No.6 of a 600 MW supercritical steam turbine in a power plant is relatively large. In order to solve this problem
the intake mode of the steam turbine was changed by prolonging the operation time of the mixing valve with the initial load to make the steam turbine expand sufficiently
which improved the differential expansion of the high pressure cylinder
and the bearing load was also changed to reduce the bearing vibration
then the steam turbine vibration can reach the optimal state.
