Title:
WIND POWER GENERATION DEVICE AND METHOD OF CHANGING SYNCHRONOUS SPEED
Document Type and Number:
Japanese Patent JP2003042054
Kind Code:
A
Abstract:

To inhibit reduction of the generation efficiency in changing the synchronous speed.

The wind power generation device generates power by changing the number of poles of a generator according to the wind velocity. The synchronous speed is changed by utilizing the mechanical braking torque.
