Problems solved by technology

[0004] The above-mentioned anti-stealing measures are all anti-stealing technologies for components. Most of them are tricks. Although some electricity theft phenomena can be identified, they are not universally applicable and network-wide, and cannot be fully and accurately identified. Electricity theft; and when there is electricity theft, the actual power consumption cannot be accurately calculated, which may easily cause conflicts between the power management department and the electricity theft users

Embodiment 1

[0044] figure 1 A structural block diagram of the anti-stealing system provided by this embodiment is shown. Such as figure 1 As shown, the anti-stealing system includes a monitoring center 30 , a first detection device 10 arranged in the watt-hour meter 1 and a second detection device 20 arranged between the transformer 2 and the watt-hour meter 1 . A power supply line corresponding to each first detection device 10 is provided with a second detection device 20 , and the second detection device 20 has the same address code as the first detection device 10 disposed on the same power supply line.

[0045] The first detection device 10 is used to transmit the voltage data and current data of the power supply line measured by the watt-hour meter 1 to the monitoring center 30 .

[0046] The second detection device 20 is used to collect current data on the low-voltage cable of the power supply line, and transmit the collected current data to the monitoring center 30 .

Embodiment 2

[0068] figure 2 A structural block diagram of the anti-stealing system provided by this embodiment is shown. Such as figure 2 As shown, on the basis of the above-mentioned first embodiment, the electricity theft prevention system adds a monitoring terminal 40 for receiving the electricity theft alarm signal sent by the monitoring center 30 . The monitoring terminal 40 here includes a mobile communication terminal. That is to say, when the monitoring center detects electricity theft, it can determine the administrator in the area where the meter is located according to the address code of the stolen meter, and will carry the address of the stolen meter. The coded electricity tampering alarm signal is sent to the administrator's mobile phone, so that the administrator can deal with it in time.

[0069] In this embodiment, the alarm module of the monitoring center may only be equipped with a remote communication alarm unit, or may be equipped with the above-mentioned signal ...

Embodiment 3

[0071] This embodiment provides an anti-stealing method, which is applied to the monitoring center in the first or second embodiment above. Figure 4 A flow chart of the method is shown, as Figure 4 As shown, the method includes:

[0072] Step S401, receiving data transmitted by the first detection device and the second detection device;

[0073] Step S402, comparing the voltage data transmitted by the first detection device with the preset reference voltage, if the two are not consistent, it is determined that there is electricity stealing phenomenon; compare the first detection device and the second detection device with the same address code Whether the current data is consistent; if not, it is judged that there is electricity stealing;

[0074] Step S403, when it is determined that there is electricity theft phenomenon, send out an electricity theft alarm signal;

[0075] Step S404, calculating the actual power consumption according to the current data transmitted by t...

Abstract

The invention provides an electricity-stealing-preventing system and method, and belongs to the technical field of electric-power-system electricity stealing preventing. The electricity-stealing-preventing system comprises a monitoring center, first detection devices arranged in electricity meters and second detection devices arranged between transformers and the electricity meters; the second detection devices are arranged on power supply lines corresponding to all the first detection devices; the second detection devices and the first detection devices arranged on the same power supply lines have same address coding. According to the electricity-stealing-preventing system and method in the embodiment, the first detection devices and the second detection devices which are correspondingly arranged on the same power supply lines are adopted, power data of electricity meter ends and power data of transformer ends are measured respectively, the results are compared in the monitoring center, and all kinds of electricity stealing behaviors can be fully and accurately identified. When it is detected that the electricity-stealing phenomenon occurs, the actual electricity consumption amount can be accurately calculated according to the sampling values of the second detection devices.

Description

technical field [0001] The invention relates to the technical field of electric power system anti-theft technology, in particular to an anti-electricity theft system and an anti-electricity theft method. Background technique [0002] As the country's secondary energy, electric energy is closely related to social and economic development and people's lives. Electricity theft is for the purpose of illegal possession of electricity consumption, underpayment or non-payment of electricity bills, artificially using concealment or other means to make meters not measure or undercount electricity consumption. There are various forms of stealing electricity. Common stealing methods include under-voltage stealing, under-current stealing, phase-shifting stealing, differential expansion stealing, and meterless stealing. In recent years, with the development of science and technology, there have been more and more methods of stealing electricity, and they have become more and more hidden...
