The invention relates to the technical field of distribution network repair, in particular to a distribution network repair assistant decision-making and intelligent management and control system, which comprises a data acquisition module, a data storage module, a fault study and judgment and diagnosis module, a repair dispatching module, and a repair dynamic visualization module. In view of information interaction and integration, the problems of fast and accurate fault positioning, repair resource dispatching optimization and the like can be solved; resources in all aspects are called thoroughly to study distribution network fault intelligent search and positioning, fault repair and recovery technologies, the fault repair time is reasonably arranged, a fault repair strategy and a scheme are scientifically formulated, the fault repair efficiency is improved, the fault repair cost is effectively reduced, a health fault repair comprehensive management system can be established conveniently, and the basic management level of power grid repair and operation are thus improved.
