Vibration control of steam turbine of a 1000MW ultra-supercritical reheat uni
The shaft vibration of No.3 bearing box of a 2×1000MW ultra-supercritical secondary reheat unit of Harbin steam power plant reached the trip protection action during the running period,resulting in the unit outage.After analyzing the impulse starting parameters and TDM of the unit TSI and other data were analyzed,and through calculation,a counterweight was added to the intermediate pressure rotor of the steam turbine to address the vibration problem of the steam turbine.
