We were pleased to have had Wang Shuang from Chongqing University ​​​​​​​present at the 5th Wind & Drivetrain Conference 2022

Wang Shuang, 2nd Doctor of Chongqing University, is currently majoring in Mechanical Engineering at the College of Mechanical and Vehicle Engineering, Chongqing University. 
Wang’s research targets the digital design of key components of large wind turbine units, including parametric pitch design, yaw bearing systems, and the dynamic analysis of drive chains.
Over the past two years, she has taken charge of precise dynamic modeling and structural vibration control of wind turbines.

Abstract:

In order to simulate the performance of wind turbines with high precision, an aero-hydro-elastic-control coupling simulation model of the offshore wind turbine under wind-wave-seismic excitations is established based on the multibody dynamics model, which includes blades, towers, and drivetrains. Using Simpack, the model is combined with the seismic excitation model, hydrodynamics, aerodynamics, and the pitch-torque control system. 
Because of the wind shear effect and the output power fluctuation caused by the change of wind speed and the unknown disturbance of the system, a variable speed pitch control strategy based on active disturbance rejection is adopted to suppress the output power fluctuation. 
The control model is established through MATLAB/Simulink, which can effectively suppress system vibration and reduce the imbalances of yaw and pitch moments. 
In addition, the wind turbine dynamic model is coupled with the TMD system to conduct the wind turbine's response analysis under wind-wave excitations with TMD control under multiple operating conditions.
