Title: SAVONIUS WIND POWER GENERATION DEVICE AND CONTROL METHOD THEREFOR
Abstract:
[Problem] To provide a wind power generation device that is provided with multi-stage Savonius windmills in the front-and-rear direction, and that enables the windmills to rotate efficiently against wind from any direction and improves power generation efficiency. [Solution] Three wind power generation units 200A-200C each having two Savonius windmills 210 disposed side by side are arranged so as to form a substantially equilateral triangle. A narrow space S is provided between the windmills at the front stage with respect to a wind direction W1, wind power passing from the front to the rear is received by inner wind-receiving buckets 213 so that the windmill on one side rotates clockwise and the windmill on the other side rotates counterclockwise. At the middle stage, wind power passing from the front is received by outer wind-receiving buckets so that the windmill on one side rotates counterclockwise and the windmill on the other side rotates clockwise. At the rear stage, the wind power having passed through the space S at the front stage is received by inner wind-receiving buckets so that the windmill on one side rotates clockwise and the windmill on the other side rotates counterclockwise. Further, in a view from the front, each of the inner wind-receiving buckets at the middle stage partially overlaps the outer wind-receiving bucket on the same side at the front stage, and each of the outer wind-receiving buckets at the rear stage partially overlaps the inner wind-receiving bucket on the same side at the front stage.
