The present invention discloses a power distribution network fault early warning method aiming at multiple factors. The method comprises the following steps: 1) collecting the operation work condition of a power distribution network monitoring device faults, device health states and the environmental factors where the device is located; 2) selecting influence factors according to the simultaneous and mutually exclusive principle, and setting the weight of each influence factor in the formation of the device fault; 3) calculating the total points of the influence factors of the device, and determining the possibility of the fault happening of the device; and 4) performing fault early warning with the corresponding grades according to the result of the step 3). The power distribution network fault early warning method aiming at the multiple factors performs quantization of the operation condition of the power distribution network device and performs early warning of the impending possible faults of the power distribution network so as to provide an auxiliary decision support means for the lean management of the power distribution network.
