摘　　要：针对变速变桨(VSVP)风力发电机组如何抑制传动链的扭转振动进行研究。提出了使用卡尔曼滤波对轴扭转角速度进行估计与在反馈环节上施加反馈增益相结合的扭距控制策略。以三叶片变速变桨风力发电机组为验证对象,基于Bladed软件平台对直接速度反馈控制策略与施加了卡尔曼滤波和反馈增益的控制策略进行仿真比较。结果表明:相对直接速度反馈变控制,提出的转矩控制能使风力发电机组传动链的扭矩尖峰明显减小,并降低了发电机输出功率的波动。For large VSVP（variable speed variable pitch,VSVP）,the control strategy about how to suppress the drive train torsional vibration was researched.Kalman filtering was used in this paper to estimate the angular velocity of the shaft combined with the feedback gain in the feedback loop control strategy.Taking three-blade wind turbine as the research object,based on the Matlab software,this control strategy was simulated.The simulation results of the proposed control strategy show that compared with the direct velocity feedback control,the proposed torque control can reduce significantly the peak torque and the fluctuation of output power.
