Abstract: This paper analyzes and summarizes the continuous trip of a steam turbine generator unit caused by the oil film whirl of the support bearing on the generator side in a thermal power plant. The type of the steam turbine is the high temperature and high pressure, single cylinder, single extraction and back pressure. In this paper, the mechanism of oil whirl is discussed. The frequency spectrum analysis technology is used to analyze the cause of vibration. The cause of vibration is determined.
Key words: whirl；Spectrum analysis
