A theoretical analysis of the wind power generation system using a simulated windmill

The new constitution method of the wind power generation simulator considering output characteristics of the wind-mill is proposed. The rotational speed of the windmill changes by not only wind velocity but also condition of the load connected with the generator. Therefore, the technique which fed back the torque of the generator was verified for the estimation of the rotational speed in addition to wind velocity and characteristics of the windmill. Characteristics of the operation of the simulator resembled actual windmill, and the validity of the simulator was approximately confirmed. In addition, derivation technique of the maximum power point proposed in advance was applied to this equipment, and the operating characteristic was verified by the experiment. wind power generation, simulation of the windmill, deceleration factor, maximum power point tracking.
