TANG Guangtong, ZHANG Weijiang, LI Ning, et al. Analysis and Treatment of Abnormal Vibration Anomaly in Steam Turbine of Gas-steam Combined Cycle Unit[J]. 2021, 40(5): 59-62.DOI:
There were many abnormal vibration problems occurred in steam turbine during the entire system startup of gas-steam combined cycle power plant
seriously affecting the safe and stable operation of the unit.On the basis of vibration analysis and testing
many problems were found with steam turbines
such as the critical speed and warm-up speed setting
vibration sensor bracket resonance and No.5 bearing installation fault.After treatment the unit runs normally with good vibration performance.That provide reference for same type units.
