Recognition method of station area topology based on characteristic current information of key nodes in station area

Abstract

The invention discloses a station area topology identification method based on the characteristic current information of key nodes of the station area, and belongs to the technical field of station area equipment identification. The station area topology identification method based on the characteristic current information of key nodes in the station area of ​​the present invention comprises the following steps: the first step is to collect the topology identification records reported by each device by using the master station of the power consumption information collection system; the second step is to list The level of each device in the table is clarified; this process is synchronized with the establishment of the table; the third step is to confirm the direct upper-level equipment of each level of equipment in accordance with the order of levels from top to bottom; the fourth step is to Based on the analysis results of the three steps, the core topology diagram is drawn; the fifth step is to improve the relationship between the electric meters. The invention can realize the relationship identification of "change-line-box-meter" inside the high-quality station area, further consolidate the management foundation of the terminal link of power supply and consumption on the client side, and improve the line loss management, power outage emergency repair, and customer service capabilities of the station area.

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
