The Analysis and Processing Method for the Vibration of 100MW Turbine-Generator Unit

The article is detail descripted a 100MW turbine that the abatement process of the abnormal bearing vibration on the turbine during the first start-up after the unit completed the outage.According to the vibration monitoring during the turbines start-up on site,the analysis and study to the data and curves of vibration monitoring was carried out.The reason of bearing's vibration is due to weight unbalance of generator rotor,to deal with the vibration by high-speed dynamic balance two times on site,the vibration of this turbines reach the fine standard.
