Description

Technical Field

[0001] This invention proposes a distribution network ticketing method and system based on power supply sequence arrangement and logical power supply partitioning, which relates to the field of distribution network operation and maintenance automation technology. Background Technology

[0002] Currently, existing technologies related to switching operation decisions in distribution networks include topology modeling, graph traversal algorithms, equipment coding, and switching operation ticket rule bases.

[0003] The current technology for automatically generating command tickets for power supply and phase verification, as well as automatic transfer switching tests in substations, generally relies on a single-layer general breadth-first traversal algorithm modeling from the substation feeder bay to the end of the distribution network line, command ticketing rule matching, and standard command template filling into the ticket. The overall technical architecture and implementation method are as follows:

[0004] 1. Topology modeling and device grouping

[0005] Currently, mainstream systems build their topology models based on equipment such as station busbars (Bus I and Bus II), switches, disconnectors, and drop-out fuses in the DMS single-line diagram. Equipment ownership is determined entirely by the equipment's topology connection to upstream substation switches. After modeling, it is only used for equipment status display, topology connectivity verification, global traversal driven by power supply points, and coloring (equipment energized status).

[0006] 2. Topology Identification and Data Storage

[0007] Existing technologies store and retrieve station topology connections, current flow direction, and operation ticket text separately as three independent fields or data tables. Topology connections are recorded using equipment numbers, current flow direction is marked by independent status bits, and operation ticket text is generated by splicing together preset templates. The correlation between database tables is weak, there is a lot of redundant information, and each time an instruction is generated, multiple rounds of data matching and format conversion are required.

[0008] 3. The sub-functional modules are independent of each other.

[0009] In existing technology, the initial state setting confirmation, phase verification, and backup automatic start-up test are three independent operations belonging to different functional modules. The same device may require operation in different functional modules, making it difficult to guarantee the continuous and correct state of the same device's operation instructions across different modules. The system relies on external rule and template libraries to actively search and match to generate operation instructions. When the station topology is complex and nodes are intertwined and chaotic, the system cannot reasonably arrange the order of station operations, frequently resulting in disordered instruction sequences and ticketing failures, requiring manual arrangement of operation steps.

[0010] 4. Operation sequence and safety precautions

[0011] Traditional solutions lack native operational sequence constraints, relying solely on post-operation logic verification and manual monitoring to prevent misoperation. Multiple independent functional modules generate operation commands for the same device, making it difficult to guarantee continuous changes in the operational status of adjacent commands. Simultaneous phase verification and automatic transfer switch tests at upstream stations can generate electrical disturbances that can easily cause malfunctions in the automatic transfer switch at downstream stations, posing significant safety hazards.

[0012] Instruction Ticket Generation Rules

[0013] Existing technologies rely on external, massive expert rule bases, have few built-in constraint logics, have bloated system architectures, and are difficult to deploy in a lightweight manner. Summary of the Invention

[0014] In view of this, and to fill the gaps and deficiencies in the existing technology, this invention proposes a distribution network ticketing method and system based on power supply sequence arrangement and logical power supply partitioning. This invention is used to solve problems that existing technologies cannot address.

[0015] This invention proposes a distribution network ticketing method and system based on power supply sequence arrangement and logical power supply partitioning, including the following:

[0016] According to a first aspect of the present invention, the present invention proposes a distribution network ticketing method based on power supply sequence arrangement and logical power supply partitioning. The method is characterized in that each electrical substation in the distribution network is defined as an independent power receiving unit, and the entire power transmission operation process is modeled as a process in which a series of power receiving units are activated one by one and execute internal operation instructions after the synchronization condition that all incoming lines are energized is met. For a single-incoming-line power receiving unit, its incoming line is activated as soon as it is ready. For a dual-incoming-line power receiving unit, it must wait for all incoming lines on both sides to be ready before it is activated; if they are not ready, its traversal order is automatically delayed until all incoming lines have appeared.

[0017] Furthermore, the method also includes the following:

[0018] Step S1: Perform topology data parsing and power receiving unit modeling; including obtaining raw data from the DMS system and abstracting the physical power grid into a power receiving unit topology model;

[0019] Step S2: Execute incoming line readiness determination and synchronous waiting trigger instruction, including defining each power receiving unit as a logical entity that must wait for all its incoming lines to be accessed before it can be activated and perform subsequent operations;

[0020] Step S3: Perform logical power supply partitioning and dynamic data aggregation, including using a logical power supply partitioning dynamic aggregation method based on power tag transmission;

[0021] Step S4: Perform integrated semantic tag encoding and ordered restricted interlocking verification, including encoding the topology analysis results into a unified semantic tag format, and orderly interlocking and releasing the power receiving unit;

[0022] Step S5: Execute multi-service security ticketing, instruction item verification and operation ticket output, including initial status confirmation and electrical isolation preprocessing, automatically generate complete equipment initial status confirmation, power supply, phase verification, and backup automatic switching test operation instruction tickets, and automatically complete the legality of the status within the instruction item and the global equipment status continuity verification.

[0023] Further, step S1 includes the following:

[0024] In step S1, the inputs required for topology data parsing and power receiving unit modeling include: incoming and outgoing line datasets in the DMS system, datasets of other equipment besides the switch, and service tag set;

[0025] The output required for topology data parsing and power receiving unit modeling includes: power receiving unit type, service tag, directed graph, and queue to be traversed;

[0026] Step S1 also includes the following:

[0027] Step S11: Data collection is performed, including collecting data on all electrical equipment in the target power supply area through the distribution automation DMS server and constructing a unified input dataset for the algorithm; the dataset includes incoming and outgoing line datasets, datasets of other equipment besides switches, and a set of business tags;

[0028] Step S12: Define each electrical station as a power receiving unit, including calling the built-in station type determination function to automatically classify four types of power receiving units based on the busbar number, whether there is a bus branch, and the bus branch label;

[0029] Step S13: Construct a standardized topology adjacency list based on the electrical connection relationship of the equipment, and represent the distribution network topology as a directed graph, which includes a set of power receiving unit nodes and a set of directed edges, wherein the direction of the directed edges is from the power source side to the load side; then initialize the global queue of power receiving units to be traversed, and write all power points in the region into the queue.

[0030] Further, step S2 includes the following:

[0031] In step S2, the input required for executing the incoming line readiness determination and synchronization wait trigger command includes:

[0032] Power receiving unit type, directed graph, queue to be traversed;

[0033] In step S2, the output of the incoming line readiness determination and synchronization wait trigger instruction includes:

[0034] List of activated power receiving units and logical power supply zones.

[0035] Step S2 also includes the following:

[0036] Step S21: Initialize the global set of accessed lines; initialize logical power supply partitions, which are used in step S3 to collect incoming and outgoing lines from different power sources. The definition of a logical power supply partition is: a logical set consisting of all power receiving units powered by the same power source. The partition does not have a preset physical boundary and is determined entirely by the dynamic transmission result of the power tag.

[0037] Step S22: Line Readiness Determination: Take out (without replacement) the first power receiving unit to be processed in the global queue of power receiving units to be traversed, call the built-in line readiness determination operator, and perform full line readiness synchronous determination.

[0038] Step S23: Branch processing, including the following:

[0039] If the value of the incoming line ready determination operator is True if and only if all incoming line identifiers of the power receiving unit already exist in the set of visited lines, then the power receiving unit is marked as activated and sent to step S3 for subsequent processing.

[0040] If the power receiving unit does not meet the condition that all incoming line identifiers already exist in the set of visited lines, and the value of the incoming line ready determination operator is False, then the power receiving unit is moved to the second position of the queue of the set of visited lines for delayed processing, and the process jumps to step S22 to read the next power receiving unit.

[0041] Step S24: Iteration: Repeat steps S22 to S23 until all powered units in the global queue of powered units to be traversed are activated.

[0042] Further, step S3 includes the following:

[0043] In step S3, the input required for logical power supply partitioning and dynamic data aggregation includes:

[0044] Power receiving unit and logical power supply zone activated;

[0045] In step S3, the output content of logical power supply partitioning and dynamic data aggregation includes:

[0046] Bind the power receiving unit's incoming and outgoing lines to the corresponding incoming and outgoing line associated datasets based on the partition identifier;

[0047] Step S3 also includes the following:

[0048] Step S31: For activated power receiving units, invoke the partition affiliation mapping operator; the operation rules of this operator are strictly defined by the partition affiliation function:

[0049] Step S32: Status recording, including writing the currently completed incoming and outgoing lines into two sets of logical power supply partition sets, and binding the corresponding logical power supply partition identifier to each bus segment and each incoming and outgoing line of the power receiving unit.

[0050] Further, step S4 includes the following:

[0051] In step S4, the input required for integrated semantic label encoding and ordered restricted locking verification includes:

[0052] Bind the power receiving unit's incoming and outgoing lines to the corresponding incoming and outgoing line associated datasets based on the partition identifier;

[0053] In step S4, the output of the integrated semantic tag encoding and ordered restricted locking check includes:

[0054] The sequence of power receiving units that have been unlocked and released, and the integrated semantic tag set;

[0055] Step S4 also includes the following:

[0056] Step S41: Generate semantic tag encoding, including generating integrated semantic tags using a four-segment fixed structure; wherein the integrated semantic tags include: upstream station, upstream outgoing line, downstream station, and downstream incoming line;

[0057] Step S42: Orderly power receiving interlocking model. Calculate the set of interlocking stations to be released after all upstream stations have completed all operations. If upstream stations have not completed all operations, the interlocking remains; if upstream stations have completed all operations, the interlocking of all downstream stations directly connected to the outgoing lines of the upstream station is released, thus realizing the orderly power receiving interlocking and unlocking functions.

[0058] Further, step S5 includes the following:

[0059] In step S5, the input required for multi-service security ticketing and operation tickets includes:

[0060] The sequence of power receiving units that release the interlock and allow passage, the integrated semantic tag, and the service tag input by module one;

[0061] In step S5, the output content of the multi-service security ticket and operation ticket includes:

[0062] A complete switching operation instruction ticket;

[0063] Step S51: Initial state confirmation and electrical isolation preprocessing, call the built-in electrical isolation operator; if the downstream power receiving unit carries a phase return mark or a standby automatic transfer mark, the operator outputs a control command to set the initial state of the corresponding outgoing line of this level to hot standby, construct an electrical isolation interval, and isolate the upstream test disturbance from being transmitted downstream.

[0064] Step S52: Service tag identification and instruction generation. Combining the initial state confirmation and electrical isolation preprocessing functions in step S51, the initial state of the equipment is confirmed, and the corresponding instruction ticket is generated based on the phase verification and standby automatic transfer tags.

[0065] Step S53: Construct a single instruction validity check function. If the initial state and the target state are different within a single instruction item, it is valid; otherwise, it is invalid. This is used as a single instruction item check function.

[0066] Step S54: Construct a global continuity determination function and a global continuity determination function for the same device instruction ticket. For the instruction sequence of the same device with the same instruction ticket, starting from the first instruction, check the state continuity of adjacent instructions one by one, and thus realize the global device instruction continuity determination and verification.

[0067] Step S55: Command Integration and Output: Integrate all operation commands according to the upstream priority sequence, format and generate standardized distribution network operation tickets that can be directly executed on site, and output them to the DMS dispatch workstation.

[0068] According to a second aspect of the present invention, the present invention proposes a distribution network ticketing system based on power supply sequence arrangement and logical power supply partitioning, for executing a distribution network ticketing method based on power supply sequence arrangement and logical power supply partitioning as described in any one of the present invention, characterized in that it includes the following:

[0069] Topology data parsing and power receiving unit modeling module; used to obtain raw data from the DMS system and abstract the physical power grid into a power receiving unit topology model;

[0070] The incoming line readiness determination and synchronous waiting trigger instruction module is used to define each power receiving unit as a logical entity that must wait for all its incoming lines to be accessed before it can be activated and perform subsequent operations.

[0071] The logical power supply partitioning and dynamic data aggregation module is used to adopt the logical power supply partitioning dynamic aggregation method based on power tag transmission;

[0072] An integrated semantic tag encoding and temporal traversal module includes encoding topology analysis results into a unified semantic tag format;

[0073] The orderly power receiving interlocking model includes a method that, by identifying that all operations have been completed in the upstream stations of the station, releases the interlocking of the station and allows the station to perform its operational functions.

[0074] The multi-service security ticketing, instruction item verification and operation ticket output module includes automatically generating complete power supply, phase verification and backup automatic transfer test operation instruction tickets based on the output of the preceding module;

[0075] A method for constructing a single instruction validity verification function model to implement the verification function that the initial state and the target state must be different within a single instruction item;

[0076] A global continuity determination function and a full-ticket global continuity determination function model for instruction tickets of the same device are constructed to implement a method for verifying that the target state of the previous instruction of each pair of adjacent instructions of the same device with the same instruction ticket must be the same as the initial state of the next instruction.

[0077] According to a third aspect of the present invention, the present invention proposes a distribution network ticketing system based on power supply sequence arrangement and logical power supply partitioning, comprising an electronic device, wherein the electronic device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that, when the processor executes the computer program, it implements a distribution network ticketing method based on power supply sequence arrangement and logical power supply partitioning as described in any one of the present invention.

[0078] According to a fourth aspect of the present invention, the present invention proposes a distribution network ticketing system based on power supply sequence arrangement and logical power supply partitioning, comprising a computer-readable storage medium storing a computer program, characterized in that, when the computer program is executed by a processor, it implements a distribution network ticketing method based on power supply sequence arrangement and logical power supply partitioning as described in any one of the present invention.

[0079] The present invention has the following advantages:

[0080] 1. This solves the problem that traditional solutions, which rely on the topological connections between lines, stations, and equipment, cannot effectively convert the topological relationships into the power supply sequence for multi-branch, multi-connection (frequent branch point) line structures.

[0081] 2. Solve the problems of separate storage of multiple fields such as topology, flow direction, and operation text, resulting in data redundancy, cumbersome conversion, and complex links.

[0082] 3. Resolve the issues of fragmented functional modules for initial status confirmation, phase verification, and backup automatic start-up test of station equipment, which prevent integrated automatic ticket generation, ticket issuance failure under complex topologies, disordered instruction sequence, and inability to connect the status of repeated operations on the same equipment.

[0083] 4. To address the problem of insufficient safety in the operation of electrical equipment due to the lack of native operation sequence constraints, which can easily lead to malfunctions of downstream automatic switching during upstream testing operations.

[0084] Furthermore, the present invention has the following advantages

[0085] The topology-driven logic differs: Existing technologies model based on topological connections. However, when faced with complex electrical connection topologies (multi-ring, multi-level series), existing technologies struggle to organize and sequence power transmission operations for cross-line interconnection stations, easily leading to errors, omissions, or conflicting instructions, and heavily relying on manual intervention for correction. This application proposes to eliminate the limitations of equipment topology connections, treating the station as a single "power receiving unit." The power transmission operation sequence is transformed into a hierarchical arrangement of station connections starting from the power source point, eliminating the need to process complex topology connection node information to arrive at a clear power transmission operation sequence.

[0086] The power supply logic for dual-power substations differs: Existing technologies require phase verification and automatic transfer switching tests during the startup and power supply process of high-voltage dual-power substations. Complex preset rules are needed to ensure the synchronous arrival of power from both sides at the substation before corresponding commands can be generated. This proposal treats the substation as a "power receiving unit." During startup and power supply, if all incoming lines to a substation are "energized," its "command generation module" is activated to generate operation commands. If any incoming lines to a substation are not "energized," activation of that substation is delayed, prioritizing activation of substations with all incoming lines "energized." Once the "command generation module" of the higher-level substation has completed its task, activation of the lower-level substation is permitted.

[0087] The data retrieval methods differ: Existing technologies store station topology connections, current flow direction, and operation ticket text in multiple independent database fields, resulting in information isolation. Generating instruction tickets requires repeated data retrieval, matching, and format conversion, leading to data redundancy and a lack of unified association identifiers. This application proposes a semantic tag composed of information from upstream and downstream incoming and outgoing line equipment. A single tag integrates topology connections, current flow direction, and instruction generation information text, allowing a single data set to be used throughout the entire process of topology determination, equipment aggregation, and instruction ticket issuance. This simplifies the data chain and improves data reuse and consistency.

[0088] The ticketing mechanism and business linkage capabilities differ: In existing technologies, the initial state confirmation, phase verification, and automatic transfer switch (ATS) tests of each bay's equipment in the station are independent business modules, each generating instruction tickets based on its own rule base and templates. The linkage between modules is poor, and it cannot guarantee the continuity of instruction results executed by each independent functional module on the same equipment. Phase verification and ATS tests require multiple power outages, power restorations, loop closing, and loop unclosing operations on the same area. When the station's topology is complex and lines are intertwined, the system cannot correctly sort out the order of operations, requiring manual intervention to adjust the steps. This application proposes a deep integration of topology traversal and instruction ticket generation. During the step-by-step power restoration process, station markers (phase verification, ATS, constant switching) are identified in real time, automatically triggering the corresponding initial state, phase verification, and ATS test instruction ticket items for each bay's equipment. This achieves integrated generation of multiple services, ensuring continuous changes in instructions generated by different functions performing multiple operations on the same equipment.

[0089] The operational sequence and safety prevention principles differ: Existing technologies rely on preset rules or manual programming, with safety protection measures concentrated on passive prevention such as post-event logic verification. Electrical disturbances generated during phase verification and automatic transfer switching tests at the upper-level station can easily lead to pre-phase verification before loop-connected power supply and malfunctions of downstream automatic transfer switches, posing safety hazards. This application proposes utilizing a power supply sequence of "power source - upper-level station - lower-level station," generating operational instructions for each level of station. Upon activating a station, it first checks whether the lower-level station requires phase verification and automatic transfer switching tests. The connection lines of the corresponding lower-level stations requiring these tests are placed in the initial state of hot standby (electrically isolating the upper and lower-level stations to avoid power outages during the phase verification and automatic transfer switching tests at the current station, which could cause malfunctions in the lower-level automatic transfer switches). The standby bay is placed in line maintenance mode, the indoor transformer in the station is placed in no-load operation mode, and the remaining lines are placed in... The system generates corresponding on-site confirmation items based on the operational status, and gradually generates relevant operations for phase verification and automatic transfer switching tests at the current station level based on the initial state. After the higher-level station level completes all phase verification and automatic transfer switching tests, the system executes the lower-level power supply and phase verification and automatic transfer switching tests according to the traversal sequence. This proactive process prevents errors and avoids the problem of inconsistent states when the same equipment repeatedly generates operation items. It also mitigates risks such as power supply loops without phase verification, electrical disturbances caused by phase verification and automatic transfer switching tests at the higher-level station level, and malfunctions of automatic transfer switching at the lower-level station level, thereby improving the compliance and safety of electrical operations.

[0090] The overall system architecture and operational complexity differ: Existing intelligent ticketing systems heavily rely on expert rule bases and instruction templates, resulting in a complex and cumbersome architecture. Later rule updates and template maintenance are labor-intensive, and lightweight deployment is difficult. For the electrical substation startup and power supply, which involves confirming the initial state of each device at each level, phase verification for both same and different sources, and automatic transfer switching tests, multiple sets of identical incoming and outgoing line switches need to be repeatedly opened and closed. There are no corresponding control rules, and the same device may exhibit inconsistent states during repeated operation item generation. Without phase verification and loop closure, phase verification and automatic transfer switching tests at higher-level substations can cause electrical disturbances, posing a risk of malfunctioning automatic transfer switches at lower-level substations. The core logic of this application is topology traversal and aggregation based on power supply topology connections. It does not rely on external rule bases, has a simpler architecture, and reduces reliance on later operational and maintenance costs and iteration costs. Attached Figure Description

[0100] like Figures 1 to 6 As shown, this invention proposes a distribution network ticketing method and system based on power supply sequence arrangement and logical power supply partitioning, characterized by including the following:

[0101] According to a first aspect of the present invention, the present invention proposes a distribution network ticketing method based on power supply sequence arrangement and logical power supply partitioning. The method is characterized in that each electrical substation in the distribution network is defined as an independent power receiving unit, and the entire power transmission operation process is modeled as a process in which a series of power receiving units are activated one by one and execute internal operation instructions after the synchronization condition that all incoming lines are energized is met. For a single-incoming-line power receiving unit, its incoming line is activated as soon as it is ready. For a dual-incoming-line power receiving unit, it must wait for all incoming lines on both sides to be ready before it is activated; if they are not ready, its traversal order is automatically delayed until all incoming lines have appeared.

[0102] Furthermore, the method also includes the following:

[0103] Step S1: Perform topology data parsing and power receiving unit modeling; including obtaining raw data from the DMS system and abstracting the physical power grid into a power receiving unit topology model;

[0104] Step S2: Execute incoming line readiness determination and synchronous waiting trigger instruction, including defining each power receiving unit as a logical entity that must wait for all its incoming lines to be accessed before it can be activated and perform subsequent operations;

[0105] Step S3: Perform logical power supply partitioning and dynamic data aggregation, including using a logical power supply partitioning dynamic aggregation method based on power tag transmission;

[0106] Step S4: Perform integrated semantic tag encoding and ordered restricted interlocking verification, including encoding the topology analysis results into a unified semantic tag format and arranging the processing order of the power receiving units according to the electrical safety timing sequence;

[0107] Step S5: Perform multi-service security ticketing, instruction item verification and operation ticket output, including automatically generating complete power supply, phase verification and backup automatic transfer test operation instruction tickets based on the output of the preceding modules.

[0108] Further, step S1 includes the following:

[0109] Step S1: Topology data parsing and power receiving unit modeling:

[0110] Step Description: Collect basic information and electrical connections of all electrical substations, busbars, and incoming / outgoing lines within the power supply area to construct a complete distribution network topology model. This model can clearly represent the physical connections between equipment and the power transmission path, and supports manual labeling of substations with phase verification marks, automatic transfer switch marks, and busbar / branch connection point marks.

[0111] Technical Issue: In existing technologies, while topology models can identify device connection relationships, they cannot directly drive the arrangement of operation sequences. Technical Benefit: The constructed topology model provides a data foundation for subsequent power-driven traversal and station type determination, and presets the trigger conditions for instruction generation.

[0112] In one embodiment of the present invention, step S1 further includes the following:

[0113] Step S1 is responsible for obtaining raw data from the DMS system and abstracting the physical power grid into a power receiving unit topology model.

[0114] Input: Incoming and outgoing line datasets from the DMS system, datasets of other devices besides switches, and service tag set.

[0115] Step S11: Data Acquisition: Collect data on all electrical equipment in the target power supply area through the distribution automation DMS server, and construct a unified input dataset for the algorithm.

[0116] .

[0117] in:

[0118] For incoming and outgoing line datasets, store the station name, switch bay name, outgoing line number identifier (91× / 92×), connection node number, and store the four-state parameters of the switch (operating / hot standby / cold standby / maintenance);

[0119] This is the dataset for all equipment other than the switch, including bus PTs, distribution transformers, and station service transformers.

[0120] This is a set of business tags, containing nuclear phase tags. Self-deployment marker denominator constant marking .

[0121] Step S12: Power receiving unit type determination: Define each electrical station as a "power receiving unit" and call the built-in station type determination function. Based on the busbar number and the presence or absence of a bus branch, the power receiving unit is automatically classified into four categories. The decision logic of this function is strictly defined by the following piecewise function:

[0122] Let the configuration parameters of the bus branch switch be M (M=1 indicates that there is a bus branch, M=0 indicates that there is no bus branch), the constant branch mark of the bus branch is D (D=1 indicates that there is a constant branch mark, D=0 indicates that there is no mark), the existence of the 91× numbered line is A (A=1 indicates that it exists, A=0 indicates that it does not exist), and the existence of the 92× numbered line is B (B=1 indicates that it exists, B=0 indicates that it does not exist).

[0123] but function output Determined by the following formula:

[0124] ;

[0125] The meaning of the judgment rule is as follows:

[0126] Table 1. Step S1 Judgment Rule 1

[0127]

[0128] Table 2 Step S1 Judgment Rule 2

[0129]

[0130] Step S13: Topology Adjacency List Construction: Construct a standardized topology adjacency list based on the electrical connection relationships of the devices, representing the distribution network topology as a directed graph G=(V, E), where V is the set of power receiving unit nodes and E is the set of directed edges, with the direction of the directed edges pointing from the power source to the load side. Initialize the global queue of power receiving units to be traversed. Write all power points in the area into the queue.

[0131] Output: Carries the type of power receiving unit Business tags A directed graph G=(V,E) and a queue to be traversed.

[0132] The process of step S1 is as follows: Figure 2 As shown.

[0133] Further, step S2 includes the following:

[0134] Step S2: Incoming line readiness determination and synchronization wait for trigger command:

[0135] Step Description: Add all power points to the "to be traversed sequence," and extract the first element of each sequence. Perform a breadth-first topology traversal along the downstream direction of the power supply. During the traversal, perform the following operations:

[0136] Station building type determination: Based on the station building's incoming and outgoing line operation number (91× or 92×) and the busbar / branch label status, the system automatically determines whether the station building is of one of four types: "single incoming line single busbar", "single incoming line double busbar", "double incoming line with busbar / branch double busbar", and "double incoming line without busbar / branch double busbar".

[0137] Incoming line readiness judgment: For a station with two incoming lines and two busbars, search the "visited line sequence" of the two logical power supply zones. If both incoming lines of the station have appeared, the aggregation operation is performed; if only one has appeared, the station is moved one position to the right in the "to be traversed sequence" and the aggregation operation is triggered after the incoming lines of the other busbar are traversed.

[0138] Logical power supply zone aggregation: Store the traversed lines into the "visited line sequence", and store the aggregation results in the corresponding logical power supply zone according to the station traversal order.

[0139] Technical Problem: Existing technology cannot automatically handle the problem of inconsistent arrival times of incoming lines on both sides of a dual-power station, leading to disordered order. Technical Effect: Through the "incoming line readiness judgment" and "delayed traversal" mechanisms, the algorithm automatically adapts to complex multi-connection line structures, ensuring that the station is processed only after all incoming lines are ready, fundamentally avoiding order errors.

[0140] In one embodiment of the present invention, step S2 further includes the following:

[0141] In step S2, the input required for executing the incoming line readiness determination and synchronization wait trigger command includes:

[0142] Power receiving unit type, directed graph, queue to be traversed;

[0143] In step S2, the output of the incoming line readiness determination and synchronization wait trigger instruction includes:

[0144] List of activated power receiving units, two sets of logical power supply partitions , .

[0145] Step S21: Initialization: Initialize the global set of accessed lines. It is initially an empty set.

[0146] Initialization: Initialize two sets of logical power supply partitions. , These are used to aggregate incoming and outgoing lines from different power sources. A logical power supply zone is defined as: a logical set of all powered units supplied by the same power source. The zones do not have pre-defined physical boundaries; they are entirely determined by the dynamic transmission of power tags.

[0147] Step S22: Incoming line ready determination: Read The first power receiving unit to be processed Call the built-in incoming line ready determination operator The "full-line ready synchronization judgment" is executed. The judgment logic of this operator is strictly defined by the following mathematical expression:

[0148] Let the set of all incoming line identifiers of the power receiving unit U be:

[0149] ;

[0150] in For the station building's incoming line, k is the total number of incoming lines for this power receiving unit (k=1 or k=2). Then... The operator's output is:

[0151] ;

[0152] The algorithmic meaning of this formula is: if and only if the power receiving unit All incoming line identifiers are already present in the visited line set. If the condition is met, the operator returns True; otherwise, it returns False.

[0153] Step S23: Branch processing:

[0154] like ( , ) = False: Move the power receiving unit to The second position in the queue is processed later; jump to step S22 of this module to read the next power receiving unit.

[0155] like ( , ) = True: Mark the powered unit as "activated" and send it to Module 3 for further processing.

[0156] regardless ( , Regardless of the outcome, this step will affect the currently accessed [data / data / etc.]. join in .

[0157] Step S24: Iteration: Repeat steps S22 to S23 until... All powered units are activated.

[0158] Output: A list of activated power receiving units and the corresponding set of accessed lines. Logical power supply partitioning.

[0159] Technical significance: The mathematical expression of the above synchronization mechanism strictly defines the judgment criteria of "full incoming line readiness", which ensures the safety premise of phase verification operation in multi-power supply interconnection station from the algorithm bottom layer. The phase verification and backup automatic transfer test of dual incoming line power receiving unit can only be performed after both power supplies have arrived at the unit, without relying on external rule verification.

[0160] The process of step S2 is as follows: Figure 3 As shown.

[0161] Further, step S3 includes the following:

[0162] Step S3: Logical power supply partitioning and dynamic data aggregation:

[0163] Step Description: The incoming lines to lower-level stations are dynamically identified via outgoing line tags from the upper-level station, along with the logical power supply zone set to which the lines belonging to the same busbar segment as these incoming lines belong. , Lines without incoming busbars and single-incoming-line double-busbars are assigned to another section of the section with incoming busbars.

[0164] Technical issue: By manually defining logical power supply zones and sorting the electrical substations one by one in step S2, the connection correspondence between the incoming and outgoing lines of each upper and lower level group of the substation can be clearly defined, and in step S4, integrated semantic tags are used to record and store the data.

[0165] In one embodiment of the present invention, step S3 further includes the following:

[0166] Instead of the traditional approach of fixedly dividing busbars according to physical segments (Bus I, Bus II), a dynamic aggregation method based on power supply tag transmission for logical power supply partitioning is adopted.

[0167] Input: The activated power receiving unit output from step S2, and the two sets of logical power supply partitions. , .

[0168] Processing steps:

[0169] Step S31: Partitioning and aggregation: For activated power receiving units Call the partition attribution mapping operator Map( , , The operational rules of this operator are strictly defined by the following piecewise functions:

[0170] Type of power receiving unit;

[0171] L( () represents the set of all incoming and outgoing lines;

[0172] ( )for The incoming line set;

[0173] ( (incoming line) The logical power supply zone to which the outgoing line from the superior station belongs.

[0174] ( )∈{ , };

[0175] b( ) is the incoming line The busbar segment in question;

[0176] For another busbar;

[0177] (b) represents all incoming and outgoing lines of busbar segment b;

[0178] , For two logical power supply partition sets;

[0179] For another logical partition (if , = ;if , = )

[0180] ( () represents the set of outgoing lines from another busbar;

[0181] The aggregation rule for the Map operator is:

[0182] ;

[0183] Step S32: Status Recording: Write the currently completed inbound and outbound lines to the current collection. , Bind the corresponding logical power supply zone identifier to the power receiving unit.

[0184] Output: Data sets associated with the incoming and outgoing lines of the power receiving unit bound to the partition identifier and linked to the corresponding incoming and outgoing lines. , .

[0185] Technical significance: The logical power supply zoning rules strictly define the zoning behavior under different station types through mathematical expressions, so that subsequent operation instructions can be generated by simply checking the incoming line status of each zone, without having to trace the power supply affiliation of each line.

[0186] The process of step S3 is as follows: Figure 4 As shown.

[0187] Further, step S4 includes the following:

[0188] Step S4: Integrated semantic tag encoding and temporal traversal:

[0189] Step Description: For each group of substations with hierarchical connections, a semantic tag is formed by combining the outgoing line information of the upper-level substation and the incoming line information of the downstream substation, for example, "A substation 10kV #1 outgoing line 911 switch - C substation 10kV #1 incoming line 912 switch". This tag simultaneously carries the following three functions:

[0190] (1) Representing the topological connection relationship between adjacent station buildings;

[0191] (2) Indicate the direction of current;

[0192] (3) The original text data directly used as instructions for nuclear phase operation and self-starting test.

[0193] Technical Problem: In existing technologies, topology relationships, current direction, and operation text are stored in fragmented fields, resulting in data redundancy and cumbersome retrieval. Technical Benefit: A single semantic tag runs through the entire process of topology determination, device aggregation, and instruction generation, enabling data reuse, simplifying data links, and improving computational efficiency.

[0194] In one embodiment of the present invention, step S4 further includes the following:

[0195] Step S4 is responsible for encoding the topology analysis results into a unified semantic tag format and arranging the processing order of the powered units according to the electrical safety timing sequence.

[0196] Input: The data set associated with the incoming and outgoing lines of the power receiving unit with the bound partition identifier output in step S3. , .

[0197] Processing steps:

[0198] Step S41: Semantic Tag Encoding: Generate integrated semantic tags using a four-segment fixed structure. Let the upstream station name be... The upstream qualifying name is The downstream station building is named The downstream incoming line name is , Where i and j are respectively and The incoming and outgoing lines are numbered logarithmically, with each corresponding to a semantic tag. The semantic tag set, Tag, is then defined as follows:

[0199] ;

[0200] Then a single semantic tag is defined as:

[0201] ;

[0202] Information carrying function I(a single semantic tag) ) is defined as:

[0203] ;

[0204] This refers to topology connection information;

[0205] This is information about the direction of the current. ;

[0206] This refers to the original text information of the operation ticket.

[0207] Ordered power receiving blocking model:

[0208] ;

[0209] u represents the complete set of power receiving units. ,

[0210] n is the total number of station buildings. , ;

[0211] Let g be a directed graph containing the set of all directed edges.

[0212] ,

[0213] side express towards powered by;

[0214] f is a status flag function, f(U)=0 indicates that station U has not completed all operations, and f(U)=1 indicates that station U has completed all operations;

[0215] y is the locking determination operator. y(U)=0 means the locking is released, allowing passage and continuing to activate the next-level station. y(U)=1 means station U is locked and the activation of the next-level station is prohibited.

[0216] Step S42: Preliminary definitions, including the following:

[0217] Definition 1: Upstream unit set. For a power receiving unit U, its upstream unit set is defined as:

[0218] ;

[0219] If U is the power supply station, then .

[0220] Definition 2: State flag set, the state flags of all powered units are:

[0221] ;

[0222] The initial state of the power supply station meets the following requirements:

[0223] ;

[0224] Definition 3: Residual unit set, the set of remaining units before the t-th iteration. initial value

[0225] Definition 4: The current batch release set, the set of stations released in the t-th round. initial value

[0226] (2) Core Formula

[0227] Formula 1: Locking Operator

[0228] ;

[0229] If the product of the status markers of the forward station is all 1, it means that all operations have been completed, then the lockout is released and passage is allowed. If any operation has not been performed, the lockout remains in place.

[0230] when Agreement .

[0231] y=0 means to release the lock, and y=1 means to keep the lock engaged.

[0232] Formula 2: Set of blocks released in the current batch

[0233] ;

[0234] The stations that are currently released from lockdown in batch t are the same stations that were released in batch t-1.

[0235] Formula 3: State Update Function

[0236] ;

[0237] All operations for the stations released in this batch have been completed. The status flag for this batch has been updated to match the previous batch, which is 1.

[0238] Formula 4: Update the residual set function:

[0239] ;

[0240] Once all operations in the current batch have been completed, all stations from the current batch will be removed from the remaining collections.

[0241] Through mathematical transformation, the core safety rule of power distribution network transmission operations—that "power can only be transmitted downstream after all upstream station operations are completed"—is converted into a built-in interlocking decision model in the algorithm. This ensures that before any receiving unit is executed, all its upstream receiving units have completed all operations and transmitted power downstream. Simultaneously, the power supply path strictly adheres to the upstream-downstream sequence to prevent commands from mistakenly crossing levels of authority.

[0242] Output: Sequence of power receiving units that have been unlocked and released. An integrated semantic tag collection.

[0243] The process of step S4 is as follows: Figure 5 As shown.

[0244] Further, step S5 includes the following:

[0245] Step S5: Multi-service security ticket generation, instruction item verification, and operation ticket output:

[0246] Step Description: Integrate the initial state confirmation, phase verification, and automatic transfer switch test instructions generated during the topology traversal process, arrange them in upstream and downstream order, and output a complete distribution network operation ticket that can be directly executed. The initial state of the energizing equipment needs to be confirmed one by one based on whether the downstream substation connected to the outgoing line requires phase verification. The topology traversal strictly follows the electrical hierarchy of "power source side → upstream substation → downstream substation," forming a fixed operation sequence. This enforces that the upstream substation must complete all phase verification and automatic transfer switch test operations before executing the process of energizing the downstream substation. After generating the instruction ticket, perform validity checks on the initial and target states within each instruction item, and continuity checks on the equipment states between items.

[0247] Technical Problem: Existing technology lacks native operational sequence constraints, making upstream testing operations prone to causing downstream automatic transfer switch malfunctions. Technical Effect: By solidifying the operational sequence through a hierarchical traversal, the risk of downstream automatic transfer switch malfunctions caused by electrical disturbances from upstream phase verification and automatic transfer switch testing is avoided at the source of the process, achieving physical and logical anti-malfunction interlocking constraints. Further protection for the correctness and security of the instruction ticket is added through the verification of the legality of the initial and target states within the equipment items and the verification of the continuity of equipment states between items.

[0248] In one embodiment of the present invention, step S5 further includes the following:

[0249] Step S5 is responsible for automatically generating complete power supply, phase verification, and standby automatic switching test operation instruction tickets based on the output of the preceding modules.

[0250] Input: Sequence of power receiving units to release the lockout Integrated semantic tags and business tags input in module one .

[0251] Processing steps:

[0252] Step S51: Initial state confirmation and electrical isolation preprocessing: Call the built-in electrical isolation operator The output of the isolation operator is determined by the following formula:

[0253] ;

[0254] For power receiving unit Business tag set ,

[0255] Where 0 represents no phase verification required, and 1 represents phase verification required (all stations equipped with automatic start-up tests need to undergo phase verification first, so it is only necessary to determine whether electrical isolation is required based on the phase verification mark).

[0256] for The station building's outbound assembly point;

[0257] for One of the lines leading out of the station building;

[0258] for The current flows to the downstream station wiring;

[0259] For the station building to which the downstream connection belongs;

[0260] If the downstream power receiving unit carries a phase-matching mark or a standby automatic transfer mark, the operator outputs a control command to set the initial state of the corresponding outgoing line of this level to hot standby, thereby constructing an electrical isolation zone and isolating the upstream test disturbance from being transmitted downstream.

[0261] Except for the outgoing line bays that require isolation, all other incoming and outgoing lines in the station building are in operation. Therefore, the formula for calculating the status of the remaining line bays is:

[0262]

[0263] but The initial equipment state formula for power supply to the station building is:

[0264] ;

[0265] Step S52: Service tag identification and instruction generation:

[0266] Instruction ticket by Initial state confirmation This is a nucleus phase operation command. It consists of instructions for preparing for automatic start-up tests. Station command sequence The generation rule is:

[0267] ;

[0268] is the power receiving unit service tag set;

[0269] , where 0 represents no need for automatic bus transfer test, and 1 represents need for automatic bus transfer test;

[0270] then the full operation order T formula is:

[0271]

[0272] u is a station; set;

[0273] wherein on-site confirmation of initial state, is the phase verification operation command chain (upper power outlet energization → secondary side phase verification notification → switch opening and closing operation → closed loop and open loop operation),

[0274] is the automatic bus transfer test operation sequence (exit charging protection → simulate main power loss → confirm correct action of automatic bus transfer → restore normal operation mode). All stations, regardless of whether phase verification and automatic bus transfer test are required, need to generate , then according to and generate corresponding phase verification and automatic bus transfer command items.

[0275] Continuous management and control of equipment status:

[0276] Core idea:

[0277] Command item template: The 10kV 901 switch of A substation changes from operation ① to hot standby ②.

[0278] Annotation: ① is the initial state of the 10kV 901 switch of A substation; ② is the target state of the 10kV 901 switch of A substation.

[0279] For a single command item, if the initial state and the target state are different, it is qualified; otherwise, it is unqualified, which serves as the single command item check.

[0280] For the command sequence of the same device in the same command sheet, starting from the first command, check the state continuity of adjacent commands pair by pair.

[0281] the target state of the first command and the initial state of the second command;

[0282] The target state of the second instruction and the initial state of the third instruction;

[0283] ...

[0284] The target state of the second-to-last instruction and the initial state of the last instruction.

[0285] In consecutive instruction entries for the same device, the target state of the previous entry and the initial state of the next entry must be consistent for the state to be considered continuous and valid; otherwise, it is invalid.

[0286] Unique thermal encoding of device status:

[0287] ;

[0288] ;

[0289] ;

[0290] ;

[0291] The entire operation ticket is designated as T, and the complete set of equipment within the ticket is designated as follows: , where n is the total number of devices.

[0292] It is equipment The i-th instruction, It is the initial state in the instruction.

[0293] This is the target state in the instruction. Therefore, the matching function for adjacent pairs is the product of the initial state one-hot encoding matrix and the transpose of the target state one-hot encoding matrix:

[0294] ;

[0295] Formula 1: Single instruction validity check function:

[0296] ;

[0297] Formula 2: Global continuity determination function for instruction tickets of the same device:

[0298] like ,

[0299] but A product of 1 indicates that adjacent instruction states on the same device are consecutive;

[0300] like ,

[0301] but A product of 0 indicates that adjacent instruction states on the same device are not consecutive.

[0302] For the same device with m instruction items in a single ticket, its state continuity function The matching function values ​​of m-1 adjacent pairs are multiplied together to determine the result.

[0303] ;

[0304] Formula 3: Global Continuity Determination Function for Unanimous Votes

[0305] Instruction Ticket Global Continuity Determination Function for:

[0306] ;

[0307] Command integration output:

[0308] All operation instructions are integrated according to the upstream priority sequence, and standardized distribution network operation tickets that can be directly executed on site are generated and output to the DMS dispatch workstation.

[0309] Output: Complete switching operation instruction ticket.

[0310] The process of step S5 is as follows: Figure 6 As shown.

[0311] Furthermore, this invention uses logical power supply partitions as logical aggregation carriers, which are different from actual topology connection information and are only used for data grouping and operation order logical judgment; the breadth-first traversal method fits the power transmission characteristics of the distribution network hierarchy, and the traversal order is completely matched with the actual electrical operation specifications on site; semantic tags are used throughout the entire process of topology judgment, equipment aggregation, and instruction generation to achieve data reuse.

[0312] The above are preferred embodiments of the present invention. Any changes made to the technical solution of the present invention that do not exceed the scope of the technical solution of the present invention shall fall within the protection scope of the present invention.
