摘要
为了探究波浪能发电装置对不同功率的漂浮式风浪能联合发电系统动力学特性的影响,将发电装置分别与5 MW和15 MW的漂浮式风机平台结合,利用SIMO-RIFLEX数值框架构建了气动-水动-结构弹性-系泊全耦合多体动力学模型。分析两种系统在浮体运动、风轮推力和转矩以及塔基弯矩方面的差异,探讨波浪能发电装置对原始风机平台动力响应的影响。结果表明,波浪能发电装置使5 MW风机平台系统的共振频率进入波频范围,显著增加了垂荡和纵摇运动的剧烈程度,而对于15 MW风机平台系统则提升了它的稳定性。此外,波浪能发电装置的加入对5 MW系统气动载荷的标准差有显著的放大作用,而对15 MW系统的影响则较有限。
This study investigates the effects of wave energy converters(WECs)on the dynamic behavior of floating wind-wave hybrid power generation systems with different power capacities.Two configurations are analyzed:a 5 MW and a 15 MW floating wind turbine,each integrated with WECs.A fully coupled aerohydro-elastic-servo multi-body dynamics model is developed using the SIMO-RIFLEX numerical framework.By comparing floating body motions,aerodynamic thrust/torque,and tower base bending moments between the two systems,the research evaluates how WECs alter the dynamic response of standalone wind turbines.Results demonstrate that WECs shift the resonance frequency of the 5 MW system into the wave frequency band,markedly amplifying heave and pitch motion amplitudes.In contrast,WECs enhance platform stability in the 15 MW system through damping effects.Additionally,WECs substantially increase aerodynamic load variability(standard deviation)in the 5 MW system but exhibit negligible influence on the 15 MW system.
