Review of hybrid model testing approaches for floating wind turbines

摘要

This paper presents a review of the hybrid model testing strategies for floating wind turbines. It examines the method’s accuracy, advantages, and weaknesses. The hybrid approach refers to tests that combine physical testing and numerical simulation in wave basin or wind tunnels. The coupling between the physical and numerical part is done via actuators. The different forms of hybrid testing adopted by researchers – such as robots, cable, propeller’s actuators – are discussed and evaluated. A guidance is given for selecting the hybrid style suitable for model testing. It is concluded that hybrid testing is cost-efficient and versatile but its fidelity relays on the accuracy of the numerical tool. Also, the test’s objectives are a key factor for choosing the suitable hybrid testing methodology.
