With the development of technology and the iteration of equipment, more and more nuclear power plants will use the digital instrument control system (DSC, Digital Instrument & Control System) of the nuclear power plant to manage the nuclear power plant. However, there are still many nuclear power plant instrument control systems with a relatively low degree of digitization. These nuclear power plant instrument control systems have been in operation for a long time, with serious board failures and aging problems. Moreover, due to product upgrades and replacements, many key devices have been phased out or have too high maintenance costs, so digital transformation and upgrading are required.

[0026] In the following description, specific details such as specific system architectures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0027] It should be understood that when used in the specification and appended claims of the present application, the term "comprising" indicates the presence of the described features, wholes, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their combinations.

[0028] It should also be understood that the term "and / or" used in the specification and appended claims of the present application refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] As used in the specification and appended claims of the present application, the term "if" can be interpreted as "when", "once", "in response to determining", or "in response to detecting" according to the context. Similarly, the phrase "if determined" or "if detecting [the described condition or event]" can be interpreted as meaning "once determined", "in response to determining", "once detecting [the described condition or event]", or "in response to detecting [the described condition or event]" according to the context.

[0030] In addition, in the description of the specification and appended claims of the present application, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0031] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that specific features, structures or characteristics described in connection with that embodiment are included in one or more embodiments of this application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0032] In currently operating nuclear power plants, due to the relatively long service time of some instrument and control systems, there are generally serious problems of board failures and aging. Moreover, because of product upgrades and replacements, many key devices have been phased out or have too high maintenance costs, making it difficult to transform and upgrade the instrument and control systems of nuclear power plants by means of board refurbishment or equipment replacement. At the same time, since the types of these nuclear power plant instrument and control systems are mainly analog types or analog plus semi-digital types, some instrument and control systems have independent process systems, complex control functions and special instrument and control equipment, making it difficult to be adapted to the current digital instrument and control systems (DSC, Digital Instrument & Control System) of nuclear power plants. In addition, due to the low digitalization level of the instrument and control systems of nuclear power plants, these instrument and control systems are gradually unable to meet the operation requirements of nuclear power plants. Therefore, it is necessary to digitally transform and upgrade the instrument and control systems of nuclear power plants. For example, the instrument and control system corresponding to the turbine-driven feed-water pump system (APP) of a nuclear power plant consists of a relay protection cabinet, assembled analog devices, and an early control system (such as the GEM80 control system). There is no corresponding dedicated system in the current digital instrument and control systems (DSC, Digital Instrument & Control System) of nuclear power plants.

[0033] When conducting a feasibility analysis of the digital transformation of the instrument and control systems of nuclear power plants, due to the lack of practical solutions and standards for the successful transformation and upgrade of operating nuclear power plants, it is only possible to conduct a feasibility analysis by means of manual analysis or by referring to the transformation projects and standards of relevant power plants (such as thermal power plants). However, due to the limitations of manual subjective experience and the fact that the transformation projects of relevant power plants are difficult to accurately adapt to nuclear power plants, the feasibility analysis of the digital transformation of the instrument and control systems of nuclear power plants is not accurate enough.

[0034] For example, the steam-driven feedwater pump system of a traditional thermal power plant, or small steam turbine, typically corresponds to the instrumentation and control system (I&C) of the micro-electro-hydraulic control system (MEH) supplied by the turbine manufacturer. These retrofits and upgrades are typically handled by the turbine manufacturer, who possess mature feasibility analysis, design, and project experience, and generally continue to use the MEH after retrofits. However, the MEH system for a thermal power plant differs significantly from the I&C system corresponding to the nuclear power plant's APP (for example, MEH retrofits and upgrades lack interfaces with reactor protection and control systems, and differ significantly in process control and system architecture), making it difficult to accurately adapt to the retrofit and upgrade of a nuclear power plant's I&C system.

[0035] Therefore, the above method has the problem that the feasibility analysis is not accurate enough when digitally transforming the instrumentation and control system of a nuclear power plant.

[0036] In order to improve the accuracy of liquid level control loop detection, the present application provides a feasibility analysis method for the digital transformation of a nuclear power plant's instrumentation and control system based on a disturbance test. In this method, the transformation standard is determined based on the system information of the instrumentation and control system to be transformed, and then the subsystems associated with the instrumentation and control system to be transformed are functionally analyzed based on the above-mentioned transformation standard. Based on the functional analysis results, a matching analysis is performed on the instrumentation and control system to be transformed and the preset digital system. Then, based on the matching analysis results, the system transformation scope of the instrumentation and control system to be transformed is determined. Finally, based on the above-mentioned transformation standard, the above-mentioned functional analysis results, the above-mentioned matching analysis results and the above-mentioned system transformation scope, the feasibility analysis results corresponding to the above-mentioned instrumentation and control system to be transformed are obtained.

[0037] Figure 1 A flowchart of a feasibility analysis method for digital transformation of a nuclear power plant instrumentation and control system provided in an embodiment of the present application is shown, and is described in detail as follows:

[0038] S11. Obtain system information of the instrumentation and control system to be modified, and determine modification standards based on the system information; the modification standards include information that needs to be followed when the instrumentation and control system to be modified is digitally modified.

[0039] The I&C systems to be upgraded refer to those in nuclear power plants that require digital upgrades, including analog or analog-plus-semi-digital I&C systems. For example, the I&C system to be upgraded may be the I&C system for a nuclear power plant's pneumatic feedwater pump system (APP), which includes relay protection cabinets, assembled analog components, and an earlier control system (e.g., the GEM80 control system). The system information refers to a collection of various hardware and software information reflecting the I&C system to be upgraded, including information such as its component equipment, system functional indicators, and operating status.

[0040] Specifically, assume that the instrument control system to be transformed is the instrument control system corresponding to the steam-driven feed water pump system of a nuclear power plant (hereinafter simply referred to as the APP instrument control system). The hardware and software information corresponding to the APP instrument control system can be obtained, including the information obtained from on-site research of the APP instrument control system, the information obtained from the analysis of the corresponding system drawings of the APP instrument control system, the information obtained from the analysis of the instrument control indicators of the APP instrument control system (i.e., the indicators reflecting the instrument control functions), etc. Then, a system database is established based on the above-mentioned hardware and software information. The above-mentioned system database can include a hardware database and a software database, such as an input / output device (I / O device) database and a local control device database, etc. Finally, based on the above-mentioned system database, a transformation standard that meets the digital transformation and upgrade of the APP instrument control system is established. The above-mentioned transformation standard includes industry standards, national standards, and international standards applicable to digital transformation, etc.

[0041] In the embodiment of the present application, a system database is constructed based on the system information of the above-mentioned instrument control system to be transformed, and based on the above-mentioned system database, a transformation standard applicable to the digital transformation and upgrade of the instrument control system to be transformed can be obtained.

[0042] S12. Perform function analysis on the above-mentioned instrument control system to be transformed according to the above-mentioned transformation standard to obtain a function analysis result; the above-mentioned function analysis result includes the function analysis results of the software system and / or hardware system corresponding to the above-mentioned instrument control system to be transformed.

[0043] Among them, the above-mentioned hardware system includes hardware devices such as a processor, instrument control devices (such as solenoid valves, control valves, and governors), cables, and device interfaces, and the above-mentioned software system includes software devices such as an operating system, a simulation system, and a system interface.

[0044] Specifically, after determining the above-mentioned transformation standard, the software system and / or hardware system corresponding to the instrument control system to be transformed can be first determined, and then the interface functions, software functions and / or hardware functions, system loop functions, etc. of the software system and / or hardware system are analyzed to obtain a function analysis result. Among them, the above-mentioned function analysis result is used to reflect whether the software system and / or hardware system corresponding to the instrument control system to be transformed meet the above-mentioned transformation standard. The above-mentioned function analysis result can include interfaces that meet the transformation standard, software parameters of hardware devices, system loops, etc. Of course, the above-mentioned function analysis result can also mark the interfaces, hardware devices, software parameters, system loops, etc. that do not meet the transformation standard in the instrument control system to be transformed.

[0045] For example, assume that the instrument control system to be transformed is the APP instrument control system. Then the corresponding function analysis may include at least one of the following: performing interface compatibility and security analysis on the interfaces of each analog component (such as relay protection cabinets, assembled analog devices, etc.) included in the APP instrument control system, performing function tests on the software functions and / or hardware functions of the early control system (such as the GEM80 control system) included in the APP instrument control system, and performing function tests on the loops included in the APP instrument control system, etc.

[0046] In the embodiments of the present application, by performing function tests on the software system and / or hardware system corresponding to the instrument control system to be transformed according to the above transformation criteria, it is possible to more accurately determine whether the software system and / or hardware system corresponding to the instrument control system to be transformed meets the above transformation criteria.

[0047] S13. According to the above function analysis results, perform matching analysis on the above instrument control system to be transformed and the preset digital system to obtain a matching analysis result; the above preset digital system is the fully digital management platform of the nuclear power plant expected to be obtained after the transformation of the above instrument control system to be transformed.

[0048] Among them, the above matching analysis refers to analyzing whether the above instrument control system to be transformed and the preset digital system can be matched, that is, analyzing whether the above preset digital system can implement the functions of the instrument control system to be transformed. The above fully digital management platform of the nuclear power plant can be a digital instrument control system (DSC, Digital Instrument & Control System) of the nuclear power plant. The above digital instrument control system of the nuclear power plant is a distributed control system based on computers and network communications. The digital instrument control system (DSC) of the nuclear power plant can realize the fully digital management of the instrument control system of the nuclear power plant, and its digitalization degree is higher than that of the instrument control system to be transformed.

[0049] Specifically, according to the above function analysis results, the method of simulation testing can be used to determine whether the above preset digital system can implement the interface functions, software functions and / or hardware functions, system loop functions, etc. of the software system and / or hardware system corresponding to the instrument control system to be transformed, and record the system functions that can be implemented and those that cannot be implemented to obtain the above matching analysis result. At the same time, it should be noted that according to the above matching analysis results, for the system functions that the preset digital system can implement, they can be directly applied to the preset digital system (for example, applied to the general function modules of the preset digital system), while for the system functions that the preset digital system cannot implement, dedicated hardware systems or software systems can be developed (for example, developing dedicated function modules in the preset digital system).

[0050] In the embodiments of the present application, by performing matching analysis on the to-be-transformed instrument control system and the preset digital system based on the above function analysis results, the matching and differences between the to-be-transformed instrument control system and the preset digital system can be better analyzed.

[0051] S14. Determine the system transformation scope of the to-be-transformed instrument control system according to the above matching analysis results.

[0052] Among them, the above system transformation scope includes the system functions in the to-be-transformed instrument control system that can be directly applied to the preset digital system, and the system functions in the to-be-transformed instrument control system that need to be transformed and upgraded to be applicable to the preset digital system. Of course, the above system transformation scope may also include the system functions in the to-be-transformed instrument control system that cannot be applied to the preset digital system.

[0053] For example, assuming that the to-be-transformed instrument control system is an APP instrument control system, the above system transformation scope may include the need to transform hardware devices, software configurations, interfaces, and circuits in the APP instrument control system.

[0054] In the embodiments of the present application, through the above system transformation scope, the transformation scope of the software system and / or hardware system corresponding to the to-be-transformed instrument control system can be better determined, improving the accuracy of the digital transformation and upgrade.

[0055] S15. Determine the feasibility analysis result of the to-be-transformed instrument control system according to the above transformation criteria, the above function analysis results, the above matching analysis results, and the above system transformation scope.

[0056] Specifically, the above feasibility analysis result may include the analysis process and result of feasibility. For example, a feasibility analysis report, a feasibility analysis document, etc. are generated by integrating the above transformation criteria, the above function analysis results, the above matching analysis results, and the above system transformation scope. Since the above feasibility analysis result contains the entire analysis process and all analysis results of the entire feasibility analysis, it can comprehensively guide the digital transformation and upgrade of the to-be-transformed instrument control system, thereby improving the accuracy of the feasibility analysis of the digital transformation of the nuclear power plant instrument control system. In addition, through the above feasibility analysis result (such as a feasibility analysis report, etc.), the consistency and standardization of the digital transformation and upgrade of the to-be-transformed instrument control system can also be improved.

[0057] In the embodiment of the present application, first, the transformation standard is determined according to the system information of the instrument control system to be transformed. Since the above transformation standard includes the information that needs to be followed when the instrument control system to be transformed is digitally transformed, the above transformation standard can be better adapted to the digital transformation of the nuclear power plant instrument control system. Then, the function of the instrument control system to be transformed is analyzed according to the above transformation standard, and the instrument control system to be transformed and the preset digital system are matched and analyzed according to the function analysis result. Then, the system transformation scope of the instrument control system to be transformed is determined according to the matching analysis result, which means that on the basis of following the above transformation standard, the functions of the software system and / or hardware system corresponding to the instrument control system to be transformed are fully considered, and the matching analysis result between the instrument control system to be transformed and the expected fully digital instrument control management platform of the nuclear power plant after transformation is considered, that is, the matching analysis result before and after the transformation of the instrument control system to be transformed can be reflected, so that the transformation scope of the above instrument control system to be transformed can be determined more accurately. Finally, according to the above transformation standard, the above function analysis result, the above matching analysis result and the above system transformation scope, a more comprehensive feasibility analysis result can be obtained, so the accuracy of the feasibility analysis of the digital transformation of the nuclear power plant instrument control system can be improved.

[0058] In another alternative embodiment of the present application, assuming that the instrument control system to be transformed is an APP instrument control system, since there is a lack of successful experience in the transformation of the APP instrument control system, in order to improve the comprehensiveness and accuracy of the transformation standard, before obtaining the system information of the instrument control system to be transformed and determining the transformation standard according to the above system information, it further includes:

[0059] Obtaining the reference instrument control system transformation information of the above instrument control system to be transformed; the above reference instrument control system transformation information at least includes the instrument control system transformation information of the thermal power plant.

[0060] Specifically, the above instrument control system transformation information of the thermal power plant may include the transformation standards of the thermal power plant (such as the industry standards, domestic standards, international standards, etc. for thermal power plant transformation), the transformation experience of thermal power units (such as the APP instrument control transformation experience of thermal power units), etc. Of course, the above reference instrument control system transformation information may also include information such as the design principles and design standards of newly built nuclear power units, which is not limited here. For example, the above reference instrument control system transformation information may also include the design experience and principles of the electric feed water pump system (APA) of newly built nuclear power units.

[0061] Correspondingly, in the case where the above reference instrument control system transformation information at least includes the instrument control system transformation information of the thermal power plant, the above determining the transformation standard according to the above system information includes:

[0062] Determining the above transformation standard according to the above reference instrument control system transformation information and the above system information.

[0063] In the embodiments of the present application, after obtaining the above-mentioned reference I&C system transformation information, a more comprehensive and accurate transformation standard can be obtained by combining the above-mentioned reference I&C system transformation information and system information. For example, after the digital transformation and upgrade of the APP I&C system, transformation standards suitable for the digital transformation and upgrade of the APP I&C system can be established or screened by combining information such as the design experience of the electric feed water pump system (APA) of newly built nuclear power units in China, the design and transformation experience of steam-driven feed water pump systems at home and abroad, and the national and industrial standards of domestic thermal power plants and nuclear power plants.

[0064] In some embodiments, the above-mentioned function analysis of the to-be-transformed I&C system is performed according to the above-mentioned transformation standard to obtain a function analysis result, including:

[0065] Determine the function analysis method corresponding to the subsystem associated with the to-be-transformed I&C system according to the above-mentioned transformation standard; the subsystems associated with the to-be-transformed I&C system include at least one of a nuclear safety system, a control system, and a circuit system;

[0066] Perform function analysis on the corresponding subsystem by using the determined function analysis method to obtain the above-mentioned function analysis result.

[0067] Among them, the above-mentioned nuclear safety system refers to a system that affects the safety of a nuclear power plant, including a 1E-class nuclear safety system (such as a reactor protection system (RPR), etc.), a nuclear safety-related system (such as a main feed water system (ARE) of a nuclear power plant, an auxiliary feed water system (ASG) of a nuclear power plant, etc.); the above-mentioned control system includes a control system unique to the to-be-transformed I&C system (such as the GEM80 control system, speed control system, overspeed protection system, etc. in the APP I&C system); the above-mentioned circuit system refers to a loop system composed of different I&C devices, cables, auxiliary devices, etc., and may include a loop system inside the to-be-transformed I&C system, and a loop system composed of the to-be-transformed I&C system and other subsystems of the nuclear power plant.

[0068] Specifically, assume that the to-be-transformed I&C system is the APP I&C system. Since the digital transformation of the APP I&C system is an overall digital transformation and upgrade plan, which includes multiple subsystems inside itself and will also be used in cooperation with other subsystems of the nuclear power plant, when performing the digital transformation of the APP I&C system, first determine all the subsystems associated with the APP I&C system, then determine the function analysis methods corresponding to different subsystems according to the above-mentioned transformation standard, and perform function analysis on the corresponding subsystems by using the determined function analysis methods, so as to determine whether each subsystem meets the above-mentioned transformation standard.

[0069] In the embodiment of the present application, by determining the functional analysis method corresponding to the subsystems associated with the instrumentation and control system to be modified through the above-mentioned modification standards, functional analysis of different subsystems can be performed more targeted, thereby improving the accuracy of functional analysis of different subsystems.

[0070] In some embodiments, in order to improve the accuracy of functional analysis, the functional analysis method may include at least one of the following: interface analysis, system analysis, and loop analysis. The functional analysis of the corresponding subsystem using the determined functional analysis method is performed to obtain the functional analysis results, including:

[0071] When the function analysis method includes an interface analysis method, performing interface security analysis on the subsystem according to the interface analysis method to obtain an interface function analysis result;

[0072] and / or,

[0073] When the functional analysis method includes a system analysis method, performing system parameter analysis on the subsystem according to the system analysis method to obtain a system functional analysis result;

[0074] and / or,

[0075] When the functional analysis method includes a loop analysis method, loop functional analysis is performed on the subsystem according to the loop analysis method to obtain a loop functional analysis result.

[0076] Specifically, when the above-mentioned function analysis method includes an interface analysis method, the above-mentioned interface analysis method includes at least one of the following: interface unit testing (i.e., testing and analyzing the independent functional modules of the interface), interface integration testing (i.e., testing and analyzing the interface after integration with components or interfaces of other subsystems), interface performance testing (i.e., testing and analyzing the performance of the interface under different loads), interface security testing (i.e., testing and analyzing the authentication, authorization and data encryption functions of the interface), interface compatibility testing (i.e., testing and analyzing the compatibility of the interface in different platforms and environments), etc. When the above-mentioned function analysis method includes a system analysis method, the above-mentioned system analysis method includes at least one of the following: hardware system parameter analysis (e.g., compatibility testing of hardware device parameters included in the hardware system, etc.), software system parameter analysis (e.g., compatibility testing of software parameters included in the software system, etc.). When the above-mentioned function analysis method includes a loop analysis method, loop analysis can be performed by manually establishing a loop analysis diagram, or by using a loop analysis method.

[0077] In the embodiment of the present application, the accuracy of the functional analysis can be improved by performing functional analysis on the subsystems associated with the instrumentation and control system to be modified through one or more of the above-mentioned interface analysis method, system analysis method, and loop analysis method.

[0078] In some embodiments, when the subsystem includes the nuclear safety system, performing interface security parsing on the subsystem according to the interface parsing method includes:

[0079] Determine the interfaces between the nuclear safety system and the instrumentation and control system to be modified; the interfaces include hardware interfaces and / or software interfaces;

[0080] Conduct security analysis on the above-mentioned related interfaces and the above-mentioned nuclear safety system.

[0081] Specifically, assuming that the instrumentation and control system to be modified is the APP instrumentation and control system, since the APP instrumentation and control system has interfaces (including hardware interfaces and software interfaces) with the above-mentioned nuclear safety systems (such as the reactor protection system (RPR), the nuclear power plant main feed water system (ARE), the nuclear power plant auxiliary feed water system (ASG), etc.), in order to avoid the impact of the APP instrumentation and control system modification on the nuclear safety system function, the hardware interfaces and / or software interfaces associated with the nuclear safety system and the above-mentioned instrumentation and control system to be modified can be first determined. Then, for the hardware interface, a safety analysis can be performed according to the preset hardware interface design principles (for example, determining whether the compatibility of the hardware interface design meets the preset safety standards). For the software interface, a safety analysis can be performed according to the preset software interface logic function design principles (for example, determining whether the design logic and design performance of the software interface meet the preset safety standards). Finally, based on the results of the safety analysis, the impact of each hardware interface and / or software interface on the nuclear safety system during the digital transformation of the APP instrumentation and control system can be determined. For example, the above-mentioned hardware interfaces and / or software interfaces can be ranked by a classification and rating method.

[0082] In the embodiment of the present application, by performing a security analysis on the interfaces associated with the nuclear safety system and the instrumentation and control system to be modified, the degree of impact of different interfaces on the nuclear safety system when the instrumentation and control system to be modified undergoes digital transformation can be better determined.

[0083] In some embodiments, when the subsystem includes the control system, performing system parameter analysis on the subsystem according to the system analysis method includes:

[0084] Determine the system parameters in the above control system; the above system parameters include hardware function parameters and software function parameters;

[0085] The preset digital system is used to perform parameter adaptation analysis on the system parameters, wherein the parameter adaptation analysis is used to determine whether the preset digital system can realize the functions of the system parameters.

[0086] Specifically, assuming the I&C system to be modified is an APP I&C system, the control system therein (e.g., the GEM80 control system) requires parameter adaptation analysis of its hardware and software functional parameters due to its long development time and significant differences from existing technologies. This involves determining whether the pre-set digital system can achieve the functions specified by these system parameters. Alternatively, a target parameter range can be determined using the pre-set digital system, and simulation analysis can be used to determine whether the hardware and software functional parameters are within the target parameter range. If so, it can be determined that the pre-set digital system can achieve the functions specified by these system parameters; otherwise, it cannot.

[0087] Among them, the above-mentioned hardware function parameters may include CPU scan cycle, instruction execution mode, card device driving capability, instruction action time, hardware setting parameters, analog accuracy, etc.; the above-mentioned software function parameters may include configuration function block parameters, proportional (P)-integral (I)-differential (D) (PID) parameters, time function block parameters, etc.

[0088] In some embodiments, the preset digital system includes a universal function module, which refers to a module that can carry the universal functions of the nuclear power plant instrumentation and control system. The universal function module may include a universal processor, a universal interface, a universal operating system, etc. Based on the above functional analysis results, a matching analysis is performed on the instrumentation and control system to be modified and the preset digital system, and the matching analysis results obtained include:

[0089] Determine the degree of compatibility between the instrumentation and control system to be modified and the general functional modules based on the above functional analysis results and the above modification standards;

[0090] The matching analysis result is determined based on the matching degree.

[0091] Specifically, multiple matching rules can be determined based on the above functional analysis results and the above transformation criteria. Then, according to the above matching rules, the hardware systems and software systems included in the to-be-transformed instrument control system and the general function modules are matched to obtain the matching degree of the above hardware systems and software systems. Among them, the above matching rules include matching rules for interfaces (hardware interfaces and / or software interfaces), matching rules for system parameters (hardware function parameters and software function parameters), matching rules for loops, etc. The above matching degree can include one of complete matching, incomplete matching, and complete non-matching. The above matching analysis results can include hardware systems and software systems with different matching degrees. For example, completely matched interfaces, hardware function parameters that are not matched at all, etc.

[0092] In the embodiments of the present application, the above functional analysis results and the above transformation criteria can be used to more comprehensively determine the matching rules, so as to perform matching analysis on the to-be-transformed instrument control system and the preset digital system according to the above matching rules, and obtain more accurate matching analysis results.

[0093] In some embodiments, the above preset digital system further includes a dedicated function module. The above dedicated function module refers to a module that can carry the functions of specific scenarios of the nuclear power plant instrument control system.

[0095] Specifically, after obtaining the above matching analysis results, the completely matched software systems and / or hardware systems can be divided into the above first system transformation scope according to the above matching analysis results, and the completely unmatched software systems and / or hardware systems can be divided into the above second system transformation scope, so as to more accurately determine the transformation scope of the to-be-transformed instrument control system. In addition, for software systems and / or hardware systems with incomplete matching, they can be assigned to the first system transformation scope or the second system transformation scope according to the difficulty of transformation, the priority of transformation, etc., so as to more flexibly determine the system transformation scope.

[0096] In another alternative embodiment of the present application, before determining the feasibility analysis result of the to-be-transformed instrument control system according to the above transformation criteria, the above functional analysis results, the above matching analysis results, and the above system transformation scope, it further includes:

[0100] Specifically, since the I&C system to be transformed may have been in use for a long time, in order to avoid problems such as transformation failure or inaccurate transformation caused by equipment aging, the equipment in the I&C system to be transformed (including the scope of system transformation and non-system transformation scope) can be analyzed and managed for aging according to a preset equipment aging management system, and the equipment that can no longer serve (such as cables, converters, etc.) can be identified and included in the above scope of system transformation. At the same time, there may be preset equipment in the above I&C system to be transformed that requires separate equipment optimization. The above equipment optimization analysis results include the optimization plan for the above preset equipment. For example, the above preset equipment can be Nuclear Power Plant Critical Component Management (CCM) equipment, that is, a single important non-redundant equipment related to the safety of the entire nuclear power plant, hereinafter simply referred to as CCM equipment. During the transformation, the equipment optimization analysis of the CCM equipment can be re-performed by manual analysis to determine the optimization plan for the CMM equipment, thereby improving the accuracy of the transformation and upgrade of the CCM equipment.

[0101] For example, the above preset equipment aging management system can compare the equipment in the I&C system to be transformed (including the scope of system transformation and non-system transformation scope) with the corresponding preset life threshold to obtain the corresponding life analysis results.

[0102] In the embodiments of the present application, after determining the scope of system transformation, adjusting the above scope of system transformation based on the results of life analysis, and performing equipment optimization analysis on the preset equipment within the adjusted scope of the above system transformation can improve the accuracy of the digital transformation of the I&C system to be transformed.

[0103] Correspondingly, after adjusting the above scope of system transformation, the feasibility analysis results of the above I&C system to be transformed are determined according to the above transformation criteria, the above function analysis results, the above matching analysis results, and the above scope of system transformation, including:

[0104] Determine the feasibility analysis results of the above I&C system to be transformed according to the above transformation criteria, the above function analysis results, the above matching analysis results, the adjusted above scope of system transformation, and the above equipment optimization analysis results.

[0105] Specifically, assume that the instrument control system to be transformed is the APP instrument control system. If the above feasibility analysis results include a feasibility analysis report, after adjusting the system transformation scope through life analysis and performing equipment optimization analysis on the preset equipment, by integrating the above transformation standards, function analysis results, matching analysis results, adjusted system transformation scope, and equipment optimization analysis results, a more comprehensive and accurate feasibility analysis report can be generated, improving the accuracy of the feasibility analysis of the digital transformation of the instrument control system to be transformed.

[0108] Specifically, assume that the above feasibility analysis results include a feasibility analysis report. Since the information included in the feasibility analysis report is more comprehensive, the software system and / or hardware system that needs to be subjected to function verification in the preset digital system can be determined according to the above feasibility analysis report, including the software system and / or hardware system corresponding to the general function module, and the software system and / or hardware system corresponding to the dedicated function module. Among them, the software system and / or hardware system corresponding to the general function module can be subjected to function test verification in the transformation factory in advance, and the software system and / or hardware system corresponding to the dedicated function module can be subjected to function test verification in the preset prototype, thereby advancing the verification of the digital transformation and upgrading, and saving the time for function verification after the transformation of the instrument control system to be transformed.

[0109] It should also be noted that the above verification results include the software system and / or hardware system with successful verification, and the software system and / or hardware system with failed verification. According to the software system and / or hardware system with failed verification, the above feasibility analysis results (such as the feasibility analysis report) can be readjusted, thereby continuously improving and perfecting the above feasibility analysis results, and further improving the accuracy of the feasibility analysis of the digital transformation of the nuclear power plant instrument control system.
