Description

Technical Field

[0001] This invention relates to the field of power system technology, and in particular to a logical closed-loop auditing method and system between two sets of related operation tickets. Background Technology

[0002] In substation switching operations, the two related sets of operation tickets (such as a power outage operation ticket and a power restoration operation ticket) must form a strict logical closed loop. For example, the power restoration operation should start from the equipment position after the power outage operation, and the power restoration operation must accurately restore the equipment position to the initial position before the power outage operation.

[0003] However, the logical closed-loop review between the two sets of related operation tickets mainly relies on manual review, which requires dynamic state reconstruction and reverse tracking of dozens to hundreds of operation steps. However, the above manual review mode is unreliable, with the following specific defects: (1) Low efficiency: It relies on manual comparison item by item, which is time-consuming; (2) Poor reliability: It is very easy to miss logical errors due to fatigue or tracking errors in complex operation history (such as multiple operations on a single device), which constitutes a direct risk of misoperation; (3) Low degree of automation: In order to complete the comparison, it is often necessary to print paper tickets for offline verification. This process is not only environmentally friendly, but also highlights the drawback of not being able to automatically close the logical loop online.

[0004] Therefore, there is an urgent need for a method that can replace manual labor and automatically, accurately, and efficiently review the logical loop between two sets of related operation tickets, which can solve the problems of low efficiency, poor reliability, and low degree of automation in the existing manual review methods. Summary of the Invention

[0005] The technical problem to be solved by the embodiments of the present invention is to provide a logical closed-loop audit method and system between two sets of related operation tickets, which can solve the problems of low efficiency, poor reliability and low degree of automation of the existing manual audit method.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a logical closed-loop audit method for two sets of related operation tickets, the method comprising the following steps: Obtain the two sets of operation tickets associated with the substation switching operation, including the power outage operation ticket and the power supply operation ticket; Both the power outage operation ticket and the power restoration operation ticket are analyzed to identify multiple first key devices whose positions have changed after performing operations with associated operation verbs in the same operation steps from the power outage operation ticket, and multiple second key devices whose positions have changed after performing operations with associated operation verbs in the same operation steps from the power restoration operation ticket. The first and last operation records of each first key device in the power outage operation ticket and the first and last operation records of each second key device in the power restoration operation ticket are then statistically analyzed. Each first and last operation record includes the device's identifier, its position before the operation, and its position after the operation. Based on predetermined cross-validation rules, it is verified whether the last operation record of all first key devices corresponds one-to-one with the first operation record of all second key devices, and whether the first operation record of all first key devices corresponds one-to-one with the last operation record of all second key devices. Furthermore, based on the verification results, the reasonableness of each operation step containing associated operation verbs in the power outage operation ticket and the power restoration operation ticket is reviewed.

[0007] The cross-validation rules are as follows: the identifiers of all first key devices should form a one-to-one mapping relationship with the identifiers of all second key devices and have the same number; the operation before and after the last operation record of each first key device should be the opposite of the operation before and after the first operation record of its corresponding mapped second key device; and the operation before and after the first operation record of each first key device should be the opposite of the operation before and after the last operation record of its corresponding mapped second key device.

[0008] Specifically, step S3 includes: If the verification results show that all the identifiers of the first key equipment and all the identifiers of the second key equipment form a one-to-one mapping relationship and have the same number, and the operation before and after the last operation record of each first key equipment should be opposite to the operation before and after the first operation record of its corresponding mapped second key equipment, and the operation before and after the first operation record of each first key equipment should be opposite to the operation before and after the last operation record of its corresponding mapped second key equipment, then the operation steps containing the associated operation verbs in the power outage operation ticket and the power restoration operation ticket can be reasonably approved.

[0009] Step S3 further includes: If the verification result shows that at least one first key device identifier does not form a one-to-one mapping relationship with any second key device identifier due to different numbers, and the operation before and after positions of the last operation record of all other remaining first key devices that form identifier mapping relationships are opposite to the operation before and after positions of the first operation record of their corresponding mapped second key devices, and the operation before and after positions of the first operation record of all other remaining first key devices that form identifier mapping relationships are opposite to the operation before and after positions of the last operation record of their corresponding mapped second key devices, then all operation steps in the power outage operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving first key devices that do not form identifier mapping relationships. Furthermore, all operation steps in the power supply operation ticket containing associated operation verbs involving second key devices with identifier mapping relationships can be reasonably approved.

[0010] Step S3 further includes: If the verification result shows that at least one second key device identifier does not form a one-to-one mapping relationship with any first key device identifier due to different numbers, and the operation before and after positions of the last operation record of all other remaining second key devices that form identifier mapping relationships are opposite to the operation before and after positions of the first operation record of their corresponding mapped first key device, and the operation before and after positions of the first operation record of all other remaining second key devices that form identifier mapping relationships are opposite to the operation before and after positions of the last operation record of their corresponding mapped first key device, then all operation steps in the power supply operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving second key devices that do not form identifier mapping relationships. Furthermore, all operation steps in the power outage operation ticket containing associated operation verbs involving first key devices with identifier mapping relationships can be reasonably approved.

[0011] Step S3 further includes: If the verification result shows that at least one identifier of a first key device and an equal number of identifiers of second key devices do not form a one-to-one mapping relationship due to different numbers, and the operation sequence of the last operation record of all other remaining first key devices that form an identifier mapping relationship should be opposite to the operation sequence of the first operation record of their corresponding mapped second key devices, and the operation sequence of the first operation record of all other remaining first key devices that form an identifier mapping relationship should be opposite to the operation sequence of the last operation record of their corresponding mapped second key devices, then all operation steps in the power outage operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving first key devices that do not form an identifier mapping relationship, which cannot be reasonably approved. Furthermore, all operation steps in the power supply operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving second key devices that do not form an identifier mapping relationship, which cannot be reasonably approved.

[0012] The first key equipment and the second key equipment both include a switch, a switch trolley, a switch cabinet, a grounding switch, and a knife switch; the associated operation verbs include disconnect, close, pull open, remove, switch, remotely reach, and pull to.

[0013] This invention also provides a logical closed-loop audit system between two sets of related operation tickets, including: The associated operation ticket acquisition unit is used to acquire two sets of associated operation tickets in the substation switching operation, including the power outage operation ticket and the power supply operation ticket; The key equipment and operation record analysis unit is used to analyze both the power outage operation ticket and the power restoration operation ticket to obtain multiple first key equipment with positional changes after performing operations with associated operation verbs in the same operation steps from the power outage operation ticket, and multiple second key equipment with positional changes after performing operations with associated operation verbs in the same operation steps from the power restoration operation ticket. The unit also calculates the first and last operation records for each first key equipment in the power outage operation ticket, and the first and last operation records for each second key equipment in the power restoration operation ticket. Each first and last operation record includes the equipment's identifier, its position before the operation, and its position after the operation. The logical closed-loop audit unit is used to verify, based on predetermined cross-validation rules, whether the last operation record of all first key devices corresponds one-to-one with the first operation record of all second key devices, and whether the first operation record of all first key devices corresponds one-to-one with the last operation record of all second key devices. Furthermore, based on the verification results, it audits the reasonableness of each operation step containing associated operation verbs in the power outage operation ticket and the power restoration operation ticket.

[0014] The cross-validation rules are as follows: the identifiers of all first key devices should form a one-to-one mapping relationship with the identifiers of all second key devices and have the same number; the operation before and after the last operation record of each first key device should be the opposite of the operation before and after the first operation record of its corresponding mapped second key device; and the operation before and after the first operation record of each first key device should be the opposite of the operation before and after the last operation record of its corresponding mapped second key device.

[0015] The first key equipment and the second key equipment both include a switch, a switch trolley, a switch cabinet, a grounding switch, and a knife switch; the associated operation verbs include disconnect, close, pull open, remove, switch, remotely reach, and pull to.

[0016] Implementing the embodiments of the present invention has the following beneficial effects: This invention transforms the complex mental verification that takes tens of minutes to perform manually into a two-way cross-verification that can be completed automatically by a computer in seconds. It uses closed-loop logic cross-verification to ensure the safe relay of the operation chain and the accurate return of position changes, thus forming a complete logical closed-loop verification without any omissions or blind spots. This results in an order-of-magnitude improvement in review efficiency, thereby solving the problems of low efficiency, poor reliability and low automation in existing manual review methods. Attached Figure Description

[0017] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, obtaining other drawings based on these drawings without creative effort still falls within the scope of the present invention.

[0018] Figure 1 A flowchart illustrating a logical closed-loop audit method between two sets of related operation tickets provided in this embodiment of the invention; Figure 2 is a schematic diagram of the structure of a logical closed-loop audit system between two sets of related operation tickets provided in an embodiment of the present invention. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown in the figure, this is a logical closed-loop audit method between two sets of related operation tickets proposed in an embodiment of the present invention. The method includes the following steps: Step S1: Obtain the two sets of operation tickets associated with the substation switching operation, including the power outage operation ticket and the power supply operation ticket; The specific process involves extracting two related sets of operation tickets (such as power outage operation ticket and power restoration operation ticket) during substation switching operations and conducting a logical closed-loop review.

[0021] Step S2: Analyze both the power outage operation ticket and the power restoration operation ticket to obtain multiple first key devices whose positions have changed after performing operations with associated operation verbs in the same operation steps from the power outage operation ticket, and multiple second key devices whose positions have changed after performing operations with associated operation verbs in the same operation steps from the power restoration operation ticket. Calculate the first and last operation records for each first key device in the power outage operation ticket, and the first and last operation records for each second key device in the power restoration operation ticket. Each first and last operation record includes the device's identifier, its position before the operation, and its position after the operation. The specific process is as follows: First, the power outage operation tickets (such as the first group of operation tickets) and the power restoration operation tickets (such as the second group of operation tickets) are automatically parsed to identify multiple first key devices in the power outage operation ticket whose positions change after performing operations with the associated operation verbs contained in the same operation steps, and to identify multiple second key devices in the power restoration operation ticket whose positions change after performing operations with the associated operation verbs contained in the same operation steps. Among them, the associated operation verbs include disconnect, close, pull open, remove, switch, remote, and pull to. Both the first and second key devices include switches, switch trolleys, switch cabinets, grounding switches, and disconnectors, which are operable devices.

[0022] It is understandable that the specific manifestations of the operational changes of the associated operation verbs include changes in position or state before and after the operation, such as from opening to closing, from closing to opening, from maintenance to testing, from testing to operation, from closing to opening, and from opening to closing. The specific situation can be designed according to the actual situation, and will not be elaborated here.

[0023] Secondly, for each key device in each set of operation tickets, two key operations are automatically extracted and recorded, including the first operation record and the last operation record; the first operation record and the last operation record both include the device's identification, its position before the operation, and its position after the operation.

[0024] It should be noted that if a critical device has only one operation record, the first operation record is the last operation record.

[0025] Step S3: Based on the predetermined cross-validation rules, verify whether the last operation record of all first key devices corresponds one-to-one with the first operation record of all second key devices, and verify whether the first operation record of all first key devices corresponds one-to-one with the last operation record of all second key devices. Further, based on the verification results, review the reasonableness of each operation step containing the associated operation verb in the power outage operation ticket and the power restoration operation ticket.

[0026] The specific process is as follows: First, set cross-validation rules, specifically that the identifiers of all first key devices should form a one-to-one mapping relationship with the identifiers of all second key devices and have the same number; the operation before and after the last operation record of each first key device should be the opposite of the operation before and after the first operation record of its corresponding mapped second key device; and the operation before and after the first operation record of each first key device should be the opposite of the operation before and after the last operation record of its corresponding mapped second key device.

[0027] It is understandable that cross-validation rules include mapping verification, operational consistency verification, and location recovery verification. Among them, mapping verification: the identifier of the first critical equipment in the power outage operation ticket and the identifier of the second critical equipment in the power restoration operation ticket form a one-to-one correspondence. They can be the same identifier with the same number, or they can be different identifiers but with the same number, etc.

[0028] Operational continuity verification: Verify whether the last operation record of all first critical equipment in the power outage operation ticket corresponds one-to-one with the first operation record of all second critical equipment in the power restoration operation ticket (i.e., the equipment numbers are the same, and the positions before and after the operation are interchanged, that is, "the position after the operation of one record is the same as the position before the operation of another record, and at the same time, its position before the operation is the same as the position after the operation of another record"). This verification is used to ensure that the operation of the power restoration operation ticket is a safe and continuous continuation from the position after the operation of the power outage operation ticket.

[0029] Position recovery verification: Verify whether the first operation record of all first critical equipment in the power outage operation ticket corresponds one-to-one with the last operation record of all second critical equipment in the power restoration operation ticket (i.e., the equipment number is the same, and the positions before and after the operation are interchanged, that is, "the position after the operation of one record is the same as the position before the operation of another record, and at the same time, its position before the operation is the same as the position after the operation of another record"). This is used to verify and ensure that after the power restoration operation ticket is completed, the equipment position has been accurately restored to the position before the start of the power outage operation ticket.

[0030] Secondly, the reasonableness of each operation step containing related operation verbs in the power outage operation ticket and power restoration operation ticket is as follows: (1) The mapping verification, operation continuity verification and position recovery verification are all passed: If the verification result is that the identifiers of all first key equipment and the identifiers of all second key equipment form a one-to-one mapping relationship and have the same number, the operation before and after the last operation record of each first key equipment should be opposite to the operation before and after the first operation record of its corresponding mapped second key equipment, and the operation before and after the first operation record of each first key equipment should be opposite to the operation before and after the last operation record of its corresponding mapped second key equipment, then the operation steps containing related operation verbs in the power outage operation ticket and power supply operation ticket can be reasonably passed.

[0031] (2) The mapping verification passed, and both the operation consistency verification and the position recovery verification passed: (2.1) There are redundant first key devices that are not mapped one-to-one with the identifiers of any of the second key devices. If the verification result shows that at least one of the identifiers of the first critical device does not form a one-to-one mapping relationship with the identifier of any second critical device due to different numbers, and the operation before and after positions of the last operation record of all other first critical devices that form an identifier mapping relationship should be opposite to the operation before and after positions of the first operation record of their corresponding mapped second critical device, and the operation before and after positions of the first operation record of all other first critical devices that form an identifier mapping relationship should be opposite to the operation before and after positions of the last operation record of their corresponding mapped second critical device, then all operation steps in the power outage operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving the first critical device that does not form an identifier mapping relationship. Furthermore, all operation steps in the power supply operation ticket containing associated operation verbs involving the second critical device with an identifier mapping relationship can be reasonably approved.

[0032] (2.2) There are redundant second key devices that are not mapped one-to-one with the identifiers of any of the first key devices. If the verification result shows that at least one second key device identifier does not form a one-to-one mapping relationship with any first key device identifier due to different numbers, and the operation before and after positions of the last operation record of all other remaining second key devices that form an identifier mapping relationship should be opposite to the operation before and after positions of the first operation record of their corresponding first key device, and the operation before and after positions of the first operation record of all other remaining second key devices that form an identifier mapping relationship should be opposite to the operation before and after positions of the last operation record of their corresponding first key device, then all operation steps in the power supply operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving second key devices that do not form an identifier mapping relationship. Furthermore, all operation steps in the power outage operation ticket containing associated operation verbs involving first key devices with identifier mapping relationships can be reasonably approved.

[0033] (2.3) There is an equal number of first key equipment and second key equipment identifiers that do not form a one-to-one mapping. If the verification result shows that at least one identifier of a first critical device and an equal number of identifiers of second critical devices do not form a one-to-one mapping relationship due to different numbers, and the operation positions before and after the last operation record of all other remaining first critical devices that form an identifier mapping relationship are opposite to the operation positions before and after the first operation record of their corresponding mapped second critical devices, and the operation positions before and after the first operation record of all other remaining first critical devices that form an identifier mapping relationship are opposite to the operation positions before and after the last operation record of their corresponding mapped second critical devices, then all operation steps in the power outage operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving first critical devices that do not form an identifier mapping relationship. Furthermore, all operation steps in the power supply operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving second critical devices that do not form an identifier mapping relationship.

[0034] It should be noted that this invention is not only used for the logical closed-loop verification between two sets of operation tickets related to substation switching operation management, but also for verifying the logical consistency and reversibility between a series of operation instructions issued by the dispatching authority in the safety verification of power grid dispatching instruction tickets, and for automatically verifying the logical integrity between safety measure placement tickets and safety measure removal tickets in the management of safety measures (safety measures) within the plant, preventing the omission or failure to remove or hang grounding wires, signs, etc.; and for verifying the operation tickets for the commissioning and decommissioning of relay protection devices in the commissioning and decommissioning management, ensuring that the device status is strictly restored before and after maintenance, and preventing protection maloperation or failure to operate; and for serving as a logical pre-verification module in the generation and verification of programmed operation tickets as an automated programmed operation script, ensuring that the automatically generated sequence meets the safety operation logic.

[0035] In one example, taking a power outage operation ticket and a power restoration operation ticket as examples, the application scenario of a logical closed-loop audit method between two sets of related operation tickets provided in this embodiment of the invention is further illustrated as follows: (1) The operation task of the power outage operation ticket is to change the 10kV YueTong Line F01 switch and line from the running state to the maintenance state.

[0036] At this time, the operation sequence and steps of the power outage operation ticket are shown in Table 1 below: Table 1

[0037] The task of the power supply operation ticket is to change the 10kV YueTong Line F01 switch and line from maintenance status to operation status.

[0038] At this time, the operation sequence and steps of the power supply operation ticket are shown in Table 2 below: Table 2

[0039] (2) Review process Step 1: Read the power outage operation ticket in Table 1 and the power restoration operation ticket in Table 2.

[0040] The second step involves automatically parsing the power outage operation tickets (such as the first group of operation tickets) and the power restoration operation tickets (such as the second group of operation tickets) to identify multiple key devices whose positions change after performing the operation with the associated operation verbs in the power outage operation ticket. These include the key device "YueTong Line F02 switch" with the associated operation verb "disconnect", the key device "10kV YueTong Line F01 switch cabinet" with the associated operation verbs "change handle 1QK" and "disconnect control circuit circuit circuit breaker 1MCB2", the key device "YueTong Line F01 switch trolley" with the associated operation verbs "remotely", "suspend" and "pull", and the key device "YueTong Line F01 line side grounding switch" with the associated operation verb "close".

[0041] Meanwhile, it was found that the first critical equipment "Yuetong Line F02 Switch" in the power outage operation ticket had only one operation record, in operation step 4, the position before operation was closed and the position after operation was open; the first critical equipment "10kV Yuetong Line F01 Switchgear" had an initial operation record in operation step 6.1, the position before operation was remote and the position after operation was local, and the last operation record was in operation step 21.1, the position before operation was closed and the position after operation was open; the first critical equipment "Yuetong Line F01 Switch Trolley" had three operation records, in which the initial operation record was in operation step 7, the position before operation was working and the position after operation was test, and the last operation record was in operation step 19, the position before operation was test and the position after operation was maintenance; the first critical equipment "Yuetong Line F01 Line Side Grounding Switch" had only one operation record, in operation step 12, the position before operation was opened and the position after operation was closed.

[0042] Table 3 below shows the operation record table for the power outage operation ticket: Table 3

[0043] In addition, identify multiple second key devices whose positions change after performing operations with the associated operation verbs contained in the power supply operation ticket, including the second key device "YueTong Line F01 switch trolley" with associated operation verbs "push to", "remove" and "remotely move", the second key device "10kV YueTong Line F01 switch cabinet" with associated operation verbs "change handle 1QK" and "close control circuit circuit circuit breaker 1MCB2", the second key device "YueTong Line F01 line side grounding switch" with associated operation verb "pull open", and the second key device "YueTong Line F01 switch" with associated operation verb "close".

[0044] Meanwhile, it was found that the second critical equipment "10kV YueTong Line F01 Switchgear" in the power supply operation ticket had the following operation records: the first operation record was in operation step 5.1, where the position before operation was open and the position after operation was closed; the last operation record was in operation step 18.1, where the position before operation was local and the position after operation was remote. The second critical equipment "YueTong Line F01 Switch Trolley" had three operation records: the first operation record was in operation step 3, where the position before operation was maintenance and the position after operation was test; the last operation record was in operation step 16, where the position before operation was test and the position after operation was working. The second critical equipment "YueTong Line F01 Line Side Grounding Switch" had only one operation record: the position before operation was closed and the position after operation was opened in operation step 11. The second critical equipment "YueTong Line F01 Switch" had only one operation record: the position before operation was open and the position after operation was closed in operation step 11.

[0045] Table 4 below shows the operation record sheet for the power outage operation ticket: Table 4

[0046] Step 3, Cross-validation: First, the first critical equipment in the power outage operation ticket, "YueTong Line F02 switch," has no corresponding identifier in the power restoration operation ticket, indicating an irrelevant operation or an incorrect equipment object. Simultaneously, the second critical equipment in the power restoration operation ticket, "YueTong Line F01 switch," also has no corresponding identifier in the power outage operation ticket, indicating an irrelevant operation or an incorrect equipment object. Therefore, step 4 in the power outage operation ticket in Table 1 involving "YueTong Line F02 switch" fails the review, and step 19 in the power restoration operation ticket in Table 2 involving "YueTong Line F01 switch" also fails the review.

[0047] Secondly, the first critical equipment in the power outage operation ticket, "10kV YueTong Line F01 switchgear," is mapped to the second critical equipment in the power restoration operation ticket, "10kV YueTong Line F01 switchgear." Furthermore, the first operation record of the first critical equipment, "10kV YueTong Line F01 switchgear," in the power outage operation ticket is that the pre-operation location is remote, and the post-operation location is local. This corresponds to the last operation record of the second critical equipment, "10kV YueTong Line F01 switchgear," in the power restoration operation ticket, which is operation step 18. In step 1, the position before the operation is local, and the position after the operation is remote, forming an opposite relationship between the positions before and after the operation. In the power outage operation ticket, the last operation record of the first key equipment "10kV YueTong Line F01 switchgear" is operation step 21.1, where the position before the operation is closed and the position after the operation is open. This is the same as the first operation record of the second key equipment "10kV YueTong Line F01 switchgear" in the power supply operation ticket, where the position before the operation is open and the position after the operation is closed, forming an opposite relationship between the positions before and after the operation.

[0048] Similarly, comparing the first critical equipment "YueTong Line F01 Switch Trolley" in the power outage operation ticket with the second critical equipment "YueTong Line F01 Switch Trolley" in the power restoration operation ticket, and comparing the first critical equipment "YueTong Line F01 Line Side Grounding Switch" in the power outage operation ticket with the second critical equipment "YueTong Line F01 Line Side Grounding Switch" in the power restoration operation ticket, will not be elaborated further here.

[0049] Finally, step 4 of the power outage operation ticket in Table 1 involving "YueTong Line F02 switch" failed the review, and step 19 of the power restoration operation ticket in Table 2 involving "YueTong Line F01 switch" failed the review. However, the operation steps involving "10kV YueTong Line F01 switchgear", "10kV YueTong Line F01 switchgear" and "YueTong Line F01 line side grounding switch" in the power outage operation ticket and power restoration operation ticket all passed the review.

[0050] At this time, the power outage operation ticket review results are shown in Table 5 below: Table 5

[0051] At this point, the specific results of the power supply operation ticket review are shown in Table 6 below: Table 6

[0052] As shown in Figure 2, this embodiment of the invention provides a logical closed-loop audit system between two sets of related operation tickets, comprising: The associated operation ticket acquisition unit 110 is used to acquire two sets of associated operation tickets in the substation switching operation, including the power outage operation ticket and the power supply operation ticket; The key equipment and operation record analysis unit 120 is used to analyze both the power outage operation ticket and the power restoration operation ticket to obtain multiple first key equipment with positional changes after performing operations with associated operation verbs in the same operation steps from the power outage operation ticket, and multiple second key equipment with positional changes after performing operations with associated operation verbs in the same operation steps from the power restoration operation ticket. It also calculates the first and last operation records for each first key equipment in the power outage operation ticket, and the first and last operation records for each second key equipment in the power restoration operation ticket. The first and last operation records each include the equipment's identifier, its position before the operation, and its position after the operation. The logical closed-loop audit unit 130 is used to verify, based on predetermined cross-validation rules, whether the last operation record of all first key devices corresponds one-to-one with the first operation record of all second key devices, and whether the first operation record of all first key devices corresponds one-to-one with the last operation record of all second key devices, and further, based on the verification results, to audit the reasonableness of each operation step containing associated operation verbs in the power outage operation ticket and the power restoration operation ticket.

[0053] The cross-validation rules are as follows: the identifiers of all first key devices should form a one-to-one mapping relationship with the identifiers of all second key devices and have the same number; the operation before and after the last operation record of each first key device should be the opposite of the operation before and after the first operation record of its corresponding mapped second key device; and the operation before and after the first operation record of each first key device should be the opposite of the operation before and after the last operation record of its corresponding mapped second key device.

[0054] The first key equipment and the second key equipment both include a switch, a switch trolley, a switch cabinet, a grounding switch, and a knife switch; the associated operation verbs include disconnect, close, pull open, remove, switch, remotely reach, and pull to.

[0055] Implementing the embodiments of the present invention has the following beneficial effects: This invention transforms the complex mental verification that takes tens of minutes to perform manually into a two-way cross-verification that can be completed automatically by a computer in seconds. It uses closed-loop logic cross-verification to ensure the safe relay of the operation chain and the accurate return of position changes, thus forming a complete logical closed-loop verification without any omissions or blind spots. This results in an order-of-magnitude improvement in review efficiency, thereby solving the problems of low efficiency, poor reliability and low automation in existing manual review methods.

[0056] It is worth noting that the various system modules included in the above system embodiments are only divided according to functional logic, but are not limited to the above division, as long as the corresponding functions can be achieved; in addition, the specific names of each functional module are only for easy differentiation and are not used to limit the scope of protection of the present invention.

[0057] Those skilled in the art will understand that all or part of the steps in the methods of the above embodiments can be implemented by a program instructing related hardware. The program can be stored in a computer-readable storage medium, such as ROM / RAM, disk, optical disk, etc.

[0058] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.

Analyze both the power outage operation ticket and the power restoration operation ticket to obtain multiple first key devices whose positions have changed after performing operations with associated operation verbs in the same operation steps from the power outage operation ticket, and multiple second key devices whose positions have changed after performing operations with associated operation verbs in the same operation steps from the power restoration operation ticket. Calculate the first and last operation records for each first key device in the power outage operation ticket, and calculate the first and last operation records for each second key device in the power restoration operation ticket. Each first and last operation record includes the device's identifier, its position before the operation, and its position after the operation. S3. Based on the predetermined cross-validation rules, verify whether the last operation record of all first key devices corresponds one-to-one with the first operation record of all second key devices, and verify whether the first operation record of all first key devices corresponds one-to-one with the last operation record of all second key devices. Furthermore, based on the verification results, review the reasonableness of each operation step containing the associated operation verb in the power outage operation ticket and the power restoration operation ticket.

2. The logical closed-loop audit method between two sets of related operation tickets as described in claim 1, characterized in that, The cross-validation rule is that the identifiers of all first key devices should form a one-to-one mapping relationship with the identifiers of all second key devices and have the same number. The operation before and after the last operation record of each first key device should be the opposite of the operation before and after the first operation record of its corresponding mapped second key device, and the operation before and after the first operation record of each first key device should be the opposite of the operation before and after the last operation record of its corresponding mapped second key device.

3. The logical closed-loop audit method between two sets of related operation tickets as described in claim 2, characterized in that, Step S3 specifically includes: If the verification results show that all the identifiers of the first key equipment and all the identifiers of the second key equipment form a one-to-one mapping relationship and have the same number, and the operation before and after the last operation record of each first key equipment should be opposite to the operation before and after the first operation record of its corresponding mapped second key equipment, and the operation before and after the first operation record of each first key equipment should be opposite to the operation before and after the last operation record of its corresponding mapped second key equipment, then the operation steps containing the associated operation verbs in the power outage operation ticket and the power restoration operation ticket can be reasonably approved.

4. The logical closed-loop audit method between two sets of related operation tickets as described in claim 2, characterized in that, Step S3 further includes: If the verification result shows that at least one first key device identifier does not form a one-to-one mapping relationship with any second key device identifier due to different numbers, and the operation before and after positions of the last operation record of all other remaining first key devices that form identifier mapping relationships are opposite to the operation before and after positions of the first operation record of their corresponding mapped second key devices, and the operation before and after positions of the first operation record of all other remaining first key devices that form identifier mapping relationships are opposite to the operation before and after positions of the last operation record of their corresponding mapped second key devices, then all operation steps in the power outage operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving first key devices that do not form identifier mapping relationships. Furthermore, all operation steps in the power supply operation ticket containing associated operation verbs involving second key devices with identifier mapping relationships can be reasonably approved.

5. The logical closed-loop audit method between two sets of related operation tickets as described in claim 2, characterized in that, Step S3 further includes: If the verification result shows that at least one second key device identifier does not form a one-to-one mapping relationship with any first key device identifier due to different numbers, and the operation before and after positions of the last operation record of all other remaining second key devices that form identifier mapping relationships are opposite to the operation before and after positions of the first operation record of their corresponding mapped first key device, and the operation before and after positions of the first operation record of all other remaining second key devices that form identifier mapping relationships are opposite to the operation before and after positions of the last operation record of their corresponding mapped first key device, then all operation steps in the power supply operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving second key devices that do not form identifier mapping relationships. Furthermore, all operation steps in the power outage operation ticket containing associated operation verbs involving first key devices with identifier mapping relationships can be reasonably approved.

6. The logical closed-loop audit method between two sets of related operation tickets as described in claim 2, characterized in that, Step S3 further includes: If the verification result shows that at least one identifier of a first key device and an equal number of identifiers of second key devices do not form a one-to-one mapping relationship due to different numbers, and the operation sequence of the last operation record of all other remaining first key devices that form an identifier mapping relationship should be opposite to the operation sequence of the first operation record of their corresponding mapped second key devices, and the operation sequence of the first operation record of all other remaining first key devices that form an identifier mapping relationship should be opposite to the operation sequence of the last operation record of their corresponding mapped second key devices, then all operation steps in the power outage operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving first key devices that do not form an identifier mapping relationship, which cannot be reasonably approved. Furthermore, all operation steps in the power supply operation ticket containing associated operation verbs can be reasonably approved except for operation steps involving second key devices that do not form an identifier mapping relationship, which cannot be reasonably approved.

The logical closed-loop audit method between two sets of related operation tickets as described in claim 1, characterized in that, Both the first key device and the second key device include a switch, a switch trolley, a switch cabinet, a grounding switch, and a knife switch; the associated operation verbs include disconnect, close, pull open, remove, switch, remotely reach, and pull to.

8. A logical closed-loop auditing system for two sets of related operation tickets, characterized in that, include: The associated operation ticket acquisition unit is used to acquire two sets of associated operation tickets in the substation switching operation, including the power outage operation ticket and the power supply operation ticket; The key equipment and operation record analysis unit is used to analyze both the power outage operation ticket and the power restoration operation ticket to obtain multiple first key equipment with positional changes after performing operations with associated operation verbs in the same operation steps from the power outage operation ticket, and multiple second key equipment with positional changes after performing operations with associated operation verbs in the same operation steps from the power restoration operation ticket. The unit also calculates the first and last operation records for each first key equipment in the power outage operation ticket, and the first and last operation records for each second key equipment in the power restoration operation ticket. Each first and last operation record includes the equipment's identifier, its position before the operation, and its position after the operation. The logical closed-loop audit unit is used to verify, based on predetermined cross-validation rules, whether the last operation record of all first key devices corresponds one-to-one with the first operation record of all second key devices, and whether the first operation record of all first key devices corresponds one-to-one with the last operation record of all second key devices.
