Description

Technical Field

[0001] The present invention relates to the technical field of power system management, and in particular to a method for deploying a highly reliable metering device before a disaster. Background Art

[0002] In today's society, the stability of power supply is crucial to people's production and life. However, the frequent occurrence of natural disasters, especially floods, has brought huge challenges to the power system. Floods are characterized by suddenness and destructive power. Once they occur, public network communication base stations and power lines often suffer large-scale damage.

[0003] In this case, the power information collection system faces a serious dilemma. Due to communication interruption, the system cannot accurately determine the scope of the real power outage users and those users who cannot collect information due to communication interruption. This makes it impossible to accurately target users who need emergency repairs after the disaster, greatly affecting the efficiency of power repairs and the speed of power restoration.

[0004] In order to ensure accurate assessment of power outages and timely restoration of power supply in emergency situations such as floods, a highly reliable method for deploying metering devices is needed. At present, the traditional method of deploying metering devices has obvious deficiencies in disaster resistance and cannot effectively deal with the damage caused by floods. How to improve the metering device's ability to resist floods and how to scientifically and cost-effectively deploy metering devices before disasters have become urgent issues to be solved. Summary of the invention

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0027] like Figure 1-7 As shown, a method for deploying a high-reliability metering device before a disaster of the present invention comprises the following steps: S1. Establish a map of power consumption areas. Several metering devices are used to deploy users on the map of power consumption areas. This can provide basic geographic information for subsequent analysis and deployment. Use geographic information system software and field survey data to draw a map of power consumption areas, mark user locations and related infrastructure. Ensure the accuracy and real-time nature of the map, and update and maintain it regularly.

[0028] S2. Establish a GIS three-dimensional terrain map on the power consumption area map, determine the terrain height of the metering device deployment location on the power consumption area map through the GIS three-dimensional terrain map, and establish the terrain height level; the lower the terrain, the higher the waterproof requirement for the metering device, because low-lying areas are more likely to be flooded in disasters such as floods. Collect terrain data and use professional GIS software to build a three-dimensional terrain map. Determine the classification standard of terrain height level and adjust and optimize it according to actual conditions.

[0029] S3. Establish a meteorological database and meteorological grades, and use meteorological grades to assess the potential damage to metering devices; the greater the degree of damage to metering devices caused by weather, the more it is necessary to deploy metering devices with high waterproof grades to cope with the impact of severe weather conditions. Collect meteorological data, including rainfall, wind speed, temperature, etc. Develop an assessment method for meteorological grades, and determine grades based on a combination of different meteorological parameters.

[0030] S4. Establish a historical disaster information database and disaster level, and use the disaster level to determine the degree of damage to the metering devices on the power consumption area map in historical disasters; the greater the degree of damage to the metering devices caused by the disaster, the more it is necessary to deploy metering devices with a high waterproof level to improve the disaster resistance when similar disasters occur again. Organize historical disaster data, including the time, location and impact of disasters such as floods, typhoons and earthquakes. Establish a disaster level assessment system, taking into account factors such as the type, intensity and frequency of disasters.

[0031] S5. Establish a load capacity database and user load capacity levels. In places with large user load capacity, the stability of power supply is required to be higher. Therefore, it is necessary to deploy metering devices with higher waterproof levels to ensure that the power supply of important users is not affected when disasters occur. Collect user load capacity data through power monitoring equipment or user declaration. Divide user load capacity levels and determine the scope and standards of different levels.

[0032] S6. Establish an importance level database and user importance level. The more important the user is, such as hospitals, government agencies, etc., the more waterproof metering devices should be deployed to ensure the power supply of key facilities. Determine the evaluation criteria for user importance, such as user type, social impact, etc. Divide users into important levels to provide a basis for the deployment of metering devices.

[0033] S7. Establish a database of metering devices and waterproof levels of metering devices; metering devices with different waterproof levels have different waterproof capabilities. The better the waterproof capability of the metering device, the higher the cost of use. By reasonably selecting the waterproof level, you can reduce costs while meeting disaster resistance needs. Collect technical parameters and cost information of metering devices with different waterproof levels. Establish a waterproof level system for metering devices to facilitate the selection of appropriate metering devices. S8. Determine the waterproof level of the metering device to be deployed at each location on the power consumption area map by terrain height level, meteorological level, disaster level, user load capacity level and user importance level. Through comprehensive analysis of multiple factors, accurate deployment can be achieved to improve the reliability and disaster resistance of the metering device. Formulate a comprehensive judgment algorithm and calculate according to the weight of each level factor. Determine the waterproof level of the metering device to be deployed at each location on the power consumption area map based on the calculation results.

[0034] Through a multi-step comprehensive analysis, the present invention aims to achieve scientific and reasonable deployment of metering devices in power consumption areas to improve their reliability before disasters. The overall process covers multiple links from establishing basic geographic information to comprehensively judging the waterproof level, and establishes a relatively complete decision-making system.

[0035] Furthermore, in one embodiment, the waterproof levels of the metering device include drip-proof, rain-proof, and immersion-proof types; for the drip-proof metering device, water drops have no harmful effect on it; for the rain-proof metering device, rain has no harmful effect on it; and for the immersion-proof metering device, immersion in water has no harmful effect on it.

[0036] Further, in one embodiment, the terrain height levels include a soaking zone, an intermediate zone, and a safety zone; when a flood disaster occurs, the metering device in the soaking zone is more likely to be submerged and soaked by water; when a flood disaster occurs, the metering device in the intermediate zone is more likely to be located on the upper side and close to the water surface; when a flood disaster occurs, the metering device in the safety zone is more likely to be located on the upper side and farther from the water surface; the soaking zone is numbered 3, the intermediate zone is numbered 2, and the safety zone is numbered 1; when the number of the position where the metering device is deployed on the power consumption area map is 3, an anti-immersion metering device is selected; when the number of the position where the metering device is deployed on the power consumption area map is 2, a rainproof metering device is selected; when the number of the position where the metering device is deployed on the power consumption area map is 1, a drip-proof metering device is selected.

[0037] Furthermore, in one embodiment, the weather level includes general weather, severe weather, and disaster weather; when general weather occurs, the metering device will not be damaged; when severe weather occurs, the metering device is more likely to be slightly damaged; when disaster weather occurs, the metering device is more likely to be seriously damaged; general weather is numbered 1, severe weather is numbered 2, and disaster weather is numbered 3; when the weather number appearing in the power consumption area is judged to be 3, an anti-immersion metering device is selected; when the weather number appearing in the power consumption area is judged to be 2, a rainproof metering device is selected; when the weather number appearing in the power consumption area is judged to be 1, a drip-proof metering device is selected.

[0038] Furthermore, in one embodiment, the disaster levels include general disasters, moderate disasters, and severe disasters; when a general disaster occurs, the metering device will not be damaged; when a moderate disaster occurs, the metering device is more likely to be slightly damaged; when a severe disaster occurs, the metering device is more likely to be seriously damaged; general disasters are numbered 1, moderate disasters are numbered 2, and severe disasters are numbered 3; when the disaster numbered in the power consumption area is judged to be 3, an anti-immersion metering device is selected; when the disaster numbered in the power consumption area is judged to be 2, a rainproof metering device is selected; when the disaster numbered in the power consumption area is judged to be 1, a drip-proof metering device is selected.

[0039] Furthermore, in one embodiment, the user load capacity levels include primary load, secondary load, and tertiary load; primary load is the most important load level, secondary load is a relatively important load level, and tertiary load is a general power load; primary load is numbered 3, secondary load is numbered 2, and tertiary load is numbered 1; when the load level is judged to be numbered 3, an anti-immersion metering device is selected; when the load level is judged to be numbered 2, an anti-rainwater metering device is selected; when the load level is judged to be numbered 1, an anti-drip metering device is selected.

[0040] Furthermore, in one embodiment, the user importance levels include special users, first-level users, and second-level users; the special user is numbered 3, the first-level user is numbered 2, and the second-level user is numbered 1; when it is determined that the user's number is 3, an anti-immersion metering device is selected; when it is determined that the user's number is 2, a rainproof metering device is selected; when it is determined that the user's number is 1, a drip-proof metering device is selected.

[0041] Furthermore, in one embodiment, the terrain height level, meteorological level, disaster level, user load capacity level, and user importance level are all selection constraints; when the selection constraint number is 3, an anti-immersion metering device is selected; when the number of times the selection constraint number 2 appears is greater than the number of times number 1 appears, a rainproof metering device is selected; when the number of times the selection constraint number 1 appears is greater than the number 2, a drip-proof metering device is selected.

[0042] The following describes each step in turn.

[0043] Step S1: Create a power consumption area map Function: It provides a basic geographic framework for the deployment of metering devices, clarifies the location of each user in the electricity consumption area, and provides a spatial reference for subsequent analysis and decision-making.

[0044] Importance: It is the basis of the entire deployment method and ensures the subsequent accurate judgment and analysis of the location of the metering device.

[0045] Step S2: Create GIS 3D terrain map and terrain height level Function: By constructing a three-dimensional topographic map using GIS technology, we can intuitively understand the topography of the power consumption area and then determine the topographic height of the metering device deployment location. Establishing the topographic height level provides a quantitative standard for evaluating waterproofing requirements.

[0046] Importance: Terrain height is one of the important factors affecting the waterproof requirements of metering devices. Low-lying areas are more likely to be flooded during disasters such as floods, so metering devices with higher waterproof levels are required. By establishing terrain height levels, metering devices with different waterproof levels can be deployed in a targeted manner to improve resource utilization efficiency.

[0047] Step S3: Establishing a meteorological database and meteorological levels Function: Collecting meteorological data and establishing meteorological levels can assess the possible damage to metering devices under different meteorological conditions. Meteorological conditions such as rainfall and wind speed have a greater impact on metering devices, and severe weather may cause damage to metering devices.

[0048] Importance: Considering meteorological factors can make the deployment of metering devices more adaptable to different climate environments and improve their disaster resistance under severe meteorological conditions. Deploying metering devices with corresponding waterproof levels according to meteorological levels can effectively reduce the risk of damage to metering devices caused by meteorological disasters.

[0049] Step S4: Establishing a historical disaster information database and disaster levels Function: By collating historical disaster data and establishing disaster levels, we can understand the damage to metering devices in the power consumption area in past disasters. This helps to predict the possible degree of damage to metering devices in different locations when similar disasters occur again.

[0050] Importance: Historical disaster information is valuable experience and lessons. By establishing disaster levels, we can strengthen the deployment of metering devices in disaster-prone areas in a targeted manner based on past disaster situations. Deploying metering devices with higher waterproof levels in these areas can improve the recovery capacity of the power system after a disaster.

[0051] Step S5: Establishing a load capacity database and user load capacity levels Function: The levels are established according to the load capacity of users, reflecting the degree of demand for power supply of different users. Users with large load capacity usually have higher requirements for the stability of power supply.

[0052] Importance: For places with large load capacity, deploying metering devices with high waterproof levels can ensure that the power supply to important users is not affected when a disaster occurs. This helps to ensure the normal operation of key facilities and enterprises and reduce economic losses.

[0053] Step S6: Establishing an importance level database and user importance levels Function: Determine the importance level of users. For example, important users such as hospitals and government agencies need to be given priority in ensuring power supply when a disaster occurs.

[0054] Importance: Deploying metering devices with different waterproof levels according to the importance of the user can ensure the power supply of key facilities during disasters, which is of great significance to social stability and emergency rescue.

[0055] Step S7: Establishing a database of metering devices and waterproof levels Function: To establish a waterproof rating system for metering devices and clarify the waterproof capabilities and usage costs of metering devices with different waterproof ratings. This provides a basis for selecting appropriate metering devices.

[0056] Importance: Considering the cost of metering devices while meeting disaster prevention needs is a key issue in practical applications. By establishing a metering device database, the most cost-effective metering device can be selected according to the needs of different locations to achieve reasonable allocation of resources.

[0057] Step S8: Comprehensively determine the deployment waterproof level Function: Comprehensively consider multiple factors such as terrain height level, meteorological level, disaster level, user load capacity level and user importance level to determine which waterproof level of metering device should be deployed at the location on the electricity consumption area map.

[0058] Importance: This step is the core of the entire technical solution. Through comprehensive analysis of multiple factors, accurate deployment can be achieved, and the reliability and disaster resistance of the metering device can be improved. The limitations of single-factor decision-making are avoided, making the deployment plan more scientific and reasonable.

[0059] The establishment of various databases provides rich data support for deployment decisions. The meteorological database, historical disaster information database, load capacity database and importance level database reflect the characteristics and requirements of the metering device deployment location from different perspectives. These data, combined with the terrain height level and the waterproof level of the metering device, provide a comprehensive decision-making basis for comprehensive judgment.

[0060] By analyzing factors such as topography, weather, disasters, load capacity, and user importance, the risks of different locations can be assessed. According to the risk assessment results, metering devices with different waterproof levels can be reasonably deployed to achieve optimal resource allocation. Metering devices with high waterproof levels can be deployed in high-risk areas, and low-cost metering devices can be selected in low-risk areas, which not only improves disaster resistance but also reduces costs.

[0061] The present invention takes into account a variety of factors and has strong adaptability and flexibility. The terrain, climate, disaster history and user needs of different regions are different. By comprehensively analyzing these factors, a metering device deployment plan suitable for local conditions can be formulated. At the same time, as time goes by and the situation changes, the database can be continuously updated and improved, so that the deployment plan can be adjusted in time to maintain effectiveness. Based on the comprehensive analysis of multiple factors, the scientific deployment of metering devices is achieved, and the disaster resistance and reliability are improved. By accurately deploying metering devices with different waterproof levels, the cost of use is reduced while meeting disaster resistance needs. Relying on a rich database and scientific analysis methods, decisions are made more accurate and reliable. It is suitable for different regions and different disaster situations and has broad application prospects.

[0062] The meteorological database and disaster information database contain historical information, including information about weather and disasters that have occurred in the past. The historical meteorological information in the meteorological database can help assess the risks that metering devices in a specific area may face under different meteorological conditions. For example, if a region has historically experienced frequent heavy rainfall, higher waterproofing requirements need to be considered when deploying metering devices. By analyzing historical meteorological data, the meteorological level of the region can be determined, providing an important basis for selecting the appropriate waterproofing level for metering devices.

[0063] The historical disaster information in the disaster information database is also of great value. It allows us to understand what types of disasters have occurred in a specific area in the past and the extent to which these disasters have affected the metering devices. By analyzing historical disaster information, the disaster level in the area can be determined, and then corresponding protective measures can be taken when deploying metering devices to improve the reliability of metering devices in disasters.

[0064] The waterproof levels of the metering device include drip-proof, rain-proof, and immersion-proof.

[0065] Drip-proof metering devices are not affected by water drops. Drip-proof metering devices are mainly designed for protection against water drops. Under normal use, even if a small amount of water drops, it will not cause any harmful effects on the metering device. It has a certain sealing structure that can prevent water drops from entering the device and protect the internal electronic components and circuits.

[0066] Rainproof metering devices are more protected from rain. They can ensure that rain will not have a harmful effect on the metering device under certain rainfall conditions. They use tighter sealing designs and waterproof materials to prevent rainwater from penetrating. At the same time, drainage designs may also be considered to prevent rainwater from accumulating on the surface of the device.

[0067] Immersion-proof metering devices are immersed in water without any harmful effects. Immersion-proof metering devices have the strongest waterproof ability. Even if immersed in water, it will not cause any harmful effects. The use of special sealing technology and waterproof materials can effectively prevent the ingress of water. At the same time, they may also have pressure resistance to cope with the pressure they may be subjected to in water.

[0068] Metering devices with different waterproof levels have their own characteristics and applicable scenarios. In actual deployment, it is necessary to comprehensively consider factors such as the terrain height, meteorological level, disaster level, user load capacity level and user importance level of the power consumption area to select the appropriate waterproof level metering device to achieve a balance between cost-effectiveness and reliability.

[0069] The terrain height levels include soaking zone, intermediate zone, and safe zone. When a flood occurs, the metering device in the soaking zone is more likely to be submerged and soaked by water. When a flood occurs, the metering device in the intermediate zone is more likely to be located on the upper side and close to the water surface. When a flood occurs, the metering device in the safe zone is more likely to be located on the upper side and far from the water surface. The soaking zone is numbered 3, the intermediate zone is numbered 2, and the safe zone is numbered 1. When the number of the location where the metering device is deployed on the power consumption area map is 3, select an anti-immersion metering device. When the number of the location where the metering device is deployed on the power consumption area map is 2, select a rainproof metering device. When the number of the location where the metering device is deployed on the power consumption area map is 1, select a drip-proof metering device.

[0070] This method of selecting the waterproof level of the metering device according to the terrain height level is highly reasonable. The flooding risks faced by different terrain heights when flood disasters occur are significantly different. The soaking area is more likely to be submerged and soaked in water when a disaster occurs, so it is necessary to select a flood-proof metering device to ensure that it can still work normally in harsh environments. The metering device in the middle area is more likely to be located on the upper side of the water surface and close to the water surface. At this time, the rainproof metering device can better cope with possible splashing and humid environments. At the same time, the cost may be lower than that of the flood-proof type, achieving a better balance between risk and cost. The metering device in the safe area is more likely to be located on the upper side of the water surface and far away from the water surface, and the risk of flooding is the smallest. Choosing a drip-proof metering device can meet basic waterproofing needs and avoid cost waste caused by excessive configuration.

[0071] In this way, metering devices with different waterproof levels can be deployed in a targeted manner according to the actual risk situation in different areas, thereby improving the efficiency of resource utilization and minimizing costs while ensuring the reliability of the metering devices.

[0072] When deploying metering devices in practice, by analyzing the map of the power consumption area and determining the terrain height grade number of each location, the corresponding waterproof grade of the metering device can be quickly selected. This greatly simplifies the decision-making process and improves work efficiency. This method is applicable to various geographical environments and flood risk areas. Whether it is a plain area or a mountainous area, it can be accurately divided according to the terrain height and the appropriate waterproof grade of the metering device can be selected. Metering devices with different waterproof grades also have different maintenance and management. This classified deployment method facilitates the unified management and maintenance of metering devices by the power department. After a disaster occurs, targeted repairs and replacements can be carried out according to the characteristics of different areas, which speeds up the restoration of power supply.

[0073] In actual applications, it may be difficult to accurately determine the terrain height level of each location on the power consumption area map. Factors such as terrain complexity and measurement errors may affect the accuracy of the judgment. Solution: A variety of measurement methods and technical means, such as topographic measurement instruments and satellite image analysis, can be used to improve the accuracy of terrain height level judgment. At the same time, combined with historical flood disaster data and field surveys, the judgment results can be verified and adjusted.

[0074] The weather levels include general weather, severe weather, and disaster weather. When general weather occurs, the metering device will not be damaged. When severe weather occurs, the metering device is more likely to be slightly damaged. When disaster weather occurs, the metering device is more likely to be seriously damaged. General weather is numbered 1, severe weather is numbered 2, and disaster weather is numbered 3. When the weather number in the power consumption area is judged to be 3, select an anti-immersion metering device. When the weather number in the power consumption area is judged to be 2, select a rainproof metering device. When the weather number in the power consumption area is judged to be 1, select a drip-proof metering device.

[0075] Different weather levels represent the impact of different degrees of meteorological risks on metering devices. When disastrous weather occurs, it is numbered 3. At this time, it is reasonable to choose an anti-immersion metering device, because the metering device is likely to be seriously damaged under disastrous weather, and the anti-immersion metering device can ensure normal operation in harsh flooding environments and effectively respond to possible flooding and other situations. Severe weather is numbered 2, and the metering device is likely to be slightly damaged. Choosing a rainproof metering device can better resist the invasion of wind and rain and prevent rainwater from penetrating and damaging the device. General weather is numbered 1, and the metering device will not be damaged. Choosing a drip-proof metering device can meet basic waterproofing needs without causing excessive cost investment.

[0076] Choosing metering devices with different waterproof levels according to the meteorological level can achieve a balance between cost and benefit while ensuring the reliability of the metering devices. For areas with lower meteorological risks, choosing metering devices with lower waterproof levels can reduce costs; while for areas with higher meteorological risks, choosing metering devices with higher waterproof levels can improve disaster resistance and reduce equipment damage and maintenance costs caused by meteorological disasters.

[0077] Disaster levels include general disasters, moderate disasters, and severe disasters. In the event of a general disaster, the metering device will not be damaged. In the event of a moderate disaster, the metering device may be slightly damaged. In the event of a severe disaster, the metering device may be seriously damaged. General disasters are numbered 1, moderate disasters are numbered 2, and severe disasters are numbered 3. When the number of the disaster in the power consumption area is judged to be 3, select an anti-flood metering device. When the number of the disaster in the power consumption area is judged to be 2, select a rainproof metering device. When the number of the disaster in the power consumption area is judged to be 1, select a drip-proof metering device.

[0078] Different disaster levels mean different possibilities of damage to the metering device. In the case of a severe disaster (numbered 3), the metering device is more likely to be severely damaged. At this time, choosing an anti-immersion metering device can protect the equipment to the greatest extent and ensure that it can still operate normally in a harsh disaster environment. This device can effectively resist extreme situations such as flooding. In the case of a moderate disaster (numbered 2), the metering device is more likely to be slightly damaged. The rainproof metering device can cope with a certain degree of water intrusion and humid environment, which not only meets the protection needs, but also avoids the cost increase caused by excessive configuration of high-level waterproof devices. In general disasters (numbered 1), the metering device will not be damaged. Choosing a drip-proof metering device is sufficient to meet basic waterproof requirements while reducing costs.

[0079] Selecting the waterproof level of metering devices according to the disaster level can make resources more reasonably allocated. High-level waterproof devices are configured in areas with high disaster risks to ensure the stable operation of key facilities; while low-level waterproof devices are selected in areas with low disaster risks to avoid unnecessary waste of resources.

[0080] When deploying metering devices, the waterproof level of the metering device to be selected can be quickly determined by judging the disaster level number of the power consumption area. This greatly simplifies the decision-making process, improves work efficiency, and enables power departments to plan and deploy more quickly.

[0081] This method is applicable to different types of disaster scenarios. Whether it is floods, typhoons or earthquakes, the appropriate waterproof level of the metering device can be selected according to the disaster level. This enables the metering device to better adapt to various complex disaster environments and improves the disaster resistance of the power system.

[0082] The user load capacity levels include primary load, secondary load, and tertiary load. Primary load is the most important load level, secondary load is a relatively important load level, and tertiary load is a general power load. The primary load is numbered 3, the secondary load is numbered 2, and the tertiary load is numbered 1. When the load level is judged to be numbered 3, select an anti-immersion metering device. When the load level is judged to be numbered 2, select a rainproof metering device. When the load level is judged to be numbered 1, select a drip-proof metering device.

[0083] The user load capacity level reflects the importance of different loads to the power supply. The primary load is usually the most important, such as key facilities such as hospitals and emergency command centers, and power outages may cause serious consequences. In this case, choosing an anti-immersion metering device can ensure that the metering device can work normally even in harsh environments, such as floods, thereby providing accurate power metering and stable power supply guarantees for the primary load. The secondary load is more important, such as some large enterprises, commercial centers, etc. Choosing a rainproof metering device can resist possible rain intrusion and humid environment to a certain extent, and meet the reliability requirements of the secondary load for power metering. The tertiary load is generally an ordinary power load, such as residential electricity. The drip-proof metering device is sufficient to meet its basic waterproof needs, while avoiding the cost waste caused by over-configuration of high-level waterproof devices.

[0084] Selecting metering devices with different waterproof levels according to the user's load capacity level can achieve cost-effectiveness optimization while ensuring the reliability of the power system. For important loads, it is reasonable to invest higher costs to select metering devices with high waterproof levels; while for general loads, selecting metering devices with low waterproof levels can reduce costs and improve resource utilization efficiency.

[0085] In the actual planning and deployment of power systems, the waterproof level of metering devices can be determined by the user's load capacity level, which can clarify the key protection objects. Priority is given to configuring metering devices with high waterproof levels for important loads to ensure the stable power supply of key facilities under various circumstances and improve the overall reliability of the power system. This method provides a clear decision-making basis for the power sector. After determining the user's load capacity level, the corresponding waterproof level of the metering device can be quickly selected, which simplifies the decision-making process and improves work efficiency.

[0086] The user importance levels include special users, first-level users, and second-level users. The special user number is 3, the first-level user number is 2, and the second-level user number is 1. When the user number is judged to be 3, select the anti-immersion type metering device. When the user number is judged to be 2, select the rainproof type metering device. When the user number is judged to be 1, select the drip-proof type metering device.

[0087] The classification of user importance levels helps to determine the criticality of different users in the power system. Special users are usually units with extremely high importance, such as key national security departments, emergency centers of large medical institutions, etc. These users need to ensure stable and reliable power supply under any circumstances. Therefore, the selection of anti-immersion metering devices can protect metering equipment in the worst disaster environment, ensure accurate metering and power monitoring, and provide strong guarantee for the continuous power supply of special users. First-level users may be some important enterprises, public service agencies, etc., which have high requirements for the reliability of power supply. Rainproof metering devices can resist the impact of common bad weather and minor disasters to a certain extent, meet the power metering needs of first-level users, and ensure the normal operation of the power system in most cases. Second-level users are generally ordinary users, and their importance to power supply is relatively low. Drip-proof metering devices are sufficient to meet their daily waterproof needs while avoiding unnecessary cost investment.

[0088] Selecting the waterproof level of metering devices according to the importance of users can achieve a reasonable allocation of risks and resources. For important users, more resources are invested in selecting metering devices with high waterproof levels to reduce the risk of power supply interruption due to disasters and other reasons; for ordinary users, a lower-cost waterproof level is adopted to improve resource utilization efficiency while meeting basic needs.

[0089] In actual power system management, by clarifying the importance level of users and selecting the corresponding waterproof level of metering devices, the key points of protection can be highlighted. Priority is given to configuring high-reliability metering devices for special-grade users and first-grade users to ensure that the power supply situation can be quickly and accurately grasped in an emergency, and timely response measures can be taken to improve the emergency response capability of the power system. This method provides a clear management framework for the power sector. When deploying and maintaining metering devices, classified management can be carried out according to the importance level of users, and maintenance plans and emergency plans can be formulated in a targeted manner to improve management efficiency and service quality.

[0090] The terrain height level, meteorological level, disaster level, user load capacity level, and user importance level are all selection constraints. When the selection constraint number is 3, select the anti-immersion metering device. When the number of selection constraints 2 is greater than the number of number 1, select the rainproof metering device. When the number of selection constraints 1 is greater than the number of number 2, select the drip-proof metering device. Considering multiple factors such as terrain height level, meteorological level, disaster level, user load capacity level, and user importance level as selection constraints can comprehensively evaluate the risks faced by the metering device from different angles. For example, in the case of low terrain height, bad weather, in a severe disaster area, high load capacity or important users, the metering device is more likely to be affected by disasters such as floods. By combining these factors, the appropriate waterproof level can be determined more accurately, and the reliability of the metering device in various complex situations can be improved. Different selection constraints reflect potential risks in different aspects, and a single factor may not fully reflect the actual situation. Comprehensive consideration of multiple factors can avoid improper selection of waterproof levels due to one-sided judgment and better adapt to the needs of different scenarios.

[0091] In actual applications, different regions may face different terrain, weather, disasters, etc., and the load capacity and importance of users are also different. This comprehensive consideration method can adapt to complex and changing environments and provide personalized metering device waterproof level selection solutions for different regions and users. Whether it is a low-lying area susceptible to floods, an area with complex meteorological conditions, or an important user with special requirements for power supply, the most suitable waterproof level can be determined by comprehensively analyzing multiple selection constraints to improve the overall stability and disaster resistance of the power system.

[0092] When any selection constraint is numbered 3, it means that the risk corresponding to the factor is extremely high. For example, the terrain is in a flooding area, there is a disaster weather or severe disaster, the user is a first-class load or a special user, etc. In this case, choosing an anti-flooding metering device can ensure that the metering device can still work normally under the worst conditions and effectively protect the equipment from severe disasters such as flooding. This rule reflects the focus on protection of high-risk situations, ensuring the reliability of metering devices in extreme situations, and providing protection for the power supply of key facilities and important users.

[0093] When the number of times number 2 appears in the selection constraint is greater than the number of times number 1 appears, it indicates that the overall risk is at a medium level. Taking multiple factors into consideration, although it has not reached the highest risk level, there is still a certain risk of flooding and disasters. Rainproof metering devices can resist rainwater invasion and the impact of minor disasters to a certain extent, meeting the waterproofing needs in this case. This rule takes into account the combined impact of multiple factors. By comparing the number of occurrences of number 2 and number 1, it can more accurately judge the overall risk level and select the appropriate waterproofing level. It not only avoids the cost increase caused by excessive protection, but also improves the disaster resistance of the metering device to a certain extent.

[0094] When the number 1 appears more than the number 2 in the selection constraint, the overall risk is low. Taking all factors into consideration, the metering device faces a low risk of flooding and disasters. Drip-proof metering devices are sufficient to meet basic waterproofing needs while reducing costs. This rule optimizes costs while ensuring the basic waterproofing function of the metering device. For situations with lower risks, choosing a low-level waterproof device can improve resource utilization efficiency and avoid unnecessary investment.

[0095] Comprehensive judgment of multiple selection constraints can improve the accuracy of waterproof level selection and reduce the risk caused by inaccurate judgment of a single factor. Personalized solution: According to the specific conditions of different regions and users, personalized selection solutions for waterproof level of metering devices can be formulated to better meet actual needs. Strong adaptability: Adapt to various complex environments and changes in situations, adjust the waterproof level in time with the changes of different factors, and improve the flexibility and disaster resistance of the power system.
