摘　　要：针对某台600 MW超临界汽轮发电机组出现的轴系振动异常现象,通过运行参数及振动数据,对#1、#2和#3、#4轴承相对轴振偏大问题、#4和#5轴承座振动大问题进行了研究,最终通过现场动平衡试验解决了该机组轴系振动问题。The vibration cause of HP-IP rotor, the LPⅠrotor and bearing seat for one 600 MW unit were confirmed by test analysis. Through carrying out dynamic balancing, the vibration of the unit has been lowered into a qualified range.The treatment practice indicates that the fault diagnosis method and the treatment measures are effective.
