Embodiment 1

[0026] According to an embodiment of the present invention, a method for analyzing electricity theft is provided, such as figure 1 shown, including:

[0027] Step 10: Calculate the industry trend coefficient W of electricity consumption in a certain industry, and determine whether the electricity consumption of this industry has a characteristic trend: when W is greater than the first statistical threshold When it is considered that the electricity consumption of the industry has a characteristic trend, go to step 20;

[0028] Otherwise, there is no characteristic trend in the industry, and the process ends;

[0029] Step 20: When the electricity consumption of a certain industry in step 10 has a characteristic trend, calculate the coincidence coefficient S between the individual user in the industry and the industry characteristic trend, and determine whether the user's electricity consumption is consistent with the industry characteristic trend: when S greater than the se...

Embodiment 2

[0032] According to an embodiment of the present invention, a method for analyzing electricity theft is provided, such as figure 2 As shown, it is the specific process of step 10 in method embodiment 1, including:

[0033] Step 101: Obtain a number of electricity consumption data of a large number of users in a statistical period from the electricity consumption information collection system, and classify the obtained electricity consumption data according to different industries;

[0034] Step 102: According to the electricity consumption data of a certain industry, such as users of the catering industry, obtained in step 101, obtain the ranking of the electricity consumption of the catering industry at different observation points in a certain statistical period, thereby obtaining the electricity consumption trend of the catering industry;

[0035] Among them, the users may be dedicated users, industrial and commercial users, residential users, and the like. A long period ...

Embodiment 3

[0043] According to an embodiment of the present invention, a method for analyzing electricity theft is provided, such as image 3 As shown, it is the specific process of step 20 in method embodiment 1, including:

[0044] Step 201: Calculate the coincidence coefficient S of a single user and an industry characteristic trend according to the following formula,

[0045] S = 1 - 6 Σ i = 1 n d i 2 N ( N 2 - 1 ) ,

[0046] where d i is the difference between the ranking level of the industry characteristic trend and the s...

Abstract

The invention discloses an electricity theft analyzing method and system. The method includes calculating industry power consumption amount trend coefficient and judging whether the industry power consumption amount trend is greater than a first statistical threshold value or not; if the industry power consumption amount trend is greater than the first statistical threshold value, calculating the matching coefficient of a single user and the industry characteristic trend and judging whether the matching coefficient of the single user and the industry characteristic trend is greater than a second statistic threshold value or not. If the matching coefficient of the single user and the industry characteristic trend is greater than the second statistic threshold value, no electricity theft occurs; if the matching coefficient of the single user and the industry characteristic trend is not greater than a second statistic threshold value, electricity theft may occur. According to the invention, through studying current information of a power consumption information collecting system and through deep digging and effective use of mass data, industry power consumption trend and power consumption trend of users in the industry can be analyzed and the matching degree can be judged, so that whether electricity theft occurs or not can be judged. Therefore, effectiveness and pointedness of the collection system in aspects of electricity theft prevention and investigation are improved.

Description

technical field [0001] The invention relates to the technical field of electricity consumption, in particular, to a method and system for analyzing electricity theft. Background technique [0002] Electricity user electricity consumption information collection system is a system for collecting, processing and real-time monitoring of electricity consumption information of electric power users. , distributed energy monitoring, information interaction of intelligent electrical equipment and other functional simulation design. [0003] At present, most network companies have installed electricity consumption information collection systems, and integrated anti-theft modules in smart energy meters and electricity management terminals. For example, through the smart energy meter and the power consumption management terminal, some abnormal power consumption alarms and records, such as voltage loss, phase failure, meter cover opening and meter programming events, can be realized. H...
