Problems solved by technology

[0003] At present, there are two ways to identify the topology without power failure in the station area: (1) small zero-crossing signal injection topology identification method, which requires external signal injection equipment; (2) impedance iterative calculation topology identification method, which needs to accumulate a large amount of electrical working condition data and iterative calculation It takes a long time, and the calculation accuracy is poor when the electrical distance is close; (3) the electricity data analysis method has a low topology recognition accuracy and poor adaptability to complex station areas; Normal power supply for users, suitable for power outage maintenance in station area or use in new station area

Abstract

The invention relates to a method for identifying and generating the topology of a station area based on the principle of route detection. The intelligent switch and the smart meter inject characteristic signals into the power line in different time periods, so that the edge IoT proxy device collects the detection results of all characteristic signals, and combines the station area Household change relationship, node type, phase and address information to judge the node level and connection relationship in the station area. The invention can dynamically identify and generate the topology of the station area by means of route detection, find out the actual inconsistency of the topology map of the station area in time, and realize the lean management of the station area.

Description

technical field [0001] The invention relates to the technical field of power detection, in particular to a method for identifying and generating station topology based on the principle of route detection. Background technique [0002] At present, the way to understand the topology relationship of the switches in the station area mainly depends on the construction drawings of the station area wiring. This requires manual input of topological files that match the map and actual during the initial construction of the station area. If the topology relationship changes due to the replacement of lines and equipment, it needs to be manually re-entered and updated. [0003] At present, there are two ways to identify the topology without power outage in the station area: (1) The zero-crossing point small signal injection topology identification method requires external signal injection equipment; (2) The impedance iterative calculation topology identification method needs to accumula...
