Description

Technical Field

[0001] This invention belongs to the field of power system automatic control, and relates to one-click sequential control technology for power system substations. Specifically, it relates to a method, device and system for processing sequential control operation tickets for secondary equipment in intelligent substations. Background Technology

[0002] Substation one-click sequential control provides an efficient method for switching the operating status of secondary equipment such as relay protection devices. Based on pre-defined operating logic and rules, it automatically completes a series of switch engagement / disengagement operations, ultimately changing the operating status of secondary equipment such as relay protection devices, thus achieving "one-click" sequential control execution of operation tickets and secondary safety measures tickets. The sequential control operation ticket is an operation sequence stored in the monitoring host's pre-built operation ticket library for one-click sequential control. It includes the operation object, current equipment status, target equipment status, sequential control interlock signal, operation item, pre-execution conditions, and confirmation conditions. Sequential control operation tickets can be divided into two types: operations on primary equipment such as switches and disconnectors, and operations on secondary equipment such as protection devices. The sequential control operation ticket for secondary equipment such as protection devices is a combination of remote control operations on a set of secondary equipment soft switch panels. The operation item is engaging / disengaging the soft switch panel; the pre-execution condition is checking that the soft switch panel is in the engaged / disengaged state; and the confirmation condition is checking that the soft switch panel is engaged / disengaged. Sequential control operation tickets are prepared based on the actual conditions of the substation and must be approved and tested on-site before use. Tested and accepted sequential control operation tickets are stored in a pre-fabricated operation ticket library and cannot be modified arbitrarily. When performing one-click sequential control operations on secondary equipment, an accepted sequential control operation ticket stored in the pre-fabricated operation ticket library is retrieved. After a series of strict verifications, automatic execution is only possible if all conditions are met. However, if the soft pressure plate in certain operation items is already in the target state, the pre-execution conditions are not met, causing the operation ticket to fail verification and thus preventing one-click sequential control operations. These operation items where pre-execution conditions are not met are called non-compliance items. The existence of non-compliance items renders one-click sequential control of secondary equipment such as relay protection devices impractical, reducing the automation level of automatic activation / deactivation and safety measures for secondary equipment. Summary of the Invention

[0003] To address the aforementioned issues, this invention proposes a method, device, and system for processing sequential control operation tickets for secondary equipment in intelligent substations. This overcomes the shortcomings of existing intelligent substation relay protection devices and other secondary equipment where one-click sequential control is impractical, improves the adaptability of one-click sequential control in substation operation and maintenance, significantly increases operational efficiency, reduces the risk of misoperation, and shortens manual operation time.

[0004] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0005] In a first aspect, the present invention provides a method for processing sequential control operation tickets for secondary equipment in an intelligent substation, comprising:

[0006] Create a sequential control operation ticket and save it as an unverified operation ticket;

[0007] Verify unverified operation tickets and save them as verified operation tickets;

[0008] Retrieve the verified operation ticket, identify and process any non-compliant items, and generate a temporary operation ticket;

[0009] Execute temporary operation tickets;

[0010] Archive temporary operation tickets during the execution process as archived operation tickets.

[0011] Optionally, the types of sequential control operation tickets are divided into unverified operation tickets, verified operation tickets, temporary operation tickets, and archived operation tickets.

[0012] Optionally, the sequential control operation ticket is saved to the database using the sequential control operation ticket editing tool, and the type of the saved operation ticket is an unverified operation ticket.

[0013] Optionally, the step of verifying the unverified operation ticket and saving it as a verified operation ticket specifically involves:

[0014] Verify unverified operation tickets using either a power outage verification method or a non-power outage verification method;

[0015] Once an unverified operation ticket passes verification, it is saved to the pre-made operation ticket library and its type is changed to verified operation ticket.

[0016] An unverified operation ticket remains an unverified operation ticket even after verification fails.

[0017] Optionally, the step of retrieving the verified operation ticket, identifying and processing non-compliant items, and generating a temporary operation ticket specifically involves:

[0018] Retrieve the verified operation ticket;

[0019] The verified operation ticket is parsed to obtain a list of operation items. It is determined whether the confirmation conditions for each operation item have been met. If they are met, it is marked as a non-compliant item. The operation type of this non-compliant item is automatically changed from remote operation to inspection operation. The operation content description is automatically changed to "checking that the soft pressure plate is in the exit / entry state". The pre-execution conditions are deleted.

[0020] Based on the processed list of operation items, a new sequential control operation ticket is generated, which is a temporary operation ticket and saved to the operation ticket library.

[0021] Optionally, the execution of the temporary operation ticket specifically includes:

[0022] Send a list of processed non-conformities to the operator;

[0023] Once the operator's confirmation is received, the currently executing verified operation ticket will be automatically replaced with the newly generated temporary operation ticket, and the one-click sequential control operation will continue.

[0024] During execution, the system records the user name of the temporary operation ticket, the start time, the end time, the time of each step, the operation content, any abnormal alarms, and the termination of the operation.

[0025] Optionally, archiving the temporary operation ticket of the execution process as an archived operation ticket specifically involves:

[0026] After a temporary operation ticket is executed, it is archived, its type is changed to archived operation ticket, and it is stored in the operation ticket library. Archived operation tickets cannot be deleted or modified.

[0027] Secondly, the present invention provides a processing device for sequential control operation tickets of secondary equipment in intelligent substations, comprising:

[0028] The sequential control operation ticket editing tool is used to create sequential control operation tickets and save them as unverified operation tickets;

[0029] The sequential operation ticket verification tool is used to verify unverified operation tickets and save them as verified operation tickets;

[0030] The one-click sequential control program is used to retrieve the verified operation tickets, identify non-compliant items and process them, and generate temporary operation tickets; it is also used to execute temporary operation tickets and archive the temporary operation tickets during the execution process into archived operation tickets.

[0031] Thirdly, the present invention provides a processing system for sequential control operation tickets of secondary equipment in intelligent substations, including a processor and a storage medium;

[0032] The storage medium is used to store instructions;

[0033] The processor is configured to operate according to the instructions to perform the steps of the method according to any one of the first aspects.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] This invention can automatically identify and process non-conformities in verified operation tickets, saving them as executable temporary operation tickets that conform to the actual site conditions. Without modifying the verified operation tickets, and after operator confirmation, one-click sequential control operation continues to complete the switching of the operating status of secondary equipment such as relay protection devices. After the temporary operation ticket is executed, it is archived for historical retrieval. This invention overcomes the shortcomings of existing intelligent substation relay protection device and other secondary equipment sequential control operation tickets that do not match the actual site conditions, which makes one-click sequential control impractical. It improves the adaptability of one-click sequential control in substation operation and maintenance work, can significantly improve operational efficiency, reduce the risk of misoperation, and shorten manual operation time, especially in large-scale high-voltage intelligent substations.

[0036] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings, wherein:

[0037] Figure 1 This is a flowchart illustrating a method for processing sequential control operation tickets for secondary equipment in an intelligent substation according to an embodiment of the present invention. Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the scope of protection of the invention.

[0039] The application principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] This invention provides a method for processing sequential control operation tickets for secondary equipment in intelligent substations, such as... Figure 1 As shown, the specific steps include:

[0042] Step 1: Use the sequential control operation ticket editing tool to create a sequential control operation ticket:

[0043] Sequential control operation tickets are created for secondary equipment such as relay protection devices. Multiple sequential control operation tickets can be created for one secondary equipment. Each sequential control operation ticket needs to specify its current equipment status, target equipment status, operation task name, sequential control interlocking signal and other information.

[0044] Add an operation item list to each sequential control operation ticket, set the operation object of each operation item, i.e. a certain soft pressure plate of the device; set the operation type of each operation item, i.e. remote control type, which can be putting in or taking out the soft pressure plate; set the operation content description, pre-execution conditions, confirmation conditions and other information for each operation item.

[0045] Save the sequential control operation ticket to the operation ticket database. The saved operation ticket type is unverified operation ticket.

[0046] In one specific embodiment of the present invention, in step 1, the current equipment state and target equipment state of secondary equipment such as relay protection devices can be "in operation," "out operation," or "under maintenance," etc., and each equipment state corresponds to the actual operation / deactivation state of a set of soft pressure plates of this secondary equipment. In step 1, after the sequential control operation ticket editing tool opens and modifies the verified operation ticket, the operation ticket type changes from verified to unverified.

[0047] In one specific embodiment of the present invention, in step 1, after setting the operation object and operation type of each operation item, its operation content description, execution preconditions, and confirmation conditions can be automatically generated. The automatically generated operation content description, execution preconditions, and confirmation conditions are shown in Table 1.

[0048] Table 1

[0049]

[0050] Step 2: Use the sequential operation ticket verification tool to verify the unverified operation tickets:

[0051] The sequential operation ticket verification tool can be run on the monitoring host to verify unverified operation tickets using either a power outage verification method or a non-power outage verification method.

[0052] The verification process involves checking various conditions of the sequential control operation ticket, including checking the operation conditions, verifying the current equipment status before execution, judging the sequential control interlock signal, judging the overall station accident, judging the conditions before single-step execution, verifying the built-in anti-misoperation interlock of the single-step monitoring system, verifying the anti-misoperation of the single-step intelligent anti-misoperation host, and judging the single-step confirmation conditions. After all conditions are successfully verified, the unverified operation ticket passes the verification.

[0053] After verification, the operation ticket is saved to the pre-made operation ticket library, and the type is changed to verified operation ticket.

[0054] The operation ticket remains unverified even after the verification failed.

[0055] Step 3: Activate the one-click sequential control program to identify and process any non-compliant items on the verified operation tickets, and generate a temporary operation ticket.

[0056] Run a one-click sequential control program on the monitoring host to retrieve a verified operation ticket whose current equipment status matches the actual operating status of the substation.

[0057] The one-click sequential control program parses the verified operation ticket to obtain a list of operation items and determines whether the confirmation conditions for each operation item have been met. If they are met, the item is marked as non-compliant, and the operation type of this non-compliant item is automatically changed from remote operation to check operation. The operation description is automatically changed to "checking that the soft pressure plate is in the exit / entry state," and the pre-execution conditions are deleted. If the conditions are not met, this operation item is not a non-compliant item and no action is taken.

[0058] The one-click sequential control program replaces the list of operation items in the verified operation ticket with the processed list of operation items, generates a new sequential control operation ticket, which has no non-compliance items, is a temporary operation ticket, and is saved to the operation ticket library.

[0059] In one specific embodiment of this invention, in step 3, a one-click sequential control program is run on the monitoring host. If the retrieved sequential control operation ticket is an unverified operation ticket, an error message dialog box pops up, prohibiting retrieval. Only verified operation tickets can be retrieved. Table 2 shows a comparison of the operation type, operation content description, pre-execution conditions, and confirmation conditions before and after handling non-compliant items.

[0060] Table 2

[0061]

[0062] Step 4: Execute the temporary operation ticket using the one-click sequential control program.

[0063] The one-click sequential control program pops up a dialog box, prompting the operator with a list of non-compliant items that have been automatically processed. After the operator confirms that everything is correct, a permission verification dialog box pops up. The operator enters their username and password to verify their permissions. Only after the verification is successful can the one-click sequential control operation continue.

[0064] The one-click sequential control program will automatically replace the currently executing verified operation ticket with a newly generated temporary operation ticket. The interface should show that the currently executing operation ticket has been updated to a temporary operation ticket, and the description of the non-compliant operation has changed.

[0065] The one-click sequential control program executes the newly generated temporary operation ticket. The execution process is the same as that of the verified operation ticket, including simulation and instruction execution.

[0066] During the execution of the one-click sequential control program, information such as the user name of the temporary operation ticket, start time, end time, operation time of each step, operation content, abnormal alarms, and operation termination is recorded. The above operation records are stored in the history database and cannot be deleted or modified, but can be queried, printed, and exported.

[0067] Step 5: Archive temporary operation tickets using the one-click sequential control program.

[0068] After the one-click sequential control program completes the execution of a temporary operation ticket, it archives the ticket, changing its type to archived operation ticket, and stores it in the operation ticket database. Archived operation tickets cannot be deleted or modified; they can only be queried.

[0071] The sequential control operation ticket editing tool is used to create sequential control operation tickets and save them as unverified operation tickets;

[0073] The one-click sequential control program is used to retrieve the verified operation tickets, identify non-compliant items and process them, and generate temporary operation tickets; it is also used to execute temporary operation tickets and archive the temporary operation tickets during the execution process into archived operation tickets.

[0074] The rest are the same as in Example 1.
