Description

Technical Field

[0001] The present application relates to, but is not limited to, the field of power grid technology, and in particular to a method for generating a full network topology of a distribution network and electronic equipment. Background Art

[0002] The urban distribution network is a power supply network that uses substations as power sources and connects all distribution lines together through interconnection switches. The existing urban distribution network topology splicing method is to store the modeling data related to the entire urban distribution network (such as substation wiring diagrams and distribution line single-line diagrams, etc.) in a database through the distribution automation master station system (DAS system), and generate a full network topology model by splicing the substation wiring diagram and the distribution line single-line diagram in pairs. The traditional DAS system splices the local topology diagram through connection points. It is necessary to set attributes for the interconnection switch SWLL in the diagram to mark which end of the line is connected to the interconnection switch. For example, when implementing a single-line Figure 1 Line LINEa2, single line Figure 2 When the line LINEb2 is connected to the tie switch SWLL, it is necessary to record on the SWLL of the two single-line diagrams that LINEa2 is connected to the left end of SWLL and LINEb2 is connected to the right end of SWLL, which makes the diagram model maintenance work very cumbersome; when interacting with other systems such as PMS, other systems are required to provide connection information of the connection points on the opposite side of the splicing device, which increases the processing complexity of other systems; in summary, the existing full-network topology generation method leads to high network management costs and poor network flexibility of the full-network topology. Summary of the invention

[0063] The urban distribution network is a power supply network that uses substations as power sources and connects all distribution lines together through interconnection switches. The existing urban distribution network topology splicing method is to store the modeling data related to the entire urban distribution network (such as substation wiring diagrams and distribution line single-line diagrams, etc.) in a database through the distribution automation master station system (DAS system), and generate a full network topology model by splicing the substation wiring diagram and the distribution line single-line diagram in pairs. The traditional DAS system splices the local topology diagram through connection points. It is necessary to set attributes for the interconnection switch SWLL in the diagram to mark which end of the line is connected to the interconnection switch. For example, when implementing a single-line Figure 1 Line LINEa2, single line Figure 2 When the line LINEb2 is connected to the tie switch SWLL, it is necessary to record on the SWLL of the two single-line diagrams that LINEa2 is connected to the left end of SWLL and LINEb2 is connected to the right end of SWLL, which makes the diagram model maintenance work very cumbersome; when interacting with other systems such as PMS, other systems are required to provide connection information of the connection points on the opposite side of the splicing device, which increases the processing complexity of other systems; in summary, the existing full-network topology generation method leads to high network management costs and poor network flexibility of the full-network topology.

[0064] In order to solve the above-mentioned problems, the embodiments of the present application provide a method, device, equipment, and medium for generating the full network topology of a distribution network, the method comprising: obtaining a plurality of modeling diagrams to be spliced, wherein each of the modeling diagrams corresponds to a device to be spliced, and the types of the modeling diagrams include substation wiring diagrams and single-line diagrams; obtaining a preset connection point associated device table and a topology device table, wherein the connection point associated device table is used to indicate the mapping relationship between the connection point and the connected device and the target modeling diagram, the target modeling diagram is the modeling diagram to which the connection point belongs, and the topology device table is used to indicate the mapping relationship between the device and the connection point; based on the connection point associated device table, the topology device table, and the substation wiring diagram corresponding to the device, the mapping relationship between the device and the connection point is obtained. The first device connection group constructs the substation topology, wherein the first device connection group is used to indicate at least two interrelated devices in the substation wiring diagram, and the devices in the first device connection group correspond to a first connection point; based on the connection point associated device table, the topology device table and the second device connection group corresponding to the single-line diagram, the distribution line topology and the substation topology are spliced ​​to generate the full network topology of the target distribution network, wherein the second device connection group is used to indicate at least two interrelated devices in the single-line diagram, and the devices in the second device connection group correspond to a second connection point, and the current data in the connection point associated device table and the topology device table correspond to the full network topology of the target distribution network. According to the scheme provided in the embodiment of the present application, the full network topology is generated based on the modeling diagram to be spliced ​​and the updatable connection point associated device table and topology device table, without the need for additional fixed settings of the splicing position information between the devices to be spliced, effectively reducing the network management cost of the full network topology of the distribution network, and improving the network flexibility of the generated full network topology.

[0065] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0066] refer to Figure 1 , Figure 1 The present invention provides a method for generating the full network topology of a distribution network, which includes but is not limited to the following steps:

[0067] Step S10, obtaining a plurality of modeling diagrams to be spliced, wherein each modeling diagram corresponds to a device to be spliced, and the types of modeling diagrams include substation wiring diagrams and single-line diagrams.

[0068] Specifically, the modeling diagram of this embodiment refers to a wiring diagram that is completely consistent with the model. The modeling diagram fully records the connection relationship between the devices. The DAS system modeling can be realized through the modeling diagram. The modeling diagram of the embodiment of the present application includes two types: substation wiring diagram and single-line diagram. The specific form of the substation wiring diagram of this embodiment is as follows: Figure 5 and Figure 6 As shown, the single-line diagram is Figure 3 and Figure 4 shown.

[0069] Specifically, the devices to be spliced ​​in this embodiment are devices that can realize the splicing of modeling graphs in pairs and form the topology of the entire network. The devices to be spliced ​​exist in both modeling graphs with an associated relationship, for example Figure 3 As shown, the devices to be spliced ​​in the first single-line diagram FDRa are the outgoing line switch FCBa1 and the tie switch SWLL.

[0070] Specifically, the device connection group of this embodiment is a group of related devices in the modeling diagram. The device connection group and the connection point correspond one to one. Based on the device connection group, a connection point identifier (i.e., connection point ID) can be generated. It should be noted that this embodiment also needs to set the table flag bFCBJ=TRUE for the load-side device connection group of the substation outgoing switch in the substation wiring diagram and the single-line diagram, in order to provide effective support for the subsequent splicing of the substation topology and the distribution line topology. For example, Figure 3 As shown, the connection lines LINEa2 and SWLL in the first single-line diagram FDRa form a first device connection group, FCBa1 and the connection line LINEa1 form another first device connection group, and the table mark bFCBJ corresponding to each first device connection group is TRUE; the specific method of setting the mark is to perform a topological search on the devices in the device connection group of the associated outgoing line switch, and the device connection group for which the busbar cannot be found is marked with a table mark.

[0071] Step S20, obtaining a preset connection point associated device table and a topology device table, wherein the connection point associated device table is used to indicate the mapping relationship between the connection point and the connected device to be spliced ​​and the target modeling diagram, the target modeling diagram is the modeling diagram to which the connection point belongs, and the topology device table is used to indicate the mapping relationship between the device and the corresponding connection point.

[0072] Specifically, the connection point associated device table of this embodiment is used to indicate the mapping relationship between the connection point and the connected device and the target modeling diagram, with the purpose of recording the connection point identifiers on different devices of different modeling diagrams.

[0073] The connection point associated device table of this embodiment is specifically shown in Table 1:

[0074] Table 1 Connection point associated equipment table

[0075]

[0076]

[0077] Specifically, the topology device table of this embodiment is used to indicate the mapping relationship between the device and the corresponding connection point, and can provide an effective data basis for the subsequent splicing of the point to be spliced ​​and the SWLL.

[0078] Specifically, the connection points of this embodiment include power connection points and load connection points, and the topology device table is specifically shown in Table 2:

[0079] Table 2 Topology equipment table

[0080] Device Name Equipment identification INODE JNODE FCBa1 FCBa1ID CN0 CN1 FCB1 FCBb1ID CN9 CN8 SWa1 SWA1D CN2 CN3 SWb1 SWb1ID CN7 CN6 SWLL SWLLID CN4 CN5 LINEa1 LINEa1ID CN1 CN2 LINEa2 LINEa2ID CN3 CN4 LINEb1 LINEb1ID CN8 CN7 LINEb2 LINEb2ID CN6 CN5 ……

[0081] Among them, each device corresponding to the device name in the topology device table of Table 2 corresponds to a power connection point and a load connection point, INODE is the identifier of the power connection point of the device corresponding to the device name, and JNODE is the identifier of the load connection point of the device corresponding to the device name.

[0082] It can be understood that after this embodiment constructs the substation topology based on the connection point associated equipment table, the topology equipment table and the first equipment connection group corresponding to the substation wiring diagram, the second equipment connection group corresponding to the single-line diagram and the corresponding in-station equipment in the substation topology are realized through the connection point associated equipment table and the topology equipment table after the substation topology is updated, and the distribution line topology is generated. Then, the whole network topology is obtained through the connection point associated equipment table and the topology equipment table after the distribution line topology is updated, and the SWLL splicing of the mutually related distribution line topologies is used, that is, the whole network topology splicing is realized based on the local graphics.

[0083] Step S30, constructing a substation topology based on the connection point associated device table, the topology device table and the first device connection group corresponding to the substation wiring diagram, wherein the first device connection group is used to indicate at least two interrelated devices in the substation wiring diagram, and the devices in the first device connection group correspond to the first connection point.

[0084] Specifically, in some embodiments, the substation topology is constructed based on the connection point associated device table, the topology device table and the first device connection group corresponding to the substation wiring diagram, that is, Figure 1 Step S30 includes but is not limited to the following steps:

[0085] Step S31, determining a first target connection point based on the connection point associated device table, the topology device table and the first device connection group;

[0086] It is understandable that step S31 of this embodiment includes but is not limited to the following steps:

[0087] Step S311, determining a first reference device corresponding to each first connection point from a connection point associated device table;

[0088] Step S312, when the first reference device is the same as the first device, determining the first connection point as the first target connection point;

[0089] or,

[0090] Step S313, when the first reference device is different from the first device, and the first device connection group corresponding to the first device is a device connection group on the FCB load side, a first reference load connection point corresponding to the first device connection group is determined from the topology device table, and the first reference load connection point is determined as the first target connection point;

[0091] or,

[0092] Step S314: When the first reference device is different from the first device, and the first device connection group corresponding to the first device does not belong to the device connection group on the FCB load side, a first target connection point is generated for the first device connection group, and the first target connection point is different from the connection point corresponding to the first device connection group in the topology device table.

[0093] Step S32, taking the connection point corresponding to the main transformer TF side of the substation wiring diagram as the search starting point, a topological search is performed on the first target connection point in the direction of the outgoing line switch FCB of the substation wiring diagram, and the first target load connection point and the first target power connection point corresponding to the first device in the first device connection group are determined;

[0094] Step S33: updating the connection point associated device table and the topology device table based on the connection point identifiers corresponding to the first target load connection point and the first target power source connection point, so as to complete the construction of the substation topology.

[0095] It can be understood that in the process of constructing the substation topology of this embodiment, it is necessary to read the graphic data of the corresponding substation wiring diagram, determine the first device connection group corresponding to the substation wiring diagram, and determine the first splicing device list corresponding to the substation wiring diagram, and set the flag bFCBJ=TRUE for the first device connection group on the load side connected with the splicing device (such as the outgoing line switch FCB); then read the data in the current connection point associated device table and the topology device table, and construct the substation topology based on the connection point associated device table, the topology device table and the first device connection group corresponding to the substation wiring diagram. The specific steps include: determining the first target connection point based on the connection point associated device table, the topology device table and the first device connection group; taking the connection point corresponding to the main transformer TF side of the substation wiring diagram as the search starting point, performing a topological search on the first target connection point in the direction of the outgoing line switch FCB of the substation wiring diagram, and determining the first target load connection point and the first target power connection point corresponding to the first device in the first device connection group; updating the connection point associated device table and the topology device table based on the connection point identifiers corresponding to the first target load connection point and the first target power connection point to complete the construction of the substation topology.

[0096] In the process of determining the first target connection point based on the connection point associated device table, the topology device table and the first device connection group, the embodiment of the present application takes into account the following three situations: (1) when the first reference device is the same as the first device, the first connection point is determined as the first target connection point, that is, the corresponding connection point ID in the connection point associated device table is reused; (2) when the first reference device is different from the first device, and the first device connection group corresponding to the first device in the substation wiring diagram is the device connection group on the FCB load side, the first reference load connection point corresponding to the first device connection group is determined from the topology device table, and the first reference load connection point is determined as the first target connection point, that is, the FCB load side is reused. The connection point ID corresponding to the device connection group is obtained, and the off-site devices associated with the connection point ID are spliced; (3) when the first reference device is different from the first device, and the first device connection group corresponding to the first device does not belong to the device connection group on the FCB load side, a first target connection point is generated for the first device connection group, and the first target connection point is different from the connection point corresponding to the first device connection group in the topology device table, that is, the device connection group regenerates a suitable connection point ID as the first target connection point. So far, under different circumstances (including consistency and inconsistency between graphic data and preset data table data), the success rate of substation topology construction can be maximized to avoid errors in the subsequent construction of the entire network topology.

[0097] Step S40, based on the connection point associated device table, the topology device table and the second device connection group corresponding to the single-line diagram, complete the splicing of the distribution line topology and the substation topology, and generate the full network topology of the target distribution network, wherein the second device connection group is used to indicate at least two interrelated devices in the single-line diagram, and the devices in the second device connection group correspond to the second connection point, and the data in the current connection point associated device table and the topology device table correspond to the full network topology of the target distribution network.

[0098] Specifically, the entire network topology of this embodiment is generated by a graphics-driven model, which can effectively avoid modeling errors and improve the ease of modeling.

[0099] In some embodiments, Figure 1 Step S40 includes but is not limited to the following steps:

[0100] Step S41, determining a second target connection point based on the connection point associated device table, the topology device table and the second device connection group;

[0101] Step S42, taking the load side connection point of the substation outlet switch FCB in the single-line diagram as the search starting point, and performing a topological search for the second target connection point in the direction of the tie switch SWLL in the single-line diagram, to determine the second target load connection point and the second target power connection point corresponding to the second device in the second device connection group;

[0102] Step S43, based on the connection point identifiers corresponding to the second target load connection point and the second target power connection point, the connection point associated device table and the topology device table are updated to complete the construction of the distribution line topology to be spliced, wherein the number of distribution line topologies is at least 2, each distribution line topology corresponds to a target splicing point, and the target splicing point is used to splice the SWLL;

[0103] Step S44, the target splicing point is spliced ​​with the SWLL to obtain the full network topology of the target distribution network.

[0104] In some embodiments, step S41 includes but is not limited to the following steps:

[0105] Step S411, determining a second reference device corresponding to each second connection point from the connection point associated device table;

[0123] Specifically, when the substation topology is completed, the distribution line topology needs to be constructed first in the process of constructing the whole network topology of this embodiment. Specifically, the steps of constructing the distribution line topology are as follows: it is necessary to read the graphic data of the corresponding single-line diagram, determine the second device connection group corresponding to the single-line diagram, and determine the second splicing device list corresponding to the single-line diagram, and set the flag bFCBJ=TRUE for the second device connection group on the load side connected to the splicing device (such as the outgoing line switch FCB); then read the data in the current connection point associated device table and the topology device table, complete the splicing of the distribution line topology and the substation topology based on the connection point associated device table, the topology device table and the second device connection group corresponding to the single-line diagram, and generate the whole network topology of the target distribution network. The specific steps include: based on the connection point associated device table , topology device table and the second device connection group to determine the second target connection point; taking the load side connection point of the substation outlet switch FCB in the single-line diagram as the search starting point, and performing a topological search for the second target connection point in the direction of the connecting switch SWLL in the single-line diagram, to determine the second target load connection point and the second target power connection point corresponding to the second device in the second device connection group; based on the connection point identifier corresponding to the second target load connection point and the second target power connection point, the connection point associated device table and the topology device table are updated to complete the construction of the distribution line topology to be spliced, wherein the number of distribution line topologies is at least 2, and each distribution line topology corresponds to a target splicing point, and the target splicing point is used to splice SWLL; the target splicing point is spliced ​​with SWLL to obtain the full network topology of the target distribution network.

[0124] Among them, in the process of selecting the second target connection point for constructing the topology of the distribution line to be spliced, that is, in the process of determining the second target connection point based on the connection point associated device table, the topology device table and the second device connection group, it is necessary to determine the second reference device corresponding to each second connection point from the connection point associated device table. The embodiment of the present application takes into account the following three situations: (1) When the second reference device is the same as the second device, the second connection point is determined as the second target connection point, that is, the corresponding connection point ID in the connection point associated device table is reused; (2) When the second reference device is different from the second device, and the second device connection group corresponding to the second device is the device connection group on the FCB load side, the second reference device is determined as the second target connection point from the topology device table. The second reference load connection point corresponding to the second device connection group is determined in the topology device table, and the second reference load connection point is determined as the second target connection point, that is, the connection point ID corresponding to the device connection group on the FCB load side is reused, and the substation devices associated with the connection point ID are spliced; (3) when the second reference device is different from the second device, and the second device connection group corresponding to the second device does not belong to the device connection group on the FCB load side, a second target connection point is generated for the second device connection group, and the second target connection point is different from the connection point corresponding to the second device connection group in the topology device table, that is, the device connection group regenerates a suitable connection point ID as the second target connection point.

[0125] After the second target connection point is determined, the load side connection point of the substation outlet switch FCB in the single-line diagram is used as the search starting point, and a topological search is performed on the second target connection point in the direction of the connecting switch SWLL in the single-line diagram to determine the second target load connection point and the second target power connection point corresponding to the second device in the second device connection group. In this process, the embodiment of the present application takes into account the following three situations: (1) When it is detected that the second target connection point is associated with the FCB load side (such as associated with FCBa1), the second target connection point is determined as the second target load connection point, that is, the connection point ID corresponding to the second target connection point is directly assigned to the JNODE field of FCBa1, and the topological device table is updated; (2) When the second target connection point is associated with SWLL, based on the preset SWLL connection point splicing rules, determine the second target load connection point and the second target power connection point; (3) when it is detected that the second target connection point is associated with other reference devices other than FCB (such as FCBa1) and SWLL, determine the load connection point corresponding to the reference device as the second target load connection point, and determine the power connection point corresponding to the reference device as the second target power connection point, that is, determine the load connection point ID and power connection point ID of the reference device, directly assign the load connection point ID of the reference device to the JNODE field of FCBa1 in the topology device table, and directly assign the power connection point ID of the reference device to the INODE field of FCBa1 in the topology device table, and update the topology device table. In this way, the operation of updating the connection point association device table and the topology device table based on the connection point identifier corresponding to the second target load connection point and the second target power connection point is completed, and then the distribution line topology to be spliced ​​is constructed.

[0126] Specifically, after the distribution line topology is constructed, the target splicing point is spliced ​​with the SWLL. The target splicing point is the splicing point of the distribution line topology to be spliced ​​constructed in the above embodiment. The splicing point belongs to the single-line diagram, and the distribution line topologies with associated relationships are spliced ​​with each other through SWLL to obtain the full network topology of the target distribution network. Specifically, in the process of splicing the target splicing point with the SWLL, it is necessary to compare whether the ID of the target splicing point is consistent with the ID of the SWLL in the topology device table. This embodiment considers the following three situations: (1) When the identification fields corresponding to the load connection point and the power connection point of the SWLL in the topology device table are both empty, the splicing point identification corresponding to the target splicing point is assigned to the identification field of the power connection point corresponding to the SWLL in the topology device table, that is, the connection point ID corresponding to the target splicing point is assigned to the INODE field of the SWLL in the topology device table; (2) When the load connection point and the power connection point corresponding to the SWLL in the topology device table are both empty, the splicing point identification corresponding to the target splicing point is assigned to the identification field of the power connection point corresponding to the SWLL in the topology device table, that is, the connection point ID corresponding to the target splicing point is assigned to the INODE field of the SWLL in the topology device table; (3) When the load connection point and the power connection point corresponding to the SWLL in the topology device table are both empty, the target splicing point is assigned to the INODE field of the SWLL in the topology device table; (4) When the load connection point and the power connection point corresponding to the SWLL in the topology device table are both empty, the target splicing point is assigned to the INODE field of the SWLL in the topology device table; (5) When the load connection point and the power connection point corresponding to the SWLL in the topology device table are both empty, If one of the corresponding identification fields is empty, determine whether the reference splicing point corresponding to the splicing point identification whose identification field is not empty belongs to the single-line diagram. The reference splicing point is the connection point whose identification field corresponding to the SWLL currently stored in the topology device table is not empty. Determine whether the connection point ID corresponding to the reference splicing point is generated by this modeling diagram). When the reference splicing point belongs to the single-line diagram (that is, the connection point ID corresponding to the reference splicing point is generated by this modeling diagram, and the ID of the target splicing point is consistent with the ID of the SWLL in the topology device table), replace the splicing point identification corresponding to the reference splicing point with the splicing point identification corresponding to the target splicing point. When the reference splicing point does not belong to the single-line diagram (that is, the connection point ID corresponding to the reference splicing point is generated by this modeling diagram, and the ID of the target splicing point is consistent with the ID of the SWLL in the topology device table), replace the splicing point identification corresponding to the target splicing point with the splicing point identification corresponding to the reference splicing point. (3) When the identification fields corresponding to the load connection point and the power connection point of SWLL in the topology device table are not empty, randomly select the first reference splicing point from the load connection point and the power connection point (that is, randomly select an ID from the two IDs corresponding to the INODE field and the JNODE field of SWLL in the topology device table as the ID of the first reference splicing point), determine Whether the first reference splicing point belongs to the single-line diagram. When the first reference splicing point belongs to the single-line diagram, it means that the ID of the target splicing point is consistent with the ID of the first reference splicing point. The splicing point identifier corresponding to the target splicing point is replaced with the splicing point identifier corresponding to the first reference splicing point. When the first reference splicing point does not belong to the single-line diagram, it means that the ID of the target splicing point is inconsistent with the ID of the first reference splicing point. Another second reference splicing point is selected from the load connection point and the power connection point to determine whether the second reference splicing point belongs to the single-line diagram. When the second reference splicing point belongs to the single-line diagram, the splicing point identifier corresponding to the target splicing point is replaced with the splicing point identifier corresponding to the second reference splicing point.When both the first reference splicing point and the second reference splicing point do not belong to the single-line diagram, it means that the two IDs corresponding to the INODE field and the JNODE field of SWLL in the topology device table are not generated by this modeling diagram, and the tie switch SWLL is switched from other modeling diagrams. The identification fields of all connection points corresponding to SWLL in the topology device table are emptied, that is, the INODE field and the JNODE field corresponding to SWLL in the topology device table are emptied, in order to disconnect the original topology, and assign the splicing point identification corresponding to the target splicing point to the identification field of the power connection point corresponding to SWLL in the topology device table. ;

[0127] It can be understood that the step of constructing the distribution line topology in this embodiment, as well as the step of splicing related distribution line topologies through SWLL to generate the whole network topology, can be achieved in different situations (including consistency and inconsistency between graphic data and preset data table data), which can maximize the success rate of construction of the distribution line topology and avoid errors in the subsequent construction of the whole network topology.

[0128] In addition, in some embodiments, the single-line diagram includes at least a first single-line diagram and a second single-line diagram, and the first single-line diagram and the second single-line diagram have an association relationship. The method for generating the full network topology of the distribution network of the embodiment of the present application also includes but is not limited to the following steps:

[0129] Step S51, entering the first device identifier corresponding to the SWLL in the first single-line diagram into a preset splicing device lock table;

[0130] Step S52, executing a topology generation operation of a first distribution line topology corresponding to the first single line diagram based on the splicing device lock table, and determining an execution state of the topology generation operation;

[0131] Step S53, when the execution status representation corresponding to the first single line diagram is completed, the first device identifier in the splicing device lock table is deleted, the second device identifier is entered into the splicing device lock table, and a topology generation operation of the second distribution line topology is performed based on the splicing device lock table;

[0132] or,

[0133] Step S54: when the execution status representation corresponding to the first single-line diagram is being executed, the operation of entering the second device identifier into the splicing device lock table is not performed.

[0134] In addition, in some embodiments, the single-line diagram includes at least a first single-line diagram and a second single-line diagram, and there is no association relationship between the first single-line diagram and the second single-line diagram. The method for generating the full network topology of the distribution network of the embodiment of the present application also includes but is not limited to the following steps:

[0135] Entering a first device identifier corresponding to the SWLL in the first single-line diagram and a second device identifier corresponding to the SWLL in the second single-line diagram into a preset splicing device lock table;

[0136] A first distribution line topology corresponding to the first single-line diagram and a second distribution line topology corresponding to the second single-line diagram are generated in parallel based on the splicing device lock table.

[0137] It should be noted that this embodiment does not limit the number of specific single-line diagrams, and there may be two or more single-line diagrams, depending on the actual situation of the target distribution network.

[0138] Specifically, the splicing device lock table of this embodiment may include a connection device identifier, a modeling diagram identifier, and a data entry timestamp.

[0139] It can be understood that in this embodiment, when there are currently a first single-line diagram and a second single-line diagram with a topology to be generated, it is necessary to first detect the association relationship between the first single-line diagram and the second single-line diagram, and the two single-line diagrams with an associated relationship need to be mutually exclusive through the splicing device lock table, that is, the topology generation operation cannot be performed simultaneously. The specific steps are: entering the first device identifier corresponding to the SWLL in the first single-line diagram into the preset splicing device lock table; executing the topology generation operation of the first distribution line topology corresponding to the first single-line diagram based on the splicing device lock table, and determining the execution status of the topology generation operation; when the execution status representation corresponding to the first single-line diagram is executed, deleting the first device identifier in the splicing device lock table, releasing the splicing device lock, entering the second device identifier into the splicing device lock table, and executing the topology generation operation of the second distribution line topology based on the splicing device lock table; when the execution status representation corresponding to the first single-line diagram is in execution, the operation of entering the second device identifier into the splicing device lock table is not executed, so as to achieve the purpose of mutual exclusion.

[0140] In addition, for the first single-line diagram and the second single-line diagram that are not associated, the first device identifier corresponding to the SWLL in the first single-line diagram and the second device identifier corresponding to the SWLL in the second single-line diagram are entered into the preset splicing device lock table; based on the splicing device lock table, the first distribution line topology corresponding to the first single-line diagram and the second distribution line topology corresponding to the second single-line diagram are generated in parallel. That is to say, by importing a single-line diagram through a thread, the splicing device lock table simultaneously stores the device identifiers of the SWLLs corresponding to the two single-line diagrams that are not associated, so that the first single-line diagram and the second single-line diagram perform topology generation operations in parallel, and generate the full network topology of the target distribution network in parallel, thereby improving the generation efficiency of the full network topology.

[0141] In addition, the method of this embodiment also includes clearing the connection points of the splicing equipment according to the identification of the modeling diagram when the distribution line is deleted.
