PROBLEM TO BE SOLVED: To provide a test procedure and a calculation method, approximating the efficiency of intermediate pressure section of a steam turbine while accurately accounting for an cooling effect of internal leakage. SOLUTION: In certain embodiments, this system includes a physical computing device having a tangible machine-readable medium including code. The code is adapted to determine the efficiency of the section of the steam turbine (22) based on a relationship between enthalpy difference values and leakage flow rate values between adjacent sections of the steam turbine (22). The relationship includes a point of equalizing an enthalpy of the leakage and an enthalpy at a destination of the leakage. COPYRIGHT: (C)2011,JPO&INPIT |
