[0001] This invention relates to the technical field of nuclear power equipment management, and more specifically, to a method, apparatus, medium, and equipment for health assessment during the commissioning phase of nuclear power equipment. Background Technology

[0002] The commissioning and startup phase of nuclear power units is characterized by a large number of test items, complex transient conditions, and intertwined test logic, making equipment risk control during commissioning extremely difficult. Currently, the analysis and evaluation of tests on specific multi-system and unit transient operations are typically conducted by the test supervisor based on the technical requirements of the commissioning outline and test procedures, combined with transient process and historical test data. This monitoring process is discontinuous and lagging. In previous commissioning and startup tests of nuclear power units such as CPR and EPR, unplanned shutdowns and major equipment damage during the first transient test were common due to improper control parameter settings, mismatch between plant control protection and thermal-hydraulic characteristics, replacement of key regulating equipment, or major design improvements. This situation is particularly prominent in new projects using new technologies or with major design improvements, and represents a current technical challenge and pain point in the commissioning and startup of nuclear power units.

[0003] Therefore, for equipment in the commissioning phase, without an equipment health status assessment mechanism that considers the equipment's operating conditions, it is difficult to determine the impact of the equipment's operational health status and abnormal alarms at measurement points on the equipment's status throughout the entire commissioning phase.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] To achieve health status assessment of nuclear power equipment during the commissioning phase, and to incorporate full-condition data from the commissioning phase of key equipment as weights into the health assessment of equipment components and the overall health assessment of the equipment, this invention provides a health assessment method for nuclear power equipment during the commissioning phase. This health assessment method is based on full-condition data from the nuclear power equipment commissioning phase. Figure 1 A preferred embodiment of the health assessment method for the commissioning phase of nuclear power equipment provided by the present invention is shown.

[0019] Specifically, such as Figure 1 As shown, the health assessment method for the commissioning phase of this nuclear power plant includes the following steps: Step S10: Obtain alarm information from the test points on the device components during the debugging process.

[0020] Specifically, a equipment component is a relatively independent structural unit formed by the precise assembly and coordination of several parts or even smaller components. These structural units play a crucial role in the equipment, capable of independently performing a specific function or a series of interrelated operations. Equipment assemblies, on the other hand, represent a higher-level abstraction and integration of the various components, parts, and accessories that make up industrial equipment. The following uses the charging pump of a nuclear power plant vertical centrifugal pump as an example to categorize components. Specifically, such as... Figure 2 As shown, based on the definitions of components and assemblies, the charging pump can be divided into the following components: The pump body module includes the pump body assembly, bearing housing assembly, and coupling assembly. The motor module includes the support assembly and motor assembly. The auxiliary modules include: shaft seal assembly, instrumentation assembly, and piping assembly.

[0021] Step S20: Determine whether the measuring point has generated an alarm based on the alarm information.

[0022] Specifically, the method for determining whether an alarm has been generated at a measuring point based on alarm information can be directly determined from the alarm records in the alarm information; this invention does not impose any specific limitations.

[0023] Step S30: If so, determine the initial deduction items for the equipment components according to the first scoring method.

[0024] Optionally, in this embodiment of the invention, determining the initial deduction items for a device component according to the first scoring method includes: obtaining the number and level of alarms for the device component; quantifying the number and level of alarms to obtain the initial deduction items. Specifically, obtaining the number and level of alarms for the device component includes: obtaining the alarm severity; determining the importance of the measuring point; and determining the alarm level of the device component based on the alarm severity and importance.

[0025] Specifically, when alarms occur at measurement points on equipment components during commissioning, the number and level of alarms are quantified as initial deduction items. The number and level of alarms are determined through analysis and calculation of data recorded in the equipment commissioning anomaly identification alarm log. The alarm level is determined based on the severity of the alarm and the importance of the measurement point (i.e., the measurement point's importance). For example... Figure 3As shown. First, determine the importance of the measuring points based on their significance within the equipment components. The importance of measuring points is divided into three levels: 1, 2, and 3. For example, based on understanding the pump mechanism, pump temperature-related measuring points reflect equipment status less strongly than pump flow-related measuring points; therefore, the importance of pump temperature-related measuring points can be set to level 1, and the importance of pump flow-related measuring points can be set to level 2. Next, determine the alarm severity. The determination of alarm severity can be based on the following criteria: Algorithm exceeds limits: Set to Level 1 (i.e., Level I), which means the algorithm alarm (such as non-pure multivariate prediction anomaly identification algorithms, such as Autoassociative Kernel Regression or Multivariate State Estimation Technique). Algorithm severely exceeds limits: Set to Level 2 (i.e., Level II); Fixed threshold warning: Set to level 3 (i.e., level III); Fixed threshold high alarm: set to level 4 (i.e., level IV); Fixed threshold severe alarm (i.e., fixed threshold high alarm): set to level 5 (i.e., level V).

[0026] Then, the alarm level is determined based on the severity of the alarm and the importance of the measuring point. For example... Figure 3 As shown, the alarm severity for a measurement point with an importance level of 1 is "algorithm exceeding limits," and its alarm level is 1; the alarm severity for a measurement point with an importance level of 1 is "severe algorithm exceeding limits," and its alarm level is 1; the alarm severity for a measurement point with an importance level of 1 is "fixed threshold alarm," and its alarm level is 1; the alarm severity for a measurement point with an importance level of 1 is "fixed threshold high alarm," and its alarm level is 2; the alarm severity for a measurement point with an importance level of 1 is "fixed threshold high alarm," and its alarm level is 3. Similarly, the alarm severity for a measurement point with an importance level of 2 is "algorithm exceeding limits," and its alarm level is 1; the alarm severity for a measurement point with an importance level of 2 is "algorithm severely exceeding limits," and its alarm level is 1; the alarm severity for a measurement point with an importance level of 2 is "fixed threshold alarm," and its alarm level is 2; the alarm severity for a measurement point with an importance level of 2 is "fixed threshold high alarm," and its alarm level is 3; the alarm severity for a measurement point with an importance level of 2 is "fixed threshold high alarm," and its alarm level is 4. The measurement point importance level is 3, the alarm severity level is algorithm over-limit, and the alarm level is 1; the measurement point importance level is 3, the alarm severity level is algorithm severely over-limit, and the alarm level is 2; the measurement point importance level is 3, the alarm severity level is fixed threshold alarm, and the alarm level is 3; the measurement point importance level is 3, the alarm severity level is fixed threshold high alarm, and the alarm level is 4; the measurement point importance level is 3, the alarm severity level is fixed threshold high alarm, and the alarm level is 5.

[0027] Finally, after determining the alarm level, the initial deduction items can be calculated based on the deduction value corresponding to the alarm level and the number of alarms. The alarm levels and their deduction values ​​are shown in Table 1 below.

[0028] Table 1. Alarm Levels and Deduction Values The initial deductions for equipment components calculated using the first scoring method can be expressed by the following formula: ; In the formula, A represents the initial deduction item, and k is the alarm level. The deduction value is for alarm level i. This represents the number of alarms at alarm level i.

[0029] Step S40: If not, determine the initial deduction items for the equipment components according to the second scoring method.

[0030] Optionally, in this embodiment of the invention, determining the initial deduction items for the equipment components according to the second scoring method includes: acquiring data and anomaly identification alarm thresholds during the debugging process of the measurement points; and calculating the initial deduction items based on the data and anomaly identification alarm thresholds during the debugging process.

[0031] Specifically, if no alarm is detected at the measurement point, the data during the measurement point debugging process and the debugging anomaly identification alarm threshold are quantified as the initial deduction item. Specifically, the data and anomaly identification alarm threshold of the measurement point during the debugging process are first obtained, and then quantified based on the data and anomaly identification alarm threshold to obtain the initial deduction item. In this embodiment, the deduction value f for a single measurement point on the device component during the debugging process can be calculated using the following formula.

[0032] ; In the above formula, Indicates the real-time value of the measuring point; , These represent the lower and upper limits of the normal range, respectively. This represents the "health" index of the measured point value relative to the normal range, where 0 indicates that the alarm threshold has been reached, and 1 indicates that it is located at the midpoint of the normal range or the ideal value.

[0033] After obtaining the "health" index of the measurement point value relative to the normal range using the above formula, the deduction value f for a single measurement point on the equipment component can be calculated. The specific calculation formula is as follows: ; Based on the above formula, the initial deduction items for the device components can be calculated as follows: ; In the above formula, A represents the initial deduction item for the equipment component. This represents the maximum deduction value for each measuring point.

[0034] Step S50: Calculate the health assessment score of the equipment components based on the initial deduction items, the commissioning condition weight, and the commissioning system influence weight.

[0035] Optionally, in this embodiment of the invention, the calculation of the health assessment score of the equipment component based on the initial deduction item, the commissioning condition weight, and the commissioning system influence weight includes: determining the commissioning condition weight; determining the commissioning system influence weight; if an alarm occurs at the measuring point during commissioning, the health assessment score of the equipment component is calculated based on the initial deduction item, the commissioning condition weight, and the commissioning system influence weight calculated using the first calculation method; if no alarm occurs at the measuring point during commissioning, the health assessment score of the equipment component is calculated based on the initial deduction item, the commissioning condition weight, and the commissioning system influence weight calculated using the second calculation method.

[0036] The impact weight of the commissioning system is determined as follows: the performance evaluation weight of the equipment components is determined; the operation and maintenance record weight of the equipment components is determined; and the impact weight of the commissioning system is calculated based on the performance evaluation weight and the operation and maintenance record weight.

[0037] Preferably, the performance evaluation weight of the equipment component is determined by the following steps: obtaining the alarm frequency of the current component as a percentage of the total number of alarms of all components in the historical alarm record; obtaining the performance evaluation weight coefficient of the current component; and calculating the performance evaluation weight based on the alarm frequency and the performance evaluation weight coefficient.

[0038] Preferably, the maintenance record weight of the equipment component is determined by the following steps: calculating the maintenance ratio of the current component's maintenance frequency in the historical maintenance records to the total number of maintenance times of all components; obtaining the maintenance weight coefficient of the current component; and calculating the maintenance record weight based on the maintenance ratio and the maintenance weight coefficient.

[0039] Specifically, in this embodiment of the invention, the weight of the debugging condition can be quantified by the following method.

[0040] Analyze all operating condition types that occur during equipment commissioning. This involves analyzing the equipment commissioning operating condition records to determine all operating condition types, and then setting commissioning operating condition weights (defined as b) based on the following three scenarios. The weights are then normalized.

[0041] (1) When there are historical debugging alarm records of equipment of the same type or similar structure as the debugging equipment, the historical debugging alarm records are used as the basis for setting the working condition weight. The more historical alarms that occur under a certain debugging working condition, the greater the weight of that working condition.

[0042] (2) As can be seen from the pump mechanism, the probability of pump failure in unstable state is much higher than in stable state. Therefore, the weight of the working condition in unstable state during the commissioning process should be set larger, and the weight of the working condition in stable state during the commissioning process should be set smaller.

[0043] (3) If neither of the above two methods is feasible, then set all weights to 1. Then, the debugging working condition weights can be optimized by accumulating the historical debugging alarms of the equipment and combining them with the method in (1).

[0044] In this embodiment of the invention, the performance evaluation weights can be quantified using the following methods.

[0045] Calculate the alarm frequency of the current component relative to the total number of alarms for all components in the historical alarm records (defined as α). Let the component performance evaluation weight be c. The alarm frequency of the current component, as a percentage of the total number of alarms for all components in the historical alarm records, can be obtained and calculated based on the data from the equipment's historical anomaly identification alarm records.

[0046] In this embodiment of the invention, the weight of operation and maintenance records can be quantified by the following method.

[0047] Calculate the proportion (defined as β) of the current component's maintenance frequency in historical maintenance records relative to the total number of maintenance visits for all components. Let the weight of the component's maintenance record be d. The proportion of the current component's maintenance frequency in the historical maintenance records to the total number of maintenance times for all components can be obtained and calculated based on the equipment's historical maintenance records.

[0048] After calculating the performance evaluation weight c and the maintenance record weight, the impact weight of the debugging system can be calculated. Let the impact weight of the debugging system be e, then we can obtain: .

[0049] After determining the weights of the commissioning conditions and the impact weights of the commissioning system, the health assessment scores of the equipment components can be calculated, as follows: (1) If an alarm occurs at a test point on a device component during commissioning, the new deduction item will be updated as follows: (1); (2) If no alarm is triggered at the test point on the equipment component during the debugging process, the new deduction item will be updated as follows: (2); Ultimately, the health assessment scores for the equipment components were: (3); In equation (3), h is the health assessment score of a single device component. When there is an alarm at the measuring point on the device component during the commissioning process, A in equation (3) is obtained through equation (1); when there is no alarm at the measuring point on the device component during the commissioning process, A in equation (3) is obtained through equation (2).

[0050] The health assessment process for a single device component provided by this invention is as follows: Figure 4 As shown. Among them, Figure 4 In this context, the influence of the ISU system is the same as the influence of the debugging system, and the weight of the influence of the ISU system is the same as the weight of the influence of the debugging system.

[0051] Step S60: Calculate the overall health assessment score of the equipment based on the health assessment scores of each equipment component and their corresponding importance.

[0052] Specifically, in this embodiment of the invention, after calculating the health assessment scores of each device component during the commissioning phase through steps S10 to S50, the overall health assessment score of the device can be obtained based on the health assessment scores of each device component and their corresponding importance. The details are as follows: The equipment consists of multiple components; therefore, the overall health status of the equipment can be obtained by taking a weighted average of the health status of each component. The overall health status T of the equipment is derived from the weighted sum of the health statuses of each component: (4); In the above formula, m represents the number of equipment components; q represents the importance of the component, which can be given based on expert experience. ; Let represent the health assessment score of the j-th device component.

[0053] After the overall health assessment score of the equipment is calculated by formula (4), it can be mapped to the equipment health color, as shown in Table 2 below.

[0054] Represents 2. Equipment Overall Health Assessment Score Mapping Table refer to Figure 5 The present invention also provides a health assessment device for the commissioning phase of nuclear power equipment.

[0058] The component score calculation unit 504 is used to calculate the health assessment score of the equipment component based on the initial deduction items, the commissioning condition weight, and the commissioning system influence weight.

[0059] The equipment score calculation unit 505 is used to calculate the overall health assessment score of the equipment based on the health assessment scores of each equipment component and their corresponding importance.

[0060] Specifically, the specific coordination and operation process between the various units in the health assessment device during the commissioning phase of nuclear power equipment can be referred to the health assessment method during the commissioning phase of nuclear power equipment mentioned above, and will not be repeated here.

[0061] This invention innovatively employs an equipment health assessment method that considers the impact of equipment operating conditions to evaluate the health status of critical nuclear power equipment during the commissioning phase, thereby demonstrating the health status of the equipment during commissioning. The equipment health assessment is influenced by parameters such as component importance, measurement point importance, commissioning condition weight, performance evaluation weight, and maintenance record weight. This results in different health assessments for the same type of alarm at different measurement points. Compared to previous alarm systems, this allows users to focus on alarms with critical parameters, while alarms with non-critical parameters have little impact on equipment health.
