Description

Technical Field

[0001] The invention belongs to the field of electric power technology, and in particular relates to a nuclear power operation procedure digital system and a control method thereof. Background Art

[0002] Nuclear power is a safe, economical, efficient and clean energy, and is an important energy option for mankind to cope with climate change. The process of nuclear power units is particularly complex, with one unit having up to 100,000 pieces of equipment, involving nearly 300 systems (such as: turbine lubrication treatment system, chilled water system, steam generator sewage system), more than 1,000 rooms, and more than 3,000 operating procedures. Operating procedures are a set of specifications, standards and procedures formulated in the power system to ensure the safe, stable and effective operation of power equipment. It includes aspects such as power system operation management, equipment operation, accident handling, and safety precautions. Operating procedures are an important reference for operating personnel to carry out a series of operations such as regular testing, overhaul operations, and operation operations to operate on-site equipment to perform power system operations. They are important guiding documents to ensure the stable operation of nuclear power units and prevent and avoid various safety issues.

[0003] At present, most nuclear power plants have operators print office electronic procedures, operate on-site equipment according to the procedures, record equipment readings on paper procedures, manually calculate according to formulas and record formula results, compare equipment threshold requirements in the procedures to identify whether equipment operation or operation is normal, or consult historical data to analyze equipment operation trends. In addition, some nuclear power plants convert office electronic procedures into PDF files, and use PDF as the bottom layer on the mobile terminal, with a transparent mask layer on top to implement mobile terminal execution of operating procedures. The current execution method of paper operating procedures or PDF electronic operating procedures cannot meet the requirements of enterprise digital transformation and development, and cannot adapt to the development trend of Digital China. The following problems exist:

[0004] 1. All operating procedures and processes rely on offline processes

[0005] From the generation of operating procedure plans, preparation of procedure work packages (such as drawing search and delineation), plan approval and issuance, supervision during execution, handover during execution, temporary modifications during execution, monitoring during execution, completion approval after execution, and archiving after execution, all processes rely on face-to-face or telephone communication between employees, and the work effect is very poor.

[0006] 2. Lack of technical means to prevent human errors

[0007] The lack of technical means makes it impossible to quickly check the validity of the version of the regulations; it is impossible to effectively remind the wrong interval when executing the regulations; it is impossible to remind the equipment that does not belong to the unit to which the regulations belong; it is impossible to control the execution of skipped steps; there is no technical means to check the validity of the operation record value; it is impossible to discover the equipment operation trend based on the equipment history record value;

[0008] 3. Insufficient real-time monitoring means

[0009] During the on-site implementation of the procedures, apart from on-site monitoring by the operation supervisor and on-site operators reporting the on-site implementation status to the main control face-to-face or by telephone, there are no other effective technical means to monitor the progress of on-site work in real time, which is not conducive to timely response and intervention in abnormal situations on site.

[0010] 4. Historical data cannot be effectively used

[0011] Since operating procedures are still archived in paper and electronic scans, querying historical equipment operations is a time-consuming task, and there is no way to effectively analyze historical data or further utilize historical data.

[0012] 5. Unable to adapt to the development trend of digital nuclear power

[0013] In December 2022, the National Energy Administration clearly required in the "Guiding Opinions on Promoting the Digital Transformation and Development of Nuclear Power" to "promote digital production management. Build a digital production process system for nuclear power plants, explore the relationship between production management systems, operation isolation systems, digital operating procedures, and digital technical specifications, and develop mobile application APPs."

[0014] Article 37 of the Archives Law, which came into effect in 2021, clearly states that “electronic archives have the same validity as traditional carrier archives and can be used as evidence in electronic form.

[0015] Therefore, nuclear power generation companies are in urgent need of an operating procedure system and method that can break away from traditional paper operating procedures, meet the needs of mobile terminal execution, and truly realize the digitization of procedures in order to solve the above problems. Summary of the invention

[0016] The purpose of the present invention is to provide a nuclear power operation procedure digitization system and a control method thereof, so as to realize the conversion of operation specification documents in Word electronic format into digital documents, realize the transformation of operation procedures from paper execution to mobile terminal digital execution on the basis of digital documents, realize the automated management of operation plans, realize the transformation of face-to-face work handover of personnel to remote handover to improve work efficiency, realize automatic inspection and ensure the feasibility and safety of equipment operation according to the content and step requirements of digital procedure documents, realize the visualization of the on-site execution process of procedures, realize the structuring and reuse of procedure execution results, and realize the direct electronic archiving of procedure work packages.

[0059] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0060] like Figure 1 As shown, the present invention provides a nuclear power operation procedure digital system, comprising:

[0061] The original electronic operating procedure file storage system includes the ECM system for storing controlled documents and records / archives, and the public hard disk for storing uncontrolled documents.

Tasks involve approval of planned issuance of operating procedures, approval of planned termination of operating procedures, approval of temporary modification during the execution of operating procedures, and approval of completion after the completion of operating procedures.

[0064] In completed tasks, you can view task details, status tracking and flow charts.

[0065] The procedure document digitization module, the core module of this system, is used to automatically digitize Word electronic procedures and provide users with verification, online editing and confirmation functions of digital operation procedures.

[0066] The digitization module of the specification document reads the Word electronic file paragraph by paragraph through the POI component to obtain the content and style of the paragraph. The content includes: characters, paragraphs, tables, embedded objects, and pages. The style of characters includes font, size, and color; the style of paragraphs includes: indentation, space, item number, alignment, title, and numbered list; the style of tables includes: cell font and color, background color, alignment, border, column width, and row height; the style of embedded objects (such as pictures and VISIO) includes: alignment and rotation; the style of pages includes: page breaks, borders, boundaries, page size, and direction.

[0067] The read Word electronic file is saved in a structured database.

[0068] The procedure plan extraction module is used to analyze the business semantics of each paragraph according to preset rules and the location and content of the paragraph, extract the procedure plan draft from the work order management system, extract the procedure plan draft from the equipment isolation system, and automatically generate an operation procedure plan sheet.

[0069] Business semantics include: file title, version, edition, editor and reviewer, quality level, risk level, distribution, procedure execution level, etc. on the file cover page; upgrade time, upgrade reason, upgrader, etc. on the file upgrade page; description of the file body page (reference document, purpose, authorization, test cycle, estimated time, unit status, test conditions, cooperating department, risk analysis, experience feedback), test operation sheet, appendix, acceptance criteria, test evaluation and other information.

[0070] For the operating steps in the test operation sheet (table) in the procedure document, identify the contents of the operation content column, operation equipment / location column, and remarks column.

[0071] The feature extraction method is used to identify the six-tuple information of equipment operation in the procedure operation steps: equipment, equipment operation action, physical quantity, physical quantity value, physical quantity unit, and threshold range.

[0072] The procedure plan execution module is used by users to write and adjust the procedure execution plan, and complete the confirmation and issuance of the procedure execution plan.

[0073] The mobile terminal module is the core module of this system. The mobile terminal module is deployed on the mobile terminal. The mobile terminal and the server terminal communicate through the company's 5G proprietary network to realize remote interaction between the mobile terminal and the PC terminal.

[0074] The mobile terminal module includes a procedure operation check-in submodule, which is used to download the contents of the procedure operation package when online so that it can continue to be executed on the mobile terminal when there is no network; the details of the procedure operation package can be viewed on the mobile terminal, including the operation package form, digital operation procedures, related PDF, Word, pictures and other attachments; the functions of executing the procedure operation package include various operations such as pause, restart, handover, temporary modification, and termination of the operation package. When executing the procedure operation package, each mobile terminal communicates with the server in real time, and the server communicates with the PC and large-screen terminals in real time to ensure that personnel in various positions and roles can view the same operation package content in real time on different terminals. After the procedure operation package is completed, the operation operator submits it to the main control operator and the shift supervisor for review. The reviewer can modify the content of the operation package and approve the completion application of the operation package.

[0075] 5G private network\WIFI is used to realize communication between server and mobile terminal, and SQLite component is used in the system of mobile terminal to store web data and realize data caching, so that the system can still be operated when there is no 5G network\WIFI network.

[0076] When the mobile terminal module executes the digital procedure, it automatically checks the business model of the procedure file: 1. Whether the version of the procedure file is valid / consistent, 2. Whether the procedure is executed for the first time after the upgrade, 3. Whether the unit position described in the procedure file is consistent with the current position of the operator.

[0077] When the mobile terminal module executes the steps of the digital procedure, it automatically performs business model checks on the procedure steps: 1. Check the consistency between the executor's role and the role required by the procedure step, 2. Check the consistency between the current location of the mobile terminal / executor and the device location in the procedure step, 3. Check and remind the required input area in the procedure step, 4. Check and remind the device operation reading exceeds the threshold, 5. Reminder of abnormal trend of device operation reading, 6. Check and remind the skip step execution.

[0078] For example, when a user uses a mobile terminal to perform equipment operations according to the operating procedures on site, the system uses the 5G+ satellite positioning function of the mobile terminal to compare and check the location of the equipment that needs to be operated. When the system finds that the position deviation between the two exceeds the threshold, it reminds the user through the sound, vibration and display of alarm information of the mobile terminal, and prevents the user from further executing the operating procedures.

[0079] After multiple positions in the mobile module execute the same procedure in parallel, the system automatically merges the execution results of the procedure, including: automatic merging of results of different steps, and merging of the results of the same step with the last execution results.

[0080] In the procedure execution monitoring module, the main control operator can monitor the plan, on-site execution status, plan overview information of each procedure, and daily plan statistics of all procedures in real time through the large screen. The on-site execution status includes the executed steps, on-site personnel handover, suspension, termination, abnormal execution, on-site photography, etc. of the procedure execution; the daily plan statistics include the file type and position type of the procedure to be executed.

[0081] The completion and archiving module generates electronic completion and archiving records, which can automatically extract the contents of the work package to generate electronic completion and archiving records, and supports automatic electronic signatures. The preview and editing of electronic completion records allows users to preview and edit the contents of electronic completion records. Through the archiving electronic completion record submodule and the ECM system interface, the electronic completion records of the procedures and the archive metadata are automatically recorded in the ECM archive management system.

[0082] The completion archiving module automatically generates PDF records and automatically extracts personnel seals based on the operators (including step executors, guardians, procedure execution approvers, and procedure completion approvers) to complete the automatic electronic signature of the PDF.

[0083] The data maintenance module provides basic data maintenance for this system, including creating and maintaining formula libraries, associating formulas and parameters with digital operation procedures and procedure steps, and realizing automatic calculation of formula values ​​when the procedures are executed. This module supports the maintenance of various signatures, including personal signatures, anti-wrong interval signatures, etc.

[0084] The user-maintained display formulas and the corresponding system-calculable formulas are associated with the digital operation procedures, so that when the procedures are executed, the system automatically calculates the formula results based on the equipment readings in the procedure steps and fills them into the procedure steps.

[0085] Use the vue super flow component to edit and display the flowchart of the procedure file on the web page. Use the MathJax component to edit and display the formula on the web page. When creating a formula, fill in the formula corresponding to the formula, and use the formula to realize automatic calculation of the formula during the execution of the procedure.

[0091] S103: Preparation and issuance of procedure implementation plan

[0092] The procedure execution module is used to write the procedure execution plan on the PC. The procedure execution plan includes the procedure document, attachments to be referenced, procedure execution instructions, execution positions, planned start time, planned completion time, serial or parallel execution requirements, text annotations of steps in the digital procedure document, text notes, color annotations, whether the steps are executed, and step skipping locks.
