<P>PROBLEM TO BE SOLVED: To provide a wind power generation device capable of auxiliarily using stored compressed air. <P>SOLUTION: This wind mill power generation device comprises a differential gear device 13 having first and second side gears, first and second pinion gears, and a main gear, a generator 30 driven by the main gear 19, an air compressor 40 drivable by the main gear 19 through a rotational operation transmission means 43 and a compressed air tank 52, and an air motor 60 driven by the compressed air. The first side gear is rotatingly driven by a wind mill 11, the second side gear is rotatingly drivable by the air motor 60, and when the amount of power generation is in an excessive state, the compressed air is stored. When the amount of power generation is not sufficient, the air motor is driven to controllably hold constant the rotational speed of the main gear. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
