摘　　要：综述汽轮发电机组轴系扭振产生的原因及轴系扭振抑制方法与技术的研究进展,重点介绍次同步谐振引起的扭振抑制技术的研究现状。结合当前研究探讨了磁极表面加装阻尼绕组、加装滤波装置及混合串联补偿装置等抑制扭振的方法并指出其现存的不足之处。最后,就这些问题对本领域的研究发展趋势进行了展望。The causes of the torsional vibration of turbine generator shaft and the research progress of shaft torsional vibration suppression methods and technologies are reviewed. The research status of the suppression technology of torsional vibration caused by subsynchronous resonance is emphasized. Combined with the current research, the methods of suppressing torsional vibration such as damper winding, retrofit filter device and hybrid series compensation device are discussed, and the existing deficiencies are pointed out. Finally, the research trends in this field are prospected for these problems.
