초록
Floating offshore wind turbines (FOWTs) have been developed to overcome large water depths and leverage theabundant wind resource in deep seas. However, wind-wave misalignment can occur depending on the weather conditions, and mostmegawatt (MW)-class turbines are horizontal-axis wind turbines subjected to yaw errors. Therefore, the power performance anddynamic response of super-large FOWTs exposed simultaneously to these external conditions must be analyzed. In this study, severalscenarios combining wind-wave misalignment and yaw error were considered. The IEA 15 MW reference FOWT (v1.1.2) andOpenFAST (v3.4.1) were used to perform numerical simulations. The results show that the power performance was affected moresignificantly by the yaw error; therefore, the generator power reduction and variability increased significantly. However, the dynamicresponse was affected more significantly by the wind-wave misalignment increased; thus, the change in the platform 6-DOF and towerloads (top and base) increased significantly. These results can be facilitate improvements to the power performance and structuralintegrity of FOWTs during the design process.
