Problems solved by technology

However, there are many disadvantages in these two methods: 1) Adopting the two-meter method is undoubtedly the best measure to detect the user's electricity theft, but installing a bidirectional current meter undoubtedly increases the hardware investment of the meter, and this part of the investment is relatively large After all, electricity-stealing users are relatively few compared with non-stealing users, and the double-meter method increases the investment in the power system; There are errors in the topological relationship of household meters, the inaccurate calculation of low-voltage line losses, and meter measurement errors, etc., resulting in inaccurate judgments on electricity theft

Embodiment 1

[0027] This embodiment discloses an anti-stealing method, which can monitor the currently commonly used single-phase fee-controlled smart meters or users who have installed signal collectors. figure 1 As shown, the method includes the following steps:

[0028] S1. Receive the real-time voltage information reported by the user electric meter to be detected;

[0029] S2, judging whether the voltage of the user's electric meter to be detected has dropped, if it drops, then enter step S3, otherwise return to step S1;

[0030] S3. Calculate the percentage of voltage drop of the user's electric meter to be detected;

[0031] S4, judging whether the percentage of the voltage drop of the user electric meter to be detected is greater than the preset percentage threshold, if yes, enter step S5, otherwise return to step S1;

[0032] S5. Obtain the voltage of the user's ammeter within the same topology; in this step, the user's ammeter voltage can be obtained through the sampling APP pr...

Embodiment 2

[0035] This embodiment discloses an anti-stealing method, which can monitor the currently commonly used single-phase fee-controlled smart meters or users who have installed signal collectors. figure 2 As shown, the method includes the following steps:

[0036] S1. Receive the current information I sent by the master meter in real time 总 ;

[0037] S2, receive the current information I sent in real time by the n submeters connected to the master meter 1 , I 2 , I 3 ,..., I n , n is greater than or equal to 0; where n represents the number of the sub-table.

[0038] S3, calculate the sum of the real-time currents sent by n said sub-meters and the real-time current information I sent by said master meter 总 difference d 1 ; The specific calculation formula is: d 1 =I 1 +I 2 +I 3 +···, +I n -I 总 .

[0039] S4, judging the difference d 1 Whether it is greater than the preset first difference threshold, and if it is greater, an electricity stealing alarm signal is iss...

Abstract

The invention discloses an electricity larceny prevention method. Voltage information which is reported by user electric meters in real time can be utilized, whether the voltages of the user electricmeters are reduced or not is detected, the voltages of the user electric meters are compared with the voltages of the user electric meters in the topological relation, and the situation that an electricity larceny behavior exists can be determined if the voltage of only one meter is reduced or is zero and the voltages of other meters are not reduced. Meanwhile, current information which is reported by the user electric meters in real time can be utilized, and whether a user who steals electricity exists or not is judged by detecting the difference between the total current of branches of a transformer area and the current of all the user electric meters in the topological relation. If the difference is equal to a certain proportion of the branch total current, the proportion is a preset numerical value, an electricity larceny alarm signal is sent out, the situation that the user who steals electricity exists is determined, and the specific branch meter with the electricity larceny behavior can be judged by analyzing the current of each user electric meter. According to the electricity larceny prevention method, electricity larceny prevention monitoring can be carried out on the users on the basis that no facility is added, the cost is saved, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of power consumption management, in particular to a method for preventing power theft. Background technique [0002] The modern society is built in an energy system based on electricity. It is of great significance to ensure the power supply guarantee of power companies to ensure economic development and the production and life of residents. Measures such as strengthening the transformation of power supply and distribution lines and adopting larger-capacity electric energy meters have greatly ensured the safety of residents' electricity consumption. However, in the power supply operation of electric power companies, it is found that the act of stealing and stealing electricity still occurs from time to time, which seriously damages the economic benefits of power supply companies and also has a serious impact on the safety of power supply equipment. With the improvement of the means of stealing and stealing ...
