description: The given work is devoted to studying and calculation of high-power steam turbines, in particular, a 1200 MW installation. The research set the following goals: 1. Calculation of the steam turbineâs thermal scheme. 2. Calculation of the am turbineâs flow part. 3. Modeling a turbine blade. 4. Calculation of the main turbineâs elements stresses. 5. The choice of protection method against the turbine blades erosion. The prototype for the turbine considered in this work is the K-1200-240 LMZ steam turbine unit. A calculation for the regenerative heating cycle was made here, also gas-dynamic and strength calculations of a low-pressure cylinder. For calculations here were used the programs SolidWorks 2018, Ansys Workbench 19.2, KOMPAS-2018, etc. The study resulted into a drawing of the low-pressure cylinder construction. A 3d-model of the turbine blade and turbine wheel of the low-pressure cylinderâs fourth stage, as well as a 3d model of the low pressure cylinderâs rotor have been developed. The static and dynamic strengthâs calculations of these elements have been done. Here was suggested method for protection against erosion of the last stages blades - electrospark alloying. The results of the work can be used by students of engineering specialties in the study of disciplines related to the steam turbines.
