本文之首要目的在於使用葉片動量元素法，設計及分析400w水平軸式風力發電機之轉子葉片，並於低速環境風洞進行全尺度實驗。在葉片設計部分將使用葉片最佳理論進行葉片外型設計，並使用葉片動量元素進行葉片之初步性能計算，在計算過程導入葉尖壓損及空氣阻力之影響，觀察在各風速下葉片扭矩變化及各尖速比下葉片功率系數之變化情形。實驗部分最後將使用低速環境風洞進行測試，透過調變負載改變尖速比，觀察輸出扭力及轉換效率之變化，且經由實驗定義出各風速下之葉片最佳操作區間，以利未來設計電控系統之控制策略。最後將葉片動量元素法分析結果與實驗相互比較，可得知葉片動量元素法預測結果與實驗值之空氣動力驟變點與操作點有相當程度上的穩合。綜合以上實驗結果可得知葉片本身之翼型、升阻力特性、實度、尖速比和發電機匹配性均會影響發電機整理性能。

In this thesis, the blade element momentum theory was utilized to design and analyze a 400 watt horizontal axis wind turbine rotor. A Full scale wind tunnel experiment is also performed to confirm the rotor performance. The optimum rotor theory was applied to design blade shape. Next, the blade element momentum BEM theory was used to predict the rotor’s aerodynamic performance. The modification methods, such as tip-loss factor and drag effect were considered in BEM theory. The rotor performance prediction was performed at different wind speed and tip speed ratio TSR. At last, an environment low speed wind tunnel that was conducted to experimentally investigate the rotor performance for comparison with the previous predictions. The power and transform efficiency were measured at different TSR, Further, the optimum operation region could be identified via the wind tunnel experiments, which is important for an electric of control designer to define a proper control strategy. In addition, the BEM theory and wind tunnel experiment results, it can be seen that the results of the BEM theory match very well with the experimental results. As previous mention, the rotor characteristics can affect the entire wind turbine performance, such as shape of airfoil, lift and drag curve, solidity, tip speed ratio and generator matching problem.
