DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] An embodiment of the present invention provides a method for abnormal response of a nuclear power unit, which is applied in an abnormal response system of a nuclear power unit. The abnormal response system of a nuclear power unit includes a client and a server. The client communicates with the server through a network to realize real-time monitoring and accurate analysis of the operating status of the nuclear power unit, and improve the accuracy and efficiency of abnormal response. Among them, the client, also known as the user end, refers to a program corresponding to the server that provides local services to customers. The client can be installed on, but not limited to, various personal computers, laptops, smart phones and tablets. The server can be implemented with an independent server or a server cluster consisting of multiple servers.

[0020] In one embodiment, if Figure 1 As shown, a method for abnormal response of a nuclear power unit is provided, comprising the following steps: S10, determining whether an abnormality occurs in the nuclear power unit; S20. If an abnormality occurs in the nuclear power unit, obtain a target situation in which the abnormality occurs in the nuclear power unit.

[0021] In one embodiment, a nuclear power unit is composed of a plurality of devices and systems, specifically including but not limited to a reactor, a cooling system, a control system, a steam generator, and other equipment. The nuclear power unit may be abnormal due to equipment failure, operating error, or external factors. When an abnormality occurs in a nuclear power unit, it is necessary to obtain a target situation in which the nuclear power unit is abnormal, and the target situation includes abnormal events and external factors. Among them, an abnormal event refers to a situation in which a key device or system in a nuclear power plant fails or fails, such as equipment aging, design defects, operating 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 is not limited.

[0022] S30, determining a target response organization according to the target situation, and determining a target person according to the determined target response organization, so that the target person collects and analyzes the fault information of the nuclear power unit according to a preset information collection form to obtain a fault analysis result; S40: After receiving the fault analysis result, determine whether to adjust the target response organization according to the fault analysis result.

[0023] In one embodiment, after obtaining the target situation of abnormality of the nuclear power unit, further according to the obtained target situation, a target response organization is determined, which can be an institution or organization for abnormal situation response and fault handling of the nuclear power unit, and the target response organization includes multiple target personnel, and the target personnel have relevant professional knowledge and skills, such as operating personnel, technical personnel, safety personnel and data analysis personnel. After the target response organization is determined, according to the target information corresponding to the target personnel in the target response organization stored in the abnormal response system of the nuclear power unit, the target personnel who meet the requirements of handling the target situation are determined, and the target personnel can be one or more, and the specific present invention is not limited. After the target personnel are determined, it is necessary to receive the fault analysis results obtained by the target personnel collecting the fault information of the nuclear power unit according to the preset information collection form and analyzing the fault information of the nuclear power unit, and 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, etc. By receiving the fault analysis results, the abnormal development trend of the nuclear power unit can be obtained, and the target response organization can be adjusted in time. Through the above method, the traditional need to hold a meeting for discussion and then determine the cumbersomeness of the target response organization is avoided, the response efficiency and accuracy of the target response organization are improved, and the safe operation of the nuclear power plant is guaranteed to the greatest extent.

[0024] For example, when the fault analysis result shows that the fault has a wide impact and is difficult to handle, more professionals and technical support are needed to deal with it. In this case, the target response organization is adjusted accordingly according to the specific situation to ensure that there are sufficient resources and capabilities to handle the current fault. In addition, if an accident occurs or due to a natural disaster, an emergency state is entered and all target response organizations will respond. It should be noted that the above is only an example and the specific present invention is not limited thereto.

[0025] In summary, an embodiment of the present invention provides a method for responding to an abnormality of a nuclear power unit, by judging whether an abnormality occurs in the nuclear power unit. If an abnormality occurs, the target situation of the abnormality is obtained. Then, according to the target situation of the abnormality, a target response organization for handling the abnormality is determined, and a corresponding target personnel is determined from the target response organization, so that the target personnel collects information about the nuclear power unit fault according to a pre-set information collection form, and analyzes it 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 according to the fault analysis result. Through the above method, the problem that the traditional abnormal response mainly relies on manual operation and experience judgment, resulting in a 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 according to the fault analysis result, thereby improving the processing efficiency.

[0026] 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, according to the target situation, determining the target response organization includes the following steps: S31. Determine the risk type of the abnormal event, where the risk type includes target equipment failure and major transient state of the unit.

[0027] In one embodiment, the risk types of abnormal events in a nuclear power unit include target equipment failure and unit major transients. Target equipment failure refers to the failure or failure of key equipment in a nuclear power plant. The target equipment includes but is not limited to steam turbine generator sets, transformers, power transmission components, and high-voltage switch stations. Unit major transients refer to sudden major changes or events that occur during the operation of a nuclear power unit, such as rapid changes in nuclear reactor power or abnormal system parameters.

[0028] 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; 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.

[0029] 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, which usually has the ability to handle general and common failures, and can respond quickly and handle them effectively. However, if the risk type is determined to be a major transient of the unit, the target response organization will be determined to be the second target response organization, which usually has a higher technical level and stronger emergency handling 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. According to the specific target situation, the target response organization can be quickly determined to ensure that the nuclear power unit can be handled promptly and effectively when an abnormality occurs. At the same time, it avoids the traditional need to convene a meeting on duty to discuss and analyze the target situation when a failure occurs, and then determine the corresponding target response organization, which is cumbersome, thereby improving the efficiency and accuracy of the abnormal response of the nuclear power unit.

[0030] In one embodiment, step S30, that is, determining the target personnel according to the determined target response organization, includes the following steps: S34, selecting personnel in the target response organization during preset working hours as target personnel to be confirmed; S35. Determine the target information of the target person to be confirmed, and determine the target person according to the target information, wherein the target information includes position and major.

[0031] In one embodiment, personnel at preset working hours are selected as target personnel to be confirmed, the purpose is to screen out personnel available within the preset working time period from the target response organization, wherein the preset working time can be set according to actual conditions and specific needs, such as normal working days, specific time periods or specific shifts, etc., which are not limited in the specific present invention. Through the above-mentioned method, it can be ensured that the selected target personnel can collect and analyze fault information in accordance with the preset fault information collection form in a timely manner, thereby improving the overall efficiency. Further determine the target information of the target personnel to be confirmed, the target information includes positions, majors and other information, which are not limited in the specific present invention, and the purpose is to more accurately evaluate whether the target personnel have the ability to collect and analyze fault information. Then, the target personnel are determined according to the determined professional and position information, and the target personnel for collecting and analyzing fault information can be further screened and matched to determine the most suitable target personnel. Through the above-mentioned process, the target response organization can be more accurately determined when an abnormality occurs, and the most suitable target personnel for fault information collection and analysis can be determined, which provides strong support for whether to adjust the target response organization in the future.

[0032] 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: S321. When any target equipment 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.

[0033] In one embodiment, by real-time monitoring of the state of the target device, for example, real-time monitoring of various parameters of the target device, it is determined whether the target device fails, that is, whether any target device such as a steam turbine generator set, a transformer, a power transmission component, and a high-voltage switch station fails; or the drum network pressure difference is greater than a preset value and exceeds a preset time, that is, when the drum network pressure difference exceeds the preset value and lasts for a period of time, it indicates that there is an abnormality in the blower system, wherein the drum network pressure difference is the pressure difference between the blower inlet and outlet; the typhoon forecast wind speed is greater than the first preset wind speed and the measured average wind speed is greater than the second preset wind speed, that is, when the typhoon forecast wind speed exceeds the first preset wind speed, and the measured average wind speed is also greater than the second preset wind speed, the target response organization is determined to be the first target response organization. By determining whether the target device fails or exceeds the warning conditions, the target response organization can be automatically determined, thereby improving the processing efficiency when an abnormality occurs in the nuclear power unit.

[0034] 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.

[0035] In one embodiment, that is, in step S33, the major transient of the unit includes reactor power change, pressure change, flow change and temperature change, that is, when the risk type is a major transient of the unit, determining that the target response organization is the second target response organization includes the following steps: 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 rate is greater than the first preset flow rate or less than the second preset flow rate 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, determine that the target response organization is the second target response organization.

[0036] 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 as to take appropriate measures to deal with possible problems, and the response efficiency of the target response organization is also improved.

[0037] For example, the following conditions are set: During the first preset time: the first preset power is P1, and the second preset power is P2; During the second preset time: the first preset pressure is P1 压 , the second preset pressure is P2 压 ; During the third preset time: the first preset flow rate is Q1, and the second preset flow rate is Q2; In the fourth preset time: the first preset temperature is T1, and the second preset temperature is T2.

[0038] Now, if one of the following happens: The reactor power is greater than the first preset power within the first preset time (P>P1); The reactor power is less than the second preset power (P <P2); The pressure is greater than the first preset pressure (P 压 >P1 压 ); The pressure is less than the second preset pressure (P 压 <P2 压 ); The flow rate is greater than the first preset flow rate within the third preset time (Q>Q1); The flow rate is less than the second preset flow rate (Q <Q2); The temperature is greater than the first preset temperature within a fourth preset time (T>T1); The temperature is lower than the second preset temperature (T <T2); Then, the target response organization will be determined as the second target response organization.

[0039] It should be noted that the first preset time, the second preset time, the third preset time, and the fourth preset time may be the same or different, and the specific present invention does not limit them. For example, the first preset time may be 1 minute, 5 minutes, 10 minutes, or other time and time period, and so on. In order to avoid repetition, the present invention will not repeat them. Similarly, other preset conditions may also be set according to actual conditions, and the present invention will not repeat them one by one.

[0040] 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: S41, inputting the fault analysis result into a risk prediction model to obtain a risk prediction result output by the risk prediction model, wherein the risk prediction model is trained based on historical data of the fault analysis result.

[0041] 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 predict and evaluate the risks that will occur in the future. 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 results may include but are not limited to information such as risk level, probability of future faults, and suggestions on whether to adjust the current target response organization. This information can help the 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 the above manner, the tediousness of the traditional meeting to discuss whether to adjust the response organization can be saved, and it can be more accurately determined whether to adjust the target response organization and improve efficiency.

[0042] In one embodiment, the risk prediction model can be trained in the following way: Obtain historical data from fault analysis results, including the type of fault, specific cause, fault mode and impact scope, and other relevant information; 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 abnormal values, and performing data conversion and standardization; The prediction model is trained according to 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.

[0043] Exemplarily, past fault data are obtained from the operation records and fault database of the nuclear power plant, including information such as fault type (such as pipeline leakage, control system failure), specific causes (such as equipment aging, operational errors), fault mode and scope of impact. Then, the acquired fault data is preprocessed, including removing duplicate data, processing missing values ​​(such as filling with interpolation), processing outliers (such as smoothing or deleting abnormal data points), performing data conversion (such as feature extraction of time series data) and standardization (such as scaling data to a similar range). Then, the preprocessed data is divided into a training set and a validation set, and then the data is trained using appropriate machine learning algorithms (such as support vector machines, random forests), the model parameters are adjusted to improve the prediction accuracy, and the model performance (such as accuracy, recall rate) is evaluated. Through the above process, a risk prediction model for abnormal nuclear power units can be established to determine in advance whether to switch the target response organization to ensure the safe and stable operation of the nuclear power plant.

[0044] It should be noted that the above is only an example and the present invention is not limited thereto.

[0045] 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.

[0046] In one embodiment, the risk prediction result is sent to the risk result output page in some way (for example, network transmission, database update or other forms). This page is an interface for displaying the results of risk prediction so that the target user can intuitively understand the current risk status and suggestions. Among them, the target users include multiple, for example, the duty supervisor, safety supervisor, engineer, first and second target response organization leaders and deputy leaders, etc., through viewing the risk prediction results on this risk result output page. According to this risk prediction result, they can perform corresponding control operations on the page according to their respective professional knowledge and responsibilities. This control operation can be to agree to adjust the current target response organization or disagree to adjust the current target response organization. When the target user completes the control operation, the nuclear power unit abnormal response system will generate target instructions based on these operations, and these target instructions represent whether to agree to adjust the current target response organization. In this way, the risk prediction results can not only be communicated to multiple target users in a timely and accurate manner, but also can be converted into specific response measures through their operations, thereby ensuring the safe operation of nuclear power plants or related facilities, avoiding the traditional problem of slow processing efficiency caused by holding meetings, and ensuring the synergy and efficiency of risk management and emergency response.

[0047] S43: After receiving target instructions corresponding to multiple target users, obtain weight values ​​corresponding to the target users.

[0048] 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 general 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 safety supervisor, the first and second target response organization leaders and deputy leaders may be relatively low, which may 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 it can be set specifically according to actual conditions, and the present invention does not limit it.

[0049] 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.

[0050] In one embodiment, multiple target users may include target users A, B, C, D, and E, and 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. Among them, the first target instruction may be a representation of agreeing to adjust the current target response organization, and the second target instruction may be a representation of disagreeing to adjust the current target response organization; and 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, and the specific present invention is not limited. Then, according to 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 and compared to determine whether to adjust the current target response organization. Through the above judgment, the accuracy and efficiency of the decision are ensured. At the same time, this method also reflects the advantages of collaborative decision-making, which can better play the professional advantages of each target user and improve the overall ability to deal with risks. It should be noted that the above is only an example and the present invention is not limited thereto.

[0051] 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 plurality of target users and the weight values ​​corresponding to the target users, includes the following steps: S441. When the target instruction is a first target instruction, obtain weight values ​​of all the first target instructions corresponding to the target users; S442: Calculate a first calculation result based on the weight values ​​of all target users corresponding to the first target instructions; S443: when the target instruction is a second target instruction, obtaining weight values ​​of all the second target instructions corresponding to the target users; S444. Calculate a second calculation result based on the weight values ​​of all target users corresponding to the second target instructions; S445. Determine whether to adjust the current target response organization according to the magnitudes of the first calculation result and the second calculation result.

[0052] Specifically, first, the abnormal response system of the nuclear power unit will check whether the current target instruction is the first target instruction or the second target instruction; if it is the first target instruction, the abnormal response system of the nuclear power unit will obtain the weight values ​​of all target users related to it, and calculate based on these weight values ​​to obtain the first calculation result. If it is the second target instruction, the abnormal response system of the nuclear power unit will obtain the weight values ​​of all target users related to it, and calculate based on these weight values ​​to obtain the second calculation result. Finally, the abnormal response system of the nuclear power unit will compare the size of the first calculation result and the second calculation result to determine whether the current target response organization needs to be adjusted. If the first calculation result is larger, it indicates that the current target response organization is adjusted. On the contrary, if the second calculation result is larger, it indicates that the current target response organization is not 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 according to different target instructions and the weight values ​​of related users, as well as the comparison of calculation results, so as to better handle the abnormal situation of the current nuclear power unit.

[0053] Exemplarily, assuming 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.

[0054] When OI_1 is the first target instruction: Get the weight value of all OI1 corresponding to the target user: W1 Calculate the first calculation result:

[0055] When OI2 is the second target instruction: Get the weight value of all OI2 corresponding to the target user: W2 Calculate the second calculation result:

[0056] For example, for OI1: The weight value of target user A is 0.3 The target user B has a weight of 0.5 The target user C weight value is 0.3 Then W1 = [0.3, 0.5, 0.3] For OI2: The target user D weight value is 0.4 The target user E weight value is 0.4 The target user F weight value is 0.2 Then W2 = [0.4, 0.4, 0.2] For OI1: The first calculation result is CR1 = 0.3 + 0.5 + 0.3 = 1.1 For OI2: The second calculation result is CR2 = 0.4 + 0.4 + 0.2 = 1.0 It is obtained 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 also the basis for decision-making can 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 the specific present invention is not limited thereto.

[0057] In one embodiment, step S445, that is, determining whether to adjust the current target response organization according to the magnitude of the first calculation result and the second calculation result, includes the following steps: S4451: When the target response organization is the first target response organization and the first calculation result is greater than the second calculation result, adjusting the first target response organization to the second target response organization; 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.

[0058] 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 unit abnormal response system will perform an adjustment of 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 unit abnormal response system will maintain the target response organization as the first target response organization.

[0059] It should be noted that the target response organization may also include a third target response organization, and the third target response organization may respond when an accident or natural disaster occurs. 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. In addition, modulation may also be directly performed from the first target response organization to the third target response organization, and the specific present invention is not limited thereto.

[0060] In one embodiment, that is, in step S40, after receiving the fault analysis result, the following steps are further included: S45, determining a fault mode according to the fault analysis result; S46: Determine whether to start an emergency repair team according to the fault mode.

[0061] In one embodiment, the fault mode is determined according to the fault analysis result, and the fault mode includes but is not limited to hardware fault: including hardware faults caused by circuit component damage, connection problems, equipment aging, etc.; software fault: including software faults caused by program errors, logical errors, memory overflow, etc.; communication fault: including communication faults caused by network connection problems, communication protocol errors, signal interference, etc.; power supply fault: including power supply faults caused by unstable voltage, power interruption, power overload, etc.; environmental fault: including faults caused by environmental factors such as excessive temperature, excessive humidity, and dust accumulation; human operation error: including faults caused by human factors such as misoperation, improper operation, and improper maintenance. After determining the fault mode, the impact and urgency of the fault on the system are evaluated to determine whether it is necessary to start the emergency repair group. For example, when a human operation error or environmental fault occurs, the emergency repair group is not started; when a software fault, hardware fault or power fault occurs, the emergency repair group is started. Through the above judgment, the waste of personnel is reduced, unnecessary emergency repair actions are avoided, and the efficiency of resource utilization is improved. The corresponding emergency repair team is only activated 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.
