[0077] Figure 1 It is an optional flowchart of the nuclear power plant start-up and shutdown operation guidance method provided by the embodiments of the present application. The nuclear power plant start-up and shutdown operation guidance method provided by the embodiments of the present application can be applied to the control center device of a target nuclear power unit. Figure 1 The method in may include but is not limited to steps S101 to S105.

[0078] Step S101, obtaining the start-up and shutdown sequence control information of the target nuclear power unit; wherein, the start-up and shutdown sequence control information includes a unit sequence control sequence, and the unit sequence control sequence is used to record the operation step information of the target nuclear power unit regarding start-up and shutdown control;

[0079] Step S102, in response to the target nuclear power unit obtaining a start-up and shutdown control signal, and determining a target step sequence to be currently executed according to the start-up and shutdown control signal and the start-up and shutdown sequence control information;

[0080] Step S103: Perform step parsing according to the target step sequence to generate step sequence operation indication information;

[0081] Step S104: Perform real-time monitoring on the target unit equipment corresponding to the target step sequence to obtain the equipment monitoring parameters of the target unit equipment;

[0082] Step S105: Transmit the step sequence operation indication information and the equipment monitoring parameters to the target operator to guide the target operator to perform start-stop operations on the target unit equipment.

[0083] Steps S101 to S105 illustrated in the embodiments of the present application obtain the start-stop sequence control information of the target nuclear power unit; wherein, the start-stop sequence control information includes a unit sequence control sequence, and the unit sequence control sequence is used to record the operation step information of the target nuclear power unit regarding start-stop control. In response to the target nuclear power unit obtaining a start-stop control signal, and determining the currently executed target step sequence according to the start-stop control signal and the start-stop sequence control information, perform step parsing according to the target step sequence to generate step sequence operation indication information, perform real-time monitoring on the target unit equipment corresponding to the target step sequence to obtain the equipment monitoring parameters of the target unit equipment, and transmit the step sequence operation indication information and the equipment monitoring parameters to the target operator to guide the target operator to perform start-stop operations on the target unit equipment. It can be seen from this that the present application records the operation step information of the target nuclear power unit regarding start-stop control through the unit sequence control sequence, and generates clear step sequence operation indication information by parsing the currently executed target step sequence, and conveys it to the designated target operator together with the equipment monitoring parameters of the target unit equipment, so as to provide accurate guidance information for the unit personnel to perform start-stop operations on the target nuclear power unit.

[0084] In step S101 of some embodiments, the start-stop sequence control information of the target nuclear power unit is obtained. The start-stop sequence control information records a series of steps required to be executed during the start-stop process of the target nuclear power unit, covering all stages from start-up preparation to full operation of the target nuclear power unit, and from the operating state to safe shutdown. Among them, the unit sequence control sequence is composed of specific operation step information. The operation step information of the unit sequence control sequence includes specific operation content, execution conditions, expected results, and the target unit equipment and equipment parameters involved. By obtaining the start-stop sequence control information, accurate guidance information can be provided for the unit personnel, thereby avoiding misoperation by the unit personnel and improving the safety during the control process of the nuclear power unit.

[0085] In step S102 of some embodiments, the start-stop control device responds to the start-stop control signal received by the target nuclear power unit. The start-stop control signal is a trigger signal sent to the start-stop control device, indicating that the start-stop operation has been initiated. The start-stop sequence control information includes multiple unit sequence control sequences corresponding to different functional types, and the target step sequence is the unit sequence control sequence selected from the start-stop sequence control information according to the current start-stop control signal and the current state of the target nuclear power unit. The target step sequence will become the key information guiding the start-stop operation to ensure that accurate guiding information can be provided to the unit personnel, enabling the target nuclear power unit to perform the start-stop operation safely and effectively according to the predetermined sequence and conditions.

[0086] In step S103 of some embodiments, through in-depth analysis of the target step sequence, clear and accurate step operation instruction information is generated. By detailedly analyzing the specific requirements of each step, including key information such as operating conditions, operating objects, operating sequences, and expected results, the complex target step sequence is transformed into specific and executable operation instructions, that is, step operation instruction information, so that the unit personnel can perform precise operations according to the operation instructions. The generated step operation instruction information not only includes the specific content of the operation but also can include relevant safety tips and precautions to help the unit personnel avoid potential risks during the execution process. Thereby, it greatly improves the accuracy and safety of the operation, reduces the possibility of human errors, and provides a strong guarantee for the safe start-stop of the target nuclear power unit.

[0087] Please refer to Figure 2 , in some embodiments, the target operator includes multiple unit operators, and step S103 may include but is not limited to steps S201 to S203:

[0088] Step S201, obtain the identity authentication information of the target operator;

[0089] Step S202, based on the identity authentication information, perform execution role recognition on the target operator to obtain role recognition information;

[0090] Step S203, based on the role recognition information and the target step sequence, perform step analysis to generate step operation instruction information matching the target operator.

[0091] In step S201 of some embodiments, the identity authentication information of the target operator is obtained. The identity authentication information usually includes the operator's name, work number, authority level, etc., so as to confirm the identity of the target operator and ensure that he / she has the qualification to perform relevant operations.

[0092] In step S202 of some embodiments, based on the obtained identity authentication information, the execution role of the target operator is identified to obtain role identification information. The role identification information is used to represent the analysis situation of the target operator. Through the role identification information, it not only helps to confirm the identity of the target operator, but also can determine the specific responsibilities and authorities of the target operator during the start-stop operation according to the different roles of the target operator (such as the main control operator, the auxiliary operator, the maintenance personnel, etc.).

[0093] In step S203 of some embodiments, the role identification information is combined with the target step sequence for step parsing to generate step sequence operation instruction information matching the target operator, so as to ensure that each unit operator can obtain specific guidance consistent with their responsibilities and identities when performing start-stop operations. Thus, the efficiency and accuracy of unit operations can be improved, and the safety of unit operations can be enhanced, because each unit operator can clearly understand their roles and tasks in the entire operation process.

[0094] Please refer to Figure 3 , in some embodiments, step S103 may include but is not limited to steps S301 to S302:

[0095] Step S301, in response to obtaining a manual operation instruction of the target operator, convert the operation step information involving automated operations in the target step sequence into manual operation information;

[0096] Step S302, generate step sequence operation instruction information based on the manual operation information.

[0097] In step S301 of some embodiments, after the control center device of the target nuclear power unit receives the manual operation instruction of the target operator, convert the operation step information originally set for automated operation into manual operation information suitable for manual execution.

[0098] In step S302 of some embodiments, based on the converted manual operation information, generate specific step sequence operation instruction information. When there is a problem with the system or equipment related to the automated operation of a certain part of the target nuclear power unit, or when the target operator is very familiar with a part of the operation steps and wants to execute them manually, then the target operator needs to manually complete the steps that were originally automated operations. The step sequence operation instruction information provides clear and detailed operation guidance for the target operator, covering key information such as the specific content of the operation steps, the execution order, and precautions, so that the target operator can accurately complete the manual operation task.

[0099] In step S104 of some embodiments, real-time monitoring is performed on the target unit equipment corresponding to the target step sequence, so as to obtain the actual operating state data of the target unit equipment during the start-stop operation, that is, equipment monitoring parameters. The equipment monitoring parameters include, but are not limited to, key indicators such as the temperature, pressure, flow rate, and vibration of the target unit equipment, which can directly reflect the performance and health status of the target unit equipment during the operation. By performing real-time monitoring on the target unit equipment, it can be ensured that the target operator and the automated control system can timely understand the operating state of the target unit equipment. And any abnormal situation or potential fault can be quickly identified, so as to take appropriate measures to avoid equipment damage or operation errors.

[0100] In step S105 of some embodiments, the step sequence operation instruction information and the equipment monitoring parameters obtained through detailed parsing and real-time monitoring are conveyed to the target operator. Thus, comprehensive and accurate operation guidance is provided for the target operator to ensure that the target operator can safely and efficiently complete the start-stop operation of the target nuclear power unit according to the step sequence operation instruction information and the equipment monitoring parameters. By combining the step sequence operation instruction information and the equipment monitoring parameters and conveying them to the target operator, the target operator can refer to the operation content and the equipment state simultaneously when performing each step, so as to accurately and efficiently complete the start-stop operation of the target nuclear power unit and better cope with possible abnormal situations.

[0101] Please refer to Figure 4 , in some embodiments, step S105 may include, but is not limited to, steps S401 to S402:

[0102] Step S401, perform permission analysis based on the identity authentication information of the target operator to obtain the operation permission information of the target operator;

[0103] Step S402, convey the step sequence operation instruction information and the equipment monitoring parameters to the target operator, and guide the target operator to operate the target unit equipment based on the operation permission information.

[0104] In step S401 of some embodiments, permission analysis is performed based on the identity authentication information of the target operator to obtain the operation permission information of the target operator. The operation permission information is used to record the permission information of the target operator and can reflect the safety permission level of the target operator.

[0105] In step S402 of some embodiments, the step sequence operation instruction information and equipment monitoring parameters are conveyed to the target operator, and the target operator is guided to operate the target unit equipment by matching the operation authority information of the target operator, so as to determine the safety authority level possessed by the target operator in the start-up and shutdown operations of the nuclear power unit, ensuring that the target operator can only perform start-up and shutdown operations that conform to their responsibilities and authorities, effectively preventing unauthorized operations from occurring, and thus enhancing the safety and compliance of the start-up and shutdown operations of the target nuclear power unit.

[0106] Through steps S401 to S402, combined with identity authentication and authority analysis, it can be ensured that each target operator can obtain operation guidance matching their authority when performing tasks, enabling the target operator to clearly understand the scope of operations they are authorized to perform and the safety matters that need attention when performing each step. This not only improves the flexibility and adaptability of the start-up and shutdown operations but also provides additional guarantees for the safe operation of the target nuclear power unit. For example, if a certain operation step requires specific high-level authority, then according to the authority information of the target operator, it can be decided whether to provide the operation instruction for this operation step.

[0107] Please refer to Figure 5 , in some embodiments, step S105 may include but is not limited to steps S501 to S502:

[0108] Step S501, based on the operation step information in the target step sequence, generates a step sequence operation number corresponding to the step sequence operation instruction information;

[0109] Step S502, based on the step sequence operation number, conveys the step sequence operation instruction information to multiple unit operators to guide the multiple unit operators to operate the target unit equipment in sequence.

[0110] In step S501 of some embodiments, based on the operation step information in the target step sequence, a unique step sequence operation number is generated for each operation step. The step sequence operation number is not only an identifier of the operation step but also reflects the order and logical relationship of the operation steps, enabling the target operator to clearly understand the position of each operation step in the overall operation process.

[0111] In step S502 of some embodiments, based on the step sequence operation number, the step sequence operation instruction information is conveyed to multiple unit operators, so that each unit operator can receive the step sequence operation instruction information related to their responsibilities and arranged in sequence. By the method of conveying the step sequence operation instruction information in the order of the step sequence operation number, it can be ensured that multiple operators can work together collaboratively, avoiding operation chaos and potential conflicts.

[0112] Through steps S501 to S502, not only the efficiency of start-stop operations is improved, but also the safety and reliability of start-stop operations are enhanced. Each unit operator performs tasks according to the step operation number, reducing errors caused by improper operation sequences. At the same time, this orderly operation process is also convenient for management and supervision, facilitating subsequent analysis of operation records and tracing each step in the operation process, so that problems can be quickly located and solved when they occur.

[0113] Please refer to Figure 6 , in some embodiments, step S105 may include but is not limited to steps S601 to S602:

[0114] Step S601, in response to the step operation instruction information matching the target operator satisfying the preset operation authorization condition, perform operation permission application processing based on the identity authentication information of the target operator;

[0115] Step S602, in response to the target operator obtaining the operation authorization instruction, convey the step operation instruction information and the equipment monitoring parameters to the target operator to guide the target operator to perform start-stop operations on the target unit equipment.

[0116] In step S601 of some embodiments, in response to the step operation instruction information of the target operator satisfying the preset operation authorization condition, perform permission application processing based on the identity authentication information of the target operator. The operation authorization condition is used to indicate that the target operator needs to apply for operation permission in real time when performing certain operation steps in the target step sequence. For certain operation steps in the target step sequence, it is necessary to report and apply to the control center equipment of the target nuclear power unit for the next operation in real time, and then perform operation permission application processing according to the identity authentication information of the target operator.

[0117] In step S602 of some embodiments, the control center equipment checks whether the target operator has the qualifications and permissions to perform specific operations. If the conditions are met, the control center equipment will perform an operation permission review based on the identity authentication information of the target operator and generate an operation authorization instruction, so as to respond to the request of the target operator in real time. The operation authorization instruction is used to indicate that the target operator can perform the next operation step. In response to the target operator obtaining the operation authorization instruction, convey the step operation instruction information and the equipment monitoring parameters to the target operator. It is ensured that only the target operator who has been authorized and obtained the operation authorization instruction can perform key steps, thereby enhancing the safety and compliance of start-stop operations.

[0118] Through steps S601 to S602, through real-time operation authorization processing, it is ensured that the target operator has the necessary operation permissions when performing the start-up and shutdown operations of the nuclear power unit, improving the safety of the start-up and shutdown operations of the target nuclear power unit.

[0119] Please refer to Figure 7 , in some embodiments, after step S105, it may include but is not limited to steps S701 to S703:

[0120] Step S701, in response to obtaining a program interruption instruction from the target operator, pause the start-up and shutdown operation of the target unit equipment based on the target step sequence;

[0121] Step S702, in response to obtaining a program continuation instruction from the target operator, obtain the equipment monitoring parameters of the target unit equipment and perform an interruption status detection to obtain start-up and shutdown status information;

[0122] Step S703, in response to the start-up and shutdown status information meeting the interruption recovery condition, resume the start-up and shutdown operation of the target unit equipment based on the target step sequence.

[0123] In step S701 of some embodiments, in response to obtaining a program interruption instruction from the target operator, pause the start-up and shutdown operation of the target unit equipment based on the target step sequence. The program interruption instruction is used to represent a request instruction sent by the target operator to the control center equipment of the target nuclear power unit for pausing the start-up and shutdown operation of the target unit equipment. This mechanism allows the target operator to immediately stop the ongoing operation steps when encountering abnormal situations or needing to temporarily adjust the operation process of the target nuclear power unit. Or if there may be certain risks or problems in the subsequent start-up and shutdown operations of the target nuclear power unit, then this interruption function provides the target operator with control power to allow the target operator to inspect the target unit equipment so that no problems will occur in the subsequent start-up and shutdown operation process of the target nuclear power unit.

[0124] In step S702 of some embodiments, in response to obtaining a program continuation instruction from the target operator, obtain the equipment monitoring parameters of the target unit equipment and perform an interruption status detection to obtain start-up and shutdown status information. Thus, after the start-up and shutdown operation process of the target unit equipment is paused, a comprehensive assessment of the current state of the target unit equipment is carried out to ensure that the target unit equipment is in a safe and stable state before resuming the operation.

[0125] The program continuation instruction is used to represent a request instruction sent by the target operator to the control center equipment of the target nuclear power unit for resuming the start-up and shutdown operation of the paused target unit equipment. The start-up and shutdown status information is used to represent various parameter index information of the target unit equipment in the interrupted state, such as temperature, pressure, flow rate, etc.

[0126] In step S703 of some embodiments, in response to the start-stop status information satisfying the interruption recovery condition, resume the start-stop operation of the target unit equipment based on the target step sequence. When it is determined that all the parameter index information of the target unit equipment satisfies the interruption recovery condition, that is, the status of the target unit equipment meets the safety and operation requirements, resume the start-stop operation of the target unit equipment based on the target step sequence.

[0127] Through steps S701 to S703, the target operator can interrupt the start-stop operation when necessary, evaluate the status of the target unit equipment, and resume the start-stop operation when the interruption recovery condition is met. Thereby enhancing the flexibility of the start-stop operation and improving the safety and reliability of the start-stop operation.

[0128] Please refer to Figure 8 , in some embodiments, the target step sequence includes sequential control step procedures corresponding to each sub-step in the operation step information, and each sequential control step procedure is used to record the sub-step information of each sub-step of the target nuclear power unit regarding start-stop control. After step S105, it may include but is not limited to steps S801 to S808:

[0129] Step S801, construct a virtual unit model corresponding to the target nuclear power unit using digital twin technology;

[0130] Step S802, perform category division based on multiple sequential control step procedures of the target step sequence to determine multiple manual execution procedures and multiple automatic execution procedures;

[0131] Step S803, simulate the execution of the target step sequence based on the virtual unit model to obtain simulation execution data; where the simulation execution data includes first simulation data corresponding to the manual execution procedure and second simulation data corresponding to the automatic execution procedure;

[0132] Step S804, evaluate the first simulation data of each manual execution procedure based on a pre-configured first evaluation criterion to obtain first evaluation information;

[0133] Step S805, evaluate the second simulation data of each automatic execution procedure based on a pre-configured second evaluation criterion to obtain second evaluation information;

[0134] Step S806, update the manual execution procedure based on the first evaluation information to obtain a first updated procedure;

[0135] Step S807, update the automatic execution procedure based on the second evaluation information to obtain a second updated procedure;

[0136] Step S808, update the target step sequence based on the first updated procedure and the second updated procedure.

[0137] In step S801 of some embodiments, a virtual unit model highly corresponding to the target nuclear power unit is constructed using digital twin technology. The virtual unit model is used to accurately simulate the physical structure and operating parameters of the actual target nuclear power unit in a digital virtual environment and can reflect the operating state of the target nuclear power unit in real time. Through the virtual unit model, various operation processes can be simulated in a safe digital virtual environment, and the effects of various operation processes can be evaluated without directly operating on the actual target nuclear power unit, thus greatly reducing the operation risk.

[0138] In step S802 of some embodiments, multiple sequence control step procedures in the target step sequence are classified to distinguish which sequence control step procedures need to be manually executed and determined as manual execution procedures, and which sequence control step procedures can be automatically executed and determined as automatic execution procedures, which helps subsequent targeted evaluation and optimization of different types of sequence control step procedures.

[0139] In step S803 of some embodiments, the target step sequence is simulated and executed based on the virtual unit model, thereby obtaining simulation execution data. The simulation execution data is divided into two parts, the first simulation data corresponding to the manual execution procedure and the second simulation data corresponding to the automatic execution procedure. By simulating and executing the target step sequence through the virtual unit model, the execution data of each sequence control step procedure in the digital virtual environment can be collected, providing a basis for subsequent evaluation.

[0140] In steps S804 to S805 of some embodiments, the first simulation data of the manual execution procedure and the second simulation data of the automatic execution procedure are evaluated based on the pre-configured first evaluation criterion and second evaluation criterion respectively, and the first evaluation information and the second evaluation information are obtained respectively. The first evaluation information and the second evaluation information are used to represent the evaluation results of the first simulation data or the second simulation data. For the first simulation data of the manual execution procedure, the complexity, risk, and execution efficiency of the start-stop operation need to be concerned. For example, whether the start-stop operation executed manually is prone to errors and whether it can be optimized by automated means. For the second simulation data of the automatic execution procedure, the reliability and efficiency of the automated operation need to be concerned, check whether there are potential fault points or optimization spaces, and whether the security permissions need to be granted manually. However, whether it is a manual execution procedure or an automatic execution procedure, the impact of each sequence control step procedure on the safety of the target nuclear power unit should be evaluated, especially the operations involving safety-class equipment.

[0141] In steps S806 to S807 of some embodiments, based on the first evaluation information and the second evaluation information, the manual execution procedure and the automatic execution procedure are updated respectively. The update process may involve adjusting the order of operation steps, optimizing control logic, improving operation conditions, etc., to improve the efficiency and safety of operations. The updated manual execution procedure is called the first updated procedure, and the updated automatic execution procedure is called the second updated procedure. For the manual execution procedure, consider whether the operation process can be simplified by automated means to reduce human errors. For the automatic execution procedure, consider whether the control logic can be optimized to improve operation efficiency and reliability. When necessary, add additional safety inspection or confirmation steps to ensure the safety of start-stop operations.

[0142] In step S808 of some embodiments, the target step sequence is updated as a whole based on the first updated procedure and the second updated procedure, so as to ensure that the target step sequence, after considering the optimization of the manual execution procedure and the automatic execution procedure, can more efficiently and safely guide the target operator for the start-stop operation of the target nuclear power unit.

[0143] Through steps S801 to S808, by means of digital twin technology and the optimization method of simulation evaluation, a more scientific, safe and efficient guidance is provided for the start-stop operation of the target nuclear power unit, which helps to improve the operation efficiency and safety of the entire target nuclear power unit.

[0144] Please refer to Figure 9 , in some embodiments, the target step sequence includes multiple status checkpoints, the detailed step information includes the step execution conditions of each sequential control step procedure, and step S105 may include but is not limited to steps S901 to S902:

[0145] Step S901, in response to the target unit equipment running to the status checkpoint, perform a status detection on the target unit equipment to obtain status detection information;

[0146] Step S902, in response to the status detection information indicating that the target unit equipment meets the step execution conditions of the sequential control step procedure, convey the step sequence operation instruction information and the equipment monitoring parameters to the target operator to guide the target operator to perform the start-stop operation on the target unit equipment.

[0147] In step S901 of some embodiments, in response to the target unit equipment running to the status checkpoint, perform a status detection on the target unit equipment to obtain status detection information. The status checkpoint is a pre-set key node used to ensure that the target unit equipment is in the correct state before performing the next operation. Through status detection, the current operation parameters and status information of the target unit equipment can be obtained, such as key indicators such as temperature, pressure, and flow rate, so as to determine whether the target unit equipment meets the conditions for continuing to perform the start-stop operation.

[0148] In step S902 of some embodiments, in response to the status detection information, it is determined whether the target unit equipment meets the step execution conditions of the sequence control procedure. If the status detection information indicates that the target unit equipment meets the step execution conditions, the step sequence operation instruction information and the equipment monitoring parameters are conveyed to the target operator. Thus, the target operator can perform the start-stop operation safely and efficiently when the status of the target unit equipment permits.

[0149] Through steps S901 to S902, it is ensured that the target operator receives the step sequence operation instruction information and the equipment monitoring parameters when the status of the target unit equipment permits, so as to complete the start-stop operation of the target nuclear power unit safely and efficiently.

[0150] Please refer to Figure 10 , in some embodiments, after step S105, it may further include but is not limited to steps S1001 to S1005:

[0151] Step S1001, constructing a virtual unit model corresponding to the target nuclear power unit by using digital twin technology;

[0152] Step S1002, simulating the execution of the target step sequence based on the virtual unit model to obtain simulation execution data;

[0153] Step S1003, obtaining the actual operation data of the target nuclear power unit;

[0154] Step S1004, comparing the simulation execution data with the actual operation data to obtain deviation information;

[0155] Step S1005, performing equipment detection on the target nuclear power unit based on the deviation information.

[0156] In step S1001 of some embodiments, a virtual unit model highly corresponding to the target nuclear power unit is constructed by using digital twin technology. The virtual unit model is used to accurately simulate the physical structure and operation parameters of the actual target nuclear power unit in a digital virtual environment and can reflect the operation status of the target nuclear power unit in real time. Through the virtual unit model, various operation processes can be simulated in a safe digital virtual environment, and the effects of various operation processes can be evaluated without directly operating on the actual target nuclear power unit, thus greatly reducing the operation risk.

[0157] In step S1002 of some embodiments, the target step sequence is simulated and executed based on the virtual unit model, thereby obtaining the simulated execution data. The simulated execution data includes the detailed operation parameters and state changes of the nuclear power unit simulated by the virtual unit model when executing each operation step in the virtual environment, providing a basis for subsequent evaluation. By simulating and executing the target step sequence through the virtual unit model, the execution data of each sequential control step procedure in the digital virtual environment can be collected, thereby providing a basis for subsequent evaluation and optimization.

[0158] In step S1003 of some embodiments, the actual operation data of the target nuclear power unit is obtained. The actual operation data reflects the state data of the target nuclear power unit during actual operation, including key indicators such as temperature, pressure, and flow rate. By obtaining the actual operation data, the results of the simulated execution can be compared with the actual operation conditions, thereby evaluating the accuracy of the simulation and the effectiveness of the operation steps.

[0159] In step S1004 of some embodiments, a deviation information is obtained based on the comparison between the simulated execution data and the actual operation data. The deviation information reveals the differences between the simulated execution and the actual operation, which may include the execution time of the operation steps, the amplitude of parameter changes, and the differences in equipment states. By analyzing this deviation information, the problems that may exist in the operation steps of the target nuclear power unit during actual operation can be identified, thereby providing a direction for subsequent optimization.

[0160] In step S1005 of some embodiments, the equipment of the target nuclear power unit is detected based on the deviation information. Through detailed equipment detection, it is further confirmed whether the problems revealed by the deviation information are related to the actual state of the target unit equipment, so that problems can be discovered and processed in a timely manner to ensure the normal operation of the target unit equipment. For example, if there are large deviations between the simulated execution data and the actual operation data of the target unit equipment, it may indicate that there are performance degradation or failure risks in the target unit equipment.

[0161] In an embodiment of the present application, start-stop sequence control information of a target nuclear power unit is obtained; the start-stop sequence control information includes a unit sequence control sequence, and the unit sequence control sequence is used to record operation step information of the target nuclear power unit regarding start-stop control. In response to the target nuclear power unit obtaining a start-stop control signal, a target step sequence currently being executed is determined according to the start-stop control signal and the start-stop sequence control information. Step parsing is performed according to the target step sequence to generate step operation instruction information. Real-time monitoring is performed on target unit equipment corresponding to the target step sequence to obtain equipment monitoring parameters of the target unit equipment. The step operation instruction information and the equipment monitoring parameters are transmitted to a target operator to guide the target operator to perform start-stop operations on the target unit equipment. It can be seen from this that in the present application, the operation step information of the target nuclear power unit regarding start-stop control is recorded through the unit sequence control sequence, and by parsing the target step sequence currently being executed, clear step operation instruction information is generated and transmitted to the designated target operator together with the equipment monitoring parameters of the target unit equipment, so as to provide accurate guidance information for the unit personnel to perform start-stop operations on the target nuclear power unit.
