| description | The invention provides fault and service life prediction methods and devices for a wind generating set, and the fault prediction method comprises the steps: obtaining the operation duration and working condition data of the wind generating set at different moments, and enabling the working condition data to comprise at least one type; and according to the operation duration, the working condition data and a Weibull proportional risk model, predicting the cumulative failure probability of the wind generating set, wherein the size of a shape parameter in the Weibull proportional risk model is in positive correlation with the size of the at least one working condition data. When the fault of the wind generating set is predicted, at least one kind of working condition data of the wind generating set is used as the influence factor of the shape parameter in the Weibull proportional risk model, and the multi-level Weibull proportional risk model is established, so that the prediction precision of the model is impro |
