VERTICAL WIND POWER GENERATION SYSTEM, VERTICAL HYDROPOWER GENERATION SYSTEM, AND CONTROL METHOD THEREFOR

摘要

[Problem] To provide a vertical wind power generation system which is adapted for a wide range of wind speeds from gentle wind to strong wind, and which has a high efficiency of conversion into rotational energy, and a control method therefor. In addition, to provide a vertical hydropower generation system which is adapted for various flow velocities or flow rates, and which has a high efficiency of conversion into rotational energy, and a control method therefor.[Solution] A vertical wind power generation system 15 is provided with: a vertical blade 1; a plurality of linear vanes 2 arranged in multiple concentric circles; arms 3; a shaft unit 4; an electric generator 5; a pole 6; a shaft unit holding portion 7; a relative angle 8; a rotating means 9; a rotation angle control device 10; a planar coordinate system 11; a reference angle 12; a blade rotation angle 13; a rotation angle table 14; the vertical wind power generation system 15; wind speeds 16; a wind speed detection means 17; a rotational speed detection means 18; a wind direction detection means 19; a rotation torque 20; a rotation limiting torque varying means 21; an electric generator controller (rotational speed control means) 22; a power controller 23; a coupling portion 24; and an attachment portion 27. A flow velocity distribution imparting device 52 concentrates flow velocities at a rotation angle having a high generation efficiency to significantly increase generation efficiency .
