由朱聖浩老師團隊所開發的離岸風機分析與設計程式WindTurb整合了IEC61400-3以及DNV GL所提供之設計載重組更進一步考慮地震以及疲勞，並針對NREL 5MW 參考風機進行支撐結構的設計。然而5MW的風機已經無法滿足現在的能源需求，為了使風機在發電上更具有競爭力，大型化是必然的趨勢。由於葉片尺寸的資料為風機製造商的商業機密，本研究以NREL 5MW 參考風機的參數為改變風機葉片尺寸的依據，以額定風速12m/s的條件下提供了等額定瓦數圖，以方便使人了解額定瓦數、半徑以及弦長的關係，並將大型化的參數整合於WindTurb，使用者只需在輸入檔開頭輸入三個參數即可更改風機的尺寸進行支撐結構的分析以及設計。最後針對最大容許饒度線上的尺寸進行IEC61400-3設計載重組分析，得到設計用鋼量與額定瓦數之間的關係。電腦輔助分析程式由 朱聖浩教授研究團隊所開發，分析程式與研究成果皆為公開資源。

The offshore wind turbine analysis and design program WindTurb developed by JU team integrates the design load cases provided by IEC61400-3 and DNV GL, further considering earthquake and fatigue, and design the NREL 5MW reference wind turbine support structure. However, the 5MW offshore wind turbine has been unable to achieve the current energy demand. In order to be more competitive in power generation, use large-scale offshore wind turbine is an inevitable trend. Since the blade size data is the trade secret of the wind turbine manufacturer, this study uses the NREL 5MW reference wind turbine parameters to change the blade size, and provides rated power contour with 12m/s rated wind speed to show the relationship between rated power, radius, and chord. After the large-scale parameters are integrated into WindTurb, the user can change the size of the offshore wind turbine to analyze and design the support structure by typing three parameters at the beginning of the input file. Finally, the size on the deflection limitation line are analyzed under the ultimate strength design load cases, and the relationship between the total design steel weight and the rated power is obtained. Note that the computer programs developed by the research team of Shen-Haw Ju are open and free to use.
