With the development of economic technology and the improvement of living standard of people, electric energy becomes essential secondary energy in production and life of people, and brings endless convenience to production and life of people. However, as electric energy is popularized, electricity stealing phenomena are becoming more and more serious. If the electricity stealing phenomenon cannot be found and corrected in time, the electricity stealing brings economic loss of not only the power system, but also operation accidents of the power grid and the like more likely to be caused.
At the present stage, the rural power grid distribution wiring is relatively dispersed, and due to the factors such as system cost, communication pressure, system simplification and consideration, the power utilization acquisition system is not provided with the functions of phase splitting and real-time online monitoring during power grid construction, so that the management of the line loss of a transformer area is relatively blind, and the investigation and the location of electricity stealing become very difficult.
The current common electricity stealing analysis method usually needs a large amount of basic data and adopts a more complex analysis method. The rural power grid is a relatively simple and scattered power grid area, basic data acquisition is difficult, and the method is not suitable for the existing complex analysis algorithm.

s2, selecting a distribution area with the line loss larger than a first set value according to the operation data obtained in the step S1;
s3, checking data of the three-phase electric energy meter except the gateway meter under the station area selected in the step S2, and selecting specific time for judging electricity stealing;

s7, selecting phase lines with the line loss larger than a second set value as target phase lines according to the line loss of each phase line obtained in the step S6, and performing electricity stealing troubleshooting on the single-phase electric energy meter under the target phase lines;
s8, if the line loss of each phase line calculated in the step S6 is larger than a third set value and the total electric quantity of all the single-phase electric energy meters under each phase line is larger than a fourth set value, segmenting the analysis time period, and calculating the line loss of each segmentation time period;
and S9, according to the line loss of the sectional time calculated in the step S8, carrying out electricity stealing troubleshooting on the sectional time of which the line loss is greater than the fifth set value, and simultaneously carrying out electricity stealing troubleshooting on the phase line of which the line loss is greater than the sixth set value in the sectional time of which the line loss is greater than the fifth set value.
And S3, checking the data of the three-phase electric energy meter except the gateway meter, so as to select the specific time for judging electricity stealing, specifically checking the electricity consumption of the three-phase electric energy meter except the gateway meter for one day, and selecting the day with the electricity consumption of 0 or the day with the electricity consumption less than a seventh set value as the specific time for judging electricity stealing.
Step S6, calculating the line loss of each phase line, specifically, dividing the total electric quantity of all the single-phase electric energy meters under the phase line by the electric quantity sold by the phase line recorded by the gateway meter, so as to obtain the line loss of the phase line.
The analysis time period is segmented in the step S8, specifically, the time period on the day of analysis is divided into a tip time period, a peak time period, a flat time period and a valley time period, the valley time period is 23: 00-7: 00, the tip time period is 10: 30-11: 30 and 19: 00-21: 00, the peak time period is 8: 30-10: 30, 18: 00-19: 00 and 21: 00-23: 00, and the rest time periods on the day of analysis are flat time periods.
According to the method for searching for electricity stealing in a phase-splitting and time-dividing manner, the range of electricity stealing investigation is greatly reduced and the labor intensity is reduced through phase-splitting statistics of line loss of the transformer area; meanwhile, for part of special conditions, line loss of the transformer area is counted in different time periods through data returned in the acquisition system, then key investigation is carried out on the time period with high line loss and a phase line, the electricity stealing position can be quickly locked, the investigation working range is small, and the efficiency is high; in addition, the method of the invention also has the advantages of accuracy, simplicity and reliability.
