Power transmission line maintenance method and device, computer equipment and storage medium

The invention relates to the technical field of power transmission line maintenance, and discloses a power transmission line maintenance method and device, computer equipment and a storage medium, and the power transmission line maintenance method comprises the steps: determining a current maintenance plan result of a to-be-maintained power transmission line based on a main problem model of the to-be-maintained power transmission line; judging whether each sub-problem model returns a cut set to the main problem model or not based on a current maintenance plan result; and when each sub-problem model does not return to the cut set, outputting a current maintenance plan result as a final power transmission line maintenance plan. Through the implementation of the method, the uncertainty of new energy output prediction in future scenes is overcome, multiple scenes in the maintenance process are comprehensively considered, the safe and economic operation of a power grid is better guaranteed, the safety constraint s
