"本計畫擬針對點擊式波力發電機型式，研擬一新型之點擊式波力發電機，並於大斷面水槽中以規則波及不規則波進行水工模型試驗，計畫的進行主要分成三個階段，每個階段皆在測試達到較佳狀況後，再進行下一階段。本研究所研擬的點擊式波力發電機組主要分成波能擷取系統、能量傳輸系統及能量轉換系統等三個系統。各系統均分別進行測試。第一階段為波能擷取系統之設計，點擊式波能擷取系統主要利用浮筒吸收波浪能量，浮筒的形狀、構造與特性將影響擷取波能的效率，因此第一階對針對浮筒特性進行檢討與測試，檢討的參數包括附加質量、輻射阻尼、自然振頻等。第二階段為波能傳動系統的測試，本計畫波能傳動系統包含可逆式齒輪及增速齒輪，試驗時測試增速機與可逆式齒輪對擷取系統與發電效能之影響，檢討的參數包含增速比、可逆式齒輪直徑與浮筒上揚力之關係、齒輪間距之影響等，最後階段測試為發電機發電功率之量測與分析，本研究之波力發電機直接以發電機發電，檢討範圍包含發電功率、發電穩定性及發電效能。就本計畫之目標而言，希望能研發一適合台灣季節風浪較小波高時，仍能維持較高擷取效能與發電效能的波力發電機，同時在颱風季節時能較不受颱風影響，因此本計畫所研擬的點擊式波力發電機主要以岸繫式為主要型式，期望藉由本計畫的執行完成，課做為未來下海測試之設計參考。""This project presents a new type wave energy converter, to investigate and plan forward the wave power generator type; we used the snake-type wavemaker for irregular wave hydraulic model tests. The project is performed in three steps, each stage is to achieve a better situation after the test, and then proceed to the next stage. The main of the wave power generator is energy capture systems, energy transfer systems and energy conversion systems. Each system was full experimented in detail. The first step of wave energy capture system design is use floats to absorb wave energy, structure and characteristics of buoys to capture wave energy will affect the efficiency and comparative with the added mass, radiation damping, and the natural vibration frequency and so on. The second step is experimental of wave energy transfer system, this project includes reversible wave energy transfer system and overdrive gear, when the growth rate of pilot testing machine with reversible gear influence and power generation efficiency of the capture system for review of relationship buoy up power ratio, the impact of growth, reversing gear and the gear pitch diameter to include, etc., the final step is experimental and analysis for the power the generator power, this study the hydroelectric wave generator was obtain electricity generator, stability and power generation efficiency. The project is concerned, in the future we will hope and developing a small wave for Taiwan storm season high, and still maintain high performance and power efficiency to capture wave power generators, while the typhoon season can be more unaffected by the typhoon. Therefore this project aim is conclusions the wave power generators type, expected by the implementation of this project is completed; we will carry out a sea wave survey and would be investigated in future study."
