摘　　要：随着风电行业的快速发展,风电机组装机容量快速增长并逐渐从内陆向海上扩展,这使得其运维的工作量与难度越来越大。而且,目前的偏航系统存在偏航电机去冗余设计以及缺少精细化传感器的情况,使得偏航系统驱动能力有所下降、偏航电机的工作情况无法及时准确掌握。针对这个问题,为了保证风电机组的稳定安全运行,文章提出了一种风电机组偏航电机转速监测的方法,该方法通过电感式接近开关实时监测偏航电机,并将信号传送给PLC用于速度计算与保护判断,可以及时检测和预防潜在的可能故障,减少停机时间。实验结果表明,采用此方法监测偏航电机的转速时,在所选择的5个转速下都有着较高的精确度,最大误差不超过3%,满足风电机组对于偏航电机转速监测的需求。With the rapid development of the wind power industry,wind turbines has experienced rapid growth in installed capacities and a gradual shift from onshore to offshore deployment,leading to increased workload and challenges in their operation and maintenance.In addition,existing yaw systems are equipped with yaw motors designed with minimal redundancy and a lack of fine sensors,which causes decreased drive capacity of these systems and hampers the timely and accurate acquisition of operational conditions for yaw motors.To solve these issues and ensure the stable and safe operation of wind turbines,this paper proposes a method for speed monitoring of yaw motors in wind turbines.The method employs inductive proximity switches to monitor yaw motors in real time.Monitoring signals are transmitted to programmable logic controllers(PLC)for speed calculation and protection judgment,to achieve timely detection and prevention of potential failures,thus reducing downtime and improving the economic efficiency of the entire wind farm.The experimental results showed that this method achieved high accuracy in monitoring yaw motor speed at five selected speed levels,with a maximum error of no more than 3%,meeting the monitoring requirements of wind turbines for yaw motor speed.
