Abstract

The purpose of the present invention is to provide: a water quality diagnostic system in which degrees of water quality abnormality can be diagnosed more accurately and more uniformly; a power generation plant; and a water quality diagnostic method. This water quality diagnostic system disposed in a power generation plant is provided with: an electric conductivity measurement unit (3) that is disposed in a water circulation line (1) of a power generation plant and measures the electric conductivities of circulating water; a pH measurement unit (4) that is disposed in the water circulation line (1) and measures pH values of the circulating water; and a control device (5) that diagnoses degrees of water quality abnormality. The control device (5) is provided with: a storage unit that stores reference values based on correlations between the pH values and the electric conductivities in the water circulation line (1), a plurality of preset ranks that indicate the degrees of water quality abnormality in the water circulation line (1), and a range of deviations from the reference values corresponding to the plurality of ranks; and a rank determination unit that determines the ranks of measurement results, on the basis of the measurement results by the electric conductivity measurement unit (3) and the pH measurement unit (4), and on the basis of the range of deviations stored in the storage unit.
