A method and system for self-healing faults in power distribution networks

Abstract

This invention discloses a method and system for self-healing faults in distribution network lines, comprising: S1: The distribution network system compares real-time acquired distribution network line data with standard distribution network line data stored in the distribution network system to determine whether the distribution network line is faulty; S2: If a fault is determined, the fault location is located; if the distribution network line is determined to be operating normally, the distribution network line data is stored; S3: The fault location is isolated, and then the distribution network line fault is restored. This invention simplifies the distribution network structure by dividing each node of the distribution network into several T-shaped aggregate nodes, and inspecting each node within the T-shaped aggregate nodes to accurately locate the fault location; then, the power supply priority value of each feeder is calculated sequentially, sorted from largest to smallest, and a suitable feeder is selected based on the total load of the area to be restored. The tie switch is closed, the voltage and current are verified, and a feasible power supply restoration plan is generated.
