[0002] Substations are an important part of the power system. Their operation involves multiple devices, large amounts of data, and complex relationships. In order to ensure the reliability and safety of the power system, effective operation and maintenance management is required.

[0003] With the development of technology, the application of intelligence and automation in power systems is increasing. In combination with advanced technologies such as artificial intelligence and big data analysis, the intelligence level of operation and maintenance can be effectively improved: using big data technology to process and analyze large amounts of data collected from substations. Through in-depth analysis of this data, insights into equipment performance, trends, and potential failures can be extracted. For example, a substation operation and maintenance method disclosed in announcement number: CN103617501B establishes an intranet system for a production management system and a mobile terminal; generates and stores an electronic operation manual for substation equipment; tests the substation equipment based on the electronic operation manual and generates test results; the mobile terminal sends the test results to the production management system via the intranet system. All data information in this method is transmitted through the intranet system, and its operation process is simple. The production management system can obtain the test results in a timely and accurate manner.

[0004] However, the above substation operation and maintenance inspection method lacks accurate calculation model reference and is not suitable for the evaluation of substation operation and maintenance management.

[0005] Therefore, in response to the above problems, a substation operation and maintenance management evaluation method is urgently needed. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the present invention provides a substation operation and maintenance management evaluation method, which solves the problems of lack of comprehensive numerical evaluation and lack of accurate risk prediction for substation operation and maintenance management.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a substation operation and maintenance management evaluation method, comprising the following steps: based on the acquired substation operation and maintenance information processing, obtaining the substation operation and maintenance status compliance index, and evaluating the current status of substation operation and maintenance management; combining the substation operation and maintenance status compliance index with substation risk-related information to obtain the substation operation and maintenance risk prediction value, and perform risk warning for substation operation and maintenance management; providing an optimization strategy for substation operation and maintenance management based on the substation operation and maintenance risk prediction value.

[0008] Furthermore, the specific process of evaluating the current status of substation operation and maintenance management is as follows: comparing and analyzing the substation operation and maintenance status compliance index with the preset substation operation and maintenance status compliance threshold, and classifying the current status of substation operation and maintenance management. The preset substation operation and maintenance status compliance threshold is expressed as the minimum value of the substation operation and maintenance status compliance index that is acceptable for the current substation operation; when the substation operation and maintenance status compliance index is less than the preset substation operation and maintenance status compliance threshold, it is judged that the current substation operation and maintenance management needs further rectification, and an alarm mechanism is used to send a rectification reminder SMS to the substation operation and maintenance management staff, and the backup power supply is automatically started. At this time, the substation operation and maintenance management level is divided into: unqualified; when the substation operation and maintenance status compliance index is greater than or equal to the preset substation operation and maintenance status compliance threshold, it is judged that there is no risk in the current substation operation and maintenance management for the time being, and further real-time monitoring and risk warning of the substation operation and maintenance management are required. At this time, the substation operation and maintenance management level is divided into: qualified.

[0009] Furthermore, obtaining the substation operation and maintenance status compliance index specifically includes: obtaining substation operation and maintenance information, the substation operation and maintenance information including: substation operation and maintenance management personnel information, substation equipment information, and substation network information; through analysis of the substation operation and maintenance management personnel information, substation equipment information, and substation network information, obtaining the substation operation and maintenance management personnel capability evaluation value, equipment operation management evaluation value, and network security evaluation value, respectively, which are used to evaluate the substation operation and maintenance management personnel's operation and maintenance management capability, the operation and management status of the substation equipment, and the substation network operation safety status, respectively; combining the substation operation and maintenance management personnel capability evaluation value, the equipment operation management evaluation value, and the network security evaluation value, giving weights to the three respectively, performing weighted sum calculation, constructing a substation operation and maintenance status evaluation model, and obtaining the substation operation and maintenance status compliance index.

[0010] Furthermore, the calculation formula for the substation operation and maintenance status compliance index is as follows:

[0011] θ=arctan(η R *t1+η S *t2+η W *t3+1); where θ represents the substation operation and maintenance status compliance index, η R ,η S ,η W They are respectively represented as the capability evaluation value of substation operation and maintenance management personnel, the equipment operation and management evaluation value, and the network security evaluation value. t1, t2, and t3 are respectively represented as the weight factors corresponding to the capability evaluation value of substation operation and maintenance management personnel, the equipment operation and management evaluation value, and the network security evaluation value.

[0012] Furthermore, the specific process of obtaining the capability evaluation value of the substation operation and maintenance management personnel is as follows: obtaining the training cycle of the capability evaluation model of the substation operation and maintenance management personnel; obtaining the information of the substation operation and maintenance management personnel based on the training cycle of the capability evaluation model of the substation operation and maintenance management personnel, the substation operation and maintenance management personnel information including the number of substation operation and maintenance management personnel who have passed the operation and maintenance management capability training, the total number of substation operation and maintenance management personnel who have received the operation and maintenance management capability training, and the average actual work score of all substation operation and maintenance management personnel; based on the comparison of the number of substation operation and maintenance management personnel who have passed the operation and maintenance management capability training and the total number of substation operation and maintenance management personnel who have received the operation and maintenance management capability training, combined with the average actual work score of all substation operation and maintenance management personnel, and assigning weights to each of them, performing weighted summation, and obtaining the capability evaluation value of the substation operation and maintenance management personnel.

[0013] Furthermore, the specific process of obtaining the equipment operation management evaluation value is as follows: obtaining the substation equipment operation management evaluation model training cycle; obtaining substation equipment information based on the substation equipment operation management evaluation model training cycle, the substation equipment information including the substation equipment availability rate, substation equipment maintenance rate, and substation equipment remaining service life; based on the substation equipment availability rate, substation equipment maintenance rate, and substation equipment remaining service life, respectively assign corresponding weights, perform weighted summation, and obtain the equipment operation management evaluation value.

[0015] Furthermore, the specific process of risk warning for substation operation and maintenance management is: comparing and analyzing the substation operation and maintenance risk prediction value with the substation operation and maintenance risk prediction threshold. When the substation operation and maintenance risk prediction value exceeds the substation operation and maintenance risk prediction threshold, it is judged that there is a safety risk in the substation operation and maintenance management, and an alarm mechanism is used to send a reminder SMS to the substation operation and maintenance management staff, providing an optimization strategy. The optimization strategy includes: implementing regular equipment inspection and maintenance plans, implementing a remote monitoring system, and formulating emergency plans.

The substation operation and maintenance status compliance index obtained by weighted summation of the three can provide an effective evaluation of the substation operation and maintenance management status and improve the overall efficiency and reliability of the substation; the substation operation and maintenance risk prediction value obtained by combining the substation operation and maintenance status compliance index with the substation risk-related information takes into account the safety protection score, weather forecast score, and historical fault incidence rate, which helps to predict potential risks and safety issues, thereby formulating corresponding risk management strategies, reducing operation and maintenance risks, and ensuring the stable operation and safety of the substation.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 This is a flow chart of a substation operation and maintenance management evaluation method of the present invention. DETAILED DESCRIPTION

[0023] The embodiment of the present application realizes a comprehensive evaluation of substation operation and maintenance management and accurate prediction of future risks through a substation operation and maintenance management evaluation method.

[0024] The overall idea for the problem in the embodiments of the present application is as follows: obtaining substation operation and maintenance information, including: substation operation and maintenance management personnel information, substation equipment information, and substation network information, and analyzing and obtaining substation operation and maintenance management personnel capability evaluation values, equipment operation management evaluation values, and network security evaluation values, respectively, which are used to evaluate the operation and maintenance management capabilities of substation operation and maintenance management personnel, the operation and management status of substation equipment, and the operation safety status of substation network; then constructing a substation operation and maintenance status evaluation model, obtaining the substation operation and maintenance status compliance index, and evaluating the current status of substation operation and maintenance management; obtaining substation risk-related information, including substation safety protection score, future severe weather forecast score, and historical fault incidence rate; combining the substation safety protection score, future severe weather forecast score, historical fault incidence rate and substation operation and maintenance status compliance index analysis, constructing a substation operation and maintenance risk prediction model, obtaining the substation operation and maintenance risk prediction value, and conducting risk warning for substation operation and maintenance management, thereby providing optimization strategies for substation operation and maintenance management.

[0025] See also Figure 1 The embodiment of the present invention provides a technical solution: a substation operation and maintenance management evaluation method, comprising the following steps: based on the acquired substation operation and maintenance information processing, obtaining the substation operation and maintenance status compliance index, and evaluating the substation operation and maintenance management status; combining the substation operation and maintenance status compliance index with substation risk-related information to obtain the substation operation and maintenance risk prediction value, and performing risk warning for substation operation and maintenance management; providing an optimization strategy for substation operation and maintenance management based on the substation operation and maintenance risk prediction value.

[0026] Specifically, the specific process of evaluating the current status of substation operation and maintenance management is as follows: comparing and analyzing the substation operation and maintenance status compliance index with the preset substation operation and maintenance status compliance threshold, and classifying the current status of substation operation and maintenance management. The preset substation operation and maintenance status compliance threshold is expressed as the minimum value of the substation operation and maintenance status compliance index that is acceptable for the current substation operation. When the substation operation and maintenance status compliance index is less than the preset substation operation and maintenance status compliance threshold, it is judged that the current substation operation and maintenance management needs further rectification, and the alarm mechanism is used to send a rectification reminder SMS to the substation operation and maintenance management staff, and the backup power supply is automatically started. At this time, the substation operation and maintenance management level is divided into: unqualified. When the substation operation and maintenance status compliance index is greater than or equal to the preset substation operation and maintenance status compliance threshold, it is judged that there is no risk in the current substation operation and maintenance management for the time being, and further real-time monitoring and risk warning of the substation operation and maintenance management are required. At this time, the substation operation and maintenance management level is divided into: qualified.

[0027] In this implementation plan, by comparing and analyzing the substation operation and maintenance status with the preset threshold, the system can monitor the operating status of the substation in real time. When the status compliance index is less than the preset threshold, the system automatically triggers corrective measures, including sending an alarm text message to the operation and maintenance personnel and starting the backup power supply, which helps to quickly respond to potential problems and reduce the impact of system failures on power supply; even if the substation operation and maintenance status compliance index is greater than or equal to the preset threshold, the system will further conduct real-time monitoring and risk warning, which means that the system not only pays attention to problems that have occurred, but can also predict potential risks and take preventive measures to improve the reliability and safety of the substation; by dividing the operation and maintenance management levels into qualified and unqualified levels, the system can provide clear assessment and classification for the overall management of the substation, which helps to optimize the operation and maintenance strategy and improve management efficiency.

[0028] Specifically, obtaining the substation operation and maintenance status compliance index specifically includes: obtaining substation operation and maintenance information, which includes: substation operation and maintenance management personnel information, substation equipment information, and substation network information. Through analysis of the substation operation and maintenance management personnel information, substation equipment information, and substation network information, the substation operation and maintenance management personnel capability evaluation value, equipment operation management evaluation value, and network security evaluation value are obtained respectively, which are used to evaluate the operation and maintenance management capability of the substation operation and maintenance management personnel, the operation and management status of the substation equipment, and the substation network operation safety status. Combined with the substation operation and maintenance management personnel capability evaluation value, the equipment operation management evaluation value, and the network security evaluation value, weights are assigned to the three respectively, and a weighted sum calculation is performed. The sum of the three weights is 1. A substation operation and maintenance status evaluation model is constructed to obtain the substation operation and maintenance status compliance index, which intuitively represents the overall operation and maintenance status of the substation, making it easier for managers to make decisions.

[0029] In this implementation plan, by integrating operation and maintenance management personnel information, equipment information and network information, the design provides a comprehensive model for evaluating the operation and maintenance status of the substation, which helps to have a more comprehensive understanding of the health status of the entire system, rather than just focusing on a single aspect. The evaluation values ​​of the three aspects are weighted separately, making the system more flexible and able to adjust the weights according to different needs and priorities based on the actual situation of the substation to reflect the importance of each aspect to the overall operation and maintenance status.

[0030] Specifically, the calculation formula of the substation operation and maintenance status compliance index is as follows: θ = arctan (η R *t1+η S *t2+η W *t3+1); where θ is the substation operation and maintenance status compliance index, which is used to evaluate the current status of substation operation and maintenance management, η R ,η S ,η W They are respectively represented as the capability evaluation value of substation operation and maintenance management personnel, the equipment operation and management evaluation value, and the network security evaluation value. t1, t2, and t3 are respectively represented as the weight factors corresponding to the capability evaluation value of substation operation and maintenance management personnel, the equipment operation and management evaluation value, and the network security evaluation value.

[0031] In this implementation plan, the setting of weight factors corresponding to the substation operation and maintenance management personnel capability assessment value, equipment operation management assessment value, and network security assessment value depends on the specific needs and goals of the substation and the relative importance of each assessment indicator, and can be determined by a comprehensive assessment by professionals in related fields; the substation operation and maintenance status compliance index is a comprehensive assessment indicator that can reflect the quality of the overall operation and maintenance status of the substation. The higher the index value, the better the operation and maintenance status; the lower the index value, the worse the operation and maintenance status.

[0032] Specifically, the specific process of obtaining the capability evaluation value of the substation operation and maintenance management personnel is as follows: obtaining the training cycle of the substation operation and maintenance management personnel capability evaluation model; obtaining the substation operation and maintenance management personnel information based on the training cycle of the substation operation and maintenance management personnel capability evaluation model, wherein the substation operation and maintenance management personnel information includes the number of substation operation and maintenance management personnel who have passed the operation and maintenance management capability training, the total number of substation operation and maintenance management personnel who have received the operation and maintenance management capability training, and the average actual work score of all substation operation and maintenance management personnel; based on the comparison of the number of substation operation and maintenance management personnel who have passed the operation and maintenance management capability training and the total number of substation operation and maintenance management personnel who have received the operation and maintenance management capability training, combined with the average actual work score of all substation operation and maintenance management personnel, and respectively assigning weights, performing weighted summation, the capability evaluation value of the substation operation and maintenance management personnel is obtained, and the calculation formula is: Where η RIt represents the capability evaluation value of substation operation and maintenance management personnel, i represents the training cycle of substation operation and maintenance management personnel capability evaluation model, i=1,2,3,...,m, They are respectively represented as the number of substation operation and maintenance managers who passed the operation and maintenance management ability training in the i-th training, the total number of substation operation and maintenance managers who received the operation and maintenance management ability training, and the average actual work score of all substation operation and maintenance managers, It represents the preset value of the average actual work score of all substation operation and maintenance management personnel, and d1 and d2 represent the weight factors corresponding to the substation operation and maintenance management training ability and actual work ability, respectively.

[0033] In this implementation plan, the number of substation operation and maintenance management personnel who have passed the operation and maintenance management capacity training and the total number of substation operation and maintenance management personnel who have received the operation and maintenance management capacity training are obtained through training records; the average actual work score of all substation operation and maintenance management personnel is obtained through a performance evaluation system of the substation, and the actual work score data of all operation and maintenance management personnel are obtained, and then the average is taken; the setting of the weight factor corresponding to the substation operation and maintenance management training capacity and the actual work capacity is determined by comprehensively considering the specific situation of the substation, business needs and the opinions of the personnel participating in the evaluation, and professionals in the field of operation and maintenance management or experts with rich experience can be invited to participate, and the determination is made through expert evaluation; the preset value of the average actual work score of all substation operation and maintenance management personnel is obtained by referring to relevant industry standards, guidelines or performance indicators of similar substations to obtain a reference value for the average actual work score of operation and maintenance management personnel, and is set in combination with the suggestions of professionals in related fields.

[0034] Specifically, the process of obtaining the equipment operation management evaluation value is as follows: obtaining the training cycle of the substation equipment operation management evaluation model; obtaining substation equipment information based on the training cycle of the substation equipment operation management evaluation model, wherein the substation equipment information includes the substation equipment integrity rate, the substation equipment maintenance rate, and the substation equipment remaining service life; assigning corresponding weights based on the substation equipment integrity rate, the substation equipment maintenance rate, and the substation equipment remaining service life, performing weighted summation, and obtaining the equipment operation management evaluation value. The calculation formula is:

[0035] Where η S It represents the equipment operation management evaluation value, i represents the training cycle of the substation equipment operation management evaluation model, i=1,2,3,...,m, j represents the equipment number of the substation, j=1,2,3,...,uζ 1ij ,ζ 2ij ,ζ 3ij They are respectively represented as the substation equipment integrity rate, substation equipment maintenance rate, and substation equipment remaining service life of the j-th substation equipment in the i-th training, Δζ 3j' represents the rated life of the j-th substation equipment, r1, r2, and r3 represent the weight factors corresponding to the substation equipment integrity rate, substation equipment maintenance rate, and substation equipment remaining service life, respectively.

[0036] In this implementation plan, the equipment availability rate is obtained by deploying sensors and monitoring systems to monitor the status of the equipment in real time, or by conducting regular equipment inspections and patrols to record the status and performance of the equipment; the equipment maintenance rate is obtained by recording the maintenance activities of the equipment by the maintenance team or by using a maintenance management system to track and record all maintenance activities; the remaining service life of the equipment is inferred by detecting the wear and aging of the equipment; the setting of the weight factors corresponding to the substation equipment availability rate, substation equipment maintenance rate, and substation equipment remaining service life depends on the priorities of the substation manager or relevant stakeholders, and is set through comprehensive evaluation by professionals in related fields, where r1+r2+r3=1; the rated life of the substation equipment is obtained from the equipment's user manual, or by professionals in related fields providing a reasonable estimate of the rated life of the equipment based on their own experience and knowledge.

[0037] Specifically, the network security assessment value is obtained by: obtaining the training cycle of the substation network security assessment model; obtaining substation network information based on the training cycle of the substation network security assessment model, wherein the substation network information includes the number of substation network security events and the total number of substation network connections; combining the number of substation network security events and the total number of substation network connections for comparative analysis, to obtain the network security assessment value, and the calculation formula is: Where η W is represented by the network security assessment value, i represents the substation network security assessment model training cycle, i=1,2,3,...,m, β 1i , β 2i They are respectively represented as the number of substation network security events and the total number of substation network connections in the i-th training.

[0038] In this implementation plan, the number of substation network security incidents and the total number of network connections are obtained by deploying a network monitoring system to monitor the activities of the substation network in real time and capture detailed information on network connections, data transmission and other network activities, or by using network monitoring tools to track the source and destination of network connections and detect abnormal activities, including potential network security incidents. They can also be obtained by configuring firewalls and IDS / IPS systems to monitor and record network connections, record connection attempts, blocked events and other network security-related activities; calculating the network security assessment value can visualize the network security status as a specific number, which helps management and security professionals to more intuitively understand the overall health of network security, help to timely discover potential security issues and vulnerabilities, and thus maintain network security.

[0039] Specifically, the specific process of risk warning for substation operation and maintenance management is as follows: compare and analyze the substation operation and maintenance risk prediction value with the substation operation and maintenance risk prediction threshold. When the substation operation and maintenance risk prediction value exceeds the substation operation and maintenance risk prediction threshold, it is judged that there is a safety risk in the substation operation and maintenance management, and an alarm mechanism is used to send a reminder text message to the substation operation and maintenance management staff to provide optimization strategies. The optimization strategies include: implementing regular equipment inspection and maintenance plans to ensure the health of substation equipment, improve the reliability and life of equipment, and reduce the occurrence of unexpected failures; implementing a remote monitoring system to help operation and maintenance personnel monitor the operating status of the substation anytime and anywhere, which helps to detect potential problems in a timely manner and quickly take remote measures to solve some simple failures, reducing dependence on on-site personnel; formulating emergency plans to help respond quickly and orderly when safety incidents occur.

[0040] In this implementation plan, by comparing the substation operation and maintenance risk prediction value with the set threshold, potential safety risks can be perceived in real time, which helps to take timely measures before the problem becomes serious to prevent possible accidents and failures; the alarm mechanism can immediately send a prompt text message to relevant personnel when the operation and maintenance risk exceeds the threshold, helping operation and maintenance managers to understand the problem in time and respond quickly, thereby reducing the impact of potential risks; implementing regular equipment inspection and maintenance plans, implementing remote monitoring systems, and formulating emergency plans will help maintenance personnel formulate targeted response measures, reduce the probability of potential risks, and improve the safety and reliability of substations.

[0041] Specifically, obtaining the substation operation and maintenance risk prediction value specifically includes: obtaining substation risk-related information, the substation risk-related information including the substation safety protection score, future severe weather forecast score, and historical failure rate; combining the substation safety protection score, future severe weather forecast score, historical failure rate and substation operation and maintenance status compliance index analysis to construct a substation operation and maintenance risk prediction model to obtain the substation operation and maintenance risk prediction value.

[0042] In this implementation plan, by integrating the substation safety protection score, future severe weather forecast score, and historical failure rate, a comprehensive assessment of substation risks can be achieved, which helps to more comprehensively understand potential risk sources and improve the management and control of the entire system. The historical failure rate can help discover potential long-term trends and cyclical problems; the substation safety protection score, future severe weather forecast score, historical failure rate and substation operation and maintenance status are analyzed in accordance with the index, which helps to quantify the impact of various indicators on the operation and maintenance status, and helps to more specifically identify potential problems and improvement directions, providing comprehensive risk assessment and prediction for substation operation and maintenance management, and helping to improve the safety, reliability and overall operating efficiency of the system.

[0043] Specifically, the calculation formula for the substation operation and maintenance risk prediction value is as follows: Where σ represents the substation operation and maintenance risk prediction value, which is used to provide risk warning for substation operation and maintenance management; θ represents the substation operation and maintenance status compliance index, which is used to evaluate the current status of substation operation and maintenance management; τ1, τ2, and τ3 represent the substation safety protection score, future severe weather forecast score, and historical failure rate, respectively; κ1, κ2, and κ3 represent the weight factors corresponding to the substation safety protection score, future severe weather forecast score, and historical failure rate, respectively; ι1 and ι2 represent the weight factors corresponding to the substation operation and maintenance status compliance index and substation risk-related information, respectively.

[0044] In this implementation scheme, the substation safety protection score is obtained by collecting safety inspection records and assessment reports of the substation, or by using data recorded by the monitoring system, such as video surveillance, sensor data, etc., to evaluate the operating status of the safety protection equipment. The higher the score, the more complete the substation safety protection measures are. The future severe weather forecast score is obtained by using meteorological data sources, such as weather stations, meteorological satellites, etc., to obtain future weather forecast information. The historical failure rate is obtained by analyzing the maintenance records of substation equipment, including past failures, repairs and maintenance, or by using historical performance data recorded by the data acquisition system to identify possible failure trends in the past. The substation safety protection score, future severe weather forecast score, and weight factors corresponding to the historical failure rate, and the weight factors corresponding to the substation operation and maintenance status compliance index and substation risk-related information are set by professionals in related fields assigning weights to each factor based on their experience and knowledge to reflect its contribution to the safety of the entire system, or by using decision support methods such as AHP to compare the relative importance of different factors between each other to establish a weight matrix setting.

[0045] In summary, this application has at least the following effects: by comprehensively considering the capabilities of operation and maintenance management personnel, equipment operation management and network security, a comprehensive assessment of the operation and maintenance status of the entire substation is obtained, which helps to timely discover and solve potential problems and improve overall efficiency and reliability; taking into account factors such as safety protection scores, weather forecast scores, historical failure rates, etc., a risk prediction model is constructed, which helps to identify potential risks and safety issues in advance, so that corresponding risk management strategies can be formulated to reduce possible losses.
