碩士 / 國立成功大學 / 土木工程學系 / 106 / 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.
