The invention relates to a power distribution system remote maintenance method based on the IEC61850 standard, and belongs to the technical field of power systems and automation thereof. The method comprises the following steps: (1) a power distribution master station in a power distribution system sends Discover information; (2) the power distribution system acquires configuration information of a power distribution terminal; (3) the power distribution master station obtains real-time measurement data of the power distribution terminal; and (4) a power distribution station generates a measurement point table for the power distribution terminal according to the real-time measurement data of the power distribution terminal. By adopting the method, power distribution network terminal accessing and exiting is realized, the process is full-automatic, and no manual check on a data point table is needed. By adopting the method, a power distribution network terminal can be automatically discovered and registered. The primary topology of a power distribution network is updated automatically when a power distribution terminal logs off a system or fails. Especially, after the power distribution terminal logs off a system or is subject to permanent failure, the system automatically logs the terminal out in time. Thus, real-time updating of the distribution network topology is realized, and accurate information is provided for the relay protection function.
