Huntly Power Station has 4 250 MW steam turbo-alternators which were commissioned between 1982 and 1985. During commissioning the vibration testing identified that the generator inboard bearing had high vibration at 100 Hz which is 2X the running frequency. This paper looks at the investigation into the cause of this high vibration and how it was reduced by the application of two tuned mass dynamic vibration absorbers.
