Abstract
The smart fatigue load control of Up Wind/NREL 5 MW floating wind turbine on tension leg platform (TLP) is numerically investigated on our newly integrated aero-hydro-servo-elastic platform based on NREL FAST/AeroDyn open source code. The load condition of normal turbulence model (NTM) and normal sea state (NSS) under International Electrotechnical Commission (IEC) standard is chosen to examine the effect of deformable trailing edge flap (DTEF) control. It is found that DTEF significantly alleviates the fatigue loads on blade, driving chain and tower by up to 20%-35% compared to collective pitch control, enhancing reliability and economy for the system. Above rated wind speed, the auxiliary pitching function of DTEF regulates the generator speed to obtain steady and safety electric power and torque output, meanwhile relieving the wear of the blade pitch system, which further improves the performance of TLP floating offshore wind turbine. A detailed analysis based on DTEF is also carried out for the sake of exploring related mechanisms for its effectiveness.
