The invention relates to a low-voltage power distribution network topology generation and fault prediction method considering state perception, and the method is technically characterized in that a low-voltage power distribution network topology structure is generated based on a power distribution network low-voltage perception unit and through employing a low-voltage power distribution network topology adaptive generation method; establishing a low-voltage distribution network equipment fault prediction model according to the historical data and the monitoring data; and according to the generated topological structure and the established low-voltage power distribution network equipment fault rate model, power distribution network fault power failure economic risk loss is calculated based on the fault rate of each piece of equipment, and an active first-aid repair strategy of the low-voltage power distribution network is formulated. According to the invention, a transformer area topology layering automatic ge
