Abstract: Aiming at solving the problems of maximum power point tracking(MPPT) control of switched reluctance generator(SRG) wind generation system in laboratory, research on output characteristics of wind turbine and its imitation schemes, operation principle of SRG and its control methods were carried out, and MPPT control strategies of wind power generation system were introduced. A MPPT control strategy based on speed feedback of SRG generation system was proposed. Meanwhile, wind turbine was imitated by DC motor using torque control. Both the wind turbine imitation system and the MPPT control were tested under variable wind conditions. The results indicate that the DC motor can imitates the wind turbine effectively and the MPPT control method can achieve maximum wind power tracking accurately.

Key words: switched reluctance generator(SRG); wind power generation system; imitation of wind turbine; maximum power point tracking(MPPT).
