摘要：
Based on the actual parameters of the drivetrain of a new 8 MW semi-direct-drive wind turbine，the electromechanical model of the drivetrain is established，by changing the control strategy，the anti-interference ability of the wind turbine drivetrain is enhanced and the transverse vibration of the components of the drivetrain is reduced. The results show that when the wind turbine is excited by change，under the variable coefficient sliding mode controller，the speed tracking effect of the generator rotor is better，the transverse vibration displacement of the mechanical parts is reduced significantly，and the mechanical frequency of the generator current and the electromagnetic torque is effectively suppressed. © 2023 Science Press.
