Title:
WIND POWER GENERATOR
Document Type and Number:
Japanese Patent JP2005020920
Kind Code:
A
Abstract:

To provide a novel technique for smoothing the start-up of a windmill in a wind power generator which generates power by utilizing the rotation of the windmill generated by wind force.

Axial force is generated in the propeller type windmills 24, 26 by a wind, and is utilized in the wind power generator 10. Therefore, start-up torque required by the windmill for overcoming the rotation resistance in order to shift the windmill from a stop state to a rotation state, is controlled so as to be smaller than the start-up torque assumed in a strong wind state larger than a setting value, in a weak wind state that the wind force is less than the setting value. The control of the start-up torque is executed by changing an air gap between a rotor and a stator in generators 36, 38 with the axial force.
