Based on the principle of switched reluctance wind generator and its power output characteristics, a direct rotational speed disturbance maximum wind tracking method is proposed. Through the relationship between power and speed changes, the method uses a variable step size climbing search algorithm to adjust the maximum output power of switched reluctance wind generator. Comparing with the direct power disturbance maximum wind tracking method, the method which proposed avoid the instability which caused by the slow reducing of output power, and still have a high algorithm rapidity. A simulation model of wind power system is established. The results of simulation indicate that the proposed method can quickly achieve maximum wind power tracking with good static and dynamic characteristics under the condition of stable wind speed and variable wind speed.
