The invention discloses a network topology identification system for a power distribution area, relates to the technical field of power distribution areas, and solves the problems that the judgment process of fault nodes is not comprehensive and misjudgment is easy to occur due to the fact that the influence conditions of peripheral nodes are not considered. Marking the determined abnormal nodes in a power topological graph; performing time period analysis on the interconnected abnormal nodes, judging whether the abnormal nodes are continuous abnormal nodes or not, and determining whether the abnormal nodes are in a fault state or not by adopting a parameter adjustment mode aiming at a single group of abnormal nodes; for continuous abnormal nodes or an abnormal node set, different parameter adjustment analysis modes are adopted to determine the corresponding abnormal nodes, the corresponding fault nodes can be rapidly determined by adopting the identification processing mode, the determination mode is higher
