摘　　要：介绍了近期河南电网相继投产的几台600MW机组在试运过程中的振动问题,通过现场测量试验,对机组振动特点与原因进行诊断分析,针对不同厂家的机组振动情况,采取相应措施,进行治理。试验结果表明,诊断结论正确,采取措施恰当,获得了良好效果,对新机试运有一定借鉴意义。Vibration problem occurred during trial operation for several 600MW units in Henan electric power system is introduced. Through field measurement and test, the characteristic and reason of the vibration were diagnosed and analyzed. Based on unit＇s vibration in different power plants, relevant measures had been taken to solve this issue. The results show that the analysis and measures taken correctly have significance of new units.
