| Abstract: | In the operation of generator units in Shuibuya Hydropower Plant, a significant increasing of the vibration zone crossing is observed, which could induce the generation and enlargement of the fatigue failure zones in metal parts and weld joints and cause cracking and even breakdown of the units.To prevent the frequent vibration zone crossing and induced breakdown of the units, possible causes of this problem are analyzed.Treatment measures are proposed correspondingly to ensure the units operate in an optimal working condition. |
