<p>An apparatus for generating electric power from wind energy includes a blade unit (5), a wind-collecting unit (6), and a control unit (8). The blade unit (5) includes an upright shaft (51) mounted rotatably on a base (4), and a plurality of blades (521) connected fixedly around the shaft (51) and driven by wind to rotate. A generator (9) is connected to the shaft (51) for converting rotational kinetic energy into electric power. The wind-collecting unit (6) includes upright plates (61) mounted pivotally on the base and disposed around the blades (521). The control unit (8) detects rotational speed of the shaft (51) and accordingly moves at least a portion of each upright plate (61) between first and second positions, where the amount of wind flowing toward the blades (521) is increased and reduced, respectively.</p> |
