300MW汽轮机组汽流激振问题的分析及处理

Analysis on the Cause of Steam Flow Excited Vibration of a 300 MW Steam Electrical Generating Unit

针对某热电厂2×300 MW机组整套启动试运中出现汽流激振问题进行深入分析,查找振动原因,对振动性质做出判断,提出了解决问题的方法,制定了相应的预防措施,消除了机组自激振动,取得了良好效果。

The steam flow excited vibration problem of Two 300 MW thermal power generating units in a thermal power plant was analyzed, the cause for the steam exciting was found. Based on the conclusion for the vibration property, solutions to the problem and precaution measures were given. After the application of the given measures, the self excitation vibration of the units was avoided.
