The technical scheme of the invention is as follows: the invention discloses a multi-user repair fault positioning method based on low-voltage distribution network topology, which comprises the following steps of:
repair user positioning: acquiring fault repair acceptance information of a plurality of users within current 10 minutes from a customer service system of a power supply enterprise, and searching and positioning a node where each user is located in a low-voltage distribution network topology model according to a user number provided by a repair user;
tracing a low-voltage power supply path: searching connection nodes step by step upstream in a low-voltage distribution network topology model by taking repair reporting users as starting points until the distribution transformer is traced back to stop, and respectively summarizing the node equipment traced back by a plurality of users into respective low-voltage power supply paths;
thirdly, positioning hierarchical fault equipment: according to the topological hierarchy of the low-voltage distribution network, comparing whether public node equipment exists on power supply paths of a plurality of repair users, and if yes, entering the step A; if not, entering the step B:
A. from distribution transformer downward hierarchical analysis location trouble equipment and location one by one, specifically include:
i, checking whether the common node equipment is a distribution transformer or not, and if so, positioning the distribution transformer as fault equipment; if not, entering a step II;
