In one embodiment, a calculation method of moisture loss in a steam turbine calculates first a wetness fraction at the inlet and outlet of each of stationary blade cascades and rotor blade cascades. Subsequently, the moisture loss is classified into (1) supersaturation loss, (2) condensation loss, (3) acceleration loss, (4) braking loss, (5) capture loss and (6) pumping loss, and a loss for calculation of the moisture loss is selected from the above losses (1) to (6) according to the wetness fraction of steam at the inlet and outlet of each blade cascade. An amount of each selected loss is calculated, and an amount of moisture loss at each blade cascade is calculated. |
