Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of substation maintenance, in particular to a substation inspection management method and system. BACKGROUND

[0002] With the continuous expansion of the power grid, the number and scale of substations are also increasing. At the same time, as an important form of energy, electricity is crucial to the energy security of the country and the normal operation of society. The implementation of the substation inspection management method and system can improve the stability and reliability of substation equipment, reduce the occurrence of faults and power outages, and thus ensure the safety and reliability of power supply.

[0003] For example, the publication number: CN114444730A discloses a substation periodic inspection management method and system. By presetting an inspection plan, the inspection plan includes inspection time nodes, preset inspection duration, inspection type information, and preset inspection period. Based on the preset inspection plan, the inspection personnel are reminded to perform the inspection work. The actual inspection information corresponding to the inspection work is obtained, and the actual inspection information and the preset inspection plan are compared to generate an inspection result. In this way, based on the preset inspection plan, the inspection personnel can be reminded to perform periodic inspection work on the substation, and the inspection information of the inspection personnel can be supervised in real time, which can improve the inspection supervision and enhance the inspection quality.

[0004] However, this method requires a preset inspection plan, including time nodes, duration, type, and period information. If the actual situation changes, the preset plan is not flexible enough to adapt to changes in the actual situation in a timely manner. By comparing the actual inspection information with the preset inspection plan to generate an inspection result, due to the complexity of the on-site environment, the variability of equipment status, and the influence of human factors, the actual inspection information may have errors, and therefore the accuracy of the inspection result may be affected to some extent. Over-reliance on the execution of the inspection personnel to perform the inspection according to the preset plan and report the actual inspection information affects the supervision and quality of the inspection.

[0033] Specifically, the substation equipment inspection data acquisition module is used to acquire substation equipment state data based on a substation equipment sensor and send the substation equipment state data to the substation inspection data processing subsystem; the substation environment inspection data acquisition module is used to acquire substation working environment data based on a substation environment sensor and send the substation working environment data to the substation inspection data processing subsystem; and the substation inspection task data acquisition module is used to acquire substation inspection task data and send the substation inspection task data to the substation inspection data processing subsystem.

[0034] In this implementation plan, the substation equipment inspection data acquisition module connects to substation equipment sensors to acquire status data of the substation equipment, including operating temperature, operating current, and operating voltage. The substation equipment is sequentially numbered 1, 2, 3...i...n. This data reflects the equipment's operating status and is used for subsequent data processing and analysis. The substation environment inspection data acquisition module connects to substation environment sensors to acquire substation operating environment data, including average environmental temperature, average humidity, and average humidity-pressure.

The substation inspection task data acquisition module acquires substation inspection task data through tasks assigned by superiors, including the number of completed inspection tasks, the required number of inspection tasks, the completion time of inspection tasks, the required inspection time, the area covered by the inspection, and the area covered by the inspection. This data provides the foundation for subsequent inspection data processing and analysis.

[0035] Specifically, the substation inspection data processing subsystem includes a substation equipment inspection data calculation module, a substation environment inspection data calculation module, a substation inspection task data calculation module, and a substation inspection data calculation module. Specifically: the substation equipment inspection data calculation module receives and processes substation equipment status data sent by the substation equipment inspection data acquisition module, calculates the substation equipment anomaly index, and sends it to the substation inspection data calculation module; the substation environment inspection data calculation module receives and processes working environment data sent by the substation environment inspection data acquisition module, calculates the substation working environment anomaly index, and sends it to the substation inspection data calculation module; the substation inspection task data calculation module receives and processes inspection task data sent by the substation inspection task data acquisition module, calculates the substation inspection task anomaly index, and sends it to the substation inspection data calculation module; and the substation inspection data calculation module acquires the substation equipment anomaly index, the substation working environment anomaly index, and the substation inspection task anomaly index, performs comprehensive processing, and calculates the substation inspection anomaly index.

[0036] In this implementation plan, the substation equipment inspection data calculation module is used to process substation equipment status data and calculate the substation equipment anomaly index. The equipment status data includes substation equipment operating temperature, operating current, and operating voltage; and the substation equipment is sequentially numbered 1, 2, 3...i...n. The specific calculation formula for the substation equipment anomaly index is as follows:

[0037]

[0038] In the formula, DA represents the substation equipment anomaly index, used to measure the condition of substation equipment, DW1 is the operating temperature of the i-th substation equipment, and DW i1 DI represents the standard value of the operating temperature of substation equipment. i The operating current of the i-th substation equipment, DI i1 DU represents the standard value of the operating current of the i-th substation equipment. i The operating voltage of the i-th substation equipment, DU i1 δi represents the standard value of the operating voltage of the i-th substation equipment; δ1 represents the weighting factor of the substation equipment operating temperature on the substation equipment anomaly index; δ2 represents the weighting factor of the substation equipment operating current and voltage on the substation equipment anomaly index. A certain number of substation equipment anomaly sample data are collected, and data analysis and modeling are performed using the collected data samples. During the modeling process, regression analysis and feature selection can be used to determine the degree of influence of operating current and voltage on the anomaly index, thereby determining the weighting factor of substation equipment operating current and voltage on the substation equipment anomaly index. The substation environmental inspection data calculation module is used to process substation operating environment data and calculate the substation operating environment anomaly index. The specific calculation formula for the substation operating environment anomaly index is as follows:

[0039]

[0040] In the formula, EA represents the substation operating environment anomaly index, used to assess the substation operating environment condition; ET represents the average substation ambient temperature; ET1 represents the standard value of the average substation ambient temperature; EW represents the average substation ambient humidity; EW1 represents the standard value of the average substation ambient humidity; EQ represents the average substation ambient air pressure; EQ1 represents the standard value of the average substation ambient air pressure. The substation inspection task data calculation is used to process substation inspection task data and calculate the substation inspection task anomaly index. The specific calculation formula for the substation inspection task anomaly index is as follows:

[0041]

[0042] In the formula, TA represents the substation inspection task anomaly index, used to measure the completion status of substation inspection tasks; Tr represents the number of completed inspection tasks; TR represents the prescribed number of inspection tasks; Tm represents the inspection task completion time; TM represents the prescribed inspection task time; Ts represents the completed inspection area; TS represents the prescribed inspection area; ξ1 represents the weight of the number of inspection tasks on the substation inspection task anomaly index; ξ2 represents the weight of the inspection task time on the substation inspection task anomaly index; and ξ3 represents the weight of the inspection area on the substation inspection task anomaly index. A certain number of substation task anomaly sample data are collected, and data analysis and modeling are performed using these data samples. During the modeling process, regression analysis can be used to determine the degree of influence of operating current and voltage on the anomaly index, thereby determining the weighting factors of substation equipment operating current and voltage on the substation equipment anomaly index.

[0043] Specifically, the formula for calculating the substation inspection anomaly index is as follows:

[0044] λ=DA*φ1+EA*φ2+TA*φ3;

[0045] In the formula, λ represents the substation inspection anomaly index, which is used to measure the degree of substation inspection anomalies; DA represents the substation equipment anomaly index; EA represents the substation working environment anomaly index; TA represents the substation inspection task anomaly index; φ1 represents the weighting factor of the substation equipment anomaly index on the substation inspection anomaly index; φ2 represents the weighting factor of the substation working environment anomaly index on the substation inspection anomaly index; φ3 represents the weighting factor of the substation inspection task anomaly index on the substation inspection anomaly index; and φ1+φ2+φ3=1.

[0046] In this implementation plan, by calculating the substation inspection anomaly index, various inspection anomalies can be comprehensively considered to form a comprehensive evaluation index. This allows for a more comprehensive understanding of the substation's operational status, the identification of potential problems and hidden dangers, and helps assess and monitor the substation's operational status, promptly identify and resolve potential problems, and ensure the safe and stable operation of the substation. Based on historical data and statistical analysis of the substation inspection anomaly index, the influence of the substation equipment anomaly index, the substation working environment anomaly index, and the substation inspection task anomaly index is analyzed, and weighting factors are determined accordingly.

[0047] Specifically, the substation inspection anomaly subsystem includes a substation inspection anomaly analysis module and a substation inspection anomaly calculation module. The substation inspection anomaly analysis module compares the substation inspection anomaly index sent by the substation inspection data processing subsystem with a standard value for the substation inspection anomaly index. If the substation inspection anomaly index is greater than the standard value, it sends the substation inspection anomaly index to the substation inspection anomaly calculation module. The substation inspection anomaly calculation module processes the substation inspection anomaly index sent by the substation inspection anomaly analysis module and calculates the substation inspection and maintenance compliance coefficient.

[0048] In this implementation plan, the substation inspection anomaly analysis module receives the substation inspection anomaly index from the substation inspection data processing subsystem and compares it with a preset standard value. If the substation inspection anomaly index is found to be greater than the standard value, it means that an anomaly exists during the inspection. This module then sends the anomaly index to the substation inspection anomaly calculation module for further processing. The substation inspection anomaly calculation module receives the substation inspection anomaly index from the substation inspection anomaly analysis module, processes and calculates it, and calculates the substation inspection and maintenance compliance coefficient based on the anomaly index. This coefficient can be used to evaluate the inspection and maintenance status of substation equipment, assisting in subsequent maintenance decisions and planning.

[0049] Specifically, the formula for calculating the compliance coefficient of substation inspection and maintenance is as follows:

[0050]

[0051] In the formula, γ represents the substation inspection and maintenance compliance coefficient, which is used to assess whether the substation inspection meets the maintenance standards; λ represents the substation inspection anomaly index; λ1 represents the standard value of the substation inspection anomaly index; and Δλ represents the allowable deviation of the substation inspection anomaly index.

[0052] In this implementation plan, a maintenance compliance coefficient is calculated to assess whether substation inspections meet maintenance standards. The maintenance compliance coefficient reflects the consistency between actual and planned maintenance work; a higher coefficient indicates better compliance with maintenance requirements. Based on statistical analysis results and a risk assessment of substation operation, a reasonable allowable value for the inspection anomaly index deviation is determined. This allowable value reflects the reasonable range of the inspection anomaly index under normal operating conditions.

[0053] Specifically, the substation maintenance management subsystem includes a substation inspection and maintenance analysis module and a substation inspection and maintenance information reporting module. The substation inspection and maintenance analysis module compares the substation inspection and maintenance compliance coefficient sent by the substation inspection anomaly subsystem with a threshold value. When the compliance coefficient exceeds the threshold, it sends the compliance information to the substation inspection and maintenance information reporting module. The substation inspection and maintenance information reporting module then sends maintenance information to substation maintenance management personnel based on the acquired compliance information.

[0054] This implementation plan, through monitoring and analyzing the substation inspection and maintenance compliance coefficient, can promptly identify problems and safety hazards in inspection and maintenance work, providing more reliable protection for substation operation. Using the substation inspection and maintenance management subsystem can improve maintenance efficiency and reduce the time and cost of inspection and maintenance work. When the substation inspection and maintenance compliance coefficient exceeds a threshold, maintenance information is automatically sent, enabling rapid information transmission and processing. Furthermore, by monitoring and analyzing the inspection and maintenance compliance coefficient, maintenance quality can be improved by promptly identifying problems and deficiencies in maintenance work, providing maintenance personnel with opportunities for improvement, and preventing similar problems in future inspection and maintenance work.

[0055] Specifically, the process of sending maintenance information to substation maintenance management personnel is as follows: A database and information authorization code for maintenance management personnel are created, accepting name, mobile phone number, and email address as parameters; forms and text boxes are created, providing users with input of maintenance information, email address, and corresponding authorization code; when the substation inspection and maintenance information reporting module receives substation inspection and maintenance compliance information, it verifies the information authorization code and promptly sends the maintenance information to the substation maintenance management personnel via email and SMS.

[0056] In this implementation plan, by creating a database of maintenance management personnel and information authorization codes, it is ensured that only authorized personnel can receive and process maintenance information. This guarantees the security and reliability of the information. When the substation inspection and maintenance information reporting module receives qualified information, the system can automatically send emails and SMS messages to the substation maintenance management personnel by verifying the information authorization code. This enables real-time notification and timely response, allowing management personnel to quickly obtain relevant information and take necessary actions. By sending maintenance information to the maintenance management personnel's email and mobile phone, delays and inaccuracies in information transmission can be avoided. Management personnel can view and reply to maintenance information anytime, anywhere, improving communication and work efficiency. The sent maintenance information is recorded and archived for easy subsequent retrieval and tracking. This establishes a complete maintenance information history, providing a basis for subsequent analysis and decision-making. By creating forms and text boxes, users can directly enter the content of maintenance information and provide their email address and authorization code. The system can automatically verify and send information, reducing the possibility of manual operation and human error.

[0057] Specifically, the process of statistically analyzing substation inspection data and generating inspection reports and substation equipment operation reports is as follows: Substation inspection data sent by the substation inspection data acquisition subsystem is stored in a database; statistical methods are used to analyze the inspection data, calculating equipment failure rate, mean time between failures (MTBF), and mean time to repair (MTBT), and the statistically analyzed data is imported into Tableau; the operating time, operating cost, and maintenance cost of substation equipment are statistically analyzed, and the statistically analyzed data is imported into Tableau; and Tableau is used to generate inspection reports and substation equipment operation reports.

[0058] In this implementation plan, substation inspection data is stored in a database, enabling centralized management and persistent storage. This facilitates subsequent data analysis and report generation while ensuring data security and reliability. By statistically analyzing the inspection data, the failure rate can be calculated by determining the number of failures and total operating time for each device based on fault records and equipment operating time records. The mean time between failures (MTBF) and mean time to repair (MTBR) are also calculated using statistical methods. Based on the fault records and repair time records in the inspection data, the total MTBF, total repair time, and number of failures for each device are calculated, leading to the corresponding MTBF and MTBR. These indicators can assess the operational status and stability of the equipment, helping managers develop reasonable maintenance plans and optimize operation and maintenance strategies.

[0059] A substation inspection management method includes the following steps: S1. Acquiring substation inspection data, statistically analyzing the substation inspection data, and generating inspection reports and substation equipment operation reports; S2. Processing the substation inspection data based on the substation inspection data and calculating the substation inspection anomaly index; S3. Analyzing the degree of substation inspection anomalies and calculating the substation inspection and maintenance compliance coefficient based on the analysis results; S4. Analyzing the substation inspection and maintenance compliance coefficient and sending maintenance information to substation maintenance management personnel based on the analysis results.

[0060] In summary, this application has at least the following effects:

[0061] A substation inspection management method and system are disclosed. By calculating a substation inspection anomaly index, the degree of anomalies during substation inspections can be reflected. Analyzing the anomaly index can help identify equipment failures, missed inspections, and other issues, providing a reference for maintenance decisions. Calculating a substation inspection-maintenance compliance coefficient reflects the quality and timeliness of inspection and maintenance work. Analyzing the compliance coefficient can determine whether inspection and maintenance work is adequate, providing a basis for subsequent improvement. Based on the analysis results of the inspection-maintenance compliance coefficient, maintenance information can be sent to substation maintenance management personnel, reminding them to promptly handle equipment failures and inspection anomalies, ensuring the safe and stable operation of the substation, improving data accuracy and real-time performance, reducing errors and delays caused by manual operations, prioritizing anomalies according to their severity to help determine maintenance plans and resource allocation. Through the maintenance management subsystem, the efficiency and quality of maintenance work can be improved, reducing the impact of equipment failures on power grid operation.
