Rotor Dynamics Analysis of 6MW Turbine Rotor-Bearing System

Lateral Torsional Critical Speed analysis was conducted to evaluate the 6 MW Steam Turbine rotor bearing system and torsional train comprising steam turbine, gearbox and generator respectively as per API 612 Standard. The operating speed of the turbine was 6750 CPM. The 4-pole generator operates at 1500 CPM.
