中文摘要 近年來綠色能源蓬勃發展,其中風能的發展備受矚目。台灣為熱帶、副熱帶季風氣候與地形影響,因此擁有許多良好的風場,但其缺點為每年都有強度大小不同的颱風過境。當極端風速來臨時,風力發電機將會超過其額定轉數,造成發電機、轉軸與葉片之損壞,因此往往以停機之方法處理。
  有鑑於此,本研究將致力於研發一台新式小型風力發電機,其擁有普利盤被動控制襟翼之機構設計,靈感來自於飛機之後緣襟翼(開縫式襟翼),能在低轉數時將葉片向壓力面彎曲增加翼型彎度,藉此提高葉片轉動時所產生之升力;在高轉數時能將葉片打向翼型吸力面造成失速現象,以此來降低風力發電機轉數、保護發電機與軸承並維持發電效率。
  本研究將利用Solidworks之繪圖軟體來進行普利盤機構與葉片襟翼機構之設計與改良,並利用ANSYS Fluent之CFD軟體進行數值模擬分析,以預測此機構是否可行,如經風洞實驗驗證可行,便進行田口方法針對低轉數區域之最佳化分析,設計出能在低轉數區域有最佳C_p值;在高轉數下能有效降低轉數並提供穩定功率輸出之適用於都會型風場小型風力發電機,提供一般家庭所使用。
英文摘要 This research will focus on the development of a new small-scale wind turbine with a passively pitch controlled flap design that is inspired by the trailing edge flaps (slotted flaps) that can be used at low revolutions. The flap bends to the surface pressure to increase the airfoil camber, thereby increasing the lift generated when the blade rotates; at high rotations, the blade can be driven toward the airfoil suction surface to cause stall, thereby reducing the number of wind turbine revolutions, protecting the generators and maintain power generation efficiency.
This study will use Solidworks to design and improve the Ply disk mechanism and blade flap mechanism, and use ANSYS Fluent's CFD software for numerical simulation analysis to predict whether this mechanism is feasible, such as wind tunnel test verification. The Taguchi method is optimized for low-turn areas, and has the best Cp value in low-turn areas. It can effectively reduce the number of revolutions and provide stable power output at high rotations. Small wind turbines are available for general household use.
