| Abstract: | Aiming at the large horizontal vibration of upper bracket for #1 unit of Fengshuba hydropower station, the cause of vibration fault was analyzed. The dynamic balance test of the unit was implemented by using influencing coefficient method. The vibration of upper bracket decreased synchronously. The influence of mechanical and electromagnetic force was solved effectively. And it was verified that the unit is in stable operation at the conditions of increasing load through stability experiments. The vibration maintained at a value within the lower range. |
