Abstract

The invention provides a power distribution network topology layout method. The method comprises the step of obtaining geographical position data of nodes of an electric power system, the topology information of connection of the nodes and line hardware parameter information among the nodes and selecting the node closest to a power transmission network as an original female node, the step of obtaining the on-off state, power parameters, interphase faults and grounding faults of spot switches of the nodes of the power transmission network and the voltage and current parameter information of the spot switches when the faults happen, the step of extracting the topology relation among the nodes through a first-level breadth-first search method, the step of determining the types of devices of the nodes through a second-level breadth-first search method, the step of traversing, searching for and determining the types of the devices of the nodes through the breadth-first search methods to carry out layout numbering, and the step of determining the distance between every two adjacent nodes on a topology graph and the transverse distance and the longitudinal distance of the nodes relative to the female node and carrying out the topology layout and display. The repeated nodes in the current power transmission network topology graph are removed through a longitudinal symmetrical layout method and a longitudinal draw type wiring method, and the power transmission network topology layout is carried out.

Description

technical field [0001] The invention belongs to the technical field of distribution network, and in particular relates to a distribution network topology layout method. Background technique [0002] With the progress of my country's socialist construction, the demand for electricity in all walks of life is increasing day by day, especially in areas with rapid economic development, the industrial and civil loads are rising rapidly, and the number of power distribution systems and power distribution equipment has increased significantly. The network structure of the power system is becoming more and more complex, and the operation mode of power supply is changing more and more frequently. There are higher and higher requirements for the stability of distribution network operation, the effectiveness of regulation, and the reliability of monitoring information. Therefore, the collection, storage and analysis of real-time monitoring information of the distribution network has beco...
