摘要
Turbogenerator shaft cracking is a serious problem of concern to turbogenerator manufacturers and power supply utilities. In this paper, vibration case histories are given for two occasions where large turbogenerator rotors (700 MW) were operated with propagating cracks. Vibration measurements were extensive, and so nearly complete pictures of vibration changes have been obtained. Several examples from the measurment results are given mostly in the form of diagrams. A description of the measurement system and the monitoring strategy is also given.
