[0002] With the development of digital technologies, Internet technologies have also been widely applied in the power grid field. Currently, full coverage of the automatic meter reading function has been achieved in some power grids. In this case, power grid employees no longer need to perform periodic on-site meter readings, greatly reducing the workload of power grid employees. However, there are still parts that need to be digitized in other areas of the power grid. Currently, low-voltage users are widely distributed, and their electricity consumption addresses are often very specific and difficult to find in existing maps. Moreover, as the old employees familiar with low-voltage electricity consumption situations retire one after another, and there is no relevant positioning and topology data for low-voltage distribution in the Geographic Information System (GIS), it is difficult to quickly find users or meters, resulting in difficulty in locating the distribution of low-voltage substation area users and increasing the difficulty of metering operation and maintenance and customer service. In addition, the routing of low-voltage power grid distribution lines lacks the support of actual data, and low-voltage distribution network planning mainly relies on impressions, making it difficult to accurately solve problems. In addition, due to the intricate distribution of low-voltage conductors in the substation area, the difficulty of generating the topology of the low-voltage substation area is high. The existing generation of the low-voltage substation area topology is mainly achieved manually, and the accuracy of the low-voltage substation area topology map is poor, and it cannot be updated along with other digital systems, resulting in difficulty in maintaining the low-voltage substation area topology map.

[0039] Embodiment 1

[0040] Figure 1 It is a flowchart of a low-voltage substation area topology generation method provided according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of automatic generation of low-voltage substation area topology. This method can be executed by a low-voltage substation area topology device, and the low-voltage substation area topology device can be implemented in the form of hardware and / or software. As Figure 1 shown, the method includes:

[0041] Step 110, obtain the device data of the electrical devices in each low-voltage substation area.

[0042] Among them, a low-voltage power distribution area can be the area powered by the low-voltage side of a certain transformer. The accurate division of the low-voltage power distribution area is convenient for maintenance personnel to carry out equipment maintenance, power consumption calculation, line loss statistics, etc. Electrical equipment can be equipment that consumes electrical energy within each low-voltage power distribution area, and can be a power-receiving device that obtains power from a power supply device through a network, and can include equipment such as distribution transformer monitoring and metering terminals, concentrators, single-phase meters, three-phase meters, and T-joints. Equipment data can be power-related attribute information corresponding to each user equipment, and the equipment data can include information such as the user number, user name, affiliated power distribution area, power supply unit, location, wire diameter, etc. of the electrical equipment.

[0043] In an embodiment of the present invention, equipment data of electrical equipment can be collected within different low-voltage power distribution areas, and the collection process can include extracting equipment data of electrical equipment from existing digital information and collecting equipment data of electrical equipment on-site.

[0044] Step 120: Determine the topology metadata corresponding to each electrical equipment according to the data collection model and the equipment data.

[0045] Among them, the data collection model can be a model for organizing equipment data. The data collection model can include rules for organizing data and types of equipment data, etc. For example, the data collection model can include rules for extracting the electrical equipment identifier or user name in the equipment data. The data collection model can include one or more rules for organizing equipment data, and the rules for organizing equipment data in the data collection model can be dynamically updated according to user requirements. Topology metadata can be the constituent elements of a topology. Each topology metadata can correspond to a user equipment, and the information in the topology metadata can be organized through the data collection model.

[0046] In an embodiment of the present invention, a pre-configured data collection model can be extracted, and the equipment data of each collected electrical equipment can be organized according to the data collection model, so as to generate topology metadata corresponding to each electrical equipment. It can be understood that the topology metadata can be configured based on the use of the low-voltage power distribution area topology. For example, when conducting line loss statistics based on the low-voltage power distribution area topology, the topology metadata can include the distance from the electrical equipment to the transformer or the distance from the electrical equipment to the previous electrical equipment, etc.

[0047] Step 130: Organize the topology metadata into a low-voltage power distribution area topology according to the power consumption sequence of each electrical equipment to the corresponding low-voltage power distribution area.

[0048] Among them, the power consumption sequence can be the distance from the electrical equipment to the power supply end of the low-voltage power distribution area. For example, if an electrical equipment is connected to the transformer of the low-voltage power distribution area through several other electrical equipment, the number of other electrical equipment passed through can be used as the power consumption sequence of the electrical equipment.

[0049] Specifically, after obtaining the topological metadata corresponding to each electrical equipment, for each low-voltage substation area, the sequence relationship of the corresponding topological metadata can be established by connecting them in sequence according to the power consumption order of the electrical equipment in the low-voltage substation area where it is located, so as to connect the topological metadata of different electrical equipment within the scope of each low-voltage substation area into a low-voltage substation area topology.

[0050] In the embodiment of the present invention, by collecting the equipment data of different electrical equipment in the low-voltage substation area, sorting the equipment data according to the data collection model to generate the topological metadata corresponding to each electrical equipment, and connecting the corresponding topological metadata into a low-voltage substation area topology according to the power consumption order of the electrical equipment in each low-voltage substation area. The embodiment of the present invention realizes the automatic generation of the low-voltage substation area topology, which is convenient for visual display of equipment data based on the low-voltage substation area, helps the operation and maintenance personnel to perform operation and maintenance on the electrical equipment and lines within the scope of the substation area, can reduce the time and difficulty for users to find the equipment location, and the data in the generated digital low-voltage substation area topology is convenient to update, which is convenient for the update and maintenance of the low-voltage substation area topology in the subsequent use process.

[0051] Embodiment 2

[0052] Figure 2 is a flowchart of a method for generating a low-voltage substation area topology according to Embodiment 2 of the present invention. The embodiment of the present invention is a specific implementation based on the above-mentioned embodiment of the invention. Refer to Figure 2 , the method provided by the embodiment of the present invention specifically includes the following steps:

[0053] Step 210: Search for the equipment data of the electrical equipment associated with each low-voltage substation area in the digital power grid system.

[0054] Among them, the digital power grid system can be an existing power grid system, and the number of digital power grid systems can be one or more.

[0055] In the embodiment of the present invention, by docking with the existing digital power grid system, the equipment data of the electrical equipment in each low-voltage substation area can be collected in the digital system. It can be understood that the equipment data collected in the digital power grid system can generate all or part of the data of the topological metadata.

[0056] Step 220: Receive the equipment data of the electrical equipment in each low-voltage substation area collected on site.

[0057] Specifically, the user can also collect the equipment data of the electrical equipment in different low-voltage substation areas on site, and upload the equipment data collected on site through the user terminal. The device executing the method of the embodiment of the present invention can receive the equipment data uploaded by the user.

[0058] Step 230: Extract the data collection rules configured in the data collection model.

[0059] Among them, the data collection rule can be a rule for processing device data. The device data can be organized into topological metadata using the data collection rule. It can be understood that one or more data collection rules can be configured in the data collection model, and the user can adjust the data collection rules configured in the data collection model according to needs.

[0060] In the embodiments of the present invention, the data collection rules of the data collection model can be stored in the form of a configuration file or a plug-in. When it is necessary to organize the device data, the corresponding configuration file or plug-in can be loaded according to the type of the device data, so as to realize the extraction of the data collection rules, and then organize the device data based on the data collection rules.

[0061] Step 240: Extract the substation area identification information, asset number, power supply side asset number, and device attribute information of each electrical device from the device data according to the data collection rule.

[0062] Among them, the substation area identification can be information reflecting the low-voltage substation area to which the electrical device belongs. The substation area identification can specifically be the substation area name or the substation area number. The asset number can be information identifying the user device within the corresponding low-voltage substation area. The asset number can identify the information of the electrical device. The asset number can be information identifying the user device within the low-voltage substation area. The power supply side asset number can be the asset number of the previous user device closer to the power supply side. The power supply side asset number can be used to identify the adjacent relationship between the current user device and the previous user device closer to the power supply side. The device attribute information can be information reflecting the state of the electrical device, and can include information such as the user device type, user number, user name, wire diameter, and position coordinates.

[0063] In the embodiments of the present invention, one or more loaded data collection rules can be used to organize the collected device data, and extract the substation area identification information, asset number, power supply side asset number, and device attribute information, etc. corresponding to each user device from the device data. It can be understood that each user device can have its own corresponding set of information.

[0064] Step 250: Store the substation area identification information, asset number, power supply side asset number, and device attribute information into a preset information table as the topological metadata of the corresponding electrical device.

[0065] Among them, the preset information table can be a data table for storing topological metadata. Each record in the preset information table can correspond to a user device. The preset information table at least includes fields such as substation area identification information, asset number, power supply side asset number, and device attribute information.

[0066] Specifically, the corresponding substation area identification information, asset number, power-side asset number, and device attribute information of each user device can be stored as a record in a preset information table, so that each record in the preset information table can be the topological metadata of an electrical device.

[0067] Step 260: Determine the asset number of the corresponding transformer for each low-voltage substation area, and use the topological metadata corresponding to the asset number as the topological starting point.

[0068] Among them, the transformer can refer to a transformer installed in a certain place, specifically a transformer in operation. Each low-voltage substation area can have its uniquely corresponding transformer. The topological starting point can identify the relationship between the topological metadata of two adjacent electrical devices. The topological starting point can identify the topological metadata of the user device on the power supply side (i.e., the user device closer to the transformer side) among the adjacent electrical devices.

[0069] In the embodiment of the present invention, the asset number of the transformer in each low-voltage substation area can be determined. Within the scope of the low-voltage substation area, this asset number can be used as the starting point of the entire topology. The topological metadata corresponding to this asset number can be searched in the preset information table according to the asset number. For example, a record in the preset information table with the same asset number as this asset number can be used as the topological metadata corresponding to this asset number pair.

[0070] Step 270: Search for the topological metadata with the same power-side asset number as the asset number of the topological starting point and record it as the topological end point, and establish the topological relationship between the topological end point and the topological starting point.

[0071] Among them, the topological end point can identify the relationship between the topological metadata of two adjacent electrical devices. The topological starting point can identify the topological metadata of the user device on the side far from the power supply (i.e., the user device far from the transformer side) among the adjacent electrical devices. The topological relationship can be the position-distance relationship of two adjacent electrical devices relative to the power supply. The topological relationship can specifically be a binary group, including the topological starting point and the topological end point.

[0072] In the embodiment of the present invention, the topological metadata can be searched in the preset information table according to the asset number of the topological starting point. The specific power-side asset number in this topological metadata is the same as the asset number of the topological starting point. The found topological metadata can be used as the topological end point. The topological relationship between the topological starting point and the topological end point can be established. For example, a line can be drawn between the two topological metadata or the same identification information can be established for the two topological metadata.

[0073] Step 280: Use the topological end point as the new topological starting point and repeat the process of searching for the topological end point and establishing the topological relationship until no topological end point can be found.

[0074] In an embodiment of the present invention, the found topology end point can be used as a new topology start point, and the process of step 270 can be repeatedly executed. Starting from the new topology start point, new topology metadata is searched in the preset information standard, so that the asset number on the power supply side of the topology metadata is the same as the asset number of the new topology start point, thereby obtaining a new topology end point, and a new topology relationship is established for the new topology start point and the topology end point. The above process can be repeated until it is impossible to find in the preset information table that the asset number on the power supply side of a topology metadata is the same as the asset number of the found topology metadata.

[0075] Step 290: Connect the corresponding topology metadata in sequence according to each topology relationship to form a low-voltage substation area topology.

[0076] Specifically, the generated multiple topology relationships can be connected in sequence according to the creation order or the distance from the power supply side, so as to connect multiple topology metadata into a low-voltage substation area topology. It can be understood that when the topology relationships are located in multiple low-voltage substation areas, the topology relationships can be connected respectively starting from their corresponding substation transformers, so as to generate corresponding multiple low-voltage substation area topologies.

[0077] In an embodiment of the present invention, by searching for the device data of the electrical equipment in the digital power grid system and collecting the device data of the electrical equipment on-site, reading the data collection rules configured in the data collection rule model, extracting the substation area identification information, asset number, asset number on the power supply side, and device attribute information corresponding to each electrical equipment from the device data according to the data collection rules, and storing them in the preset information table as topology metadata, taking the asset number of the substation transformer of each low-voltage substation area as the start point to obtain the corresponding topology metadata as the topology start point, obtaining the topology metadata with the same asset number on the power supply side as the asset number of the topology start point as the topology end point, determining the topology relationship between the topology start point and the topology end point, taking the topology end point as the new topology start point and repeating the above process until no new topology end point can be obtained, connecting each topology relationship in sequence to process the topology metadata into a low-voltage substation area topology, thereby realizing the automatic generation of the low-voltage substation area topology, facilitating the operation and maintenance of the electrical equipment and lines within the substation area by personnel, reducing the time and difficulty for users to find the location of the equipment, and making it convenient to update the data in the generated digital low-voltage substation area topology, facilitating the update and maintenance of the low-voltage substation area topology during subsequent use.

[0078] Further, on the basis of the above-mentioned invention embodiment, the data collection rules include at least one of the following:

[0079] Extract the substation area name or substation area assessment household number of the current electrical equipment as the substation area identification information;

[0080] Extract the asset number of the current electrical equipment as the asset number;

[0081] Extract the asset number of the previous target power consumption device of the current power consumption device close to the substation it belongs to as the asset number on the power supply side;

[0082] Extract at least one of the device type, the line it belongs to, the power supply station it belongs to, the longitude and latitude it belongs to, the power supply, and the wire diameter of the current power consumption device as the device attribute information.

[0083] In the embodiment of the present invention, different data collection rules can be configured for different device data in the data collection model, and the data collection rules can include at least one of the following: for each power consumption device, use the device asset number of the current power consumption device as the asset number; for each power consumption device, use the asset number of the previous target power consumption device on the side close to the substation it belongs to as the asset number on the power supply side of the current power consumption device; it can also extract at least one of the device type, the line it belongs to, the power supply station it belongs to, the longitude and latitude it belongs to, the power supply, and the wire diameter from the device data of each power consumption device as the device attribute information.

[0084] Further, on the basis of the above-mentioned embodiment of the invention, it further includes: generating a geographical connection diagram corresponding to the low-voltage substation area topology according to the geographical locations in each topological metadata.

[0085] Among them, the geographical location can be the device attribute information included in the topological metadata, which can identify the actual location of the power consumption device in the geography, and the geographical location information can be position coordinates or longitude and latitude.

[0086] In the embodiment of the present invention, the geographical locations in each topological metadata can be extracted, and the low-voltage substation area topology can be mapped to the map according to each geographical location to generate a geographical connection diagram. It can be understood that different topological metadata can adopt the same or different display styles in the geographical connection diagram to determine the actual distance between the corresponding power consumption devices through the distance between different display styles in the geographical connection diagram.

[0087] Further, on the basis of the above-mentioned embodiment of the invention, generating the geographical connection diagram corresponding to the low-voltage substation area topology according to the geographical locations in each of the topological metadata includes:

[0088] Extract the geographical location coordinates of each topological metadata in the low-voltage substation area topology; generate identification icons in the map according to each geographical location coordinate; generate connection lines between each identification icon in the map according to the topological relationship of the low-voltage substation area topology as the geographical connection diagram.

[0089] In an embodiment of the present invention, geographical location coordinates in the topology metadata included in each low-voltage substation area topology can be extracted. The geographical location coordinates can belong to the electricity consumption attribute information of the topology metadata. The corresponding identification icons can be drawn on the map according to the geographical location coordinates of each topology metadata, and then connection lines can be drawn between the identification icons of the corresponding topology metadata according to the topology relationship included in the low-voltage substation area topology, so as to generate a geographical wiring diagram.

[0090] In an exemplary embodiment, a data collection model for the low-voltage substation area can be established in advance, data field information and corresponding acquisition methods can be formulated. Refer to Table 1. In a data collection model, a dual naming method for the collection points is formulated, including an asset number and a power supply side asset number. Among them, the asset side number identifies the asset number of the collection point itself, and the asset number is unique, while the power supply side asset number can be the asset number of the previous collection point extending from the collection point to the power supply. All collection points within the low-voltage substation area record their asset numbers and power supply side asset numbers. In the data fields Asset number and Power supply side Asset number are the keys to the topology relationship of this model and the main data for connecting between each asset number and the topology analysis function. When collecting on-site, the power supply side asset number must be correct, otherwise a correct geographical wiring diagram cannot be generated.

[0091] Table 1. Data Collection Model Field Information and Acquisition Methods

[0092]

[0093]

[0094] In an exemplary embodiment, refer to Figure 3 , all the collection points in the substation area can be connected in pairs through the power supply side asset numbers to generate a low-voltage substation area line topology diagram. The positioning information and topology relationship of all low-voltage devices under the simulated low-voltage substation area are shown in Table 2 below.

[0095] Table 2. Simulated Substation Area Basic Collection Data

[0097] Using the positioning data corresponding to the asset numbers in the above table and the associated positioning data of their power supply side asset numbers, the geographical wiring diagram of the low-voltage substation area can be automatically drawn on the map.

[0098] The drawing method is as follows:

[0099] Use the longitude and latitude [Ax, Bx] of the asset numbers from 1 to 17 to draw icons on the map.

[0100] Draw the connection lines between the coordinate points using the corresponding positioning data in the two columns of asset number and power supply side asset number. The connection method between each coordinate point is as follows:

[0101] Connect 1 to 1 [[A1,B1],[A1,B1]],

[0102] Connect 2 to 1 [[A2,B2],[A1,B1]],

[0103] Connect 3 to 2 [[A3,B3],[A2,B2]],

[0108] See Figure 4 , and so on to draw the lines in sequence. The generated geographical wiring diagram will be able to restore the actual wire connection method on site.

[0109] Embodiment 3

[0110] Figure 5 is a flowchart of a low-voltage topology generation method provided according to Embodiment 3 of the present invention. The embodiments of the present invention are specific on the basis of the above-mentioned invention embodiments and are used to illustrate the use of the low-voltage substation area topology. See Figure 5 , and the method provided by the embodiments of the present invention specifically includes the following steps:

[0111] Step 310: Obtain the device data of the electrical equipment in each low-voltage substation area.

For example, the specified electrical equipment can be selected by inputting the identification information of the electrical equipment or the name of the electrical equipment. The power supply traceability path can be a topology path for an electrical equipment to reach the substation transformer of the low-voltage substation area to which it belongs, and the power supply traceability path can be a part of the low-voltage substation area topology.

[0116] In an embodiment of the present invention, a topological path from the specified power consumption device to the substation can be found in the low-voltage substation area topology according to the specified power consumption device selected by the user.

[0117] Further, based on the above embodiment of the invention, determining a power source tracing path according to the specified power consumption device and the low-voltage substation area topology includes:

[0118] Obtain the specified asset number of the specified power consumption device; find the topological metadata with the same asset number as the specified asset number in the low-voltage substation area topology, and record the topological metadata as the tracing starting point; use the topological relationship between the tracing starting point and the topological metadata corresponding to the substation in the low-voltage substation area as the power source tracing path.

[0119] Among them, the specified asset number can be the asset number of the specified power consumption device, and the specified asset number can be input by the user.

[0120] Specifically, the specified asset number input by the user can be obtained, the topological metadata with the asset number being the specified asset number can be found in the low-voltage substation area topology, this topological metadata can be used as the tracing starting point for determining the power source tracing path, and the topological relationship between this tracing starting point and the topological metadata corresponding to the substation in the low-voltage substation area can be used as the power source tracing path of the specified power consumption device.

[0121] Further, based on the above embodiment of the invention, it further includes:

[0122] Extract the topological relationships included in the power source tracing path, and determine the position distance according to the longitude and latitude of the two topological metadata corresponding to each topological relationship; use the sum of each position distance as the path distance of the power source tracing path.

[0123] In an embodiment of the present invention, after determining the power source tracing path, the path distance from the specified power consumption device to the substation can also be determined. Specifically, the topological relationships included in the power source tracing path can be extracted, the longitude and latitude of the two topological metadata corresponding to each topological relationship can be extracted, the distance between the two longitudes and latitudes can be used as the position distance of this topological relationship, the determined position distances corresponding to each topological relationship can be summed, and the sum of each position distance can be used as the path distance of the power source tracing path.

[0124] In an exemplary implementation manner, Figure 6FIG. 0 is an exemplary diagram of a power tracing path provided according to Embodiment 3 of the present invention. In the embodiments of the present invention, power tracing refers to calculating, in a geographical wiring diagram, the line path from a meter along a low-voltage line to a transformer, and can also determine the straight-line distance between the meter and the transformer and the path distance of the meter along the low-voltage line to the transformer. Specifically, in the low-voltage substation topology, starting from asset number A, find the power-side asset number B recorded in the topological metadata of A, then find the power-side asset number C recorded in the topological metadata of B, and so on, until the asset number is the same as the power-side asset number, at which point the tracing path calculation is completed. Refer to Figure 5 , perform power tracing on the 13th collection point in the topological data of the simulated substation area 1 in Table 2. The power-side asset number of 13 is 15, the power-side asset number of 15 is 4, the power-side asset number of 4 is 5, the power-side asset number of 5 is 2, the power-side asset number of 2 is 1, and the power-side asset number of 1 is 1. Stop searching, the path calculation is completed, and the path obtained is 13-15-4-5-2-1.

[0125] After obtaining the power path, the distance between two points can also be calculated through longitude and latitude coordinates. The straight-line distance refers to the straight-line distance between the coordinates of 13 and 1, and the path distance refers to the path length of 13-15-4-5-2-1. Calculate the distances of 13-15, 15-4, 4-5, 5-2, and 2-1 respectively, and the sum is the path distance, as shown in Figure 6 the virtual line path in.

[0126] Embodiment 4

[0127] Figure 7 FIG. 14 is a flowchart of a method for generating a low-voltage substation topology provided according to Embodiment 4 of the present invention. The embodiments of the present invention are specific implementations based on the above-mentioned embodiments of the invention, and load analysis is realized based on the low-voltage substation topology. Refer to Figure 7 , the method provided by the embodiments of the present invention specifically includes the following steps:

[0128] Step 410, obtain the device data of the electrical equipment in each low-voltage substation area.

[0129] Step 420, determine the topological metadata corresponding to each electrical equipment according to the data collection model and the device data.

[0130] Step 430, organize the topological metadata into a low-voltage substation topology according to the power consumption sequence of each electrical equipment to the corresponding low-voltage substation area.

[0131] Step 440, determine the power load according to the specified electrical equipment and the low-voltage substation topology.

[0132] Among them, the power load can start from a certain electrical device, including the quantity and list of the electrical device and the electrical devices behind the branch line.

[0133] In the embodiment of the present invention, other electrical devices after the electrical device can be searched starting from the electrical device in the low-voltage substation area topology, and the total number and list of other electrical devices can be counted as the power load of the specified electrical device.

[0134] Further, on the basis of the above-mentioned embodiment of the invention, determining the power load according to the specified electrical device and the low-voltage substation area topology includes:

[0135] Obtain the specified asset number of the specified electrical device; search in the low-voltage substation area topology for the topology metadata with the same asset number as the specified asset number and record it as the load starting point; search in the low-voltage substation area topology for the topology metadata with the same power-side asset number as the asset number of the load starting point as the power load of the load starting point; use the topology metadata corresponding to the power load as the new load starting point, and repeat the process of searching for the power load until the power load of the load starting point cannot be found.

[0136] In the embodiment of the present invention, the specified asset number of the specified user device input by the user can be obtained first. The topology metadata with the asset number being the specified asset number can be found in the low-voltage substation area topology. This topology metadata can be used as the load starting point for determining the power load. The topology metadata with the same power-side asset number as the asset number of the symbol starting point can be found in the low-voltage substation area topology. This topology metadata can be recorded as the power load. This power load can be used as the new load starting point to repeat the above process of searching for the topology metadata until the power load corresponding to the load starting point cannot be obtained in the low-voltage substation area topology. The topology metadata found in the above process can be used as the power load of the corresponding specified electrical device.

[0137] In an exemplary embodiment, taking the power load statistics of the electric meter as an example, Figure 8 is an example diagram of a power load provided according to Embodiment 4 of the present invention. The search for the power load can include: starting from A, finding B with the power-side asset number recorded as A, then finding C with the power-side asset number being B, then finding D with the power-side asset number being C, and so on. Stop when the found asset number cannot be found in the power-side asset number. Finally, obtain the number of electric meters and the list of electric meters. For example, see Figure 8, perform a load analysis on the collection point No. 3 in the topological data of the simulated substation area 1 in Table 2. Find that the asset numbers with the power supply side asset number 3 are 6 and 10. Then find that the asset numbers with the power supply side asset number 6 or 10 are 7, 8, and 11. Then find that the asset numbers with the power supply side asset number 7 or 8 or 11 are 9 and 16. Then find that the asset number with the power supply side asset number 9 or 16 is 17. Finally, find that there is no asset number with the power supply side asset number 17, and the load analysis ends.

[0138] Among them, the merged asset number list is [3, 6, 10, 7, 8, 11, 9, 16, 17], a total of 9.

[0139] Embodiment 5

[0140] Figure 9 is a flowchart of a low-voltage substation area topology generation method provided according to Embodiment 5 of the present invention. The embodiment of the present invention is a specific implementation based on the above-mentioned embodiment of the invention, and details the update process of the low-voltage substation area topology. Refer to Figure 9 , the method provided by the embodiment of the present invention specifically includes the following steps:

[0141] Step 510: Obtain the device data of the electrical equipment in each low-voltage substation area.

[0142] Step 520: Determine the topological metadata corresponding to each electrical equipment according to the data collection model and the device data.

[0143] Step 530: Organize the topological metadata into a low-voltage substation area topology according to the power consumption sequence of each electrical equipment to the corresponding low-voltage substation area.

[0144] Step 540: Update the low-voltage substation area topology according to the topology adjustment information.

[0145] Among them, the topology adjustment information can be information for adjusting the low-voltage substation area topology, and can include information for deleting user equipment or information for splitting part of the load in the low-voltage substation area topology.

[0146] In the embodiment of the present invention, the topology adjustment information can be received, and based on the topology adjustment information, the topological metadata of the electrical equipment in the low-voltage substation area topology can be deleted or part of the load in the low-voltage substation area topology can be split.

[0147] In one embodiment, the topology adjustment information can be load splitting information for load splitting. Updating the low-voltage substation area topology according to the topology adjustment information includes:

[0148] Step 5410: Obtain the load splitting information in the topology adjustment information, where the load splitting information at least includes a first substation area access point, a second substation area access point, and a substation area splitting point.

[0149] Among them, the load segmentation information can be used to control the information for segmenting the load in the low-voltage substation area topology. Load segmentation can refer to splitting the user equipment of one substation into another substation. Correspondingly, some topological metadata in the low-voltage substation area topology needs to be added to another low-voltage substation area topology. The first substation access point can be the electrical equipment in the low-voltage substation area topology to be segmented that needs to be connected to the low-voltage substation area topology to be accessed. The first substation access point can specifically be the asset number of the electrical equipment, while the second substation access point can be the electrical equipment at the position in the low-voltage substation area topology to be accessed that is connected to the low-voltage substation area topology to be segmented. The substation splitting point can be the position for splitting the topological metadata in the low-voltage substation area topology to be segmented, which can be represented by the asset number of the user equipment.

[0150] In the embodiment of the present invention, the first substation access point, the second substation access point, and the substation splitting point for load segmentation can be obtained as the load segmentation information, and this load segmentation information can be used to adjust the low-voltage substation area topology.

[0151] Step 5420: Search for the topological metadata to be adjusted as the power load in the corresponding low-voltage substation area topology according to the first substation access point.

[0152] Among them, the topological metadata to be adjusted can be the topological metadata of the user equipment split out from the low-voltage substation area topology.

[0153] Specifically, the topological metadata can be searched in the low-voltage substation area topology starting from the first substation access point as the power load, and the searched topological metadata can be used as the topological metadata to be adjusted. It can be understood that the process of determining the power load can be implemented in the manner of the above embodiment.

[0154] Step 5430: Set the substation identification information of the topological metadata to be adjusted as the substation identification information of the second substation access point.

[0155] Among them, the substation identification information can be the information reflecting the low-voltage substation area to which the user equipment belongs, and can include the low-voltage substation area number or the low-voltage substation area name.

[0156] In the embodiment of the present invention, the topological metadata of the second substation access point can be searched in the low-voltage substation area topology, the substation identification information of the low-voltage substation area to which the user equipment belongs can be extracted from the topological metadata, and the substation identification information in each topological metadata to be adjusted obtained in the previous process can be set as the extracted substation identification information.

[0157] Step 5440: Determine the direction adjustment topological metadata in the topological metadata to be adjusted whose topological relationship is between the substation splitting point and the first substation access point.

[0158] Among them, the direction adjustment topology metadata may be the topology metadata that needs to adjust the substation transformation direction of the user device, and the direction adjustment topology metadata may need to adjust the content of the power supply side asset number in the topology metadata.

[0159] In the embodiment of the present invention, it is possible to judge the topology metadata to be adjusted to determine whether the topology metadata to be modulated is located between the substation splitting point and the first substation access point in the low-voltage substation area topology. If a topology metadata to be adjusted is located between the substation splitting point and the first substation access point, then the topology metadata to be adjusted is recorded as the direction adjustment topology metadata.

[0160] Step 5450: Clear the power supply side asset number of the topology metadata at the substation splitting point and set the power supply side asset number of the topology metadata at the first substation access point to the asset number of the second substation access point.

[0161] Specifically, it is possible to search for the topology metadata at the substation splitting point in the low-voltage substation area topology, delete the power supply side asset number in the topology metadata, and extract the asset number of the second substation access point. The power supply side asset number of the topology metadata at the first substation access point can be set to the extracted asset number.

[0162] Step 5460: Determine the topology relationships corresponding to each direction adjustment topology metadata, and set the power supply side asset number of the topology metadata at the topology start point in the corresponding topology relationship to the asset number of the topology metadata at the topology end point in the same topology relationship.

[0163] In the embodiment of the present invention, it is possible to search for the topology relationships corresponding to each direction adjustment topology metadata in the low-voltage substation area topology. The topology relationship may include two topology metadata, where one may be the topology start point and the other may be the topology end point. For each topology relationship, the power supply side asset number of the topology metadata at the topology start point can be set to the asset number of the topology metadata at the topology end point in the same topology relationship.

[0164] In an exemplary implementation, it is possible to perform load segmentation on the low-voltage substation area topology. Load segmentation refers to splitting some users of transformer 1 to transformer 2. Only three points of the load segmentation need to be known: which post-metering load of transformer 1 is split to transformer 2, which meter of transformer 1 is connected to transformer 2, and which meter of transformer 2 is connected. The load segmentation algorithm can maintain the correctness of the power connection relationship, automatically maintain the power supply side asset number of the meters split to the new transformer, automatically obtain the user list of the load segmentation, and modify the affiliated substation area to the new transformer. Table 3 shows the basic data of the simulated substation area 2 symbol splitting access point

[0167] See Figure 10a , in the simulation table 2, the load of the transformer substation 1 behind No. 3 is split to the transformer substation 2 and connected to No. 18 of the transformer substation 2 from No. 17. The process of load splitting includes the following steps:

[0168] (1) Obtain the list of users split into the new transformer area. Through the load splitting algorithm in this article, obtain the electricity meter list starting from No. 3 as array A: [3, 6, 10, 8, 7, 11, 9, 16, 17].

[0169] (2) Trace the power source from No. 17 until it stops at No. 3, and obtain the path list as 17 - 16 - 11 - 10 - 3, and obtain array B: [17, 16, 11, 10, 3].

[0170] (3) Modify the transformer area to which the array A in step (1) belongs to the transformer substation 2, and obtain the lists of the split transformer substation 1 and transformer substation 2 as shown in the following tables 4 and 5.

[0175] (4) Create a new array C, place the connection point 18 of the transformer substation 2 at the first element of the array, delete the last element of the array B, and add it successively behind 18 of the array C to obtain the array C:

[0176] [18, 17, 16, 11, 10]. Traverse the elements of the array B, and modify the elements of the C array to the power source side asset numbers corresponding to the elements of the B array. The corresponding relationship between the asset numbers and the power source side asset numbers is shown in Table 6.

[0179] The modified topological data of the transformer substation 2 is shown in Table 7.

[0182] The load splitting is completed. The new low - voltage line topological diagram of the transformer area is as Figure 10bas shown

[0183] In one embodiment, updating the low-voltage station area topology according to the topology adjustment information includes:

[0184] Obtain the device addition information in the topology adjustment information, where the device addition information at least includes the access location and the newly added device; determine the first topology metadata and the second topology metadata corresponding to the access location in the low-voltage station area topology, where the asset number on the power supply side of the second topology metadata is the asset number of the first topology metadata; add the newly added topology metadata of the newly added device to the low-voltage station area topology, and set the asset number on the power supply side of the newly added topology metadata to the asset number of the first topology metadata; in the low-voltage station area topology, set the asset number on the power supply side of the second topology metadata to the asset number of the newly added topology metadata.

[0185] Among them, the device addition information can be the information of newly added user devices, and can include the relevant information of the newly added user devices and the location where the newly added device is added to the low-voltage station area topology. The access location can be identified by the asset number of the user device, and the newly added user device can be added after or before the user device in the low-voltage station area topology.

[0186] In the embodiments of the present invention, the user can input the access location and the newly added device as the device addition information, can find the first topology metadata corresponding to the user device after the newly added device and the second topology metadata corresponding to the user device before the newly added device in the low-voltage station area topology according to the access location, can add the newly added topology metadata corresponding to the newly added device to the low-voltage station area topology, and set the asset number on the power supply side of the newly added topology metadata to the asset number of the second topology metadata of the user device before the newly added device, and set the asset number on the power supply side of the first topology metadata of the user device after the newly added device to the asset number of the newly added topology metadata of the newly added device.

[0187] In an exemplary embodiment, for the case of installing a new meter between the main lines of two meters, when it is impossible to accurately judge which side is the power direction on site, to prevent incorrect power association when manually maintaining the wiring diagram, for example, when a new meter C is installed between meter A and meter B on site, the algorithm first needs to judge the relationship between meter A and meter B. If the asset number on the power supply side of meter A is meter B, the new power association relationship is automatically maintained as:

[0188] (1) Set the asset number on the power supply side of meter C to meter B,

[0189] (2) Set the asset number on the power supply side of meter A to meter C,

[0190] (3) The asset number on the power supply side of meter B remains unchanged.

[0191] If the asset number on the power supply side of meter B is meter A, then the new power supply association relationship is automatically maintained as:

[0192] (4) Set the asset number on the power supply side of meter C to meter A,

[0193] (5) Set the asset number on the power supply side of meter B to meter C,

[0194] (6) The asset number on the power supply side of meter A remains unchanged.

[0195] After the asset number on the power supply side is re-maintained, ensure the correctness of the topological relationship.

[0196] For example, in the topology diagram of analog substation transformer 1 in Table 2, on-site, a jumper wire needs to be connected between No. 4 and No. 15 to the service drop wire, and a new meter No. 20 is installed, as Figure 11a shown. When the meter reader collects the positioning data of No. 20, the submitted data includes No. 4 and No. 15. By judging the substation area topology data, the relationship between No. 4 and No. 15 is obtained as: the asset number on the power supply side of No. 15 is No. 4, then set the asset number on the power supply side of No. 20 to No. 4, and set the asset number on the power supply side of No. 15 to No. 20. Wait until the new substation area topology data is shown in Table 8.

[0199] Get the new low-voltage line topology diagram of the substation area as Figure 11b shown.

[0200] In an exemplary embodiment, updating the low-voltage substation area topology according to the topology adjustment information includes:

[0201] Obtain the device deletion information in the topology adjustment information; search for and delete the deleted topology metadata corresponding to the device deletion information in the low-voltage substation area topology; obtain the third topology metadata in the low-voltage substation area topology whose asset number on the power supply side is the same as that of the deleted topology metadata; obtain the fourth topology metadata in the low-voltage substation area topology whose asset number is the same as the asset number on the power supply side of the deleted topology metadata; set the asset number on the power supply side of the third topology metadata to the asset number of the fourth topology metadata.

[0202] Among them, the device deletion information can be the information of the user device to be deleted, and the device deletion information can be the asset number of the user device. The deleted topology metadata can be the topology metadata to be deleted in the low-voltage substation area topology. The third topology metadata can be the topology metadata in the low-voltage substation area topology before the deleted topology metadata, and the fourth topology metadata can be the topology metadata in the low-voltage substation area topology after the deleted topology metadata.

[0203] In an embodiment of the present invention, it is possible to receive device deletion information input by a user, search for topological metadata corresponding to the device deletion information in the low-voltage substation area topology as the deletion topological metadata, delete the deletion topological metadata in the low-voltage substation area topology, extract third topological metadata in the low-voltage substation area topology, and set the asset number on the power supply side of the third topological metadata as the asset number of the fourth topological metadata.

[0204] In an exemplary embodiment, for the case of closing an account for a meter between the main lines of two meters, it is necessary to maintain the asset numbers on the power supply sides of the front and rear meters, reconnect the geographical wiring diagram, and ensure the correctness of the topological relationship. For example, if the asset number on the power supply side of the meter A to be closed is meter B, and the asset number on the power supply side of meter C is meter A, when deleting the file of meter A, it is necessary to set the asset number on the power supply side of meter C to meter B. The simulation of closing an account for a meter in substation area 1 is as Figure 12a shown. When closing the account for meter No. 4, searching the topological data of the substation area to obtain that the asset number on the power supply side of No. 4 is No. 5, and the meter with the asset number on the power supply side of No. 4 being No. 15, then set the asset number on the power supply side of No. 15 to No. 5. The new topological data of the substation area is shown in Table 9, and the new low-voltage line topological diagram of the substation area is as Figure 12b shown.
