Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Please refer to figure 1 , which shows the architecture diagram of the power transmission network involved in the present invention. The power transmission network includes the following grid equipment: a coordinating equipment 110 , a voltage pulse transmitter 120 and at least one station equipment 130 .

[0039]The coordinating device 110 may be a concentrator in a station installed on the transformer side in the station. Alternatively, the coordinating device 110 may also be a central coordinator (Central Coordinator, CCO) set in the concentrator.

[0040] The voltage pulse transmitter 120 is also installed on the side of the transformer in the station area, and is used to transmit a voltage pulse signal to the power transm...

Abstract

The invention discloses a method for identifying electricity meters in a transformer area of an electrical power system, which belongs to the technical field of power line communication. The method comprises the following steps that: a coordination unit controls a voltage pulse transmitter to send a voltage pulse signal carrying a transformer area mark of a transformer area where the coordination unit is located to a subordinate power transmission network of the transformer area and queries identification marks separately acquired by each station unit from the voltage pulse signal in the power transmission network in a power line carrier communication manner; the transformer area mark of the transformer area is compared with the identification marks fed back by the station units so as to determine whether the station units are in the transformer area; and if the station units are in the transformer area, electricity meters corresponding to the station units are determined to be in the transformer area, and a power grid maintainer does not need to hold the voltage pulse transmitter to receive and detect voltage pulses of electricity meters one by one. Thus, manual operation steps are simplified, and identification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power line communication, in particular to a device and method for determining electric meters in a power system station area. Background technique [0002] With the popularization of smart grids, services such as accurate collection of electric energy information, line loss calculation, and load statistics of a station area (that is, a power supply area of ​​a transformer) all need to accurately identify the electricity meters contained in a station area. [0003] In the prior art, when identifying the electric meters contained in a station area, a voltage pulse transmitter is used to transmit a voltage pulse signal to the power transmission network under the station area, and the grid maintenance personnel use a hand-held voltage pulse receiver to control each electric meter The voltage pulse is received and detected at the station, and when the voltage pulse signal sent by the voltage pulse transmitter...
