水轮发电机组调试期间的常见问题

Common problems in the debugging period of hydroelectric generators

以某水电站35MW水轮发电机组在调试期间存在的异常振动现象为例,介绍水轮发电机组首次振动的数据,分析造成水轮发电机组振动的根本原因,得出水轮发电机组振动问题的治理效果,以期解决水轮发电机组异常振动这一常见的故障问题,从而确保水轮发电机组的安全稳定运行。

Taking the abnormal vibration phenomenon of 35 MW hydro-generator set in a hydropower station during commissioning as an example,this paper introduces the data of the first vibration of the hydro-generator set,analyses the fundamental causes of the vibration of the hydro-generator set,and obtains the treatment effect of the vibration problem of the hydro-generator set,with a view to solving the abnormal vibration of the hydro-generator set,and ensure the safe and stable operation of hydroelectric generating units.
