Abstract

The invention discloses a man-machine interaction and management method and system for power distribution system fault self-healing, and relates to the technical field of power distribution system fault self-healing, and the method comprises the steps: collecting the information of a power distribution system, and judging the fault condition through the comprehensive evaluation of the fault degree of the power distribution system; performing grid structure optimization on the fault power distribution system, and performing load transfer capacity optimization on the power distribution system in a load cutting mode; through protection configuration and man-machine interaction, grading protection is carried out on different fault conditions, and power distribution system fault self-healing comprehensive evaluation is carried out. According to the method, the fault condition is judged by comprehensively evaluating the fault degree of the power distribution system, and the comprehensiveness of the feedback content of the power distribution system is improved; invalid contact is removed from a fault power distribution system, effective contact is reserved, and a standard single-ring network structure is created, so that the reliability of fault judgment and the efficiency of fault self-healing are improved; through graded protection, large-range power failure or excessive reaction is avoided, and the fault self-healing efficiency and stability of the power distribution system are improved.
