Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes the technical solution of the embodiment of the present invention in detail with reference to the specific embodiments of fig. 1 to 5. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic flow chart of a method for identifying an abnormal electricity consumer according to an embodiment of the present invention. As shown in fig. 1, the method provided in this embodiment includes:
specifically, as shown in fig. 2, the following embodiments are described by taking the branch circuit (shown in fig. 3) as an example, where the branch circuit is the same branch of a certain area topology structure, for example, 65 nodes, 75 nodes, siemens house, and siemens public toilet in the circuit, and 36 is a transformer of the branch.
Generally, voltage and current are collected in a power grid, and for use in subsequent charging and the like, branch voltage and branch current of a plurality of sampling points can be obtained, wherein each sampling point is a plurality of sampling moments within a preset duration range.
102, acquiring the change condition of a target parameter of a branch circuit based on the branch circuit voltage and the branch circuit current of each sampling point; the target parameter includes at least one of: voltage, current, impedance;
specifically, based on the branch voltage and the branch current at each sampling point, that is, the branch voltage and the branch current at a plurality of sampling moments, the change condition of the target parameter of the branch, for example, the information such as the change trend and the change amplitude of the voltage, the current or the impedance at different moments, is obtained.
And 103, determining whether an abnormal electricity user exists or not based on the change condition of the target parameter of the branch, and determining the position of the abnormal electricity user.
Specifically, the abnormal electricity consumption user mainly refers to a user who steals electricity in the embodiment of the invention, the change condition of the target parameter is generally stable and stable under the condition that the abnormal electricity consumption user does not exist, and if the abnormal electricity consumption user exists, the target parameter is abnormal, so that whether the abnormal electricity consumption user exists or not and the position of the abnormal electricity consumption user can be determined based on the change condition of the target parameter of the branch circuit. For example, the analysis is performed based on the change condition of the target parameter of each electricity consumer in the branch, for example, the target parameter is impedance, and in a normal condition, the change of the impedance of the branch is very small and can be considered as approximately constant, and if a large change suddenly occurs, an abnormal electricity consumer may exist.
In the method of the embodiment, the branch voltage and the branch current of a plurality of sampling points within a preset time range are obtained by aiming at any branch in the transformer area; acquiring the change condition of the target parameter of the branch based on the branch voltage and the branch current of each sampling point; the target parameter includes at least one of: voltage, current, impedance; and determining whether the abnormal electricity user exists or not and the position of the abnormal electricity user based on the change condition of the target parameter of the branch circuit, wherein the voltage and current data are easy to obtain, and the change conditions of the voltage, the current, the impedance and the like follow a certain rule, and if the abnormal electricity user does not exist, the rule is stable and unchangeable generally, so that the abnormal electricity user and the position of the abnormal electricity user can be more accurately determined.
Optionally, by analyzing the main circuit current, the working interval is identified, i.e. the range of the sampling instant is determined.
For example, when analyzing the main current curve of the branch in fig. 5, it is found that after the sampling time 37, all nodes have smaller currents than before, and can be considered to be in the non-operating state, so that the time period in the operating state at the sampling time 0-36 is taken for analysis, as shown in the dotted line box in fig. 7.
Alternatively, step 103 can be implemented in several ways:
mode 1:
determining whether the impedance of each sampling point of the branch circuit meets a preset condition or not based on the change condition of the target parameter of the branch circuit;
if the preset conditions are met, determining that the branch has abnormal electricity utilization users;
wherein the preset condition comprises at least one of the following conditions:
the difference value of the impedances of at least two sampling points is greater than or equal to a first preset threshold value;
the difference value of the maximum value and the minimum value in the impedance of each sampling point is greater than or equal to a second preset threshold value;
and the average value of the difference value of the impedance of each sampling point and the average impedance is greater than or equal to a third preset threshold value.
Optionally, for any sampling point, dividing the branch voltage of the sampling point by the branch current to obtain the impedance of the sampling point;
obtaining an impedance curve for representing the impedance change condition based on the impedance of each sampling point;
optionally, based on the impedance curve, determining whether the impedance of each sampling point meets a preset condition.
In particular, fig. 4 shows a voltage curve at a plurality of sampling instants of different nodes in the branch, and fig. 5 shows a current curve at a plurality of sampling instants of different nodes in the branch, respectivelyFrom the voltage and current curves of fig. 4 and 5, the nodes under the branch can be obtained in the operating region
The curve, for example, the impedance curve at node 75 in fig. 6.
Optionally, for any user position (such as a power utilization node) in the branch, determining whether the impedance of each sampling point at the user position meets the preset condition based on the change condition of the target parameter at the user position;
and if the impedance of each sampling point at least one user position meets the preset condition, determining at least one user position as the position of the abnormal electricity user.
(1) When each power utilization node does not have an abnormal power utilization user, the voltage drop of each power utilization node changes:
then
Should remain constant throughout;
namely that
The curve change should be close to a horizontal line, as shown in the dashed box in fig. 8;
when an unrecognized abnormal electricity user exists under the node,
the variation curve is shown in fig. 9.
Alternatively, whether the impedance meets the preset condition may be determined by determining whether a difference between the maximum value and the minimum value of the impedance of each sampling point is greater than or equal to a second preset threshold.
Specifically, if the difference between the maximum value and the minimum value in the impedance of each sampling point is greater than or equal to the second preset threshold, it indicates that the fluctuation of the impedance of each sampling point is large, and an abnormal electricity consumer may exist.
Alternatively, determining whether the average value of the difference between the impedance of each sampling point and the average impedance is greater than or equal to a third preset threshold may be implemented by the following formula:
wherein,
the number of the sampling points is,
is a third preset threshold value, and is,
is as followsiThe impedance of the individual sampling points is,
is the average impedance of the branch.
When the temperature is higher than the set temperature
And if so, judging that the abnormal electricity utilization user exists.
In the above embodiment, whether the impedance of each sampling point meets the preset condition can be determined, so that whether an abnormal power utilization user exists can be determined accurately, and the implementation complexity is low.
Mode 2:
determining whether the branch voltage and the branch current of each sampling point have positive correlation based on the change condition of the target parameter of the branch;
and if the branch does not have positive correlation, determining that the branch has the abnormal electricity utilization user.
Optionally, for any user position (such as a power utilization node) in the branch circuit, based on a change condition of a target parameter at the user position, determining whether a branch circuit voltage and a branch circuit current of each sampling point at the user position have a positive correlation;
and if the branch voltage and the branch current of each sampling point at least one user position do not have positive correlation, determining at least one user position as the position of the abnormal electricity user.
Specifically, the voltage drop change formula of each power consumption node under the branch is as follows:
hence, the voltage drop at each point on the branch
The change is mainly composed of
Caused by, and impedance
Mainly related to the length of the line, normally the impedance
The variation is small and can be regarded as quantitative. Therefore, the voltage drop change of each node on the branch is mainly changed by the main circuit current before the node
Caused by a pressure drop
With main circuit current variation
Is a positive correlation, i.e.:
therefore, when the unmetered abnormal electricity user does not exist, the branch circuit voltage
And branch current
Should exhibit a strong positive correlation therebetween.
Thus, the branch voltage can be passed
And branch current
The correlation between the branch voltage and the voltage of the branch circuit determines whether an abnormal electricity user exists or not, namely when the abnormal electricity user does not exist
And branch current
Should exhibit a strong positive correlation therebetween; branch circuit voltage when unmetered abnormal electricity user exists
And branch current
Have poor positive correlation.
Optionally, determining whether the branch voltage and the branch current of each sampling point have a direct proportional relationship based on the change condition of the target parameter of the branch;
and if the branch circuit does not have the direct proportional relation, determining that the abnormal electricity utilization user exists in the branch circuit.
Specifically, the positive correlation may be, for example, a direct proportional relationship, which is a specific example of the positive correlation.
If the direct proportional relation exists, the abnormal electricity utilization user does not exist.
In the above embodiment, by determining whether the branch voltage and the branch current of each sampling point have positive correlation, whether an abnormal power consumption user exists can be accurately determined, and the implementation complexity is low.
