Description
Operating Technology Guidelines Operating Restriction Conditions Monitoring Platform System
[0001] The present invention relates to an operating technology manual operation limitation condition monitoring platform system, and relates to an operating technology manual operation limitation condition monitoring platform system for efficient operation according to various operating modes of a power plant.
[0002] In nuclear power plants, the safe operation of the power plant is ensured by complying with the operating restrictions in the operating technical manual.
[0003] However, the number of driving restriction conditions that must be monitored is large and the situations in which the driving restriction conditions must be applied are very diverse, making it difficult for drivers to monitor the driving restriction conditions.
[0004] In addition, even if the driver detects a situation that exceeds the limit, the driving restriction conditions are qualitatively described, requiring additional judgment from the driver to determine satisfaction / dissatisfaction, which delays judgment and continues to result in violations of the driving restriction conditions.
[0005] Previously, according to Korean Patent No. 2274139, monitoring was performed simply using power plant operation modes types 1 to 6, so frequent false alarms are expected, and monitoring of operating restriction conditions for power plant situations in No mode is impossible.
[0006] Furthermore, the lack of supporting information to determine actual satisfaction / dissatisfaction necessitates additional judgment from the driver, limiting the time available for taking action when dissatisfied. Furthermore, there is no way to prevent violations due to non-application or misapplication.
[0007] Accordingly, there is a problem that cases of violations of non-application of operating restriction conditions continue to occur due to the absence of a system that can detect situations exceeding the operating restriction conditions considering the various operating modes of the power plant, and cases of violations of non-application or incorrect application of operating restriction conditions continue to occur due to the absence of a system to determine satisfaction / dissatisfaction of the operating restriction conditions that are qualitatively described.

[0009] [Patent Document]
[0010] (Patent Document 1) Korean Patent No. 2274139 (July 1, 2021)
[0011] The present invention is intended to solve the above-described problem, and provides an operating technology guideline operating restriction condition monitoring platform system capable of determining power plant operating modes 1 to 6, as well as No mode and detailed operating mode for each operating mode.
[0012] In addition, the purpose is to provide an operating technology guideline operating restriction condition monitoring platform system that can accurately determine the operating mode to which the operating restriction conditions should be applied and detect situations exceeding the operating restriction conditions.
[0013] The purpose is to provide an operating technology guideline operating restriction condition monitoring platform system that enables the driver to determine whether the operating restriction condition is satisfied or not after detecting an abnormal situation.
[0014] The present invention includes an operation mode determination unit (110) that determines a detailed operation mode for each operation mode based on real-time measurement variables of a power plant and calculation information on the number of operators, an abnormality detection unit (120) that monitors the measurement variables of the power plant and detects a situation that deviates from the set operation restriction conditions, and an operator notification support unit (130) that provides a notification to the operator when the measurement variables of the power plant are changed and supports the decision-making on whether the operation restriction conditions are satisfied or not, while allowing the operation mode to be changed manually or automatically according to the set conditions.
[0015] The driving mode determination unit (110) includes a data collection module (111) that collects data by receiving real-time measurement variables and calculation information on the number of operators, a condition evaluation module (112) that defines conditions corresponding to each driving mode in advance and evaluates whether the currently input data meets the conditions through the data collection module, and a driving mode determination module (113) that determines the current driving mode based on the evaluation result of the condition evaluation module and determines the detailed driving mode for each driving mode based on the detailed operating conditions of the power plant.
[0016] The driver notification support unit (130) provides support information for decision-making on satisfaction / dissatisfaction with driving restriction conditions to the driver terminal in real time, and provides information analyzed through preset conditions according to the analysis tool of a pre-driving expert to the driver terminal, and manages the application history of driving restriction conditions based on whether the data input from the driver terminal matches the analysis result of the analysis tool.
[0017] According to the present invention, in addition to power plant operation modes 1 to 6, the No mode and detailed operation modes for each operation mode can be determined, and the operation mode to which operation restriction conditions should be applied can be accurately calculated, thereby having the effect of detecting situations exceeding operation restriction conditions.
[0018] Figure 1 is a configuration diagram of an operating technology guideline operation restriction condition monitoring platform system according to one embodiment of the present invention.
[0019] Figure 2 is a detailed configuration diagram of an operation mode determination unit of an operation technology guideline operation restriction condition monitoring platform system according to one embodiment of the present invention.
[0020] The operating technology guideline operating restriction condition monitoring platform system according to one embodiment of the present invention can determine power plant operating modes 1 to 6, as well as No mode and detailed operating modes for each operating mode.
[0021] In addition, it accurately calculates the driving mode to which the driving restriction conditions should be applied, enabling detection of situations exceeding the driving restriction conditions.
[0022] And after detecting an abnormal situation, it is possible to determine whether the driver's driving restrictions are satisfied or not.
[0023] Using the real-time measurement variables of the power plant and the calculation information of the number of operators, various power plant operation modes 1, 2, 3, 4, 5, 6, and No Mode are calculated in real time, and when the conditions are met, when condition 1) the output is increased, the operation mode is changed by providing a notification to the operator, and when condition 2) the output is decreased or tripped, the operation mode is immediately changed. At this time, the operation mode is finally changed through the operator's user terminal confirmation.
[0024] Monitoring of the operating constraints of each power plant can be done in real time, and in some cases, real-time measurement is not possible. In cases where real-time measurement is not possible, the operator performs a regular inspection and enters the results into the system, which automatically calculates the value and applies a mixed automatic and manual monitoring method.
[0025] It provides real-time support information to the driver for decision-making on whether to satisfy or dissatisfy driving constraints. Information analyzed through a pre-driving expert analysis tool is provided to the driver, and the driver then makes a decision by comprehensively judging the power plant information.
[0026] Condition 1) If the analysis result of the pre-driving expert analysis tool matches, the application history of the driving restriction condition is managed.
[0027] Condition 2) If there is a discrepancy between the analysis results of the pre-driving expert analysis tool and the previous driver's analysis results, the analysis results of the pre-driving expert analysis tool and the previous driver's analysis results are automatically included and displayed together at the time of the next decision.
[0028] Hereinafter, the present invention will be described in more detail with reference to the attached drawings.
[0029] Figure 1 is a configuration diagram of an operating technology guideline operation restriction condition monitoring platform system according to one embodiment of the present invention.
[0030] As illustrated in Fig. 1, the operating technology instruction manual operating restriction condition monitoring platform system (10) includes an operating mode determination unit (110), an abnormal situation detection unit (120), and an operator notification support unit (130).
[0031] The driving mode determination unit (110) is configured to determine the driving mode using the real-time measurement variables of the power plant and the number of operators calculated information.
[0032] In this embodiment, the variables that determine the power plant operation mode are the reactivity condition, the rated thermal output, and the reactor coolant low-temperature tube temperature.
[0033] For reference, the operator count information entered through the operator terminal refers to additional information entered or confirmed through the operator's user terminal, separate from the power plant's real-time measurement variables. For example, this may include variables that are difficult to automatically measure in real time or the results of periodic inspections.
[0034] Driver counting information includes data directly entered or confirmed through the driver's user terminal. This information may primarily include the following elements:
[0035] Driver count information includes regular inspection results that check the status of specific equipment or systems, variables that are difficult to automatically measure in real time, manual input data directly entered by drivers in emergency situations, and logs (event logs) recorded by drivers when specific events or abnormal situations occur.
[0036] The driving mode determination of the driving mode determination unit (110) according to this embodiment is described as follows.
[0037] In the process of collecting real-time measurement variables, real-time measurement variables are crucial for understanding the current status of a power plant. However, for variables that are difficult to automatically measure in real time or for periodic inspection results, operator-calculated information is required.
[0038] Accordingly, the operation mode determination unit (110) according to the present embodiment determines the operation mode (power plant operation modes 1 to 6, as well as No mode) using the real-time measurement variables of the power plant and the calculation information of the number of operators, and can determine the detailed operation mode for each operation mode.
[0039] For reference, the detailed driving mode for each driving mode determines whether the output is increased or decreased or in the event of a trip. That is, when condition 1) the output is increased, a notification is provided to the driver to change the driving mode, and when condition 2) the output is decreased or in the event of a trip, the driving mode is immediately changed.
[0040] Figure 2 is a detailed configuration diagram of an operation mode determination unit of an operation technology guideline operation restriction condition monitoring platform system according to one embodiment of the present invention.
[0041] This driving mode determination unit (110) includes a data collection module (111), a condition evaluation module (112), and a driving mode determination module (113) to determine the driving mode based on the real-time measurement variables of the power plant and the number of operators calculated.
[0042] The data collection module (111) collects data by receiving real-time measurement variables and driver number calculation information.
[0043] The condition evaluation module (112) defines conditions corresponding to each driving mode in advance and evaluates whether the currently input data meets these conditions through the data collection module.
[0044] The conditions corresponding to each driving mode defined in advance in the condition evaluation module (112) are as follows.
[0045] Operation mode 1 is when the reactivity condition is 0.99 or higher, the rated heat output exceeds 5%, and there is no reactor coolant.
[0046] Operation mode 2 is when the reactivity condition is 0.99 or higher, the rated heat output is less than 5%, and there is no reactor coolant.
[0047] Operation mode 3 is when the reactivity condition is less than 0.99, the rated heat output is not applicable, and the reactor coolant temperature is 177 degrees or higher.
[0048] Driving mode 4 is when the reactivity condition is less than 0.99, the rated heat output is not applicable, the reactor coolant exceeds 99, and the temperature is less than 177 degrees.
[0049] Operation mode 5 is when the reactivity condition is less than 0.99, the rated heat output is not applicable, and the reactor coolant is 99 or less.
[0050] Driving mode 6 is when one or more of the upper head studs of the reactor vessel are not engaged.
[0051] No Mode is when there is no nuclear fuel inside the reactor vessel.
[0052] The driving mode determination module (113) determines the current driving mode based on the evaluation result of the condition evaluation module and determines the detailed driving mode for each driving mode.
[0053] Accordingly, the operation mode determination module (113) determines, for example, the current operation mode of the power plant as operation mode 2. Through this process, the real-time measurement variables of the power plant and the calculation information of the number of operators can be comprehensively analyzed, and the operation mode can be accurately determined based on the evaluation results of the condition evaluation module.
[0054] In addition, the operation mode determination unit (110) according to the present embodiment determines the operation mode (power plant operation modes 1 to 6, as well as No mode) using the real-time measurement variables of the power plant and the calculation information of the number of operators, and can determine the detailed operation mode for each operation mode. Here, the detailed operation mode means when the output is increased, when the output is reduced, or when there is a trip (emergency stop) situation.
[0055] Regarding the detailed operating mode determination criteria, Condition 1) When increasing output, the operating mode determination unit detects the increased power plant output through real-time measurement variables. In this case, it notifies the operator, prompting them to manually change the operating mode. This process is followed by a final operating mode change upon operator confirmation.
[0056] Condition 2) If output decreases or a trip (emergency stop) occurs, the driving mode determination unit immediately detects this and automatically changes the driving mode. In this case, the system immediately changes the driving mode without operator intervention.
[0057] The driving mode determination process is explained with an example as follows.
[0058] When the output increases, the data collection module (111) receives real-time measurement variables and driver number calculation information and collects data.
[0059] The condition evaluation module (112) evaluates whether the currently input data satisfies the conditions of each operation mode. For example, if the reactivity condition is 0.99 or higher and the rated heat output exceeds 5%, the conditions of operation mode 1 are satisfied.
[0060] The driving mode determination module (113) detects a situation where output is increasing. Based on condition 1, the driver notification support unit (130) provides a notification to the driver terminal to change the driving mode. The driving mode is finally changed after the driver confirms it.
[0061] In the event of a power reduction or trip situation, the data collection module (111) receives real-time measurement variables and driver counting information and collects data.
[0062] The condition evaluation module (112) evaluates whether the currently input data satisfies the conditions of each operation mode. For example, if the reactivity condition is less than 0.99 and the reactor coolant low-temperature tube temperature is 177 degrees or higher, the condition of operation mode 3 is satisfied.
[0063] The driving mode determination module (113) detects a reduced output or a trip situation. Accordingly, the driving mode is automatically and immediately changed through the driver notification support unit (130) according to condition 2.
[0064] That is, when a decrease in output or a trip situation is detected, the driving mode determination module (113) reevaluates the current driving mode and automatically sets an appropriate new driving mode through the driver notification support unit (130). For example, if the current driving mode is 1, if the output is significantly reduced, it can be changed to driving mode 3, 4, 5, etc., and in the case of a trip situation, it can be immediately changed to driving mode 6.
[0065] Once the automatic operation mode change is complete, the operation mode determination module sets a detailed operation mode within the new operation mode. For example, if a power reduction is detected and the operation mode changes to 4, an appropriate detailed operation mode, such as "Power Adjustment" or "Maintenance Preparation," is set within this operation mode. In a trip situation, the detailed operation mode is set to "Emergency."
[0066] After the driving mode is automatically changed, the driver notification support unit (130) provides the driver terminal with a notification regarding the changed driving mode and detailed driving mode. This allows the driver to immediately recognize the current situation and take necessary actions.
[0067] For example, in the case of a trip (emergency stop), if the current driving mode is 2 and an emergency stop signal is generated, the data acquisition module detects the emergency stop signal, the condition evaluation module evaluates the trip situation, and the driving mode determination module automatically sets the new driving mode to 6. The detailed driving mode is set to "emergency situation," and the driver notification support unit notifies the driver of the changed driving mode.
[0068] In this way, in the event of a power reduction or trip situation, the operation mode determination unit can perform an immediate operation mode change based on real-time data to ensure the safety and efficient operation of the power plant.
[0069] For reference, the driving mode determination unit (110) according to this embodiment determines the driving mode (driving mode 1 to 6 and No Mode) using the real-time measurement variables of the power plant and the number of operators calculation information, and determines the detailed driving mode for each driving mode.
[0070] The data collection module (111) continuously receives real-time measurement variables of the power plant and calculation information on the number of operators to collect data.
[0071] Real-time measurement variables include various variables such as reactivity conditions, rated thermal power, and reactor coolant cryogenic tube temperature. Operator count information includes operational data such as the number of currently operating operators.
[0072] The condition evaluation module (112) has conditions corresponding to each predefined operation mode. It evaluates whether real-time data collected through the data collection module meets these conditions. The conditions for each operation mode are as follows. Operation mode 1 is a reactivity condition of 0.99 or higher, a rated thermal output exceeding 5%, and no reactor coolant. Operation mode 2 is a reactivity condition of 0.99 or higher, a rated thermal output less than 5%, and no reactor coolant. Operation mode 3 is a reactivity condition of less than 0.99, a rated thermal output not applicable, and a reactor coolant temperature of 177°C or higher. Operation mode 4 is a reactivity condition of less than 0.99, a rated thermal output not applicable, and a reactor coolant temperature of more than 99°C and less than 177°C. Operation mode 5 is a reactivity condition of less than 0.99, a rated thermal output not applicable, and a reactor coolant temperature of 99°C or lower. Operation mode 6 is a failure to fasten at least one of the upper head studs of the reactor vessel. No mode means that there is no nuclear fuel in the reactor vessel.
[0073] The operation mode determination module (113) determines the current operation mode of the power plant based on the evaluation results of the condition evaluation module. For example, if the reactivity condition is 0.99 or higher and the rated thermal output exceeds 5% as a result of evaluating real-time measurement variables, operation mode 1 is determined.
[0074] In determining the detailed operation mode, the detailed operation mode is determined based on the situation within each operation mode. Condition 1: In situations where output increases, the driver is notified and asked to manually change the operation mode. The operation mode is finally changed upon the driver's confirmation. Condition 2: In situations where output decreases or a trip (emergency stop) occurs, the system immediately detects this and automatically changes the operation mode. The system immediately changes the operation mode without operator intervention. For example, if output increases, the detailed operation mode is set to "Increasing Output," if output decreases, "Decreasing Output," and if a trip occurs, "Emergency."
[0075] When the driving mode changes, the driver notification support unit (130) provides the driver terminal with a notification of the changed driving mode and detailed driving mode. This allows the driver to immediately recognize the current situation and take necessary actions.
[0076] The abnormal situation detection unit (120) monitors the measurement variables of the power plant for each operation mode and detects situations that exceed the set operation restriction conditions.
[0077] The abnormal situation detection unit according to this embodiment is configured to detect an abnormal situation in the operating restriction conditions, and the function of monitoring the measurement variables of the power plant for each operating mode and detecting the set operating restriction conditions enables rapid recognition and response to the abnormal situation.
[0078] These abnormal situations refer to situations that exceed the operating restrictions set in the power plant's operating technical instructions.
[0079] The abnormal situation detection unit (120) monitors in real time the operating restriction conditions set according to the power plant's operating technology guidelines.
[0080] This abnormal situation detection unit (120) continuously monitors important operating parameters such as reactor coolant temperature, pressure, and flow rate to determine whether any operating constraints are violated. If an abnormality is detected, an alarm is immediately generated.
[0081] For example, if the reactor coolant temperature is to be maintained between 280°C and 320°C, the monitoring unit continuously monitors this. If the temperature rises to 325°C, it is detected and an alarm is immediately generated.
[0082] For reference, the Operational Limiting Conditions (OLC) established in accordance with the operating technical guidelines of a power plant refer to the limit values of specific operating parameters that must be observed to ensure the safety and stable operation of the power plant.
[0083] Operating constraints are established to ensure the normal operation of various devices and systems and maintain a safe operating environment. Specific operating constraints may vary depending on the type and design of the power plant, but typically include the following elements:
[0084] The reactor coolant temperature must remain within a certain range for the safe operation of the reactor. For example, the reactor coolant temperature must be maintained between 280°C and 320°C.
[0085] The pressure inside the reactor must remain within certain limits for safe operation. For example, the pressure inside the reactor must be maintained between 1,500 and 2,500 psi.
[0086] The coolant flow rate must be above a certain level to ensure sufficient cooling. For example, the coolant flow rate should be at least 5,000 liters / minute.
[0087] The temperature of the reactor fuel must be maintained within safe limits. For example, the fuel temperature must not exceed 1000 degrees Celsius.
[0088] Radiation levels inside and outside the reactor must not exceed acceptable levels, not exceeding 5 millisieverts (mSv) per hour.
[0089] Regarding the operating status of the cooling system, the operating status of the cooling pump, heat exchanger, etc. must be normal, and the operating pressure and flow rate of the pump must be within the specified range.
[0090] At this time, with regard to the operating status of the cooling system, the operating status of the cooling pump and heat exchanger, etc. must be normal, which means that the performance of the cooling system must be maintained stably and efficiently.
[0091] The specific values may vary depending on the design and operating manual of the power plant, but for example, the pressure of the cooling pumps represents the condition that the cooling water must be circulated at an appropriate pressure, which is between 1500 psi (pounds per square inch) and 2500 psi. If the pressure is too low, the cooling water may not be circulated sufficiently, which may prevent proper reactor cooling, and if the pressure is too high, the system may be overloaded and may be damaged.
[0092] The flow rate of a cooling pump refers to the amount of coolant the pump circulates over a given period of time. This directly affects the heat removal efficiency of the cooling system. If the flow rate exceeds the specified range, the reactor's heat may not be sufficiently removed.
[0093] For example, a flow rate between 5,000 and 10,000 liters / min represents sufficient cooling water circulation to effectively remove heat from the reactor. Too low a flow rate could insufficiently cool the reactor, potentially causing the reactor temperature to rise. Too high a flow rate could overload the system, reducing efficiency.
[0094] To give a specific example of operation, the monitoring unit can be considered to be operating stably as the measured value of the pump operating pressure is within the normal range of 1500 psi to 2500 psi while operating at a pressure of 2000 psi.
[0095] If the pump flow rate is within the normal range of 5,000 liters / minute to 10,000 liters / minute, assuming that the pump is circulating the cooling water at a flow rate of 7,000 liters / minute, the cooling system can be considered to be operating efficiently since the pump flow rate is within the normal range.
[0096] Regarding safety system operation, systems for safely shutting down the reactor in an emergency must function normally. Emergency cooling systems, radiation shielding systems, and other systems must function normally, and their operating conditions must remain within specified limits.
[0097] The Emergency Core Cooling System (ECCS) is designed to prevent reactor overheating and minimize fuel damage. The ECCS must have a flow rate of at least 10,000 liters / minute. The ECCS pressure must be between 1,500 and 2,500 psi, and the coolant temperature must be between 50 and 150°C.
[0098] Radiation shielding systems are designed to maintain radiation levels within and around power plants at safe levels. Radiation levels must not exceed 5 millisieverts (mSv) per hour, and the materials used for radiation shielding must be in good condition. The thickness, density, and other characteristics of the shielding materials must meet established standards.
[0099] Simultaneously monitor the operating conditions of the safety system's emergency cooling system and radiation shielding system, so that an alarm can be generated if they exceed the specified range.
[0100] Regarding chemical concentrations, the chemical composition of coolants and other operating materials must be maintained within specified concentrations. The boron concentration in coolants must be maintained between 1,000 and 2,000 ppm.
[0101] The driver notification support unit (130) provides a notification to the driver when the measured variables of the power plant change according to the driving mode and supports decision-making based on whether the driving restriction conditions are satisfied or not, but changes the driving mode manually or automatically according to the set conditions.
[0102] In the driver notification support unit (130) according to the present embodiment, the final change in driving mode is made through confirmation of the driver's decision based on whether the driver's driving restriction conditions are satisfied or not. At this time, various power plant driving modes 1, 2, 3, 4, 5, 6, and No Mode are calculated in real time using the real-time measurement variables of the power plant and the number of drivers input through the driver terminal, and the driving mode is changed when the corresponding conditions are met.
[0103] For example, Condition 1 of the Driver Notification Support Unit provides a notification to the driver terminal when power output increases, prompting the driver to manually change the driving mode. The final change in driving mode is confirmed by the driver. Condition 2 of the Driver Notification Support Unit automatically and immediately changes the driving mode when power output decreases or a trip (emergency stop) occurs.
[0104] This driver notification support unit (130) provides a notification to the driver terminal when the power plant's measurement variables change after detecting an abnormal situation so that the driver can determine whether the driving restriction conditions are satisfied or not, and supports the decision-making process of whether the driving restriction conditions are satisfied or not, and the function of supporting manual or automatic changing of the driving mode according to preset conditions helps the driver make quick and accurate decisions and allows immediate action to be taken when necessary.
[0105] Here, the preset conditions for supporting changing the driving mode to manual or automatic are described as follows.
[0106] The driver notification support unit (130) according to this embodiment provides the driver with real-time support information for making decisions regarding whether or not the driving constraints are satisfied. The information analyzed through pre-determined conditions based on an analysis tool from a pre-driving expert is then provided to the driver, who then comprehensively assesses the power plant's information to make a decision. This decision-making process is intended to determine whether the driver should change to the optimal driving mode that satisfies the driving constraints based on the current situation. This includes whether to change the driving mode manually or automatically.
[0107] For example, an example of changing the driving mode according to preset conditions is as follows.
[0108] If the current situation corresponds to driving mode 2, and the driver's analysis results determine that the current condition satisfies the driving restriction conditions, and the pre-driving expert analysis tool analyzes that the current condition satisfies the driving restriction conditions, that is, if the driver's analysis results and the pre-driving expert analysis tool results match, then the application history of the driving restriction conditions is recorded, the driver is informed of this, and the current mode is maintained.
[0109] At this time, the driver notification support unit (130) generates a notification that the current driving restriction conditions are met and that the driving mode should be maintained. During the decision-making process, the driver confirms the notification from the operating technical manual's driving restriction condition monitoring platform system and maintains the current status without taking any additional action.
[0110] In addition, if the current situation corresponds to driving mode 1, if the pre-driving expert analysis tool analyzes that the current condition satisfies the driving restriction conditions, and the driver analysis results determine that the current condition does not satisfy the driving restriction conditions, that is, if the driver's analysis results and the pre-driving expert analysis tool results do not match, the driver notification support unit of the operating technology manual driving restriction condition monitoring platform system additionally records the driver's analysis results in the pre-driving expert analysis tool analysis results, and displays them together on the driver terminal when making the next decision.
[0111] For example, a notification is sent to the driver's terminal indicating that the current driving restrictions are unsatisfactory, the expert analysis tool indicates satisfaction, but further analysis is required for the next decision. The driver then checks the notification on their terminal and, based on the results of the pre-driving expert analysis tool, decides whether to maintain or change the current mode.
[0112] For reference, the pre-operation expert's analysis tool analyzes and predicts operational constraints based on power plant operating conditions, past data, and simulation results. This tool comprehensively analyzes power plant operational data to detect abnormal situations and, based on these findings, proposes measures or operating mode changes to meet operational constraints.
[0113] In the driver notification support unit (130), the first condition set in advance of the pre-driving expert analysis tool is such that when the analysis result of the driver input through the driver terminal matches the analysis result of the pre-driving expert analysis tool, the application history of the corresponding driving restriction condition is managed.
[0114] In addition, the second preset condition is that if the analysis result of the operator input through the operator terminal and the analysis result of the pre-operation expert analysis tool do not match, the analysis result of the operator is additionally included in the analysis result of the pre-operation expert analysis tool and the results are shown together at the next decision-making stage, so that decisions can be made by comprehensively judging the information of the power plant.
[0115] Here, the decision-making process automatically changes the driving mode when the analysis results of a predefined pre-drive expert analysis tool match the driver's judgment criteria. For example, if power output suddenly decreases, the driving mode is automatically re-evaluated and changed.
[0116] Additionally, when there is a discrepancy between the analysis results of the predefined pre-driving expert analysis tool and the driver's judgment criteria, the driver reviews the notification through the terminal and decides whether to manually change the driving mode.
[0117] According to the present invention, in addition to power plant operation modes 1 to 6, the No mode and detailed operation modes for each operation mode can be determined, and the operation mode to which operation restriction conditions should be applied can be accurately calculated, thereby having the effect of detecting situations exceeding operation restriction conditions.
