Description

Technical Field

[0001] This invention relates to the field of power system operation ticket technology, and in particular to a modular processing method and equipment for intelligent generation of substation operation tickets. Background Technology

[0002] With the increasing automation level of substations, the number of primary equipment has multiplied, leading to slow and inefficient judgment processes and a significant increase in the workload of maintenance personnel. Furthermore, the different operating modes of equipment within the substation and the operating modes of the surrounding power grid make it difficult or impossible to express the logical expressions for the corresponding equipment, easily resulting in operational errors. Moreover, the method used in operation tickets to handle the main wiring configuration of substations primarily involves adding attribute columns to network elements, with the wiring configuration then manually entered and saved. Consequently, when the main electrical wiring changes, the system cannot automatically update the information reflecting the wiring configuration stored in the database, causing errors in the operation ticket generation system.

[0003] Patent No. CN201410541396 describes an automatic generation method for sequential control operation tickets based on topology. The method generates a system model based on the substation wiring topology, and then generates sequential control operation tickets using the bay ID and bay description fields. However, it does not mention the specific composition of the bays or the specific steps and methods for dividing them. Summary of the Invention

[0004] To address the problem that existing technologies cannot automatically modify the wiring information stored in the database, the primary objective of this invention is to provide a modular processing method for intelligently generating substation operation tickets that effectively improves the reliability of substation switching operations, significantly enhances the level of error prevention and control, and adapts to the new power grid production management model under the new power system environment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular processing method for intelligent generation of substation operation tickets, the method comprising the following sequential steps:

[0006] (1) Obtain substation operation ticket data and divide the operation ticket data into five elements: operation object, operation task, initial state, operation rules and target state;

[0007] (2) Modularize the operation objects to generate a typical operation task library;

[0008] (3) Decompose the workflow of the operation task to be generated into modules in sequence;

[0009] (4) Input the operation task and operation object to be generated into the typical operation task library for retrieval. If the same operation task and operation object are found, verify the initial state, operation rules and target state of the operation ticket to be generated. If the initial state, operation rules and target state are the same, it means that the verification is consistent. Then the operation ticket is generated by calling the operation ticket data with the same 5 elements in the typical operation task library and issuing the ticket directly. Otherwise, if the initial state, operation rules and target state are inconsistent, the sequential decomposition module is revised and the process is returned to step (3).

[0010] Step (2) specifically includes the following steps in sequence:

[0011] (2a) Retrieve substation data and, based on the static data of the main electrical wiring configuration, divide the operation objects into all primary and secondary equipment under the jurisdiction of the dispatching authority;

[0012] (2b) Divide all primary and secondary equipment in the substation into transformer modules, busbar modules, line modules and switch modules, and the remaining undivided primary and secondary equipment exist independently as a single operation object;

[0013] The transformer module includes high-voltage side bays, medium-voltage side bays, and low-voltage side bays. Each bay includes switches, circuit breakers, grounding switches, and surge arresters for each circuit on the high, medium, and low voltage sides of the transformer. The busbar module includes bus tie switches, circuit breakers, grounding switches, and surge arresters for each busbar circuit. The line module includes feeder switches, circuit breakers, grounding switches, and surge arresters for feeder outgoing lines. The switch module includes circuit breakers, disconnect switches, grounding switches, and surge arresters for grounding transformers, reactors, capacitors, and PT cabinets within the station.

[0014] (2c) Each module is further decomposed into a single operation object, and a typical operation task library is formed according to the initial state, operation rules and target state.

[0015] Step (3) specifically includes the following steps in sequence:

[0016] (3a) Extract the primary and secondary devices included in the operation task, and determine the module to which the primary and secondary devices belong:

[0017] If it belongs to only a single module, proceed to step (3b);

[0018] If it belongs to multiple modules, proceed to step (3c);

[0019] If it does not belong to any module, proceed to step (3d);

[0020] (3b) If it is determined to be a single module, the operation task is executed in the order of the operation task and verified according to the operation rules; if the operation task order conforms to the operation rules, the operation ticket is executed in the order; if the operation task order does not conform to the operation rules, the operation order is adjusted until it conforms to the operation rules and the operation ticket is executed in the order.

[0021] (3c) If it is determined that it belongs to multiple modules, the modules are executed in sequence and the operation rules are verified. If the flow order of the operation task conforms to the operation rules, it is decomposed into a single module and returned to step (3b). If the flow order of the operation task does not conform to the operation rules, the operation order is adjusted until it conforms to the operation rules and it is decomposed into a single module and returned to step (3b).

[0022] (3d) If it is determined that it does not belong to any module, it will be executed in the order of operation tasks and verified according to the operation rules. If the process order of the operation tasks conforms to the operation rules, the process operation of the operation ticket will be executed in sequence. If the process order of the operation tasks does not conform to the operation rules, the operation order will be adjusted until it conforms to the operation rules, and the process operation of the operation ticket will be executed in sequence.

[0023] In step (4), the step of revising the sequentially decomposed modules if the initial state, operating rules, and target state do not match specifically refers to:

[0024] If the previous and next modules of a mismatched module in the operation object both match, then the mismatched module in this operation object is decomposed into a single operation object.

[0025] If the previous module verification of the incompatible modules in the operation object is also incompatible, the incompatible modules will be merged according to the merging rules; if the next module verification of the incompatible modules in the operation object is also incompatible, the incompatible modules will be merged according to the merging rules; after the modules are merged, when the operation task is decomposed sequentially by module, the merged modules will be treated as independent modules.

[0026] The merging rules are as follows:

[0027] If the incompatible modules are transformer modules and busbar modules, then merge the transformer modules into the busbar modules;

[0028] If the incompatible modules are the bus module and the line module, then the line module will be merged into the bus module;

[0029] If the incompatible modules are the bus module and the switch module, then the switch module will be merged into the bus module.

[0030] Another object of the present invention is to provide an electronic device comprising:

[0031] Processor; and

[0032] The memory stores computer program instructions that, when executed by the processor, cause the processor to perform the modular processing method for intelligent generation of substation operation tickets as described above.

[0033] The present invention also provides a computer-readable storage medium storing computer program instructions thereon, which, when executed by a processor, cause the processor to perform the modular processing method for intelligent generation of substation operation tickets as described above.

[0034] As can be seen from the above technical solution, the beneficial effects of the present invention are as follows: First, the present invention decomposes and encapsulates the operation objects of the operation ticket into various independent modules, which can perform sequential error prevention verification on a module-by-module basis when the operation ticket is generated, and can easily adjust any non-compliant items, greatly improving the efficiency of operation ticket issuance; Second, the modular intelligent generation of operation tickets can provide ticket issuers with intelligent and systematic operation ticket safety verification and operation error prevention guidance, effectively improving the reliability of substation switching operations, fully enhancing the level of error prevention and control, and adapting to the new power grid production management model under the new power system environment; Third, the modularization of operation tickets enables more accurate operation ticket generation and monitoring, especially when equipment status changes frequently, greatly reducing the risk of misoperation caused by operating condition lag, thereby improving operational safety and stability, reducing the occurrence of human error, and further ensuring the stable operation of substation equipment.

[0036] Figure 2 This is a flowchart showing the breakdown of the operation tasks in this invention in module order. Detailed Implementation

[0037] A modular processing method for intelligent generation of substation operation tickets, comprising the following sequential steps:

[0038] (1) Obtain substation operation ticket data and divide the operation ticket data into five elements: operation object, operation task, initial state, operation rules and target state;

[0039] (2) Modularize the operation objects to generate a typical operation task library;

[0040] (3) Decompose the workflow of the operation task to be generated into modules in sequence;

[0041] (4) Input the operation task and operation object to be generated into the typical operation task library for retrieval. If the same operation task and operation object are found, verify the initial state, operation rules and target state of the operation ticket to be generated. If the initial state, operation rules and target state are the same, it means that the verification is consistent. Then the operation ticket is generated by calling the operation ticket data with the same 5 elements in the typical operation task library and issuing the ticket directly. Otherwise, if the initial state, operation rules and target state are inconsistent, the sequential decomposition module is revised and the process is returned to step (3).

[0042] like Figure 1 As shown, step (2) specifically includes the following steps in sequence:

[0043] (2a) Retrieve substation data and, based on the static data of the main electrical wiring configuration, divide the operation objects into all primary and secondary equipment under the jurisdiction of the dispatching authority;

[0044] (2b) Divide all primary and secondary equipment in the substation into transformer modules, busbar modules, line modules and switch modules, and the remaining undivided primary and secondary equipment exist independently as a single operation object;

[0045] The transformer module includes high-voltage side bays, medium-voltage side bays, and low-voltage side bays. Each bay includes switches, circuit breakers, grounding switches, and surge arresters for each circuit on the high, medium, and low voltage sides of the transformer. The busbar module includes bus tie switches, circuit breakers, grounding switches, and surge arresters for each busbar circuit. The line module includes feeder switches, circuit breakers, grounding switches, and surge arresters for feeder outgoing lines. The switch module includes circuit breakers, disconnect switches, grounding switches, and surge arresters for grounding transformers, reactors, capacitors, and PT cabinets within the station.

[0046] (2c) Each module is further decomposed into a single operation object, and a typical operation task library is formed according to the initial state, operation rules and target state.

[0047] like Figure 2 As shown, step (3) specifically includes the following steps in sequence:

[0048] (3a) Extract the primary and secondary devices included in the operation task, and determine the module to which the primary and secondary devices belong:

[0049] If it belongs to only a single module, proceed to step (3b);

[0050] If it belongs to multiple modules, proceed to step (3c);

[0051] If it does not belong to any module, proceed to step (3d);

[0052] (3b) If it is determined to be a single module, the operation task is executed in the order of the operation task and verified according to the operation rules; if the operation task order conforms to the operation rules, the operation ticket is executed in the order; if the operation task order does not conform to the operation rules, the operation order is adjusted until it conforms to the operation rules and the operation ticket is executed in the order.

[0053] (3c) If it is determined that it belongs to multiple modules, the modules are executed in sequence and the operation rules are verified. If the flow order of the operation task conforms to the operation rules, it is decomposed into a single module and returned to step (3b). If the flow order of the operation task does not conform to the operation rules, the operation order is adjusted until it conforms to the operation rules and it is decomposed into a single module and returned to step (3b).

[0054] (3d) If it is determined that it does not belong to any module, it will be executed in the order of operation tasks and verified according to the operation rules. If the process order of the operation tasks conforms to the operation rules, the process operation of the operation ticket will be executed in sequence. If the process order of the operation tasks does not conform to the operation rules, the operation order will be adjusted until it conforms to the operation rules, and the process operation of the operation ticket will be executed in sequence.

[0055] In step (4), the step of revising the sequentially decomposed modules if the initial state, operating rules, and target state do not match specifically refers to:

[0056] If the previous and next modules of a mismatched module in the operation object both match, then the mismatched module in this operation object is decomposed into a single operation object.

[0057] If the previous module verification of the incompatible modules in the operation object is also incompatible, the incompatible modules will be merged according to the merging rules; if the next module verification of the incompatible modules in the operation object is also incompatible, the incompatible modules will be merged according to the merging rules; after the modules are merged, when the operation task is decomposed sequentially by module, the merged modules will be treated as independent modules.

[0058] The merging rules are as follows:

[0059] If the incompatible modules are transformer modules and busbar modules, then merge the transformer modules into the busbar modules;

[0060] If the incompatible modules are the bus module and the line module, then the line module will be merged into the bus module;

[0061] If the incompatible modules are the bus module and the switch module, then the switch module will be merged into the bus module.

[0062] In summary, this invention decomposes and encapsulates the operational objects of the operation ticket into independent modules. This allows for sequential error prevention verification on a module-by-module basis during operation ticket generation, and convenient adjustments can be made to any non-compliant items, significantly improving operation ticket issuance efficiency. The modular intelligent generation of operation tickets provides ticket issuers with intelligent and systematic operation ticket safety verification and error prevention guidance, effectively improving the reliability of substation switching operations, significantly enhancing error prevention and control levels, and adapting to the new power grid production management model under the new power system environment. The modularization of operation tickets enables more precise operation ticket generation and monitoring, especially when equipment status changes frequently, greatly reducing the risk of misoperation due to lagging operating conditions, thereby improving operational safety and stability, reducing human error, and further ensuring the stable operation of substation equipment.
