Title:
WIND TURBINE GENERATOR AND WIND POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2007051562
Kind Code:
A
Abstract:

To provide a wind turbine generator which has a simple structure, efficiently generates power, and can be installed in confined areas without restrictions in the installation place.

The wind turbine generator 1 comprises a wind-receiving vane 10, and piezoelectric plates 11a/11b. The wind-receiving vane 10 has a structure wherein a rectangular plate member having lengths of opposing short-sides equal to each other, and the length of at least five times the length of the short sides is breadthwise folded into two at a specified angle θ. The piezoelectric plates 11a/11b serve as a power-generation part which generates power by vibration of the wind-receiving vane 10. On receiving wind force, the wind-receiving vane 10 causes torsional vibration to develop deflection in the piezoelectric plates 11a/11b, and generates power.
