Description

Technical Field

[0001] The present invention relates to the technical field of electricity theft monitoring and identification, and in particular to a method and system for monitoring electricity theft based on high-incidence early warning. Background Art

[0002] With the development of technologies such as remote meter reading, the existing electricity theft technology has also evolved from the original violent disassembly to strong magnetic interference or phase sequence replacement, which makes the monitoring of electricity theft more difficult. In order to realize the online analysis of electricity theft, the Chinese invention patent (application number: CN201811101615) "Electricity theft detection method based on Fourier transform" analyzes the total meter at the gateway and the user's electricity meter to realize the identification of electricity theft behavior and the accurate positioning of the electricity theft user, but there are the following technical problems:

[0003] For power supply companies, the number of users who need to monitor electricity theft is very large. Therefore, if they cannot determine the differentiated monitoring frequency based on the users' early warning data, especially if they cannot strengthen electricity theft monitoring for power users with high incidence of early warnings, they will not be able to accurately and efficiently monitor users' electricity theft behavior.

[0004] When monitoring electricity theft among users, electricity theft behaviors often have a certain clustering. Therefore, under the premise that there is a high-incidence warning for electricity theft behaviors in a fixed area, it is necessary not only to strengthen the analysis of electricity theft behaviors of power users with high-incidence warnings, but also to strengthen the analysis and monitoring of electricity theft behaviors of other users in the area. If the above factors are not taken into account, it is also impossible to accurately and efficiently monitor the electricity theft behaviors of users. Therefore, it is necessary to improve the existing electricity theft monitoring scheme to improve the efficiency and accuracy of monitoring. Summary of the invention

[0005] The purpose of the present invention is to provide a method and system for monitoring electricity theft based on high-incidence early warning, so as to improve the efficiency and accuracy of monitoring.

[0006] To achieve the purpose of the present invention, the technical solution provided by the present invention is as follows:

[0007] First aspect

[0008] The present invention provides a method for monitoring electricity theft based on high-incidence early warning, comprising the following steps:

[0009] Step S1: Divide the power supply area into a plurality of power supply areas to be monitored according to a preset area, and determine the warning assessment amount of the power supply area to be monitored according to the number of historical warnings and the warning time within the power supply area to be monitored;

[0010] Step S2: When the early warning assessment amount of the power supply area to be monitored is greater than the preset alarm threshold, the basic monitoring frequency of the power users in the power supply area to be monitored is determined by the early warning assessment amount, power supply amount and line loss data of the power supply area to be monitored; when the early warning assessment amount of the power supply area to be monitored is not greater than the preset alarm threshold, the basic monitoring frequency of the power users in the power supply area to be monitored is determined by using the first monitoring frequency;

[0011] Step S3: Determine whether there is any abnormality in the historical electricity consumption behavior of the power user according to the historical warning times and warning times of the power users in the power supply area to be monitored; if so, determine the analysis frequency of the power user's electricity theft behavior through the historical warning times, warning times and basic monitoring frequency of the power user; if not, analyze the power user's electricity theft behavior through the basic monitoring frequency.

[0012] Second aspect

[0013] Corresponding to the above method, the present invention provides a power theft behavior monitoring system based on high-incidence early warning, including an early warning evaluation module, a frequency division module and an analysis frequency determination module;

[0014] The early warning assessment module is used to divide the power supply area into a plurality of power supply areas to be monitored according to a preset area, and determine the early warning assessment amount of the power supply area to be monitored according to the number of historical early warnings and the early warning time within the power supply area to be monitored;

[0015] The frequency division module is used to determine the basic monitoring frequency of the power users in the power supply area to be monitored by using the early warning assessment amount, power supply amount and line loss data of the power supply area to be monitored when the early warning assessment amount of the power supply area to be monitored is greater than the preset alarm threshold; when the early warning assessment amount of the power supply area to be monitored is not greater than the preset alarm threshold, the first monitoring frequency is used to determine the basic monitoring frequency of the power users in the power supply area to be monitored;

[0016] The analysis frequency determination module is used to determine whether there is any abnormality in the historical electricity consumption behavior of the power user according to the historical warning times and warning times of the power users in the power supply area to be monitored; if so, the analysis frequency of the power user's electricity theft behavior is determined through the power user's historical warning times, warning times and basic monitoring frequency; if not, the power user's electricity theft behavior is analyzed through the basic monitoring frequency.

[0017] Compared with the prior art, the technical advantages of the present invention are as follows:

[0018] By determining the early warning assessment amount of the power supply area to be monitored based on the historical number of early warnings and the early warning time within the power supply area to be monitored, the accurate division of different power supply areas to be monitored is achieved, the aggregation of power theft behaviors is fully considered, and the foundation is laid for further determination of differentiated monitoring frequencies;

[0019] The basic monitoring frequency of the power users in the power supply area to be monitored is determined by using the early warning assessment amount, power supply amount and line loss data of the power supply area to be monitored, so as to achieve differential evaluation of the monitoring frequency of power users in different power supply areas to be monitored, taking into account not only a single early warning situation, but also the power supply situation and line loss situation, thus laying a foundation for reducing the loss of electricity theft;

[0020] The analysis frequency of the power user's electricity theft behavior is determined by the power user's historical warning times, warning time and basic monitoring frequency, which not only takes into account the basic monitoring frequency of the power user's area, but also provides efficient monitoring for power users with a high incidence of warnings, such as a large number of historical warnings or close warning times.

[0021] Figure 1 A schematic diagram of the method flow provided in an embodiment of the present application. DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, this embodiment provides a method for monitoring electricity theft based on high-incidence early warning, comprising the following steps:

[0024] Step S1: Divide the power supply area into a plurality of power supply areas to be monitored according to a preset area, and determine the warning assessment amount of the power supply area to be monitored according to the number of historical warnings and the warning time within the power supply area to be monitored;

[0025] It should be noted that in step S1, the preset area is dynamically determined based on the area of ​​the power supply area of ​​the power supply enterprise and the number of power users; wherein, the larger the area of ​​the power supply area of ​​the power supply enterprise and the smaller the number of power users, the larger the preset area.

[0026] In one embodiment, a method for determining the early warning assessment amount of the power supply area to be monitored is provided, including the following steps:

[0027] Step S11: Obtain the number of historical warnings and the number of power users with warnings in the power supply area to be monitored, and determine whether the number of historical warnings and the number of power users with warnings in the power supply area to be monitored meet the requirements; if so, proceed to step S12, if not, proceed to step S13;

[0028] Step S12: determining the number of historical warnings within a set time within the power supply area to be monitored and the number of power users with warnings according to the number of historical warnings and the warning time within the power supply area to be monitored, and determining whether the number of historical warnings within a set time within the power supply area to be monitored and the number of power users with warnings meet the requirements; if so, determining the basic monitoring frequency of the power users in the power supply area to be monitored by using the first monitoring frequency; if not, proceeding to step S13;

[0029] Step S13: taking the power users with warnings in the power supply area to be monitored as historical warning users, determining the suspected problem users according to the historical warning times of the historical warning users, and determining the historical evaluation amount of the power supply area to be monitored in combination with the historical warning times and the number of historical warning users in the power supply area to be monitored;

[0030] Step S14: The power users with warnings within the power supply area to be monitored within the set time are regarded as recent warning users, and the key problem users are determined according to the number of historical warnings of the recent warning users within the set time, and the recent warning assessment amount of the power supply area to be monitored is determined in combination with the number of historical warnings within the power supply area to be monitored within the set time and the number of recent warning users;

[0031] Step S15: determining the early warning assessment amount of the power supply area to be monitored according to the recent early warning assessment amount and the historical assessment amount of the power supply area to be monitored.

[0032] Among them, in step S13: determining the suspected problem user according to the historical warning times of the historical warning user is specifically: when the historical warning times of the historical warning user is greater than the preset times, determining the historical warning user as the suspected problem user.

[0033] In another embodiment, another method for determining the early warning assessment amount of the power supply area to be monitored is provided, including the following:

[0034] Step S101: determining a historical warning evaluation amount of the power supply area to be monitored according to a ratio of the number of historical warnings within the power supply area to be monitored to the average number of historical warnings of all the power supply areas to be monitored in the power supply area;

[0035] Step S102: determining a recent warning assessment amount of the power supply area to be monitored according to a ratio of the number of historical warnings within the power supply area to be monitored within a set time to the average number of historical warnings within all power supply areas to be monitored within the power supply area;

[0036] Step S103: Determine the weights of the recent warning assessment amount and the historical warning assessment amount of the power supply area to be monitored according to the number of electricity theft users and the number of electricity users in the history of the power supply area to be monitored, and determine the warning assessment amount of the power supply area to be monitored in combination with the recent warning assessment amount and the historical warning assessment amount of the power supply area to be monitored.

[0037] Step S2: When the early warning assessment amount of the power supply area to be monitored is greater than the preset alarm threshold, the basic monitoring frequency of the power users in the power supply area to be monitored is determined by the early warning assessment amount, power supply amount and line loss data of the power supply area to be monitored; when the early warning assessment amount of the power supply area to be monitored is not greater than the preset alarm threshold, the basic monitoring frequency of the power users in the power supply area to be monitored is determined by using the first monitoring frequency;

[0038] It should be noted that in step S2, when the early warning assessment amount of the power supply area to be monitored is greater than the preset alarm threshold, the basic monitoring frequency of the power users in the power supply area to be monitored is determined by the early warning assessment amount, power supply amount and line loss data of the power supply area to be monitored, including the following:

[0039] Step S21: obtaining the early warning assessment amount of the power supply area to be monitored, and determining whether the early warning assessment amount of the power supply area to be monitored is greater than a preset threshold; if so, determining the basic monitoring frequency of the power users in the power supply area to be monitored by the second monitoring frequency; if not, proceeding to step S22;

[0040] Step S22: obtaining the power supply amount of the power supply area to be monitored, and determining whether it is necessary to determine the basic monitoring frequency of the power supply area to be monitored through the second monitoring frequency according to the power supply amount of the power supply area to be monitored; if so, determining the basic monitoring frequency of the power users in the power supply area to be monitored through the second monitoring frequency; if not, proceeding to step S23;

[0041] Step S23: determining the real-time line loss rate of the power supply area to be monitored according to the real-time power supply amount and the real-time line loss of the power supply area to be monitored, and determining the abnormal line loss amount of the power supply area to be monitored in combination with the real-time line loss of the power supply area to be monitored and the proportion of time when the line loss rate exceeds the standard within a specified time, and determining whether it is necessary to determine the basic monitoring frequency of the power supply area to be monitored through the second monitoring frequency according to the abnormal line loss amount of the power supply area to be monitored; if so, determining the basic monitoring frequency of the power users in the power supply area to be monitored through the second monitoring frequency; if not, proceeding to step S24;

[0042] Step S24: determining the basic monitoring frequency of the power users in the power supply area to be monitored according to the early warning assessment amount, power supply amount and line loss abnormality amount of the power supply area to be monitored.

[0043] It should be noted that the first monitoring frequency is less than the second monitoring frequency, wherein the first monitoring frequency and the second monitoring frequency are determined according to the number of the power supply areas to be monitored and the number of power users. The more the number of power supply areas to be monitored and the more the number of power users, the greater the first monitoring frequency and the second monitoring frequency.

[0044] It should be noted that, in step S23, when the real-time line loss rate of the power supply area to be monitored does not meet the requirement, the abnormal line loss amount of the power supply area to be monitored is determined by the real-time line loss rate of the power supply area to be monitored;

[0045] When the real-time line loss rate of the power supply area to be monitored meets the requirement but the real-time line loss does not meet the requirement, determining the abnormal line loss amount of the power supply area to be monitored according to the real-time line loss of the power supply area to be monitored;

[0046] When the real-time line loss rate and the real-time line loss of the power supply area to be monitored both meet the requirements, the abnormal line loss amount of the power supply area to be monitored is determined by the proportion of time when the line loss rate of the power supply area to be monitored exceeds the standard within a specified time.

[0047] Step S3: Determine whether there is any abnormality in the historical electricity consumption behavior of the power user according to the historical warning times and warning times of the power users in the power supply area to be monitored; if so, determine the analysis frequency of the power user's electricity theft behavior through the historical warning times, warning times and basic monitoring frequency of the power user; if not, analyze the power user's electricity theft behavior through the basic monitoring frequency.

[0048] It should be noted that the method for determining the analysis frequency of the electricity stealing behavior of the power user is:

[0049] Step S31: determine whether the power user has been identified as a power theft user in history. If so, determine the analysis frequency of the power theft behavior of the user according to the power theft amount confirmed in history and the basic monitoring frequency. If not, proceed to step S32.

[0050] Step S32: obtaining the historical warning times of the power user, and determining the historical recommended monitoring frequency of the power user according to the historical warning times of the power user and the basic monitoring frequency;

[0051] Step S33: determining the number of historical warnings of the power user within a set time according to the number of historical warnings of the power user and the warning time, and determining the recommended monitoring frequency of the power user according to the number of historical warnings of the power user within the set time and the basic monitoring frequency;

[0052] Step S34: determining the analysis frequency of the electricity stealing behavior of the electricity user by using the maximum value of the recommended monitoring frequency of the electricity user and the historical recommended monitoring frequency of the electricity user.

[0053] This embodiment determines the early warning assessment amount of the power supply area to be monitored according to the historical number of early warnings and the early warning time within the power supply area to be monitored, thereby achieving accurate division of different power supply areas to be monitored, fully considering the aggregation of power theft behavior, and laying the foundation for further determination of differential monitoring frequencies. The basic monitoring frequency of the power users in the power supply area to be monitored is determined by the early warning assessment amount, power supply and line loss data of the power supply area to be monitored, thereby achieving differential evaluation of the monitoring frequency of power users in different power supply areas to be monitored, taking into account both a single early warning situation and the power supply situation and line loss situation, laying the foundation for reducing power theft losses. The analysis frequency of the power user's power theft behavior is determined by the historical number of early warnings, early warning time and basic monitoring frequency of the power user, taking into account the basic monitoring frequency of the power user's area, and also providing efficient monitoring of power users with high-incidence early warnings such as a large number of historical early warnings or close early warning times.

[0054] In addition, corresponding to the above method, this embodiment also provides a power theft behavior monitoring system based on high-incidence early warning, including an early warning evaluation module, a frequency division module and an analysis frequency determination module;

[0055] The early warning assessment module is used to divide the power supply area into a plurality of power supply areas to be monitored according to a preset area, and determine the early warning assessment amount of the power supply area to be monitored according to the number of historical early warnings and the early warning time within the power supply area to be monitored;

[0056] The frequency division module is used to determine the basic monitoring frequency of the power users in the power supply area to be monitored by using the early warning assessment amount, power supply amount and line loss data of the power supply area to be monitored when the early warning assessment amount of the power supply area to be monitored is greater than the preset alarm threshold; when the early warning assessment amount of the power supply area to be monitored is not greater than the preset alarm threshold, the first monitoring frequency is used to determine the basic monitoring frequency of the power users in the power supply area to be monitored;

[0057] The analysis frequency determination module is used to determine whether there is any abnormality in the historical electricity consumption behavior of the power user according to the historical warning times and warning times of the power users in the power supply area to be monitored; if so, the analysis frequency of the power user's electricity theft behavior is determined through the power user's historical warning times, warning times and basic monitoring frequency; if not, the power user's electricity theft behavior is analyzed through the basic monitoring frequency.

[0058] The preset area is dynamically determined according to the area of ​​the power supply area of ​​the power supply enterprise and the number of power users.
