[0002] Multi-break circuit breakers are crucial equipment in power transmission systems, and their reliability directly impacts the safe and stable operation of the power grid. During long-term operation, mechanical wear and other factors can amplify the differences between the different breaks, leading to uneven voltage distribution between parallel ports. This, in turn, causes errors in the synchronization of breaking operations, ultimately resulting in significant delays in the breaking relationship between the breaks, and even errors where the breaking relationship is reversed. Consequently, this affects the stable operation of the power transmission system and load distribution. Summary of the Invention

[0017] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0018] It should be noted that the acquisition, transmission, storage, use, and processing of data in the technical solution of this application all comply with relevant laws and regulations. In the embodiments of this application, certain existing industry solutions such as software, components, and models may be mentioned.

[0019] like Figure 1 This is a flowchart of a state correction method for a multi-break circuit breaker according to an embodiment of the present invention. Figure 1 In this method, the steps may include: In step S10, the historical change status value of each break of the multi-break circuit breaker is obtained; In step S11, the historical change state values ​​of every two fracture surfaces are correlated; In step S12, the corresponding synchronization rate is calculated based on the associated historical change state values; In step S13, the correlation between every two breaks is determined based on the synchronization rate; In step S14, the current status of the multi-break circuit breaker is obtained; In step S15, the state is corrected based on the correlation.

[0020] In the method shown in Figure 1, step S10 can be used to obtain the historical change state value of each port of the multi-break circuit breaker. Specifically, in step S10, each break can be numbered first, and then the state data of the break can be cleaned and filtered to remove interference items. To facilitate subsequent processing, step S10 can also generate each point value in the historical change state value with the minimum time interval of the state change of the break as the time period, and finally generate a matrix representation of the historical change state value according to the time series. In an example of the present invention, the data format of the historical change state value can be, for example, as shown in Table 1 below: Table 1: Partial Examples of Historical Change Values

[0021] Step S11 may involve associating the historical change state values ​​of every two fracture points. Specifically, step S11 may involve sequentially selecting every two fracture points to associate them, forming a fracture point group. Correspondingly, the historical change state value of this fracture point group is a combination of two historical change state values.

[0022] Step S12 can be based on calculating the corresponding synchronization rate according to the associated historical change state values. This synchronization rate can be used to represent the similarity of changes in the historical change state values ​​of the two associated breaks. The specific calculation method for this synchronization rate can be of various forms known to those skilled in the art. In one example of the present invention, to reduce the complexity of the algorithm, it can be done using methods such as... Figure 2 The method shown is used to calculate this synchronization rate. Specifically, in this... Figure 2 In this context, the method for calculating the synchronization rate may include the following steps: In step S20, a segment of historical change state values ​​after association is extracted in chronological order to serve as a calibration synchronization segment; In step S21, the segmented synchronization rate of the calibration synchronization segment is calculated; In step S22, it is determined whether the segmented synchronization rate is greater than or equal to the preset segmented synchronization rate threshold. In step S23, if it is determined that the segmented synchronization rate is greater than or equal to the segmented synchronization rate threshold, the remaining historical change state value is detected by using the segmented synchronization rate of the calibrated synchronization segment. In step S24, it is determined whether the remaining historical change state values ​​have passed the detection; In step S25, if the historical change state value detection passes, the segmented synchronization rate is used as the synchronization rate.

[0023] In step S26, if the historical change state value detection fails, the location of the current failed detection is determined; In step S27, it is determined whether the distance between the location and the captured historical change state value is greater than or equal to a preset distance threshold. In step S28, if the distance between the location and the intercepted historical change state value is greater than or equal to the distance threshold, the location is taken as the initial point, and the process returns to execute the step of intercepting a segment of associated historical change state values ​​in chronological order as a calibration synchronization segment, that is, returning to execute step S20. If the distance between the determined location and the intercepted historical change state value is less than the distance threshold, return to the step of intercepting a segment of associated historical change state values ​​in chronological order as a calibration synchronization segment, that is, return to the step of executing step S20.

[0024] In such Figure 2In the method shown, step S20 is used to extract a segment of correlated historical change state values ​​in chronological order as a calibration synchronization segment. Since the correlated historical change state values ​​are two sequences of the same length, determining their correlation requires comparing these two sequences one by one. Considering the large computational load required for direct comparison of the entire sequence, and the fact that load allocation strategies in power transmission systems differ across time periods, a comprehensive analysis approach cannot be directly used to determine the correlation. Therefore, in this example, step S20 is used to extract a segment for analysis, yielding a preliminary correlation, i.e., the segmented synchronization rate. Steps S21 and S22 are used to check whether the extracted historical change state values ​​yield a valid correlation. If the corresponding segmented synchronization rate is low, the correlation is obviously invalid. If the segmented synchronization rate is greater than or equal to the segmented synchronization rate threshold, the obtained correlation is valid, and steps S23 and S24 can be used for comprehensive detection. If the comprehensive detection is successful, it indicates a high correlation between the two historical change state values, and therefore the segmented synchronization rate can be directly used as the synchronization rate. Conversely, this indicates that the synchronization rates of the two historical change state values ​​differ at different times, thus requiring further segmented analysis via steps S26 to S28. Furthermore, regarding the specific calculation method for the segmented synchronization rate, in one example of this invention, it can be as follows: first, count the number of points with the same and different states in the calibrated synchronization segment; then, calculate the ratio of the larger of the number of points with the same and different states to the total number; finally, use this ratio as the segmented synchronization rate.

[0025] Step S23 can be used to detect the remaining historical change state values ​​using the segmented synchronization rate of the calibrated synchronization segment. Specifically, step S23 can be used to detect the point values ​​of the historical change state values ​​one by one using the correlation corresponding to the segmented synchronization rate, and determine the proportion of the number of point value pairs that satisfy the correlation to the total number of corresponding points. If the proportion is greater than a preset value, the detection is considered successful; otherwise, the detection is considered unsuccessful.

[0026] On the other hand, the present invention also provides a condition correction system for multi-break circuit breakers, such as... Figure 3 As shown, the calibration system may include a relay controller 1 and a status monitoring server 2. The relay controller can be used to control the status of each break of a multi-break circuit breaker to perform calibration operations. The status monitoring server can be used to perform actions such as... Figure 1 and Figure 2 The method shown. Specifically, the status monitoring server 2 can be used for: In step S10, the historical change status value of each break of the multi-break circuit breaker is obtained; In step S11, the historical change state values ​​of every two fracture surfaces are correlated; In step S12, the corresponding synchronization rate is calculated based on the associated historical change state values; In step S13, the correlation between every two breaks is determined based on the synchronization rate; In step S14, the current status of the multi-break circuit breaker is obtained; In step S15, the state is corrected based on the correlation.

[0027] In the method shown in Figure 1, step S10 can be used to obtain the historical change state value of each port of the multi-break circuit breaker. Specifically, in step S10, each break can be numbered first, and then the state data of the break can be cleaned and filtered to remove interference items. To facilitate subsequent processing, step S10 can also generate each point value in the historical change state value with the minimum time interval of the state change of the break as the time period, and finally generate a matrix representation of the historical change state value according to the time series. In an example of the present invention, the data format of the historical change state value can be, for example, as shown in Table 1 below: Table 1: Partial Examples of Historical Change Values

[0028] Step S11 may involve associating the historical change state values ​​of every two fracture points. Specifically, step S11 may involve sequentially selecting every two fracture points to associate them, forming a fracture point group. Correspondingly, the historical change state value of this fracture point group is a combination of two historical change state values.

[0029] Step S12 can be based on calculating the corresponding synchronization rate according to the associated historical change state values. This synchronization rate can be used to represent the similarity of changes in the historical change state values ​​of the two associated breaks. The specific calculation method for this synchronization rate can be of various forms known to those skilled in the art. In one example of the present invention, to reduce the complexity of the algorithm, it can be done using methods such as... Figure 2 The method shown is used to calculate this synchronization rate. Specifically, in this... Figure 2 In this context, the method for calculating the synchronization rate may include the following steps: In step S20, a segment of historical change state values ​​after association is extracted in chronological order to serve as a calibration synchronization segment; In step S21, the segmented synchronization rate of the calibration synchronization segment is calculated; In step S22, it is determined whether the segmented synchronization rate is greater than or equal to the preset segmented synchronization rate threshold. In step S23, if it is determined that the segmented synchronization rate is greater than or equal to the segmented synchronization rate threshold, the remaining historical change state value is detected by using the segmented synchronization rate of the calibrated synchronization segment. In step S24, it is determined whether the remaining historical change state values ​​have passed the detection; In step S25, if the historical change state value detection passes, the segmented synchronization rate is used as the synchronization rate.

[0030] In step S26, if the historical change state value detection fails, the location of the current failed detection is determined; In step S27, it is determined whether the distance between the location and the captured historical change state value is greater than or equal to a preset distance threshold. In step S28, if the distance between the location and the intercepted historical change state value is greater than or equal to the distance threshold, the location is taken as the initial point, and the process returns to execute the step of intercepting a segment of associated historical change state values ​​in chronological order as a calibration synchronization segment, that is, returning to execute step S20. If the distance between the determined location and the intercepted historical change state value is less than the distance threshold, return to the step of intercepting a segment of associated historical change state values ​​in chronological order as a calibration synchronization segment, that is, return to the step of executing step S20.

[0031] In such Figure 2In the method shown, step S20 is used to extract a segment of correlated historical change state values ​​in chronological order as a calibration synchronization segment. Since the correlated historical change state values ​​are two sequences of the same length, determining their correlation requires comparing these two sequences one by one. Considering the large computational load required for direct comparison of the entire sequence, and the fact that load allocation strategies in power transmission systems differ across time periods, a comprehensive analysis approach cannot be directly used to determine the correlation. Therefore, in this example, step S20 is used to extract a segment for analysis, yielding a preliminary correlation, i.e., the segmented synchronization rate.

If the corresponding segmented synchronization rate is low, the correlation is obviously invalid. If the segmented synchronization rate is greater than or equal to the segmented synchronization rate threshold, the obtained correlation is valid, and steps S23 and S24 can be used for comprehensive detection. If the comprehensive detection is successful, it indicates a high correlation between the two historical change state values, and therefore the segmented synchronization rate can be directly used as the synchronization rate. Conversely, this indicates that the synchronization rates of the two historical change state values ​​differ at different times, thus requiring further segmented analysis via steps S26 to S28. Furthermore, regarding the specific calculation method for the segmented synchronization rate, in one example of this invention, it can be as follows: first, count the number of points with the same and different states in the calibrated synchronization segment; then, calculate the ratio of the larger of the number of points with the same and different states to the total number; finally, use this ratio as the segmented synchronization rate.

[0032] Step S23 can be used to detect the remaining historical change state values ​​using the segmented synchronization rate of the calibrated synchronization segment. Specifically, step S23 can be used to detect the point values ​​of the historical change state values ​​one by one using the correlation corresponding to the segmented synchronization rate, and determine the proportion of the number of point value pairs that satisfy the correlation to the total number of corresponding points. If the proportion is greater than a preset value, the detection is considered successful; otherwise, the detection is considered unsuccessful.

[0033] Through the above technical solution, the embodiments of the present invention provide a state correction method and system for multi-break circuit breakers. This method and system determine the correlation by combining historical state change values ​​of the multi-break circuit breaker with the synchronization rate between the breaks, thereby achieving automatic state correction of the multi-break circuit breaker.
