Abstract:
1. A wind power generation system, comprising: a vertical axis wind rotor; a transmission mechanism; and generator sets and a supporting tower, wherein the vertical axis wind rotor is mounted on the supporting tower and coupled to the multiple generator sets via the transmission mechanism, wherein components of said wind rotor include a drag type blade, a lift type blade, a rotation shaft and a partition board, the drag type blade being provided at the center portion adjacent to the rotation shaft of said vertical axis wind rotor, the lift type blade being provided on the outer edge of said vertical axis wind rotor in which an opening is provided between the drag type blade and the lift type blade, several drag type blades and lift type blades being arranged symmetrically around the rotation shaft, and several partition boards divide the integral wind rotor in the axial direction of rotation shaft into several layers of wind rotor units, and wherein several lift type blades are additionally provided on the outer side of said lift type blades in the radial direction of the rotation shaft of the wind rotor in which openings are provided between the lift type blades, the drag type blades and all the lift type blades being arranged symmetrically around the rotation shaft of the wind rotor, and the drag type blades and the innermost lift type blades being secured to the partition board while a rigid frame connection is adopted between the lift type blades.
