To meet the needs of offshore wind power development in medium depth water and reduce the cost

an articulated wind turbine was designed based on articulated platform. The influence of turbulent wind on the dynamic response of the articulated wind turbine in working and extreme sea conditions was studied. The blade element momentum theory was utilized to calculate the aerodynamic load and the potential theory was applied for the simulation of wave load. Considering the coupled loads of wind

wave

and current

the instantaneous change in wet surface as well as the friction damping of the articulated joint

a calculation software was written and time domain dynamic response of the wind turbine was calculated. Based on the NPD spectrum of turbulent wind

the dynamic response of the articulated wind turbine under the loads of constant wind and turbulent wind were calculated

and the influence of turbulent wind on the dynamic response and energy efficiency of the wind turbine was analyzed. Results show that with turbulent wind

the wind wheel acceleration and the vertical pull force on the articulated joint had little change. The mean values of oscillation angle

stream-wise thrust

output power

and stream-wise thrust force on the articulated joint decreased

but the amplitudes of oscillation angle and output power increased. In addition

the low-frequency characteristics of turbulent wind could increase the low-frequency response of the system and thereby cause system resonation. In extreme climate condition

the maximum stream-wise oscillation angle of the articulated foundation increased significantly

but the turbine system still met survival requirements. Hence

turbulent wind has great influence on the dynamic response of articulated wind turbine

and it is necessarily to consider the impact of turbulent wind when analyzing the movement and strength of articulated wind turbines.
