基于中微尺度嵌套的漂浮式风力机在台风-波浪耦合作用下的动态响应研究
Dynamic response of floating wind turbines under typhoon-wave coupling based on me so-micro scale nesting
摘要
Abstract
In recent years,offshore floating wind turbines have garnered significant attention due to their potential for efficient development of deep-sea wind energy.However,extreme weather conditions such as typhoons pose severe challenges to their structural safety.To address this issue,this paper constructs a typhoon-wave coupled simulation platform based on WRF-SWAN,simulating the coupled evolution process of the wind and wave fields of Typhoon"Sula"(202309).The simulation results are downscaled using the Solari spectrum and the JONSWAP spectrum,achieving a nested transition from mesoscale meteorology to microscale fluid dynamics.Based on this platform,the OpenFAST program is utilized to comprehensively analyze the dynamic responses of key components of the IEA-15 MW floating wind turbine under the conditions of the typhoon eyewall.The results indicate that in the typhoon eyewall region,the blade tip deformation and root loads are significant under idling conditions,while under parked conditions,the responses of the three blades show notable differences but the overall forces are smaller,making it more suitable as an operational state in the typhoon eyewall environment.Additionally,when the wind turbine is positioned upwind,it is prone to dangerous yaw angles,leading to severe aeroelastic oscillations of the blades;positioning downwind provides a safe yaw angle range of nearly 100 degrees,significantly reducing aeroelastic oscillations of the blades.The two operational states have a significant impact on blade responses,but their average impact on the tower base moment is less than 9%,indicating good adaptability of the tower base structure.关键词
