Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission line repair, in particular to a power transmission line emergency repair method and system. BACKGROUND

[0002] With the increasing demand for electricity, the stable operation of the power transmission line is crucial, so it is necessary to monitor the power transmission line at all times to ensure that the power transmission line is repaired in time when a fault occurs, to ensure the normal operation of the power supply. By monitoring and analyzing the faults of each unit of the power transmission line, the corresponding repair personnel for each unit fault of the power transmission line are obtained, so as to realize efficient repair of the power transmission line, improve the repair efficiency, reduce the power outage time and reduce the power outage loss.

[0003] The prior art such as the invention patent application with publication number CN113594963A discloses a power transmission line emergency repair method and system. When the power transmission line tower collapses, the power transmission line tower collapse information is obtained, and the accident related line information is formed in combination with the power transmission line basic information. Based on the accident related line information and the pre-established tower system database, the information of the repair tower is configured. The repair tower is checked based on the information of the repair tower. The power transmission line emergency repair construction scheme is generated based on the information of the repair tower that passes the check and the accident related line information. The present application forms the initial configuration of the repair line environment by pre-establishing the tower system database and inputting the line information, configuring the repair tower and other steps, realizes the check of the repair tower and the generation of the repair construction scheme, and provides data support and strategy preparation for formulating the repair construction scheme.

[0004] For the above-mentioned scheme, the present application applicant finds that the above-mentioned technical problems at least have the following technical problems: the above-mentioned invention mainly generates the power transmission line emergency repair construction scheme based on the information of the repair tower that passes the check and the accident related line information after the power transmission line tower collapses, and does not monitor each unit of the power transmission line. Therefore, the corresponding fault risk of each unit of the power transmission line may occur, which may cause the interruption of the operation of the power transmission line or other abnormal operation. At the same time, the power transmission line detection is not comprehensive, which may cause the line to be unable to be repaired in time, the line fault to be aggravated, and the repair difficulty and the line loss to be increased. SUMMARY

[0005] In view of the above existing problems, when the main helium blower is diagnosed for failure, it often depends on artificial experience judgment and simple threshold comparison. This method is not only time-consuming but also has low accuracy, and cannot meet the needs of real-time monitoring and accurate diagnosis. The present application effectively makes up for this defect. The deep learning algorithm can automatically learn features from a large amount of data without human intervention, improving the efficiency and accuracy of fault diagnosis. By collecting the operation data of the main helium blower in real time, the deep learning model can identify the fault type in time and give a warning prompt, so that the maintenance personnel can take maintenance measures in time to ensure the stable operation of the main helium blower. At the same time, through the analysis of historical fault data, the deep learning algorithm can also optimize the operation and maintenance strategy of the main helium blower, improve the operation efficiency and service life of the main helium blower.

[0044] Embodiment 1

[0045] Reference Figure 1 For the first embodiment of the present application, the embodiment provides a power transmission line emergency repair method, comprising:

[0046] S1: Power transmission line monitoring: by monitoring each unit of the power transmission line in all time periods, obtaining the monitoring information of each unit of the power transmission line, and then determining whether each unit of the power transmission line has a fault, and screening the fault type of each unit of the power transmission line.

[0047] It should be noted that the monitoring information includes apparent parameters, electrical parameters, and insulation parameters, and the power transmission line is monitored by a camera and an electrical detection instrument in each unit in a full time period, so as to obtain the monitoring information of each unit of the power transmission line.

[0048] As an optional implementation, the judgment of whether each unit of the power transmission line has a fault is as follows: the apparent parameters of each unit of the power transmission line are compared with the initial apparent parameter threshold interval of the power transmission line stored in the database, and the electrical parameters and the insulation parameters of each unit of the power transmission line are compared with the initial electrical parameter threshold interval and the initial insulation parameter threshold interval of the power transmission line stored in the database. If the apparent parameters of a certain unit of the power transmission line are not within the initial apparent parameter threshold interval of the power transmission line stored in the database, or the electrical parameters and the insulation parameters of the unit of the power transmission line are not within the initial electrical parameter threshold interval and the initial insulation parameter threshold interval of the power transmission line stored in the database, it is determined that the unit of the power transmission line has a fault. In this way, whether each unit of the power transmission line has a fault is determined.

[0049] As an optional implementation, the type of the fault existing in each unit of the power transmission line is screened out, and the specific screening process is as follows: when each unit of the power transmission line has a fault, the abnormal information corresponding to each unit of the power transmission line is obtained. If the abnormal information corresponding to a certain unit of the power transmission line is apparent burning or dirt accumulation, it is determined that the type of the fault corresponding to the unit of the power transmission line is lightning strike fault or apparent fault. If the abnormal information corresponding to the unit of the power transmission line is current or voltage overload, it is determined that the type of the fault corresponding to the unit of the power transmission line is line overload or line short circuit. If the abnormal information corresponding to the unit of the power transmission line is leakage or low insulation resistance, it is determined that the type of the fault corresponding to the unit of the power transmission line is insulator aging or insulation fault. In this way, the type of the fault existing in each unit of the power transmission line is screened out.

[0050] S2: According to the type of the fault corresponding to each unit of the power transmission line, the fault information corresponding to each unit of the power transmission line is obtained, the fault difficulty coefficient corresponding to each unit of the power transmission line is analyzed, the operation information corresponding to each repair personnel is obtained, the operation coefficient corresponding to each repair personnel is analyzed, and the repair personnel corresponding to each unit of the power transmission line is screened out.

[0051] It should be noted that the fault information includes the line damage level and the line damage area, the line loss image corresponding to each unit of the power transmission line is captured by the camera, and is compared with each damage level interval corresponding to the power transmission line stored in the database. If the line loss image corresponding to a unit of the power transmission line is within a certain damage level interval corresponding to the power transmission line stored in the database, the level is taken as the line damage level of the unit. In this way, the line damage level corresponding to each unit of the power transmission line is obtained. The line damage area corresponding to each unit of the power transmission line is extracted from the line loss image corresponding to each unit of the power transmission line. The operation information includes operation fluency, familiarity and speed. The operation information of each repair personnel in each historical repair is obtained from the historical repair records of each unit of the power transmission line corresponding to each repair personnel in the database, including operation fluency, familiarity and speed. The average operation parameters are obtained by averaging the operation fluency, familiarity and speed corresponding to each historical operation, and are taken as the operation information corresponding to each repair personnel.

[0052] As an optional implementation, the analysis obtains the fault difficulty coefficient corresponding to each unit of the power transmission line, and the specific analysis process is as follows:

[0053] The calculation formula is as follows:

[0054]

[0056] It should be further noted that the weight factors of the line damage level and the line damage area are obtained by factor analysis method. First, the information of the line damage level and the line damage area is condensed, then the corresponding variance explanation rate is obtained, and finally the corresponding weight is obtained by dividing the variance explanation rate.

[0057] It should be further noted that information condensation refers to condensing multiple analysis items into several key summary indicators. The variance explanation rate refers to the contribution degree of each principal component or factor to the total variance, which is usually expressed by percentage, indicating how much the factor contains the original data information.

[0058] As an optional implementation, the analysis obtains the operation coefficients corresponding to each repair personnel, and the specific analysis process is as follows:

[0059] Through the calculation formula:

[0060]

[0061] The operation coefficients corresponding to the xth repair personnel are obtained through analysis, x is the number of each repair personnel, x = 1, 2,..., s, s is any integer greater than 2, λ' is a set reference repair speed, is a set reference repair proficiency, θ' is a set reference repair fluency, λ x is the repair speed corresponding to the xth repair personnel, is the repair proficiency corresponding to the xth repair personnel, θ x is the repair fluency corresponding to the xth repair personnel, v1, v2, and v3 are respectively a weight factor of the repair speed, a weight factor of the repair proficiency, and a weight factor of the repair fluency, 0 < v1 < 1, 0 < v2 < 1, and 0 < v3 < 1.

[0062] It needs to be explained again that the weight factor of the repair speed, the weight factor of the repair proficiency, and the weight factor of the repair fluency are obtained through the factor analysis method, the information of the repair speed, the repair proficiency, and the repair fluency is condensed first, then the corresponding variance explanation rate is obtained, and finally the corresponding weight is obtained by dividing the variance explanation rate.

[0063] As an optional implementation, the screening obtains the repair personnel corresponding to each unit of the power transmission line, and the specific screening process is as follows: the operation coefficients corresponding to each repair personnel are compared with a preset operation coefficient threshold value, if the operation coefficient corresponding to a repair personnel is greater than the preset operation coefficient threshold value, it is determined that the repair personnel has excellent ability, if the operation coefficient corresponding to a repair personnel is equal to the preset operation coefficient threshold value, it is determined that the repair personnel has medium ability, and if the operation coefficient corresponding to a repair personnel is less than the preset operation coefficient threshold value, it is determined that the repair personnel has qualified ability, the operation coefficients corresponding to each repair personnel are arranged in descending order according to the above comparison mode, so as to obtain each repair personnel, the fault difficulty coefficients corresponding to each unit of the power transmission line are arranged in descending order, so as to obtain the repair order corresponding to each unit of the power transmission line, and the repair order corresponding to each unit of the power transmission line is distributed according to the ranking corresponding to each repair personnel, so as to screen the repair personnel corresponding to each unit of the power transmission line.

[0066] As an optional implementation, the dangerous coefficient of the repair of each unit of the power transmission line is analyzed as follows:

[0067] Through the calculation formula:

[0068]

[0069] The dangerous coefficient ω of the repair of the mth unit of the power transmission line is analyzed m , m is the number of each unit, m = 1, 2,..., n, n is any integer greater than 2, gd' is the set reference height, kd' is the set reference passable width, gd m is the height corresponding to the mth unit of the power transmission line, kd m is the passable width corresponding to the mth unit of the power transmission line, ys m is the rainfall corresponding to the mth unit of the power transmission line, fl m is the wind force corresponding to the mth unit of the power transmission line, wd m is the terrain slope corresponding to the mth unit of the power transmission line, c1 and c2 are the weight factors of the height and the passable width respectively, 0 < c1 < 1, 0 < c2 < 1.

[0070] It should be further noted that the weight factors of the height and the passable width are obtained through the factor analysis method, the information of the height and the passable width is condensed first, then the corresponding variance explanation rate is obtained, and then the corresponding weight is obtained by dividing the variance explanation rate.

[0071] As an optional implementation, the safety carrying device of the repair personnel corresponding to each unit of the power transmission line is screened out, and the specific screening process is as follows: the danger coefficient of the repair corresponding to each unit of the power transmission line is compared with the danger coefficient threshold interval of each historical repair corresponding to each unit of the power transmission line stored in the database, if the danger coefficient of the repair corresponding to a certain unit of the power transmission line is within the danger coefficient threshold interval of a certain historical repair corresponding to the certain unit of the power transmission line stored in the database, the safety carrying device of the historical repair corresponding to the certain unit of the power transmission line stored in the database is taken as the safety carrying device of the repair personnel corresponding to the certain unit of the power transmission line, and the safety carrying device of the repair personnel corresponding to each unit of the power transmission line is screened out in this way.

A method for emergency repair of power transmission lines, characterized in that: include, By monitoring each unit of the transmission line around the clock, the monitoring information of each unit of the transmission line is obtained, thereby determining whether there is a fault in each unit of the transmission line and screening out the fault types in each unit of the transmission line. Based on the fault type corresponding to each unit of the transmission line, obtain the fault information corresponding to each unit of the transmission line, analyze and obtain the fault difficulty coefficient corresponding to each unit of the transmission line, and at the same time obtain the operation information corresponding to each emergency repair personnel, analyze and obtain the operation coefficient corresponding to each emergency repair personnel, and filter out the emergency repair personnel corresponding to each unit of the transmission line.

After the safety equipment carried by the emergency repair personnel corresponding to each unit of the transmission line is selected, the fault difficulty coefficient and emergency repair risk coefficient corresponding to each unit of the transmission line are compared with the comprehensive coefficient threshold corresponding to each historical emergency repair method of the transmission line stored in the database to select the reference emergency repair method for each unit of the transmission line. The system displays the reference repair methods for each unit of the transmission line and provides an early warning when a fault occurs in a certain unit of the transmission line.

The emergency repair method for transmission lines as described in claim 1, characterized in that: The specific process for determining whether each unit of the transmission line has a fault is as follows: The apparent parameters of each unit of the transmission line are compared with the initial apparent parameter threshold ranges of the corresponding transmission line stored in the database. At the same time, the electrical parameters and insulation parameters of each unit of the transmission line are also compared with the initial electrical parameter threshold ranges and initial insulation parameter threshold ranges of the corresponding transmission line stored in the database. If the apparent parameters of a certain unit of the transmission line are not within the initial apparent parameter threshold ranges of the corresponding transmission line stored in the database, or if the electrical parameters and insulation parameters of the corresponding unit of the transmission line are not within the initial electrical parameter threshold ranges and initial insulation parameter threshold ranges of the corresponding transmission line stored in the database, then it is determined that the unit of the transmission line has a fault. This is how the determination of whether each unit of the transmission line has a fault is made. The specific screening process for identifying fault types in each unit of the transmission line is as follows: When a fault occurs in any unit of the transmission line, the abnormal information corresponding to each unit is obtained. If the abnormal information corresponding to a certain unit of the transmission line is apparent burning or dirt accumulation, then the fault type corresponding to that unit of the transmission line is determined to be a lightning strike fault or an apparent fault.

The comprehensive coefficient of emergency repair for each unit of the transmission line is then compared with the comprehensive coefficient threshold of each historical emergency repair method of the transmission line stored in the database. If the comprehensive coefficient of emergency repair for a certain unit of the transmission line is the same as the comprehensive coefficient threshold of a certain historical emergency repair method of the transmission line stored in the database, then that historical emergency repair method is used as the reference emergency repair method for the emergency repair personnel of that unit of the transmission line.
