The method of one kind of network topology layout with

The present invention provides a method of patterning distribution network topology, each node acquires location data of the power system, the topology information between interconnected nodes, inter-node information line hardware parameters, selected from the nearest grid node as an initial master node; real-time each node acquires field distribution grid switching state of the switch, power parameters, phase fault, ground fault and a voltage and current at fault parameter information; using breadth first search stage extraction topological relationship between nodes; with a second stage determining the breadth of each node search method apparatus of the type: method using breadth first search traversal search apparatus determines the type of each node ID and layout; determining the distance between two adjacent nodes of each node in the topology of the lateral distance with respect to a parent node and the longitudinal distance, and displays the layout topology. The present invention employs longitudinal symmetrical layout method and a method of longitudinal stretching cabling, with the removal of the current network topology in FIG duplicate nodes, a distribution network topology layout.
