitch wind generating set maximum power tracking control method based on drive system transmission characteristic compensation control effectively carries out compensation control on a nonideal drive characteristic of a drive system, effectively eliminates dynamic influence caused by randomness and nondeterminacy of the wind speed on the optimal resisting moment, successfully solves the problem that the traditional self-optimization control algorithm cannot easily carry out accurate tracking on optimal resisting moment tracking when carrying out maximum power tracking, and effectively improves the capacity of the maximum power tracking of a wind wheel.
