WIND POWER GENERATING SYSTEM AND WIND POWER GENERATING METHOD

PROBLEM TO BE SOLVED: To provide a wind power generating system that can efficiently operate with respect to variation in wind force and obtain stable output, and to provide a wind power generating method.SOLUTION: The wind power generating system include: a generator; a rotation shaft; and a mass movement unit. The generator supports a windmill part rotating by wind force and generates power by the rotation of the windmill part. Rotation force from the windmill part is transferred to the rotation shaft. The mass movement unit has an annular part supported by the rotation shaft and changes radial mass between the annular part and the rotation shaft according to the rotation of the rotation shaft. 【課題】風力の変化に対して効率的な運用が行え、安定した出力を得ることができる風力発電システムおよび風力発電方法を提供する。【解決手段】風力発電システムは、発電機、回転軸、質量移動装置を備える。発電機は風力で回転する風車部を支持し風車部の回転により発電する。回転軸には風車部の回転力が伝達される。質量移動装置は回転軸に軸支された円環部を有し、回転軸の回転に応じて円環部と回転軸との間の径方向の質量を変化させる。【選択図】図１
