Abstract

過去所發展的振盪水柱式波浪發電受到氣室設計影響，僅窄頻譜波浪可產生共振現象，難使其有較佳的能源轉換效率。在真實海域環境中，波浪頻譜包含許多不同頻率成分波且若又加上斜向入射，常使得原設計之振盪水柱式波浪發電效率低落。加上因淺化後的入射波能量較低，使得岸基式OWC的發電量較低。本研究計畫的目的為： (1) 藉由OWC氣室的寬頻共振設計與驗證，提升整體的轉換效率，克服傳統振盪水柱式波浪發電機低發電效率之缺點。 (2) 發展對較高擷取效率OWC的通用的設計程序與測試方法。 (3) 篩選出臺灣海域高波浪潛勢之波浪條件，對不同週期與入射方向之波浪條件下的OWC進行性能評估與確認。 (4) 協助建立臺灣波浪能發電的初期示範目標。The previously developed oscillating water column (OWC) wave energy converter is affected by the design of the air chamber. Only narrow frequency-spectrum waves can induce resonance, which makes it difficult to achieve better energy conversion efficiency. In the real sea environment, the wave spectrum contains many different frequency component waves and if the incident wave is oblique to the inlet of the OWC, the wave power conversion efficiency is often low. The power generation of shore-based OWC is lower than offshore-based or nearshore-based types since the wave energy becomes lower after shallowing. The objectives of this research project are: (1) With the broadband resonance design and verification of the OWC air chamber, the overall conversion efficiency is improved, and the shortcomings of the low power generation efficiency of the traditional oscillating water column wave generator are overcome. (2) Develop general design procedures and test methods for OWC with higher energy capturing efficiency. (3) The wave conditions of high wave potential in the Taiwan waters are selected, and the performance of OWC under wave conditions of different periods and incident directions is evaluated and confirmed. (4) Assist in establishing the initial demonstration target of Taiwan's wave power generation.
