During actual operation, various abnormalities and emergencies may occur due to factors such as equipment aging, operational errors, and external environmental influences.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0055] An embodiment of the present invention provides a method for responding to an abnormality in a nuclear power unit. The method is applied to a nuclear power unit abnormality response system. The nuclear power unit abnormality response system includes a client and a server. The client and the server communicate via a network to implement real-time monitoring and precise analysis of the operating status of the nuclear power unit, thereby improving the accuracy and efficiency of abnormal responses. The client, also known as the user end, refers to a program corresponding to the server that provides local services to clients. The client can be installed on, but is not limited to, various personal computers, laptops, smartphones, and tablets. The server can be implemented as a standalone server or a server cluster consisting of multiple servers.

[0056] In one embodiment, if Figure 1 As shown, a method for abnormal response of a nuclear power unit is provided, comprising the following steps:

[0057] S10, determining whether an abnormality occurs in the nuclear power unit;

[0058] S20. If an abnormality occurs in the nuclear power unit, obtain a target situation in which the abnormality occurs in the nuclear power unit.

[0059] In one embodiment, a nuclear power unit is composed of multiple devices and systems, including but not limited to a reactor, a cooling system, a control system, a steam generator, and other equipment. Due to equipment failure, operational errors, or external factors, abnormalities may occur in the nuclear power unit. When an abnormality occurs in the nuclear power unit, it is necessary to obtain the target situation of the abnormality of the nuclear power unit, which includes abnormal events and external factors. Among them, abnormal events refer to the situation where key equipment or systems in the nuclear power plant malfunction or fail, such as equipment aging, design defects, operational errors, external events, etc., which can be obtained by real-time monitoring of key parameters through various sensors and monitoring systems, and the specific present invention does not limit them.

[0060] S30, determining a target response organization based on the target situation, and determining a target personnel based on the determined target response organization, so that the target personnel collect and analyze the fault information of the nuclear power unit according to a preset information collection form to obtain a fault analysis result;

[0061] S40: After receiving the fault analysis result, determine whether to adjust the target response organization according to the fault analysis result.

[0062] In one embodiment, after obtaining a target abnormality situation of a nuclear power unit, a target response organization is further determined based on the obtained target situation. The target response organization can be an institution or organization for responding to and handling abnormal situations of the nuclear power unit. The target response organization includes multiple target personnel with relevant professional knowledge and skills, such as operators, technicians, safety personnel, and data analysts. After the target response organization is determined, target personnel suitable for handling the target situation are determined based on target information corresponding to the target personnel in the target response organization stored in the nuclear power unit abnormality response system. The target personnel can be one or more target personnel, and the specific details are not limited by the present invention. After the target personnel are determined, it is necessary to receive the fault analysis results obtained by the target personnel collecting and analyzing the nuclear power unit fault information according to a preset information collection form. The preset collection form includes equipment history records, internal inspection records, power plant parameter records, trend chart records, operation logs, maintenance records, historical analysis reports, emergency safety reports, safety reports, safety measures reports, technical specification documents, and equipment failure reports. The fault analysis results include, but are not limited to, the type of fault, specific cause, fault mode, and impact range. By receiving these fault analysis results, the development trend of the nuclear power unit's anomaly can be determined, allowing for timely adjustments to the target response organization. This approach avoids the traditional tedious process of holding meetings to discuss and determine the target response organization, improves the efficiency and accuracy of the target response organization, and maximizes the safe operation of the nuclear power plant.

[0063] For example, if the fault analysis results indicate a widespread impact and difficulty in handling, more professional personnel and technical support will be required to address the situation. In this case, the target response organization will be adjusted accordingly based on the specific situation to ensure sufficient resources and capabilities to handle the current fault. In addition, if an accident or natural disaster occurs, an emergency state will be entered, and all target response organizations will respond. It should be noted that the above is only an example and is not limited to the specific present invention.

[0064] In summary, an embodiment of the present invention provides a method for responding to an abnormality in a nuclear power unit, by determining whether an abnormality has occurred in the nuclear power unit. If an abnormality has occurred, the target situation in which the abnormality has occurred is obtained. Then, based on the target situation in which the abnormality has occurred, a target response organization for handling the abnormality is determined, and corresponding target personnel are determined from the target response organization, so that the target personnel collect information about the nuclear power unit fault according to a pre-set information collection form, and analyze the information to obtain a fault analysis result. Finally, after receiving the fault analysis result, it is determined whether the previously determined target response organization needs to be adjusted based on the fault analysis result. Through the above method, the problem that traditional abnormal response mainly relies on manual operation and experience judgment, resulting in slow response speed, is solved, and it is ensured that when an abnormality occurs in the nuclear power unit, personnel can be organized quickly and effectively to handle the fault, and the target response organization can be adjusted in time based on the fault analysis result, thereby improving processing efficiency.

[0065] In one embodiment, if Figure 2 As shown, in step S30, the target situation includes abnormal events and external factors, and the target response organization includes a first target response organization and a second target response organization. That is, determining the target response organization according to the target situation includes the following steps:

[0066] S31. Determine the risk type of the abnormal event, where the risk type includes target equipment failure and major transient state of the unit.

[0067] In one embodiment, the risk types of abnormal events in a nuclear power plant include target equipment failure and major unit transients. Target equipment failure refers to the failure or malfunction of key equipment in a nuclear power plant, including but not limited to steam turbine generators, transformers, transmission components, and high-voltage switchgear. Major unit transients refer to sudden, significant changes or events during the operation of a nuclear power plant, such as rapid changes in nuclear reactor power or abnormal system parameters.

[0068] S32: When the target situation is an external factor, and / or the risk type is a target device failure, determining that the target response organization is the first target response organization;

[0069] S33. When the risk type is a major transient state of the unit, determine that the target response organization is the second target response organization.

[0070] In one embodiment, when the target situation is an external factor, or the risk type is a target equipment failure, the target response organization is determined to be the first target response organization. The first target response organization generally has the ability to handle general and common failures and can respond quickly and effectively. However, if the risk type is determined to be a major transient of the unit, the target response organization is determined to be the second target response organization. The second target response organization generally has a higher technical level and stronger emergency response capabilities, and can professionally handle and respond to major transient anomalies of the nuclear power plant unit to ensure the safe and stable operation of the nuclear power plant. Based on the specific target situation, the target response organization can be quickly determined to ensure that the nuclear power unit can receive timely and effective treatment when an anomaly occurs. At the same time, it avoids the traditional method of convening a meeting to discuss and analyze the target situation when a failure occurs, and then determining the corresponding target response organization. This improves the efficiency and accuracy of the nuclear power unit's abnormal response.

[0071] In one embodiment, step S30, i.e., determining the target personnel according to the determined target response organization, includes the following steps:

[0072] S34. Selecting personnel in the target response organization who are working during preset working hours as target personnel to be confirmed;

[0073] S35. Determine the target information of the target person to be confirmed, and determine the target person based on the target information, wherein the target information includes position and major.

[0074] In one embodiment, personnel working during preset working hours are selected as target personnel to be confirmed. This is done to filter out personnel from the target response organization who are available during the preset working time period. The preset working time period can be set based on actual conditions and specific needs, such as a normal workday, a specific time period, or a specific shift, though this is not specifically defined in the present invention. This approach ensures that the selected target personnel can promptly collect and analyze fault information according to the preset fault information collection form, thereby improving overall efficiency. Target information for the target personnel to be confirmed is further determined, including position, major, and other information, though this is not specifically defined in the present invention. This information is intended to more accurately assess whether the target personnel possess the ability to collect and analyze fault information. Then, based on the determined major and position information, the target personnel are identified. Further screening and matching of target personnel for fault information collection and analysis can be performed to determine the most suitable target personnel. This process allows for more accurate identification of the target response organization and the most suitable target personnel for fault information collection and analysis when an anomaly occurs, providing strong support for subsequent adjustments to the target response organization.

[0075] In one embodiment, that is, in step S32, the target equipment includes a steam turbine generator set, a transformer, a transmission component, and a high-voltage switch station, and the external factors include a drum network blockage and a typhoon. That is, when the target situation is an external factor and / or the risk type is a target equipment failure, determining that the target response organization is a first target response organization includes the following steps:

[0076] S321. When any target device of the steam turbine generator set, the transformer, the transmission component and the high-voltage switch station fails, or the drum-network pressure difference is greater than a preset value and exceeds a preset time, or the typhoon forecast wind speed is greater than a first preset wind speed and the measured average wind speed is greater than a second preset wind speed, the target response organization is determined to be the first target response organization, wherein the drum-network pressure difference is the pressure difference between the blower inlet and outlet.

[0077] In one embodiment, by real-time monitoring of the status of target equipment, for example, real-time monitoring of various parameters of the target equipment, it is determined whether the target equipment has failed, that is, whether any target equipment such as a steam turbine generator set, a transformer, a transmission component, and a high-voltage switch station has failed; or when the drum-to-grid pressure difference exceeds a preset value and lasts for a preset period of time, that is, when the drum-to-grid pressure difference exceeds the preset value and persists for a period of time, indicating an abnormality in the blower system, where the drum-to-grid pressure difference is the pressure difference between the blower inlet and outlet; or when the typhoon forecast wind speed exceeds a first preset wind speed and the measured average wind speed exceeds a second preset wind speed, that is, when the typhoon forecast wind speed exceeds the first preset wind speed and the measured average wind speed also exceeds the second preset wind speed, the target response organization is determined to be the first target response organization. By determining whether the target equipment has failed or exceeded the warning conditions, the target response organization can be automatically determined, thereby improving the efficiency of handling abnormalities in nuclear power units.

[0078] For example, when the main bearing temperature of the steam turbine generator set suddenly rises to 90°C within 1 minute. Or, the pressure difference between the blower inlet and outlet suddenly increases, exceeds the preset value by more than 30%, and lasts for more than the preset time of 30 minutes. Or, according to the forecast of the meteorological department, the predicted wind speed of the upcoming typhoon is 25 m / s, and the first preset wind speed of the nuclear power plant is 20 m / s. At the same time, the measured average wind speed is 16 m / s, and the second preset wind speed of the nuclear power plant is 15 m / s, then the target response organization is determined to be the first target response organization. It should be noted that the above is only an example, and the specific present invention is not limited thereto.

[0079] In one embodiment, in step S33, the significant transient state of the unit includes reactor power change, pressure change, flow change, and temperature change. That is, when the risk type is significant transient state of the unit, determining that the target response organization is one of the second target response organizations includes the following steps:

[0080] S331. When the reactor power is greater than the first preset power or less than the second preset power within the first preset time, or the pressure is greater than the first preset pressure or less than the second preset pressure within the second preset time, or the flow is greater than the first preset flow or less than the second preset flow within the third preset time, or the temperature is greater than the first preset temperature or less than the second preset temperature within the fourth preset time, the target response organization is determined to be the second target response organization.

[0081] In one embodiment, when the reactor power is greater than the first preset power within the first preset time; or the reactor power is less than the second preset power within the first preset time; or the pressure is greater than the first preset pressure within the second preset time; or the pressure is less than the second preset pressure within the second preset time; or the flow is greater than the first preset flow within the third preset time; or the flow is less than the second preset flow within the third preset time; or the temperature is greater than the first preset temperature within the fourth preset time; or the temperature is less than the second preset temperature within the fourth preset time; then the target response organization is determined to be the second target response organization. By setting the above conditions, the corresponding target response organization can be determined according to the changes in reactor power, pressure, flow or temperature within different preset times, so that appropriate measures can be taken to deal with possible problems, and the response efficiency of the target response organization is also improved.

[0082] For example, the following conditions are set:

[0083] During the first preset time: the first preset power is P1, and the second preset power is P2;

[0084] During the second preset time: the first preset pressure is P1 压 , the second preset pressure is P2 压 ;

[0085] During the third preset time: the first preset flow rate is Q1, and the second preset flow rate is Q2;

[0086] During the fourth preset time: the first preset temperature is T1, and the second preset temperature is T2.

[0087] Now, if one of the following happens:

[0088] The reactor power is greater than the first preset power within the first preset time (P>P1);

[0089] The reactor power is less than the second preset power (P <P2);

[0090] The pressure is greater than the first preset pressure (P 压>P1 压 );

[0091] The pressure is less than the second preset pressure (P 压 <P2 压 );

[0092] The flow rate is greater than the first preset flow rate within the third preset time (Q>Q1);

[0093] The flow rate is less than the second preset flow rate (Q <Q2);

[0094] The temperature is greater than the first preset temperature within a fourth preset time (T>T1);

[0095] The temperature is lower than the second preset temperature (T <T2);

[0096] Then, the target response organization will be determined as the second target response organization.

[0097] It should be noted that the first preset time, the second preset time, the third preset time, and the fourth preset time can be the same or different, and the present invention does not limit this. For example, the first preset time can be 1 minute, 5 minutes, 10 minutes, or other time periods, and so on. To avoid repetition, the present invention will not elaborate on this. Similarly, other preset conditions can also be set according to actual circumstances, and the present invention will not elaborate on them one by one.

[0098] In one embodiment, if Figure 3 As shown, in step S40, that is, determining whether to adjust the target response organization according to the fault analysis result, includes the following steps:

[0099] S41. Input the fault analysis result into a risk prediction model to obtain a risk prediction result output by the risk prediction model, where the risk prediction model is trained based on historical data of the fault analysis result.

[0100] In one embodiment, the information contained in the fault analysis results is extracted and converted into a form that can be recognized by the risk prediction model, such as numerical values, features, etc. These fault analysis results include but are not limited to the type of fault, specific cause, fault mode and scope of impact, etc. The data obtained after the conversion will be input into the risk prediction model, and then a risk prediction result will be output to achieve the prediction and evaluation of future risks. Among them, the risk prediction model is trained based on the historical data of the fault analysis results and the treatment measures. The risk prediction result may include but is not limited to information such as risk level, probability of future faults, and recommendations on whether to adjust the current target response organization. This information can help relevant target users understand the future risk status represented by the current fault analysis results and determine whether to adjust the current target response organization. In this way, the traditional tediousness of manually discussing whether to adjust the response organization through meetings is saved, and whether to adjust the target response organization can be determined more accurately and efficiency is improved.

[0101] In one embodiment, the risk prediction model can be trained in the following manner:

[0102] Obtain historical data from fault analysis results, including the type of fault, specific cause, fault mode and impact scope, and other relevant information;

[0103] Preprocessing the historical data in the fault analysis results to obtain processed target data, wherein the preprocessing includes removing duplicate data, processing missing values, processing outliers, and performing data conversion and standardization;

[0104] The prediction model is trained based on the processed target data, and the risk prediction model is obtained after the training is completed. The training process includes dividing the data into a training set and a validation set, adjusting model parameters, and evaluating model performance.

[0105] For example, past failure data is collected from a nuclear power plant's operating records and fault database, including information such as the failure type (e.g., pipeline leak, control system failure), specific cause (e.g., equipment aging, operational error), failure mode, and impact range. This data is then preprocessed, including removing duplicate data, handling missing values ​​(e.g., using interpolation), addressing outliers (e.g., smoothing or removing outlier data points), performing data transformations (e.g., feature extraction for time series data), and standardization (e.g., scaling the data to a similar range). The preprocessed data is then divided into training and validation sets. Appropriate machine learning algorithms (e.g., support vector machines, random forests) are then used to train the data, adjust model parameters to improve prediction accuracy, and evaluate model performance (e.g., precision and recall). Through this process, a risk prediction model for nuclear power unit anomalies can be established, enabling early decisions on whether to switch to a target response organization to ensure safe and stable operation of the nuclear power plant.

[0106] It should be noted that the above is only an example and the present invention is not limited thereto.

[0107] S42. Send the risk prediction result to a risk result output page, so that a target user can input a control operation on the risk result output page to obtain a target instruction, wherein the target user includes multiple users.

[0108] In one embodiment, the risk prediction results are sent to a risk result output page via some means (e.g., network transmission, database update, or other means). This page is an interface for displaying the risk prediction results, allowing target users to intuitively understand the current risk status and recommendations. Target users, including multiple users such as the shift supervisor, safety supervisor, engineer, and the leaders and deputy leaders of the first and second target response organizations, can view the risk prediction results on this risk result output page. Based on the risk prediction results, they can perform corresponding control operations on the page based on their respective expertise and responsibilities. These control operations can include approving or disapproving the adjustment of the current target response organization. Once the target user completes the control operation, the nuclear power unit abnormal response system generates target instructions based on these operations, indicating whether the adjustment of the current target response organization is approved. In this way, risk prediction results can not only be promptly and accurately communicated to multiple target users, but also be translated into specific response measures through their actions, thereby ensuring the safe operation of the nuclear power plant or related facilities. This avoids the inefficient processing caused by traditional meetings and ensures the synergy and efficiency of risk management and emergency response.

[0109] S43: After receiving target instructions corresponding to multiple target users, obtain weight values ​​corresponding to the target users.

[0110] In one embodiment, after receiving target instructions corresponding to multiple target users, it is necessary to obtain the weight values ​​corresponding to the corresponding target users. The setting of the target user weight values ​​is to ensure the professional ability and importance of each target user. For example, the shift leader, as the overall person in charge of the target response organization, has the decision-making ability to adjust the target response organization. Therefore, his weight value may be relatively high, such as 0.5; and the engineer, as technical support and advice, has a relatively high weight value, for example, 0.6; and the weight values ​​of the security director, the first and second target response organization leaders and deputy leaders may be relatively low, which can be 0.4, 0.4, and 0.3 respectively. By obtaining the weight value of the target user corresponding to the output target instruction, a data basis is provided for the subsequent determination of whether to adjust the current target response organization. It should be noted that the above weight value is only an example, and can be set specifically according to actual conditions, and the present invention does not limit it.

[0111] S44. Determine whether to adjust the current target response organization based on the target instructions corresponding to the multiple target users and the weight values ​​corresponding to the target users.

[0112] In one embodiment, the multiple target users may include target users A, B, C, D, and E. The target instruction corresponding to target user A may be the first target instruction, the target instruction corresponding to target user B may be the second target instruction, the target instruction corresponding to target user C may also be the first target instruction, the target instruction corresponding to target user D may also be the second target instruction, and the target instruction corresponding to target user E may also be the second target instruction. The first target instruction may indicate agreement to adjust the current target response organization, and the second target instruction may indicate disagreement to adjust the current target response organization. The weight values ​​corresponding to target users A, B, C, D, and E may be 0.5, 0.6, 0.3, 0.4, and 0.7, respectively, although the present invention does not limit this. Then, the weight values ​​of the target instructions corresponding to the target users agreeing to adjust the current target response organization and the weight values ​​of the target instructions disagreeing to adjust the current target response organization are added together and compared to determine whether to adjust the current target response organization. This judgment ensures the accuracy and efficiency of decision-making. At the same time, this method also reflects the advantages of collaborative decision-making, enabling better utilization of the professional strengths of each target user and improving the overall ability to respond to risks. It should be noted that the above is only an example and the present invention is not limited thereto.

[0113] In one embodiment, if Figure 4 As shown, in step S44, that is, determining whether to adjust the current target response organization based on the target instructions corresponding to the multiple target users and the weight values ​​corresponding to the target users, includes the following steps:

[0114] S441: When the target instruction is a first target instruction, obtain weight values ​​of all the first target instructions corresponding to the target users;

[0115] S442: Calculate a first calculation result based on the weight values ​​of all target users corresponding to the first target instructions;

[0116] S443: When the target instruction is a second target instruction, obtain weight values ​​of all the second target instructions corresponding to the target users;

[0117] S444. Calculate a second calculation result based on the weight values ​​of all target users corresponding to the second target instructions;

[0118] S445: Determine whether to adjust the current target response organization according to the magnitudes of the first calculation result and the second calculation result.

[0119] Specifically, the nuclear power plant abnormality response system first checks whether the current target instruction is the first or second target instruction. If it is the first target instruction, the nuclear power plant abnormality response system obtains the weight values ​​of all related target users and performs a calculation based on these weight values ​​to obtain a first calculation result. If it is the second target instruction, the nuclear power plant abnormality response system obtains the weight values ​​of all related target users and performs a calculation based on these weight values ​​to obtain a second calculation result. Finally, the nuclear power plant abnormality response system compares the first and second calculation results to determine whether the current target response organization needs to be adjusted. If the first calculation result is greater, the current target response organization should be adjusted. Conversely, if the second calculation result is greater, the current target response organization should not be adjusted. If the two calculation results are the same, the current target response organization is not adjusted. The purpose is to determine whether the current target response organization needs to be adjusted based on the different target instructions and the weight values ​​of the related users, as well as the comparison of the calculation results, so as to better handle the current nuclear power plant abnormality.

[0120] Exemplarily, it is assumed that the first target instruction is OI1, the second target instruction is OI2, the weight values ​​of the target users are W1 and W2, the first calculation result is CR1, and the second calculation result is CR2.

[0121] When OI_1 is the first target instruction:

[0122] Get the weight value of all OI1 corresponding target users: W1

[0123] Calculate the first calculation result:

[0124] When OI2 is the second target instruction:

[0125] Get the weight value of all OI2 corresponding target users: W2

[0126] Calculate the second calculation result:

[0127] For example, for OI1:

[0128] The target user A has a weight of 0.3

[0129] The target user B has a weight of 0.5

[0130] The target user C weight is 0.3

[0131] Then W1 = [0.3, 0.5, 0.3]

[0132] For OI2:

[0133] The target user D weight is 0.4

[0134] The target user E weight is 0.4

[0135] The target user's F weight value is 0.2

[0136] Then W2 = [0.4, 0.4, 0.2]

[0137] For OI1: The first calculation result is CR1 = 0.3 + 0.5 + 0.3 = 1.1

[0138] For OI2: The second calculation result is CR2 = 0.4 + 0.4 + 0.2 = 1.0

[0139] It is found that the first calculation result is greater than the second calculation result, indicating that the current target response organization agrees to adjust. By calculating and comparing the results through the weight values ​​of different target instructions and their corresponding target users, more detailed and scientific decisions can be made. Not only can the opinions and importance of different target users be comprehensively considered, but the basis for decision-making can also be quantified through the calculation results, thereby improving the accuracy and efficiency of decision-making. It should be noted that the above is only an example and is not limited to the specific present invention.

[0140] In one embodiment, step S445, that is, determining whether to adjust the current target response organization based on the magnitude of the first calculation result and the second calculation result, includes the following steps:

[0141] S4451: When the target response organization is the first target response organization and the first calculation result is greater than the second calculation result, adjust the first target response organization to the second target response organization;

[0142] S4452. When the target response organization is the first target response organization and the first calculation result is less than the second calculation result, the target response organization is maintained as the first target response organization.

[0143] In one embodiment, when the target response organization is confirmed as the first target response organization and the first calculation result is greater than the second calculation result, the nuclear power plant abnormal response system will adjust the target response organization to the second target response organization. On the other hand, when the target response organization is confirmed as the first target response organization and the first calculation result is less than the second calculation result, the nuclear power plant abnormal response system will maintain the target response organization as the first target response organization.

[0144] It should be noted that the target response organization may also include a third target response organization, which can respond to accidents or natural disasters. When the target response organization is the second target response organization and the first calculation result is greater than the second calculation result, the second target response organization is adjusted to the third target response organization; otherwise, no adjustment is made. Furthermore, modulation can be directly made from the first target response organization to the third target response organization, and the present invention does not limit this in detail.

[0145] In one embodiment, that is, in step S40, after receiving the fault analysis result, the following steps are further included:

[0146] S45. Determine the fault mode according to the fault analysis result;

[0147] S46: Determine whether to activate an emergency repair team based on the fault mode.

[0148] In one embodiment, a failure mode is determined based on the fault analysis results. This failure mode includes, but is not limited to, hardware failures (including those caused by circuit component damage, connection problems, and device aging); software failures (including those caused by program errors, logic errors, and memory overflows); communication failures (including those caused by network connection issues, communication protocol errors, and signal interference); power failures (including those caused by voltage instability, power outages, and power overloads); environmental failures (including those caused by environmental factors such as excessive temperature, excessive humidity, and dust accumulation); and human error (including those caused by human factors such as misoperation, improper operation, and improper maintenance). After determining the failure mode, the system's impact and urgency are assessed to determine whether to activate a repair team. For example, if a human error or environmental failure occurs, the repair team is not activated; if a software failure, hardware failure, or power failure occurs, the repair team is activated. This determination reduces personnel waste, avoids unnecessary repair operations, and improves resource utilization efficiency. The corresponding emergency repair team is activated only when it is really needed, ensuring the effective use of emergency repair resources and the timeliness of fault handling, ensuring that the facility can respond quickly and effectively when a fault occurs, and ensuring the safe and stable operation of the facility.
