The embodiments of the invention provide a power distribution network line fault recovery method. The method comprises the following steps that: if it is detected that a power distribution network line breaks down, the fault data of a power failure area are obtained according to a fault position; and corresponding power supply recovery processing is performed on the power failure load of the powerfailure area according to the state of a distributed power source, the state of a microgrid and the fault data in the power failure area. According to the power distribution network line fault recovery method provided by the embodiments of the invention, by means of the unified management of the distributed power source, the microgrid and a power distribution network feeder line, power supply recovery processing is carried out on the power failure load of the power failure area when the power distribution network line breaks down, and the power utilization requirement of the power failure load of the power failure area is met. Because the microgrid and the distributed power source have the characteristics of cleanness, high efficiency and flexible regulation, the power supply of the powerfailure load in the power failure area can be quickly and effectively recovered, and the stability and reliability of the operation of a whole power system are ensured.
