本論文針對台東成功海域作為未來岸基震盪水柱式波浪發電系統預定廠址，並依據當地近岸波浪觀測資料與福祿數理論，將實驗規格等效縮小至本系造波水槽以完成初期測試。本文採用雙沉箱氣室結構並搭配使用兩級串接Savonius葉片，使流經葉片之合成風速較為穩定，以降低傳統震盪水柱式發電系統葉片轉速變化劇烈情形，並降低後端控制電路成本、提高發電機輸出功率品質。不同於一般此類波浪發電機構，本文採取平行於波浪前進方向之架構，並將沉箱氣室尺寸做最佳化設計，使波浪通過沉箱結構時可較穩定，其衰減量較小，亦即代表系統發電品質較為穩定，發電容量可以提升。本文依據水深、波浪週期與波浪長度作為沉箱尺寸最佳化計算參數，發電機規格則依據沉箱施予葉片流速、功率與葉片性能參數完成其整合設計。本文所設計之波浪發電系統，經實驗測試驗證其效能符合預期。

This thesis investigates the feasibility of applying oscillating water column (OWC) wave energy system to the onshore area in Taitung, Taiwan. A laboratory scale prototype of the OWC wave energy system is built based on the surveyed wave data at the target site. The prototype is scaled down using the Froude number theory for equivalence to the real site condition. The OWC is designed to have two chambers and two cascaded Savonius turbines, each of them being used for one chamber of the OWC. This configuration helps to stabilize the air flow passing the turbines so that the rotational speed the the turbines can be more steady than that with single chamber. Consequently, the cost on power electronics can be reduced and the quality of the power output can be maintained. The designed side-mounted OWC, differing from conventional systems, is structurally parallel to the propagation of the waves and allows the wave to penetrate the OWC. This will enhance the conversion rate for transferring wave energy to the chamber air, and thus the turbine. The OWC and the permanent-magnet generator are designed in a systematic manner for better system efficiency. The prototype is tested for performance validation.
