The invention discloses a power distribution network multi-terminal section fault positioning method. The method comprises the steps of obtaining working parameters and a circuit topological structure of a target power distribution network; determining the topology type of the target power distribution network; and carrying out specific power distribution network multi-end section fault positioning according to the confirmed topology type of the target power distribution network. According to the power distribution network multi-terminal section fault positioning method provided by the invention, accurate positioning of the power distribution network multi-terminal section fault is realized through the voltage and current synchronization quantity measured by the synchronization quantity measuring device, the short circuit characteristic influence of the distributed power supply is not considered, the influence of transition resistance during the short circuit fault is avoided, the operation speed is high, and
