The present invention relates to a method to evaluate aging of a low-pressure turbine. According to an embodiment of the present invention, a method to evaluate aging of a low-pressure turbine may include the steps of: extracting information with respect to an operation of a low-pressure turbine using a sensor located on a turbine unit; a step of calculating at least one among the pressure ratio, the flow coefficient, and the efficiency of the low-pressure turbine as an aging index using the operation information; and using regression analysis with respect to the aging index to determine the extent of aging of the low-pressure turbine. |
