[0002] The current data of the knife switch during operation can intuitively reflect the operating state of the knife switch. Therefore, in order to monitor and process the current, in the invention patent application CN202110991712.4 "Monitoring and Alarm Method for Battery Pack Disconnection from DC Bus and Poor Contact", through the monitoring of the current, it is determined whether the voltage monitoring fuse, the knife switch is in poor contact, and whether the battery pack is disconnected from the DC bus, so as to determine whether there is a virtual connection phenomenon at the contact point.

[0003] However, through analysis, it is not difficult to find that once there is a problem with the contact of the knife switch during the ice melting process of the ice melting knife switch, it will inevitably affect the efficiency of the ice melting process of the transmission line. Therefore, how to specifically monitor and process the current data of the ice melting knife switch and ensure the reliability of the ice melting process has become a technical problem to be solved urgently.

[0032] Furthermore, the de-icing target line is a transmission line within a preset distance range from the mobile de-icing switch.

[0033] It can be understood that the historical icing data is the historical icing times of different de-icing target lines and the lengths of the de-icing target lines with icing conditions in different historical icing times.

[0034] Specifically, as Figure 3 shown, determining that the optimization process of the current monitoring method for the de-icing target line needs to be performed specifically includes: Based on the historical icing data of the de-icing target line, determine the historical icing times of different de-icing target lines; Based on the historical icing times of the de-icing target line in different unit time periods, determine the icing coincidence periods in the unit time periods; According to the number of the icing coincidence periods, determine whether the optimization process of the current monitoring method for the de-icing target line needs to be performed.

[0035] Further, the icing coincidence period in the unit period is the unit period in which the number of ice melting target lines with the historical icing times within the preset icing times range is greater than the preset target line number.

[0036] It should be noted that when the number of the icing coincidence periods is greater than the preset coincidence period number threshold, it is determined that the optimization process of the current monitoring method for the ice melting target line needs to be carried out.

[0037] It can be understood that when the optimization process of the current monitoring method for the ice melting target line is not required, during the maintenance period of the ice melting target line, the current monitoring process of the mobile ice melting disconnecting switch is carried out based on a fixed ice melting voltage.

[0038] In another possible embodiment, determining that the optimization process of the current monitoring method for the ice melting target line needs to be carried out specifically includes: Based on the historical icing data of the ice melting target line, determining the historical icing times of different ice melting target lines. When the total historical icing times of different ice melting target lines do not meet the requirements, it is determined that the optimization process of the current monitoring method for the ice melting target line needs to be carried out; When the total historical icing times of different ice melting target lines meet the requirements: Based on the historical icing times of different ice melting target lines, when it is determined that there is no ice melting target line with the historical icing times greater than the preset icing times threshold: Based on the historical icing times of the ice melting target lines in different unit periods, when it is determined that there is no icing coincidence period in the unit period, it is determined that the optimization process of the current monitoring method for the ice melting target line is not required; When there is an ice melting target line with the historical icing times greater than the preset icing times threshold or there is an icing coincidence period in the unit period: Taking the ice melting target line with the historical icing times greater than the preset icing times threshold as the risk target line.

[0039] Further, when the ice melting treatment risk coefficient is greater than the preset treatment risk coefficient threshold, it is determined that it is necessary to optimize the current monitoring method of the ice melting target line.

[0040] Specifically, the change situation of the ice melting current data includes the deviation amount of the ice melting current between different adjacent moments in different historical ice melting treatment times.

[0041] Specifically, as Figure 4 shown, the method for determining the set target line of the matching impedance of the ice melting target line is: Based on the change situation of the ice melting current data, determine the ice melting current of the mobile ice melting disconnect switch at different moments in different historical ice melting treatment times; Divide the historical ice melting treatment times with the deviation amount of the ice melting current at different moments within the preset current deviation amount range into the same ice melting treatment times group; According to the number of the ice melting treatment times groups and the historical ice melting treatment times, determine whether the ice melting target line is the set target line of the matching impedance.

[0043] It can be understood that when the ice melting target line does not belong to the set target line of the matching impedance, during the maintenance period of the ice melting target line, the current monitoring process of the mobile ice melting disconnect switch is carried out based on a fixed ice melting voltage.

[0044] In another possible embodiment, the method for determining the set target line of the matching impedance of the ice melting target line is: Obtain the historical ice melting treatment times of the ice melting target line. When the historical ice melting treatment times of the ice melting target line is greater than the preset treatment times threshold, determine that the ice melting target line is the set target line of the matching impedance; When the historical ice melting treatment times of the ice melting target line is not greater than the preset treatment times threshold: When the historical ice melting treatment times of the ice melting target line are within the preset ice melting treatment times interval, it is determined that the ice melting target line does not belong to the set target line for matching impedance; When the historical ice melting treatment times of the ice melting target line are not within the preset ice melting treatment times interval: Based on the change situation of the ice melting current data, determine the ice melting current of the mobile ice melting knife switch at different times in different historical ice melting treatment times, and divide the historical ice melting treatment times with the deviation amount of the ice melting current at different times within the preset current deviation amount interval into the same ice melting treatment times group. When the number of the ice melting treatment times groups does not meet the requirements, it is determined that the ice melting target line belongs to the set target line for matching impedance; When the number of the ice melting treatment times groups meets the requirements: Based on the historical ice melting treatment times in different ice melting treatment times groups, determine the distribution aggregation coefficient in different ice melting treatment times groups. When there is no ice melting treatment times group with a distribution aggregation coefficient greater than the preset aggregation coefficient threshold, it is determined that the ice melting target line does not belong to the set target line for matching impedance; When there is an ice melting treatment times group with a distribution aggregation coefficient greater than the preset aggregation coefficient threshold: Obtain the number of ice melting treatment times groups with a distribution aggregation coefficient greater than the preset aggregation coefficient threshold. When the number of ice melting treatment times groups with a distribution aggregation coefficient greater than the preset aggregation coefficient threshold does not meet the requirements, it is determined that the ice melting target line belongs to the set target line for matching impedance; When the number of ice melting treatment times groups with a distribution aggregation coefficient greater than the preset aggregation coefficient threshold meets the requirements: According to the distribution aggregation coefficient of different ice melting treatment times groups, determine the ice melting treatment change coefficient of the ice melting target line, and use the ice melting treatment change coefficient to determine whether the ice melting target line is the set target line for matching impedance.

[0045] Further, when the ice melting treatment change coefficient is greater than the preset change coefficient threshold, it is determined that the ice melting target line is the set target line for matching impedance.

[0046] It should be noted that the control process for the matching impedance specifically includes: Based on the change situation of the ice melting current data, determine the ice melting current of the mobile ice melting knife switch at different times in different historical ice melting treatment times; Divide the historical ice melting treatment times with the deviation amount of the ice melting current at different times within the preset current deviation amount interval into the same ice melting treatment times group; Take the de-icing treatment times group with the largest number of historical de-icing treatments as the target group. Determine the matching impedance values at different times under a fixed de-icing voltage according to the average values of the de-icing currents at different times for different historical de-icing treatment times in the target group, and use the matching impedance values to perform control processing on the matching impedance.

[0047] Further, the matching impedance value is the ratio of the de-icing voltage to the average value of the de-icing currents at different times.

[0048] It can be understood that the set current monitoring data of the target line includes the monitored currents of the mobile de-icing switch at different times.

[0049] Specifically, the method for determining the monitoring processing strategy of the current data during the later maintenance process of the set target line is as follows: Based on the analysis results of the current monitoring data in different set target lines, determine the deviation amounts between the current monitoring data and the reference current at different current monitoring times in different set target lines; Take the moments when the deviation amount from the reference current is greater than the preset current deviation amount as the current deviation moments, and determine the current deviation coefficients at different current monitoring times according to the proportion of the number of current deviation moments at different current monitoring times; According to the average values of the current deviation coefficients at different current monitoring times in different set target lines, determine the monitoring processing strategy of the current data during the later maintenance process of different set target lines.

[0050] Further, the method for determining the reference current is as follows: Based on the variation of the de-icing current data, determine the de-icing currents of the mobile de-icing switch at different times in different historical de-icing treatment times; Divide the historical de-icing treatment times in which the deviation amounts of the de-icing currents at different times are all within the preset current deviation amount range into the same de-icing treatment times group; Take the de-icing treatment times group with the largest number of historical de-icing treatments as the target group, and take the average values of the de-icing currents at different times for different historical de-icing treatment times in the target group as the reference currents at different times.

[0051] It should be noted that determining the monitoring processing strategy of the current data during the later maintenance process of different set target lines according to the average values of the current deviation coefficients at different current monitoring times in different set target lines specifically includes: The average value of the current deviation coefficients under different numbers of current monitoring is used as the reference deviation coefficient. When there is a set target line with a reference deviation coefficient greater than the preset deviation coefficient threshold: then the first monitoring and processing strategy is adopted to monitor and process the current data of different set target lines during the later maintenance process; When there is no set target line with a reference deviation coefficient greater than the preset deviation coefficient threshold: then the second monitoring and processing strategy is adopted to monitor and process the current data of different set target lines during the later maintenance process.

[0052] It can be understood that the method for determining the first monitoring and processing strategy is: Based on the change situation of the ice melting current data of the set target line, determine the ice melting current of the mobile ice melting knife switch at different times in different historical ice melting treatment times, and divide the historical ice melting treatment times with the deviation amounts of the ice melting current at different times all within the preset current deviation amount range into the same ice melting treatment times group; Based on the average values of the ice melting currents of different historical ice melting treatment times at different times in all the ice melting treatment times groups, perform control processing of the matching impedance and monitor and process the current data of the set target line.

[0053] Specifically, the method for determining the second monitoring and processing strategy is: Based on the change situation of the ice melting current data of the set target line, determine the ice melting current of the mobile ice melting knife switch at different times in different historical ice melting treatment times, and divide the historical ice melting treatment times with the deviation amounts of the ice melting current at different times all within the preset current deviation amount range into the same ice melting treatment times group; Take the ice melting treatment times group with the largest number of historical ice melting treatment times as the target group, determine the matching impedance values of the matching impedance at different times under the fixed ice melting voltage according to the average values of the ice melting currents of different historical ice melting treatment times in the target group, and use the matching impedance values to perform control processing on the matching impedance and monitor and process the current data of the set target line.

When the deviation amounts between the current monitoring data and the reference current of different set target lines under different current monitoring times all meet the requirements, the second monitoring and processing strategy is adopted to monitor and process the current data of different set target lines during later maintenance. When there are set target lines with deviation amounts between the current monitoring data and the reference current that do not meet the requirements under different current monitoring times, it proceeds to step S412; S412 takes the moments when the deviation amount from the reference current is greater than the preset current deviation amount as current deviation moments. When the number of current deviation moments does not meet the requirements for the current monitoring times, the first monitoring and processing strategy is adopted to monitor and process the current data of different set target lines during later maintenance. When there are no current monitoring times with the number of current deviation moments not meeting the requirements, it proceeds to step S413; S413 determines the current deviation coefficients of different current monitoring times based on the proportion of the number of current deviation moments and the deviation amount between the current deviation moments and the reference current at different current monitoring times.
