PURPOSE:To efficiently acquire electric power from a low load to a high load and to a specified load by arranging a large number of small generators as a generator and connecting each of generators to these small generators with a large number of planetary gears as output ends from a rotation axis of a turbine through a planetary gear device. CONSTITUTION:Wind energy is converted to rotational energy by vanes 1 of a turbine, it is accelerated by accelerating gears of a planetary gear device 2 and it is made to be necessary rotating speed for a generator 4. A plural number of planetary gears 3 constituting a second acceleration part in the planetary gear device 2 of an acceleration device are fixed in position by making first stage acceleration a star type and second stage acceleration a planet type, and accordingly, one each of small generators 4 arranged in parallel in a nacelle 5 is respectively installed on each of their output axes. Subsequently, the nacelle 5 is fixed on a tower 6 on a base. Consequently, the number of generators to drive is changed in accordance with wind force, and it is possible to improve efficiency and a power factor. |
