<P>PROBLEM TO BE SOLVED: To provide a wind turbine generator capable of starting power generation with a simple structure, even if wind power energy is small. <P>SOLUTION: Wind turbines 300, 350 having a plurality of vanes are vertically disposed with respect to a shaft 400. That is, the first wind turbine 300 is disposed to an upper part of the shaft 400, and the second wind turbine 350 is disposed to a lower part of the shaft 400. In the first wind turbine 300, a shaft fixing part 330 is fixed to the shaft 400, a wind turbine support pipes 310 are disposed to be opened from the shaft fixing part 330 at 120 degrees, and vanes 301 are disposed at the tip of the wind turbine support pipes 310. In the second wind turbine 350, the wind turbine support pipes 310 are disposed at an interval of 90 degrees from the shaft fixing part 330, and vanes 302 are disposed at the tip of the wind turbine support pipes 310. The first wind turbine 300 has a property suitable for power generation in higher in speed, i.e., higher in wind power energy than the second wind turbine 350. <P>COPYRIGHT: (C)2009,JPO&INPIT |
