Zusammenfassung:	The invention provides a health evaluation method and device for a water-turbine generator set, and relates to the technical field of hydroelectric generation, and the method comprises the steps: obtaining an original data set; performing correlation calculation on the original data set to obtain a first processing data set; performing principal component analysis on the first processing data set to obtain a second processing data set; inputting the second processing data set into a preset time sequence prediction neural network to obtain component state parameters in the plurality of water-turbine generator sets; calculating the component state parameters in all the water-turbine generator sets through a preset evaluation model to obtain an evaluation information set; and calculating the evaluation information set through a preset arrangement model to obtain a health evaluation value of the water-turbine generator set. On one hand, the evaluation influence of relevance between different components on the who
