Abstract

The invention relates to the technical field of low-voltage distribution network line detection, in particular to a low-voltage transformer area physical topology online generating and real-time monitoring method. The method includes the steps that signal generating units, signal detecting units and a data transmitting unit are reasonably deployed on a transformer area line, and the data transmitting unit communicates with an electricity power monitoring platform; after a topology online generating instruction is sent, all branch line physical topologies are generated one by one and are combined into an integral low-voltage transformer area physical topology to be stored; the generated physical topology is compared with that stored before, and if the generated physical topology is different from that stored before, the change position is marked. The invention further provides a low-voltage transformer area physical topology online generating and real-time monitoring system. The signal generating units are arranged on equipment at the tail end and the middle of the transformer area line, the signal detecting units are arranged on equipment in the middle and the head end of the transformer area line, and the data transmitting unit is arranged at the low-voltage side of a distribution transformer. The transformer area line physical topology can be generated on line and monitored in real time, topology changes of the line are found in time, and reliable operation of an electric system is ensured.

Description

technical field [0001] The invention relates to the technical field of detection of low-voltage distribution network lines, in particular to a method and system for on-line generation and real-time monitoring of the physical topology of a low-voltage station area. Background technique [0002] In recent years, with the rapid development of the power grid, the hardware facilities in the distribution transformer area have been greatly improved. The marketization of the power system has put forward more refined management requirements for the power management department. The need to reduce consumption and loss is more urgent. It has become an important indicator to reduce the line loss rate of the station area and make the line loss rate of the station area meet the national standard. In line loss management, it is the most difficult to manage by station area and phase, mainly reflected in: [0003] 1. The basic information of the station area is incomplete; for some old stat...
