Description

Technical Field

[0001] The invention relates to the technical field of line interference, in particular to a system for regulating the distance between phase conductors. Background Art

[0002] Live pole removal or erection is a high-risk operation that requires the removal or erection of poles without cutting off the power supply. During the live operation, the distance between the phase-to-phase conductors associated with the original pole needs to be readjusted to identify whether there is relevant electromagnetic interference between the phase-to-phase conductors, so as to control and adjust the distance.

[0003] During live working, the conductors are usually sorted again based on their original sorting method and surface debris is cleaned without considering whether there has been relevant electromagnetic interference between the conductors in the past period of time, nor is the distance between the phase conductors adjusted based on the specific electromagnetic interference situation, thus failing to obtain a better anti-interference effect. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a system for adjusting the distance between phase conductors, which solves the problem of not considering whether there is relevant electromagnetic interference between the conductors in the past time period and not adjusting the distance between the phase conductors based on the specific electromagnetic interference situation.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A system for adjusting the distance between phase conductors, comprising:

[0006] The data monitoring end periodically monitors the interphase conductors associated with the location where the live pole is removed. The monitored power parameter is the power parameter, and the power parameters of different interphase conductors monitored at different times are transmitted to the data analysis end, and the set period is a preset period;

[0007] The data analysis end performs relevant verification on different power parameters monitored by different phase-to-phase conductors at different times in the cycle, identifies whether the corresponding phase-to-phase conductor is a fluctuating conductor, and determines the fluctuating period of the corresponding fluctuating conductor. The specific method is as follows:

[0008] The different power parameters monitored by different phase conductors at different times in this cycle are calibrated as G i-k , where i represents different moments, k represents different phase-to-phase conductors, and the calibrated different power parameters G i-k Compare with the preset range, where the endpoint values ​​of the preset range are the preset values:

[0009] when When the power parameter is within the preset range, the power parameter is marked as abnormal power, and the abnormal time corresponding to the abnormal power is recorded. When the abnormal power appears continuously after the abnormal time, the abnormal duration is recorded. If the abnormal duration is ≥5min, the specific abnormal period is recorded, the phase-to-phase conductor is marked as a fluctuating conductor, and the abnormal period is marked as the fluctuating period of the fluctuating conductor. The determined fluctuating conductor and the related fluctuating period are transmitted to the line calibration terminal;

[0010] When G i-k ∈ preset range, no processing is performed;

[0011] The line calibration end, based on the determined fluctuating conductors and the related fluctuating periods, identifies whether the fluctuating periods between the fluctuating conductors are crossed, and based on the specific results identified, confirms and marks the interfering conductors, specifically in the following manner:

[0012] Confirm the fluctuation periods of the different fluctuation wires one by one, and identify whether there are intersecting periods between the fluctuation periods of the different fluctuation wires. If there are fluctuation periods with intersecting periods, mark such fluctuation periods as the periods to be processed and put them in a processing set. If there are no fluctuation periods with intersecting periods, no marking is performed.

[0013] Confirm the crossover periods of the waiting-for-processing time periods in the processing set: randomly select a group of waiting-for-processing time periods as the main time periods, and confirm the crossover periods between the main time periods and other waiting-for-processing time periods. If there is a group of crossover time periods with a total duration exceeding 2 minutes among several groups of crossover time periods, the fluctuation wire corresponding to this main time period will be marked as an interference wire. If the total duration does not exceed 2 minutes, no relevant marking will be performed.

[0014] Then determine the main time period from other time periods to be processed in turn, confirm the intersecting time periods of the main time period and other time periods to be processed, and process them one by one, and confirm the interfering wires associated with this processing set one by one;

[0015] The confirmed interference wires are displayed through the display terminal;

[0016] The data processing end receives the relevant monitoring data during the conductor adjustment process, and performs relevant analysis on the received relevant power parameters. The power parameter changes between each different conductor are confirmed through the associated data analysis unit, and the approved value is locked. The determined approved value is transmitted to the adjustment mode determination unit. The adjustment mode determination unit selects the best adjustment mode based on the determined groups of different approved values ​​and displays it.

[0017] The specific method for the associated data analysis unit to lock its approved value is:

[0018] The power parameters of different conductors monitored during the adjustment process are confirmed, and a power parameter change curve of the related conductors is generated, so the horizontal coordinate axis of the change curve is the time line, and the vertical coordinate axis is the power parameter;

[0019] From a number of power parameter change curves generated in real time, the line segments belonging to the preset range are marked as standard segments, and from a number of power parameter change curves, the relevant standard segments that appear synchronously in the same period are confirmed, and such time periods are marked as optimal time periods;

[0020] Based on the confirmed optimal period, the standard sections associated with the optimal period are analyzed, and the difference in power parameters between adjacent nodes is determined from each group of standard sections, where the difference = the power parameter of the next node minus the power parameter of the previous node. The maximum value of the difference is selected from the determined differences as the standard value of the current standard section.

[0021] The standard values ​​of several standard sections corresponding to this optimal period are averaged to determine the approved value H q , where q represents different optimal time periods;

[0022] The adjustment mode determination unit is based on different approved values ​​H determined for each different optimal time period. q , from several approved values ​​H q A set of minimum values ​​is selected, the best time period corresponding to the minimum value is marked as the standard optimal time period, and the adjustment record associated with the standard optimal time period is searched and determined.

[0023] Preferably, the display end displays the confirmed interfering wires one by one for external relevant personnel to view and make relevant adjustments.

[0024] Preferably, the display terminal displays the determined adjustment record.

[0025] The present invention provides a system for adjusting the distance between phase conductors. Compared with the prior art, the present invention has the following advantages:

[0026] Beneficial effects:

[0027] The present invention monitors the data of the associated wires at the location where the live pole is removed, and based on the relevant specific monitoring results, performs relevant analysis on the numerical fluctuation of the relevant fluctuating wires to identify whether the fluctuating wires interfere with each other, thereby locking the interfering wires. In the subsequent wire distance adjustment process, the locked interfering wires are preferentially adjusted in distance, which is convenient for the distance control work of the relevant personnel, and timely processing is performed to achieve a better wire distance adjustment effect.

[0028] During the distance adjustment process of the phase-to-phase conductors, the relevant power fluctuation parameters are determined for each different adjustment process, and then the best relevant segments and the best time periods are determined based on the specific performance of the power fluctuation parameters. The best time periods are then analyzed and confirmed, and the best adjustment records are locked and displayed, so as to achieve the best conductor distance adjustment effect, avoid mutual interference between conductors, and minimize the interference.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figure 1 , the present application provides a phase-to-phase conductor distance adjustment system, including a data monitoring terminal, a data analysis terminal, a line calibration terminal, a data processing terminal and a display terminal, wherein the data monitoring terminal is electrically connected to the input node of the data analysis terminal or the data processing terminal, and the data analysis terminal is electrically connected to the input node of the line calibration terminal, and the line calibration terminal and the data processing terminal are both electrically connected to the input node of the display terminal;

[0034] The data processing end includes a correlation data analysis unit and an adjustment mode determination unit, wherein the correlation data analysis unit is electrically connected to an input node of the adjustment mode determination unit;

[0035] Among them, the data monitoring end performs periodic monitoring on the interphase conductors associated with the location of the live pole removal. The monitored power parameter is the power parameter, and the power parameters of different interphase conductors monitored at different times are transmitted to the data analysis end. The set period is a preset period, which is prepared in advance by relevant operators based on experience, and generally takes a value of 50 minutes. Specifically, the location of the live pole removal is determined in advance by relevant personnel. When some areas need to adjust the live pole removal, it needs to be determined in advance according to the regional conditions. When performing numerical monitoring, it belongs to the live operation process, and the relevant operators need to wear relevant insulating clothes in advance to lay sensors and monitor the power parameters of each interphase conductor.

[0036] Among them, the data analysis end performs relevant verification on different power parameters monitored by different phase-to-phase conductors at different times in the cycle, identifies whether the corresponding phase-to-phase conductor is a fluctuating conductor, and determines the fluctuation period of the corresponding fluctuating conductor. Since the relevant adjustment is mainly made for the power interference between the phase-to-phase conductors, it is necessary to confirm the associated conductors with interference, lock the associated conductors with numerical fluctuations, and adjust the gap distance between such related conductors in the subsequent relevant adjustment process to achieve a better overall adjustment effect and minimize the mutual interference between the conductors. Among them, the specific method of determining the fluctuation period is:

[0037] Combination Figure 2 , the different power parameters monitored by different phase conductors at different times in this cycle are calibrated as G i-k , where i represents different moments, k represents different phase-to-phase conductors, and the calibrated different power parameters G i-k Compare with the preset range, where the endpoint values ​​of the preset range are preset values, and the specific values ​​are determined by the operator based on experience:

[0038] When G i-k ∈ preset range, no processing is performed;

[0039] when When the power parameter is within the preset range, the power parameter is calibrated as abnormal power, and the abnormal moment corresponding to the abnormal power is recorded. When the abnormal power appears continuously after the abnormal moment, the abnormal duration is recorded. If the abnormal duration is ≥5min, the specific abnormal period is recorded (that is, the total period lasting. After the abnormal power is confirmed, there will be a certain abnormal moment. After the abnormal power is generated, there will be a related duration, and the duration is the corresponding abnormal period). The phase conductor is calibrated as a fluctuating conductor, and the abnormal period is calibrated as the fluctuating period of the fluctuating conductor. The determined fluctuating conductor and the related fluctuating period are transmitted to the line calibration terminal;

[0040] Specifically, when related power fluctuations occur in related phase-to-phase conductors, corresponding abnormal power will be generated. After the abnormal power is generated, a related abnormal moment will be generated. The abnormal moment will have a corresponding duration, and the related fluctuation period can be locked.

[0041] The line calibration end, based on the determined fluctuating conductors and the related fluctuating periods, identifies whether the fluctuating periods between the fluctuating conductors are crossed, and based on the specific results of the identification, confirms and marks the interfering conductors, wherein the specific method of marking is:

[0042] Confirm the fluctuation time periods of the determined different fluctuation wires one by one, and identify whether there are intersecting time periods between the fluctuation time periods of the different fluctuation wires. If there are fluctuation time periods with intersecting time periods, such fluctuation time periods are marked as time periods to be processed and placed in a processing set. If there are no fluctuation time periods with intersecting time periods, no marking is performed. For example, there are three fluctuation wires A, B and C, of ​​which the fluctuation time period of A is 9:00-10:00 and 10:15-10:45, the fluctuation time period of B is 10:20-10:35, and the fluctuation time period of C is 9:15-9:45. Then the three fluctuation time periods of the three fluctuation wires: 9:00-10:00 and 9:15-9:45 are intersecting, so these two time periods are in one processing set. 10:15-10:45 and 10:20-10:35 are also intersecting time periods, so these two time periods are also placed in one processing set. There is no limit on the number of time periods in one processing set, and there can be multiple intersecting time periods.

[0043] Confirm the crossover periods of the waiting time periods in the processing set: randomly select a group of waiting time periods as the main time periods, and confirm the crossover periods between the main time periods and other waiting time periods. If there is a group of crossover periods with a total duration of more than 2 minutes among several groups of crossover periods, the fluctuation wire corresponding to this main time period will be marked as an interference wire. If it does not exceed 2 minutes, no relevant marking will be performed.

[0044] Then determine the main time period from other time periods to be processed in turn, confirm the intersecting time periods of the main time period and other time periods to be processed, and process them one by one, and confirm the interfering wires associated with this processing set one by one;

[0045] The confirmed interfering wires are displayed through the display terminal. Specifically, when there are multiple time periods to be processed in the processing set, a main time period A is randomly selected first, and a cross-time period analysis is performed to determine whether the wire corresponding to time period A is an interfering wire. Then other main time periods B are selected. At this time, time period A has been converted into a time period to be processed. The main time period B is analyzed in the same way to determine whether the wire corresponding to main time period B is an interfering wire. After processing and confirming one by one, the interfering wires in this processing set can be determined one by one.

[0046] The display end will display the confirmed interfering wires one by one for external relevant personnel to review and make relevant adjustments.

[0047] Example 2

[0048] In the specific implementation process of this embodiment, compared with the above-mentioned embodiment, this embodiment mainly focuses on the relevant adjustment process between the wires. When the wires are adjusted, the relevant power parameters are monitored in real time, so as to lock the best adjustment method and display it for the relevant operators to execute;

[0049] The specific execution end is the data processing end, which receives the relevant monitoring data in the wire adjustment process, and performs relevant analysis on the received relevant power parameters. The power parameter changes between each different wire are confirmed through the associated data analysis unit, and the approved value is locked. The determined approved value is transmitted to the adjustment method determination unit. The adjustment method determination unit selects the best adjustment method based on the determined groups of different approved values ​​and displays it. Since the corresponding interfering wire has been confirmed, it is necessary to adjust the distance of such interfering wire in the relevant adjustment process. The specific adjustment is performed autonomously by the relevant operator, and the performance of the power parameters of the corresponding wire in each adjustment process is recorded to determine the best adjustment method.

[0050] The specific method for the associated data analysis unit to lock its approved value is as follows:

[0051] The power parameters of different conductors monitored during the adjustment process are confirmed, and a power parameter change curve of the related conductors is generated. The change curve changes based on the timeline, so the horizontal coordinate axis of the change curve is the timeline, and the vertical coordinate axis is the power parameter;

[0052] From several power parameter change curves generated in real time, the line segments belonging to the preset range are marked as standard segments. From several power parameter change curves, the relevant standard segments that appear synchronously in the same period are confirmed, and such time periods are marked as optimal time periods. There may be multiple groups of optimal time periods or only one group, which depends on the specific data change curves. That is to say, the power trend line segments belonging to the standard range are the corresponding standard segments. Then, there are relevant standard segments in each curve. When all the standard segments appear at the same time, the time period associated with them at the same time belongs to the optimal time period.

[0053] Based on the confirmed optimal period, the standard section associated with this optimal period is analyzed. From each group of standard sections, the difference in power parameters between adjacent nodes is determined, and the difference = power parameter of the next node - power parameter of the previous node. From the determined several differences, the maximum value of the difference is selected as the standard value of this standard section. For example, each different moment in a standard section corresponds to a different power parameter, so there is a related difference in power parameters between each adjacent moment, that is, between adjacent nodes, and the difference between each node is different. Then, several differences will be generated in the same standard section, and the largest difference is the maximum fluctuation value generated by this standard section in this optimal period.

[0054] The standard values ​​of several standard sections corresponding to this optimal period are averaged to determine the approved value H q , where q represents different optimal time periods. Specifically, each different optimal time period corresponds to a different approved value H q Since there may be multiple confirmed optimal time periods, there will be multiple different approved values.

[0055] The adjustment mode determination unit is based on different rated values ​​H determined for each different optimal time period. q , from several approved values ​​H q A set of minimum values ​​is selected, the best time period corresponding to the minimum value is marked as the standard optimal time period, the adjustment record associated with the standard optimal time period is searched and displayed through the display terminal, and the external operator can make secondary adjustments based on the generated adjustment records to achieve the best interference shielding effect between several wires and achieve the best wire operation mode;

[0056] Specifically, during the actual analysis process, there is a related adjustment process in the relevant time period, so each different adjustment process will produce different power fluctuations. When the power fluctuation performance is at its best, that is, the corresponding standard time period, the related processing effect produced by this time period is the best, and in the actual analysis process, the corresponding adjustment record can be locked to achieve the best adjustment effect between the conductors.
