Embodiment 1

[0046] Embodiment 1 of the present invention provides a method for identifying low-voltage distribution stations, the specific flow chart is as follows figure 1 shown, including:

[0047]S101: Search for station area concentrators adjacent to each station area concentrator, and establish a pairwise proximity relationship;

[0048] S102: Determine the gray list users of each station concentrator based on the white list users of each station concentrator with a close relationship;

[0049] S103: Determine the station concentrator to which each graylist user belongs according to the number of users establishing communication with each graylist user, and set the graylist user as a whitelist user of the station concentrator to which the graylist user belongs.

[0050] Each of the station concentrators searches for station concentrators adjacent to the station concentrator, and establishes a two-by-two proximity relationship, including:

[0051] The concentrators of each station r...

Embodiment 2

[0072] Based on the same inventive concept, Embodiment 2 of the present invention also provides a low-voltage distribution station area identification system. The structure diagram of the low-voltage distribution station area is as follows image 3 as shown, image 3 Among them, the two station areas A and B of a total of 10kV feeders are adjacent station areas. There are A1, A2, A3...An total of N user smart meters within the jurisdiction of the concentrator in station A, and B1 is under the jurisdiction of the concentrator in station B. , B2, B3...Bm total M user smart meters. Due to the crosstalk characteristics of PLC signals across platforms, the user smart meter A1 in station A is registered in the concentrator in station B through PLC cross-region communication; similarly, the user smart meter B1 in station B communicates through cross-region PLC Registered to the A station concentrator. The white list formed by the concentrators in station A and station B may contain...

Abstract

The invention provides a low-voltage distribution area identification method and system, and the method comprises the steps: searching an area concentrator adjacent to each area concentrator, and building the pairwise adjacent relation; determining a grey list user of each transformer area concentrator based on the white list user of each transformer area concentrator with the proximity relation;determining a transformer area concentrator to which each grey list user belongs according to the number of users establishing communication with each grey list user; and setting the grey list user asa white list user of a transformer area concentrator to which the grey list user belongs, wherein the user side does not need to install a sending device, so that identification cost is greatly reduced, the safety is improved, a corresponding user number is obtained through the A transformer area user grey list and the B transformer area user grey list; the method and the system greatly improve the recognition efficiency and recognition accuracy, enable each user in the user grey list to sequentially communicate with all users in the user white list of the local district and the adjacent district based on the power line carrier, solve a problem of user judgment in the user grey list, are simple and easy to implement, and save the time cost and labor cost.

Description

technical field [0001] The invention relates to the technical field of electric power automation, in particular to a method and system for identifying low-voltage distribution stations. Background technique [0002] With the rapid development of the power grid, the number of power users continues to grow, and the scale and structure of the low-voltage distribution network are becoming larger and more complex. The traditional extensive management model is difficult to adapt to the development of the times, and the lean management of distribution stations has become a trend. In the business management of the low-voltage distribution network, the power management department often needs to check user files to ensure that the files are accurate and provide correct management data for marketing management, including user file ownership, network topology, and user equipment power consumption. Phase and working phase sequence, etc. These data are the basic data to ensure the balanc...
