摘　　要：介绍了某电厂2号汽轮发电机组的轴系振动情况,分析认为机组振动的主要原因为一阶不平衡及转子热变形。通过转子动平衡,消除了机组的振动故障,使振动达到优良水平,保证了机组的安全运行。This paper analyzes the vibration problem of No. 2 135 MW turbogenerator unit in a power plant,and find that the vibration is mainly due to the first - order unbalance and thermal deformation of the rotor. After dynamic balance of the rotor, the vibration fault of the generating unit is eliminated with a better vibration grade to achieve safe operation of the generating unit.
