Excessive Vibrations On 250-mw Turbo-Generator Bearings Due To Flexible Steel Foundations
4 PagesAPPLICATION NOTE Excessive vibrations on 250-MW turbo-generator bearings due to flexible steel foundations Excessive bearing vibration was detected during commissioning of a 250 MW turbo-generator at the Huntly Power Station. Further investigation determined that it was resonance caused by the flexible steel foundations used for earthquake protection.The optimal solution was a dynamic vibration absorber that was mounted directly on the
