Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to power distribution network technology, in particular to a power stealing point detection method, device, system, server and storage medium. BACKGROUND

[0002] Line loss is an important index of power system, in addition to the loss in the transmission process of distribution line, another important reason is that the power user steals electricity to evade electricity charges. Power stealing is a kind of illegal behavior, and is also an important content of power supply regulation, but the current power stealing investigation is mainly based on monitoring the in-out line current and voltage of the electric energy meter, and the power stealing mode without electric energy meter, such as the mode of connecting the main line, cannot be monitored. For the power stealing mode of connecting the main line, the current method can only check by artificial line inspection, which consumes a lot of manpower, cannot determine whether there is power stealing on the line, and cannot determine the specific position of power stealing. At the same time, the power stealing by connecting the main power line is usually hidden very deeply, even if personnel are arranged to patrol the line, it is not necessarily timely to find out, and if the power stealing time is long, there will be disputes in pursuing the electricity charges even if the power stealing is caught.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0048] Figure 1 This is a flowchart of a method for detecting electricity theft points according to an embodiment of the present invention. This embodiment is applicable to detecting the location of electricity theft points in a power distribution network. The method can be executed by an electricity theft point detection device, such as... Figure 1 As shown, the method specifically includes the following steps:

[0049] S110. Acquire the main line current signals collected by each first main power acquisition device; acquire the incoming line current signals of each main power meter, each first-level power meter, and each second-level power meter; acquire the first-level branch line current signals collected by each first-level power acquisition device; acquire the second-level branch line current signals collected by each first-level power acquisition device.

[0050] This method for detecting electricity theft points is applied to the distribution network system of transformer substations. Figure 2 This is a schematic diagram of the structure of the distribution network system provided in the embodiment of the present invention, as shown below. Figure 2 As shown, the distribution network system of this area includes a transformer I, at least one main line A, at least one primary branch line B branching from each main line A, and at least one secondary branch line C branching from each primary branch line B; each main line A is equipped with at least one main energy meter Qa and at least one main energy acquisition device Fa; each primary branch line B is equipped with at least one primary energy meter Qb and at least one primary energy acquisition device Fb; each secondary branch line C is equipped with at least one secondary energy meter Qc and at least one secondary energy acquisition device Fc; at least one main energy acquisition device Fa includes a first main energy acquisition device Fa1; at least one primary energy acquisition device Fb includes a first primary energy acquisition device Fb1; at least one secondary energy acquisition device Fc includes a first secondary energy acquisition device Fc1.

[0051] Here, we take three main trunk lines A1, A2, and A3 as an example, from which three primary branch lines B1, B2, and B3 branch off; and from the primary branch line B1, two secondary branch lines C1 and C2 branch off. The first primary power acquisition device Fa1 collects the current signals IA1, IA2, and IA3 of each main trunk line; and the first primary power acquisition device Fb1 collects the current signals IB1, IB2, and IB3 of each primary branch line. It can be understood that each first primary power acquisition device Fb1 represents all the first-level current signals on each primary branch line corresponding to each main trunk line. The diagram only shows the first-level energy acquisition device Fb1 on the main line A1, collecting the current signals IB1, IB2, and IB3 of each primary branch line; and the second-level energy acquisition devices IC1 and IC2, collecting the current signals of each secondary branch line. Here, each first-level energy acquisition device Fc1 refers to all the first-level and second-level energy acquisition devices Fc1 on each primary branch line. The diagram only shows the second-level energy acquisition devices IC1 and IC2 collected by the first-level and second-level energy acquisition device Fc1 on the primary branch line B1.

[0052] The incoming current signals IA1-1, IA1-2, and IA1-3 of each main energy meter Qa (which can be understood as the incoming current signals of all main energy meters Qa on each main line; the diagram only shows the incoming current signals A1-1, A1-2, and A1-3 of each main energy meter Qa on main line A1), and the incoming current signals IB1-1, IB1-2, and IB1-3 of each primary energy meter Qb (which can be understood as the incoming current signals of all primary energy meters Qb on each primary branch line). The diagram only shows the incoming current signals of each primary energy meter Qb on the primary branch line B1 (IB1-1, IB1-2, IB1-3), and the incoming current signals of each secondary energy meter IC1-1, IC1-2 (which can be understood as the incoming current signals of all secondary energy meters Qc on each secondary branch line; the diagram only shows the incoming current signals of each secondary energy meter Qc on the secondary branch line C1).

[0053] S120. Determine whether the sum of the incoming current signals of each main energy meter, each primary energy meter, and each secondary energy meter is the same as the sum of the main line current signals.

[0054] S130. If they are not the same, determine whether the current signal of any main trunk line collected by any first main power acquisition device is the same as the sum of the current signals of each corresponding first-level branch trunk line and the sum of the incoming current signals of each main power meter on the main trunk line.

[0055] S140. If they are the same, determine whether the current signal of any first-level branch line collected by any first-level power acquisition device is the same as the sum of the current signals of each corresponding second-level branch line and the sum of the incoming current signals of each first-level power meter on the first-level branch line.

[0056] S150. If they are not the same, then the electricity theft point is determined to be on the primary branch line.

[0057] Specifically, if the incoming current signals of all electricity meters equal the current signals of each main line, then there are no points of electricity theft in the distribution network system. Conversely, if the incoming current signals of all electricity meters differ from the current signals of each main line, then there are points of electricity theft in the distribution network system. Here, we take... Figure 2 Taking the wiring of a power distribution network system as an example, when (IA1-1+IA1-2+IA1-3+IB1-1+IB1-2+IB1-3+IC1-1+IC1-2) and (IA1+IA2+IA3) are not equal, there is a point of electricity theft in the power distribution network system. Then, it is determined whether the equation IA1=IB1+IB2+IB3+(IA1-1+IA1-2+IA1-3) is true. If it is true, the point of electricity theft is excluded from the main line A1. Then, it is determined whether the equation IB1=IC1+IC2+(IB1-1+IB1-2+IB1-3) is true. If it is not true, the point of electricity theft is determined to be on the first-level branch line B1. In this way, this solution realizes the automatic and accurate detection of the location of electricity theft points in the power distribution network by the fact that the inflow current of the node is not equal to the outflow current, avoiding the problem of a large amount of manpower wasted by manual line inspection.

[0058] Optionally, based on the above embodiments, the specific location of the electricity theft point on the primary branch trunk line can be further determined, such as... Figure 2 As shown, taking a first-level branch line B1 on the main line A1 as an example, at least one main power acquisition device includes a second main power acquisition device Fa2, a third main power acquisition device Fa3, and a fourth main power acquisition device Fa4; at least one main power meter includes a first main power meter Qa1, a second main power meter Qa2, and a third main power meter Qa3; at least one first-level power acquisition device Fb also includes a second first-level power acquisition device Fb2, a third first-level power acquisition device Fb3, and a fourth first-level power acquisition device Fb4; at least one first-level power meter includes a first first-level power meter Qb1, a second first-level power meter Qb2, and a third first-level power meter Qb3. Figure 3 This is a flowchart of another electricity theft detection method provided in an embodiment of the present invention, such as... Figure 3 As shown, the method includes:

[0059] S210. Acquire the main line current signals collected by each first main power acquisition device; acquire the incoming line current signals of each main power meter, each first-level power meter, and each second-level power meter; acquire the first-level branch line current signals collected by each first-level power acquisition device; acquire the second-level branch line current signals collected by each first-level power acquisition device.

[0060] S220. Determine whether the sum of the incoming current signals of each main energy meter, each primary energy meter, and each secondary energy meter is the same as the sum of the main line current signals.

[0061] S230. If they are not the same, determine whether the current signal of any main trunk line collected by any first main power acquisition device is the same as the sum of the current signals of each corresponding first-level branch trunk line and the sum of the incoming current signals of each main power meter on the main trunk line.

[0062] S240. If they are not the same, determine whether the current signal collected by the first main power acquisition device is the same as the sum of the current signal collected by the second main power acquisition device and the incoming current signal of the first main power meter; and execute S241-S243.

[0063] S241. If they are the same, determine whether the current signal collected by the second main power acquisition device is the same as the sum of the current signal collected by the third main power acquisition device and the incoming current signal of the second main power meter.

[0064] S242. If they are the same, determine whether the current signal collected by the third main power acquisition device is the same as the sum of the current signal collected by the fourth main power acquisition device and the incoming current signal of the third main power meter.

[0065] S243. If they are not the same, the electricity theft point is located between the third main power acquisition device and the fourth main power acquisition device.

[0066] When a point of electricity theft exists in the distribution network system, the system then checks whether the equation IA1 = IB1 + IB2 + IB3 + (IA1-1 + IA1-2 + IA1-3) holds true. If it does not, the point of electricity theft is on the main line A1. To further determine the specific location of the point of electricity theft on the main line A1, the system first checks whether the equation IA1(IA11) = IA1-1 + IA12 holds true. If it does, the system determines that there is no point of electricity theft between the first main power acquisition device Fa1 and the second main power acquisition device Fa2. Next, the system checks whether the equation IA12 = IA1-2 + IA13 holds true. If it does, the system determines that there is no point of electricity theft between the second main power acquisition device Fa2 and the third main power acquisition device Fa3. Next, the system checks whether the equation IA13 = IA1-3 + IA14 holds true. If it does not, the system determines that there is a point of electricity theft between the third main power acquisition device Fa2 and the fourth main power acquisition device Fa3. This solution further determines the specific location of the electricity theft point on the main and branch lines, thus accurately locating the electricity theft point.

[0067] S250. If the judgment result of step S230 is yes, determine whether the current signal of any first-level branch line collected by any first-level power acquisition device is the same as the sum of the current signals of each corresponding second-level branch line and the sum of the incoming current signals of each first-level power meter on the first-level branch line; and execute S251-S254.

[0068] S251. If they are not the same, determine whether the current signal collected by the first-level energy acquisition device is the same as the sum of the current signal collected by the second-level energy acquisition device and the incoming current signal of the first-level energy meter.

[0069] S252. If they are the same, determine whether the current signal collected by the second-level energy acquisition device is the same as the sum of the current signal collected by the third-level energy acquisition device and the incoming current signal of the second-level energy meter.

[0070] S253. If they are the same, determine whether the current signal collected by the third-level energy acquisition device is the same as the sum of the current signal collected by the fourth-level energy acquisition device and the incoming current signal of the third-level energy meter.

[0071] S254. If they are not the same, the electricity theft point is located between the third-level power collection device and the fourth-level power collection device.

[0072] If a point of electricity theft exists in the distribution network system, then it is determined whether the equation IA1 = IB1 + IB2 + IB3 + (IA1-1, IA1-2, IA1-3) holds true. If it holds true, the point of electricity theft is excluded from being on the main line A1. Next, it is determined whether the equation IB1 = IC1 + IC2 + (IB1-1, IB1-2, IB1-3) holds true. If it does not hold true, the point of electricity theft is on the primary line B1. Then, the specific location of the point of electricity theft on the primary line B1 is determined. First, it is determined whether IB1(IB11) = IB1-1 + IB1 The system checks whether equation 2 holds true. If it does, there is no point of electricity theft between the first-level power acquisition device Fb1 and the second-level power acquisition device Fb2. Next, it checks whether equation IB2 = IB1 - 2 + IB13 holds true. If it does, there is no point of electricity theft between the second-level power acquisition device Fb2 and the third main power acquisition device Fb3. Then, it checks whether equation IB3 = IB1 - 3 + IB14 holds true. If it does not, there is a point of electricity theft between the third-level power acquisition device Fb3 and the fourth main power acquisition device Fa4. This further determines the specific location of the electricity theft point on the primary trunk line, accurately pinpointing its location.
