Description

Technical Field

[0001] This application relates to the field of power distribution network line analysis technology, and in particular to a method, apparatus, equipment and storage medium for correcting a line GIS model. Background Technology

[0002] A distribution network GIS (Geographic Information System) model is a topological data model centered on the topological connections between points, lines, and areas. This model can effectively reflect the distribution network's condition during data analysis and provide a comprehensive view of the network structure during joint analysis. However, compared to the main network, distribution networks are more complex, characterized by numerous devices and intricate wiring. Therefore, manually created distribution network GIS models often contain errors in the input of information such as device attributes.

[0003] Currently, the main method for correcting distribution network GIS models is to traverse each device and check its attribute information one by one. However, with numerous distribution network lines, this method is extremely inefficient. Furthermore, a single line may require multiple modifications, which easily leads to omissions, incorrect modifications, and erroneous changes. This results in the identification results of the distribution network GIS model not matching the actual situation, making it impossible to apply the model data in depth. Summary of the Invention

[0037] Figure 3 This is a schematic diagram of the structure of a computer device shown in an embodiment of this application. Detailed Implementation

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for correcting a route GIS model according to an embodiment of this application. The method for correcting a route GIS model according to this application can be applied to computer devices, including but not limited to smartphones, laptops, tablets, desktop computers, physical servers, and cloud servers. Figure 1 As shown, the method for correcting the GIS model of the line in this embodiment includes steps S101 to S104, which are detailed below:

[0040] Step S101: Obtain the ledger data of the line GIS model, the ledger data including line data and primary equipment data.

[0041] In this step, the line GIS model is a GIS model of the distribution network lines, the line data is the line data on the distribution network side, and the primary equipment data is the data of electrical equipment involved in power generation, transmission, and distribution in the distribution network lines, such as generators, transformers, circuit breakers, and switching equipment. It is understandable that in practical application scenarios, importing the line GIS model into the computer will also import the ledger data into the computer.

[0042] Step S102: Based on the ledger data, calculate the effective coverage rate of the line corresponding to the line GIS model and establish a GIS single-line map of the effectively covered line.

[0043] In this step, the effective line coverage rate is the coverage rate of effective lines in the line GIS model, representing the ratio of effective lines in the GIS model. When the effective line coverage rate is lower than the preset coverage rate, it indicates that there are abnormal equipment data in the GIS model, resulting in ineffective line coverage. Therefore, abnormal lines can be detected based on the effective line coverage rate. The GIS single-line map is a single-line map drawn based on the lines of primary equipment. It can represent the relationships between lines and between lines and equipment, thus enabling the location of abnormal equipment for abnormal lines based on the GIS single-line map.

[0044] In some embodiments, step S102 includes:

[0045] Based on preset effective coverage line conditions, the line data is filtered to obtain target line data that meets the preset effective coverage line conditions.

[0046] Using a preset effective coverage formula, the effective coverage rate of the line corresponding to the GIS model of the line is calculated based on the target line data.

[0047] Based on the target line data and the primary equipment data, a GIS single-line map of the effective coverage line is established.

[0048] In this embodiment, the line relationships and the relationships between the lines and the primary equipment are obtained based on the target line data and the primary equipment data. Based on these relationships, a GIS single-line map is created using GIS single-line map drawing software.

[0049] Optionally, the preset effective coverage line conditions include a first preset line condition and a second preset line condition. The filtering process of the target line data includes: filtering the line data based on the first preset line condition to obtain the number of medium-voltage public lines that meet the first preset line condition; and filtering the line data based on the second preset line condition to obtain the total number of medium-voltage public lines that meet the second preset line condition.

[0050] In this optional embodiment, exemplarily, the first preset line conditions are: ① The main line has at least one automated sectionalizing switch, and the number of medium-voltage users in each section is ≤30 and the number of low-voltage users is ≤2000; ② There is no public connection point or at least one public automated connection point, and its upstream section has an automated sectionalizing switch, forming a basic isolated power transfer network of "upstream section - downstream connection"; ③ When the number of medium-voltage users on the branch line is >10 or the number of low-voltage users is >1000, an automated sectionalizing circuit breaker needs to be installed at the beginning of the branch (an automated circuit breaker needs to be installed within 3 medium-voltage users after the branch point at the beginning of a large branch; if this condition is met, it is considered that an automatic circuit breaker has been installed). Further, the number of medium-voltage public distribution lines that meet the above three conditions is selected.

[0051] For example, the second preset line condition is as follows: for all medium-voltage public distribution lines already in operation, special lines such as those with short line radii (e.g., main line length not exceeding 2km), few power supply customers (e.g., medium-voltage customers ≤ 5 and low-voltage customers ≤ 2000), dedicated public lines (e.g., public medium-voltage customers = 0 and 1 < dedicated medium-voltage customers ≤ 15), single-customer lines (e.g., public medium-voltage customers = 0 and dedicated medium-voltage customers = 1), and unloaded lines (e.g., medium-voltage customers = 0 and number of connection points = 0) are excluded. Among these, lines with short radii and few power supply customers must meet the requirement of having no public connection points or at least one public automation connection point. Furthermore, the total number of medium-voltage public distribution lines that meet the above conditions is then counted from all medium-voltage public distribution lines already in operation.

[0052] Optionally, the preset effective coverage formula is:

[0053]

[0054] Wherein, G represents the line coverage efficiency, X represents the number of medium-voltage public lines that meet the first preset line conditions, and Y represents the total number of medium-voltage public lines that meet the second preset line conditions.

[0055] Step S103: Based on the effective coverage of the line and the GIS single-line map, locate the abnormal equipment data of the line GIS model.

[0056] In this step, abnormal lines are checked based on the effective coverage rate of the lines, and abnormal equipment is located based on the line GIS model. Specifically, analysis is conducted on issues such as missing or incorrectly filled data for public lines, dedicated lines, tie switches, tie switch connection attributes, large branch circuit breakers, and handcart switch IPs, as well as missing user numbers for dedicated transformers, to obtain the primary equipment data with abnormal data.

[0057] In some embodiments, step S103 includes:

[0058] Based on the effective coverage rate of the line, anomaly analysis is performed on multiple line objects in the line GIS model to identify target line objects that do not meet the preset effective coverage rate requirements, wherein each line object corresponds to a preset effective coverage rate requirement.

[0059] Based on the GIS single-line map, locate the target primary equipment data corresponding to the target line object, and the target primary equipment data is the abnormal equipment data.

[0060] In this embodiment, optionally, the line object includes at least one of the following: line trunk line, line circuit breaker, line public line, line dedicated line, dedicated transformer user number, and handcart switch.

[0061] For example:

[0062] (1) The main line is defined as the path from the outgoing switch to the power grid asset and is a tie switch with tie attributes. Based on the classification of ineffective line coverage, information on ineffective lines caused by incorrect identification of the main line due to the presence of improperly identified tie switches can be directly filtered out. Combined with the effective coverage-specific GIS single-line map, the location of the problematic tie switch can be directly located and the corresponding equipment ledger data can be displayed, thus identifying the ledger issues of the problematic tie switch. Then, a one-click correction function can be used to automatically correct the problematic ledger data to normal data, thereby resolving the ledger data issues that caused errors in the tie switch's tie attributes and asset attributes.

[0063] (2) If a line branch has more than 10 medium-voltage users or 1,000 low-voltage users, it is considered an important branch. Automatic circuit breakers need to be installed within the range of the first 3 medium-voltage users. The automatic circuit breakers must be power grid assets. Based on the classification of the results of the judgment that the line is not effectively covered, the relevant line information that is not effectively covered due to the failure to identify the automatic circuit breaker at the head of the large branch can be directly filtered out. Combined with the effective coverage special GIS single-line map, the location of the problematic automatic circuit breaker can be directly located and the equipment ledger data of the corresponding circuit breaker can be displayed. The ledger problem of the problematic automatic circuit breaker can be locked. Then, the ledger data of the problematic automatic circuit breaker can be automatically corrected to normal data through the correction function, thereby solving the problem ledger data that causes the asset attribute error of the automatic circuit breaker at the head of the large branch.

[0064] (3) The effective coverage judgment only judges public lines. When the line is a dedicated line, the effective coverage statistics result will default to no. According to the judgment result of the line not being effectively covered, the line information that is not judged for effective coverage because the line GIS ledger data attribute is dedicated line is filtered out. By accessing the line GIS ledger data, the problem of public or dedicated line errors can be locked. Then, the correction function can be used to correct it with one click, and the ledger asset data of the problem line will be automatically corrected to normal data, thereby solving the problem ledger data that caused the line public or dedicated line errors.

[0065] (4) When calculating the number of medium-voltage users on the line, public transformers are counted as 1 user, dedicated transformers with the same user number are counted as 1 user, and different user numbers are each counted as 1. Based on the classification of the judgment results of the line not being effectively covered, the relevant line information that is not effectively covered due to the duplicate calculation of dedicated transformers with the same user number in the GIS single-line map is filtered out. Combined with the dedicated transformer user markings in the dedicated GIS single-line map of effective coverage, the user number information of dedicated transformers with the same user number can be directly located. Then, the correction function can be used to correct the problem of the ledger data of the user number of the problematic dedicated transformers with the same user number with one click, thereby solving the problem of the ledger data that caused the error of duplicate calculation of dedicated transformers with the same user number.

[0066] (5) Automated switches are judged by the TYPE attribute of the switch. However, there is no corresponding automated TYPE relationship for handcart switches. Therefore, it is necessary to judge automatically by the IP address of the handcart switch. According to the judgment result of the line not being effectively covered, filter out the relevant line information that is not effectively covered because the main line passes through an automated handcart switch or the first end of a large branch is an automated handcart switch but is not identified. Combined with the handcart switch markings on the effective coverage special GIS single line map, lock the unidentified automated handcart switch problem log data, locate the IP address log data filled in by the handcart switch, and then use the correction function to make one-click correction to automatically correct the IP of the handcart switch of the problem line to normal data, thereby solving the problem log data of the handcart switch not being identified by automation due to the IP address.

[0067] Step S104: Correct the abnormal device data.

[0068] In this step, a preset correction function is used to correct the abnormal equipment data to normal equipment data based on the type of abnormality. This preset correction function can be a built-in feature of the GIS model building software, automatically correcting the data based on the type of abnormality in the primary equipment data to resolve issues of missing or incorrect data in the GIS model.

[0069] Further, after step S104, return to step S102 to continue locating abnormal equipment data and automatically correcting it until the effective coverage rate of the line is met.

[0070] It should be noted that (1) by calculating the effective coverage index, the ledger data and topology analysis of the main line / branch line, section switch / tie switch, number of medium voltage users / number of low voltage users, power grid assets / user assets, etc. of the line GIS model can be directly statistically analyzed. By analyzing the abnormal points of the effective coverage index and combining the statistically obtained ledger data, it is possible to quickly determine whether there are abnormalities in the GIS model data, and to quickly locate the problematic data of the GIS model and automatically correct it.

[0071] (2) The effective coverage index assesses various aspects of the GIS model, including main lines / branch lines, sectionalizing switches / tie switches, number of medium-voltage users / low-voltage users, and power grid assets / user assets, thereby identifying as many errors as possible in the GIS model. Therefore, each effective coverage index calculation can identify a large number of errors in the GIS model, greatly improving the efficiency of correction.
