Description

Technical Field

[0001] The present invention relates to a priority calculation system and method for a comprehensive work order, belonging to the technical field of power system operation and maintenance services. Background Art

[0002] With the development of a new generation of electricity consumption information collection systems, high-frequency, full-volume data collection has been achieved, improving the ability to analyze user electricity consumption data and enabling real-time monitoring of business modules such as data collection management, online metering monitoring, line loss monitoring, and anti-electricity theft monitoring. However, the various anomalies generated by real-time diagnosis and analysis of each business module resulted in a large number of maintenance work orders for operations and maintenance personnel. Furthermore, the generation time of anomalies was inconsistent across business modules, making it difficult for operations and maintenance personnel to properly plan work orders.

[0003] Currently, the key to metrology work is to be guided by business needs, integrating and collecting on-site work orders for operations and maintenance, metering exception handling, and line loss management. These work orders are then consolidated into a comprehensive work order, enabling a "one-stop" solution for all metering-related issues, reducing duplicate work orders and improving operational efficiency. In response to the concept of "one-stop" solution, we will follow the principle of dividing comprehensive work orders by station area, develop a comprehensive work order processing mechanism, and propose a scientific assessment method for the priority of comprehensive work orders. This will ensure the standardization and normalization of comprehensive work order processing and address the concerns of relevant operations and maintenance personnel regarding the priority handling of comprehensive work orders. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a system and method for calculating the priority of a comprehensive work order, which can solve the problem of operation and maintenance personnel handling the priority of the comprehensive work order and effectively improve operation efficiency.

[0005] To achieve the above object, the present invention is implemented by adopting the following technical solutions:

[0006] In a first aspect, the present invention provides a method for calculating the priority of a comprehensive work order, comprising:

[0007] Determine the primary and secondary factors of the priority of the comprehensive work order and the weight of each factor;

[0008] Obtain the data of the secondary elements and normalize the data of different dimensions in the secondary elements;

[0009] Calculate the priority of the first-level elements;

[0010] The priority of the comprehensive work order is calculated using weighted accumulation, and the priority of the comprehensive work order is divided into levels.

[0011] Furthermore, the first-level elements of the comprehensive work order priority are divided into: abnormality type elements, substation capacity elements, user type elements and equipment type elements, and the second-level elements are divided into: abnormality type elements include collection abnormalities, metering abnormalities, anti-electricity theft, line loss abnormalities and patrol equipment; substation capacity elements include substation capacity and average substation capacity; user type elements include high-voltage users, low-voltage residential users and low-voltage non-residential users; equipment type elements include electricity meters and terminals.

[0012] Furthermore, the data of the secondary elements include: the number of various types of abnormalities occurring every day in the abnormality type element, the capacity of the substation and the average substation capacity in the substation capacity element, the total number of user types under the substation in the user type element, and the total number of device types under the substation in the device type element.

[0013] Furthermore, the data of different dimensions in the secondary factors are normalized, including:

[0014] The normalized calculation formula for the number of abnormal types, user types, and device types in the secondary factors is as follows:

[0015]

[0016] Among them, N′ ni N is the normalized number of abnormal types, user types, or device types. ni is the number of anomaly types, user types, or device types before normalization.

[0017] The normalized calculation formula for the capacity of the substation is:

[0018]

[0019] Among them, N′ 21 is the normalized capacity of the substation, N 21 is the capacity of the area before normalization, is the average area capacity.

[0020] Furthermore, the normalized data of the secondary factors are multiplied by the weight of the corresponding secondary factors, and then the priority of the primary factors is obtained by accumulating the data. A larger value represents a higher priority. The calculation formula is as follows:

[0021]

[0022] Among them, R n is the priority of the first-level element, I ni is the weight of the corresponding secondary factor, N′ ni The normalized number of exception types, user types, or device types.

[0023] Furthermore, the priority of the comprehensive work order is calculated using weighted accumulation, including: multiplying the priority of the first-level factor by the corresponding weight, and then accumulating them. The calculation formula is as follows:

[0024] R=R1*w1+R2*w2+R3*w3+R4*w4

[0025] Among them, R is the priority of the comprehensive work order, R1 is the priority of the abnormal type factor, R2 is the priority of the station capacity factor, R3 is the priority of the user type factor, R4 is the priority of the equipment type factor, w1 is the weight of the abnormal type factor, w2 is the weight of the station capacity factor, w3 is the weight of the user type factor, and w4 is the weight of the equipment type factor.

[0026] Furthermore, the priority of comprehensive work orders is divided into levels, including:

[0027] In response to a signal that the priority level of the integrated work order is R≥10, the integrated work order level is level I;

[0028] In response to the signal that the priority level of the integrated work order is 6≤R<10, the integrated work order level is level II;

[0029] In response to the signal that the comprehensive work order priority is 0≤R<6, the comprehensive work order level is level III.

[0030] In a second aspect, the present invention provides a priority calculation system for a comprehensive work order, comprising:

[0031] Factor determination module: used to determine the primary and secondary factors of the priority of the comprehensive work order and the weight of each factor;

[0032] Normalization module: used to obtain the data of secondary elements and normalize the data of different dimensions in the secondary elements;

[0033] Priority calculation module: used to calculate the priority of the first-level elements;

[0038] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, which implements the steps of any of the above methods when executed by a processor.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The present invention calculates the priority of the first-level elements by the importance of different types of elements in the comprehensive work order, and then obtains the priority of the comprehensive work order by weighting. This method can accurately evaluate the priority processing order of the comprehensive work order. The present invention fully considers the importance of the abnormal type, area capacity, user type, and equipment type of the area in the comprehensive work order based on the area, and calculates the priority of the comprehensive work order based on this. It can effectively prioritize the processing of higher-level comprehensive work orders, which helps operation and maintenance personnel to reasonably arrange the work order processing plan to improve the efficiency of work order operations.

[0042] Figure 2 This is a flowchart of a calculation method for determining the priority of a comprehensive work order provided in Example 1 of the present invention. DETAILED DESCRIPTION

[0043] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0044] Example 1:

[0045] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Figure 1 The following is a schematic diagram of the implementation steps of the calculation method for determining the priority level of the comprehensive work order, which specifically includes the following four steps:

[0046] S1. Determine the primary and secondary factors and weights of each factor for the priority of the comprehensive work order:

[0047] S101. First, determine the primary and secondary factors of the comprehensive work order priority:

[0048] A comprehensive work order is a work order generated on a per-zone basis for various user anomalies. Because comprehensive work orders are based on zones and handle user anomalies, the first-level factors of the priority of comprehensive work orders are divided into: anomaly type factor, zone capacity factor, user type factor, and equipment type factor, considering the four aspects of the power supply area of ​​the zone: equipment, users, anomalies, and zones. The second-level factors are divided as follows:

[0049] (1) Abnormal type elements include: collection abnormality, metering abnormality, anti-theft electricity, line loss abnormality, and patrol equipment;

[0050] (2) Substation capacity factors include: substation capacity, average substation capacity;

[0051] (3) User type elements include: high-voltage users, low-voltage residential users, and low-voltage non-residential users;

[0052] (4) Equipment type elements include: electricity meter and terminal.

[0053] S102. Determine the weights of the primary and secondary factors by conducting expert panel discussions and analysis, as shown in the following table:

[0054]

[0055] S2. Obtain the data of the secondary elements and normalize the data of different dimensions in the secondary elements:

[0056] S201. First, obtain the data of the secondary elements:

[0057] The abnormality type element is used to obtain the number of various abnormalities that occur each day; the area capacity element is used to obtain the capacity of the area and the average area capacity (the average area capacity in this invention is the average capacity of all areas of the power supply unit where the area is located); the user type element is used to obtain the total number of each user type under the area; the equipment type element is used to obtain the total number of each equipment type under the area; as shown in the following table:

[0058]

[0059]

[0060] S202. Next, normalize the data of the secondary elements:

[0061] Secondary factors previously had different dimensional units. To eliminate the impact of different dimensions on the calculation results, data normalization is required. The normalized calculation formula for the number of abnormal types, user types, and device types in the secondary factors is as follows:

[0062]

[0063] The normalized calculation formula for the capacity of the substation is:

[0064]

[0065] S3. Calculate the priority of the first-level elements:

[0066] In order to reflect the importance of different types of factors, the patent introduces different weights for secondary factors. The normalized data of the secondary factors are multiplied by the corresponding weights of the secondary factors, and then the priority of the primary factors is obtained by accumulation. The larger the value, the higher the priority. The calculation formula is as follows:

[0067]

[0068] Among them, R n is the priority of the first-level element, I ni is the weight of the corresponding secondary factor, N′ ni The normalized number of exception types, user types, or device types.

[0069] S4. Calculate the priority of the integrated work order:

[0070] S401. Calculate the priority of the integrated work order:

[0071] The priority of the comprehensive work order is calculated using weighted accumulation. The priority of the first-level factor is multiplied by the corresponding weight and then accumulated. The calculation formula is as follows:

[0072] R=R1*w1+R2*w2+R3*w3+R4*w4

[0073] S402. Priority levels for integrated work orders. A higher priority level for integrated work orders indicates a higher level. The determination method is as follows:

[0074]

[0075] Figure 2 The flowchart of the calculation method for determining the priority of the comprehensive work order is as follows: first, determine the first-level and second-level factors for calculating the priority of the comprehensive work order, and configure the weight coefficient of the first-level factor and the weight of the second-level factor. The factors mainly include: abnormal type factors (acquisition abnormality, metering abnormality, anti-theft electricity, line loss abnormality, patrol equipment), substation capacity factors (substation capacity, average substation capacity), user type factors (high-voltage users, low-voltage residential users, low-voltage non-residential users), and equipment type factors (meters, terminals). The calculation process is as follows: first, count the specific number of each factor in the second-level factor, and finely normalize the data of different dimensions of the second-level factor to obtain N′ ni, and then according to the importance of different types of factors, the normalized data N′ of the secondary factors ni Multiply by the weight of the corresponding element I ni , and then accumulate to get the priority R of the first-level element n , further use weighted accumulation to calculate the priority of the comprehensive work order, then multiply the priority of the first-level factor by the corresponding weight coefficient, and then accumulate to obtain the priority R of the comprehensive work order, and then determine the level of the comprehensive work order according to the priority of the comprehensive work order. When R ≥ 10, the level of the comprehensive work order is Level I; when 6 ≤ R < 10, the level of the comprehensive work order is Level II; when 0 ≤ R < 6, the level of the comprehensive work order is Level II, and the process ends.

[0076] In summary, the present invention aims to solve the problems that the data collected by the smart meter on the user side may be missing or abnormal, and the feedback data is inconsistent with the voltage sequence of the low-voltage side of the transformer. The method adopts a specific data completion and over-limit verification correction method to verify and improve the low-voltage side voltage sequence of the transformer in the substation and the user voltage sequence. The geometric distance is calculated for the processed voltage sequence to extract the correlation features between the transformer sequence and the user voltage sequence, and then the transformers and users are clustered according to the correlation features, and finally the household-transformer relationship is identified.
