To avoid the waste of resources and improve the stability of generating power of early wind turbines. Aiming at the immature technical level of early wind turbine generators(WTGs), this paper proposes an adaptive PI control strategy for WTGs with variable pitch considering tower load shedding. First, to improve the adaptability of the pitch PI controller to different capacity units, the rotational inertia deviation normalization is used to realize the rotational inertia deviation auto-tuning. Second, to enhance the nonlinear compensation of wind turbine blades, the pitch gain scheduling module is designed. Then, two feedback links, anti-windup and tracking mode, are added on the basis of PI controller to avoid the problems of integral saturation and speed control failure of PI controller. In addition, to reduce the impact of wind load on the tower of the wind turbine, active damping control is added before and after the tower to suppress the vibration before and after the tower.
