摘要

基于某公司新型8 MW半直驱式风电机组传动链实际参数建立传动链机电控耦合模型,设计机侧变流器速度环变系数滑模控制器,通过采用改变控制策略来增强风电传动链抗干扰能力并减小传动链零部件横向振动。结果表明：当风电机组受到外部突变激励时,在变系数滑模控制器控制下发电机转子对速度追踪效果更好、机械部件横向振动位移显著减小且发电机电流及电磁转矩中的机械频率得到有效抑制。

Abstract

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.
