Abstract

The invention provides a method and a device for determining a topological relationship of power lines. The method comprises steps of sending measurement control information to radio nodes or receiving measurement data from the radio nodes, the radio points corresponding to the first and second positions of the power distribution network respectively; using a transmitting coupler set at the firstposition of the power distribution network to inject a topological relationship measurement signal into a power line, and using a receiving coupler located at the second location of the power distribution network to extract the topological relationship measurement signal from the power line; and using at least one of the measurement data of the topology relationship measurement signal and the power line interference measurement data reported by the radio points to determine the power line topology relationship. The method and the device can timely detect the change of the terminal load connection relationship of the power grid, improve the accuracy of the line load statistics and the line loss statistics, and have practicality.

Description

technical field [0001] The invention relates to the field of power network monitoring, in particular to a method and device for determining the topological relationship of power lines. Background technique [0002] The path loss of the power supply line of the power grid is a judgment factor for judging the performance of the power grid and finding the fault of the line. In the actual power supply site, because the power distribution network covering the same area or building power supply will include two or more tree-shaped power supply sub-networks that belong to different substation equipment and are adjacent in layout space, Each end user obtains power from specific substation equipment through its connected tree structure power supply subnetwork. In the process of power line maintenance, troubleshooting and power grid transformation, the power receiving channels of end users on these power supply sub-networks will change, and the corresponding power transformation equi...
