本研究是要設計一無段變速控制器,能根據風速以及飛輪轉速自動調整其變速比,使飛輪更快速且有效率的累積至可壓縮空氣的轉速,並使風車操作在最大輸出功率下,讓風能轉換成壓縮空氣的效率能提升。 本研究會先介紹善用風力壓縮空氣儲能的系統架構及系統中各部份的功能,敘述整體系統如何將風中的能量轉換成壓縮空氣作儲存。 本研究將照著變速控制器設計流程圖的步驟依序來進行分析與設計, 以機械式變速控制器為首要目標來設計,完成後評估其效率與可行性,同時設計電子式變速控制器。 控制器設計完成後,本研究繪製一效率比較圖,比較風車直接驅動空壓機的效率與本研究設計的飛輪儲能系統壓縮空氣的效率,藉此獲得一參考比較的基準。
The purpose of this research is to design a controller of a continuously variable planetary transmission(CVP). The controller can adjust the gear ratio based on wind speeds and the rotational speed of a flywheel. With this controller, the flywheel can rapidly reach the rotational speed which is suitable for compressing the air into a tank. Also, a wind turbine can be operated at the best efficiency point with this controller. Therefore, the efficiency of transforming wind energy into compressed air improves. Structure of pneumatic storage system with the turbine as well as the flywheel and how each part functions will be introduced. How the wind energy transforms into the compressed air in the system will also be illustrated. The process of designing the controller is followed in the research. A mechanical controller is a priority to design, and the efficiency and the availability are analyzed after the design of mechanical controller. If the result is not as good as estimated, the design of an electronic one will be adopted. After the design of the controller is finished, an efficiency comparison will be proceeded as a reference to improve. The two systems compared are one which punches the air directly driven by the turbine and another, we design, which punches the air by the energy stored in the flywheel.
