Chinese Abstract

台灣具有相當優良的風場條件,使離岸風力發電成為台灣目前極力推廣的再生能源之一。過去套管式離岸風機支撐結構主要針對極端環境條件下進行極限負載的分析與設計,而本研究將著重探討疲勞負載下的損傷分析與使用年限設計。本研究根據規範DNVGL-RP-C203開發離岸風機疲勞分析與設計相關程式;先針對套管式支撐結構進行接頭型態評估,再使用雨流計數法配合S-N curve 與Miner’s rule計算疲勞損傷;最後使用Broydeb’s method對桿件厚度進行數值運算,達成離岸風機疲勞壽命目標值,例如為20年的使用年限。整合離岸風機支撐結構有限元素模型與設計載重組合成一個輸入檔,先後考量極限負載與疲勞負載,待程式自動化讀取桿件斷面進行有限元分析後,根據API RP 2A-LRFD鋼結構設計規範進行離岸風機支撐結構最佳化設計,如此以得到支撐結構所需的總用鋼量。最後運用多機平行運算技巧,將使windturb.exe成為一套更加完整且具效率的離岸風機分析與設計程式,並提供業界工程作為可靠的參考資源。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。

English Abstract

Taiwan has a very good condition of the wind field, making the offshore wind power has become one of the most widely promoted renewable energy sources in Taiwan. In the past, the jacket-type offshore wind turbine support structure was mainly for ultimate load analysis and design under extreme environmental conditions. However, this study will focus on the damage analysis and the service life design under fatigue load. In this thesis, according to the specification of the DNVGL-RP-C203 development the offshore wind turbine fatigue analysis and design programs. Firstly, the joint type of the support structure was classified, and then the fatigue damage was calculated by the rainflow counting method combined with S-N curve and Miner's rule. Finally, the Broydeb's method is used to calculate the thickness of the member to reach the offshore wind turbine fatigue life, e.g. with a service life of 20 years. Integrated the support structure finite element model and design load cases into an input file. After considering the ultimate load and fatigue load, the program will automatically read the section of each member for finite element analysis, and conduct the optimal design of the jacket-type foundation by using the API RP 2A-LRFD steel structure design specifications. Therefore, the total design steel weights of the support structure are obtained. Finally, using multi-machine parallel computing techniques will make the windturb.exe as a more complete and efficient analysis and design program of the offshore wind turbine, and provide the engineering industry as a reliable reference source. Note that the computer programs developed by the research team of Shen-Haw Ju are open and free to use.
