In order to improve the performance of variable speed constant frequency power generation system,this paper adopted the method of combining the theory of excitation control optimization and simulation,and established model for doubly-fed wind generator system.Through the theory of the maximum power point tracking（MPPT） algorithm and optimal algorithms,this paper proposed a strategy which does not depend on wind speed measurement to achieve doubly-fed wind power generation system that has a maximum power point tracking（MPPT） control.Matlab software was used to establish a simulation model of variable-speed constant-frequency doubly-fed wind power generation and analyze by numerical simulation.The result verifies the accuracy of this research method.For the promotion of green energy technologies,energy conservation has important theoretical and practical significance.
