Description

Technical Field

[0001] The present invention relates to the technical field of digitalization of nuclear power plants, and more specifically, to a digital intelligent debugging system for nuclear power plants. Background Art

[0002] From the beginning of construction to the end of its life, a nuclear power plant usually needs to go through several stages, including feasibility study, design and procurement, equipment manufacturing, construction and installation, commissioning and startup, operation and decommissioning. Among them, commissioning and startup is a comprehensive inspection of the equipment, systems and structures after safe completion to ensure that the individual equipment and overall performance of the power plant meet the design requirements and relevant operating criteria. Design, manufacturing, civil engineering and installation defects in the engineering construction phase are mainly discovered or exposed through the commissioning link. If they can be properly resolved in the commissioning stage, it will lay a solid foundation for the long-term safe and stable operation of the power plant. At the same time, commissioning and startup is also the last process of nuclear power engineering construction, and it is an intersection connecting engineering and production. During this period, the types of professional operations, the total amount of engineering operations, and the complexity of the plan will reach a peak.

[0003] The existing debugging procedure system fails to fully implement the method of positive design integrity verification, which leads to the inability to fully guarantee the integrity of debugging verification when carrying out new reactor debugging work, and there is a possibility of missing verification of design functions, which in turn increases the potential risks of the unit in the in-service operation stage. At the same time, the debugging test activities are too dependent on the personal ability and quality of the debugging personnel, which makes the safety and quality level of nuclear power project debugging fluctuate due to factors such as differences in personal ability and quality, the timeliness of personnel training, the periodicity of project construction, and the variability of personnel configuration, and cannot be maintained at a high level. The manual working method leads to relatively low production efficiency in the debugging startup stage, such as the need to consume a lot of manpower and critical path duration to fill in and publish test reports. The static and isolated debugging data storage method can only support simple needs such as reference, and cannot achieve data efficiency, and loses the most important debugging process data. The quality and risk control of the debugging process rely solely on human defense, and the frequency, scope and accuracy are greatly limited, and gradually cannot meet the internal and external requirements for the first-time success rate of debugging, safety and quality level, etc. Summary of the invention

[0076] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0077] refer to Figure 1 , Figure 1 The principle block diagram of the digital intelligent debugging system for a nuclear power plant provided by the present invention is shown.

[0078] Specifically, Figure 1 As shown, the digital debugging system of the nuclear power plant includes: a nuclear power debugging data center 100 (Startup Data Center, SDC), a debugging navigation system 200 (Startup Navigation System, SNS) and a debugging test system 300 (Startup Testing System, STS).

[0079] Among them, the nuclear power commissioning data center 100 is used for sampling, analyzing, organizing, building a data base, displaying data, connecting and maintaining data for commissioning test data; the commissioning pilot system 200 is used for generating a pilot plan mechanism model, building a logical sequence of plan activities, building a commissioning pilot plan, distributing and managing the plan online, displaying commissioning plan information, managing joint commissioning plans, managing special plans, managing single system plans, managing micro plans, performing statistical analysis on the plan, and generating associated knowledge bases and model algorithms; the commissioning test system 300 is used for constructing commissioning program files, executing online tests, generating reports, digital archiving and transfer, digital quality control, integrating empirical business data, and managing process deviations based on the data of the nuclear power commissioning data center 100 and the information of the commissioning pilot system 200.

[0080] Furthermore, if Figure 1 As shown, the nuclear power plant digital intelligent commissioning system also includes a commissioning expert system 400 (Startup Expert System, SES). The commissioning expert system 400 is used to perform commissioning simulation deduction, early warning of the commissioning process, monitoring the health status of key commissioning equipment, and fault diagnosis.

[0081] The digital debugging system of the nuclear power plant of the present invention optimizes the construction of the traditional nuclear power debugging test program, further clarifies the relationship between design requirements, debugging methods, program planning, and file writing, ensures that the logic and mapping relationship are clearer and more organized, and proposes the probability of the debugging test unit (TU) on the basis of the traditional TP (Test Procedure) as the core element of the digital debugging test program. Compared with TP, TU can better establish a mapping relationship with the design function on the one hand, and on the other hand, it can undertake the "standardization" and "modularization" requirements proposed by the digital transformation of debugging, and plays a connecting role.

[0082] Specifically, in order to meet the requirements of debugging digital transformation, the present invention redesigns the content structure of TP / TU, as follows: Figure 2 As shown. It is mainly reflected in two parts: content writing and calculation configuration:

[0083] Content writing: The digital commissioning test program is based on the ideas of "standardization" and "modularization", and the content structure of the traditional nuclear power commissioning test program has been redesigned. The optimized program contains a total of nine main sections and four types of attachments. The content elements of each chapter and attachment have also been re-planned and typeset to ensure that they can be quickly and accurately structured when imported into STS (Startup Testing System, Commissioning Test System 300).

[0084] Calculation configuration: Calculation configuration needs to be completed in the STS system, which mainly includes global parameter configuration, data acquisition configuration, automatic calculation configuration, result analysis configuration, criterion curve configuration and other projects. By completing the above calculation configuration work, some or all operations can be automated and intelligent in the test execution link.

[0086] In an embodiment of the present invention, the data acquisition module is used to collect real-time data of the debugging test and store it in a database. Specifically, the nuclear power debugging data center 100 has the function of collecting real-time data of the debugging test and storing it in a real-time / historical database. Among them, the real-time data involved in the debugging stage can be divided into two categories according to the source of generation: one is the formal digital control platform of the nuclear power plant, which mainly uses the mobile data acquisition device arranged on site by the intelligent debugging platform to realize the data acquisition function; the other is various instruments and meters temporarily installed on site during the debugging stage, which mainly realize the data acquisition function through the full-range data acquisition device of the digital debugging system of the nuclear power plant provided by the embodiment of the present invention.

[0087] In an embodiment of the present invention, the text data parsing module is used to parse and structure the text data in the database to generate a digital debugging program or form a digital debugging pilot plan. Specifically, the nuclear power commissioning data center 100 has the function of importing, parsing and structuring text data, mainly including: ① parsing and structuring the WPS version debugging program file, and then building a digital debugging program; ② parsing and structuring the project version debugging plan file to form a digital debugging pilot plan.

[0088] In an embodiment of the present invention, the debugging data sorting module is used to parse and convert the debugging multi-source heterogeneous data in the database to generate a standard model of the debugging data. Specifically, by parsing and converting the debugging multi-source heterogeneous data, a standard model of the debugging data is constructed by classification. Metadata management is applied to realize data standardization requirements from multiple dimensions such as definition naming, data design, content format, and data exchange. At the same time, quality management methods are applied to the process of data storage and management to continuously improve the quality of debugging data governance (i.e., the quality of debugging data sorting).

[0089] In the embodiment of the present invention, the data base construction module is used to construct different types of debugging knowledge bases. Specifically, based on the in-depth analysis of debugging services and the design and development of software functions by the debugging pilot system 200, the debugging test system 300 and the debugging expert system 400, the present invention constructs various types of debugging knowledge bases to form a data base for the digital debugging system.

[0090] In the embodiment of the present invention, the data management and display module is used to visualize different types of data. Specifically, the nuclear power commissioning data center 100 establishes multiple types of data visualization interactive interfaces, including data point tables, trend views, statistical queries, comparative analysis, etc., for management and display of commissioning data to platform users.

[0091] In the embodiment of the present invention, the data connection and penetration module is used to connect and penetrate data based on the debugging business requirements. Specifically, based on the debugging business requirements, the present invention establishes data interfaces between the nuclear power debugging data center 100 and multiple business systems such as the PMS system (Project Management System) and the IMS system (Engineer Management Information System), thereby realizing data connection and penetration functions, avoiding data islands and duplicate construction, and improving the efficiency of data use.

[0092] In the embodiment of the present invention, the data asset construction module is used to construct the debugging data assets and interfaces; the data management and maintenance module is used to perform application management, authorization management, role management, and dictionary management and maintenance on the debugging data.

[0094] In an embodiment of the present invention, the pilot plan mechanism model generation module is used to construct an automatic generation mechanism model of a debugging plan. Specifically, two sets of automatic generation mechanism models of debugging plans are constructed through the pilot plan mechanism model generation module. The two sets of automatic generation mechanism models of debugging plans are respectively a plan generation mechanism model based on knowledge reasoning (pilot kernel 1) and a plan generation analysis model based on data drive (pilot kernel 2), which are used to support the deduction and automatic generation functions of the debugging plan.

[0095] In an embodiment of the present invention, the plan automatic generation module is used to automatically construct the logical sequence of the planned activities. Specifically, the plan automatic generation module enables the debugging navigation system 200 to have the deduction and automatic generation functions of a typical debugging plan by presetting the boundary parameters of the debugging plan. Furthermore, the plan automatic generation module can also automatically construct the logical sequence of the planned activities, and modulate the date and time of the planned activities and match the corresponding responsible personnel. At the same time, the debugging plan can be automatically updated to match the actual situation of the engineering site according to the changes in the parameters of the planned activities.

[0096] In the embodiment of the present invention, the plan rapid construction module is used to classify various construction activities in the debugging phase and construct digital activity units of the debugging plan. Specifically, the plan rapid construction module classifies various construction activities in the debugging phase to construct digital activity units of six types of debugging plans. At the same time, referring to the ideas of standardization and modularization, some commonly used activity units are classified and encapsulated into plan activity blocks. Based on the debugging domain graph technology, a debugging pilot plan can be quickly constructed.

[0097] In the embodiment of the present invention, the online plan distribution and management module is used to distribute and manage the debugging pilot plan online.

Compared with traditional plan management, its main feature is online real-time management.

[0098] In the embodiment of the present invention, the pilot plan overview module is used to display the logical relationship and execution status of the debugging plan.

[0101] In the embodiment of the present invention, the special plan management module is used to manage the special plan in the commissioning stage. Specifically, for the UP TO plan (a plan formulated to promote the start of a certain node; such as the UP TO cold test plan, the UP TO hot test plan... these are collectively referred to as the UP TO plan) and special plans in the nuclear power commissioning stage, the special plan management module realizes digital commissioning plan management with a time scale of days.

[0102] In the embodiment of the present invention, the single system plan management module is used to manage the debugging and testing activities corresponding to the nuclear power plant equipment system. Specifically, the joint debugging plan management and the special plan management are mainly aimed at various activities on the main critical path of debugging. In addition, the debugging pilot system 200 has also developed a single system plan management function, that is, through the single system plan management module, the nuclear power plant equipment system is taken as the object, and all corresponding debugging and testing activities are included in the management scope of the digital plan.

[0103] In the embodiment of the present invention, the micro-plan management module is used to manage the daily debugging work of the debugging personnel. Specifically, as the terminal extension of the single system plan management, the micro-plan management module can arrange and guide the daily debugging work of the debugging personnel.

[0104] In the embodiment of the present invention, the planned statistical analysis module is used to perform statistical analysis on the data of the pilot plan based on different dimensions and generate a statistical analysis report.

When constructing CFA, configuration operations are also required, including global parameter configuration, criterion curve configuration, process calculation configuration, etc., to achieve automation and intelligent functions such as automatic data acquisition, automatic result calculation, and automatic analysis and judgment in the test execution link.

[0109] In the embodiment of the present invention, the online test execution module is used to execute the commissioning test online based on the production data collected by the nuclear power commissioning data center 100.

In addition, it has the functions of revising and approving the test content.

[0110] In an embodiment of the present invention, a report automatic generation module is used to automatically generate a debugging test report according to a debugging test report template. Specifically, after the test is completed, the report automatic generation module can generate a debugging test report with one click according to the constructed debugging test report template. Among them, the debugging test report content includes at least a test form page, a cover page, a modification record page, a directory page, a TP summary, a TU text, and attachment content. The final approval of the debugging test report is implemented by initiating an audit process.

[0111] In an embodiment of the present invention, the digital archiving and handover module is used to generate a PDF master file for the approved and effective debugging test report and perform data encapsulation to construct a digital archiving and handover data package. Specifically, for the approved and effective TR report (Test Report), the digital archiving and handover module can validate the signed version of the PDF master file, and respectively encapsulate the attribute metadata and approval process data related to the TR to form an XML file and a PDF file to construct a digital archiving and handover data package.

[0114] In an embodiment of the present invention, the experience-business fusion module is used to classify and extract debugging experience data to form a structured debugging experience database, and to associate and fuse with business data to achieve real-time push.
