Station area identification method based on wireless communication acquisition

Abstract

The invention discloses a station area identification method based on wireless communication acquisition; and the method comprises the following steps: S1, collecting the electric quantity data of each node electric meter and the total electric quantity data of a total meter in a target station area in real time; S2, judging whether a difference value exists between the sum of the electric quantity data of each node electric meter and the total electric quantity data in a specified time period, and if Yes, judging that an error division electric meter exists in the target station area or an electric meter which is mistakenly divided into other station area exists, and transferring to execute step S3; S3, according to the variation trend of the difference value in the specified time period,identifying the mistakenly- divided target electric meter in the target station area or the electric meter which is mistakenly divided into other station area. The wireless communication data acquisition mode can realize automatic identification of the station area, and the station area identification method has the advantages of being simple, low in required cost, free of additional hardware equipment, high in identification efficiency and precision, and the like.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a method for identifying station areas based on wireless communication acquisition in a wireless communication mode. Background technique [0002] In order to install the low-voltage centralized reading system and count the line loss of the station area during power consumption management, it is necessary to determine which distribution transformer station a certain metering device belongs to, and in order to improve the utilization rate of the distribution transformer, it is necessary to move some users with relatively heavy loads to the user comparison To balance the three-phase power supply, it is necessary to judge the phase of the user. [0003] Such as figure 1 As shown, due to the complex interweaving of the lines in the station area and the irregular distribution of the user's electric meters, there will be two or more transformers in the station area toge...

Problems solved by technology

[0003] like figure 1 As shown, due to the complex interweaving of the lines in the station area and the irregular distribution of the user's electric meters, there will be two or more transformers in the station area together or nearby, etc., so the workload of the file recruiting personnel is heavy, and only by manual recording of the smart meter The ownership of the station area can easily lead to errors in the production of files. For example, it is very easy to make some nodes in the station area 1 (the nodes shown in the circles in the figure) into the file of the station area 2, so that the total power obtained by the station area 2 is Untrue total electricity, resulting in the failure of accurate and reasonable implementation of power management personnel's management and planning of power consumption

[0004] At present, the distribution area is usually separated by manual power outage and line inspection one by one, which is time-consuming and laborious and will cause inconvenience to users.

Some practitioners have proposed the method of automatically identifying the station area to realize the automatic identification of the station area, but it is usually realized by installing a carrier generator, and the power line sends to each terminal device in the station area every preset time, including the station area number to which the terminal device belongs and the carrier signal of the phase sequence code, so that each power line carrier terminal equipment receives the carrier signal, and obtains the station area number and phase sequence code contained in the carrier signal, thereby determining the station area and phase sequence of each power line carrier terminal equipment; this type of method The implementation is complicated, and a carrier generator must be added, which will increase the hardware cost, and it can only be applied to devices equipped with power line carrier terminals, and cannot be used for terminal devices using wireless communication modes
