单缸单转子150MW汽轮发电机组振动原因分析与处理

Cause Analysis and Treatment for Vibration of 150MW Single-cylinder Single-rotor Turbo-generating Unit

单缸单转子150 MW(135 MW)机组是国内首创的新型汽轮发电机组,在四川投运的几台机组基本上都存在振动较大的问题,从一台机组的振动处理入手,简单分析了引起该类机组振动的原因。

150 MW （135 MW） single-cylinder single- rotor unit is a new kind of turbogenerating unit pioneered in China, but there is the strong vibration existing in several units which have been put into operation in Sichuan. Starting with the vibration treatment of a unit, the causes leading to unit vibration of this kind are analyzed in brief.
