Technical Field

[0001] The invention relates to the technical field of nuclear power plant design, and in particular to an electromagnetic compatibility database system of a nuclear power plant. Background Art

[0002] The instrumentation and control system of a nuclear power plant is an important part of nuclear power. High integrity and reliable instrumentation and control (I&C) systems are essential for the safe operation of nuclear power plants. The development of I&C systems involves a large number of hardware devices, such as sensors, programmable logic controllers, hard-wired logic, wiring, monitoring and data acquisition equipment. Since the research on electromagnetic compatibility of nuclear power instrumentation and control systems in my country started late, the electromagnetic compatibility design and development process is still imperfect. In previous nuclear power designs, the electromagnetic compatibility requirements of different projects and different types of equipment were not unified, and the electromagnetic compatibility standard system was huge and highly professional. In the specific implementation process, there were certain differences in the understanding, requirements and management of electromagnetic compatibility data among various disciplines of design institutes and equipment suppliers. There was often a lack of standardized electromagnetic compatibility design guidance in the design process, and there were major deficiencies in the generation, application and management of design process data. In the electromagnetic compatibility design and development process of nuclear power plants, the entire life cycle from design input, design process to design output involves a large number of documents, models and data. The massive amount of data brings heavy work to the design and development personnel, and it is very easy to have quality problems due to omissions. At present, the data requirements in electromagnetic compatibility development are not standardized, the file management is not perfect, the content management is not unified, and only the equipment test standards and test reports are focused on. Most of them are collected and stored by different personnel, and there is no unified management and unified archiving, which brings great difficulties to the electromagnetic compatibility design and development work. At present, there is no function that can systematically solve the above data management problems.

[0003] The existing patent CN107992701A discloses an environmental simulation system based on digital technology, which includes an environmental simulation module: calling external excitation software to complete the construction of the simulation environment; a simulation output module: including a scene system and an analysis system, the scene system is used for simulation display, and the analysis system includes test process analysis, test result analysis, and test report generation; a test management platform: used to realize the execution management control of the environmental simulation module calling the external excitation software and the output result management of the simulation output module.

[0004] The existing patent CN102542343A discloses a unified shared data management platform and control method for an electric power system, including a number of electric power system devices and a simulation system, and also includes a database connected between the electric power system devices and the simulation system. The database collects the original parameters of the electric power system devices and converts them into calculation data files required by the simulation system and outputs them to the simulation system. The database includes a database body and a data maintenance module, a data backup module, an attachment upload and download module, a permission management module, a data status review module, an export module and a conversion module connected to the database body. The export module is connected to the conversion module. The method includes a data collection step, an export step and a conversion step.

[0005] In summary, the above two existing patents have not solved the problems of high labor input costs, low electromagnetic compatibility design efficiency and design reliability caused by non-standard data requirements, imperfect file management and inconsistent content management during the electromagnetic compatibility development process.

[0041] like Figure 1Schematic diagram of an electromagnetic compatibility database system of a nuclear power plant according to an embodiment of the present invention is shown in FIG. 1 , wherein the database system comprises: an information management database module 100 , a design guidance library module 200 , a simulation model library module 300 and a test database module 400 .

[0042] like Figure 1 As shown, the information management database module 100 is respectively connected to the design guidance library module 200, the simulation model library module 300, and the test database module 400, and is used to manage the electromagnetic compatibility design standards and design requirement documents in the nuclear power plant, and provide support for the design, analysis and calculation of the design guidance library module 200, the simulation model library module 300 and the test database module 400; the design guidance library module 200 is respectively connected to the simulation model library module 300 and the test database module 400, and is used to record the design information of the equipment and system in the nuclear power plant, and input the design information into the simulation model library module 300 and the test database module 400; the simulation model library module 300 is used to establish and store simulation model information in the electromagnetic compatibility database of the nuclear power plant based on the design information; the test database module 400 is used to perform statistical analysis and management on the electromagnetic compatibility test data of the nuclear power plant equipment.

[0043] Specifically, the information management database module 100 includes a standard management library module 101 and a design document library module 102. The standard management library module 101 is a basic module for electromagnetic compatibility design and development, and is used to structure and visualize the standard texts and standard limits used in nuclear power plant design. Figure 2 As shown, this embodiment classifies the standard text according to enterprise standards, national standards, international standards, industry standards, regional standards, and other standards, and enters, manages, and reads files in different formats such as PDF, Word, PPT, JPG, and PNG; for standard limits, the standard management library module 101 is used to plot the measurement limits in the form of charts and curves for the test limits, test levels, and frequency range data characteristics corresponding to the electromagnetic compatibility design indicators and test items, and also sorts out enterprise standards, national standards, international standards, industry standards, regional standards, and other standards, and uses them as basic data for simulation calculations in other simulation links, and as a basis for determining electromagnetic environment characteristics or sensitive thresholds.

[0044] The design document library module 102 can provide information input for the simulation model library module 300 and the test database module 400. The design document library module 102 and the simulation model library module 300 and the test database module 400 respectively record and store the electromagnetic compatibility-related data (including design, analysis and test data) of the entire life cycle of the equipment from different dimensions. Specifically, the design document library module 102 is used to manage the design institute documents and the equipment manufacturer documents respectively.

[0046] The design guidance library module 200 is an essential knowledge base for the feasibility demonstration stage in electromagnetic compatibility design, and can be used to guide the design and use of subsequent stages. From the perspective of the database, it provides the knowledge base for expert evaluation and interface calling functions for the simulation model library module 300 and the test database module 400. It is specifically used to provide design guidance for the electromagnetic compatibility design of nuclear power plants, classify and manage books, papers, and patents in Chinese and English, and input, manage, and read files in different formats such as PDF, Word, PPT, JPG, and PNG.

[0047] The test database module 400 includes a first test database submodule 401 and a second test database submodule 402. The first test database submodule 401 is used to manage the electromagnetic compatibility test data of the device during the development process; the second test database submodule 402 is used to perform statistical analysis on the electromagnetic compatibility test data after the device is finalized, and to classify, manage and evaluate the data generated before and after the electromagnetic compatibility test.

[0048] like Figure 5As shown, the first test database submodule 401 is used to classify and manage the electromagnetic compatibility test information of the nuclear power plant system and equipment according to the system test environment, system function, and system composition. The system test environment includes a semi-anechoic chamber, a full anechoic chamber, a shielded room, and a microwave anechoic chamber. System functions include conducted emission, radiated emission, conducted sensitivity, radiated sensitivity, and transient immunity. The system composition includes a measuring receiver, a low noise amplifier, an artificial network, a current probe, a receiving antenna, a signal source, a power amplifier, a coupling probe, and a coupling antenna. Depending on the equipment development process, the test object of the first test database submodule 401 can be an object independent of other modules, or it can be a design object that has been through a design document library or a simulation model library, or an object that has been designed through simulation calculation.

[0049] Furthermore, interfaces are provided between the first test database submodule 401, the second test database submodule 402 and the design guidance library module 200, and the expert / information guidance function of the design guidance library is called through the interfaces to achieve quality control and electromagnetic compatibility assessment during the electromagnetic compatibility design and development process. The electromagnetic compatibility assessment includes test result analysis, evaluation and utilization.

[0050] like Figure 6 As shown, the second test database submodule 402 is used to perform data statistics and analysis on the electromagnetic compatibility test results of the nuclear power plant system and equipment, and to classify and manage the data generated before and after the test. Performing data statistics and analysis on the test results includes: screening keywords such as equipment name, equipment signal, manufacturer, test item, whether it passes, etc., performing statistical analysis on the overall situation, obtaining corresponding statistical results, and completing a large amount of test data input, output, management, archiving, and analysis through the test database to manage and analyze the electromagnetic compatibility development of the system. The data generated before and after the test includes one or more of equipment information, test outline, test report, test data, and test result analysis content. Among them, the equipment information includes equipment name, equipment signal, manufacturer, and equipment function; the test outline and test report are entered, managed, and read in different formats of PDF, Word, Excel, PPT, JPG, and PNG files; the test data includes test items, test standards, test levels, frequency ranges, acceptance criteria, whether it passes, test time, test location, sensitive frequency points or over-standard frequency points, sensitive thresholds or over-standard amplitudes, sensitive margins or emission margins, and test curves.

[0051] The second test database submodule 402 provides customized electromagnetic compatibility test data evaluation functions based on data classification and screening, in view of the characteristics of the nuclear power industry, which has many engineering projects, equipment types and equipment quantities, including but not limited to electromagnetic compatibility test data evaluation functions based on equipment type screening, electromagnetic compatibility test data evaluation functions based on engineering project screening, electromagnetic compatibility test data evaluation functions based on test project screening, electromagnetic compatibility test data evaluation functions based on equipment suppliers, etc. The above management, statistics, and evaluation functions greatly improve the efficiency of massive data management of engineering projects and improve the reliability of electromagnetic compatibility design of nuclear power projects.

[0052] like Figure 7 As shown, the electromagnetic compatibility design and development process of a nuclear power plant is decomposed into three stages: design calculation, simulation analysis, and verification. Each stage generates a large amount of electromagnetic compatibility data, and a corresponding database is formulated according to the data characteristics of each stage. In the above embodiment, the information management database module 100, the design guidance library module 200, the simulation model library module 300, and the test database module 400 are all provided with corresponding data input interfaces and data output interfaces, and data interaction is performed with the electromagnetic compatibility auxiliary design software platform through the data input interface and the data output interface, so as to facilitate the operation of electromagnetic compatibility data, and cooperate with other electromagnetic compatibility design and development tools to apply electromagnetic compatibility data, and archive and manage data. Among them, the functions of the automatic input and output interfaces include that in the design stage, the present invention can cooperate with other electromagnetic compatibility design and development software, including automatically storing the design requirements at the system and equipment levels completed by the electromagnetic compatibility index decomposition software in the present invention, forming the electromagnetic compatibility design index technical scheme of the nuclear power plant; the cable coupling, cable radiation, and space coupling calculation results completed by the electromagnetic compatibility field line coupling calculation software are automatically stored in the electromagnetic compatibility database system, forming the electromagnetic compatibility field line coupling analysis report of the nuclear power plant.

[0053] In order to facilitate the use of designers in the design and development process, a very rich design and development interface is reserved, including manual input and output interfaces, as well as automatic software embedded input and output interfaces. Among them, the functions of the manual input and output interfaces include: design and development engineers can use the manual input interface to input classic expert knowledge, current electromagnetic compatibility standards, other model design schemes, other model simulation models, typical electromagnetic compatibility test systems, and other model electromagnetic compatibility data into various functional modules of the database system to support the electromagnetic compatibility demonstration, design, and verification of the model; at the same time, design and development engineers can use the manual output interface to export the improved classic expert knowledge, updated current electromagnetic compatibility standards, new model completed design schemes, new model completed simulation models, new model application electromagnetic compatibility test systems, and equipment-level electromagnetic compatibility data in an orderly manner, which is convenient for data management and document archiving and submission at the development process level.

[0054] During the verification stage, the electromagnetic compatibility database system of the present invention can also cooperate with other electromagnetic compatibility design management software, including automatically outputting compatible design standards, electromagnetic compatibility design indicators, and electromagnetic compatibility simulation analysis models to the electromagnetic compatibility design verification software to conduct an overall scoring evaluation of the plans made in the design stage and conduct a design effectiveness evaluation; in addition, the present invention can also automatically output various electromagnetic compatibility problems, electromagnetic compatibility test data, and electromagnetic compatibility test reports that arise in the design process to the electromagnetic compatibility quality management software to conduct an overall evaluation of the consistency and optimization rate of the design and verification stages, and form an electromagnetic compatibility design achievement rate analysis report.

[0055] The overall operation process is that in different development stages of electromagnetic compatibility design, designers operate the corresponding database modules through the operation interface and enter the corresponding data into the electromagnetic compatibility auxiliary design software platform to facilitate viewing, management and calling of data.

[0056] During the demonstration stage, it is necessary to collect and analyze a large amount of literature and standards, including classic design expert knowledge, current national standards / industry standards / international standards, to form a demonstration stage knowledge base; during the design stage, it is necessary to collect and analyze previous model system / equipment design schemes and other model system / equipment simulation models through a large amount of design documents to form a design stage knowledge base to support product design, and collect a large amount of models, data, and electromagnetic characteristics to support the analysis and call of various simulation software to form a simulation stage knowledge base; during the verification stage, it is necessary to archive and organize a large amount of tests and data to support the compliance verification of the pre-design process and facilitate data call by other design links to form a verification stage knowledge base.

[0057] Furthermore, the database system is designed with an external software interface, through which the electromagnetic simulation software and / or simulation model in the database system is called. The external software interface includes one or more of HFSS, FEKO, CST, CATIA, and AutoCAD.

[0058] The present invention integrates the above functional modules and completes the design of each submodule of the database system. The database system can be combined with the design and development process of the nuclear power plant and integrated into each level and each link of the nuclear power plant design. Figure 7 It can be seen that starting from the investigation and analysis, the nuclear power plant system design (design guidance library, standard management library, design document library), simulation (simulation model library), and testing (test system library, test database) are completed in sequence, and with the help of the electromagnetic compatibility database software module, the files, data, and reports are classified and stored.
