The invention discloses a low-voltage distribution network project feasibility study and review system and method. The low-voltage distribution network project feasibility study and review system comprises a transformer position determination module which is used for obtaining the onsite investigation data of an area with unreasonable distribution points, calculating the power supply radius and the capacity per household after transformation, and determining the number and position of transformers, a training plan publishing module which is used for acquiring early-stage planned high-voltage distribution network project data, drawing a training plan table and distributing the data to corresponding subordinate department users, a subordinate department receiving module which is used for receiving the training schedule and popping up a training notification, a lower-level department module for uploading the searchable materials for collecting and storing the searchable data of each low-voltage power distribution network project uploaded by the lower-level department, and a researchable data secondary internal review module which is used for obtaining researchable data of each low-voltage distribution network project, comparing the researchable data with the researchable review opinion template of the medium-low voltage distribution network project to obtain data lacking of the researchable data of the low-voltage distribution network project, and modifying and adjusting the researchable data of the low-voltage distribution network project.
