This application relates to an intelligent linkage control method for power distribution switchgear. Each power distribution switchgear is configured with a linkage unit, and adjacent linkage units are connected via peer-to-peer communication links to form an autonomous collaborative domain. Each linkage unit sends topology description messages to each other to construct an adjacency topology table. When the topology changes, the linkage action criteria, including fault initiation settings and action timing differences, are recalculated and broadcast for verification within the domain. During a fault, each linkage unit collaboratively identifies the faulty section based on the combination relationship of the fault current direction. The linkage units at both ends of the faulty section are locally disconnected and isolated without requiring a master station command. When power is restored, the linkage unit corresponding to the tie switch confirms through distributed interlocking that the current closing will not form a closed loop before closing. This application enables the location, isolation, and restoration of power distribution faults to be autonomously and collaboratively completed by the surrounding equipment, shortening processing delays, adapting to dynamic topology changes, and avoiding restoration conflicts.
