摘要

近年來風力發電產業漸漸往離岸型發展，目前歐洲各國已有多處近岸式風力發電廠。未來要進一步發展必需往深水區域架設浮動式風力發電機，浮動式風力發電機是將浮體平台與風力發電機結合成一個系統，此系統會同時受到空氣動力和水動力的作用下而產生運動行為，浮體平台必須要有足夠的穩定性才能讓發力發電機正常運作，於是整個系統受外力後的運動行為相當重要，本論文研究浮體式風力機受到波浪力和風力作用時所產生的動態響應行為。在風力計算上採用葉片元素動量理論，而波浪力乃針對Spar型浮體採用莫里森方程式，並推導出浮體式風力機的運動方程式。本研究將上述理論撰寫成一個計算程式來解析浮體式風力機的運動方程式，程式命名為NTUOE-Spar，並將程式之計算結果與文獻做比較驗證。最後，本研究對於一個斜張式錨鍊Spar型浮體式風力機模型進行了水槽模型實驗，並以NTUOE-Spar進行數值計算，實驗結果加以比較分析，進一步確認程式計算之可行性。

Recently the wind industry moved to offshore areas. The floating wind turbine combined the platform with wind turbine into a system. This thesis is studying the dynamics response of the floating wind turbine. The primary loads of floating wind turbine are wind and wave force. In this thesis, the equation of motion of floating wind turbine had been derived. The wind force is calculated by blade element momentum theory and the wave force is calculated by Morrison’s equation. Base on above theories, this thesis developed a code named NTUOE-Spar. The code had been verified by code-to-code comparisons with NREL OC3-Hywind system model. A spar type floating wind turbine model test had been conduct, the result of the experiments had been compared with NTUOE-Spar simulation.
