[0023] Next, exemplary embodiments of the present application will be described in detail with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described herein.

[0024] Figure 1 It is a schematic flow chart of a detection method for screening abnormal users based on line loss rate provided by an exemplary embodiment of the present application. As Figure 1 shown, the detection method for screening abnormal users based on line loss rate includes:

[0025] Step 110: Obtain an abnormal substation area, where the abnormal substation area represents a power supply abnormal area corresponding to a transformer.

[0026] The abnormal substation area represents a power supply abnormal area corresponding to a transformer. By collecting data of multiple substation areas to determine the abnormal substation area, the determination of the abnormal substation area can be made more accurate.

[0027] Step 120: Determine target users with abnormal electricity sales volume in the abnormal substation area.

[0028] Obtain the electricity sales volume of multiple users in the abnormal substation area. By setting a preset electricity sales threshold to determine the abnormality of the electricity sales volume of the target users, that is, if the electricity sales volume is greater than or equal to the preset electricity sales threshold, the corresponding user is the target user.

[0029] Step 130: Send the information containing the target users to an electronic device.

[0030] Sending the information containing the target users to an electronic device, it can be understood that the electronic device receives the information containing the target users to determine which target users have abnormal electricity consumption, etc.

[0031] A detection method for screening abnormal users based on line loss rate provided by the present application includes: obtaining an abnormal substation area, where the abnormal substation area represents a power supply abnormal area corresponding to a transformer, determining target users with abnormal line loss rate and electricity sales volume in the abnormal substation area, and sending the information containing the target users to an electronic device. By obtaining the abnormal substation area, then determining the target users with abnormal electricity sales volume in the abnormal substation area, and thus sending the information containing the target users to an electronic device, so that the staff can perform corresponding maintenance.

[0032] Figure 2 It is a schematic flow chart of an abnormal annotation method provided by an exemplary embodiment of the present application. As Figure 2 shown, step 110 may include:

[0033] Step 111: Collect the electricity consumption information of each user in multiple substation areas, where the electricity consumption information includes current and voltage.

[0034] Collect the electricity consumption information of each user in multiple substation areas. By collecting the electricity consumption information, it is determined whether the current and voltage of each user are abnormal.

[0035] Step 112: Determine the metering category corresponding to each user according to the current and voltage, where the metering category includes an abnormal category, and the abnormal category indicates that the current and / or voltage is abnormal.

[0036] According to the current and voltage, the metering category corresponding to each user can be determined, and the metering category can include: normal voltage, normal current, voltage loss, current reverse phase, overcurrent, current loss, zero-fire line current imbalance of single-box but energy meter, zero voltage with current, phase sequence abnormality, and low voltage, etc. The abnormal category includes: voltage loss, current reverse phase, overcurrent, current loss, zero-fire line current imbalance of single-box but energy meter, zero voltage with current, phase sequence abnormality, and low voltage, etc.

[0037] Step 113: Determine the maintenance priority of each user according to the abnormal category.

[0038] Determine the maintenance priority of each user according to the abnormal category. For example, the maintenance priority of overcurrent is higher than that of low voltage.

[0039] Step 114: Mark the abnormal areas corresponding to the users with a maintenance priority higher than the preset priority.

[0040] Mark the abnormal areas corresponding to the users with a maintenance priority, so that the staff can perform priority maintenance according to the maintenance priority.

[0041] Figure 3 It is a schematic flow chart of a method for obtaining an abnormal area provided by an exemplary embodiment of the present application. As Figure 3 shown, step 110 may include:

[0042] Step 115: Obtain the power supply and sold electricity of multiple areas.

[0043] The power supply and sold electricity of multiple areas can be obtained from the data storage, or the power supply and sold electricity of multiple areas can be obtained in real time.

[0044] Step 116: Calculate the line loss rate corresponding to each area according to the power supply and sold electricity.

[0045] The line loss rate is equal to the difference between the power supply and the sold electricity, and the value obtained by dividing the difference by the power supply is the line loss rate.

[0046] Step 117: Select the areas with a line loss rate greater than or equal to the preset line loss threshold as abnormal areas.

[0047] Select the areas with a line loss rate greater than or equal to the preset line loss threshold as abnormal areas. The abnormal areas can be provided with geographical locations to facilitate the operators to determine the specific locations of the abnormal areas and facilitate searching.

[0048] In one embodiment, step 1142 may be specifically implemented as follows: Obtain captured images corresponding to multiple power distribution areas, determine on-site behavior actions based on the captured images, determine abnormal actions among the on-site behavior actions, and use the power distribution areas containing abnormal actions as abnormal power distribution areas.

[0049] Obtain captured images corresponding to multiple power distribution areas, that is, set multiple cameras on-site, so that videos, pictures, etc. of the on-site can be obtained through the multiple cameras. Then determine on-site behavior actions based on the captured images. The on-site behavior actions include actions such as touching the meter box, touching the wire, staff holding pliers, screwdrivers, insulating tape, and wearing gloves. Each on-site behavior action will affect the abnormality of the transformer. Therefore, the above on-site behavior actions can also be stored, as well as the corresponding relationship between each on-site behavior action and the possible impacts caused by the on-site behavior action. For example, if the on-site behavior action is that the staff touches the wire, voltage loss may occur if the staff touches the wire. It can be understood that one on-site behavior action can correspond to multiple abnormal problems. That is, the action of touching the wire can not only cause voltage loss but also cause current loss.

[0050] Figure 4 It is a flowchart of a method for sending target user information provided by an exemplary embodiment of the present application. As Figure 4 shown, step 130 may include:

[0051] Step 131: Obtain the line loss rate of the abnormal power distribution area within a preset period.

[0052] Obtain the line loss rate of the abnormal power distribution area within a preset period. For example, the line loss rate within one month or one week can be obtained.

[0053] Step 132: Calculate the operation index corresponding to the abnormal power distribution area according to the line loss rate within the preset period, where the operation index characterizes the operation state of the transformer corresponding to the abnormal power distribution area.

[0054] Calculate the operation index corresponding to the abnormal power distribution area according to the line loss rate within the preset period, and the operation index characterizes the operation state of the transformer corresponding to the abnormal power distribution area.

[0055] Step 133: Send the operation index corresponding to the abnormal power distribution area and the information containing the target user to the electronic device.

[0056] In one embodiment, step 132 may be specifically implemented as follows: Calculate the trend index corresponding to the abnormal power distribution area according to the line loss rate within the preset period, where the trend index includes an upward trend index and a downward trend index.

[0057] Calculate the trend index corresponding to the abnormal substation area based on the line loss rate within a preset period, and determine the operating state of the transformer through the trend index. The trend index includes an upward trend index and a downward trend index. The upward trend index indicates that the line loss rate increases within a certain period of time, and the downward trend index indicates that the line loss rate decreases within a certain period of time.

[0058] In one embodiment, step 132 can be specifically implemented as follows: Arrange the line loss rates of the abnormal substation area within a preset period in chronological order to obtain the line loss rate sequence of the abnormal substation area. Take the line loss rate corresponding to the time period in the line loss rate sequence that is greater than the target line loss rate as the upward trend index, and take the line loss rate corresponding to the time period in the line loss rate sequence that is less than the target line loss rate as the downward trend index.

[0059] Arrange the line loss rates of the abnormal substation area within a preset period in chronological order to obtain the line loss rate sequence of the abnormal substation area. Set the target line loss rate. If the number of line loss rates exceeding the target line loss rate within a certain period is greater than or equal to the preset quantity threshold, then the line loss rate within this period corresponds to the upward trend index, indicating that there is a problem of excessive voltage in the transformer. If the number of line loss rates lower than the target line loss rate within a certain period is less than the preset quantity threshold, then the line loss rate within this period corresponds to the downward trend index. According to the line loss rate sequence, multiple downward trend indexes and multiple upward trend indexes can be obtained. Through the upward trend index and the downward trend index, the time period with abnormal line loss rate can be intuitively determined. Then, determine whether the electricity consumption is normal during this period based on the electricity sales volume or electricity consumption volume during this period. For example, the electricity consumption is relatively high between 7 pm and 8 pm. If the line loss rate is higher than the target line loss rate value, it indicates that the electricity consumption during this period is abnormal.
