"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists singly, A and B exist simultaneously, and B exists singly, wherein A and B can be singular or plural. In the written description of this application, the character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The technical scheme provided by the embodiment of the application can be applied to an electric power monitoring scene, particularly to a detection scene of abnormal electricity utilization. In daily electricity consumption, the electricity consumption may be divided into a peak period, a normal period, and a valley period according to the difference in electricity consumption. In general, the electricity prices during the peak period are higher than those during the usual time period, which is higher than those during the valley period. At present, some electricity stealing users keep the total electricity consumption unchanged by modifying the timing period parameters of the electricity meters, but charge the electricity in the high electricity charge period into the low electricity charge period, so as to reduce the total electricity charge of the users and achieve the purpose of electricity stealing.
The peak period generally refers to a period corresponding to a peak period of power consumption in a day. The valley period generally refers to a period corresponding to a low valley period of power consumption in a day, and the ordinary period generally refers to a period corresponding to normal power consumption in a day.

It is to be understood that the following detailed description may be combined with other embodiments, and that the same or similar concepts or processes may not be repeated in some embodiments.

Illustratively, the voltage may be a high frequency 96-point voltage and the current may be a high frequency 96-point current.
For example, when the power consumption data of the target user in the target time period within the preset time period is obtained, the initial power consumption data of the target user in the target time period may be obtained first; and screening and checking the initial power consumption data, and eliminating null value power consumption data to obtain the power consumption data of the target user in the target time period. Therefore, the data quality of the acquired electricity utilization data of the target user in the target time period can be effectively improved by preprocessing the initial electricity utilization data.
For example, when the first electric quantity measured by the electric meter in the target time period is obtained, the forward active indication value difference and the reverse active indication value difference in the target time period measured by the electric meter may be obtained, and the first electric quantity measured by the electric meter in the target time period may be determined according to the forward active indication value difference and the reverse active indication value difference in the target time period measured by the electric meter.
For example, when determining the first power consumption of the target time interval measured by the electric meter according to the forward active value difference and the reverse active value difference of the target time interval measured by the electric meter, see the following formula 1:

After the voltage, the current and the electricity consumption measured by the electricity meter in the target time period are respectively obtained, the following S102 may be executed:
s102, determining a power consumption ratio corresponding to a target time interval and a power consumption difference corresponding to the target time interval according to the voltage, the current and the first power consumption of the target time interval; and determining a first numerical value according to the estimated power consumption in the preset time and the second electric quantity in the preset time measured by the electric meter.
For example, in the embodiment of the present application, when determining the power consumption ratio corresponding to the target time interval and the power consumption difference corresponding to the target time interval according to the voltage, the current and the first power consumption in the target time interval, a first estimated power consumption in the target time interval may be determined according to the voltage and the current in the target time interval; calculating the ratio of the first electric quantity to the first estimated electric quantity, and determining the ratio of the first electric quantity to the first estimated electric quantity as the electric quantity ratio corresponding to the target time interval; and calculating a difference value between the first electric quantity and the first estimated electric consumption, and determining the difference value between the first electric quantity and the first estimated electric consumption as an electric consumption difference value corresponding to the target time period.
For example, when the first estimated power consumption amount of the target period is determined according to the voltage and the current of the target period, the following formula 2 can be referred to:
wherein R represents a first estimated power usage for a target time period and U represents a target time periodA voltage, I represents a current for a target period, t represents a target period,
representing a power factor.
In conjunction with equation 2 above, the first estimated power consumption for the peak period may be calculated by
A first estimated power usage for a peak period is determined, wherein,

representing the peak period. When calculating the first estimated power usage for flat time periods, the method may be performed
Determining a first estimated power usage for the flat time period; wherein the content of the first and second substances,

Determining a first estimated power usage during the valley period; wherein, the first and the second end of the pipe are connected with each other,

indicating a valley period.
In combination with the above description, in determiningWhen the electricity consumption ratio and the electricity consumption difference value corresponding to the peak time interval are used, the first electricity consumption of the peak time interval measured by the electricity meter can be measured

Determining the ratio of (A) to (B) as the power consumption ratio corresponding to the peak time period, and recording the power consumption ratio as K1; first electric quantity of peak time interval measured by electric meter
First estimated power usage from peak hours
The difference value of (A) is determined as the power consumption difference value corresponding to the peak time period and can be recorded as
. Similarly, when the corresponding electricity consumption ratio and the electricity consumption difference value of the ordinary time period are determined, the first electricity consumption of the ordinary time period can be measured by the electricity meter
First estimated power consumption from flat time period
The ratio of (2) is determined as the power consumption ratio corresponding to the average time period and can be marked as K2; first electricity quantity of flat time period measured by electric meter

The difference is determined as the difference of the electric quantity corresponding to the average time period and can be recorded as
. When the electricity consumption ratio and the electricity consumption difference corresponding to the valley period are determined, the first electricity consumption of the valley period measured by the electricity meter can be measured

And determining the power consumption ratio corresponding to the peak time period, the ordinary time period and the valley time period and the power consumption difference corresponding to the target time period.
For example, in the embodiment of the present application, before determining the first value according to the estimated power consumption in the preset time period and the second power consumption in the preset time period measured by the electric meter, it is required to determine the estimated power consumption in the preset time period and the second power consumption in the preset time period measured by the electric meter, respectively.
For example, when determining the estimated power consumption within the preset time period, in one possible manner, the voltage and the current within the preset time period may be obtained separately, and the estimated power consumption within the preset time period may be calculated and determined in combination with the above formula 2. In another possible manner, the first estimated power consumption in the peak period, the first estimated power consumption in the average period, and the first estimated power consumption in the valley period may be obtained, respectively, and the sum of the first estimated power consumption in the peak period, the first estimated power consumption in the average period, and the first estimated power consumption in the valley period may be determined as the estimated power consumption in the preset duration, so as to determine the estimated power consumption in the preset duration.
For example, when determining the second electric quantity within the preset time duration measured by the electric meter, the forward active indication difference and the reverse active indication difference within the preset time duration measured by the electric meter may be respectively determined, and the second electric quantity within the preset time duration measured by the electric meter is determined according to the forward active indication difference and the reverse active indication difference within the preset time duration measured by the electric meter, which is similar to the manner of determining the first electric quantity within the target time duration measured by the electric meter, reference may be made to the above description on determining the first electric quantity within the target time duration measured by the electric meter, and here, the embodiments of the present application are not described in detail again.
For example, in the embodiment of the present application, when determining the first value according to the estimated power consumption in the preset time period and the second electricity consumption in the preset time period measured by the electricity meter, a first difference between the estimated power consumption in the preset time period and the second electricity consumption may be determined; the ratio of the first difference to the second amount of electricity is determined as a first value, which is determined by referring to equation 3 below.
Wherein, R1 represents the estimated power consumption in the preset time, R2 represents the second power consumption in the preset time measured by the electric meter, and K4 represents the first numerical value.
It should be noted that, in the embodiment of the present application, when the estimated power consumption within the preset time duration is determined by calculating according to the formula 2, the load curve UI in the formula 2 is an adaptive power curve, the curve collection density has multiple sampling manners of 24 × 2n points/day, the minimum density is 24 points/day, and the maximum density is 1440 points/day. The first value K4 may be used to determine a deviation order of magnitude between the electric quantity estimated by the active power and the accumulated electric quantity calculated by the actual electric meter, and the deviation order of magnitude is usually within a range of
N is selected according to the user type. If the first value K4 exceeds the range threshold of the deviation magnitude, the curve sampling frequency can be improved, the similarity value under a high-frequency curve is calculated in an iterative mode, the deviation between the electric quantity calculated by adopting power fitting and the electric quantity measured by the electric energy meter is within the constraint range, and the reliability of the power fitting result is ensured, so that the calculation efficiency and the calculation result accuracy can be improved at the same time. If the sampling frequency of the maximum data density curve still exceeds the range threshold value of the deviation magnitude, the electric meter is indicated to be an electric energy meter to be identified as an error, and maintenance personnel are informed to examine the metering error of the electric energy meter on the standard platform body.
With reference to the above description, after the power consumption ratio corresponding to the target time interval, the power consumption difference corresponding to the target time interval, and the first numerical value are respectively determined, the following S103 may be executed:
s103, determining an electricity utilization detection result of the target user in a preset time length according to the electricity utilization ratio corresponding to the target time period, the electricity utilization difference corresponding to the target time period and the first numerical value; wherein, the electricity utilization detection result comprises normal electricity utilization or abnormal electricity utilization.
For example, when determining the power consumption detection result of the target user in the preset time period, considering that the preset time period may include a peak time period, a normal time period, and a valley time period, in this embodiment of the application, when determining the power consumption detection result of the target user in the preset time period according to the power consumption ratio corresponding to the target time period, the power consumption difference corresponding to the target time period, and the first numerical value, the following three possible implementation manners may be included:
in a possible implementation manner, if the power consumption ratio corresponding to the peak time period is smaller than the second numerical value, and the difference between the power consumption difference corresponding to the peak time period and the power consumption difference corresponding to the valley time period is smaller than the first preset threshold, it is determined that the target user has abnormal power consumption in both the peak time period and the valley time period.
The value of the first preset threshold can be set according to actual needs. In the embodiment of the present application, it is intended to define that the difference between the power consumption corresponding to the peak time period and the power consumption corresponding to the valley time period is approximately equal to each other by defining that the difference between the power consumption difference corresponding to the peak time period and the power consumption difference corresponding to the valley time period is smaller than a first preset threshold.
The second value is the product of the first value and a predetermined value. For example, the preset value may be 0.8, 0.7, 0.75, and the like, and may be specifically set according to actual needs.
Taking a preset numerical value of 0.8 as an example, if the power consumption ratio K1 corresponding to the peak time period is less than K4 × 0.8, and the power consumption difference value delta peak corresponding to the peak time period is approximately equal to delta valley, determining that the power consumption of the target user is abnormal in both the peak time period and the valley time period, and thus determining the power consumption detection results of the target user in the peak time period and the valley time period.
In another possible implementation manner, if the power consumption ratio corresponding to the ordinary time period is smaller than the second numerical value, and the difference between the power consumption difference corresponding to the ordinary time period and the power consumption difference corresponding to the valley time period is smaller than the second preset threshold, it is determined that the target user has abnormal power consumption in the ordinary time period and the valley time period.
The value of the second preset threshold can be set according to actual needs. In the embodiment of the application, the difference between the power consumption difference corresponding to the ordinary time period and the power consumption difference corresponding to the valley time period is limited to be smaller than the second preset threshold, so that the purpose of limiting that the power consumption difference corresponding to the ordinary time period is approximately equal to the power consumption difference corresponding to the valley time period is achieved.
Taking the preset numerical value as 0.8 as an example, if the power consumption ratio K2 corresponding to the ordinary time period is less than K4 x 0.8, and the power consumption difference value delta average corresponding to the ordinary time period is approximately equal to delta valley, it is determined that the power consumption of the target user is abnormal in the ordinary time period and the valley time period, and thus, the power consumption detection results of the target user in the ordinary time period and the valley time period are determined.
In another possible implementation manner, if the power consumption ratio corresponding to the valley period is smaller than the second numerical value, the sum of the power consumption difference corresponding to the peak period and the power consumption difference corresponding to the ordinary period, and the difference between the power consumption differences corresponding to the valley period is smaller than the third preset threshold, it is determined that the target user has abnormal power consumption in the peak period, the ordinary period, and the valley period.
The value of the third preset threshold can be set according to actual needs. In the embodiment of the present application, the sum of the power consumption difference corresponding to the peak time period and the power consumption difference corresponding to the ordinary time period is defined, and the difference between the power consumption differences corresponding to the valley time period is smaller than a third preset threshold, so as to define that the sum of the power consumption difference corresponding to the peak time period and the power consumption difference corresponding to the ordinary time period is approximately equal to the power consumption difference corresponding to the valley time period.
It should be noted that the first preset threshold, the second preset threshold, and the third preset threshold may be equal or unequal, and may be specifically set according to an actual need, where the embodiment of the present application is not specifically limited.
Taking a preset numerical value of 0.8 as an example, if the power consumption ratio K3 corresponding to the valley period is less than K4 × 0.8, and the Δ peak + Δ average is approximately equal to the Δ valley, it is determined that the power consumption of the target user is abnormal in the peak period, the ordinary period, and the valley period, so as to determine the power consumption detection results of the target user in the peak period, the ordinary period, and the valley period.
In addition, after the abnormal result of the electricity utilization in the target time period in the preset time period is detected, the abnormal time period can be marked and tracked, and the abnormal result can be output.
According to the embodiment of the application, the electricity utilization data of the target user in the target time period within the preset time period are obtained, the target time period comprises a peak time period, a normal time period and a valley time period, and the electricity utilization data comprise voltage, current and first electricity consumption measured by an electricity meter; determining a power consumption ratio corresponding to the target time period and a power consumption difference corresponding to the target time period according to the voltage, the current and the first power consumption of the target time period; determining a first numerical value according to the estimated power consumption in the preset time and the second power consumption in the preset time measured by the electric meter; determining a power utilization detection result of a target user in a preset time according to the power utilization ratio corresponding to the target time interval, the power utilization difference corresponding to the target time interval and the first numerical value; wherein, the electricity utilization detection result comprises normal electricity utilization or abnormal electricity utilization. In this way, the power consumption detection result of the target user in the preset time period is determined together by combining the power consumption ratio corresponding to the target time period, the power consumption difference corresponding to the target time period and the first numerical value, so that the abnormal power consumption condition of the target user in the preset time period can be automatically detected, and the detection efficiency of the abnormal power consumption is effectively improved.
Based on the embodiment shown in fig. 1, if the power consumption detection result of the target user in the preset time period is abnormal, determining power consumption detection results of a plurality of continuous historical preset time periods before the preset time period; and if the power utilization detection results of the plurality of continuous historical preset durations are all power utilization abnormity and the power consumption of the historical preset durations measured by the electric meter is larger than the average value of the power consumption corresponding to the target user, outputting abnormity prompt information.
For example, if it is detected that the electricity consumption of the user is abnormal in 8 months and 20 days in XXXX, and the electricity consumption is abnormal in t-1 consecutive days, that is, the number of consecutive days of the electricity abnormality reaches t days, and the average value of the daily frozen electric energy indication values of each day in the t days is greater than K5, the abnormality prompt message is output.
Wherein, the value of t can be set according to actual needs. For example, in the embodiment of the present application, t may be 7, and K5 is an average value of daily frozen power indication values corresponding to the target user. Illustratively, K5 may be greater than 1.5.
