Description

Technical Field

[0001] The present invention belongs to the technical field of operation and maintenance management, and particularly relates to an operation and maintenance management method and system for a mobile ice melting switch-disconnector. Background Art

[0002] Existing technical solutions generally use ice melting switch-disconnectors to deal with the icing of transmission lines, thereby avoiding the occurrence of power accidents. At the same time, since icing conditions often occur in specific seasons and the usage frequency is relatively low, how to implement the operation and maintenance management of ice melting switch-disconnectors and ensure the reliability of their use has become an urgent technical problem to be solved.

[0003] Specifically, in the invention patent application CN202010837484.0, "A Remote Centralized State Evaluation System and Evaluation Method for an Ice Melting Device", the centralized monitoring center platform realizes the monitoring and operation and maintenance management functions of the ice melting substation, solving the problem that the existing technology cannot monitor the operation status of the DC ice melting device in real time at the remote main station. However, there are the following technical defects: During the operation and maintenance management of the ice melting switch-disconnector, since the ice melting switch-disconnector generally does not require ice melting treatment for most of the time, only the operation and maintenance monitoring and management of the ice melting switch-disconnector are carried out during the ice melting treatment. Once a problem occurs, due to the inability to control it in a timely and effective manner, the efficiency of ice melting treatment and the operation reliability of the transmission line are both difficult to meet the requirements.

[0004] In view of the above technical problems, specifically, the present application provides an operation and maintenance management method and system for a mobile ice melting switch-disconnector. Summary of the Invention

[0005] To achieve the object of the present invention, the present invention adopts the following technical solutions: In a first aspect, the present application provides an operation and maintenance management system for a mobile ice melting switch-disconnector, specifically including: An icing month determination module, a maintenance plan acquisition module, and an operation and maintenance processing module; Wherein the icing month determination module is responsible for determining the historical icing months of the transmission line; The maintenance plan acquisition module is responsible for obtaining the time intervals between different maintenance plan times of the transmission line and the historical icing months of the transmission line; The operation and maintenance processing module is responsible for determining the operation and maintenance processing strategy of the mobile ice melting switch-disconnector of the transmission line based on the time interval.

[0006] A further technical solution lies in that the historical icing months are the months in which the icing times of the transmission line are greater than a preset icing times.

[0007] A further technical solution lies in that the method for determining the operation and maintenance processing strategy of the mobile ice melting switch-disconnector of the transmission line is: Based on the time interval, determine the interval durations between different maintenance plan frequencies and the historical icing months; Take the maintenance plan frequencies with interval durations less than a preset interval duration as reference frequencies; According to the maintenance durations of the reference frequencies, determine the operation and maintenance treatment strategy for the mobile de-icing switch of the transmission line.

[0008] A further technical solution is that when the sum of the maintenance durations of different reference frequencies is greater than a preset maintenance duration threshold, it is determined that the mobile de-icing switch of the transmission line performs operation and maintenance treatment during the periods of different maintenance plan frequencies of the transmission line.

[0009] A further technical solution is that when the sum of the maintenance durations of different reference frequencies is not greater than a preset maintenance duration threshold, it is determined that the mobile de-icing switch of the transmission line performs operation and maintenance treatment using other transmission lines during the periods of different maintenance plan frequencies.

[0010] In a second aspect, the present application provides an operation and maintenance management method for a mobile de-icing switch, which is applied to the above-mentioned operation and maintenance management system for a mobile de-icing switch, and specifically includes: S1 Determine the historical icing data of different transmission lines in different reference weather intervals, and in combination with the historical date distribution data of the regions where the transmission lines are located in different reference weather intervals, determine the icing-risk transmission lines among the transmission lines; S2 Obtain the time intervals between different maintenance plan frequencies of the icing-risk transmission lines and the historical icing months of the icing-risk transmission lines. When it is determined based on the time interval that the mobile de-icing switch of the icing-risk transmission line needs to be moved, proceed to the next step; S3 Determine the matching transmission lines among the transmission lines according to the parameter similarity between different transmission lines and the icing-risk transmission lines; S4 Obtain the distribution data of the matching transmission lines in different regions, and in combination with the matching situation of the maintenance plans between different matching transmission lines, determine the mobile target region of the mobile de-icing switch in the region. When the matching transmission lines in the mobile target region are under maintenance, use the matching transmission lines to perform operation and maintenance treatment on the mobile de-icing switch.

[0011] The beneficial effects of the present invention are as follows: Based on the number of different maintenance plan times of the transmission line with icing risk and the time interval of the historical icing months of the transmission line with icing risk, it is determined whether the mobile de-icing switch of the transmission line with icing risk needs to be moved, realizing the judgment of whether the mobile de-icing switch needs to be moved from two perspectives: the maintenance data of the transmission line with icing risk and the operation and maintenance requirements of the mobile de-icing switch. This not only ensures the safety and stability of the operation of the mobile de-icing switch of the transmission line with icing risk with a high degree of matching during the maintenance period, but also avoids the technical problem that the reliability of the operation and maintenance management of the mobile de-icing switch of the transmission line with icing risk with a low degree of matching does not meet the requirements.

[0012] When the matching transmission line in the mobile target area is under maintenance, the operation and maintenance of the mobile de-icing switch are carried out using the matching transmission line, thus avoiding the technical problem that the timeliness of fault handling is difficult to meet the requirements caused by the original fault operation and maintenance management of the de-icing switch only during the ice melting process. It realizes the operation and maintenance during the corresponding period in the maintenance process, not only reducing the impact on the transmission line during the operation and maintenance, but also ensuring the reliability of the operation and maintenance of the de-icing switch and the stability of the work.

[0013] A further technical solution lies in that the historical icing data includes the historical icing times and the icing amount under different reference weather intervals.

[0014] A further technical solution lies in that the reference weather intervals are divided according to the preset weather data intervals where the monitored amounts of weather data in different dimensions are located.

[0015] A further technical solution lies in that the distribution data of the reference weather intervals includes the dates under different reference weather intervals and the distribution interval data between the dates.

[0016] A further technical solution lies in that the method for determining the transmission line with icing risk in the transmission line is as follows: Based on the historical icing data of the transmission line under different reference weather intervals, determine the historical icing times under different reference weather intervals; Take the reference weather intervals with historical icing times greater than the preset icing times threshold as the icing matching intervals; According to the date distribution data under different icing matching intervals, determine whether the transmission line is a transmission line with icing risk.

[0017] A further technical solution lies in that according to the date distribution data under different icing matching intervals, determining whether the transmission line is a transmission line with icing risk specifically includes: When the proportion of the sum of the number of dates in different icing matching intervals in different years is greater than the preset proportion of the number of dates, it is determined that the transmission line is an icing-risk transmission line.

[0018] A further technical solution is that the matching situation of the maintenance plans between the matching transmission lines is determined according to the overlapping periods of the number of maintenance plan times of different matching transmission lines.

[0019] A further technical solution is that the method for determining the moving target area of the mobile ice melting switch in the area is as follows: Based on the matching situation of the maintenance plans between different matching transmission lines, determine the number of maintenance plan times with overlapping periods between different matching transmission lines, and use whether there is an overlapping period to divide the number of maintenance plan times into overlapping times and non-overlapping times, and merge the planned maintenance times that belong to the overlapping times with each other into one overlapping maintenance time; Using the interval duration from the historical icing months, regard the matching transmission lines corresponding to the non-overlapping times with an interval duration less than the preset interval duration as available transmission lines, and regard the overlapping maintenance times and non-overlapping times with an interval duration less than the preset interval duration as available maintenance times; Determine whether the area is the moving target area of the mobile ice melting switch according to the number of available transmission lines and the available maintenance times.

[0020] A further technical solution is that determining whether the area is the moving target area of the mobile ice melting switch according to the number of available transmission lines and the available maintenance times specifically includes: Regard the area with the number of available transmission lines within the preset matching line number interval as the available area; Regard the available area with the largest available maintenance times as the moving target area of the mobile ice melting switch.

[0021] A further technical solution is that using the matching transmission lines for the operation and maintenance of the mobile ice melting switch specifically includes: Using the corresponding time period of the matching transmission lines in the number of maintenance plan times, turn on the mobile ice melting switch to observe the operating current of the mobile ice melting switch, and when the operating current is abnormal, output the operation and maintenance reminder data.

[0022] A further technical solution is that when the operating current is not within the preset operating current interval, it is determined that the operating current is abnormal.

When the matching transmission line in the moving target region is under maintenance, the mobile de-icing switch is maintained by using the matching transmission line.

[0035] Further, the historical icing data includes the historical icing times and the icing amount under different reference weather intervals.

[0036] Specifically, the reference weather intervals are divided according to the preset weather data intervals where the monitored amounts of weather data in different dimensions are located.

[0037] It should be noted that the distribution data of the reference weather intervals includes the dates under different reference weather intervals and the distribution interval data between the dates.

When the average value of the icing risk coefficients of different screened weather intervals is not within the preset risk coefficient interval, proceed to step S13.

[0044] Furthermore, determining that the mobile de-icing switch of the transmission line needs to be moved specifically includes: Based on the time interval, determine the interval duration between different maintenance plan times and the historical icing months; Use the maintenance plan times with interval durations less than the preset interval duration as reference times; According to the maintenance duration of the reference times, determine whether the mobile de-icing switch of the transmission line needs to be moved.

[0045] It should be noted that when the sum of the maintenance durations of different reference times is greater than the preset maintenance duration threshold, determine that the mobile de-icing switch of the icing risk transmission line does not need to be moved.

[0046] Furthermore, when the mobile de-icing switch of the icing risk transmission line does not need to be moved, use the corresponding time periods in different maintenance plan times of the icing risk transmission line to turn on the mobile de-icing switch for observing the operating current of the mobile de-icing switch.

[0049] Specifically, the parameters of the ice-risk transmission line include series resistance, series inductance, shunt capacitance, shunt conductance, and line length.

[0050] Specifically, the method for determining the matching transmission line is as follows: Based on the deviation of the parameters of the transmission line in different dimensions from those of the ice-risk transmission line, determine the parameter deviation amounts in different dimensions; Take the transmission lines with parameter deviation amounts in different dimensions all within the preset parameter deviation amount range as the matching transmission lines.

[0051] It should be noted that the matching situation of the maintenance plans between the matching transmission lines is determined according to the overlapping periods of the maintenance plan times of different matching transmission lines.

[0052] Furthermore, the method for determining the moving target area of the mobile de-icing switch in the area is as follows: Based on the matching situation of the maintenance plans between different matching transmission lines, determine the number of maintenance plans with overlapping periods between different matching transmission lines, and use whether there is an overlapping period to divide the number of maintenance plans into overlapping times and non-overlapping times, and merge the planned maintenance times that belong to the overlapping times with each other into one overlapping maintenance time; Using the interval duration from the historical icing months, take the matching transmission lines corresponding to the non-overlapping times with an interval duration less than the preset interval duration as the available transmission lines, and take the overlapping maintenance times and non-overlapping times with an interval duration less than the preset interval duration as the available maintenance times; Determine whether the area is the moving target area of the mobile de-icing switch according to the number of available transmission lines and the available maintenance times.

[0053] It can be understood that determining whether the area is the moving target area of the mobile de-icing switch according to the number of available transmission lines and the available maintenance times specifically includes: Take the area with the number of available transmission lines within the preset matching line number range as the available area; Take the available area with the largest available maintenance times as the moving target area of the mobile de-icing switch.

[0055] Optionally, the method for determining the moving target area of the mobile de-icing switch in the area is as follows: Obtain the quantity of matching transmission lines in the area. When the quantity of matching transmission lines in the area is less than the preset value of the quantity of matching lines, it is determined that the area does not belong to the moving target area of the mobile de-icing switch; When the quantity of matching transmission lines in the area is not less than the preset value of the quantity of matching lines: Based on the matching situation of maintenance plans between different matching transmission lines, determine the number of maintenance plans with overlapping time periods between different matching transmission lines, and divide the number of maintenance plans into overlapping times and non-overlapping times using whether there are overlapping time periods. Combine the planned maintenance times that belong to the overlapping times with each other into one overlapping maintenance time. When the sum of the non-overlapping times and the overlapping maintenance time in the area does not meet the requirements, it is determined that the area does not belong to the moving target area of the mobile de-icing switch; When the sum of the non-overlapping times and the overlapping maintenance time in the area meets the requirements: When the overlapping maintenance time is within the preset overlapping maintenance time interval: Obtain the quantity of matching transmission lines with non-overlapping times.

Take the matching transmission lines corresponding to the non-overlapping times with an interval duration less than the preset interval duration as the matching transmission lines, and take the overlapping maintenance times and non-overlapping times with an interval duration less than the preset interval duration as the available maintenance times. When either the quantity of available transmission lines or the available maintenance times do not meet the requirements, it is determined that the area does not belong to the moving target area of the mobile de-icing switch; When both the quantity of available transmission lines and the available maintenance times meet the requirements: Determine the quantity matching coefficient of the area with the preset quantity matching coefficient corresponding to the quantity of available transmission lines. Multiply the available maintenance times by the quantity matching coefficient to obtain a maintenance matching value, and take the area with the largest maintenance matching value as the moving target area of the mobile de-icing switch.

[0056] Further, the operation and maintenance of the mobile de-icing switch is performed by using the matched transmission line, which specifically includes: During the corresponding time period of the maintenance plan times of the matched transmission line, the mobile de-icing switch is turned on to observe the operating current of the mobile de-icing switch, and when the operating current is abnormal, output reminder data for operation and maintenance.

[0057] Specifically, when the operating current is not within the preset operating current range, it is determined that the operating current is abnormal.
