Description

Technical Field

[0001] The present invention relates to the technical field of power grid switching operations, and in particular to a switching operation ticket generating system and method with error-proof capability. Background Art

[0002] Dispatch operation tickets are dispatch instructions drafted by dispatchers before power system operations are changed to prevent operational errors. They not only guide dispatchers in correctly communicating dispatch instructions but also, to a certain extent, ensure the safety of personnel, equipment, and the power grid.

[0003] Currently, the process for creating a ticket for a switching operation involves dispatchers determining the outage scope based on the maintenance work, verifying the equipment status with on-site personnel based on the primary equipment wiring diagram, and then defining the operation sequence. The ticket is then manually entered. After the ticket is drafted, the dispatcher verifies its accuracy and submits it to the on-duty supervisor for review. This process is cumbersome, heavily reliant on manual operation by dispatchers, and lacks a safety verification mechanism.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0023] Step 3: Use the verification and ticketing module to obtain the temporary operation ticket, and match the temporary operation ticket with all operation ticket templates in the expert knowledge base one by one. If the match is successful, output the switching operation ticket.

[0038] Example 1

[0039] Currently, the process for creating a ticket for a switching operation involves dispatchers determining the outage scope based on the maintenance work, verifying the equipment status with on-site personnel based on the primary equipment wiring diagram, and then defining the operation sequence. The ticket is then manually entered. After the ticket is drafted, the operator verifies its accuracy and submits it to the on-duty supervisor for review. This process is cumbersome, heavily reliant on manual operation by dispatchers, and lacks a safety verification mechanism.

[0040] In view of the above technical problems, this embodiment provides a Figure 1 The switching operation ticket generating system with error-proof capability shown in the figure adopts an object-oriented expression method, combining objects, expert systems, databases and graphics. After a simple menu selection, the equipment and tasks of the substation are selected. The system searches and matches the corresponding data and rules in the database and expert library, and automatically generates a standard operation ticket.

[0041] The switching operation ticket generating system includes:

[0042] Standard database, associated with the SCADA system, used to store basic information of substation equipment and all operating rules corresponding to substation equipment;

[0043] The single-line diagram generation module is associated with the standard database and is used to generate a single-line diagram based on the relationship topology of each substation equipment according to the basic information of each substation equipment;

[0044] The operation ticket entry module is associated with the single-line diagram generation module and the standard database library. It is used to index the single-line diagram, select each substation equipment that needs to be switched, and enter the basic information and corresponding operation rules of each selected substation equipment in a menu selection manner to generate a temporary operation ticket;

[0045] Expert knowledge base, used to store all operation ticket templates;

[0046] The ticket verification module is associated with the operation ticket entry module and the expert knowledge base, and is used to match the temporary operation ticket with all the operation ticket templates in the expert knowledge base one by one. If the match is successful, the switching operation ticket is output.

[0047] The simulation module, linked to the single-line diagram generation module and the verification and issuance module, simulates live logic to further verify the correctness of the switching operation ticket. Because the verification and issuance module only performs a simple comparison of temporary operation tickets, and the switching process varies with actual conditions, and the knowledge records in the expert knowledge base cannot fully cover all switching situations, the simulation module is used to demonstrate live logic, further ensuring the accuracy of the switching operation panel.

[0048] The authorization authentication module is associated with the operation ticket entry module. Before a dispatcher uses the system to generate a switching operation ticket, they must first log in to the system with their username and password to prevent other unauthorized personnel from making erroneous operations.

[0049] in,

[0050] The standard data includes: multiple device information storage tables and multiple operation rule storage tables, and one device information storage table corresponds to one operation rule storage table.

[0051] The device information storage table and the operation rule storage table include a data modification interface.

[0052] The operation ticket entry module includes: a single-line diagram index unit and an operation ticket temporary storage unit; the single-line diagram index unit is associated with the single-line diagram generation module and the operation ticket temporary storage unit, and the operation ticket temporary storage unit is associated with the verification and ticket issuance module.

[0053] The ticket verification module includes: a search unit, a matching unit and a ticket issuing unit; the search unit is associated with the operation ticket temporary storage unit and the expert knowledge base, and the search unit, the matching unit and the ticket issuing unit are associated in sequence.

[0054] During use, the dispatcher first logs into the system by entering their username and password through the graphical user interface. They then click "Generate Single Line" to send a command to the single-line diagram generation module, which instructs it to retrieve device information (such as device name and location) from the annotation database and generate the single-line diagram. The dispatcher then selects the device to be switched on the generated single-line diagram and clicks "OK" to enter the operation ticket entry interface. Within the operation ticket entry interface, the dispatcher sends a command to the operation ticket entry module by selecting from a menu, instructing it to retrieve the basic information and corresponding operation rules for the selected device from the standard database and enter them into the system. After the dispatcher confirms the entry, the system automatically generates a temporary operation ticket. The verification module then matches the temporary operation ticket against all operation ticket templates in the expert knowledge base. If a match is successful, a switching operation ticket is output. If a match fails, the dispatcher is prompted to return to the operation ticket entry module to re-enter the information. Furthermore, the dispatcher can use the simulation demonstration module to perform a graphical live logic simulation to further verify the accuracy of the switching operation ticket.

[0055] The above-mentioned switching operation ticket generating system with error-proof capability has the following advantages over the existing switching operation ticket generating technology: First, the standard database is associated with the SCADA system to realize the sharing of real-time data with the SCADA system, and the equipment information collected by the SCADA system in real time is standardized and stored; it adopts an object-oriented expression method, abstracts the substation equipment into a class, and encapsulates the basic information of the substation equipment and all the corresponding operation rules of the equipment in the class for the single-line diagram generation module and the operation ticket entry module to call, so as to realize the filling of the standardized content into the operation ticket, and at the same time, the direct call method can improve the efficiency of issuing the operation ticket. Second, the single-line diagram generation module takes each class in the standard database as a graphic element, and also adopts an object-oriented expression method, and uses the basic equipment information (name, location, etc.) contained in each graphic element to perform the relational topology of each substation equipment and automatically generate a single-line diagram. Third, an expert knowledge base was established, and the equipment in the substation was arranged and combined according to the type and quantity. The equipment information and corresponding operating rules contained in all combinations were uniformly stored in the expert knowledge base, which was used by the verification and ticket issuance module to implement anti-error verification of temporary operation tickets, thereby improving the accuracy of switching operation tickets.

[0056] Example 2

[0057] A method for generating a switching operation ticket with error prevention capability comprises the following steps:

[0058] Step 1: Use the single-line diagram generation module to retrieve the basic information of each substation equipment from the standard database, perform relationship topology on each substation equipment according to the basic information of each substation equipment, and generate a single-line diagram.

[0059] Step 2: Utilize the operation ticket entry module to filter out the devices to be operated that need to be switched from the single-line diagram, retrieve the basic information of each device to be operated and the corresponding operation rules from the standard database, and generate a temporary operation ticket.

[0060] Step 3: Use the verification and ticketing module to obtain a temporary operation ticket, compare the temporary operation ticket with all the operation ticket templates in the expert knowledge base one by one, and screen out multiple operation ticket templates that have the same substation equipment information as the temporary operation ticket.

[0061] Step 4: Match the temporary operation ticket with the multiple operation ticket templates that have been screened out one by one to determine whether there are one or more operation ticket templates that meet the matching conditions; if so, output the temporary operation ticket as the final switching operation ticket; if not, use the operation ticket entry module to re-record the operation ticket information; the matching condition is: the operation rules recorded in the operation ticket template are the same as the operation rules recorded in the temporary operation ticket.

[0062] Step 5: Use the verification and ticketing module to obtain the temporary operation ticket, and match the temporary operation ticket with all operation ticket templates in the expert knowledge base one by one. If the match is successful, output the switching operation ticket.

[0063] Step 6: Use the simulation demonstration module to perform a graphic live logic simulation demonstration based on the equipment information and operation rules recorded in the switching operation ticket.

[0064] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
