Transformer area topology identification method based on characteristic current information of key nodes of transformer area

Abstract

The invention discloses a transformer area topology identification method based on characteristic current information of key nodes of a transformer area, and belongs to the technical field of transformer area equipment identification. The transformer area topology identification method based on characteristic current information of the key nodes of the transformer area comprises the following steps: 1, collecting topology identification records reported by each device by using a master station of an electricity utilization information acquisition system; 2, determining the hierarchy of each device in the table while establishing the table; 3, according to the level sequence from top to bottom, carrying out direct upper-level equipment confirmation work of each level of equipment; 4, drawing a core topological structure diagram according to an analysis result of the step 3; and 5, perfecting the relation of the electricity meters. The transformation-line-box-table relation identification in the high-quality transformer area can be realized, the management basis of the client-side power supply and consumption terminal link is further tamped, and the line loss management, power failure repair and client service capabilities of the transformer area are improved.

Description

technical field [0001] The invention relates to a station area topology identification method based on characteristic current information of key nodes in the station area, and belongs to the technical field of station area equipment identification. Background technique [0002] The traditional station area generally does not install monitoring equipment at the meter box and the branch box of the station area, and basically does not have the ability to recognize the topology of the entire link of the station area. In the maintenance work of the traditional low-voltage station topological relationship, it is mainly through the staff to find the line on site: find the transformer according to the live line in the meter box, and determine the corresponding name and number of the station according to the nameplate of the transformer; if there are many underground cables Or if the wiring of the overhead line is messy and there are many shelters, it is necessary for the on-site per...

In the maintenance work of the traditional low-voltage station topological relationship, it is mainly through the staff to find the line on site: find the transformer according to the live line in the meter box, and determine the corresponding station name and number according to the nameplate of the transformer; if there are many underground cables Or if the wiring of the overhead line is messy and there are many shelters, it is necessary for the on-site personnel to record the structure of the station area by means of closing the gate for observation and manual drawing. Municipal power consumption has a lot of impact, and unified digital storage cannot be realized
