Beschreibung
Zusammenfassung:	The invention discloses a steam turbine blade operation risk monitoring method and system, and relates to the technical field of data processing, and the method comprises the steps: setting a temperature measuring point according to last two-stage blades, carrying out the blast working condition monitoring of the last two-stage blades of a low-pressure cylinder, obtaining a blast risk coefficient, and carrying out the early warning of the temperature of the blades; a vibration sensor is used for conducting flutter working condition monitoring on the last two-stage blades of the low-pressure cylinder, flutter working condition monitoring data are obtained, blade strength and vibration risk assessment is conducted, blade strength and vibration risk assessment results are obtained, and blade vibration early warning is conducted; and constructing a water erosion risk assessment model, performing water erosion risk assessment, obtaining a water erosion crack risk assessment result, and performing blade replacement
