Abstract

The invention discloses a low-voltage power distribution network topology identification system based on pulse characteristic current signals. A bus current centralized controller is installed on a low-voltage incoming line switch layer, a plurality of branch current detectors are installed on the low-voltage outgoing line switch layer, a plurality of branch current detectors are installed on thebranch line switch layer, a plurality of branch current detectors are installed on the metering box user switch layer, and a pulse characteristic current generator is installed at the tail end of a user. On the premise that an original circuit is not changed, a bus current centralized controller is arranged at a main switch;, a branch current detector and a pulse characteristic current generator are respectively arranged on each branch and the power distribution network user tail end; and the topological structure of the low-voltage power distribution network is obtained, the change of the topological structure of the power distribution network can be monitored online in real time, the topological structure of the low-voltage power distribution network is monitored and reported in real time, and the power supply reliability and the power grid operation and maintenance management level are improved.

Description

technical field [0001] The patent of the present invention relates to a distribution network topology identification system, especially a low-voltage distribution network topology identification system based on pulse current characteristic signals. Background technique [0002] With the development of the pan-power Internet of Things and the continuous improvement of users' requirements for power quality, how to improve the power supply reliability and production management level of the distribution network has become a major problem facing the power industry. Realizing data sharing and comprehensive utilization between marketing and operation and maintenance business systems has become an effective way to solve this problem. The basic work is to establish the topological relationship between "distribution-line-household", improve the ledger information of low-voltage equipment, improve the degree of information sharing among various departments of the power company, and the...
