Power distribution network line fault prediction method and device, equipment and storage medium

The invention discloses a power distribution network line fault prediction method and device, equipment and a storage medium. The method comprises the following steps: acquiring a target type corresponding to a tree barrier under a target line, each piece of historical state information corresponding to the target line and a target tower height; inputting the target type and the prediction duration into a target tree height growth model for tree height prediction to obtain a target tree height; determining each first sag length corresponding to the target line based on the historical state information, and averaging each first sag length to obtain a second sag length; inputting the second sag length, each first sag length and the prediction duration into a length prediction model for length prediction to obtain a target sag length; and determining a fault prediction result corresponding to the target line based on the target tower height, the target tree height and the target sag length, thereby realizing lin
