In order to find a balance between energy efficiency and reliability of wind power generation system, this paper presents a switch control strategy. This paper establishes a wind power system simulation model by controlling the electromagnetic torque in the Matlab/Simulink environment. The electromagnetic torque consists of three parts: the equivalent control quantity ueq, the changing high-frequency part uN and the additional low-frequency part uNf. The ueq can make the system close to the optimal operating point, and uN、uNf make the system operate stably around the optimal operating point. The simulation results show that: the actual speed can track the best speed very well, and the fluctuation range of the electromagnetic torque is very small. This switching control strategy can effectively improve the efficiency of wind power generation system and reduce fatigue load, and it solves the problem of imbalance between energy efficiency and reliability.
