Turbine Rotor is one of the most important components of the Turbine-generator unit which is related closely with the safety and economy of the Power Plant’s Operation. In this paper the rotor design & analysis process for the Shanghai Turbine Plant’s super critical 600MW power station is introduced. Large thermal stresses maybe developed in the turbine rotors of the power plant during start-up, shutdown and load changes. The integrity of the turbine rotor is threatened by the material deterioration caused by fatigue and creep damage of the rotor at some critical locations. Rotor stress analysis using FEA is used to evaluate the strength and the temperature distribution of the turbine rotor. The life loss mechanisms of the turbine rotor are described. Key factors that influence fracture mechanisms are discussed. Rotor damage due to low-cycle fatigue, high-cycle fatigue and creep damage are discussed as the main elements to evaluate the life time of the turbine rotor.
