Technical Field

[0002] To ensure the stable operation of the power grid, substation equipment needs to be inspected. Currently, the main mode of substation inspection relies on manual operation to formulate fixed-cycle inspection plans in the production management system. After the fixed-cycle inspection plan is formulated, intelligent devices such as drones, robots, cameras, and IoT sensors can be used to collect inspection data.

[0003] This inspection model suffers from several drawbacks. The limited availability of data for decision-making makes it difficult to promptly inspect equipment with potential hazards or malfunctions.

A first score is determined for each dimension of the multi-dimensional data according to its respective scoring algorithm. An inspection score for the substation is determined based on the first score and a preset scoring model. Based on the inspection score, the inspection level and inspection plan are determined. Therefore, the determination of the substation inspection plan is no longer based on a single control level dimension, but on an inspection score determined by multi-dimensional data including control level, operating years, load, faults, inspection plan, and environmental data. The determined inspection level dynamically changes with changes in different dimensions of data, improving the flexibility of dynamic adjustment of the inspection plan and increasing its accuracy. Furthermore, displaying the inspection levels and inspection plans of different substations on a GIS map enhances the visualization capability of substation operation and maintenance information for users.

[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] Currently, the inspection of power grid substation equipment is based on the equipment's critical speed and health status, and the periodic inspection plan is formulated manually.

[0043] Figure 1 For example, a schematic diagram of an application scenario. Figure 1 As shown, multiple substations can be configured in the power grid, such as substations 1011 and 1012. Each substation can be equipped with multiple electrical devices, such as electrical device 1, electrical device 2, ... and electrical device N in the figure, where N is any integer greater than 2. The control level 102 of each electrical device can be obtained from the operation and maintenance system, and user 103 can determine the periodic inspection plan for each electrical device based on the control level 102 of different electrical devices.

[0044] As the power grid expands and equipment becomes more complex, the aforementioned inspection plan formulation model suffers from the following problems:

[0045] First, the inspection plan is mainly based on a single indicator of equipment control level (determined by both equipment importance and health status), without fully considering the coupled impact of multi-dimensional data such as equipment load, fault status, and environmental factors. Because the inspection plan needs to be executed, it is impossible to inspect equipment with potential hazards or faults in a timely manner.

[0046] Secondly, the fixed-cycle inspection lacks dynamic adjustment capabilities and cannot respond in real time to abnormal situations such as sudden load changes and temperature changes. Therefore, it may fail to detect equipment abnormalities in a timely manner, increasing the risk of failure.

[0047] Third, the inability to view complete information on a single interface affects the efficiency of assessing overall risks.

[0048] The solution provided in this application no longer relies on a single control level data when determining the inspection plan for substation equipment. Instead, it uses multi-dimensional data, including control level, service life, load, faults, inspection plan, and environmental data, to determine the inspection score. This allows the determined inspection level to dynamically change with variations in different data dimensions, improving the flexibility and accuracy of the inspection plan. Furthermore, displaying the inspection levels of different substations on a GIS map enhances the visualization of substation operation and maintenance information for users.

[0049] Please refer to Figure 2 , Figure 2 A flowchart illustrating the GIS map-based substation equipment operation and maintenance method provided in this application embodiment. Figure 1 ,like Figure 2 As shown, the method includes the following steps:

[0050] S201: In response to the highest data update frequency of the power equipment, acquire multi-dimensional data of the power equipment, including control level, years of operation, load, faults, inspection plan and environmental data; the acquisition frequency of each multi-dimensional data is different.

[0051] In this embodiment, the execution entity of the substation equipment operation and maintenance method based on GIS maps can be any electronic device that manages the operation and maintenance of multiple substations. This electronic device can communicate with the production management system, the Supervisory Control and Data Acquisition (SCADA) system, and the environmental data system. It can collect control level, service life, load, and fault data from the production management system according to its respective frequency; it can also obtain inspection plan data for each device from the production management system. The execution entity can obtain environmental data related to different devices from the environmental data system. Environmental data includes temperature and humidity, etc.

[0052] The aforementioned executing entities can store the acquired data in a pre-defined database. It is understandable that the collection frequency differs for data of different dimensions. For example, the collection frequency for equipment operating years and management level is low, such as once per month. The collection frequency for equipment fault records and maintenance plans is medium, such as once per week. The collection frequency for equipment load and environmental data is high, such as once per hour.

[0053] For each dimension of data, the aforementioned executing entity can collect data for that dimension from multiple power equipment in different substations according to the collection frequency for that dimension, and store the data for that dimension for each power equipment.

[0054] To address the time alignment issue, this application employs a time window-based synchronization strategy, aligning data according to the smallest time window unit (the period corresponding to the highest acquisition frequency). The following explanation uses a single transformer as an example. For a single transformer, when data for one or more dimensions of the device is acquired at the highest acquisition frequency, parameters acquired at lower frequencies and the latest parameters (most recently acquired at intermediate frequencies) can be added to the multidimensional data acquired at the highest frequency, resulting in a complete set of multidimensional data for the device.

[0055] Schematic representation: At time T1, the load AL and ambient temperature AT of substation A are collected from SCADA and the environmental system at a frequency of once per hour. If the equipment's operating age and control level, fault records, and maintenance plans have not been collected at this time, the load AL and ambient temperature AT can be supplemented by the most recently collected equipment operating age AY and control level AC, fault records AD, and maintenance plans AP, resulting in a single multidimensional data point for substation A at time T1. This multidimensional data point is shown in Table 1 below:

[0056] Table 1

[0057]

[0058] It is understandable that the aforementioned executing entity can obtain multi-dimensional data of multiple power substations in the manner described above each time it detects a data update at the highest acquisition frequency.

[0059] S202: For each dimension of data, determine the first score of that dimension of data according to the scoring algorithm corresponding to that dimension of data; determine the inspection score of the substation equipment according to the preset scoring model and the first scores of each of the multi-dimensional data.

[0060] You can set separate scoring algorithms for different dimensions of data. For each dimension of data, calculate the first score for that dimension based on the corresponding scoring algorithm.

[0061] In some implementations, the scoring algorithm corresponding to the control level is related to the control level of the power equipment;

[0062] The scoring algorithm corresponding to the service life is related to the ratio of the service life of the power equipment to its service life.

[0063] The scoring algorithm corresponding to the load is related to the ratio of the current load to the rated load of the power equipment;

[0064] The fault scoring algorithm is related to the sum of the ratios of the level of each fault to the highest fault level in the history of multiple faults of the power equipment.

[0065] The scoring algorithm corresponding to the inspection plan is related to the length of the time interval between the current moment and the most recent maintenance of the substation equipment.

[0066] The scoring algorithm corresponding to ambient temperature is related to the range of ambient temperature.

[0067] To illustrate, the scoring algorithm for the control level of power equipment is as follows: .

[0068] To illustrate, the algorithm for scoring the service life of power equipment is as follows:

[0069] .

[0070] In other words, the scoring algorithm for the service life of power equipment takes the minimum value between 100 and (service life of equipment) × 100. The service life of the equipment (i.e., the power equipment) can be the number of years the power equipment has been used from the time it was put into use until the statistical time. The service life of the equipment can be the service life recommended at the time of manufacture, or it can be the average service life of similar power equipment.

[0071] Schematic representation: The load scoring algorithm for power equipment is as follows: .

[0072] The current load can be, for example, the load current of the power equipment; correspondingly, the rated load can be the rated operating current of the power equipment. Furthermore, the current load can also be the current output power of the power equipment. The rated load can be the rated output power of the power equipment.

[0073] The fault scoring algorithm for power equipment is as follows: .

[0074] Where n represents the number of historical faults of the power equipment. Let L be the severity level of the i-th fault (20 for other faults, 50 for general faults, 80 for major faults, and 100 for emergency faults), and max(L) be the highest fault level of the equipment.

[0075] The scoring algorithm for power equipment maintenance plans is as follows:

[0076] ;

[0077] Among them, the power equipment is included in the latest maintenance plan.

[0078] The ambient temperature scoring algorithm is as follows: Where T is the ambient temperature.

[0079] For each power equipment, the first score corresponding to each dimension can be determined by using the latest multidimensional data of the power equipment and the data of each dimension in the multidimensional data.

[0080] This method allows us to obtain the first score corresponding to each dimension of the data.

[0081] In these implementations, by setting separate scoring algorithms for different dimensions, the scoring algorithm for each dimension is more closely aligned with the data features of that dimension. By using the squared algorithms for each dimension's data, the accuracy of the first score for each dimension can be improved, thereby making the inspection score determined based on the first score for each dimension more accurate, which in turn helps to improve the effectiveness of the determined inspection plan.

[0082] For each power equipment, after obtaining the first score corresponding to each dimension of data, the inspection score of the power equipment can be determined using a preset scoring model and the data of each dimension.

[0083] Schematic, the preset scoring model for power equipment is represented by the following formula (1):

[0084] (1); where,

[0085] S imp The first score for the control level of power equipment; S age The first score for the service life of the power equipment; S load The first component of the load on the transformer equipment; S def The first score for power equipment faults; S plan The first score for the substation equipment maintenance plan; S env The first score is the ambient temperature of the substation. The weighting coefficients corresponding to the control levels. The weighting coefficients corresponding to the years of operation. The weighting coefficients corresponding to the load of the power equipment; The weighting coefficients corresponding to power equipment faults. The weighting coefficients corresponding to the maintenance plan for power equipment; This is the weighting coefficient corresponding to the ambient temperature of the power equipment.

[0086] The weighting coefficients corresponding to the different dimensions of data mentioned above can be determined based on the historical significance of the different dimensions of data, or they can be preset by the user.

[0087] S203: Determine the inspection level of the substation equipment and the corresponding inspection plan based on the inspection score.

[0088] In some implementations, for each piece of equipment in at least one substation, the inspection level of the equipment is determined based on the inspection score of the equipment and a preset mapping relationship; wherein, the mapping relationship represents the mapping between different inspection scores and different inspection levels; each inspection level corresponds to a preset inspection plan.

[0089] In one example, the above mapping relationship could be as follows: different inspection score ranges correspond to different inspection levels, and each inspection level can be preset with a corresponding inspection plan.

[0090] Different inspection score ranges correspond to different inspection levels. For example, when the inspection score is greater than or equal to the first preset score, the inspection level is the highest; when the inspection score is less than the first preset score but greater than or equal to the second preset score, the inspection level is the second highest; when the inspection score is less than the second preset score but greater than or equal to the third preset score, the inspection level is the medium; and when the inspection score is less than the third preset score, the inspection level is the lowest. The first preset score could be, for example, 80 points, the second preset score could be, for example, 70 points, and the third preset score could be, for example, 60 points, etc. These first, second, and third preset scores can be set according to specific application scenarios and are not limited here.

[0091] Inspection plans for different inspection levels can be as follows: the highest inspection level corresponds to 1 inspection per day; the second highest inspection level corresponds to 1 inspection per week; the medium inspection priority corresponds to 2 inspections per month; and the low priority corresponds to 1 inspection per month.

[0092] In these implementations, the inspection level of power equipment can be quickly determined through the above mapping relationship.

[0093] S204: Synchronize the inspection level and inspection plan corresponding to the power equipment of at least one substation to the GIS map so as to display the inspection level and / or inspection plan of each substation in the GIS map.

[0094] In one example, the aforementioned execution entity can run and display a Geographic Information System (GIS) map. In this example, after synchronizing the inspection level and inspection plan of at least one substation to the GIS map, the inspection level of each substation can be displayed on the map.

[0095] In one example, the aforementioned implementing entity can synchronize the inspection levels and inspection plans of different substation equipment to other electronic devices running GIS maps, so that the inspection levels of each substation can be displayed on the other electronic devices.

[0096] GIS maps can display information related to geographical location. In this application, substation identifiers can be displayed at the geographical locations of different substations on the GIS map, and corresponding inspection level identifiers can be displayed near each substation identifier.

[0097] In some examples, an inspection level identifier can be displayed near each substation identifier in the GIS map. This inspection level identifier can be the highest inspection level identifier among the multiple power equipment in the substation indicated by the substation identifier.

[0098] For example, substation B includes multiple electrical equipment B1, B2 and B3. The inspection levels corresponding to the above electrical equipment B1, B2 and B3 are respectively the highest inspection level, medium inspection level and lowest inspection level. The highest inspection level can be displayed near the substation sign of substation B.

[0099] In some examples, the inspection level identifiers for each piece of equipment in a substation can be displayed near the substation identifier on the GIS map.

[0100] In this embodiment, multi-dimensional data of the substation is acquired when the data corresponding to the highest acquisition frequency is updated. A first score is determined for each dimension of the multi-dimensional data using its respective scoring algorithm. Based on the first score and a preset scoring model, the inspection score of the substation is determined. The inspection level and inspection plan are then determined based on the inspection score. Therefore, the determination of the substation inspection plan is no longer based on a single control level dimension, but rather on an inspection score determined by multi-dimensional data including control level, years of operation, load, faults, inspection plan, and environmental data. This allows the determined inspection level to dynamically change with different dimensional parameters, improving the flexibility of dynamic adjustment of the inspection plan and increasing its accuracy. Furthermore, the inspection levels and plans of different substations are displayed on a GIS map, enabling users to see these information on a GIS map and improving the visualization capabilities of substation operation and maintenance information.

[0101] In some optional implementations of this embodiment, the method further includes the following steps:

[0102] In response to receiving the user's filtering operation for the target inspection level, information on multiple substations belonging to the target inspection level is displayed on the GIS map, wherein multiple substations belonging to the target inspection level belong to at least one substation.

[0103] In these optional implementations, the GIS map can display different inspection level filters. Users can select a target inspection level filter from these filters and trigger an operation on that target inspection level filter. The user's triggering of the target inspection level filter will display the identifiers of multiple substation devices corresponding to the target inspection level on the GIS map. These multiple substation devices can be distributed across different substations. The target inspection level can be, for example, any one of the following: highest inspection level, second highest inspection level, medium inspection level, and lowest inspection level.

[0104] In one example, the identifiers of multiple substation devices corresponding to the target inspection level can be displayed as a list. In another example, the identifiers of multiple substation devices matching the target inspection level can be displayed on a GIS map, while the identifiers of substation devices corresponding to other inspection levels are hidden.

[0105] Among these optional implementation methods, by filtering the target inspection level by the user, the power equipment of multiple substations that match the target inspection level can be uniformly presented to the user on the GIS map, thereby further improving the visualization of power equipment operation and maintenance information.

[0106] Please refer to Figure 3 , Figure 3 A flowchart illustrating the GIS map-based substation equipment operation and maintenance method provided in this application embodiment. Figure 2 ,like Figure 3 As shown, this development includes, in addition to, with Figure 2 In addition to steps S301 to S304 related to S201 to S204 in the illustrated embodiment, the method includes the following steps:

[0107] S305: Synchronize the load data of each power equipment to the GIS map.

[0108] S306: In response to a load heatmap display command executed in a GIS map, display a load layer; wherein the load layer displays load heatmaps of multiple power equipment belonging to different substations.

[0109] The entity executing the GIS map-based substation equipment operation and maintenance method (such as electronic equipment that performs operation and maintenance management of substation equipment in multiple substations) can synchronize the load data of the substation equipment in multiple substations to the GIS map.

[0110] GIS maps can also include load heat maps, which by default need to be displayed according to the user's display instructions.

[0111] Users can issue load heatmap display commands in the GIS map to display load layers. A load layer can display load heatmaps for multiple power distribution devices. The load heatmap can display color-coded maps corresponding to the load of each device. For example, high load (≥80% of rated load) is marked with a red heatmap area, medium load (50%~80% of rated load) with an orange heatmap area, and low load (≤50% of rated load) with a green heatmap area.

[0112] In some implementations, the method further includes:

[0113] In response to a user's triggering operation on the load information of the target substation in the load heatmap, the load details and load change trend graph of the target substation are displayed.

[0114] In these implementations, in the load heatmap, the user can trigger an operation on the load color map corresponding to the target device, which can display the load details and load change trend map of the target device.

[0115] Load details include equipment identification, load current, load voltage, and load power.

[0116] Load change trend charts can be generated from equipment load data acquired at multiple time points. These charts can be used to identify equipment experiencing sudden load changes.

[0117] Presenting load details and load change trend graphs for the target substation equipment helps identify equipment with abnormal loads.

[0118] In this embodiment, by displaying a load heat map in a GIS map, users can browse the load heat maps of multiple power equipment in the GIS map, thereby further improving the visualization of power equipment operation and maintenance and helping to improve the efficiency of power equipment operation and maintenance.

[0119] Please refer to Figure 4 , Figure 4 A flowchart illustrating the GIS map-based substation equipment operation and maintenance method provided in this application embodiment. Figure 3 ,like Figure 4 As shown, this development includes, in addition to, with Figure 2 In addition to steps S401 to S404 related to S201 to S204 in the illustrated embodiment, the method includes the following steps:

[0120] S405: Synchronize the fault data of each power equipment to the GIS map.

[0121] S406: In response to a fault map display command executed in a GIS map, display a fault layer; the fault layer displays fault information of power equipment in different substations, including fault level information.

[0122] To illustrate, the identifier of each power equipment can be associated with the substation it belongs to, and each substation can have a location attribute. Through the aforementioned location attribute, the substation can be associated with a GIS map.

[0123] The entity executing the GIS map-based substation equipment operation and maintenance method (such as electronic equipment that performs operation and maintenance management of substation equipment in multiple substations) can synchronize the fault data of substation equipment in multiple substations to the GIS map.

[0124] When a device malfunctions, its fault data can be added to the GIS map. This data includes the fault type, fault level, and time of occurrence. Each device's fault data is associated with its identifier. The fault level can refer to the severity of the fault.

[0125] The fault map can be a distribution map of faulty equipment. Users can execute a command to display the faulty equipment distribution map in a GIS map. Upon receiving the command, the executing entity obtains fault information of all substation equipment that occurred within a preset time period from the time the command was received. A faulty equipment distribution map is then generated based on the fault information of all substation equipment.

[0126] The above fault equipment distribution map can also display the fault level of the substation equipment using different colors: Emergency Fault (red), Major Fault (orange), General Fault (yellow), and Other Fault (blue).

[0127] By displaying fault information for multiple substation devices on a fault layer, users can browse the fault status of all substation devices from a GIS map, improving the efficiency of obtaining information about faulty substation devices. This is beneficial for improving the operation and maintenance efficiency of substation equipment.

[0128] In some implementations, the method further includes:

[0129] In response to the command to view fault details of the target substation in the fault layer, display the fault detail data of the target substation.

[0130] The target substation can be at least one of a plurality of substations.

[0131] In these implementations, users can trigger operations on target substation equipment within the fault layer.
