摘　　要：本文详细介绍了某300MW机组在起动及带负荷运行过程中产生振动异常的处理情况。通过对整个机组进行开机全过程的振动监测,以及对振动数据的研究分析,确定了产生振动异常的主要原因是发电机转子质量不平衡。经过数次现场高速动平衡处理,并对其他产生振动的原因采取相应的处理,有效消除了机组的异常振动,确保了机组的安全运行。The paper gives a particular analysis on a 300MW turbogenerator that the abatement process of the abnormal vibration on the turbine during the first start-up and running with load.According to the vibration monitoring during the turbines start-up on site,the analysis and study to the data of vibration monitoring was carried out.The reason of bearing s vibration is due to weight unbalance of generator rotor.After several high-speed dynamic balance on site and othe corresponding malfunction disposal,the vibra...
