The invention discloses an intelligent suppression method for over-vibration of a tower drum of a large-scale wind generating set. The method comprises the steps that 1, data related to over-vibration of the tower drum of the wind generating set are acquired through a data acquisition device; 2, the data of the wind generating set in the step 1 are analyzed through a machine learning method, and related characteristic data and variables causing over-vibration of the tower drum of the wind generating set are obtained; 3, on the basis of the related characteristic data and variables in the step 2, an intelligent suppression algorithm model for over-vibration of the tower drum of the wind generating set and related calculation logic are obtained; 4, a potential over-vibration shutdown risk of the wind generating set is found in advance through the algorithm model and the related calculation logic in the step 3, an intelligent suppression action is carried out, and capacity reduction operation is carried out; and
