<p>A vertical-shaft windmill and a wind power generation system. Particularly a vertical-shaft windmill, wherein a support frame body as a wind power dam is constructed, a large number of shaft arrangement parts are formed, and a plurality of vertically long blades having tilted parts formed at their upper and lower end parts are disposed, in multiple stages, on vertical main shafts at the shaft arrangement parts to increase a wind receiving ratio. Thus, the vertical- shaft windmill can be used as a wind power generator having a large wind receiving area and a large wind receiving force in a fixed installation area, requiring less installation cost, and generating a large total power generation amount for the fixed area.</p> |
