摘　　要：为抑制风电机组塔架左右(侧向)振动,提出在控制器的设计中,利用振动速度反馈来增加塔架左右方向结构阻尼的方法。首先对塔顶机舱左右振动加速度信号积分,得到振动速度信号,然后使用二阶带通滤波器得到塔架频率主成分,最后乘以增益系数并附加到发电机转矩中。以上海电气3.45MW高速永磁同步风力发电机组为研究对象,基于Bladed软件建模和Matlab平台对该控制策略进行调参和仿真验证,并首次应用于现场控制系统中。结果表明,所提出的速度反馈能够有效降低塔架左右振动加速度,在一定程度上降低了机组故障率,延长了风机寿命。该研究为风电机组主动减振方法设计及应用提供了实际参考。To suppress the side-to-side vibrations of the wind turbine tower,a method is proposed in the design of the controller by using vibration velocity feedback to increase the structural damping of the tower in the side-to-side directions.Firstly,the side-to-side vibration acceleration signals of the tower top cabin are integrated to obtain the vibration speed signal.Then,a second-order band-pass filter is used to obtain the main component of the tower frequency.Finally,it is multiplied by the gain coefficient and added to the generator torque.Taking Shanghai Electric's 3.45 MW high-speed permanent magnet synchronous wind turbine as the research object,the control strategy is adjusted and simulated based on Bladed software modeling and Matlab platform,and is applied to the on-site control system for the first time.The results show that the proposed speed feedback can effectively reduce the side-to-side vibration acceleration of the tower,reduce the failure rate to a certain extent,and extend the life of the wind turbine.This study provides a practical reference for the design and application of active vibration reduction methods for wind turbines.
