[0002] As a representative of modern complex industrial systems, nuclear power plants involve a massive system scale, complex operating conditions, and numerous pieces of equipment. During the start-up and shutdown of the unit, changes in equipment status and parameters require operators to perform a large number of precise manual operations. This not only increases the operational workload and mental stress but also easily leads to omissions or errors in operation, thereby increasing the risk of the unit deviating from normal operation.

[0003] Traditional nuclear power plant operations rely on paper documents and digital control systems, which, while enabling basic operational control and status monitoring, are significantly lacking in automation and intelligence.

[0065] As a representative of modern complex industrial systems, nuclear power plants involve a massive system scale, complex operating conditions, and numerous pieces of equipment. During the start-up and shutdown of the unit, changes in equipment status and parameters require operators to perform a large number of precise manual operations. This not only increases the operational workload and mental stress but also easily leads to omissions or errors in operation, thereby increasing the risk of the unit deviating from normal operation.

[0066] Traditional nuclear power plant operations rely on paper documents and digital control systems, which, while enabling basic operational control and status monitoring, are significantly lacking in automation and intelligence. With technological advancements, the application of automation and intelligent technologies in nuclear power plants is becoming an inevitable trend to reduce operator workload, standardize operating procedures, lower the risk of misoperation, and improve unit availability.

[0067] Although related technologies have made some progress in the digitalization and portability of nuclear power plant operation procedures, these technical solutions still have many shortcomings.

[0068] For example, some technical solutions are based on overall operating strategies and are converted into executable operating procedures. However, this approach requires a large amount of basic documentation and familiarity with the configuration of nuclear power plant systems, and is not suitable for nuclear power plants based on automatic start-stop technology.

[0069] While other technical solutions have made the operating procedures portable, they are mainly aimed at local operators, maintenance and repair personnel. For complex unit start-up and shutdown processes, operators still need to complete the operation and monitoring in the main control room.

[0070] In addition, some technical solutions only provide methods for digitizing operating procedures, which cannot guide operators to use and cooperate with the automatic start-stop system to complete the automatic start-stop operation of the unit, and involve modifying the original procedures, which may lead to conflicts in user experience.

[0071] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a nuclear power plant start-up and shutdown method, its control system, electronic equipment, and storage medium, which can improve the availability of unit operation while reducing the risk of misoperation during the start-up and shutdown process of nuclear power plants.

[0072] The following explanation is based on the accompanying drawings.

[0073] Reference Figure 1 The nuclear power plant start-up and shutdown method according to the first aspect of this application may include:

[0074] Step S101: Obtain the operation sequence procedure and fault handling procedure. The operation sequence procedure includes the sequential control steps matched to multiple controlled nuclear power devices in the target nuclear power plant.

[0075] Step S102: In response to receiving the nuclear power plant start-up and shutdown command, sequential control operations are performed on each controlled nuclear power device in sequence according to the control sequence steps in the operation sequence procedure;

[0076] Step S103: In response to the detection of abnormal information of the nuclear power plant during the execution of the sequential control operation, the sequential control operation is stopped and the current sequential control node is recorded. In accordance with the fault handling procedure, an abnormal feedback operation matching the abnormal information of the nuclear power plant is executed.

[0077] Step S104: In response to the detection that the abnormal information of the nuclear power plant has disappeared, continue to execute the sequential control operation from the current sequential control node;

[0078] Step S105: In response to the execution of all sequential control steps in the operation sequence procedure, the target nuclear power plant is confirmed to be in a startup or shutdown state.

[0079] The nuclear power plant start-up and shutdown method described in this application significantly improves unit availability while reducing the risk of misoperation. Specifically, by automating the sequential control operations, the need for manual operation is reduced, thus lowering the risk of misoperation; by detecting and processing abnormal information in real time, the safe operation of the unit under abnormal conditions is ensured; and by continuing operation from the abnormal point, downtime is reduced, improving unit availability. These measures work together to provide a strong guarantee for the efficient and safe operation of nuclear power plants.

[0080] In some embodiments, step S101 involves obtaining an operating sequence procedure and a fault handling procedure, wherein the operating sequence procedure includes a sequential control sequence matched to multiple controlled nuclear power devices in the target nuclear power plant.

[0081] It should be noted that step S101 involves obtaining the operating sequence procedure and fault handling procedure, wherein the operating sequence procedure includes a sequential control sequence that matches multiple controlled nuclear power devices in the target nuclear power plant. This process forms the basis of the nuclear power plant start-up and shutdown method, ensuring the orderliness and accuracy of subsequent operations.

[0082] It should be noted that the operating sequence procedures are core documents in the start-up and shutdown process of a nuclear power plant, detailing the operating steps and sequence for each controlled nuclear power device. These operating sequence procedures are pre-compiled according to the specific design and operational requirements of the nuclear power plant, covering all stages from unit startup to shutdown. By acquiring these operating sequence procedures, the nuclear power plant start-up and shutdown control system of this application embodiment can execute operations according to a predetermined logical sequence, reducing operator intervention and lowering the risk of misoperation. Specifically, the sequential control steps in the operating sequence procedures correspond one-to-one with multiple controlled nuclear power devices in the target nuclear power plant. This means that the operating steps and logic of each device have been planned and recorded in detail. Through this matching, the nuclear power plant start-up and shutdown control system of this application embodiment can ensure that each device operates in the correct sequence and under the correct conditions during the start-up and shutdown process. This precise matching not only improves the accuracy of operation but also ensures the safe operation of the equipment.

[0083] In addition to the sequence control procedures, this embodiment also requires the acquisition of fault handling procedures. These fault handling procedures provide methods and steps for handling abnormal situations. By integrating the fault handling procedures, the nuclear power plant start-up and shutdown control system of this embodiment can react quickly when encountering an anomaly, stopping the sequential control operation and recording the current sequence control node. This provides important information for subsequent fault investigation and handling, ensuring the safe operation of the nuclear power plant under abnormal conditions.

[0084] By acquiring operating sequence procedures and fault handling procedures, the nuclear power plant start-up and shutdown control system of this application embodiment can ensure the orderly and accurate operation during the start-up and shutdown process of the nuclear power plant. The operating sequence procedures provide detailed operating steps, while the fault handling procedures ensure rapid response in abnormal situations. This comprehensive procedure system not only improves operational efficiency but also significantly reduces the risk of misoperation, providing strong protection for the safe operation of the nuclear power plant.

[0085] In some embodiments, step S102 involves, in response to receiving a nuclear power plant start-up / shutdown command, sequential control operations are performed on each controlled nuclear power device in sequence according to the control sequence steps in the operation sequence procedure.

[0086] It should be noted that step S102 involves, in response to receiving a nuclear power plant start-up / shutdown command, performing sequential control operations on each controlled nuclear power device according to the sequential control steps in the operation sequence procedure. This process is the core of the nuclear power plant start-up / shutdown method, ensuring the automation and accuracy of the start-up / shutdown process.

[0087] It should be noted that when a nuclear power plant needs to be started or stopped, the operator can issue corresponding start / stop commands. These commands can be manually entered or triggered by the nuclear power plant start / stop control system of this embodiment. Upon receiving the start / stop command, the nuclear power plant start / stop control system in this embodiment can initiate the corresponding program to prepare for the start / stop operation.

[0088] In some embodiments of this application, the operating sequence procedures can be pre-programmed, containing all necessary operational steps and logic during the start-up and shutdown of a nuclear power plant. These operating sequence procedures specify in detail the operating order and conditions for each controlled nuclear power device. The nuclear power plant start-up and shutdown control system of this application can sequentially execute sequential control operations on each controlled nuclear power device according to these procedures. Sequential control operations refer to the nuclear power plant start-up and shutdown control system of this application controlling each controlled nuclear power device in a predetermined order. The operating steps and logic for each device have been planned and recorded in detail. The nuclear power plant start-up and shutdown control system of this application can execute these operations sequentially, ensuring that each controlled nuclear power device is started or stopped at the correct time and under the correct conditions.

[0089] By automating the sequential control operations, the nuclear power plant start-up and shutdown control system of this application embodiment can ensure the accuracy and consistency of the start-up and shutdown process. Automated operation reduces manual intervention by operators and lowers the risk of misoperation. At the same time, the nuclear power plant start-up and shutdown control system of this application embodiment can monitor the status and parameters of the equipment in real time, ensuring the accuracy and timeliness of each operation step.

[0090] During the execution of sequential control operations, the nuclear power plant start-up and shutdown control system of this application embodiment can monitor the status and parameters of the equipment in real time. If any abnormality is detected, the nuclear power plant start-up and shutdown control system of this application embodiment can stop operation and issue an alarm. This ensures the safety and reliability of the start-up and shutdown process.

[0091] It should be understood that by responding to start-up and shutdown commands and executing sequential control operations according to the operating sequence procedure, the nuclear power plant start-up and shutdown control system of this application can ensure the automation and accuracy of the nuclear power plant start-up and shutdown process. This process not only improves operational efficiency but also significantly reduces the risk of misoperation, providing strong protection for the safe operation of the nuclear power plant.

[0092] Reference Figure 2 According to some embodiments of this application, the operation sequence procedure includes multiple sets of sequential control steps corresponding to different functional requirements. Step S102, according to the sequential control steps in the operation sequence procedure, sequentially performs sequential control operations on each controlled nuclear power device, which may include:

[0093] Step S201: Determine the inter-group arrangement order of each group of sequential control steps in the running sequence procedure;

[0094] Step S202: Based on the inter-group arrangement order, traverse the sequential control steps of each group to perform sequential control operations on each controlled nuclear power equipment that match the corresponding functional requirements.

[0095] In some embodiments, step S201 involves determining the inter-group arrangement order of each group of sequential control steps in the execution sequence procedure;

[0096] It should be noted that during the start-up and shutdown of a nuclear power plant, the steps requiring different functionalities must be executed in a specific logical order. For example, the activation of the safety system may need to be completed before the nuclear power plant start-up and shutdown control system of this embodiment of the application is loaded, while the adjustment of the cooling system may need to be performed after the reactor reaches a stable state. By determining the correct order of the steps, it can be ensured that each functional requirement step group is executed at the appropriate time, thereby guaranteeing the safety and stability of the entire start-up and shutdown process. This order is usually determined based on factors such as the nuclear power plant's design requirements, safety regulations, and operational experience. When determining the order of the steps, the interdependencies and potential conflicts between the step groups also need to be considered. For example, the execution of some step groups may require conditions or parameters provided by other step groups, so it is necessary to ensure that these step groups are arranged in the correct order. In addition, it is also necessary to avoid equipment damage or operational risks caused by improper arrangement of step groups.

[0097] In some embodiments, step S202 involves traversing the sequential control steps of each group based on the inter-group arrangement order to perform sequential control operations on each controlled nuclear power device that match the corresponding functional requirements.

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

[0099] While traversing each control sequence, the nuclear power plant start-up and shutdown control system of this embodiment can monitor the status and parameters of the equipment in real time and adjust the operating strategy based on feedback information. If an abnormal situation occurs during the execution of a certain sequence group, the nuclear power plant start-up and shutdown control system of this embodiment can immediately stop the execution of the current sequence group and trigger a fault handling mechanism. Once the abnormal situation is resolved, the nuclear power plant start-up and shutdown control system of this embodiment can continue executing the sequence group from the stopped position, ensuring the integrity and continuity of the start-up and shutdown process. In this way, the nuclear power plant start-up and shutdown control system of this embodiment can flexibly respond to various possible situations and ensure the safe operation of the nuclear power plant during the start-up and shutdown process.

[0100] Reference Figure 3According to some embodiments of this application, the sequential control operation includes automatically executed operations and manually executed operations. Step S202 traverses the sequential control steps of each group based on the inter-group arrangement order to execute sequential control operations matching the corresponding functional requirements on each controlled nuclear power device, which may include:

[0101] Step S301: In response to the sequential control operation, an automatic execution operation is performed, an automatic control program is obtained based on the sequential control steps, and an automatic execution operation is performed on the controlled nuclear power equipment based on the automatic control program;

[0102] In step S302, in response to the sequential control operation being a manual execution operation, a first interactive prompt operation is performed on the operator based on the sequential control step sequence 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.

[0103] In some embodiments, step S301 involves obtaining an automatic control program based on the sequential control step sequence in response to the sequential control operation being an automatic execution operation, and performing the 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 automatically executed operation, the nuclear power plant start-up and shutdown control system of this application embodiment can obtain the corresponding automatic control program based on the sequential control sequence, and perform automatic execution operations on the controlled nuclear power equipment based on the program. Specifically, the nuclear power plant start-up and shutdown control system of this application embodiment can automatically call a pre-set control program according to the current sequential control sequence to precisely control the equipment. For example, during reactor startup, the nuclear power plant start-up and shutdown control system of this application embodiment can automatically adjust the coolant flow and temperature according to the sequential control sequence 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-up and shutdown process, reduce human intervention, and reduce the risk of misoperation.

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

[0106] It should be noted that when the sequential control operation is a manual operation, the nuclear power plant start-up and shutdown control system of this application embodiment can perform a first interactive prompt operation to the operator based on the sequential control sequence, prompting the operator to issue a first interactive operation command, and then perform the manual operation according to the command. Specifically, the nuclear power plant start-up and shutdown control system of this application embodiment can issue a clear prompt to the operator based on the current sequential control sequence, informing them of the operation to be performed. After receiving the prompt, the operator can issue corresponding operation commands according to the actual situation, and the nuclear power plant start-up and shutdown control system of this application embodiment will then perform the manual operation according to these commands. For example, during the start-up or shutdown process of certain critical equipment, the nuclear power plant start-up and shutdown control system of this application embodiment can prompt the operator to perform manual confirmation to ensure the safety and accuracy of the operation. This manual operation provides the operator with the necessary control, enabling them to intervene when necessary, ensuring the safety and reliability of the start-up and shutdown process.

[0107] It should be understood that by combining automatic and manual execution of operations, the nuclear power plant start-up and shutdown control system of this application embodiment can flexibly respond to different functional requirements and operational scenarios. In scenarios requiring high precision and efficiency, automatic execution ensures the smooth progress of the start-up and shutdown process; while in scenarios requiring operator judgment and intervention, manual execution provides the necessary flexibility and safety. This integrated execution method not only improves the efficiency of the start-up and shutdown process but also ensures the safety and reliability of the entire process.

[0108] Reference Figure 4 According to some embodiments of this application, step S302, based on the sequential control step sequence, performs a first interactive prompt operation to the operator to prompt the operator to issue a first interactive operation instruction, and performs a manual execution operation according to the first interactive operation instruction, which may include:

[0109] Step S401: When the manual operation is an authorized operation type, an authorization prompt operation is performed to the administrator based on the sequential control step order to prompt the administrator to issue an authorization instruction;

[0110] In step S402, in response to receiving the authorization instruction, a first interactive prompt operation is performed on the operator according to the control sequence and the authorization instruction, so as to prompt the operator to issue a first interactive operation instruction, and to perform a manual operation according to the first interactive operation instruction.

[0111] In some embodiments, step S401 involves performing an authorization prompt operation on the administrator based on the sequential control step order when the manually executed operation is an authorization operation type, so as to prompt the administrator to issue an authorization instruction;

[0112] It should be noted that when a manually executed operation falls under the category of authorized operations, the nuclear power plant start-up and shutdown control system of this application embodiment can issue an authorization prompt to the administrator based on the sequential control steps. This step is to ensure that critical operations receive appropriate approval and supervision. The nuclear power plant start-up and shutdown control system of this application embodiment can issue a clear prompt to the administrator based on the current sequential control steps, informing them of the required operation. After receiving the prompt, the administrator can issue an authorization instruction based on the actual situation. This mechanism ensures that only authorized operations can be executed, thereby improving the safety and reliability of operations.

[0113] In some embodiments, step S402 involves responding to receiving an authorization instruction by performing a first interactive prompt operation on the operator according to the sequence of steps and the authorization instruction, prompting the operator to issue a first interactive operation instruction, and performing a manual operation according to the first interactive operation instruction.

[0114] It should be noted that once the nuclear power plant start-up and shutdown control system of this embodiment receives the authorization instruction from the administrator, it can perform a first interactive prompt operation to the operator according to the control sequence and the instruction. This step ensures that the operator has received the necessary authorization and guidance before performing manual operation. The nuclear power plant start-up and shutdown control system of this embodiment can issue clear prompts to the operator, informing them of the required operation. After receiving the prompts, the operator can issue the first interactive operation instruction according to the actual situation. The nuclear power plant start-up and shutdown control system of this embodiment performs manual operation according to these instructions, ensuring the accuracy and safety of the operation.

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

[0116] It should be understood that this authorization-based operating mechanism enables the nuclear power plant start-up and shutdown control system of this application embodiment to flexibly respond to different operational needs. In scenarios requiring high safety and compliance, administrator authorization ensures the rigor of operations. In scenarios requiring operator judgment and intervention, the interactive prompts provided by the nuclear power plant start-up and shutdown control system of this application embodiment ensure the accuracy and timeliness of operations. This flexible operating mechanism not only improves the efficiency of the start-up and shutdown process but also ensures the safety and reliability of the entire process.

[0117] Reference Figure 5According to some embodiments of this application, step S202, which traverses the sequential control steps of each group based on the inter-group arrangement order to perform sequential control operations on each controlled nuclear power device that match the corresponding functional requirements, may include:

[0118] Step S501: For each sequential control step in the running sequence procedure, if the sequential control operation corresponding to the sequential control step has been executed, configure the corresponding step completion flag for the sequential control step.

[0119] Step S502: In response to receiving the step sequence progress query instruction, step sequence progress representation information is generated according to each sequential control step configured with a step sequence completion identifier in the running sequence procedure.

[0120] In step S501 of some embodiments, for each sequential control step in the running sequence procedure, if the sequential control operation corresponding to the sequential control step has been executed, a corresponding step completion identifier is configured for the sequential control step.

[0121] It should be noted that during the execution of sequential control operations, the nuclear power plant start-up and shutdown control system of this application embodiment can monitor each sequential control step in the operating sequence procedure. When the sequential control operation corresponding to a certain sequential control step has been executed, the nuclear power plant start-up and shutdown control system of this application embodiment can configure a corresponding step completion flag for that sequential control step. The purpose of this flag is to clearly indicate that the step has been completed, providing a reference for subsequent operations. For example, during reactor startup, after the coolant nuclear power plant start-up and shutdown control system of this application embodiment has completed the startup operation according to the predetermined steps, the nuclear power plant start-up and shutdown control system of this application embodiment can configure a completion flag for that step to indicate that this part of the operation has been successfully executed. This flag mechanism not only helps operators understand the progress of the startup and shutdown process in real time, but also provides an important basis for the automated management of the nuclear power plant start-up and shutdown control system of this application embodiment.

[0122] In some embodiments, step S502, in response to receiving a step progress query instruction, generates step progress representation information according to each sequential control step configured with a step completion identifier in the running sequence procedure.

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

[0124] Reference Figure 6 According to some embodiments of this application, step S102, which involves sequentially performing sequential control operations on each controlled nuclear power device according to the control sequence in the operation sequence procedure, may include:

[0125] Step S601: For controlled nuclear power equipment with switch control, perform equipment start-up or equipment shutdown operations on the controlled nuclear power equipment based on the sequential control steps;

[0126] Step S602: For controlled nuclear power equipment with analog quantity control, the controlled nuclear power equipment is set to automatic mode based on the sequential control step, so that the controlled nuclear power equipment can perform analog quantity adaptive control for the corresponding analog quantity.

[0127] Step S603: For controlled nuclear power equipment that collects information, control the controlled nuclear power equipment to perform data acquisition operations based on the sequential control steps.

[0128] In some embodiments, step S601 involves performing a device start-up or device shutdown operation on the controlled nuclear power equipment based on a sequential control step sequence for the controlled nuclear power equipment of the switch quantity control type.

[0129] It should be noted that for controlled nuclear power equipment with on / off control, the nuclear power plant start-up and shutdown control system of this application embodiment can perform equipment start-up or equipment shutdown operations on these devices based on a sequential control sequence. On / off control devices typically refer to those devices with only two states, on and off, such as circuit breakers and disconnect switches. The correct operation of these devices is crucial during the start-up and shutdown process of a nuclear power plant. For example, during reactor startup, the nuclear power plant start-up and shutdown control system of this application embodiment can sequentially open the relevant circuit breakers according to the sequential control sequence to ensure normal power supply; during reactor shutdown, these circuit breakers can be sequentially closed to ensure equipment safety. By automating these operations, the nuclear power plant start-up and shutdown control system of this application embodiment can ensure that each device is turned on or off at the correct time, thereby improving the efficiency and safety of the start-up and shutdown process.

[0130] In step S602 of some embodiments, for controlled nuclear power equipment of analog quantity control type, the controlled nuclear power equipment is set to automatic mode based on the sequential control step sequence, 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 using analog quantity control, the nuclear power plant start-up and shutdown control system of this application embodiment can set these devices to automatic mode based on a sequential control step, enabling the devices to adaptively control the corresponding analog quantities. Analog quantity control equipment typically refers to equipment that requires adjustment of continuous variables, such as pumps and valves. In automatic mode, these devices can automatically adjust their output based on real-time operating parameters to meet the operational needs of the nuclear power plant. For example, in the reactor cooling system, the nuclear power plant start-up and shutdown control system of this application embodiment can set the cooling pump to automatic mode based on a sequential control step, enabling it to automatically adjust the pump speed according to the temperature and flow rate of the cooling water, ensuring the reactor operates within a safe temperature range. This adaptive control can improve equipment operating efficiency, reduce human intervention, and lower the risk of misoperation.

[0132] In some embodiments, step S603 involves controlling the controlled nuclear power equipment to perform data acquisition operations based on a sequential control step sequence for information acquisition-type controlled nuclear power equipment.

[0133] It should be noted that for controlled nuclear power equipment involving information acquisition, the nuclear power plant start-up and shutdown control system of this application embodiment can control these devices to perform data acquisition operations based on a sequential control step. Information acquisition equipment typically refers to devices used to monitor the operating status of a nuclear power plant, such as sensors and monitoring instruments. During the start-up and shutdown process of a nuclear power plant, these devices can collect various operating parameters in real time, such as temperature, pressure, and flow rate, and transmit the data to the nuclear power plant start-up and shutdown control system of this application embodiment. The nuclear power plant start-up and shutdown control system of this application embodiment can perform real-time monitoring and analysis based on this data to ensure that the operating status of the nuclear power plant is always within a safe range. For example, during reactor startup, the nuclear power plant start-up and shutdown control system of this application embodiment can control temperature sensors to collect reactor core temperature data according to a sequential control step, and transmit this data to the nuclear power plant start-up and shutdown control system of this application embodiment, so that operators can understand the reactor temperature changes in real time. This real-time data acquisition can improve the operational transparency of the nuclear power plant and provide operators with timely decision-making basis.

[0134] In some embodiments, step S103, in response to the detection of nuclear power plant abnormal information during the execution of sequential control operation, stops the sequential control operation and records the current sequential control node, and performs an abnormal feedback operation matching the nuclear power plant abnormal information according to the fault handling procedure.

[0135] It should be noted that step S103 involves stopping the sequential control operation and recording the current sequential control node when an abnormal information of the nuclear power plant is detected during the execution of the sequential control operation, and then executing the matching abnormal feedback operation according to the fault handling procedure. This process is crucial to ensuring that the nuclear power plant can safely and effectively handle problems when encountering abnormal situations during start-up and shutdown.

[0136] It should be noted that during the execution of sequential control operations, the nuclear power plant start-up and shutdown control system of this application embodiment can monitor various operating parameters and equipment status of the nuclear power plant in real time. If the nuclear power plant start-up and shutdown control system of this application embodiment detects any abnormal information through sensing components such as sensors, such as equipment failure, parameters exceeding the normal range, or system errors, it can trigger an abnormality handling mechanism. This real-time monitoring ensures that the nuclear power plant start-up and shutdown control system of this application embodiment can respond quickly to any potential problems, thereby preventing the abnormal situation from deteriorating further. Once abnormal information is detected, the nuclear power plant start-up and shutdown control system of this application embodiment can stop the current sequential control operation. This measure is to prevent the abnormal situation from further escalating when the operation continues, ensuring the safe operation of the nuclear power plant. Stopping the sequential control operation is an emergency measure designed to protect the safety of equipment and personnel, while providing a stable state for subsequent fault handling.

[0137] On the other hand, while halting sequential control operations, the nuclear power plant start-up and shutdown control system of this application embodiment can record the current sequential control node. This recording is crucial because it provides key information for subsequent fault handling and operation recovery. By recording the current node, the nuclear power plant start-up and shutdown control system of this application embodiment can know which step the operation was at when the anomaly occurred, thus enabling it to continue operation from the correct position after fault handling is completed.

[0138] It should be clarified that, according to the fault handling procedures, the nuclear power plant start-up and shutdown control system of this application embodiment can execute anomaly feedback operations that match the detected abnormal information. These operations may include isolating faulty equipment, switching to a standby system, adjusting operating parameters, or notifying maintenance personnel. The purpose of the anomaly feedback operations is to resolve the abnormal problem as quickly as possible and restore the system to normal operation. These operations are predefined to ensure that action can be taken quickly and effectively in abnormal situations.

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

[0140] Reference Figure 7 According to some embodiments of this application, step S103, in response to the detection of nuclear power plant anomaly information during the execution of the sequential control operation, stops the sequential control operation and records the current sequential control node, and executes an anomaly feedback operation matching the nuclear power plant anomaly information according to the fault handling procedure, which may include:

[0141] Step S701: In response to the detection of abnormal information of the nuclear power plant during the execution of the sequential control operation, stop the sequential control operation and record the current sequential control node;

[0142] Step S702: If the abnormal information of the nuclear power plant includes abnormal equipment parameters, perform an abnormality feedback operation according to the fault handling procedure matched with the abnormal equipment parameters.

[0143] Step S703: If the abnormal information of the nuclear power plant includes abnormal information of unit operation, perform an abnormal feedback operation according to the fault handling procedure matched with the abnormal information of unit operation.

[0144] In some embodiments, step S701 involves stopping the sequential control operation and recording the current sequential control node in response to detecting abnormal information about the nuclear power plant during the execution of the sequential control operation.

[0145] It should be noted that when an abnormality is detected during the execution of the sequential control operation, the nuclear power plant start-up and shutdown control system of this embodiment can immediately stop the current sequential control operation and record the current sequential control node. This mechanism ensures that the nuclear power plant start-up and shutdown control system of this embodiment can react quickly in abnormal situations, preventing the abnormal situation from worsening. Recording the current sequential control node provides important information for subsequent fault handling, enabling the nuclear power plant start-up and shutdown control system of this embodiment to continue operation from the correct position after fault handling is completed. For example, if an abnormality is detected in the cooling system during reactor startup, the nuclear power plant start-up and shutdown control system of this embodiment can immediately stop the startup operation and record the current startup steps for subsequent targeted fault handling.

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

[0147] It should be noted that if the detected abnormal information from the nuclear power plant includes abnormal equipment parameters, the nuclear power plant start-up and shutdown control system of this application embodiment can execute abnormal feedback operations according to the fault handling procedure matched to the abnormal information. Abnormal equipment parameters may involve key parameters such as temperature, pressure, and flow rate exceeding normal ranges. The nuclear power plant start-up and shutdown control system of this application embodiment can take corresponding measures according to the pre-set fault handling procedure, such as adjusting the equipment operating status, switching to standby equipment, or performing an emergency shutdown. For example, if an abnormal increase in reactor coolant temperature is detected, the nuclear power plant start-up and shutdown control system of this application embodiment can automatically adjust the coolant flow rate or switch to the standby cooling system according to the fault handling procedure to ensure the safe operation of the reactor.

[0148] In some embodiments, step S703 involves performing an anomaly feedback operation according to a fault handling procedure that matches the unit operation anomaly information, in the case that the nuclear power plant anomaly information includes unit operation anomaly information.

[0149] It should be noted that if the detected abnormal information from the nuclear power plant includes abnormal unit operation information, the nuclear power plant start-up and shutdown control system of this application embodiment can execute abnormal feedback operations according to the fault handling procedure matched to the abnormal information. Abnormal unit operation may involve errors in operating procedures, equipment operation failures, etc. The nuclear power plant start-up and shutdown control system of this application embodiment can provide corresponding operating guidance or automatically take corrective measures according to the fault handling procedure. For example, if a critical piece of equipment fails to start successfully during unit startup, the nuclear power plant start-up and shutdown control system of this application embodiment can prompt the operator to manually intervene or automatically attempt to restart the equipment according to the fault handling procedure to ensure a smooth startup process.

[0150] Reference Figure 8 According to some embodiments of this application, the fault handling procedure includes at least one fault handling step. Step S103, in response to the detection of nuclear power plant anomaly information during the execution of sequential control operations, stops the sequential control operations and records the current sequential control node, and executes an anomaly feedback operation matching the nuclear power plant anomaly information according to the fault handling procedure, which may include:

[0151] Step S801: In response to the detection of abnormal information of the nuclear power plant during the execution of the sequential control operation, stop the sequential control operation and record the current sequential control node;

[0152] Step S802: In response to the fault handling sequence being an automatic fault handling sequence, load a first type of preset response program that matches the automatic fault handling sequence to perform an exception feedback operation.

[0153] In step S803, in response to the fault handling sequence being a manual fault handling sequence, a preset interactive program matching the manual fault handling sequence is loaded, and a second interactive prompt operation is performed to prompt the operator to issue a second interactive operation command to perform an exception feedback operation.

[0154] In some embodiments, step S801 involves stopping the sequential control operation and recording the current sequential control node in response to detecting abnormal information about the nuclear power plant during the execution of the sequential control operation.

[0155] It should be noted that when an anomaly is detected during the execution of the sequential control operation, this embodiment can immediately stop the current sequential control operation and record the current sequential control node. This mechanism ensures that this embodiment can react quickly in abnormal situations, preventing further deterioration. Recording the current sequential control node provides crucial information for subsequent fault handling, enabling this embodiment to continue operation from the correct position after fault handling is completed. For example, if an anomaly is detected in the cooling system during reactor startup, this embodiment can immediately stop the startup operation and record the current startup steps for subsequent targeted fault handling.

[0156] In some embodiments, step S802, in response to the fault handling sequence being an automatic fault handling sequence, loads a first type of preset response program matching the automatic fault handling sequence to perform an exception feedback operation.

[0157] It should be noted that if the fault handling sequence is an automatic fault handling sequence, this embodiment can load a first-type preset response program matching that sequence to perform anomaly feedback operations. These preset response programs are pre-set based on common fault types and handling methods, and can automatically execute a series of operations to deal with abnormal situations. For example, if abnormal equipment parameters are detected, this embodiment can automatically adjust the equipment operating status or switch to standby equipment to ensure the safe operation of the nuclear power plant. This automatic handling mechanism can quickly respond to abnormal situations, reduce human intervention, and improve the efficiency and accuracy of fault handling.

[0158] In some embodiments, step S803, in response to the fault handling sequence being a manual fault handling sequence, loads a preset interactive program matching the manual fault handling sequence and performs a second interactive prompt operation to prompt the operator to issue a second interactive operation command to perform an exception feedback operation.

[0159] It should be noted that if the fault handling sequence is a manual fault handling sequence, the nuclear power plant start-up and shutdown control system of this application embodiment can load a preset interactive program matching the sequence and perform a second interactive prompt operation to prompt the operator to issue a second interactive operation command, thereby performing an anomaly feedback operation. In this case, the nuclear power plant start-up and shutdown control system of this application embodiment can provide detailed fault information and handling suggestions, and the operator can perform manual operation based on this information and suggestions. For example, if an abnormality in unit operation is detected, the nuclear power plant start-up and shutdown control system of this application embodiment can prompt the operator to perform manual intervention, such as adjusting the operating procedure or checking the equipment status. This manual handling mechanism ensures that in complex or special situations, the operator can flexibly handle the situation according to the actual situation, ensuring the safe operation of the nuclear power plant.

[0160] Reference Figure 9 According to some embodiments of this application, the fault handling procedure further includes alternative handling steps corresponding to each fault manual handling step sequence. Before loading the preset interactive program matching the fault manual handling step sequence in step S803 and performing the second interactive prompt operation to the operator, it may also include:

[0161] Step S901: In response to abnormal information from the nuclear power plant, including abnormal information from human-machine interaction, determine the backup handling sequence corresponding to the manual fault handling sequence, and identify a second type of preset response procedure that matches the backup handling sequence.

[0162] Step S902: Load the second type of preset response program that matches the standby processing sequence to perform the exception feedback operation.

[0163] In some embodiments, step S901 involves responding to abnormal information from the nuclear power plant, including abnormal information from human-machine interaction, by determining a backup processing sequence corresponding to the manual fault handling sequence, and identifying a second type of preset response procedure that matches the backup processing sequence.

[0164] It should be noted that if the abnormal information from the nuclear power plant includes human-machine interface (HMI) abnormal information, the nuclear power plant start-up and shutdown control system of this application embodiment can determine a second type of preset response procedure matching the backup processing sequence corresponding to the manual fault handling sequence. HMI abnormal information may involve communication problems between the operator and the nuclear power plant start-up and shutdown control system of this application embodiment, or user interface malfunctions. In such cases, the nuclear power plant start-up and shutdown control system of this application embodiment can automatically take pre-set response measures to ensure the safe operation of the nuclear power plant.

[0165] In some embodiments, step S902 involves loading a second type of preset response program that matches the alternate processing sequence to perform an exception feedback operation.

[0166] It should be noted that the nuclear power plant start-up and shutdown control system of this application embodiment can load a second type of preset response program that matches the standby processing sequence to perform anomaly feedback operations. These preset response programs are pre-set according to the standby processing sequence and can automatically execute a series of operations in the event of human-machine interaction anomalies. For example, if the operator cannot respond to the prompts of the nuclear power plant start-up and shutdown control system of this application embodiment in a timely manner, the nuclear power plant start-up and shutdown control system of this application embodiment 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 a preset response program for an alternative handling procedure before the manual fault handling procedure, the nuclear power plant start-up and shutdown control system of this application embodiment can react quickly in the event of abnormal human-machine interaction, avoiding 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 operating efficiency of the nuclear power plant start-up and shutdown control system of this application embodiment.

[0168] In this way, through the above steps, the nuclear power plant start-up and shutdown control system of this application embodiment can effectively handle abnormal situations 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 some embodiments, step S104 involves continuing the sequential control operation from the current sequential control node in response to the detection that the abnormal information of the nuclear power plant has disappeared.

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

[0171] It should be noted that once the abnormal information is confirmed to have disappeared, the nuclear power plant start-up and shutdown control system of this embodiment can continue to execute sequential control operations from the recorded current sequential control node. This means that the nuclear power plant start-up and shutdown control system of this embodiment can return to the operating steps when the abnormality occurred and continue to execute subsequent operations in the predetermined order. This mechanism ensures the continuity of the start-up and shutdown process and avoids unnecessary interruptions caused by abnormalities. By continuing to execute sequential control operations from the current sequential control node, the nuclear power plant start-up and shutdown control system of this embodiment can not only ensure the safety of the start-up and shutdown process but also improve the efficiency of operation. 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-up and shutdown control system of this embodiment can recheck relevant conditions before continuing to execute operations to ensure that all equipment and parameters are in normal condition, thereby ensuring the safety of the start-up and shutdown process.

[0172] In some embodiments, while continuing to execute sequential control operations, the nuclear power plant start-up and shutdown control system of this application embodiment can also coordinate with other related nuclear power plant start-up and shutdown control systems of this application embodiment. For example, the nuclear power plant start-up and shutdown control system of this application embodiment can also communicate with the nuclear power plant start-up and shutdown control system of the safety embodiment of this application, the nuclear power plant start-up and shutdown control system of the monitoring embodiment of this application, etc., to ensure that all nuclear power plant start-up and shutdown control systems of this application embodiment are ready to continue operation. 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-up and shutdown process after the abnormal information disappears. By continuing to execute sequential control operations from the current sequential control node, the nuclear power plant start-up and shutdown control system of this application embodiment not only improves the efficiency of the start-up and shutdown process but also ensures the safe operation of the nuclear power plant. This mechanism is an indispensable part of the nuclear power plant start-up and shutdown process, providing an important guarantee for the efficient and safe operation of the nuclear power plant.

[0174] In some embodiments, step S105, in response to the execution of all sequential control steps in the operation sequence procedure, confirms that the target nuclear power plant is in a startup or shutdown state.

[0175] It should be noted that step S105 involves confirming whether the target nuclear power plant is in a startup or shutdown state after all sequential control steps in the operation sequence procedure have been executed. This step is a crucial part of the nuclear power plant startup and shutdown process, ensuring the integrity and accuracy of the entire process.

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

[0177] It is important to clarify that the step of confirming the nuclear power plant's status ensures the integrity of the start-up and shutdown process. If the nuclear power plant fails to reach the expected state after all sequential control steps have been executed, the nuclear power plant start-up and shutdown control system of this application embodiment can issue an alarm and record relevant data for the operator to conduct further inspection and handling. This mechanism ensures that any potential problems can be detected and resolved in a timely manner, avoiding safety risks caused by unclear status. By confirming the start-up or shutdown status of the nuclear power plant, the nuclear power plant start-up and shutdown control system of this application embodiment can provide clear feedback to the operator. The operator can determine whether the start-up and shutdown process was successful based on this feedback and decide on subsequent operations. For example, if the nuclear power plant starts successfully, the operator can continue with subsequent operating operations; if the nuclear power plant stops successfully, the operator can perform maintenance or inspection work.

[0178] It should be understood that confirming the nuclear power plant's status after all sequential control steps are executed ensures the integrity and accuracy of the start-up and shutdown process. 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 shutdown process efficiently and safely.

[0180] The procedure acquisition module 1001 is used to acquire the operation sequence procedure and the fault handling procedure. The operation sequence procedure includes the sequential control steps that match multiple controlled nuclear power equipment in the target nuclear power plant.

[0181] The sequential control operation module 1002 is used to respond to the nuclear power plant start-up and shutdown command, and to perform sequential control operations on each controlled nuclear power equipment in sequence according to the sequential control steps in the operation sequence procedure; and to continue to perform sequential control operations from the current sequential control node in response to the detection that the abnormal information of the nuclear power plant has disappeared.

[0182] The anomaly feedback module 1003 is used to respond to the detection of nuclear power plant anomaly information during the execution of sequential control operation, stop the sequential control operation and record the current sequential control node, and execute anomaly feedback operation matching the nuclear power plant anomaly information according to the fault handling procedure.

[0183] The start / stop confirmation module 1004 is used to confirm whether the target nuclear power plant is in a start-up or stop state in response to the execution of all sequential control steps in the operation sequence procedure.
