Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution lines, and in particular to a power distribution line defect penetration treatment method, system, device and medium. BACKGROUND

[0002] With the rapid development of China's economy and the acceleration of urbanization process, the demand for electricity continues to grow. As the "last mile" of power supply, the reliability and stability of power distribution lines are crucial. 10kV power distribution lines are widely distributed in cities and rural areas, directly related to the power quality of the general public. Under the wave of digital transformation, information technology is constantly integrated into the power sector, bringing new opportunities for the operation and maintenance management of power distribution lines. Through real-time monitoring and intelligent analysis of power distribution lines using big data, artificial intelligence and other technical means, defects in the lines can be detected and handled in a timely manner to ensure the safety and stability of power supply, which has become an important direction for the development of the power industry.

[0003] However, there are still many problems in the current operation and maintenance management of 10kV power distribution lines. On the one hand, the traditional operation and maintenance method mainly relies on manual inspection, which is inefficient and has great limitations. Manual inspection cannot achieve comprehensive and real-time monitoring of the lines, and some defects with strong concealment may be missed, leading to defects that cannot be discovered and handled in a timely manner, increasing the risk of line failure. On the other hand, when determining the treatment area and developing the treatment plan, there is a lack of scientific and reasonable methods, and it is mainly based on the experience of operation and maintenance personnel, which is highly subjective. This makes the determination of the power outage range not accurate enough, often resulting in a large power outage range, which not only wastes electricity but also has a great impact on normal power consumption of users. In addition, the existing operation and maintenance management lacks effective quantitative evaluation of the treatment effect, making it difficult to accurately judge the actual contribution of a certain treatment measure to improving the reliability of the lines, which is not conducive to optimizing subsequent operation and maintenance strategies and resource allocation. SUMMARY

[0004] In view of the above existing problems, the present application is proposed.

[0005] Therefore, the present application provides a power distribution line defect penetration treatment method to solve the problems of inaccurate defect positioning, strong subjectivity in selecting treatment areas, inability to quantify treatment effects, and unreasonable resource allocation in power distribution line operation and maintenance.

[0006] To solve the above technical problems, the present application provides the following technical solution: a power distribution line defect penetration treatment method, comprising the following steps:

[0007] Obtaining power distribution line operation data;

[0008] Based on the power distribution line operation data, the power distribution line is divided into multiple power outage sections;

[0009] calculate a rectification ratio of the power outage section, and determine whether the power distribution line needs to be rectified according to the rectification ratio;

[0010] If the power distribution line needs to be rectified, a rectification priority of the power outage area is calculated, and the power distribution line is rectified according to the rectification priority.

[0011] As a preferred scheme of the power distribution line defect penetration rectification method, the power distribution line is divided into multiple levels of power outage sections based on the operation data of the power distribution line, including:

[0012] According to the switch configuration of the power distribution line, system logic division is performed from the start end to the end of the feeder to form multiple levels of power outage sections, wherein each level of power outage section is nested with each other.

[0013] The beneficial effect of the preferred technical scheme is that the division method changes the previous fuzzy defect positioning condition, so that the operation and maintenance personnel can clearly know the condition of each section, and the hierarchical nested structure helps to flexibly select a suitable level of power outage section for rectification according to the severity and influence range of the defect, thereby avoiding blind expansion of the power outage range.

[0016] The rectification ratio is calculated and obtained based on the fault power outage probability and the planned power outage influence.

[0017] The beneficial effect of the preferred technical scheme is that, compared with the traditional experience-dependent judgment method, the data model-based calculation method obtains the fault power outage probability and the planned power outage influence more objectively and accurately. By comprehensively considering the fault power outage probability and the planned power outage influence, the line operation state and potential risks can be comprehensively evaluated, so that the operation and maintenance decision is no longer blind, the accuracy of the judgment can be improved, and the operation and maintenance resources can be reasonably arranged to preferentially process the line sections with higher risks.

[0018] As a preferred scheme of the power distribution line defect penetration rectification method, whether the power distribution line needs to be rectified is determined according to the rectification ratio, including:

[0019] The rectification ratio is compared with a preset threshold value, if the rectification ratio is greater than the preset threshold value, it is determined that the power distribution line needs to be rectified, a rectification priority of the power outage area is calculated, and the power distribution line is rectified according to the rectification priority.

[0020] If the governance ratio is less than the preset threshold value, it is determined that the current power distribution line does not need to be governed, and the power distribution line operation data is continuously monitored to periodically recalculate the governance ratio.

[0021] As a preferred scheme of the power distribution line defect penetration governance method, if the power distribution line needs to be governed, the governance priority of the power outage area is calculated, and the power distribution line is governed according to the governance priority, including:

[0022] Based on the power distribution line operation data, the defect concentration of the power outage section is calculated, and the defect concentration area is obtained according to the defect concentration.

[0023] In the defect concentration area, the governance priority of the power outage section is weighted calculated, and the governance report is generated according to the governance priority.

[0024] The beneficial effects of the preferred technical scheme are that the defect concentration area is determined, the operation and maintenance personnel can quickly focus on the core problem, and resources are not wasted in areas with no defects or fewer defects. By weighted calculating the governance priority, key factors such as the number of defects, the number of users involved, and the number of historical annual trips are considered, the importance and urgency of different power outage sections can be scientifically sorted, unnecessary operation and maintenance costs are reduced, the overall operation and maintenance efficiency of the power distribution line is improved, and the influence of line failure on user power consumption is minimized.

[0025] As a preferred scheme of the power distribution line defect penetration governance method, the calculation formula of the governance priority is:

[0026] P i =α·D i +β·U i +γ·R i

[0027] Wherein, D i is the number of defects in the power outage section i, U i is the number of users involved in the power outage section i, R i is the number of historical annual trips of the power outage section i, α, β, γ are weight coefficients, and P i The higher the governance priority is.

[0028] As a preferred scheme of the power distribution line defect penetration governance method, the calculation formula of the fault power outage probability and the planned power outage influence is:

[0029]

[0030] Wherein, P f is the fault power outage probability, and P pN is the number of households affected by planned power outage i T is the number of households affected by power outage caused by the i-th type of fault i T is the average power outage time of the i-th type of fault y M is the total power supply time of a year j L is the number of users designed for the j-th planned power outage j T is the duration of the j-th maintenance.

[0031] Another object of the present application is to provide a system for improving short-time high-frequency energy storage efficiency.

[0032] To solve the above technical problems, the present application provides the following technical solutions: a system for improving short-time high-frequency energy storage efficiency, comprising: a data acquisition module for acquiring power distribution line operation data;

[0033] A section division module is used to divide the power distribution line into multiple power outage sections based on the power distribution line operation data.

[0043] In order to make the above objectives, features and advantages of the present application more apparent and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0048] S106: If the power distribution line needs to be treated, calculate the treatment priority of the power outage area, and treat the power distribution line according to the treatment priority.

[0049] It should be noted that the system of the present application systematically solves the problems of fuzzy defect positioning, subjective decision-making and low efficiency of resource allocation in traditional power distribution line operation and maintenance. The present application realizes accurate positioning of defects by obtaining power distribution line operation data and performing multi-level power outage section division, provides a clear target for subsequent treatment; calculates the treatment ratio and compares it with the threshold value, which can scientifically judge whether the line needs to be treated based on quantitative analysis, avoiding the blindness of experience decision-making; after determining that the line needs to be treated, the treatment priority is calculated and the treatment is carried out accordingly, considering factors such as defect quantity, user influence and historical failure, ensuring that resources are tilted to high-risk areas. The present application not only improves the pertinence and efficiency of defect treatment, reduces unnecessary power outage range and time, but also optimizes the allocation of operation and maintenance resources, improves the reliability and stability of the power distribution line, and ultimately reduces the operation and maintenance cost and improves the user's power experience.

[0050] Embodiment 2, refer to Figures 1-3 For an embodiment of the present application, based on the above embodiment, a power distribution line defect penetration treatment method is provided.

[0051] In the embodiment of the present application, in step S100, the 10kV power distribution line operation data is obtained by using the acquisition device, specifically, the 10kV power distribution line operation data includes defect position, defect type, discovery time, switch opening and closing state, switch position, power outage section involved household number, power outage section historical annual trip number, power outage time caused by each type of fault, average power outage time of each type of fault and line length and other data; after obtaining the power distribution line operation data, the power distribution line operation data is preprocessed.

[0052] In an optional embodiment, the power distribution line operation data can be collected and obtained by using intelligent inspection unmanned aerial vehicles, online monitoring sensor arrays, fault recording devices and other equipment. The intelligent inspection unmanned aerial vehicle is equipped with high-definition camera and infrared detection module, which can quickly locate the defect position and identify the type; the online monitoring sensor array collects data such as switch opening and closing state, line current and voltage in real time; the fault recording device accurately records information such as power outage time household number and trip number when the fault occurs. After obtaining the power distribution line operation data, the power distribution line operation data is preprocessed.

[0053] In an optional embodiment, the preprocessing can include data cleaning, format conversion, outlier repair, etc. Specifically, the data cleaning removes duplicate records by setting logical rules, such as deleting redundant reported data of the same defect based on double comparison of defect position coordinates and timestamps; the format conversion uniformly converts heterogeneous data collected by different devices into a standard structured format, facilitating subsequent model calculation; the outlier repair intelligently fills in missing key data such as outage household number and line length by using a machine learning algorithm in combination with historical data and associated section data, ensuring that the data input into the model is complete and accurate.

[0054] It should be noted that the present application comprehensively collects multi-dimensional data such as defect position, switch state, and user influence, completely covers key information of line operation, ensures that accurate data support can be obtained for subsequent multi-level outage section division, treatment ratio calculation, priority evaluation, and other links, avoids defect positioning deviation and treatment decision errors caused by data loss; at the same time, the collected data is preprocessed to effectively eliminate data noise and errors, improve data quality and usability, make the data input into the fault outage probability analysis model and priority calculation model more accurate and reliable, and thus ensure the scientificity of the model output results, improve the treatment efficiency and resource utilization efficiency, and enhance the line operation stability and power supply reliability.

[0055] In the embodiment of the present application, the division logic of dividing the distribution line into multi-level outage sections based on the distribution line operation data in step S102 is as follows:

[0056] According to the switch configuration of the distribution line, the system logic is divided from the start end to the end of the feeder, forming multi-level outage sections, wherein each level of outage section is nested in each other.

[0057] In the embodiment of the present application, the 10kV distribution line is divided as follows:

[0058] The first-level outage section: the full-line outage range from the outlet of the transformer substation to the farthest end;

[0059] The second-level outage section: a certain middle section interval containing multiple faults within the first-level range;

[0060] The third-level and fourth-level outage sections: smaller ranges within a certain second-level section;

[0061] It should be noted that the section division is penetrative nesting, such as "third-level containing fourth-level, second-level containing third-level", and the division result is as shown in Figure 2 and Figure 3 When the operation and maintenance personnel plan to treat defects, a penetrative section can be selected according to the defect distribution density and concentration, so that the outage range is as small as possible, but can cover the most defects, improving the treatment efficiency.

[0062] In an alternative embodiment, step S102 of dividing the power outage section can adopt a topology analysis method, which defines the line section between adjacent switches as a basic unit based on the topology model of the distribution line. Starting from the feeder head, the section is divided step by step downstream from the substation outlet switch according to the opening and closing state and connection relationship of the switch. For the case of branch line, the section is divided to the end of each branch line with the branch switch as the node. In the division process, the first-level power outage section (full line range) is determined first according to the order from large to small, and then the area containing multiple fault points is selected as the second-level power outage section in the first-level section according to the defect distribution, and the process is repeated.

[0063] In another alternative embodiment, step S102 of dividing the power outage section can also adopt a load clustering division method, which combines the outage section involved household number, real-time load data and other information in the operation data of the distribution line to perform load clustering analysis on the line. The areas with similar load characteristics and concentrated user distribution are divided into the same power outage section.

[0064] For example, the nodes on the distribution line are clustered using a clustering algorithm, and the load size and number of users of the nodes are used as clustering features. After clustering, the clustering results and switch positions are used to determine the power outage sections at different levels.

[0065] In the embodiment of the application, step S104 of calculating the treatment ratio of the power outage section includes sub-steps A1-A3 according to the treatment ratio to determine whether the distribution line needs to be treated.

[0066] A1: inputting the operation data of the distribution line into a fault outage probability analysis model to obtain the fault outage probability and planned outage influence of the distribution line through the fault outage probability analysis model;

[0067] A2: calculating and obtaining the treatment ratio based on the fault outage probability and the planned outage influence;

[0068] A3: comparing the treatment ratio with a preset threshold value, if the treatment ratio is greater than the preset threshold value, it is determined that the distribution line needs to be treated, the treatment priority of the power outage area is calculated, and the distribution line is treated according to the treatment priority; if the treatment ratio is less than the preset threshold value, it is determined that the current distribution line does not need to be treated, the operation data of the distribution line is continuously monitored, and the treatment ratio is recalculated regularly.

[0069] In the embodiment of the application, the calculation formula of the fault outage probability and the planned outage influence is:

[0070]

[0071] wherein, P f is the fault outage probability, Pp N is the number of households affected by the planned outage i T is the number of households affected by the outage caused by the i-th fault i T is the average outage time of the i-th fault y M is the total power supply time of a year j L is the number of users designed for the j-th planned outage j is the duration of the j-th maintenance.

[0072] In an embodiment of the present application, the remediation ratio calculation formula is:

[0073] ΔS = ∑(P i × T i × N i )

[0074] wherein ΔS is the remediation ratio, P i is the annual fault probability caused by the i-th defect, T i is the average fault recovery time per hour, N i is the number of users in the section where the defect is located.

[0075] In an embodiment of the present application, the calculation formula of the preset threshold is:

[0076] S y = t × N y

[0077] wherein S y is the preset threshold, N y is the number of households affected by the remediation outage, and t is the planned outage time.

[0078] If ΔS > S y , it is considered that the remediation cost performance is high, it is determined that the distribution line needs to be managed, the remediation priority of the outage area is calculated, and the distribution line is managed according to the remediation priority.

[0079] In an alternative embodiment, the risk matrix evaluation method can be used to determine whether the line needs to be managed, the fault outage probability and the planned outage impact are divided into three risk levels of high, medium and low respectively, and a two-dimensional risk matrix is constructed. The calculated fault outage probability and planned outage impact are corresponded to the corresponding position of the matrix, if the result falls in the high-risk area, that is, the fault outage probability is high and the planned outage impact is high, it is directly determined that the distribution line needs to be managed; if it is in the medium-risk area, the historical data and the importance of regional power consumption are comprehensively evaluated, for example, there are hospitals, data centers and other important users in the area, it is determined that it needs to be managed; if it is in the low-risk area, the present situation is maintained and continues to be monitored.

[0080] In another alternative embodiment, a multi-objective decision analysis method can also be used to judge whether the line needs to be managed, and multiple factors such as the improvement ratio, user satisfaction influence, and management cost are taken as decision targets, and corresponding weights are set for each target, the improvement ratio weight is 0.4, the user satisfaction influence weight is 0.3, and the management cost weight is 0.3. Through the fuzzy comprehensive evaluation method, each target is quantitatively scored, and then the comprehensive score is calculated according to the weight. A comprehensive score threshold is set, if the calculated comprehensive score is higher than the threshold, it is determined that the distribution line needs to be managed, otherwise, it continues to be monitored.

[0081] It should be noted that the calculation of the fault outage probability and the planned outage influence integrates key information such as historical faults and user influence, and converts the line operation risk into a quantitative index, which is more objective and accurate than traditional experience judgment. The improvement ratio is calculated according to the fault outage probability and the planned outage influence, and compared with the preset threshold to build a standardized management decision mechanism. If the improvement ratio is greater than the preset threshold, it is determined that management is needed, this way can accurately identify the lines with high risk and high value management needs, avoid blind improvement work, and prevent resource waste; if the improvement ratio is less than the preset threshold, it continues to be monitored, ensures that resources are concentrated on lines that really need to be managed, and realizes efficient allocation of operation and maintenance resources. The present application provides clear and definite decision basis for operation and maintenance personnel through quantitative comparison, reduces subjective judgment deviation, can improve the scientificity and intelligent level of distribution line operation and maintenance management, and reduces operation and maintenance cost.

[0082] In the embodiment of the present application, if the distribution line needs to be managed in step S106, the improvement priority of the outage section is calculated, and the distribution line is managed according to the improvement priority, which further includes sub-steps B1-B3:

[0083] B1: Based on the operation data of the distribution line, the defect concentration degree of the outage section is calculated, and the defect concentration area is obtained according to the defect concentration degree.

[0084] B2: The improvement priority of the outage section is calculated in the defect concentration area, and the improvement report is generated according to the improvement priority.

[0085] In the embodiment of the present application, the calculation formula of the defect concentration degree of the outage section is:

[0086]

[0087] Wherein, D k is the defect density of the kth outage section, n k is the number of defects in the outage section, and L k is the length of the outage section or the number of equipment nodes.

[0088] In the embodiment of the present application, the calculation formula of the improvement priority is:

[0089] P i = a · D i + b · U i + g · R i

[0090] wherein, D i is the number of defects in the outage section i, U i is the number of users involved in the outage section i, R i is the number of historical annual trips of the outage section i, a, b, g are weight coefficients, P i The higher the priority of the rectification is, the higher the rectification priority is.

[0091] In the embodiment of the present application, all sections are sorted according to D k , and the top several most dense outage sections are selected as the defect concentration area.

[0092] In the embodiment of the present application, the rectification report includes the recommended rectification section number, the suggested switch position to be disconnected, the predicted annual outage time per household to be reduced, and the corresponding rectification cost performance. The defect account and the outage record are updated according to the rectification report, which is used for dynamic strategy optimization in the next cycle.

[0093] It should be noted that the present application can quickly locate the core area with high incidence of problems in the line, avoid scattered resource investment; the rectification priority is calculated by weighting, which comprehensively considers the number of defects, user influence and historical fault conditions, so that the determination of the rectification order is more in line with the actual demand, and the sections with the greatest impact on power supply reliability and user experience are processed in priority. The generated rectification report not only clearly defines the specific management object and operation scheme, but also quantifies the rectification benefit, providing clear guidance for operation and maintenance decision-making. According to the report, the defect account and the outage record are updated, realizing dynamic management of operation and maintenance data, providing strong support for optimization and iteration of subsequent operation and maintenance strategies, reducing line fault risk and optimizing resource allocation.

[0094] Example 3, referring to Tables 1-2, is an embodiment of the present application, which provides a distribution line defect penetration management method based on the above-mentioned embodiment. In order to verify the beneficial effects of the present application, scientific demonstration is carried out through experiments.

[0095] Taking a certain 10kV distribution line as an example, its structure is as follows:

[0096] The total length is 35km, and there are 14 switch sections in total.

[0097] Inspection found 26 defect points, as shown in Table 1.

[0098] Table 1: Defects of distribution line

[0099] Section number Starting node Defect number S1-S2 Main transformer breaker-switch A 1 S2-S3 Switch A-switch B 0 S3-S4 Switch B-switch C 6 S4-S5 Switch C-branch D 5 S5-S6 Branch D-end 2 Other sections Several Little or none

[0100] According to the analysis in Table 1, there are 11 defects in the S3-S5 section, with the highest density. It is recommended to construct a secondary power outage section in the S3-S5 section for remediation, disconnect the switches at S3 and S5, and perform penetrating remediation using the method of the present invention.

[0101] Typical data before and after treatment are shown in Table 2;

[0102] Table 2 Governance data

[0103]

[0104] According to Table 2, the comprehensive power outage probabilities after rectification are calculated as follows:

[0105]

[0106] The results show that the comprehensive power outage impact of the method of the present invention was reduced by about 33.3%, and compared with conventional remediation (disconnecting the entire S1 section, covering all 14 sections), the power outage range of the present invention was compressed from 35km to about 10km; the number of users affected by the power outage decreased by nearly 60%; but it was still able to cover about 42% of the defects (11 / 26); effectively balancing operation and maintenance resources and the impact on user electricity consumption.
