摘　　要：在分析风电机组偏航系统结构特点的基础上,综述了电机驱动型主动偏航系统的故障类型及对应的故障机理、常用的故障诊断技术与方法的研究进展。经过文献分析发现,大功率风电机组电机驱动型主动偏航系统故障诊断技术的研究主要集中在大数据平台研究、多传感器信息融合技术开发等热点领域。未来,风电机组偏航系统故障诊断技术研究将以成本较低的基于SCADA系统的数据深度挖掘为发展方向。In this paper,the structure of yaw system of wind turbine is characterized. The fault types and related corresponding mechanism,fault diagnosis techniques are summarized. Through literature analysis,it is found that large data platform and development of multi-sensor information integration technology are the key issues on fault diagnosis technology for motor-driven yaw system of high power wind turbine. It is predictable that deep development of SCADA-based system will be the next fault diagnosis techniques of wind turbines.
