摘　　要：内蒙古国华准格尔发电有限责任公司330 MW汽轮发电机组大修后一直存在发电机前瓦轴振动值大的问题。从激振力及基础支撑动刚度等方面,对可能引发机组振动故障的原因进行了逐一排查。分析认为发电机地脚载荷分配不均、支撑动刚度降低是引发机组振动故障的根本原因。通过检修处理,重新对发电机定子基础垫片进行调整后,彻底解决了机组的振动问题。One 330 MW turbogenerator unit present vibration value high after overhauling in Inner Mongolia Guohua Zhungeer Power Generation Co.,Ltd. From the aspacts of exciting force of vibration and foundation support dynamic stiffness, checked the reasons one by one which might cause vibration. Believed that the anchor load distribution uneven and the generator support dynamic stiffness reduction was the root cause of the vibration problem. Through repairing, re-adjustment of generator stator base gasket, completely solved the vibration problem.
