Abstract
The methods of vector transform and PI controller are used in no-load cutting-in control scheme of the system of doubly fed induction wind power generator, but the control methods depend on the parameters of electronic machine strongly. For raising the steady of wind power generating system, this paper designs a fuzzy PI controller which with strong robustness and fast dynamic response of fuzzy controller and better steady precision of PI controller. The result of simulation indicates that the fuzzy PI controller not only shorts the process of no-load cutting-in, but also has strong robustness and fast dynamic response, it is an ideal cutting-in control strategy.
