Abstract
Based on the special requirements of on line supervision of the thermal efficiency of thermal power sets, the paper discusses how to calculate the exhaust steam enthalpy of steam turbines by utilizing the entropy escalation theory, the temperature entropy chart, the thermal element matrix analyzing method and the theory of equivalent heat drop; herewith realizing on line calculation of the exhaust steam enthalpy of steam turbines by the supervision system of thermal power sets and thus providing data for real time analyses of the efficiencies.
