Abstract

地球温暖化対策およびエネルギー安全保障の観点から,再生可能エネルギー利用のさらなる進展が必要である.風力エネルギーは風速の3乗に比例して増加するが,経済性の向上には風況の良い場所の選定が重要となる.経済性の目安としては,ハブ高さ80mにおいて年間平均風速が7m/s以上とされている.陸上においては,全国風況データ,500mメッシュで解析した風況マップや風配図が提供されているが,日本沿岸海域においては,詳細な風況・波浪マップはまだ提供されていない.本研究は,今後の洋上風力発電施設の設置場所選定に役に立つように日本沿岸海域の風況・波浪マップを作成し,風と波の概況を把握するものである.

 Although the information of wind state on land around Japan is provided, the detailed wind information around offshore sea is not given. Offshore wind and wave information are necessary when planning an offshore wind farm for the use of natural renewable energy. The present study made mappings of detailed wind and wave conditions around Japan. It becomes clear that the annual averaged wind speeds at a height of 10 m from the sea surface, economical criterion of wind energy utilization, are greater than 6 m/s except near coastal regions. The average wind speeds for each of the four seasons and twelve months are also obtained. A user friendly information system was developed to indicate the values of wind speed and wave height at the same location.
