Abstract
In wind power generation with complicated wind conditions, a reliable and high effective maximum power point tracking (MPPT) strategy is needed to fully make use of wind energy and improve generation efficiency.On the basis of studying traditional methods, this paper presents an improved strategy of variable step three-point comparison method with controllable parameters.When power value changes below the defined value, this strategy keeps the rotating speed of generator to suppress power oscillation, while in the vicinity of maximum power point it reduces the step size exponentially so as to ensure precision and stability of MPPT.Parameters of the controller are selected by empirical method and Hua Luogeng optimization method that can meet requirements of most occasions.This strategy doesn`t depend on wind speed measurement device and it has been verified to be provided with good control effect.关键词
