[0002] With the rapid development of modern society, the safety, stability and reliability of the power system, as one of the basic infrastructures for social operation, are particularly important. However, with the expansion of the scale of the power grid and the increasing complexity of power equipment, power information management faces unprecedented challenges. Traditional power information management methods often rely on manual inspections and regular maintenance, which is not only inefficient, but also difficult to accurately capture the real-time status of power equipment. Especially in the face of sudden failures or emergencies, they are often slow to respond and unable to quickly take effective countermeasures.

[0003] Specifically, when maintenance resources are limited, how to reasonably allocate maintenance resources has become a major problem. Traditional methods often perform maintenance based on experience or fixed cycles, and cannot be flexibly adjusted according to the actual operating conditions of the equipment, resulting in over-maintenance or under-maintenance of some equipment;

[0004] Secondly, due to unreasonable maintenance plans and personnel allocation, coupled with the lack of a scientific maintenance priority assessment mechanism, the maintenance efficiency is low, key equipment cannot be maintained in a timely manner, affecting the overall operation safety of the power system. In addition, the skill levels and experience of safety maintenance personnel vary greatly, but under the traditional model, there is often no reasonable matching mechanism to ensure that the most suitable candidates are sent to where they are most needed, which may lead to inefficiency and increased safety risks.

BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 A flow chart of a power information management method provided by the present invention. DETAILED DESCRIPTION

[0038] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0039] First, the professional terms involved in this application are explained.

[0040] Geographic Information System (GIS) technology: is specifically used for collecting, storing, managing, calculating, analyzing, displaying and describing geographic spatial data.

[0041] Weighted summation method: It is to assign different weights to different data or factors, then multiply and sum them, and finally get the weighted average. This method can more accurately reflect the impact of each factor on the final result and provide a more accurate reference for decision-making.

[0042] CRC check: It is an error detection technology widely used in data transmission and storage. It uses the principle of division and remainder to check the integrity of data by adding redundant information to ensure that the data is not damaged during transmission or storage.

[0043] Example

[0044] like Figure 1 As shown, a power information management method includes the following steps:

[0045] S100, dividing a plurality of monitoring areas based on the location distribution of the power equipment, and evaluating the plurality of monitoring areas based on the importance of the power equipment to obtain evaluation results of the monitoring areas.

[0046] Specifically, according to the geographical distribution of power equipment (such as transformers, switch stations, transmission lines, etc.) in the power grid, the entire power network is divided into several areas for easy management and monitoring using geographic information system (GIS) technology, and the importance of power equipment in each monitoring area is evaluated. The specific evaluation basis includes factors such as the power supply load of the power equipment, the scope of fault impact, the number of key users, and the degree of equipment obsolescence. By combining these factors, an evaluation result is given to each monitoring area, which is usually a score or grade, which is used to distinguish the priorities of different monitoring areas in subsequent decision-making.

[0047] For example, a power grid is divided into five monitoring areas, where area A contains multiple large substations and high-voltage transmission lines, and is the core area of ​​urban power supply. Therefore, it is assessed as the highest level and marked as level A, while area E is mainly a low-voltage distribution network with a relatively small impact range, and is assessed as level E. Such division and assessment provide important basis for subsequent resource allocation and maintenance planning.

[0048] S200, receiving the power parameter monitoring data of each monitoring area through a preset processing center, and preprocessing the power parameter monitoring data of each monitoring area to obtain the preprocessed monitoring data of each monitoring area.

[0049] Specifically, the preset processing center receives power parameter monitoring data from sensors, smart meters and other equipment arranged in each monitoring area. These data include voltage, current, power factor and other real-time information. After receiving the data, the processing center performs preprocessing operations, including data cleaning (removing noise and outliers), data compression (reducing storage and transmission costs), data conversion (unified format, unit), etc., to ensure the accuracy and efficiency of subsequent analysis. Through preprocessing, useless information can be eliminated and key data can be retained, providing a high-quality data foundation for subsequent analysis and decision-making.

[0050] For example, if a smart meter in a monitoring area uploads a data record containing abnormal voltage fluctuations, in the preprocessing stage, the integrity and rationality of the record are first checked. If the data is found to be out of the normal range or inconsistent with the data of other devices, it is marked as an outlier and corrected or eliminated.

[0051] S300, respectively setting safety threshold sections of power parameters for each monitoring area, specifically including primary safety threshold sections and advanced safety threshold sections, and determining whether the power parameters in the pre-processed monitoring data belong to the primary safety threshold section or the advanced safety threshold section.

[0052] Specifically, two levels of safety threshold segments are set for the power parameters in each monitoring area: a primary safety threshold segment and an advanced safety threshold segment; the primary threshold usually represents the normal fluctuation range of equipment operation, while the advanced threshold is set at the critical point that may cause equipment failure or affect the stability of the power grid; and the power parameters in the preprocessed monitoring data are compared with these thresholds to determine which segment the power parameters are in.

[0053] For example, taking the transformer temperature of a substation as an example, its primary safety threshold is set at 80°C, indicating that the transformer operates normally below this temperature; and the advanced safety threshold is set at 90°C. Once the temperature approaches or exceeds this value, it indicates that the transformer may be at risk of overheating and requires immediate attention.

[0054] S400. In response to the judgment result that the power parameters in the pre-processed monitoring data belong to the advanced safety threshold segment and the primary safety threshold segment, combined with the evaluation result of the monitoring area, the maintenance priority is assigned to the power equipment in each monitoring area to obtain the maintenance level of the power equipment in each monitoring area.

[0055] Specifically, based on the judgment result of whether the power parameters in the pre-processed monitoring data belong to the advanced safety threshold section or the primary safety threshold section, combined with the evaluation results of the monitoring area, the maintenance priority of the power equipment in each monitoring area is comprehensively evaluated, and the maintenance resources will be arranged first in the area with high priority. By setting the maintenance priority based on the equipment status and regional importance, it can be ensured that with limited maintenance resources, the problems that have the greatest impact on the operation of the power system are solved first, the stability and reliability of the overall power grid are improved, the operation safety of the power system is significantly improved, and key equipment is ensured to be maintained in a timely manner.

[0056] For example, if the temperature of a transformer in area A (high importance) continues to approach the advanced safety threshold, while a device in area E (low importance) only slightly exceeds the primary threshold, the system will prioritize the maintenance of the transformer in area A.

[0057] S500. Evaluate the level of safety maintenance personnel according to their skills and length of service, and match the power equipment maintenance level of each monitoring area with safety maintenance personnel of corresponding level based on the evaluation results of the safety maintenance personnel.

[0058] Specifically, first conduct a level assessment of the safety maintenance personnel based on their skill level, length of service and other factors, and divide the maintenance personnel into different levels, such as junior, intermediate and senior. Establish clear matching principles to ensure that maintenance tasks can be assigned to the most suitable safety maintenance personnel. The matching principles specifically include matching the general level, important level and emergency level of maintenance priority with junior, intermediate and senior maintenance personnel; assign maintenance tasks to designated safety maintenance personnel through system notification or manual coordination, and confirm whether they accept the task. During the execution of the maintenance task, continuously monitor the progress of the task and the working status of the safety maintenance personnel. If it is found that the task is difficult to execute or there is a safety hazard, the maintenance plan should be adjusted or additional support personnel should be dispatched in a timely manner.

[0059] First, the monitoring area is divided and evaluated in step S100 to identify the area where the key power equipment is located; in step S300, the safety threshold section of the power parameters is set to monitor in real time whether the power parameters are within the safe range; and then in step S400, the power equipment is given maintenance priority based on the monitoring data and the regional evaluation results to ensure that the key power equipment can be repaired first in case of abnormalities, thereby improving system safety and ensuring that key equipment is maintained in a timely manner.

[0060] In step S400, based on the maintenance priority of the power equipment, a maintenance level is allocated to the power equipment in each monitoring area, which helps to optimize the allocation of maintenance resources and avoid blind maintenance; in step S500, according to the level evaluation results of the safety maintenance personnel, appropriate maintenance personnel are allocated to the power equipment in each monitoring area, thereby improving the targetedness and efficiency of maintenance, and further optimizing the allocation of maintenance resources, improving maintenance efficiency and effectiveness, and avoiding waste of resources.

[0061] The power information management method provided by the present invention provides comprehensive and accurate data support for the management by collecting, processing and analyzing the power parameter monitoring data, combining the evaluation results of the monitoring area and the maintenance priority of the power equipment. These data supports enable the management to make scientific decisions based on the data, thereby enhancing the decision-making support capabilities of the power enterprise.

[0062] In the specific implementation process, the step S100 specifically includes the following steps:

[0063] S101. Collect location information of all power equipment, including longitude and latitude, and the grid area to which they belong.

[0064] Specifically, the location information of all key equipment in the power system is collected, including the specific locations of power plants, substations, transmission lines, distribution transformers, switch stations and other equipment. The collected information records the longitude and latitude coordinates of each power equipment in detail. At the same time, it is also necessary to record the power grid area to which each device belongs, which helps to understand the location and function of the equipment in the power grid.

[0065] S102. Use geographic information system to divide power equipment into several monitoring areas.

[0066] Specifically, the Geographic Information System (GIS) technology is used to take the collected location information of power equipment as input to divide the monitoring area, and the monitoring area is automatically generated according to the preset division rules, including administrative regions, power grid structure, equipment density, etc.

[0067] S103. For each monitoring area, the importance of the power equipment in the monitoring area is evaluated based on the power supply load of the power equipment, the scope of fault impact, the number of key users, and the age of the equipment.

[0068] Specifically, for each evaluation factor of the power supply load of the power equipment, the scope of fault impact, the number of key users, and the degree of equipment ageing, set specific scoring standards, and convert the importance of each factor into a specific value through quantitative scoring to facilitate subsequent comprehensive evaluation. Among them, the quantitative scoring method is to quantitatively score the importance of power equipment, which is the process of converting abstract concepts (such as power supply load, scope of fault impact, number of key users, degree of equipment ageing, etc.) into specific and comparable values.

[0069] S104. Comprehensively evaluate the power supply load of the power equipment, the scope of fault impact, the number of key users, and the age of the equipment to obtain a comprehensive evaluation result for each monitoring area.

[0070] Specifically, the scores of various evaluation factors such as power supply load, fault impact range, number of key users, and equipment age are integrated. According to the scores of each evaluation factor, a weighted sum method is used to calculate the comprehensive evaluation result to obtain the comprehensive evaluation result of each monitoring area.

[0071] In the specific implementation process, the step S200 specifically includes the following steps:

[0072] S201. Receive power parameter monitoring data from each monitoring area through a processing center with a preset communication protocol, including voltage, current, and power factor.

[0073] Specifically, a suitable communication protocol (such as Modbus or IEC 61850) is selected, and the processing center receives the power parameter monitoring data from the monitoring area through its communication interface, including serial port, network port and wireless module. During the receiving process, the processing center performs preliminary analysis on the power parameter monitoring data according to the communication protocol to verify the integrity and correctness of the power parameter monitoring data. If the power parameter monitoring data does not meet the protocol requirements or contains errors, the processing center will refuse to receive the data and send an error prompt or request retransmission to the monitoring area.

[0074] S202, pre-processing the power parameter monitoring data of each monitoring area, specifically including data verification, data cleaning and format conversion.

[0075] Specifically, the processing center verifies the received data according to the verification method defined in the communication protocol, specifically CRC verification. The processing center uses statistical methods and data mining technology to conduct in-depth analysis of the received data to identify and process those data points that do not conform to conventions or logic. After receiving the data, the processing center needs to convert the format to ensure the consistency and processability of the data.

[0076] In the specific implementation process, the step S300 specifically includes the following steps:

[0077] S301. Based on the technical specifications and safety standards of the power equipment, primary safety threshold sections and advanced safety threshold sections are respectively set for the power parameters of each monitoring area.

[0078] Specifically, based on technical specifications and safety standards, a primary safety threshold segment is set for each power parameter of the power equipment. The primary safety threshold segment is set to the parameter fluctuation range when the equipment is operating normally, allowing a certain degree of fluctuation, but not exceeding the limit of long-term stable operation of the equipment. In this embodiment, for voltage parameters, the primary safety threshold segment is set to within ±5% of the rated voltage; an advanced safety threshold segment is set to capture abnormal conditions that may immediately threaten equipment safety or grid stability. In this embodiment, for current parameters among the power parameters, the advanced safety threshold segment is set to more than 120% of the rated current.

[0079] S302, comparing the power parameters in the pre-processed monitoring data with the primary safety threshold segment and the advanced safety threshold segment respectively, and determining whether the power parameters in the pre-processed monitoring data belong to a specific segment within the normal range, the primary safety threshold segment, and the advanced safety threshold segment.

[0080] In the specific implementation process, the step S400 specifically includes the following steps:

[0081] S401. Determine the factors for the maintenance priority of power equipment, including the power parameter threshold attribution weight, the threshold attribution factor and the monitoring area importance weight.

[0082] Specifically, determine the power parameter threshold attribution weights representing the degree of impact on equipment safety and grid stability when different power parameters (such as voltage, current, power factor, etc.) exceed their set thresholds, the threshold attribution factors representing the risk level after the power parameters exceed the thresholds, and the monitoring area importance weights.

[0083] S402. Based on the factors of power equipment maintenance priority, the comprehensive maintenance priority score of the power equipment is calculated by weighted summation, and the maintenance priority of the power equipment in each monitoring area is divided based on the score, wherein the maintenance priority is divided specifically into general level, important level and emergency level.

[0084] In the specific implementation process, the step S500 specifically includes the following steps:

[0085] S501. Evaluate the skill level and length of service of safety maintenance personnel, and classify them into different technical levels based on the evaluation scores, including primary, intermediate and senior technical levels.

[0086] Specifically, according to the evaluation expression: Evaluation score = skill level test score × 0.6 + length of service × 0.4, the safety maintenance personnel are evaluated in terms of skill level and length of service, and an evaluation score below 60 is set as elementary, an evaluation score between 60 and 80 is set as intermediate, and an evaluation score above 80 is set as advanced.

[0087] S502. Match the safety maintenance personnel of the corresponding level according to the maintenance level of the power equipment in each monitoring area, specifically matching the general level, important level and emergency level of the maintenance priority with primary, intermediate and senior maintenance personnel.
