Topology identification system and identification method thereof

Abstract

The invention provides a topology identification system and an identification method thereof. The topology identification system comprises a plurality of identification hosts and a plurality of identification slaves, the identification hosts are installed at a near load side of a detected topology, and the identification slaves are installed on each line of a near power supply side of the detected topology. The identification system also comprises a cloud platform which is in communication connection with the identification hosts and the identification slaves. The identification hosts input the high-frequency current at the near-load side of the detected topology and sends a first current signal about the high-frequency current to the cloud platform; and the identification slaves are fixed at the near power supply side through the open mutual inductor calipers, monitor the high-frequency current in the line, convert the monitored high-frequency current into a second current signal and send the second current signal to the cloud platform, and the cloud platform compares the first current signal with the second current signal and outputs an identification result. According to the topology identification system and the identification method thereof provided by the invention, the topology of a power distribution network can be automatically and quickly identified without power failure, and the identification efficiency of the power distribution network is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power grid topology data management, in particular to a topology identification system and an identification method thereof. Background technique [0002] In recent years, the continuous improvement of people's living standards has directly promoted the increase in the load of power users, resulting in frequent changes and adjustments (such as relocation, expansion, cutover, distribution, etc.) of power facilities within users and in the station area. The corresponding relationship of the grid lines became confused, which was seriously inconsistent with the drawings of the design archives. [0003] This phenomenon brings great inconvenience to the operation and management of the distribution network, and at the same time poses a threat to the safety of electricity consumption of users. In terms of identifying the topology of the station area, domestic and foreign scholars have done a lot of research, mai...
