Abstract
The Wind Generation System (WGS) is an essential piece of equipment for the model test of the Floating Wind Turbine (FWT) in integrated wind & wave environment. With the evolution of FWT techniques, the requirements for the comprehensive performance of WGS are improved. In this paper, we develop a novel WGS with modular design philosophy, aiming to improve the temporal & spatial quality and controllability of the generated wind fields. 68 individually-controlled carbon fiber propellers are deployed in a hexagonal configuration to form a 4.2 m × 4.2 m wind generation area. Steady/dynamic and uniform/non-uniform wind fields can be reproduced, with the wind speed varying from 0 to 12 m/s. Extensive tests are conducted to assess the feasibility and performance of the proposed WGS. The statistical characteristics of the generated wind fields coincide well with the targets, demonstrating a satisfying comprehensive performance of the present WGS. Finally, the WGS is applied to evaluate a novel FWT concept in an integrated model test in wave basin. The FWT dynamic performances agree well with the expected ones from numerical simulation, further demonstrating that the proposed WGS could contribute to improving the accuracy and reliability of FWT model tests.
