An unplanned shutdown occurred in a 650MW unit after one year of commercial operation. In the subsequent start-up, due to the excessive rubbing vibration, the unit tripped many times. During the overhaul inspection, it was found that the foundation of the steam turbine had large uneven settlement. Through taking proper maintenance measures, the vibration problem was successfully solved.
