| Abstract: | The critical transverse speed,power response and torsional inherent frequency of shafts for the Three Gorge water-turbine generator set were calculated with transfer matrix under the condition of taking account of many factors effecting on shafts,stability such as unbalanced quality,electromagnetism and water power.The results showed that the critical speed and power response of the shafts for the Three Gorge water-turbine generator set can meet the requirements for long-term steady operation and the torsional inherent frequency is not in the range of excitation vibration frequency. |

| Keywords: | water- turbine generator set critical speed power response torsional inherent frequency |
