As a renewable non-polluting energy, wind energy has a good development prospect and development advantages. Nowadays, onshore wind power construction technology is relatively mature, and there is still a lot of room for the development of infrastructure technology for offshore wind energy resource utilization, and its related research is gradually becoming the focus of new energy development. The offshore wind power foundation has many similarities with onshore wind power, while the deep-sea wind power often adopts a floating foundation due to factors such as cost and construction difficulty.
In order to learn the design process and performance analysis of the offshore floating wind turbine foundation, this article discusses the current domestic and foreign research progress of the offshore floating wind turbine foundation, summarizes the design research mainly applied to the theoretical basis of calculations, and discusses the types of offshore floating wind turbine foundations. Discussed.
Through the discussion of the above content, this article starts with a three-buoy foundation structure, builds the foundation of two other floating wind turbines designed with different ideas, and establishes its numerical model through SolidWorks. Select the appropriate parameters and use the fluid analysis software AQWA to perform frequency domain analysis on the foundation of the three different structures of the fan. It is known that the rolling and pitching of the floating wind turbine foundation and the bowing under certain conditions have a sensitive range of motion response to the wave frequency, and the wave direction has little effect on the results of heave and bowing. By comparing the results of the three models, it is known that different structures will affect the sensitivity range of the basic structure to wave frequencies.
