The interactive simulation system 10 for plant safety training according to the present embodiment may be a computer device, and the interactive simulation system for plant safety training according to the embodiment may be entirely hardware, or partially hardware and partially software. Can have That is, the interactive simulation system for plant safety training and each unit included therein may collectively refer to a device for storing data of a specific format and content or transmitting and receiving an electronic communication method, and related software.

In addition, in this specification, each part constituting the interactive simulation system for plant safety training is not intended to refer to a separate component that is physically separated. That is, in FIG. 1, each part of the interactive simulation system for plant safety training is illustrated as a separate block that is separated from each other, but this is functionally divided by the operation executed by the interactive simulation system for plant safety training. Depending on the embodiment, some or all of the above-described parts may be integrated in the same one device, or one or more parts may be implemented as separate devices physically separated from other parts. For example, each part may be components communicatively connected to each other under a distributed computing environment.

The safety accident data generated in the interactive simulation system 10 for plant safety training may be provided to the VR system 20. The VR system 20 may provide a plant virtual environment to an operator. The VR system 20 may reflect accident result data provided from the interactive simulation system 10 to the plant virtual environment and provide it to the worker. The worker can perform the action according to the accident result data in the virtual space, and the action by the worker is reflected as the VR numerical adjustment value and can be fed back to the interactive simulation system 10. The accident situation generated by the interactive simulation system 10 may be changed according to the action by the operator, and the interactive simulation system 10 may transmit the changed accident data back to the operator.

It can be. Hereinafter, each configuration of the interactive simulation system 10 will be described in more detail.

The process simulation unit 110 may model each of the plant's steady state process simulation and dynamic process state simulation. 2A is a steady state simulation model process flow diagram, and FIG. 2B is a dynamic process simulation model process flow diagram.

Here, the plant simulated by the process simulation unit 110 may be a petrochemical plant, and the target process may be an RDS process. RDS (Residue De-Sulfurization) process removes impurities contained in AR (Atmospheric Residue) generated in the Crude Distillation Unit (CDU) to decompose the low-sulphur heavy oil in the rear stage into a fluidized bed catalytic reaction. This is a process for producing raw materials for the FCC (Fluidized Catalytic Cracking) process, which is a process for producing gasoline and diesel. The RDS process is a process with a temperature of 400 ° C or higher in the reactor and a pressure of 200 atm (ultra-high pressure corresponding to a depth of 2,000 m) .It is a process using a catalyst, so it is operated annually for catalyst replacement work according to the catalyst life (about 11 months). The stop must be repeated. Accordingly, according to this, it is frequently required to deviate from the normal state, and thus the risk of an accident is relatively high.

The process simulation unit 110 may model a steady state process simulation by performing modeling including a range from the rear end of the reactor to the rear end of the atmospheric distillation column. As shown in FIG. 2A, the steady-state process simulation is modeled to measure the product of the fractionator at the end and assume it as the output of the reactor, and inject it into the feed of the HHPS at the front end. After CLPFD, finally through Atmospheric Fractionator, it ends as a product.

The process simulation unit 110 may model a dynamic process state simulation capable of dynamic simulation based on a steady state process model. That is, as shown in FIG. 2B to the steady state process model, a plurality of controllers for controlling the height parameters of the liquid such as temperature, pressure, flow rate, etc. are added to implement modeling of dynamic process state simulation. Cascade control is applied to the control structure, and a virtual control device for implementing a gradual change of a plurality of specific variables (valve opening, valve opening, etc.) for applying an accident scenario can also be implemented in dynamic process state simulation.

The process simulation unit 110 may perform dynamic process simulation according to the received accident scenario. The interactive simulation unit 120 may include a plurality of accident scenarios, and these accident scenarios are related to adjusting each controller and controlling specific variables of the dynamic public simulation. For example, the control of the controller and specific parameters may include malfunction of the controller, opening of the valve, etc., and accidents may occur when the state is continuously left without proper action by the operator. As described above, since the controller and the specific variable are also plural, the interactive simulation unit 120 may provide the accident simulation scenario of a wide variety of cases to the process simulation unit 110. The process simulation unit 110 may perform dynamic process simulation according to the received accident scenario, and process variables (T: temperature, P: pressure, F: flow rate) of the plant configuration change in real time according to the dynamic process simulation. do. In addition, process variables (T: temperature, P: pressure, F: flow rate) may be changed according to the operator's operation in the virtual space. That is, the accident in the accident scenario may be resolved according to the proper manipulation in the virtual space of the worker. That is, the process simulation unit 110 may perform dynamic process simulation over time in the provided accident scenario, but receive the operator's manipulation in the virtual space and reflect it in the dynamic process simulation.

3 is an exemplary diagram schematically showing an operation screen of the interactive simulation unit 120.

In the interactive simulation system 10, the interactive simulation unit 120 mediates transmission and reception of data between the process simulation unit 110 and the accident simulation 130. In addition, the interactive simulation unit 120 may receive a dynamic process simulation result (process variable) in real time and transmit it to the accident simulation 130. The process variable by the dynamic process simulation may be an input value of the accident simulation 130. The interactive simulation unit 120 may receive a simulation result (process variable) from the process simulation unit 110 in a form of possible data utilized by the accident simulation unit 130 and provide it to the accident simulation unit 130. For example, the simulation result (process variable) data may be a document file in the form of a spreadsheet, and the interactive simulation unit 120 may include a program capable of working with a document file in the form of a spreadsheet, and the interactive simulation unit Both the 120 and the accident simulation unit 130 may include a computer program capable of interworking with the spreadsheet document work program in real time. That is, plant process simulation and accident simulation can be organically fused through the interactive simulation unit 120.

In addition, the interactive simulation unit 120 may display dynamic process simulation results received in real time on a status screen. FIG. 3A exemplarily shows a state in which scenario 1 is being simulated by the process simulation unit 110. The interactive simulation system 10 can receive the process parameters of each component (FURNACE, Reactor, High Pressure Separator, Gas Detector, etc.) of the plant from the process simulation unit 110, respectively, and can display the status of each. . That is, the dynamic process simulation state of the plant being performed by the process simulation unit 110 may be monitored through a status screen provided by the interactive simulation unit 120. In addition, the control of the controller and the variables of the process simulation unit 110 may be possible in the interactive simulation unit 120. Through the screen input window of the interactive simulation unit 120, the administrator can command a change in process conditions of the process simulation unit 110 and execution, stop, update, etc. of the simulation.

In addition, the interactive simulation unit 120 may be connected to the VR system 20 to transmit the accident data received from the accident simulation unit 130 in real time to update the accident progress state of the VR system 20, and the VR system The operation of the operator provided in (20) may be provided to the process simulation unit 110. In addition, the interactive simulation unit 120 may provide a VR link capable of displaying a screen provided to a worker in the VR system 20 and a worker's gaze screen.

In addition, the interactive simulation unit 120 may indicate an accident progress by displaying an accident result provided from the accident simulation unit 130 on a screen. The result of the accident may be a 3D image image of a rendered plant. The interactive simulation unit 120 may not only visually display the 3D structure of the plant process, but also visually display the result with a legend when an accident (leakage, fire, explosion, etc.) occurs. In addition, the accident result data can be provided to the VR system 20 to reflect the progress of the accident in the virtual system.

The accident simulation unit 130 may receive data on process variables from the interactive simulation unit 120 and query the corresponding accident results in a database to provide the retrieved accident result data to the interactive simulation unit 120. . The accident simulation unit 130 may include a database in which a plurality of accident result data corresponding to accident scenarios and process variables are built. The number of process variables that can be derived according to the scenario and the process variable results that change according to the operator's choice are limited, so the plant accident result data according to each process variable for each scenario can be constructed in advance. For example, when a dynamic public simulation is performed under a specific condition in response to scenario 1, a leakage accident may occur at a specific site if there is no action at the appropriate time.

In addition, the plant accident result data of the accident simulation unit 130 may include data visualizing the plant according to the accident. The visualized data may be 3D rendered image data of the plant. That is, the accident simulation 3D rendering image according to each process variable for each scenario may be stored in the database of the accident simulation unit 130 in advance. Delay in time that may occur when performing real-time rendering may be prevented by providing a 3D rendering image prepared in advance according to process variable conditions. The accident simulation unit 130 may provide the accident simulation data corresponding to the currently provided process variables and scenarios to the interactive simulation unit 120. The interactive simulation unit 120 may quickly display the 3D rendered image provided without delay due to image rendering. 3B is an exemplary screen displaying a 3D rendered image in a separate pop-up window. The 3D rendered image may be displayed as a separate pop-up window, but is not limited thereto, and may also be displayed on a screen indicating a process state.

That is, accident simulation result data according to process variables generated through the dynamic process simulation of the plant can be provided to the worker organically, and more effective training of the worker is possible.
