In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The technical solutions provided by various embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

Fig. 1 shows a schematic flow chart of a method for monitoring electricity theft by phase-shifting method according to an embodiment of the present application. It can be seen from Fig. 1 that the present application includes at least steps S110 to S140:

Step S110: Obtain the electric meter type of the target to be monitored.

The target to be monitored can be understood as the user who wants to monitor. The electric meters of existing users are generally smart meters, including single-phase smart meters, three-phase three-wire smart meters, and three-phase four-wire smart meters. Users who use single-phase smart meters The phase-shifting method is rarely used to steal electricity, so this application is mainly applicable to users of three-phase three-wire smart meters and three-phase four-wire smart meters.

This application sets up multi-level monitoring strategies for three-phase three-wire smart meters and three-phase four-wire smart meters respectively. Specifically, for users with current transformers (i.e. metering Users whose magnification is greater than 1), according to the value interval of the threshold value, the maximum value of the absolute value of the current is below the preset threshold value (such as 1A) and the current unbalance coefficient is introduced, and the maximum value of the absolute value of the current is the preset threshold value (such as 1A) and The difference between the absolute value of the current and the negative current of each component are introduced above, and the electricity theft level is divided into three levels: "severe level", "general level" and "slight level", and monitoring sub-strategies are set for each level .

Step S120: Determine the target monitoring strategy for the target to be monitored according to the type of the electric meter, and the target monitoring strategy is a multi-level three-phase three-wire meter monitoring strategy or a multi-level three-wire four-wire meter monitoring strategy.

Then, according to the obtained meter type, determine the target monitoring strategy for the target to be monitored. Simply speaking, if the user's meter type is a three-phase three-wire meter monitoring strategy, then hit the multi-level three-phase three-wire meter monitoring strategy; if the user's meter type If it is a three-phase four-wire meter monitoring strategy, hit the multi-level three-phase four-wire meter monitoring strategy.

Wherein the multi-level three-phase three-wire meter monitoring strategy includes a serious three-phase three-wire meter monitoring sub-strategy, a general three-phase three-wire meter monitoring sub-strategy and a minor three-phase three-wire meter monitoring sub-strategy; the multi-level three-phase three-wire meter monitoring sub-strategy; The meter monitoring strategy includes the three-phase four-wire meter monitoring sub-strategy of the serious level, the three-phase four-wire meter monitoring sub-strategy of the general level and the three-phase four-wire meter monitoring sub-strategy of the minor level.

Step S130: Sampling the electric meter of the target to be monitored to obtain sampling data including multiple collection points.

Then the electric meter of the target to be monitored is sampled, and the sampling can be carried out according to a preset interval, such as once every 1h, there are 24 collection points in a day, and 24 groups of data corresponding to the 24 collection points are obtained, or every Sampling once every 15 minutes, 96 collection points and 96 sets of data corresponding to 96 collection points can be obtained in one day, the preset interval can be set according to the monitoring accuracy, or can be set according to the model of the electric meter, such as an ordinary electric meter, every 1h Sampling once, if it is an HPLC smart energy meter, sampling once every 15 minutes.

Sampling data includes, but is not limited to, the current, voltage, and power factor of each component in the circuit, and the specific sampling data can be set according to the set monitoring strategy, which is not limited in this application.

The process of sampling data may also include processing the collected data. Specifically, the absolute value of the component current may be taken, the difference between the current unbalance coefficient and the current absolute value may be determined according to the current of each component, and the power factor of each component may be determined. And the total power factor determines the power factor ratio, etc.

Take the sampling of a three-phase three-wire meter as an example, and determine the absolute value of the current of the first component, the absolute value of the current of the second component, the current unbalance coefficient, the difference of the absolute value of the current, and the power of the sampling point according to the sampled data Factor ratio; wherein, the difference between the current unbalance coefficient and the absolute value of the current is determined according to the absolute value of the current of the first element and the absolute value of the current of the second element, and the ratio of the power factor is determined according to the first element and the absolute value of the current The power factor of the second component and the total power factor are determined.

Step S140: According to the sampling data and the targeted monitoring strategy, monitor the phase-shifting electricity stealing behavior of the target to be monitored.

Finally, according to the sampling data and the target monitoring strategy of the hit, the phase-shifting electricity stealing behavior of the target to be monitored is monitored. Specifically, the multi-level three-phase three-wire behavior satisfied by each collection point in the sampling data can be determined. A meter monitoring strategy or a sub-strategy in the multi-level three-line four-wire meter monitoring strategy; if the ratio of the number of collection points belonging to a sub-strategy to the total number of collection points in the sampled data is greater than or equal to a preset ratio threshold, then A power theft ticket corresponding to the sub-policy is triggered.

Taking the 24 collection points of a day as an example, determine which sub-strategy in the multi-level three-phase three-wire meter monitoring strategy or the multi-level three-wire four-wire meter monitoring strategy is satisfied for each collected electricity, and set each sub-strategy The number of collection points satisfying the sub-strategy is accumulated, and if the ratio of the number of collection points belonging to a sub-strategy to the total number of collection points in the sampled data is greater than or equal to the preset ratio threshold, triggering the corresponding sub-strategy Electricity theft work order. For example, the preset proportion threshold is 50%. When the number of collection points satisfying a sub-strategy accumulates to 12, it can be determined that the target to be monitored is very likely to have power-stealing behavior, and the power-stealing worker corresponding to the sub-strategy will be triggered. The electricity theft work order will be sent to the staff for further confirmation and review.

It can be seen from the method shown in Figure 1 that the users of the three-phase three-wire meter and three-wire four-wire meter in this application often use the phase-shifting method to steal electricity. According to the law and logical relationship of the multi-level three-phase three-wire meter and multi-level three-wire four-wire meter monitoring strategy, according to the size of the threshold, the stealing behavior of the phase-shifting method is divided into multiple levels, and the corresponding meter type is determined according to the user. monitoring strategy, and sample the user’s electric meter data, and finally, according to the sampling data and the target monitoring strategy, monitor the phase-shifting electricity stealing behavior of the target to be monitored.
