[0002] Distribution transformers are the main power supply equipment for low-voltage power grids. Since most low-voltage distribution systems use a three-phase four-wire wiring method, it is easy to cause single-phase load imbalance problems.

[0003] Specifically, current imbalance in three-phase transformers is primarily caused by factors such as unequal impedance in the distribution system or unequal loads on the three phases of the transformer. If a distribution transformer operates in a state of three-phase imbalance for a long period of time, it can lead to increased losses in the transformer and distribution lines, reduced active power output of motors and transformers, and damage to electrical equipment. Therefore, monitoring and correcting transformer phase load imbalance is crucial for achieving optimal equipment performance and ensuring safe operation.

[0017] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field should fall within the scope of protection of the embodiments of the present application.

[0018] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. The following embodiments and features thereof may be combined with one another unless they conflict with each other. The steps in the following method embodiments are for illustrative purposes only and are not intended to limit the present invention.

[0019] Current imbalance in distribution transformers can easily lead to increased losses in the transformer and distribution lines, reduced motor and transformer output, and damage to electrical equipment. Therefore, monitoring the load imbalance between each phase of the transformer is crucial to maintaining optimal equipment performance and ensuring safe operation.

[0020] Current mainstream multiphase current balance analysis charts primarily depict the current balance status of multiple phases by plotting the current value variation curves for each phase. However, these curve-based analysis charts fail to provide maintenance personnel with an intuitive understanding of the imbalance cycle for each phase, resulting in poor visualization.

[0021] Based on this, each embodiment of the present application provides a multi-phase current balance state representation scheme, which determines the balance state analysis identifier of each detection point according to the unbalanced phase analysis results of each detection point, and can clearly and intuitively display the unbalanced cycle of each phase, improve the visualization effect of the analysis chart, and improve equipment maintenance efficiency.

[0022] The following describes in detail the multi-phase current balance state representation method, device, electronic device and storage medium provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0023] Method for expressing multiphase current balance state

[0024] FIG1 is a flow chart of a method for representing a multi-phase current balance state according to an exemplary embodiment of the present application. As shown in FIG1 , the method for representing a multi-phase current balance state according to the present embodiment mainly includes the following steps:

[0025] Step 102: Obtain current deviation values ​​corresponding to each detection point in each phase according to each single-phase current value corresponding to each detection point in each phase of the transformer.

[0026] In this embodiment, the transformer includes a distribution transformer, such as a three-phase transformer, but is not limited thereto, and other types of multi-phase transformers are also applicable to this application.

[0027] In some embodiments, the single-phase current of each phase of the transformer may be detected based on a preset detection interval time to obtain current detection values ​​corresponding to detection points of each phase.

[0028] Taking a three-phase transformer as an example, when the preset detection interval is set to 15 minutes, the single-phase currents corresponding to the first phase, second phase, and third phase of the three-phase transformer can be detected every 15 minutes, and the first-phase current detection value, second-phase current detection value, and third-phase current detection value of the three-phase transformer corresponding to each detection point can be obtained.

[0029] In some embodiments, a normalization process may be performed on each current detection value corresponding to each detection point of each phase based on a preset value range to obtain each single-phase current value corresponding to each detection point of each phase.

[0030] For example, when the preset value range is set to [0,1], normalized data preprocessing can be performed on the first-phase current detection value, second-phase current detection value, and third-phase current detection value corresponding to each detection point of the three-phase transformer, so that the current detection values ​​of each phase corresponding to each detection point are limited to the value range of 0 to 1, and the single-phase current values ​​(first-phase current value, second-phase current value, third-phase current value) of each phase corresponding to each detection point are obtained.

[0031] In some embodiments, the current deviation values ​​of each phase corresponding to each detection point can be obtained by:

[0032] For any current detection point among the detection points, the current average value of the current detection point is obtained based on the single-phase current value of each phase of the transformer corresponding to the current detection point, and the deviation calculation is performed based on the single-phase current value of each phase corresponding to the current detection point and the current average value of the current detection point to obtain the current deviation value of each phase corresponding to the current detection point.

[0033] Specifically, an addition and averaging calculation can be performed based on the single-phase current value of each phase of the transformer corresponding to the current detection point to obtain the average current value at the current detection point. A difference calculation is performed between each single-phase current value at the current detection point and the average current value at the current detection point to obtain the current difference between each phase at the current detection point and the average current value. Based on the absolute value of the current difference between each phase at the current detection point and the current detection point, a current deviation value corresponding to the current detection point is obtained for each phase.

[0034] In some embodiments, the current deviation value of each phase corresponding to the current detection point can be calculated using the following formula 1: ij =|(x ij -u i ) / u i | (Formula 1)

[0035] In the above formula 1, k ij Indicates the current deviation value of the j-th phase of the transformer corresponding to the i-th detection point, x ij Indicates the single-phase current value of the transformer's j-th phase corresponding to the i-th detection point, u i Represents the average current value of the i-th detection point.

[0036] Step 104 : Analyze the multi-phase current balance state of each detection point according to each current deviation value corresponding to each detection point in each phase, and determine a balance state analysis identifier of each detection point accordingly.

[0037] In some embodiments, for any current detection point among the detection points, the current deviation value corresponding to each phase of the current detection point can be compared with a preset balance threshold, and the phase whose current deviation value exceeds the preset balance threshold is determined to be the unbalanced phase of the current detection point, and based on the unbalanced phase among the phases of the current detection point, a balance state analysis identifier of the current detection point is generated.

[0038] In this embodiment, the preset balance threshold can be set to 0.4. When the current deviation value of any phase corresponding to the current detection point is greater than the preset balance threshold, that is, k ij >0.4 (where kij represents the current deviation value of the j-th phase of the transformer corresponding to the i-th detection point), and the j-th phase is determined as the unbalanced phase of the i-th detection point.

[0039] It should be noted that those skilled in the art can arbitrarily set the preset balance threshold based on actual analysis requirements, application scenarios of the transformer and other factors, and this application does not impose any restrictions on this.

[0040] In some embodiments, if the phases of the current detection point include only one unbalanced phase, the phase identifier of the unbalanced phase may be directly determined as the balance state analysis identifier of the current detection point.

[0041] For example, in an embodiment of a three-phase transformer, if only the first phase is determined to be the unbalanced phase at the current detection point, indicating that the first phase has a current problem of being too high or too low at the current detection point, the phase identifier of the first phase is determined as the balance state analysis identifier of the current detection point.

[0042] In some embodiments, if the phases of the current detection point include multiple unbalanced phases, the current deviation values ​​corresponding to the unbalanced phases can be compared, and the phase identifier of the unbalanced phase with the largest current deviation value can be determined as the balance state analysis identifier of the current detection point.

[0043] For example, in an embodiment of a three-phase transformer, if the first phase and the second phase are both determined to be unbalanced phases at the current detection point, it means that the first phase and the second phase both have problems of too high or too low current at the current detection point. In this case, the current deviation values ​​of the first phase and the second phase can be compared, and the phase identifier of the phase with a larger current deviation value (for example, the first phase) can be determined as the balance state analysis identifier of the current detection point.

[0044] In some embodiments, if the phases of the current detection point do not include an unbalanced phase, the given multi-phase equilibrium state identifier is determined as the equilibrium state analysis identifier of the current detection point.

[0045] For example, in an embodiment of a three-phase transformer, if the current deviation value of each phase at the current detection point is within the normal range, it means that the three phases of the transformer are in a normal balanced state at the current detection point. The multi-phase balance state identifier used to indicate that each phase is in a normal balanced state can be determined as the balance state analysis identifier of the current detection point.

[0046] In some embodiments, the equilibrium state analysis mark may include one of a color mark and a graphic mark.

[0047] For example, color codes can be used to represent the phases of a three-phase transformer, where red can be used as the phase code for the first phase, yellow can be used as the phase code for the second phase, blue can be used as the phase code for the third phase, and gray can be used as the multi-phase balance state code. In this example, if the balance state analysis code for the current detection point is red, it means that there is a current imbalance problem in the first phase at the current detection point; if the balance state analysis code for the current detection point is yellow, it means that there is a current imbalance problem in the second phase at the current detection point; if the balance state analysis code for the current detection point is gray, it means that all phases at the current detection point are in a current balanced state.

[0048] In some embodiments, if the single-phase current value corresponding to the current detection point of each phase of the transformer is missing, for example, if the single-phase current value corresponding to the current detection point of each phase of the transformer cannot be detected, the given data missing state identifier can be determined as the balance state analysis identifier of the current detection point.

[0049] Alternatively, the same equilibrium state analysis identifier or different equilibrium state analysis identifiers may be used to represent the multiphase equilibrium state identifier and the data missing state identifier. For example, the multiphase equilibrium state identifier and the data missing state identifier may both be set to gray.

[0050] Step 106: Generate a transformer multi-phase current balance state representation diagram based on the balance state analysis identifier of each detection point.

[0051] In some embodiments, the multi-phase current balance state representation may include a multi-phase current balance state heat map.

[0052] Optionally, the horizontal axis coordinate and the horizontal axis coordinate of the multi-phase current balance state heat map may be determined according to the detection date and the detection time of each detection point.

[0053] Referring to Figure 2, the horizontal axis coordinates of the multiphase current balance state heat map can be determined based on the test date of the test point. For example, if "day" is used as the scale unit of the horizontal axis and the test time is 365 days, the horizontal axis of the multiphase current balance state heat map should have 365 horizontal coordinates. The vertical axis coordinates of the multiphase current balance state heat map can be determined based on the test interval of the test point. For example, if the test interval is set to 15 minutes, there should be 96 test points per day, and the vertical axis of the multiphase current balance state heat map should have 96 vertical coordinates.

[0054] Optionally, the detection date and detection time of each balance state analysis identifier can be determined based on the detection point of each balance state analysis identifier, and each balance state analysis identifier can be filled into the multiphase current balance state heat map based on the detection date and detection time of each balance state analysis identifier and the horizontal axis coordinate and horizontal axis coordinate of the multiphase current balance state heat map to generate a multiphase current balance state heat map of the transformer.

[0055] The multi-phase current balance state representation scheme provided in the embodiment of the present application analyzes the multi-phase current balance state of each detection point, determines the balance state analysis identifier of each detection point, and generates a multi-phase current balance state representation diagram of the transformer corresponding to each detection point based on the balance state analysis identifier of each detection point. In this way, the present application can intuitively and clearly display the unbalance cycle of each phase in the transformer, improve the visual effect of the multi-phase current balance state analysis diagram, effectively reduce energy loss, and extend the service life of the transformer.

[0056] The multi-phase current balance state representation scheme provided in the embodiment of the present application performs normalization processing on each current detection value corresponding to each detection point of each phase, so that each current detection value corresponding to each detection point of each phase is limited to a preset value range, thereby improving the accuracy of the multi-phase current balance state analysis results.

[0057] The multi-phase current balance state representation scheme provided in the embodiment of the present application calculates the current average value of each detection point based on the single-phase current value of each detection point corresponding to each phase, and dynamically calculates the current deviation value of each phase corresponding to each detection point based on the current average value of each detection point, thereby improving the objectivity and accuracy of the multi-phase current balance state analysis results.

[0058] The multi-phase current balance state representation scheme provided in the embodiment of the present application analyzes the unbalanced phase in each detection point and identifies each detection point with a different balance state analysis identifier. This allows management personnel to intuitively and clearly understand the unbalanced distribution cycle of each phase in the transformer, and provide a more accurate transformer maintenance plan, thereby improving the maintenance effect of the transformer.
