Abstract
A wind power generation system including a power generation unit having an elastically deformable base material in a shape of a longitudinal flat plate and a piezoelectric element disposed on the base material, and which generates electricity as the power generation unit is vibrated; the piezoelectric element is repeatedly bent and deformed by the vibration and stacked on the base material, the wind power generation system being configured to include a tension adjusting device that, when a wind speed is increased, moves the movable member to increase a tensile force that pulls the power generation unit in the longitudinal direction, and the tension adjusting device being a lift generating member that is formed integrally with the movable member so as to be extended and to have wing shape to both sides of the movable member and that moves the movable member based on lift generated according to the wind speed.
