Regarding the sudden vibration fault of a steam turbine in a self-provided thermal power plant,based on analysis of the fault phenomena,vibration trend and vibration spectrum,the cause was concluded to be blade fracture,and the causes of blade fracture were further analyzed.Considering the stream turbine needs to be resumed for production as soon as possible,through comparison among several schemes,symmetrical blade cutting was selected,and achieved good results after the implementation.
