Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a method for correcting a GIS model of a route provided by an embodiment of the present application. The method for correcting the GIS model of the route in the embodiment of the present application can be applied to computer equipment, which includes but not limited to smart phones, notebook computers, tablet computers, desktop computers, physical servers, cloud servers and other equipment. As shown in Figure 1, the correction method of the route GIS model of the present embodiment includes step S101 to step S104, detailed description is as follows:

In step S101, the ledger data of the route GIS model is acquired, and the ledger data includes route data and primary equipment data.

In this step, the line GIS model is the GIS model of the distribution network line, the line data is the line data on the side of the distribution network, and the primary equipment data is the data of the electrical equipment involved in the production, transmission and distribution of electric energy in the distribution network line. Equipment such as generators, transformers, circuit breakers and switchgear etc. It can be understood that, in an actual application scenario, when the route GIS model is imported into the computer equipment, the ledger data will also be imported into the computer equipment.

Step S102, based on the ledger data, calculate the effective coverage rate of the line corresponding to the GIS model of the line and establish a GIS one-line diagram of the effective coverage line.

In this step, the effective line coverage rate is the coverage rate of effective lines in the line GIS model, which can represent the ratio of effective lines in the GIS model. When the coverage rate of the effective line is lower than the preset coverage rate, it means that the GIS model has abnormal equipment data and the line cannot be effectively covered, so that the abnormal line can be detected according to the effective coverage rate of the line. The GIS one-line diagram is a one-line diagram based on the line drawing of primary equipment, which can represent the relationship between lines and lines, lines and equipment, so that abnormal equipment can be located for abnormal lines according to the GIS one-line diagram.

In some embodiments, the step S102 includes:

Screening the line data based on preset effective coverage line conditions to obtain target line data satisfying the preset effective coverage line conditions;

Using the preset effective coverage rate formula to calculate the effective coverage rate of the line corresponding to the GIS model of the line according to the target line data;

Based on the target line data combined with the primary equipment data, a GIS single-line diagram of the effectively covered line is established.

In this embodiment, the line relationship and the relationship between the line and the primary equipment are obtained according to the target line data and the primary equipment data. According to these relationships, the GIS one-line diagram drawing software is used to establish the GIS one-line diagram.

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

In this optional embodiment, for example, the first preset line condition is: ① There is at least one automatic section switch on the main line of the line, and the number of medium-voltage users in each section is ≤ 30 households, and the number of low-voltage users ≤2000 households; ②There is no public contact point or at least one public automatic contact point, and there is an automatic segment switch in the front section to form a "front segment-rear contact" that can be isolated and transferred to the basic network frame; ③The branch line of the line When the number of medium-voltage users > 10 or the number of low-voltage users > 1000, an automatic demarcation circuit breaker needs to be installed at the head end of the branch (an automatic circuit breaker needs to be installed within the range of 3 medium-voltage users after the branch point at the head end of the large branch, if it meets is in line with the installed). Further, the number of medium-voltage public distribution lines that meet the above three conditions is screened out.

Exemplarily, the second preset line condition is: for all medium-voltage public distribution lines that have been put into operation, exclude lines with a relatively short radius (such as lines with a trunk line length not exceeding 2 km), and a small number of power supply households (such as medium Number of high-voltage users ≤ 5 and low-voltage users ≤ 2000), public line dedicated (such as the number of public medium-voltage users = 0 and 1 < the number of dedicated medium-voltage users ≤ 15), single users (such as the number of public medium-voltage users = 0 and Dedicated medium-voltage subscribers = 1) and unloaded lines (such as medium-voltage subscribers = 0, number of contact points = 0) and other special lines. Among them, the radius of the line is relatively short and the number of power supply households is small. There must be no public contact point or at least one public automation contact point. Further, the total number of medium-voltage public distribution lines meeting the above conditions is counted out of all medium-voltage public distribution lines that have been put into operation.

Optionally, the preset effective coverage ratio formula is:

Wherein, G is the efficiency of line coverage, X is the number of medium-voltage public lines meeting the first preset line condition, and Y is the total number of medium-voltage public lines meeting the second preset line condition.

Step S103, based on the effective coverage of the line and the GIS one-line diagram, locate the abnormal equipment data of the GIS model of the line.

In this step, check the abnormal line according to the effective coverage of the line, and locate the abnormal equipment according to the GIS model of the line. Specifically, the data omission and wrong filling of the public line, dedicated line, contact switch, contact attribute of the contact switch, large branch circuit breaker, handcart switch IP, etc., and the lack of special variable user number are analyzed, and the primary equipment with abnormal data is obtained. data.

In some embodiments, the step S103 includes:

Based on the effective coverage rate of the line, abnormal analysis is performed on multiple line objects of the GIS model of the line, and target line objects that do not meet the requirements of the effective coverage rate of the preset line are determined, wherein each of the line objects corresponds to a preset Line effective coverage requirements;

Based on the GIS one-line diagram, locate target primary equipment data corresponding to the target line object, where the target primary equipment data is the abnormal equipment data.

In this embodiment, optionally, the line object includes at least one of a main line, a circuit breaker, a public line, a private line, a dedicated subscriber number, and a handcart switch.

Exemplarily:

(1) The main line of the line is the connection switch path from the outlet switch to the grid asset and is the connection attribute. The relevant line information that is not effectively covered due to the incorrect identification of the main line, combined with the special GIS one-line diagram for effective coverage, can directly locate the position of the problem contact switch and display the equipment account data of the corresponding switch, and lock the account problem existing in the problem contact switch . Then use the correction function to perform one-click correction, and automatically correct the problem ledger data to normal data, thereby solving the problem ledger data that causes errors in the contact attributes and asset attributes of the contact switch.

(2) If there are more than 10 medium-voltage users or 1,000 low-voltage users in the line branch, an important branch will be formed. It is necessary to install automatic circuit breakers within the scope of the three medium-voltage users at the head end, and the automatic circuit breakers must be grid assets. The classification of the judgment results of effective coverage can directly filter out the relevant line information that is not effectively covered due to the unrecognized automatic circuit breaker at the head end of the large branch. Combined with the special GIS single-line diagram for effective coverage, the position of the automatic circuit breaker in question can be directly located and Display the equipment ledger data of the corresponding circuit breaker, lock the ledger problem of the problematic automatic circuit breaker, and then perform one-key correction through the correction function, and automatically correct the ledger data of the problematic automatic circuit breaker to normal data, thereby solving the problem that caused a large The problem ledger data of the asset attribute error of the automatic circuit breaker at the head end of the branch.

(3) Line effective coverage judgment only judges the public line. When the line is a leased line, the effective coverage statistical result will default to No. According to the classification of the judgment result that the line is not effectively covered, filter out the line GIS account data attribute that is a leased line. For the line information that does not carry out effective coverage judgment, the public and private error problems corresponding to the line can be locked through the connected line GIS ledger data, and then one-click correction can be performed through the correction function, and the ledger asset data of the problematic line is automatically corrected to Normal data, so as to solve the problem of account data that causes public line and private line errors.

(4) When calculating the number of medium-voltage subscribers on the line, the public change is counted as 1 household, the special change is counted as 1 household with the same account number, and each of the different account numbers is counted as 1. According to the classification of the judgment results that the lines are not effectively covered, the cause can be filtered out. The GIS one-line diagram with the same account number is double-calculated and the medium voltage exceeds the standard value to form relevant line information that is not effectively covered. Combined with the effective coverage of the special GIS one-line diagram for the special change user label, you can directly locate the user with the same account number. Number information, and then use the correction function to perform one-click correction, and automatically correct the ledger data of the problematic user number to normal data, thereby solving the problem of double counting errors caused by the same account number.

(5) The automatic switch is judged by the TYPE attribute of the switch, but the handcart switch does not have a corresponding automatic TYPE relationship, so it needs to be automatically judged by the IP address of the handcart switch, and is classified according to the judgment result that the line is not effectively covered, and filtered out The relevant line information that is not effectively covered due to the fact that the main line of the line passes through the automatic handcart switch or the head end of the large branch is an automatic handcart switch but has not been identified, combined with the effective coverage of the handcart switch marking of the special GIS one-line diagram, locks the unrecognized automation Handcart switch problem ledger data, locate the IP address ledger data filled in the handcart switch, and then perform one-key correction through the correction function, and automatically correct the handcart switch IP of the problem line to normal data, thereby solving the problem caused by the IP address Handcart switch automation unidentified problem ledger data.

Step S104, correcting the abnormal equipment data.

In this step, the abnormal equipment data is corrected into normal equipment data according to the abnormality type corresponding to the abnormal equipment data by using a preset correction function. Among them, the preset correction function can be the built-in function of the GIS model building software, so as to automatically correct according to the abnormal problem category of the primary equipment data, and solve the problem of missing and wrong writing of GIS model data.

Further, after step S104, return to step S102, continue to locate abnormal device data and automatically correct until the line effective coverage index is met.

It should be noted that (1) through the calculation of effective coverage indicators, the main line/branch line, sub-section switch/connection switch, number of medium-voltage users/number of low-voltage users, grid assets/user assets, etc. of the line GIS model can be directly counted Ledger data and its topology analysis, by analyzing the abnormal points of the effective coverage indicators, combined with the statistics of the relevant ledger data, can quickly determine whether the GIS model data is abnormal, and can quickly locate the GIS model problem data location and autocorrect it.

(2) The effective coverage index judges the main line/branch line, sub-section switch/connection switch, number of medium-voltage users/number of low-voltage users, power grid assets/user assets of the GIS model of the line, and the errors of the GIS model are eliminated as much as possible analyzed out. Therefore, each effective coverage index calculation can analyze a large number of errors in the GIS model, greatly improving the correction efficiency.
