DETAILED DESCRIPTION

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. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the case where there is no conflict between the embodiments, the following embodiments and the features in the embodiments can be combined with each other. The steps in the following method embodiments are only used for exemplary description and are not intended to limit the present invention.

The current imbalance of the distribution transformer can easily lead to abnormal phenomena such as increased losses of the transformer and distribution lines, reduced active output of the motor, reduced transformer output, and damage to electrical equipment. Therefore, monitoring the unbalanced load state of each phase of the transformer is crucial to maintaining the optimal performance of the equipment and ensuring safe operation of the equipment.

The current mainstream multi-phase current balance state analysis chart mainly presents the balance state between multi-phase currents by drawing the current value change curve of each phase. However, the change curve type analysis chart cannot provide maintenance personnel with an intuitive understanding of the imbalance cycle of each phase, and there is a problem that the visual effect of the analysis chart is poor.

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 result 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.

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.

Method for expressing multiphase current balance state

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:

Step 102: Obtain current deviation values corresponding to each detection point for each phase according to single-phase current values corresponding to each detection point for each phase of the transformer.

In this embodiment, the transformer includes a distribution transformer, for example, a three-phase transformer, but this is not limited thereto, and other types of multi-phase transformers may be applicable to the present application.

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 each current detection value corresponding to each detection point of each phase.

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 to obtain 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.

In some embodiments, based on a preset value range, for each current detection value corresponding to each detection point of each phase, The normalization process is performed to obtain the single-phase current values of each phase corresponding to each detection point.

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.

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

For any current detection point among the detection points, the current average value of the current detection point is obtained according to the single-phase current value of each phase of the transformer corresponding to the current detection point, and the deviation calculation is performed according to 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.

Specifically, the average current value of the current detection point can be obtained by performing an addition and averaging calculation according to the single-phase current value of each phase of the transformer corresponding to the current detection point. The difference between each single-phase current value of the current detection point and the current average value of the current detection point is calculated to obtain the current difference between each phase of the current detection point and the current average value, and based on the absolute value of the current difference between each phase of the current detection point and the current detection point, the current deviation value of each phase corresponding to the current detection point is obtained.

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

In the above formula 1, _kij represents the current deviation value of the j-th phase of the transformer corresponding to the i-th detection point, _xij represents the single-phase current value of the j-th phase of the transformer corresponding to the i-th detection point, and _ui represents the current average value of the i-th detection point.

Step 104: Analyze the multiphase current balance state of each detection point according to each current deviation value corresponding to each detection point of each phase, and determine the balance state analysis mark of each detection point accordingly.

In some embodiments, for any current detection point among the detection points, the current deviation value corresponding to the current detection point of each phase can be compared with the preset balance threshold, and the phase whose current deviation value exceeds the preset balance threshold is determined as 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.

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 k _ij represents the current deviation value of the j-th phase of the transformer corresponding to the i-th detection point), the j-th phase is determined as the unbalanced phase of the i-th detection point.

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.

In some embodiments, if each phase of the current detection point contains only one unbalanced phase, the unbalanced phase can be directly The phase mark of the phase is determined as the equilibrium state analysis mark of the current detection point.

For example, in an embodiment of a three-phase transformer, if only the first phase is determined as the unbalanced phase of the current detection point, it means that the first phase has a current problem of too high or too low at the current detection point, then the phase identifier of the first phase is determined as the balanced state analysis identifier of the current detection point.

In some embodiments, if each phase of the current detection point includes 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 balanced state analysis identifier of the current detection point.

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 both the first phase and the second phase 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 balanced state analysis identifier of the current detection point.

In some embodiments, if each phase of the current detection point does not include an unbalanced phase, a given multi-phase equilibrium state identifier is determined as the equilibrium state analysis identifier of the current detection point.

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, and 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.

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

Exemplarily, color identifiers can be used to represent the phases of the three-phase transformer, wherein red can be used as the phase identifier of the first phase, yellow can be used as the phase identifier of the second phase, blue can be used as the phase identifier of the third phase, and gray can be used as the multi-phase balance state identifier. In this example, if the balance state analysis identifier of 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 identifier of 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 identifier of the current detection point is gray, it means that all phases of the current detection point are in a current balance state.

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.

Optionally, the same equilibrium state analysis mark or different equilibrium state analysis marks may be used to represent the multiphase equilibrium state mark and the data missing state mark. For example, the multiphase equilibrium state mark and the data missing state mark may both be set to gray.

Step 106: Generate a transformer multiphase current balance state representation diagram according to the balance state analysis mark of each detection point.

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

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.

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

Optionally, the detection date and detection time of each balance state analysis identifier can be determined according to the detection point of each balance state analysis identifier, and each balance state analysis identifier can be filled into the multi-phase current balance state heat map according to the detection date and detection time of each balance state analysis identifier and the horizontal axis coordinate and horizontal axis coordinate of the multi-phase current balance state heat map to generate a multi-phase current balance state heat map of the transformer.

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 unbalanced 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.

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.

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 according to 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.

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 marks each detection point with a different balance state analysis mark. 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 to improve the maintenance effect of the transformer.
