PROBLEM TO BE SOLVED: To provide prevention means of flow velocity reduction of flow processed by natural flow flowing outside, in a power generation device that enhances the velocity of flowing water to make processed flow and performs power generation with the processed flow.SOLUTION: A power generation device generates processed flow 48 with a flow velocity several times or several ten times higher than a flow velocity of processed flow 47 flowing in power generation flow passages 1-A, 1-B used for power generation; makes the processed flow 47 used for power generation acted in an extracted manner by synthesizing the processed flow 48 and the processed flow 47 used for power generation inside an automatic flow velocity amplification device; and makes the flow velocity of the processed flow in the power generation flow passages into a velocity with a design value. |
