This paper conducts a three-dimensional modeling of the high-pressure inner cylinder of a 1000MW unit steam turbine by scanning it on-site and combining it with the installation diagram.The model was processed and meshed in the finite element analysis software.Take the temperature and pressure at the inlet and outlet of the high-pressure inner cylinder during peak load regulation of the unit for a certain period of time,and load the temperature and pressure in stages to the inner wall of the inner cylinder where the moving and stationary blades are located.The temperature and stress fields of the high-pressure inner cylinder were calculated under steady-state and variable load conditions.Laying a solid foundation for the analysis of life damage of steam turbine components during peak shaving in the future.
