| Abstract: | Three corresponding calculating procedures were laid out based on the traditional principle of thermodynamic calculation of steam turbine,by analysing the underlying data needed for thermodynamic calculations of turbine under variable operating conditions.The procedures were implemented respectively on a 300MW steam turbine,on which thermodynamic calculations under different operating conditions were completed.Comparing between the calculation results and the design values showed that the three procedures were feasible,and the calculation accuracies satisfy the requirement of engineering applications well. |
