Abstract
波からエネルギーを取り出し発電を行う波力発電装置において、荒天時の波力発電装置の故障等を防止することのできる波力発電装置及びその制御方法を提供する。
【解決手段】
胴体3と、胴体3に沿って上下運動する発電ブイ2と、発電機構を有する波力発電装置1において、発電ブイ2が、ブイ本体21と、ブイ本体21に固定され内部に気体Aを充填した膨張体22を有しており、波力発電装置1が、荒天時に膨張体22内の気体Aを外部に放出し、発電ブイ2を海面下に沈降させる荒天制御を行う構成を有している。
【選択図】図1
Description
、津波の発生等、検知から波の到来まで時間が短い場合であっても、発電ブイ2を迅速に海水中に沈降させ、波力発電装置の故障を防止することができる。また、復旧作業を容易且つ迅速に行うことができる。
