The execution sequence and execution logic between each step should be understood and inferred with reference to the content described in the embodiments.

[0065] As a representative of modern complex industrial systems, the operation of nuclear power plants involves a huge system scale, complex working conditions, and numerous equipment. During the startup and shutdown processes of the unit, the changes in equipment states and parameters require a large number of precise manual operations by operators, which not only increases the operation load and mental pressure but also easily leads to missed operations or incorrect operations, thus increasing the risk of the unit deviating from normal operation.

[0066] Traditional nuclear power operation methods rely on paper documents and nuclear power digital control systems. Although they can achieve basic operation control and status monitoring, there are obvious deficiencies in terms of automation and intelligence. With the development of technology, the application of automation and intelligence technologies in nuclear power plants has become an inevitable trend to reduce the workload of operators, standardize operation procedures, reduce the risk of misoperation, and improve the availability of unit operation.

[0067] Although certain progress has been made in the electronic and portable aspects of nuclear power plant operation procedures, these technical solutions still have many defects.

[0068] For example, some technical solutions mainly based on overall operation strategies convert them into executable operation procedures. However, this method requires a large number of basic documents and familiarity with the nuclear power plant system configuration, and is not applicable to nuclear power plants based on automatic start-stop technologies.

[0069] Some other technical solutions have achieved the portability of operation procedures, but mainly for on-site operation, maintenance, and repair personnel. For complex unit start-stop processes, the operator still needs to complete operations and monitoring in the main control room.

[0070] In addition, some technical solutions only provide methods for electronicizing operation procedures, unable to guide operators to apply and cooperate with the automatic start-stop system to complete unit automatic start-stop operations, and involving modifying the original procedures, which may bring conflicts in the user experience.

[0071] This application aims to solve at least one of the technical problems existing in the prior art. For this purpose, this application proposes a nuclear power plant start-stop method, its control system, electronic device, and storage medium, which can improve the availability of unit operation while reducing the risk of misoperation for the start-stop process of a nuclear power plant.

[0072] The following will be further described with reference to the accompanying drawings.

[0073] Referring to Figure 1 , the nuclear power plant start-stop method according to the first aspect embodiment of this application may include:

[0074] Step S101, obtaining an operation sequence procedure and a fault handling procedure, where the operation sequence procedure includes a sequential control step matching multiple controlled nuclear power equipment in the target nuclear power plant;

[0075] Step S102, in response to receiving a nuclear power plant start-stop instruction, sequentially performing sequential control operations on each controlled nuclear power equipment according to the sequential control steps in the operation sequence procedure;

[0076] Step S103, in response to detecting abnormal information of the nuclear power plant during the execution of the sequence control operation, stop the sequence control operation and record the current sequence control node, and according to the fault handling procedure, perform an abnormal feedback operation matching the abnormal information of the nuclear power plant;

[0077] Step S104, in response to detecting that the abnormal information of the nuclear power plant has disappeared, continue to execute the sequence control operation from the current sequence control node;

[0078] Step S105, in response to all the sequence control steps in the operation sequence procedure being executed, confirm that the target nuclear power plant is in a startup state or a shutdown state.

[0079] The nuclear power plant startup and shutdown method of the embodiments of the present application reduces the risk of misoperation while significantly improving the availability of the unit operation. Specifically, by automatically executing the sequence control operation, the need for manual operation is reduced, and the risk of misoperation is lowered; by real-time detecting and processing abnormal information, the safe operation of the unit under abnormal conditions is ensured; by continuing to execute the operation from the abnormal node, the downtime is reduced, and the availability of the unit operation is improved. These measures work together to provide a strong guarantee for the efficient and safe operation of the nuclear power plant.

[0080] In step S101 of some embodiments, obtain the operation sequence procedure and the fault handling procedure, where the operation sequence procedure includes the sequence control steps matching multiple controlled nuclear power equipment in the target nuclear power plant;

[0081] It should be noted that step S101 involves obtaining the operation sequence procedure and the fault handling procedure, where the operation sequence procedure includes the sequence control steps matching multiple controlled nuclear power equipment in the target nuclear power plant. This process is the basis of the nuclear power plant startup and shutdown method, ensuring the orderliness and accuracy of subsequent operations.

[0082] It should be pointed out that the operation sequence procedure is the core document in the nuclear power plant startup and shutdown process, which details the operation steps and sequence of each controlled nuclear power equipment. These operation sequence procedures are pre-compiled according to the specific design and operation requirements of the nuclear power plant, covering all stages from unit startup to shutdown. By obtaining these operation sequence procedures, the nuclear power plant startup and shutdown control system of the embodiments of the present application can execute operations according to the predetermined logical sequence, reducing the manual intervention of the operator and lowering the risk of misoperation. Among them, the sequence control steps in the operation sequence procedure correspond one by one to multiple controlled nuclear power equipment in the target nuclear power plant. This means that the operation steps and logic of each equipment have been detailedly planned and recorded. Through this matching, the nuclear power plant startup and shutdown control system of the embodiments of the present application can ensure that each equipment operates in the correct sequence and conditions during startup and shutdown. This precise matching not only improves the accuracy of the operation but also ensures the safe operation of the equipment.

[0083] In addition to running the sequence procedures, the embodiments of the present application also need to obtain the fault handling procedures. These fault handling procedures provide the methods and steps for handling abnormal situations. By integrating the fault handling procedures, the start-stop control system of the nuclear power plant in the embodiments of the present application can quickly respond when encountering abnormalities, stop the sequence control operation, and record the current sequence control nodes. This provides important information for subsequent fault troubleshooting and handling, ensuring the safe operation of the nuclear power plant under abnormal conditions.

[0084] By obtaining the operation sequence procedures and the fault handling procedures, the start-stop control system of the nuclear power plant in the embodiments of the present application can ensure the orderliness and accuracy of the operations during the start-up and shut-down processes of the nuclear power plant. The operation sequence procedures provide detailed operation steps, while the fault handling procedures ensure a quick response in case of abnormalities. This comprehensive procedure system not only improves the operation efficiency but also significantly reduces the risk of misoperation, providing a strong guarantee for the safe operation of the nuclear power plant.

[0085] In step S102 of some embodiments, in response to receiving a start-stop instruction for the nuclear power plant, sequential control operations are sequentially performed on each controlled nuclear power equipment according to the sequential control steps in the operation sequence procedures;

[0086] It should be noted that step S102 involves, in response to receiving a start-stop instruction for the nuclear power plant, sequentially performing sequential control operations on each controlled nuclear power equipment according to the sequential control steps in the operation sequence procedures. This process is the core of the start-stop method for the nuclear power plant, ensuring the automation and accuracy of the start-stop process.

[0087] It should be pointed out that when the nuclear power plant needs to start or stop, the operator can issue the corresponding start-stop instruction. This instruction can be manually input or triggered by automating the start-stop control system of the nuclear power plant in the embodiments of the present application. After receiving the start-stop instruction, the start-stop control system of the nuclear power plant in the embodiments of the present application can start the corresponding program and prepare to perform the start-stop operation.

[0088] In some embodiments of the present application, the operation sequence procedures can be pre-compiled, which include all necessary operation steps and logics during the start-up and shut-down processes of the nuclear power plant. These operation sequence procedures specify in detail the operation sequence and conditions of each controlled nuclear power equipment. The start-stop control system of the nuclear power plant in the embodiments of the present application can perform sequential control operations on each controlled nuclear power equipment according to these procedures. Among them, the sequential control operation means that the start-stop control system of the nuclear power plant in the embodiments of the present application controls each controlled nuclear power equipment in a predetermined order. The operation steps and logics of each equipment have been detailedly planned and recorded. The start-stop control system of the nuclear power plant in the embodiments of the present application can perform these operations sequentially to ensure that each controlled nuclear power equipment is started or stopped at the correct time and conditions.

[0089] By automatically executing sequential control operations, the nuclear power plant start-up and shut-down control system according to the embodiments of the present application can ensure the accuracy and consistency of the start-up and shut-down processes. The automatic operations reduce the manual intervention of operators and lower the risk of misoperations. Meanwhile, the nuclear power plant start-up and shut-down control system according to the embodiments of the present application can monitor the status and parameters of equipment in real time to ensure the accuracy and timeliness of each operation step.

[0090] During the execution of sequential control operations, the nuclear power plant start-up and shut-down control system according to the embodiments of the present application can monitor the status and parameters of equipment in real time. If any abnormal situation is detected, the nuclear power plant start-up and shut-down control system according to the embodiments of the present application can stop the operation and issue an alarm. This ensures the safety and reliability of the start-up and shut-down processes.

[0091] It should be understood that by responding to start-up and shut-down instructions and executing sequential control operations in accordance with the operation sequence regulations, the nuclear power plant start-up and shut-down control system according to the embodiments of the present application can ensure the automation and accuracy of the nuclear power plant start-up and shut-down processes. This process not only improves the operation efficiency but also significantly reduces the risk of misoperations, providing a strong guarantee for the safe operation of the nuclear power plant.

[0092] Referring to Figure 2 , according to some embodiments of the present application, the operation sequence regulations include multiple groups of sequential control steps corresponding to different functional requirements. Step S102 can sequentially perform sequential control operations on each controlled nuclear power equipment according to the sequential control steps in the operation sequence regulations, and may include:

[0093] Step S201, determining the inter-group arrangement order of each group of sequential control steps in the operation sequence regulations;

[0094] Step S202, traversing each group of sequential control steps based on the inter-group arrangement order to perform sequential control operations matching the corresponding functional requirements on each controlled nuclear power equipment.

[0095] In some embodiments, step S201 determines the inter-group arrangement order of each group of sequential control steps in the operation sequence regulations;

[0096] It should be noted that during the startup and shutdown process of a nuclear power plant, the step sequence groups with different functional requirements need to be executed in a certain logical order. For example, the startup of the safety system may need to be completed before the loading of the nuclear power plant startup and shutdown control system of the present application embodiment for fuel, and the adjustment of the cooling system may need to be carried out after the reactor reaches a stable state. By determining the correct inter-group arrangement order, it can be ensured that the step sequence groups of each functional requirement are executed at an appropriate time, thereby guaranteeing the safety and stability of the entire startup and shutdown process. The determination of this order is usually based on factors such as the design requirements, safety specifications, and operating experience of the nuclear power plant. When determining the inter-group arrangement order, the mutual dependencies and potential conflicts between the step sequence groups also need to be considered. For example, the execution of certain step sequence groups may require conditions or parameters provided by other step sequence groups, so it is necessary to ensure that these step sequence groups are arranged in the correct order. In addition, it is also necessary to avoid equipment damage or operating risks caused by improper arrangement of the step sequence groups.

[0097] In step S202 of some embodiments, based on the inter-group arrangement order, each group of sequential control steps is traversed to perform sequential control operations matching the corresponding functional requirements on each controlled nuclear power equipment.

[0098] It should be noted that after determining the inter-group arrangement order, the nuclear power plant startup and shutdown control system of the present application embodiment will traverse each group of sequential control steps based on this order. This means that the nuclear power plant startup and shutdown control system of the present application embodiment will sequentially access each sequential control step group and perform corresponding operations on each controlled nuclear power equipment according to the predetermined sequential control operations. During the traversal process, the nuclear power plant startup and shutdown control system of the present application embodiment will execute the sequential control operations matching the functional requirements of the current step group according to the functional requirements of the current step group. For example, when traversing to the safety system step group, the nuclear power plant startup and shutdown control system of the present application embodiment will start the relevant equipment of the safety system, such as the safety injection system, the containment ventilation system, etc. When traversing to the hot startup step group of the reactor, the nuclear power plant startup and shutdown control system of the present application embodiment can control operations such as power increase and coolant circulation of the reactor.

[0099] When traversing each group of sequential control steps, the nuclear power plant startup and shutdown control system of the present application embodiment can monitor the status and parameters of the equipment in real time and adjust the operation strategy according to the feedback information. If an abnormal situation occurs during the execution of a certain step group, the nuclear power plant startup and shutdown control system of the present application embodiment can immediately stop executing the current step group and trigger a fault handling mechanism. Once the abnormal situation is resolved, the nuclear power plant startup and shutdown control system of the present application embodiment can continue to execute the step group from the stopped position to ensure the integrity and continuity of the startup and shutdown process. In this way, the nuclear power plant startup and shutdown control system of the present application embodiment can flexibly respond to various possible situations and ensure the safe operation of the nuclear power plant during the startup and shutdown process.

[0100] Refer to Figure 3, according to some embodiments of the present application, the sequential control operation includes an automatic execution operation and a manual execution operation. Step S202 traverses each group of sequential control steps based on the inter-group arrangement order to perform a sequential control operation matching the corresponding functional requirements on each controlled nuclear power equipment, and may include:

[0101] Step S301, in response to the sequential control operation being an automatic execution operation, obtain an automatic control program based on the sequential control step, and perform an automatic execution operation on the controlled nuclear power equipment based on the automatic control program;

[0102] Step S302, in response to the sequential control operation being a manual execution operation, perform a first interactive prompt operation on the operator based on the sequential control step to prompt the operator to issue a first interactive operation instruction, and perform a manual execution operation according to the first interactive operation instruction.

[0103] In step S301 of some embodiments, in response to the sequential control operation being an automatic execution operation, obtain an automatic control program based on the sequential control step, and perform an automatic execution operation on the controlled nuclear power equipment based on the automatic control program;

[0104] It should be noted that when the sequential control operation is an automatic execution operation, the nuclear power plant start-stop control system of the embodiments of the present application can obtain the corresponding automatic control program based on the sequential control step, and perform an automatic execution operation on the controlled nuclear power equipment based on this program. Specifically, the nuclear power plant start-stop control system of the embodiments of the present application can automatically call a pre-set control program according to the current sequential control step to precisely control the equipment. For example, during the reactor startup process, the nuclear power plant start-stop control system of the embodiments of the present application can automatically adjust the flow rate and temperature of the coolant according to the sequential control step to ensure that the reactor gradually increases power in a safe state. This automatic execution operation can significantly improve the efficiency and accuracy of the start-stop process, reduce human intervention, and reduce the risk of misoperation.

[0105] In step S302 of some embodiments, in response to the sequential control operation being a manual execution operation, perform a first interactive prompt operation on the operator based on the sequential control step to prompt the operator to issue a first interactive operation instruction, and perform a manual execution operation according to the first interactive operation instruction.

[0106] It should be noted that when the sequence control operation is a manual execution operation, the nuclear power plant start-stop control system according to the embodiments of the present application can perform a first interactive prompt operation to the operator based on the sequence control step to prompt the operator to issue a first interactive operation instruction, and execute the manual execution operation according to this instruction. Specifically, the nuclear power plant start-stop control system according to the embodiments of the present application can issue a clear prompt to the operator according to the current sequence control step, informing the operator of the operation that needs to be performed. After receiving the prompt, the operator can issue corresponding operation instructions according to the actual situation, and the nuclear power plant start-stop control system according to the embodiments of the present application will execute the manual operation according to these instructions. For example, during the start-up or shutdown process of some key equipment, the nuclear power plant start-stop control system according to the embodiments of the present application can prompt the operator to perform a manual confirmation to ensure the safety and accuracy of the operation. This manual execution operation provides the operator with the necessary control power, enabling them to intervene when needed to ensure the safety and reliability of the start-stop process.

[0107] It should be understood that by combining the automatic execution operation and the manual execution operation, the nuclear power plant start-stop control system according to the embodiments of the present application can flexibly respond to different functional requirements and operation scenarios. In some scenarios that require high precision and high efficiency, the automatic execution operation can ensure the smooth progress of the start-stop process; while in some scenarios that require operator judgment and intervention, the manual execution operation provides the necessary flexibility and safety. This comprehensive execution method not only improves the efficiency of the start-stop process but also ensures the safety and reliability of the entire process.

[0108] Referring to Figure 4 , according to some embodiments of the present application, step S302 of performing a first interactive prompt operation to the operator based on the sequence control step to prompt the operator to issue a first interactive operation instruction and execute the manual execution operation according to the first interactive operation instruction may include:

[0109] Step S401, when the manual execution operation is an authorized operation type, perform an authorization prompt operation to the administrator based on the sequence control step to prompt the administrator to issue an authorization permission instruction;

[0110] Step S402, in response to receiving the authorization permission instruction, perform a first interactive prompt operation to the operator according to the sequence control step and the authorization permission instruction to prompt the operator to issue a first interactive operation instruction, and execute the manual execution operation according to the first interactive operation instruction.

[0111] Step S401 of some embodiments, when the manual execution operation is an authorized operation type, perform an authorization prompt operation to the administrator based on the sequence control step to prompt the administrator to issue an authorization permission instruction;

[0112] It should be noted that when the manual operation belongs to the authorized operation type, the nuclear power plant start-stop control system according to the embodiments of the present application can perform an authorization prompt operation on the administrator based on the sequence control steps. This step is to ensure that critical operations are properly approved and supervised. The nuclear power plant start-stop control system according to the embodiments of the present application can issue a clear prompt to the administrator according to the current sequence control steps, informing the operations that need to be performed. After receiving the prompt, the administrator can issue an authorization permission instruction according to the actual situation. This mechanism ensures that only authorized operations can be executed, thereby improving the safety and reliability of the operations.

[0113] In step S402 of some embodiments, in response to receiving the authorization permission instruction, a first interactive prompt operation is performed on the operator according to the sequence control steps and the authorization permission instruction, to prompt the operator to issue a first interactive operation instruction, and the manual execution operation is performed according to the first interactive operation instruction.

[0114] It should be noted that once the nuclear power plant start-stop control system according to the embodiments of the present application receives the authorization permission instruction from the administrator, it can perform a first interactive prompt operation on the operator according to the sequence control steps and the instruction. This step ensures that the operator has received the necessary authorization and guidance before performing the manual operation. The nuclear power plant start-stop control system according to the embodiments of the present application can issue a clear prompt to the operator, informing the operations that need to be performed. After receiving the prompt, the operator can issue a first interactive operation instruction according to the actual situation. The nuclear power plant start-stop control system according to the embodiments of the present application performs the manual execution operation according to these instructions, ensuring the accuracy and safety of the operation.

[0115] Through the steps shown in step S401 to step S402 above, the nuclear power plant start-stop control system according to the embodiments of the present application not only ensures that critical operations are properly authorized and supervised, but also improves the safety and accuracy of the operations. In the case of authorized operation types, the participation of the administrator ensures the compliance and safety of the operations. At the same time, the operator receives clear prompts and guidance before performing the manual operation, reducing the risk of misoperation. This mechanism is particularly important during the start-stop process of the nuclear power plant, ensuring the smooth progress of critical operations.

[0116] It should be understood that this authorization-based operation mechanism enables the nuclear power plant start-stop control system according to the embodiments of the present application to flexibly respond to different operation requirements. In scenarios that require high safety and compliance, the authorization of the administrator ensures the rigor of the operations. While in scenarios that require the operator's judgment and intervention, the interactive prompts provided by the nuclear power plant start-stop control system according to the embodiments of the present application ensure the accuracy and timeliness of the operations. This flexible operation mechanism not only improves the efficiency of the start-stop process, but also ensures the safety and reliability of the entire process.

[0117] Refer to Figure 5, according to some embodiments of the present application, step S202 traverses each sequence control step in the order of arrangement between groups to perform sequential control operations matching the corresponding functional requirements on each controlled nuclear power equipment, and may include:

[0118] Step S501, for each sequence control step in the operation sequence regulation, when the sequential control operation corresponding to the sequence control step has been executed, configure a corresponding step completion identifier for the sequence control step;

[0119] Step S502, in response to receiving a step progress query instruction, generate step progress representation information according to each sequence control step in the operation sequence regulation that is configured with a step completion identifier.

[0120] In step S501 of some embodiments, for each sequence control step in the operation sequence regulation, when the sequential control operation corresponding to the sequence control step has been executed, configure a corresponding step completion identifier for the sequence control step;

[0121] It should be noted that during the execution of the sequential control operation, the nuclear power plant start-stop control system according to the embodiments of the present application can monitor each sequence control step in the operation sequence regulation. When the sequential control operation corresponding to a certain sequence control step has been executed, the nuclear power plant start-stop control system according to the embodiments of the present application can configure a corresponding step completion identifier for the sequence control step. The function of this identifier is to clearly indicate that the step has been completed and provide a reference for subsequent operations. For example, during the reactor startup process, when the nuclear power plant start-stop control system according to the embodiments of the present application has completed the startup operation according to the predetermined steps, the nuclear power plant start-stop control system according to the embodiments of the present application can configure a completion identifier for this step to indicate that this part of the operation has been successfully executed. This identifier mechanism not only helps the operator to understand the progress of the start-stop process in real time, but also provides an important basis for the automated management of the nuclear power plant start-stop control system according to the embodiments of the present application.

[0122] In step S502 of some embodiments, in response to receiving a step progress query instruction, generate step progress representation information according to each sequence control step in the operation sequence regulation that is configured with a step completion identifier.

[0123] It should be noted that when the nuclear power plant startup and shutdown control system according to the embodiments of the present application receives a step sequence progress query instruction, it can generate step sequence progress representation information based on each sequential control step in the operation sequence regulation that has been configured with a step completion flag. This information is usually presented in a visual form, such as a progress bar, list, or chart, enabling the operator to intuitively understand the progress of the entire startup and shutdown process. For example, the operator can view the completion status of each step and the overall progress of the entire startup and shutdown process through the interface of the nuclear power plant startup and shutdown control system according to the embodiments of the present application. Such progress representation information not only improves the transparency of the operation but also provides timely feedback to the operator, enabling necessary adjustments and interventions according to the actual situation.

[0124] Referring to Figure 6 , according to some embodiments of the present application, step S102 may include, in sequence, performing sequential control operations on each controlled nuclear power equipment according to the sequential control steps in the operation sequence regulation:

[0125] Step S601, for the controlled nuclear power equipment of the digital quantity control type, performing an equipment opening operation or an equipment closing operation on the controlled nuclear power equipment based on the sequential control step;

[0126] Step S602, for the controlled nuclear power equipment of the analog quantity control type, setting the controlled nuclear power equipment to the automatic mode based on the sequential control step, so that the controlled nuclear power equipment performs analog quantity adaptive control for the corresponding analog quantity;

[0127] Step S603, for the controlled nuclear power equipment of the information collection type, controlling the controlled nuclear power equipment to perform data collection operations based on the sequential control step.

[0128] In step S601 of some embodiments, for the controlled nuclear power equipment of the digital quantity control type, performing an equipment opening operation or an equipment closing operation on the controlled nuclear power equipment based on the sequential control step;

[0129] It should be noted that for the controlled nuclear power equipment of the digital quantity control type, the nuclear power plant startup and shutdown control system according to the embodiments of the present application can perform an equipment opening operation or an equipment closing operation on these equipment based on the sequential control step. Digital quantity control type equipment usually refers to those equipment with only two states of on and off, such as circuit breakers, disconnectors, etc. During the startup and shutdown process of a nuclear power plant, the correct operation of these equipment is crucial. For example, during the reactor startup process, the nuclear power plant startup and shutdown control system according to the embodiments of the present application can sequentially open the relevant circuit breakers according to the sequential control step to ensure normal power supply; during the shutdown process, these circuit breakers can be sequentially closed to ensure equipment safety. By automatically performing these operations, the nuclear power plant startup and shutdown control system according to the embodiments of the present application can ensure that each equipment is opened or closed at the correct time, thereby improving the efficiency and safety of the startup and shutdown process.

[0130] In step S602 of some embodiments, for controlled nuclear power equipment of the analog quantity control type, based on the sequence control steps, the controlled nuclear power equipment is set to the automatic mode, so that the controlled nuclear power equipment performs analog quantity adaptive control for the corresponding analog quantity.

[0131] It should be noted that for controlled nuclear power equipment of the analog quantity control type, the nuclear power plant start-stop control system of the embodiments of the present application can set these devices to the automatic mode based on the sequence control steps, so that the devices can perform adaptive control for the corresponding analog quantity. Analog quantity control type devices usually refer to those devices that need to adjust continuous variables, such as pumps, valves, etc. In the automatic mode, these devices can automatically adjust their outputs according to real-time operating parameters to meet the operating requirements of the nuclear power plant. For example, in the reactor cooling system, the nuclear power plant start-stop control system of the embodiments of the present application can set the cooling pump to the automatic mode according to the sequence control steps, so that it can automatically adjust the pump speed according to the temperature and flow rate of the cooling water to ensure that the reactor operates within a safe temperature range. This kind of adaptive control can improve the operating efficiency of the device, reduce human intervention, and reduce the risk of misoperation.

[0132] In step S603 of some embodiments, for controlled nuclear power equipment of the information collection type, based on the sequence control steps, the controlled nuclear power equipment is controlled to perform data collection operations.

[0133] It should be noted that for controlled nuclear power equipment of the information collection type, the nuclear power plant start-stop control system of the embodiments of the present application can control these devices to perform data collection operations based on the sequence control steps. Information collection type devices usually refer to those devices used to monitor the operating status of the nuclear power plant, such as sensors, monitoring instruments, etc. During the start-stop process of the nuclear power plant, these devices can collect various operating parameters in real time, such as temperature, pressure, flow rate, etc., and transmit the data to the nuclear power plant start-stop control system of the embodiments of the present application. The nuclear power plant start-stop control system of the embodiments of the present application can perform real-time monitoring and analysis based on these data to ensure that the operating status of the nuclear power plant is always within a safe range. For example, during the reactor startup process, the nuclear power plant start-stop control system of the embodiments of the present application can control the temperature sensor to collect the temperature data of the reactor core according to the sequence control steps, and transmit these data to the nuclear power plant start-stop control system of the embodiments of the present application, so that the operator can understand the temperature change of the reactor in real time. This kind of real-time data collection can improve the operating transparency of the nuclear power plant and provide timely decision-making basis for the operator.

[0134] In step S103 of some embodiments, in response to detecting abnormal information of the nuclear power plant during the execution of the sequence control operation, the sequence control operation is stopped and the current sequence control node is recorded, and according to the fault handling procedure, an abnormal feedback operation matching the abnormal information of the nuclear power plant is executed;

[0135] It should be noted that step S103 involves detecting abnormal information of the nuclear power plant during the execution of the sequence control operation, stopping the sequence control operation and recording the current sequence control node, and then performing a matching abnormal feedback operation according to the fault handling procedure. This process is the key to ensuring that the nuclear power plant can safely and effectively handle problems when encountering abnormal situations during startup and shutdown.

[0136] It should be pointed out that during the execution of the sequence control operation, the nuclear power plant startup and shutdown control system of the embodiment of the present application can monitor various operating parameters and equipment statuses of the nuclear power plant in real time. If the nuclear power plant startup and shutdown control system of the embodiment of the present application detects any abnormal information through sensing components such as sensors, such as equipment failures, parameters exceeding the normal range, or system error reports, it can trigger an abnormal handling mechanism. This real-time monitoring ensures that the nuclear power plant startup and shutdown control system of the embodiment of the present application can quickly respond to any potential problems, thereby preventing the abnormal situation from deteriorating further. Once abnormal information is detected, the nuclear power plant startup and shutdown control system of the embodiment of the present application can stop the current sequence control operation. This measure is to prevent the abnormal situation from further expanding when continuing to execute the operation, ensuring the safe operation of the nuclear power plant. Stopping the sequence control operation is an emergency measure aimed at protecting the safety of equipment and personnel, and at the same time providing a stable state for subsequent fault handling.

[0137] On the other hand, while stopping the sequence control operation, the nuclear power plant startup and shutdown control system of the embodiment of the present application can record the current sequence control node. This record is very important because it provides key information for subsequent fault handling and operation recovery. By recording the current node, the nuclear power plant startup and shutdown control system of the embodiment of the present application can know which step the operation has reached when the abnormality occurs, so that it can continue to execute the operation from the correct position after the fault handling is completed.

[0138] It should be clear that according to the fault handling procedure, the nuclear power plant startup and shutdown control system of the embodiment of the present application can perform abnormal feedback operations that match the detected abnormal information. These operations may include isolating the faulty equipment, switching to the standby system, adjusting the operating parameters, or notifying the maintenance personnel, etc. The purpose of the abnormal feedback operation is to resolve the abnormal problem as soon as possible and restore the normal operating state of the system. These operations are predefined to ensure that actions can be taken quickly and effectively in case of an abnormality.

[0139] It should be understood that through the above steps, the start-up and shut-down control system of the nuclear power plant according to the embodiments of the present application can not only ensure safety in abnormal situations, but also improve the efficiency of handling abnormalities. Recording the current sequential control node and performing the matching abnormal feedback operation enables the start-up and shut-down control system of the nuclear power plant according to the embodiments of the present application to quickly resume normal operation after fault handling, reducing the downtime and operation risks. This mechanism is an indispensable part of the start-up and shut-down process of the nuclear power plant, providing an important guarantee for the safe and reliable operation of the nuclear power plant.

[0140] Referring to Figure 7 , according to some embodiments of the present application, step S103, in response to detecting abnormal information of the nuclear power plant during the execution of the sequential control operation, stops the sequential control operation and records the current sequential control node, and according to the fault handling procedure, performs an abnormal feedback operation matching the abnormal information of the nuclear power plant, may include:

[0141] Step S701, in response to detecting abnormal information of the nuclear power plant during the execution of the sequential control operation, stops the sequential control operation and records the current sequential control node;

[0142] Step S702, in the case where the abnormal information of the nuclear power plant includes abnormal equipment parameter information, performs an abnormal feedback operation according to the fault handling procedure matching the abnormal equipment parameter information;

[0143] Step S703, in the case where the abnormal information of the nuclear power plant includes abnormal unit operation information, performs an abnormal feedback operation according to the fault handling procedure matching the abnormal unit operation information.

[0144] Step S701 of some embodiments, in response to detecting abnormal information of the nuclear power plant during the execution of the sequential control operation, stops the sequential control operation and records the current sequential control node;

[0145] It should be noted that when abnormal information of the nuclear power plant is detected during the execution of the sequential control operation, the start-up and shut-down control system of the nuclear power plant according to the embodiments of the present application can immediately stop the current sequential control operation and record the current sequential control node. This mechanism ensures that in abnormal situations, the start-up and shut-down control system of the nuclear power plant according to the embodiments of the present application can quickly respond and prevent the abnormal situation from deteriorating further. Recording the current sequential control node provides important information for subsequent fault handling, enabling the start-up and shut-down control system of the nuclear power plant according to the embodiments of the present application to continue operating from the correct position after the fault handling is completed. For example, if abnormal cooling system is detected during the reactor startup process, the start-up and shut-down control system of the nuclear power plant according to the embodiments of the present application can immediately stop the startup operation and record the current startup step for subsequent targeted fault handling.

[0146] In step S702 of some embodiments, when the abnormal information of the nuclear power plant includes equipment parameter abnormal information, an abnormal feedback operation is performed according to the fault handling procedure matched to the equipment parameter abnormal information;

[0147] It should be noted that if the detected abnormal information of the nuclear power plant includes equipment parameter abnormal information, the nuclear power plant start-stop control system according to the embodiments of the present application can perform an abnormal feedback operation according to the fault handling procedure matched to the abnormal information. The abnormal equipment parameters may involve key parameters such as temperature, pressure, and flow exceeding the normal range. The nuclear power plant start-stop control system according to the embodiments of the present application can take corresponding measures according to the preset fault handling procedure, such as adjusting the equipment operation state, switching to standby equipment, or performing an emergency shutdown. For example, if it is detected that the temperature of the reactor coolant rises abnormally, the nuclear power plant start-stop control system according to the embodiments of the present application can automatically adjust the coolant flow or switch to a standby cooling system according to the fault handling procedure to ensure the safe operation of the reactor.

[0148] In step S703 of some embodiments, when the abnormal information of the nuclear power plant includes unit operation abnormal information, an abnormal feedback operation is performed according to the fault handling procedure matched to the unit operation abnormal information.

[0149] It should be noted that if the detected abnormal information of the nuclear power plant includes unit operation abnormal information, the nuclear power plant start-stop control system according to the embodiments of the present application can perform an abnormal feedback operation according to the fault handling procedure matched to the abnormal information. The abnormal unit operation may involve errors in the operation process or failure of equipment operation. The nuclear power plant start-stop control system according to the embodiments of the present application can provide corresponding operation guidance or automatically take corrective measures according to the fault handling procedure. For example, if it is detected that a key equipment fails to start successfully during the unit startup process, the nuclear power plant start-stop control system according to the embodiments of the present application can prompt the operator to perform manual intervention or automatically attempt to restart the equipment according to the fault handling procedure to ensure the smooth progress of the startup process.

[0150] Refer to Figure 8 , according to some embodiments of the present application, the fault handling procedure includes at least one fault handling step. Step S103, in response to detecting abnormal information of the nuclear power plant during the execution of the sequence control operation, stops the sequence control operation and records the current sequence control node, and performs an abnormal feedback operation matched to the abnormal information of the nuclear power plant according to the fault handling procedure, which may include:

[0151] Step S801, in response to detecting abnormal information of the nuclear power plant during the execution of the sequence control operation, stops the sequence control operation and records the current sequence control node;

[0152] Step S802, in response to the fault handling step sequence being an automatic fault handling step sequence, load the first type of preset response program that matches the automatic fault handling step sequence to perform an abnormal feedback operation;

[0153] Step S803, in response to the fault handling step sequence being a manual fault handling step sequence, load the preset interaction program that matches the manual fault handling step sequence, perform a second interaction prompt operation on the operator to prompt the operator to issue a second interaction operation instruction to perform an abnormal feedback operation.

[0154] In step S801 of some embodiments, in response to detecting abnormal information of the nuclear power plant during the execution of the sequence control operation, stop the sequence control operation and record the current sequence control node;

[0155] It should be noted that when abnormal information of the nuclear power plant is detected during the execution of the sequence control operation, the embodiments of the present application can immediately stop the current sequence control operation and record the current sequence control node. This mechanism ensures that in the event of an abnormality, the embodiments of the present application can react quickly to prevent the abnormal situation from deteriorating further. Recording the current sequence control node provides important information for subsequent fault handling, enabling the embodiments of the present application to continue operating from the correct position after the fault handling is completed. For example, if an abnormality in the cooling system is detected during the reactor startup process, the embodiments of the present application can immediately stop the startup operation and record the current startup step for subsequent targeted fault handling.

[0156] In step S802 of some embodiments, in response to the fault handling step sequence being an automatic fault handling step sequence, load the first type of preset response program that matches the automatic fault handling step sequence to perform an abnormal feedback operation;

[0157] It should be noted that if the fault handling step sequence is an automatic fault handling step sequence, the embodiments of the present application can load the first type of preset response program that matches this step sequence to perform an abnormal feedback operation. These preset response programs are preset according to common fault types and handling methods, and can automatically perform a series of operations to cope with abnormal situations. For example, if abnormal device parameters are detected, the embodiments of the present application can automatically adjust the device operating state or switch to a standby device to ensure the safe operation of the nuclear power plant. This automatic processing mechanism can quickly respond to abnormal situations, reduce human intervention, and improve the efficiency and accuracy of fault handling.

[0158] In step S803 of some embodiments, in response to the fault handling step sequence being a manual fault handling step sequence, load the preset interaction program that matches the manual fault handling step sequence, perform a second interaction prompt operation on the operator to prompt the operator to issue a second interaction operation instruction to perform an abnormal feedback operation.

[0159] It should be noted that if the fault handling procedure is a manual fault handling procedure, the nuclear power plant start-stop control system according to the embodiments of the present application can load a preset interaction program that matches this procedure, and perform a second interactive prompt operation to the operator to prompt the operator to issue a second interactive operation instruction, so as to perform an abnormal feedback operation. In this case, the nuclear power plant start-stop control system according to the embodiments of the present application can provide detailed fault information and handling suggestions, and the operator can perform manual operations based on this information and suggestions. For example, if it is detected that the unit operation is abnormal, the nuclear power plant start-stop control system according to the embodiments of the present application can prompt the operator to perform manual intervention, such as adjusting the operation process or checking the equipment status. This manual handling mechanism ensures that in complex or special situations, the operator can handle flexibly according to the actual situation to ensure the safe operation of the nuclear power plant.

[0160] Referring to Figure 9 , according to some embodiments of the present application, the fault handling regulation further includes a backup handling procedure corresponding to each manual fault handling procedure. Before step S803 loads a preset interaction program that matches the manual fault handling procedure and performs a second interactive prompt operation to the operator, it may further include:

[0161] Step S901, in response to the nuclear power plant abnormal information including human-machine interaction abnormal information, according to the backup handling procedure corresponding to the manual fault handling procedure, and determine a second type of preset response program that matches the backup handling procedure;

[0162] Step S902, load a second type of preset response program that matches the backup handling procedure to perform an abnormal feedback operation.

[0163] In step S901 of some embodiments, in response to the nuclear power plant abnormal information including human-machine interaction abnormal information, according to the backup handling procedure corresponding to the manual fault handling procedure, and determine a second type of preset response program that matches the backup handling procedure;

[0164] It should be noted that if the abnormal information of the nuclear power plant includes human-machine interaction abnormal information, the nuclear power plant start-stop control system according to the embodiments of the present application can determine a second type of preset response program that matches the backup handling procedure according to the backup handling procedure corresponding to the manual fault handling procedure. The human-machine interaction abnormal information may involve communication problems between the operator and the nuclear power plant start-stop control system according to the embodiments of the present application, operation interface failures, etc. In this case, the nuclear power plant start-stop control system according to the embodiments of the present application can automatically take pre-set response measures to ensure the safe operation of the nuclear power plant.

[0165] In step S902 of some embodiments, load a second type of preset response program that matches the backup handling procedure to perform an abnormal feedback operation.

[0166] It should be noted that the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application can load the second type of preset response program that matches the standby processing sequence to perform abnormal feedback operations. These preset response programs are preset according to the standby processing sequence and can automatically execute a series of operations in the case of abnormal human-computer interaction. For example, if the operator cannot respond to the prompt of the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application in a timely manner, the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application can automatically switch to standby equipment or take other safety measures to ensure the safe operation of the nuclear power plant.

[0167] It should be understood that by loading the preset response program of the standby processing sequence before the fault manual processing sequence, the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application can quickly respond in the case of abnormal human-computer interaction and avoid potential risks caused by the operator's inability to intervene in a timely manner. This mechanism ensures the stability and safety of the nuclear power plant under various abnormal conditions and improves the reliability and operation efficiency of the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application.

[0168] In this way, through the above steps, the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application can effectively handle the abnormal conditions that may occur during the start-up and shutdown process of the nuclear power plant, ensuring the safety and reliability of the start-up and shutdown process.

[0169] In step S104 of some embodiments, in response to detecting that the abnormal information of the nuclear power plant has disappeared, continue to execute the sequence control operation from the current sequential control node;

[0170] It should be noted that step S104 involves continuing to execute the sequence control operation from the current sequential control node after detecting that the abnormal information of the nuclear power plant has disappeared. This step is crucial for ensuring the continuity and efficiency of the start-up and shutdown process of the nuclear power plant. During the execution of the sequence control operation, the embodiments of the present application can continuously monitor the operating state of the nuclear power plant. When the previously detected abnormal information no longer exists, the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application can identify this change in state. This real-time monitoring ensures that the start-up and shutdown control system of the nuclear power plant according to the embodiments of the present application can respond in a timely manner to the disappearance of the abnormal information and thus quickly resume the start-up and shutdown process.

[0171] It should be noted that once it is confirmed that the abnormal information has disappeared, the nuclear power plant start-stop control system according to the embodiments of the present application can continue to execute the sequence control operation from the currently recorded sequential control node. This means that the nuclear power plant start-stop control system according to the embodiments of the present application can return to the operation step when the abnormality occurred and continue to execute the subsequent operations in the predetermined order. This mechanism ensures the continuity of the start-stop process and avoids unnecessary interruptions caused by abnormalities. By continuing to execute the sequence control operation from the current sequential control node, the nuclear power plant start-stop control system according to the embodiments of the present application can not only ensure the safety of the start-stop process, but also improve the operation efficiency. This mechanism avoids long-term shutdowns caused by abnormalities and reduces the impact on the operation of the nuclear power plant. At the same time, the nuclear power plant start-stop control system according to the embodiments of the present application can check the relevant conditions again before continuing to execute the operation to ensure that all equipment and parameters are in a normal state, thus ensuring the safety of the start-stop process.

[0172] In some embodiments, when continuing to execute the sequence control operation, the nuclear power plant start-stop control system according to the embodiments of the present application can also coordinate with other relevant nuclear power plant start-stop control systems according to the embodiments of the present application. For example, the nuclear power plant start-stop control system according to the embodiments of the present application can also communicate with the safety nuclear power plant start-stop control system, the monitoring nuclear power plant start-stop control system, etc. of the embodiments of the present application to ensure that all nuclear power plant start-stop control systems according to the embodiments of the present application are ready to continue running. This coordination mechanism ensures the overall stability and reliability of the nuclear power plant.

[0173] In summary, the design of step S104 ensures that the nuclear power plant can quickly and safely resume the start-stop process after the abnormal information disappears. By continuing to execute the sequence control operation from the current sequential control node, the nuclear power plant start-stop control system according to the embodiments of the present application not only improves the efficiency of the start-stop process, but also ensures the safe operation of the nuclear power plant. This mechanism is an indispensable part of the nuclear power plant start-stop process and provides an important guarantee for the efficient and safe operation of the nuclear power plant.

[0174] In step S105 of some embodiments, in response to all the sequential control steps in the operation sequence specification being executed, it is confirmed whether the target nuclear power plant is in a startup state or a shutdown state.

[0175] It should be noted that step S105 involves confirming whether the target nuclear power plant is in a startup state or a shutdown state after all the sequential control steps in the operation sequence specification have been executed. This step is an important link in the nuclear power plant start-stop process and ensures the integrity and accuracy of the entire process.

[0176] It should be noted that the operation sequence procedure details all the operation steps to be executed during the start-up and shut-down processes of a nuclear power plant, and these steps are called sequential control steps. Each sequential control step corresponds to a specific operation, such as the start-up, stop, and parameter adjustment of equipment. The start-up and shut-down control system of the nuclear power plant in the embodiment of the present application executes these steps in a predetermined order to ensure that each operation is completed accurately. When all the sequential control steps have been executed, it means that all the necessary operations in the start-up and shut-down processes of the nuclear power plant have been completed according to the predetermined plan. After all the sequential control steps have been executed, the start-up and shut-down control system of the nuclear power plant in the embodiment of the present application needs to confirm whether the nuclear power plant has reached the expected start-up state or shut-down state. This confirmation process usually involves checking the key parameters and equipment status of the nuclear power plant. For example, the start-up and shut-down control system of the nuclear power plant in the embodiment of the present application can check the power level of the reactor, the operating status of the start-up and shut-down control system of the nuclear power plant in the embodiment, the activation status of the safety start-up and shut-down control system of the nuclear power plant in the embodiment, etc. Through these checks, the start-up and shut-down control system of the nuclear power plant in the embodiment of the present application can determine whether the nuclear power plant has been successfully started up or safely shut down.

[0177] It should be clear that the step of confirming the status of the nuclear power plant ensures the integrity of the start-up and shut-down processes. If the nuclear power plant fails to reach the expected state after all the sequential control steps have been executed, the start-up and shut-down control system of the nuclear power plant in the embodiment of the present application can issue an alarm and record relevant data for the operator to conduct further inspections and processing. This mechanism ensures that any potential problems can be discovered and solved in a timely manner, avoiding safety risks caused by unclear status. By confirming the start-up or shut-down state of the nuclear power plant, the start-up and shut-down control system of the nuclear power plant in the embodiment of the present application can provide clear feedback to the operator. The operator can judge whether the start-up and shut-down processes are successful based on this feedback and decide on subsequent operations. For example, if the nuclear power plant is successfully started up, the operator can continue with subsequent operation operations; if the nuclear power plant is successfully shut down, the operator can perform maintenance or inspection work.

[0178] It should be understood that by confirming the status of the nuclear power plant after all the sequential control steps have been executed, the integrity and accuracy of the start-up and shut-down processes are ensured. This process not only provides clear feedback but also ensures the safe operation of the nuclear power plant. Through this mechanism, the nuclear power plant can complete the start-up and shut-down processes efficiently and safely.
