Method and device for acquiring importance scores of power distribution network line rejump influence factors

The invention relates to the technical field of power grid equipment manufacturing, in particular to a method and device for obtaining importance scores of power distribution network line rejump influence factors. The method comprises the following steps: S1, constructing a power distribution network frame topological graph according to a power distribution network ledger and connection relationship data; S2, based on the power distribution network system, enabling a meteorological monitoring system to extract power failure data of a power failure event; S3, constructing a corresponding relation based on the power failure data and a power distribution network frame topological graph; S4, preprocessing the power failure data, and obtaining a characteristic value according to influence factors of a power failure event; S5, based on the characteristic values, constructing a random forest regression prediction model, and obtaining a future power failure event probability; and S6, calculating to obtain the importa
