Experimental Calculation and Analysis of Thermal Performance for Steam Turbine of Nuclear Power Plants

Small deviation heat balance method can solve the calculation problems of steam turbine wet steam zone,and characteristic flow area of steam turbine can be used for the performance calculations and analysis of steam turbine flow area.In this paper,both methods are used in the experimental calculation and analysis of thermal performance of the nuclear power steam turbine,and the results are verified by the performance test on No.3 turbine in Ling’ao Phase II,and test calculation method are proved to be accurate and reliable.
