Study and Application of Ultra-Supercritical Turbogenerator Shafting Dynamics
In order to improve the thermal efficiency of steam turbines,the critical speed,unbalance response and stability characteristics of ultra-supercritical turbogenerator shafting were studied.It was found that the results meet the requirements of API684.During the operation of the unit in 168 h,the maximum axial vibration is less than 76 μm,and the vibration is stable and reliable.
