The accident situation implementation unit 200 is a component that acquires scenario data from the scenario database 110 and implements a situation in which an accident occurs in a virtual power plant based on the scenario data. For example, the accident situation implementation unit 200 models a virtual power plant, a virtual device, and an accident situation based on the scenario data, and displays the modeled virtual power plant, the virtual device, and the accident situation on the screen, according to the operator's input. It may be a simulator that changes an image displayed on the screen or changes an image reproduced on the screen according to a driver's input.

Specifically, the accident situation implementation unit 200 is a component that provides a virtual reality or augmented reality environment so that an operator can perform a simulation of manually taking a specific virtual device corresponding to a specific device in the virtual power plant. To this end, the accident situation realizing unit 200 provides a virtual power plant, a virtual device, and provides a visualization, and changes the visualized image by receiving the operator's input.

The process is called the action process.

Referring to FIG. 1 , the accident situation realizing unit 200 may include a modeling unit 210 , a display unit 240 , an input unit 220 , and a control unit 230 .

The modeling unit 210 is a component that models a virtual power plant corresponding to the power plant and a plurality of virtual devices corresponding to a plurality of devices installed in the power plant, and implements an accident situation in the modeled virtual power plant. Specifically, the modeling unit 210 models and implements a situation in which an accident has occurred in the virtual power plant based on modeling information on the power plant included in the scenario data, modeling information on a plurality of devices, and modeling information on the accident.

Here, the virtual power plant is modeled based on the modeling information of the power plant included in the scenario data, and may be modeled identically or similarly to the real power plant. In addition, the plurality of virtual devices may be modeled based on modeling information about the plurality of devices, and may be modeled identically or similarly to an actual power plant.

Meanwhile, the modeling unit 210 may be provided to implement a situation in which an accident has occurred in the virtual power plant based on modeling information about the accident included in the scenario data. For example, the modeling unit 210 analyzes the accident situation in the virtual power plant based on information about the type of accident (tsunami, earthquake, fire, malfunction of equipment, etc.), the system in which the accident occurred, the location where the accident occurred, etc. It can be modeled and implemented.

For example, the modeling unit 210 may model a situation in which a fire occurs in a specific area of a power plant and a manual action of an operator is required for a specific device based on the scenario data. In this case, the modeling unit 210 models a virtual power plant based on the scenario data and implements or models a situation in which a fire occurs in the virtual power plant. For example, the modeling unit 210 implements or models the movement of fire over time and a process in which a plurality of devices installed in a fire zone are affected by the fire.

The display unit 240 is a component that visualizes the virtual power plant modeled by the modeling unit 210 under the control of the control unit 230 , a plurality of virtual devices, and the accident situation on the screen.

For example, the display unit 240 may include a display (not shown) having a screen that displays the virtual power plant modeled by the modeling unit 210 on a two-dimensional screen.

Or, for example, the display unit 240 may be provided to provide an augmented reality service to the participating driver.

It may include an overlap display unit (not shown) overlapping the , and a display (not shown) for displaying the overlapped image on the screen.

The input unit 220 is a component operated by the participating operator to start and proceed the simulation. Specifically, the input unit 220 may be a component that provides an input for the participating driver to interact with the virtual space modeled by the modeling unit 210 .

For example, the input unit 220 may include a user interface displayed on the display unit 240 or a graphic user interface. In addition, the input unit 220 may include a keyboard, a mouse, or a corresponding input means. In addition, the input unit 220 may include a separate input device recognized by the image acquisition unit so that a simulation service based on augmented reality is provided to the participating driver.

Meanwhile, the input unit 220 may include a walking unit (not shown) in which the participating driver walks. The walking unit may be configured to allow the driver to ride and walk. Specifically, the walking unit is provided to measure the walking speed of the driver. For example, the walking unit may include a conveyor having a belt on which an operator walks. For example, the walking unit may be configured the same as or similar to a treadmill.

The controller 230 controls the modeling unit 210 and/or the display unit 240 according to an input of the input unit 220 . Specifically, the controller 230 may control the modeling unit 210 and the display unit 240 so that the simulation proceeds according to the input of the input unit 220 .

The control unit 230 controls the modeling unit 210 when the participating operator inputs an input for selecting an accident to model the virtual power plant, the virtual device, and the accident situation. In addition, the control unit 240 controls the display unit 240 to display the modeled virtual power plant, virtual device, and accident situation on the screen. In addition, the control unit 230 controls the display unit 240 according to the input of the participating driver to change the screen displayed on the display.

In addition, the control unit 230, based on the information on the modeled virtual power plant and the modeled virtual device, when the participating operator who arrives in the space where the specific virtual device is located inputs an input to operate the specific virtual device, according to the input information The display unit 240 may be controlled to change the state of the virtual device displayed on the display.

Although not shown, the accident situation realizing unit 200 may further include a sound device (not shown) so that the participating drivers can hear sounds that may occur during the action process.

Before describing the available time setting unit 300 , the diagnostic time measuring unit 400 , the moving time measuring unit 500 , and the operating time measuring unit 600 , FIG. 2 is first described for better understanding. is a diagram showing a timeline for securing the validity of the manual action performed by the operator.

The available time refers to the time that an operator can use to take measures to stop the power plant stably in the event of an accident that has a negative impact on the safety shutdown of the power plant. Here, the negative effect on the safety stop may mean an effect on the power plant by not automatically acting for the safety stop of the stable stop device.

That is, the available time may mean a desirable time required to complete manual action for a specific device (a specific virtual device in a virtual power plant) when an accident occurs. For example, the available time indicates that if no manual action is taken on a specific device (or a specific virtual device) from the time the operator recognizes the accident, a derivative accident derived from the occurrence of the accident will occur in the power plant (or virtual power plant). It can mean the time to a point in time.

The diagnosis time is the time consumed from when the operator recognizes the occurrence of an accident until the diagnosis for specifying a specific device (or specific virtual device) requiring manual action is completed. For example, the diagnosis time indicates that the operator recognizes the occurrence of an accident and performs a diagnostic procedure related to the accident to specify a specific device (or specific virtual device) requiring manual action among a plurality of devices (or a plurality of virtual devices). It may be the time consumed by the time the diagnosis is completed.

Alternatively, the diagnosis time may be the time consumed until the operator recognizes the occurrence of an accident and completes the diagnosis for specifying a specific device (or a specific virtual device) based on the operator's engineering knowledge.

The movement time is the time consumed for the operator to move from the initial position to the operation position where the diagnosed specific device (or specific virtual device) is located. That is, the movement time is the time from the time when the operator who has completed the diagnosis of the accident starts to move from the initial position to the operation position to the time when the movement is completed. For example, the initial location may be a main control room.

The operation time (or action time) is the time consumed by the operator to operate a specific device (or a specific virtual device). For example, the operation time may be the time consumed until the operator completes the operation of the specific device (or the specific virtual device).

The spare time (or margin time, or time margin) may mean the remaining time obtained by subtracting the diagnosis time, the movement time, and the operation time from the available time.

When described based on the foregoing, the available time setting unit 300 responds to the accident implemented by the accident situation realizing unit 200, and the available time required until the participating operator completes the manual action for the specific virtual device. to set

For example, the available time setting unit 300 may set the available time based on information obtained by simulating an accident and/or information interpreting the accident by a simulator and/or a computing device installed in a power plant to analyze an accident. .

For example, the available time setting unit 300 may be provided so that the simulator and/or computing device may receive information simulating an accident and/or information interpreting the accident from the simulator and/or computing device.

As another example, the available time setting unit 300 may be provided so that the simulator and/or the computing device and the simulator and/or the computing device can share information simulating an accident and/or information interpreting the accident.

Here, the simulator and/or the calculation device may be a device installed in a power plant to analyze an accident based on a code input by an operator. Specifically, the simulator and/or the calculation device may be provided to analyze the accident based on the safety analysis code or the corresponding operation code.

In the above description, the safety analysis code may be a code or program developed to predict the behavior of a specific power plant system and/or a specific device according to the occurrence of an accident. For example, the safety analysis code is one of various safety analysis codes such as a code for core physics analysis, a code for fuel behavior analysis, a code for analyzing thermal hydraulic behavior, and a code for the analysis of nuclear fission products leaking from nuclear fuel. can be one

In the above description, the operation code corresponding to the safety analysis code may be a code or program developed to predict the behavior of a specific power plant system and/or a specific device according to the occurrence of an accident based on the variables for the accident.

For example, the operation code may be configured to interpret an accident interpreted by the safety interpretation code or an accident similar thereto (hereinafter, 'interpreted accident'). Specifically, the operation code may be configured to predict the behavior of a specific power plant system and/or a specific device according to the occurrence of an accident based on a variable different from the safety analysis code for the analyzed accident.

Or, for example, the opcode may be configured to predict the behavior of a specific power plant system and/or a specific device according to the occurrence of an accident with respect to an accident not interpreted by the safety analysis code.

The available time setting unit 300 may obtain information on the available time from the simulator and/or the computing device, and set the available time for an accident based on the obtained information on the available time. The available time setting unit 300 having set the available time transmits available time data including information on the available time to the action suitability determining unit 700 to be described later.

Also, the available time setting unit 300 may store the available time data including information on the available time analyzed by the simulator and/or the computing device in the database 100 .

In addition, the available time setting unit 300 may include a safe available time setting unit 310 that selects one available time from among a plurality of available times based on the degree of risk set by the user. To this end, the simulator and/or the calculation device may transmit information about a plurality of available times obtained using a plurality of safety analysis codes and a plurality of operation codes to the safe available time setting unit 310 .

Alternatively, for this purpose, the safe available time setting unit 310 may obtain a plurality of available time data analyzed in advance and stored in the database 100 to obtain information on the plurality of available times.

In addition, the safe available time setting unit 310 obtains information about the risk of an accident currently being implemented from the accident situation realizing unit 200 .

The safe available time setting unit 310 that has received the information on the plurality of available times and the information on the degree of risk selects one available time from among the plurality of available times according to the degree of risk and sets the available time. One available time selected from among a plurality of available times is called safe available time. That is, the safe available time may mean an available time determined to be preferable among a plurality of available times according to the degree of risk of an accident.

That is, the safe available time setting unit 300 according to an embodiment of the present invention is set by the user among a plurality of available times obtained by interpreting the same accident in a plurality of methods (a plurality of safety analysis codes and/or operation codes). One available time is selected based on the risk of an accident. Accordingly, the user may set the degree of risk differently according to the severity of the accident, and may set the length of the available time differently for each accident.

In the above-described case, the safe available time setting unit 310 obtains information on the degree of risk from the accident situation realizing unit 200 as an example, but this is exemplary. As another example, the safe available time setting unit 310 may directly receive information on the degree of risk from the user.

A method for the safe available time setting unit 310 to select the safe available time according to the degree of risk may be as follows.

For example, in the case of an accident in which the degree of risk is set to be lower than a predetermined reference value according to a criterion set in advance by the user, the safe available time setting unit 310 sets the longest available time among a plurality of the available safe time setting unit 310 acquired by the user. Time or a similar time may be set as the safe available time.

In addition, in the case of an accident in which the degree of risk is set higher than a certain reference value according to a criterion set in advance by the user, the safe available time setting unit 310 is the shortest time or A similar time can be set as the safe available time.

As another example, the safe available time setting unit 310 may set the available time corresponding to N percentiles among a plurality of available times as the safe available time for an accident having a risk of N set by the user. In this case, when the value corresponding to the N percentile does not exist, the available time having the closest percentile value may be selected as the safe available time.

Specifically, when there are M available times, the available times corresponding to the N percentiles are as follows. First, if M available times are arranged in the order of longest available time, the K-th longest available time corresponds to the (100K/M) percentile. Therefore, the longest available time corresponds to the (100/M) percentile, and the shortest available time corresponds to the 100 percentile.

For example, in the availability time corresponding to the 90th percentile, available times that are longer than the available time corresponding to the 90th percentile in a plurality of available hours are 90% of the total, and the available times that are shorter than the available time corresponding to the 90th percentile are all available times. It means a value that is 10% of

The safe available time setting unit 300 setting the safe available time transmits the safe available time data including information on the safe available time to the action suitability determination unit 700 to be described later.

On the other hand, the diagnosis time measurement unit 400 consumes in the diagnosis step of recognizing the accident and specifying a specific virtual device among a plurality of virtual devices, among the action process of the participating driver simulated by the accident situation realizing unit 200 . Diagnosis time is measured.

For example, a time when a participating operator recognizes an accident may be a time when a warning due to an accident or the like occurs in the virtual power plant. In addition, the time when the diagnosis for specifying the specific virtual device by the participating operator is completed may be the time when the input for inputting the specific virtual device through the input unit is completed.

As shown in FIG. 1 , the diagnosis time measuring unit 400 may include a diagnosis time data recording unit 410 and a safety diagnosis time setting unit 420 .

The diagnosis time data recording unit 410 is a component that records the diagnosis time measured by the participating operator through the diagnosis step and information on the participating operator. For example, the diagnosis time data recording unit 410 may include diagnosis-related information, which is information about the participating driver including the career, driving experience, etc. of the participating driver who simulated the action process, and the diagnosis time required for the participating driver to complete the diagnosis step. It is possible to record or store the diagnosis time data including information about the

Here, the diagnosis-related information may be obtained by a participating operator inputting information through the input unit at a stage in which the simulation by the accident situation realizing unit 200 starts, during the simulation process, or after the simulation is finished.

Although it has been described in the above description that the diagnosis time data recording unit 410 records or stores the diagnosis time data, the present invention is not limited thereto. For example, the diagnosis time data recording unit 410 may be provided to store the diagnosis time data in the database 100 and to obtain the stored diagnosis time data.

The safety diagnosis time setting unit 420 may be a component that repeatedly simulates the diagnosis step and selects one diagnosis time according to a criterion preset by the user from among a plurality of measured diagnosis times. At this time, the selected diagnosis time is called the safety diagnosis time.

That is, the safety diagnosis time setting unit 420 is a component that selects the diagnosis time expected to be consumed in diagnosing the accident when an accident occurring in the virtual power plant occurs in the actual power plant in consideration of the uncertainty of the measured diagnosis time.

Here, the uncertainty means that the diagnosis time may vary each time even when the same person diagnoses the same accident, and when a plurality of drivers diagnose the same accident, the diagnosis time may vary for each operator.

To this end, the safety diagnosis time setting unit 420 acquires a plurality of diagnosis time data recorded in the diagnosis time data recording unit 410 while the diagnosis step is repeatedly simulated from the diagnosis time data recording unit 410 . In addition, the safety diagnosis time setting unit 420 acquires information on the plurality of diagnosis times measured by repeatedly simulating the diagnosis step from the acquired plurality of diagnosis time data.

For example, the plurality of diagnostic times measured while the diagnostic step is repeatedly simulated may be measured by each of a plurality of participating drivers performing the diagnostic step at least once.

The safety diagnosis time may be set corresponding to the degree of risk of each of the plurality of accidents described above. For example, in the case of an accident in which the level of risk is set to be lower than a predetermined reference value according to a criterion set in advance by the user, the safety diagnosis time setting unit 420 sets the longest time among the plurality of diagnosis times acquired by the safety diagnosis time setting unit 420 . Alternatively, a similar time may be set as the safety diagnosis time.

In addition, in the case of an accident in which the degree of risk is set higher than a certain reference value according to a criterion set in advance by the user, the safety diagnosis time setting unit 420 sets the shortest time or A similar time can be set as the safety diagnosis time.

As another example, based on the degree of risk described above in the description of the safe available time setting unit 310, the safety diagnosis time setting unit 420 corresponds to an N percentile among a plurality of diagnosis times for an accident having a risk of N. The diagnosis time can be set as the safety diagnosis time. In this case, when a value corresponding to the N percentile does not exist, a diagnostic time having the nearest percentile value may be selected as the safety diagnostic time. The details of the percentile are the same as described above.

To this end, the safety diagnosis time setting unit 420 may obtain information on the degree of risk of an accident currently being simulated from the accident situation realizing unit 200 . For example, the safety diagnosis time setting unit 420 may receive risk data including information about the risk of an accident currently being simulated from the accident situation realizing unit 200 . Alternatively, the safety diagnosis time setting unit 420 may receive information on the degree of risk from the user.

Meanwhile, the safety diagnosis time setting unit 420 may set a safety diagnosis time for each individual, which is a safety diagnosis time set for each participating driver who has performed the diagnosis step. That is, the individual safety diagnosis time may be set differently for each of the plurality of participating drivers. To this end, the accident situation implementation unit 200 may receive information (hereinafter, 'identification information') for identifying the participating driver. For example, the identification information may be the name of the participating driver, employee number, job title, and the like.

Meanwhile, the diagnosis time data recording unit 410 may obtain identification information from the accident situation realizing unit 200 and store or record the obtained identification information in the diagnosis time data.

A method for the safety diagnosis time setting unit 420 to set the individual safety diagnosis time is as follows. First, the safety diagnosis time setting unit 420 may extract data having the same identification information from a plurality of diagnosis time data and then extract a plurality of diagnosis times from the extracted data.

The safety diagnosis time setting unit 420, which has extracted a plurality of diagnosis times, may average the plurality of diagnosis times as the individual safety diagnosis time. Alternatively, the individual safety diagnosis time may be provided as a value selected according to the degree of risk of an accident among a plurality of diagnosis times. For example, when the risk of an accident is N, a plurality of diagnosis times are counted from a side having a longer diagnosis time, and a diagnosis time corresponding to the N percentile may be selected as the individual safety diagnosis time.

The safety diagnosis time setting unit 420 may store information on the individual safety diagnosis time in the database 100 .

On the other hand, the movement time measurement unit 500 moves from the initial position of the virtual power plant to the operation position where the specific virtual device is installed by the participating operator who has completed the diagnosis step during the action process of the participating operator simulated by the accident situation realizing unit 200 . The moving time, which is the time consumed in the moving moving step, is measured. For example, the initial location may be the main control room of the virtual power plant implemented to correspond to the main control room of the power plant.

When the diagnosis step is completed and the moving step is started, a plurality of paths for moving from the initial position to the manipulation position may be displayed on the display of the display unit 240 . When the participating driver inputs an input to select a specific route from among a plurality of routes, the measurement of the travel time starts.

In an embodiment of the moving step, the participating driver who has selected the route boards the walking unit and starts walking. In this case, the moving speed of the participating driver inside the virtual power plant may be determined based on the walking speed at which the participating driver walks in the walking unit.

On the other hand, the walking unit may adjust the inclination of the conveyor on which the driver is walking according to the path that the participating driver moves. For example, when participating operators climb stairs or slopes within the virtual power plant, the conveyor will slope upwards with respect to the ground. On the other hand, when the participating operator goes down the stairs or slope in the virtual power plant, the conveyor is inclined downward with respect to the ground.

In another embodiment of the moving step, the participating driver does not actually walk using the walking unit, and the moving time may be determined based on the walking information of the participating driver. In this case, the gait information of the participating driver may include information on the gait speed, stride length, etc. of the participating driver measured in advance. In this case, the accident situation realizing unit 200 may obtain the gait information of the participating driver through the user's input or from the moving time data to be described later. In this embodiment, the accident situation implementation unit 200 that has obtained the walking information of the participating driver may determine the moving time in the moving step. For example, in the moving step in this embodiment, a process in which the avatar corresponding to the participating driver moves a specific route in response to the input of the participating driver may be simulated. Alternatively, in this embodiment, the moving step is not simulated and the moving time can be directly derived. For example, when a participating driver selects a specific route from among a plurality of routes, a movement time may be calculated based on length information of the specific route and gait information of the participating driver. For example, the travel time may be calculated as a value obtained by dividing the walking speed of the driver by the length of a specific route.

Meanwhile, as shown in FIG. 1 , the moving time measuring unit 500 may include a moving time data recording unit 510 , a safe moving time setting unit 420 , and a route determining unit 530 .

The moving time data recording unit 510 is a component that records the moving time measured by the participating driver through the moving step and information on the participating driver.

Specifically, the movement time data recorder 510 is information about the participating driver, including age, gender, weight, height, walking speed, stride, and the like, of the driver who simulated the action process, movement-related information, and the driver's movement stage. It is possible to record or store the travel time data including information on the travel time taken to complete and information on the route selected by the participating driver.

Here, among the movement-related information, age, gender, weight, height, etc., the stage at which the simulation by the accident situation realization unit 200 starts, during the simulation process, or after the simulation is finished, the participating driver receives information through the input unit It can be obtained by entering

Meanwhile, among the movement-related information, stride length, walking speed, etc. may be measured and obtained while the participating driver boards the walking unit and walks. Alternatively, the stride length, walking speed, etc. of the movement-related information may be obtained by inputting information through an input unit by a participating driver at a stage in which the simulation is started, during the simulation process, or after the simulation is finished.

On the other hand, as described above, the accident situation realizing unit 200 may acquire the walking information of the participating driver based on the movement time data. For example, the accident situation realization unit 200 may acquire the movement time data from the movement time data recording unit 510 . Thereafter, the accident situation realization unit 200 may acquire the walking information of the participating driver based on the movement time data.

Although it has been described in the above description that the moving time data recording unit 510 records or stores the moving time data, the present invention is not limited thereto. For example, the moving time data recording unit 510 may be provided to store the moving time data in the database 100 and to obtain the stored moving time data.

The safe movement time setting unit 520 is a component that repeatedly simulates the movement step and selects one movement time according to a criterion preset by the user from among a plurality of measured movement times. At this time, the selected travel time is called the safe travel time.

That is, the safe movement time setting unit 520 is a component that selects the expected movement time to move from the initial position to the operation position when an accident occurring in the virtual power plant occurs in the actual power plant, in consideration of the uncertainty of the measured movement time. .

In the above description, the uncertainty of the travel time means that even when the same person moves on the same route, the travel time may vary each time, and when a plurality of drivers move on the same route, the travel time may vary for each driver.

To this end, the safe movement time setting unit 520 acquires a plurality of movement time data recorded in the movement time data recording unit 510 by repeatedly simulating the movement step from the movement time data recording unit 510 . In addition, the safe movement time setting unit 520 acquires information on the plurality of movement times measured by repeatedly simulating the movement step from the plurality of movement time data obtained.

For example, the plurality of moving times measured while the moving step is repeatedly simulated may be measured by each of a plurality of participating drivers performing the moving step at least once.

The safe travel time may be set in response to the degree of risk of each of the above-described plurality of accidents. For example, in the case of an accident in which the degree of risk is set to be lower than a certain reference value according to a criterion set in advance by the user, the safe travel time setting unit 520 sets the safe travel time setting unit 520 for the longest time among a plurality of travel times obtained by the user. Alternatively, a similar time can be set as the safe travel time.

In addition, in the case of an accident in which the degree of risk is set higher than a certain reference value according to a criterion set in advance by the user, the safe travel time setting unit 520 sets the shortest time or A similar time can be set as the safe travel time.

As another example, based on the level of risk described above in the description of the safe available time setting unit 310, the safe travel time setting unit 520 corresponds to the N percentile among a plurality of moving times for an accident having a risk of N. The travel time can be set as the safe travel time. In this case, when a value corresponding to the N percentile does not exist, a movement time having the closest percentage value may be selected as the safe movement time. The details of the percentile are the same as described above.

To this end, the safe travel time setting unit 520 may obtain information on the degree of risk of an accident currently being simulated from the accident situation realizing unit 200 . For example, the safe travel time setting unit 520 may receive risk data including information on the risk of an accident currently being simulated from the accident situation realizing unit 200 . Alternatively, the safe travel time setting unit 520 may receive information on the degree of risk from the user.

Meanwhile, the safe travel time setting unit 520 may set a safe travel time for each individual, which is a safe travel time set for each participating driver who has performed the moving step. That is, the individual safe travel time may be set differently for each of the plurality of participating drivers. To this end, the accident situation realizing unit 200 may receive information for identifying the participating driver. Meanwhile, the moving time data recording unit 510 may obtain identification information from the accident situation realizing unit 200 and store or record the obtained identification information in the moving time data.

A method for the safe travel time setting unit 520 to set the individual safe travel time is as follows. First, the safe movement time setting unit 520 may extract data having the same identification information from a plurality of movement time data and extract a plurality of movement times from the extracted data.

The safe movement time setting unit 520 that has extracted a plurality of movement times may average the plurality of movement times as the safe movement time for each individual. Alternatively, the individual safe travel time may be provided as a value selected according to the degree of risk of an accident among a plurality of travel times. For example, when the risk of an accident is N, a plurality of moving times are counted from the longer moving time, and a moving time corresponding to the N percentile may be selected as the safe moving time for each individual.

The safe travel time setting unit 520 may store information on each individual safe travel time in the database 100 .

The route determination unit 530 may be a component that determines the recommended route based on the time consumed by the participating driver moving each route included in the plurality of routes connecting the operation locations from the initial location.

Specifically, the route determination unit 530 calculates or selects a route travel time expected to be consumed by an arbitrary driver to move each route, based on the movement time data stored in the movement time data recording unit 510 . To this end, the moving time data recording unit 510 may store, in the moving time data, information on the selected path, which is the path selected by the participating driver in the moving step, among a plurality of paths.

In more detail, first, the path determining unit 530 extracts a plurality of moving times based on a plurality of moving time data having the same information on a selected path from the plurality of moving time data. The path determining unit 530 calculates or selects a path moving time for the selected path based on the plurality of extracted moving times.

For example, the route travel time of the selected route may be calculated as an average value of a plurality of extracted travel times. Alternatively, the path moving time of the selected path may be selected as the longest time among the plurality of extracted moving times.

The route determination unit 530 calculates or selects a route movement time for each selected route, and compares the route movement time to determine a recommended route. For example, the recommended path may be a selection path having the shortest path movement time value among a plurality of selection paths.

Alternatively, the recommended routes may be selected routes having a route movement time that falls within a time range set by the user. In this case, there may be a plurality of recommended routes.

Meanwhile, the route determining unit 530 stores information on the determined recommended route in the recommended route database 120 .

The operation time measurement unit 600 may start to measure the operation time when the operator reaches the operation position in the virtual power plant of the participating operator. The operation time measurement unit 600 measures the time consumed until the participating driver sees the screen displayed on the display and operates the virtual specific device to complete the manual action.

For example, the operation time measurement unit 600 may measure the time consumed in the operation step in which the participating operator views the image displayed on the display and operates the specific virtual device through the input unit. Alternatively, the operation time measurement unit 600 may measure the time consumed by the participating driver operating a specific virtual device expressed in augmented reality in the operation step.

The operation time data recording unit 610 is a component that records the operation time measured by the operator participating in the operation step and information on the operator participating. For example, the operation time data recording unit 610 may include operation-related information that is information about the participating driver including the career, driving experience, operation experience with respect to a specific device, operator training information, and the like of the participating driver simulating the action process. It is possible to record or store the operation time data including information on the operation time taken to complete the operation step by the operator and the participating operator.

Here, the manipulation-related information may be obtained by a participating operator inputting information through the input unit at a stage in which the simulation by the accident situation realizing unit 200 starts, during the simulation process, or after the simulation is finished.

The safe operation time setting unit 620 may be a component in which the operation step is repeatedly simulated and selects one operation time according to a criterion preset by the user from among a plurality of measured operation times. In this case, the selected operation time is called the safe operation time.

That is, the safe operation time setting unit 620 is a component that selects the operation time expected to be consumed in operating a specific device when an accident occurring in the virtual power plant occurs in the actual power plant in consideration of the uncertainty of the measured operation time. .

In the above description, uncertainty means that even when the same person operates the same equipment, the operation time may vary each time, and when a plurality of operators operate the same equipment, the operation time may vary for each operator.

To this end, the safe operation time setting unit 620 acquires a plurality of operation time data recorded in the operation time data recording unit 610 by repeatedly simulating the operation step from the operation time data recording unit 610 . In addition, the safe operation time setting unit 620 acquires information about the plurality of operation times measured by repeatedly simulating the operation step from the acquired plurality of operation time data.

For example, the plurality of diagnostic times measured while the manipulation step is repeatedly simulated may be measured by each of a plurality of participating drivers performing the manipulation step at least once.

The safe operation time may be set corresponding to the degree of risk of each of the plurality of accidents described above. For example, in the case of an accident in which the degree of risk is set to be lower than a predetermined reference value according to a criterion set in advance by the user, the safe operation time setting unit 620 is the longest time among a plurality of operation times obtained by the safe operation time setting unit 620 Alternatively, a similar time may be set as the safe operation time.

In addition, in the case of an accident in which the degree of risk is set higher than a certain reference value according to a criterion set in advance by the user, the safety operation time setting unit 620 is the shortest time or A similar time can be set as the safe operation time.

As another example, based on the degree of risk described above in the description of the safe available time setting unit 310, the safe operation time setting unit 620 corresponds to the N percentile among a plurality of operating times for an accident having a risk of N. The operation time can be set as the safe operation time. In this case, when a value corresponding to the N percentile does not exist, the operation time having the nearest percentile value may be selected as the safe operation time. The details of the percentile are the same as described above.

To this end, the safe operation time setting unit 620 may obtain information on the degree of risk of an accident currently being simulated from the accident situation realizing unit 200 . For example, the safe operation time setting unit 620 may receive risk data including information about the risk of an accident currently being simulated from the accident situation realizing unit 200 .

First, the safe operation time setting unit 620 may extract data having the same identification information from a plurality of operation time data, and then extract a plurality of diagnosis times from the extracted data.

The safe operation time setting unit 620 that has extracted a plurality of operation times may average the plurality of operation times as a safe operation time for each individual. Alternatively, the individual safe operation time may be provided as a value selected according to the degree of risk of an accident among a plurality of operation times. For example, when the risk of an accident is N, the operation time corresponding to the N percentile may be selected as the individual safe operation time by counting a plurality of operation times from the longer operation time.

On the other hand, the action possibility determination unit 800 obtains information on the recommended route stored in the recommended route database 120 and provides information on the recommended route to the operator located in the main control room when a similar accident occurs based on the information on the recommended route. may be provided to provide.

In addition, the action possibility determination unit 800 may be provided to recommend a route in consideration of the current state of the power plant. The action possibility determining unit 800 may receive in advance information on a currently usable path and an unavailable path from the user. The unavailable path may be, for example, a path currently restricted in access or a path in which access is restricted due to an accident.

The action possibility determining unit 800 may be provided to recommend a route that is expected to take the shortest time to move to a specific device from among currently available routes by comparing the movement times of a plurality of routes based on the movement time data.

On the other hand, the action possibility determination unit 800 may be provided to check the available manpower located in the main control room in the event of a fire based on the fire abnormal procedure document and to recommend an action for the fire.

According to the system 1 for securing the reliability of the operator's manual action according to an embodiment of the present invention, the timeline related to the manual action is verified to obtain a valid manual action.

In addition, by conservatively setting the safe available time, safety diagnosis time, safe travel time, and safe operation time, it is possible to secure a manual action method that can be executed regardless of who the operator is located in the main control room. For example, even if the safe available time is set to the shortest time and each of the safety diagnosis time, safe travel time, and safe operation time is set to the longest time, if a manual action method that successfully stops the power plant is obtained, it is recorded in the abnormal procedure related to the accident. This has the effect of stably taking manual measures in case of an actual accident.

On the other hand, when the spare time has a negative value by setting the safe available time as the shortest time, the user may reset the safe available time, safety diagnosis time, safe travel time and/or safe operation time. The user can reflect the manual action method that is expected to be successful in the manual action by the operator with the greatest number of manual actions in which the slack time has a positive value in the abnormal procedure.

Hereinafter, a method for securing reliability of an operator's manual action according to an embodiment of the present invention will be described.

3 is a flowchart of a method for securing reliability of an operator's manual action according to an embodiment of the present invention. As shown in FIG. 3 , the method for securing reliability of the operator's manual action according to an embodiment of the present invention includes a step (S10) of realizing a situation in which an accident has occurred, a step of setting the available time (S20), and a step of measuring the diagnosis time Step (S30), the step of measuring the movement time (S40), the step of measuring the operation time (S50), the step of determining the suitability of the manual action (S60), and the step of providing a guideline for the accident (S70) may include

First, the participating driver selects a scenario for a desired accident situation using the input unit. For example, a scenario corresponding to a plurality of scenario data may be displayed on the display. When a participating driver inputs to select one scenario from among a plurality of scenarios, the accident situation implementation unit 200 implements an accident situation based on scenario data corresponding to the selected scenario.

Specifically, the virtual power plant and the virtual machine are modeled by the modeling unit 210 . In addition, the modeling unit 210 models and implements a situation in which an accident occurs in the virtual power plant based on the scenario data.

For example, a time when a participating operator recognizes an accident may be a time when a warning due to an accident or the like occurs in the virtual power plant. For example, the warning may be visually displayed on the display unit or provided as a warning sound generated by an acoustic device.

In addition, the time when the diagnosis for specifying the specific virtual device by the participating operator is completed may be the time when the input for inputting the specific virtual device through the input unit is completed. For example, the user may complete the diagnosis step by inputting an input for selecting one of a plurality of virtual devices displayed on the display. Alternatively, the user may complete the diagnosis step by inputting a code corresponding to a specific virtual device through the input unit.

In the step (S40) in which the movement time is measured, the participating operator conducts a simulation corresponding to the accident by the movement time measurement unit 500, and the time consumed to move from the initial position in the virtual power plant to the operation position where the specific virtual device is installed This is measured

The time point at which the measurement of the travel time is tried may be a time point when a participating driver inputs an input for selecting one route among a plurality of routes. For example, an option may be given to select one of a plurality of routes on the display, and the driver may input a corresponding input to select the route. Alternatively, a route may be selected by an operator inputting a code corresponding to a specific route.

On the other hand, the time at which the measurement of the movement time is terminated may be the time when the participating driver arrives at the operation position.

In an embodiment, the time until the virtual avatar controlled by the driver moves from the initial position to the manipulation position may be the movement time. In this embodiment, modeling data for the virtual avatar may be stored in the database 100 and modeled by the modeling unit 210 .

In another embodiment, the driver boards the walking unit, and the controller 230 may control the scenery of the virtual power plant displayed on the display unit 240 to change in response to the walking speed at which the driver walks on the walking unit. For example, the controller 230 may control the scenery displayed on the display 240 to be changed in proportion to the walking speed.

In step S50 in which the operation time is measured, the participating driver performs a simulation corresponding to the accident by the operation time measurement unit 600, and the time consumed to operate the specific virtual device at the operation position is measured.

The time point at which the measurement of the operation time is tried is when the participating operator arrives at the operation position. The point at which the measurement of the operation time ends is the point when the participating operator completes the manual action for the specific virtual device.

In an embodiment, the operation time measuring unit 600 may measure the time until the virtual avatar controlled by the driver receives an input from the participating driver and completes the manual action.

In another embodiment, the operation time measurement unit 600 may measure the time until the operator completes the manual action for the specific virtual device using the augmented reality equipment.

In the step S60 in which the suitability of the manual action is determined, the action suitability determining unit 700 calculates the spare time, and the appropriateness of the manual action simulated by the participating operator in response to the accident is determined based on the spare time. In this step, the action suitability determination unit 700 stores manual action data including information on the operator's manual action determined to be appropriate in the manual action database 130 . In addition, in this step, the action suitability determination unit 700 may reflect the information on the manual action determined to be appropriate to the abnormal procedure of the related accident.

In the step S70 in which the guideline for the accident is provided, when an actual accident occurs in the power plant, the action possibility determination unit 800 presents a guideline for the accident.

For example, it is possible to present information to the operator about the manual action determined to be appropriate for the same or similar accident. Alternatively, for example, a route to a specific device may be recommended to the driver. Or, for example, it may recommend an operator to perform the diagnosis step, the moving step, and/or the operation step.
