Zusammenfassung:The invention provides a fault detection method for a water turbine, which comprises the following steps: acquiring the initial degradation grade of a water turbine component in each detection item, determining the influence factor of each water turbine component relative to the water turbine according to the initial degradation grade, and determining the fault of each water turbine component according to the initial degradation grade and the influence factor of each water turbine component. The method comprises the following steps: respectively determining a single degradation score of each water turbine component, determining a total degradation score of the water turbine component according to the single degradation score of each water turbine component, and determining a fault evaluation state of the water turbine component according to the single degradation score and/or the total degradation score. According to the method, the fault evaluation state of the water turbine can be accurately determined base
