The invention discloses a power distribution network system fault self-healing implementation management and control system, and belongs to the technical field of power distribution network self-healing. By constructing a network association and topology matrix, fault positioning and isolation can be timely and efficiently realized, the stability of the voltage of the power distribution network under the fault is recovered by adopting a load shedding measure, and the actual power generation load difference is compensated by utilizing a node voltage lifting strategy; through emergency load compensation with high capacity and load margin with balanced distribution, the stability of load operation of the power grid can be guaranteed; the implementation of the self-healing control scheme can achieve the purpose of self-healing control of the voltage of the power distribution network under the condition of small load margin loss, and can effectively maintain the stability of the operation of the power grid.
