Description

  The present invention relates to a plant simulation device and a plant simulation system for operation training that are used for operation training by simulating plant processes and control devices.

  For example, in order to ensure stable operation of a power plant such as a chemical process plant, nuclear power, and thermal power, plant process characteristics, a control device, and an operation device are simulated by a plant simulation device and used for operation training. In such operation training with a plant simulation device (simulator) for operation training, learning and training of start / stop in accordance with the operation procedure of the actual plant (actual plant) is performed, and it may happen in the plant by any chance. An expected abnormal event is generated by a simulator, and the corresponding operation and measures are trained.

  Operational training is necessary to increase the effectiveness of the training so that the training conditions are close to those of the actual plant. When the simulated situation is close to the actual plant condition and operation conditions, the sense of reality is enhanced. That is, the temperature, pressure, flow rate, radiation sensor readings, and switch status of the plant operating state are close to the actual plant operating state, as well as the number of operating crews (operators) and the actual work It is desirable to match the driving situation.

  While an environment close to an actual plant is desired, when an actual plant is targeted, the simulation range is wide, and it is desirable to restore the entire environment as a simulation. There is a limit. On the other hand, in driving training, prior desk learning, training using a simulator, reflection / review after training are important, and it is important that individual trainees can repeat operations.

For plant simulators used for operation training of such chemical process plants and nuclear power plants,
As for the plant simulator used for operation training of such a chemical process plant or nuclear power plant, the plant simulator has a plurality of different plant dynamics simulation means, and one plant operation used by a switching signal from the operator. Some characteristic simulation means are selected and executed so that a plurality of plant dynamic characteristics can be simulated and displayed by one facility (for example, see Patent Document 1).
Japanese Patent No. 3472084

  However, the conventional plant simulation device does not have a plurality of simulation means for the control device, operation panel, and interlock that make up the plant, so it has to be simulated by a single plant control device, etc. become.

  In addition, when simulating one plant, if there is a signal exchange or input / output of a process amount with a related plant, this is substituted with a fixed value or a simulation function. In such a case, the influence on the process of the related plant cannot be grasped, and the communication training with the operator of the related plant cannot be sufficiently performed.

  An object of the present invention is to provide a plant simulation device and a plant simulation system that can perform training for cooperation between plants and individual training at the same time, improve the economics of the training, and thus improve the safety of plant operation. It is in.

Means 13a-13n. The simulated plant setting file 14 stores plant information simulated by the plant dynamic characteristic simulation means 12a to 12n and initial data of each simulated plant. The simulated plant switching means 15 is input from an operator input from the input device 16. In response to the switching request, the simulated plant setting file 14 is read, and the plant dynamic characteristic simulation means 12a to 12n and the plant logic simulation means 13a to 13n corresponding to the simulation plant are switched.

  That is, when a simulation plant selection signal is input from the input device 16, the simulation plant switching means 15 receives model parameters and initial values of the simulation plant from the simulation plant setting file 14. Also, the simulated plant switching means 15 selects a corresponding one from the plurality of plant dynamic characteristic simulation means 12a to 12n and plant logic simulation means 13a to 13n prepared in the simulation unit 11, and selects the selected plant dynamic characteristic simulation. The means 12i and the plant logic simulation means 13i are executed.

  The plant dynamic characteristic simulation means 12a to 12n input the operation signal a of the plant from the control panel 17, calculate the dynamic characteristics of the process, that is, mass balance, heat balance, radioactivity, etc., temperature, pressure, density, flow rate, etc. The process signal (process instrumentation value) b is output. The plant logic simulation means 13a to 13n simulate the control logic and interlock of the target plant corresponding to the plant dynamic characteristic simulation means 12a to 12n, and interlock / control signals (interlock signals and equipment operation signals). c is output.

  The process data file 18 writes the process signal b input from the plant dynamic characteristic simulator 12a to 12n and the interlock / control signal c input from the plant logic simulator 13a to 13n into the process data file 18. The process display means 19 sends these signals d to the control panel 17 and displays them on a separately prepared display device 20.

  As shown in FIG. 2, the control panel 17 includes a screen display device 21, an instrument 22, an operation switch 23, and the like, displays a plant state, and operates the plant with the operation switch 23. The signal operated by the operation switch 23 and the output of the controller are input to the simulation unit 11 including the plant dynamic characteristic simulation means 12a to 12n and the plant logic simulation means 13a to 13n, and the plant state is simulated every hour.

  The display device 20 prepared separately displays plant characteristics as necessary, and may be used by a training instructor to grasp the simulation contents.

  According to the first embodiment, since a plurality of plant logic simulation means 13a to 13n are prepared and the plant logic is also switched, the target plant is simulated efficiently and without interfering with other prepared plants. be able to. Therefore, cooperation training between plants and individual training can be performed simultaneously.

  Next, a second embodiment of the present invention will be described. FIG. 3 is a block diagram of a plant simulation system according to the second embodiment of the present invention. In FIG. 3, it has two plant simulation apparatuses in the first embodiment shown in FIG. 1, and communicates process data Ae, Be between plants between each plant simulation apparatus, and performs a simulation in cooperation with each other. Do. FIG. 3 shows A-system and B-system plant simulators. In the A system and the B system, the same parts as those in FIG.

  The two plant simulators of the A system and the B system simulate the respective plants and at the same time communicate the transfer data of the process amount between the plants, simulate the interference between the plants, and perform cooperative training. The transfer data communicated between the simulation units 11A and 11B includes the flow rate, components, temperature, and the like in the case of liquid transfer.

  When simulating the plurality of plants at the same time, simulation may be performed using a part of each of the prepared control panels 17A and 17B. This is particularly effective when the control panels 17A and 17B are each composed of a combination of control panel units having similar functions.

  FIG. 4 shows an example of the allocation of the control panel units 24 of the control panel 17 when simulating the plant A and the plant B in cooperation. In general, there are many cases where the plants are loosely connected to each other. Therefore, in the second embodiment, the plant is particularly called a facility.

  The control panel 17 is composed of ten control panel units 24a to 24j having the same function. In the simulation of the facility A composed of the processes A-1 to A-3, the control panel units 24a to 24e are used. The control panel units 24a to 24e are also used in the simulation of the facility B including the processes B-1 to B-3.

  On the other hand, since the control panel units 24f to 24j are vacant, the steps A-1 to A-3 are performed in the control panel units 24a to 24e and the processes B-1 to B-3 are performed in the control panel units 24f to 24j as shown in FIG. By allocating to, a simulation in which the two plants, facility A and facility B, are linked is possible.

  FIG. 5 shows the relationship between the two simulation units 11A and 11B and the control panel unit 24. There may be two or more plants to be simulated. FIG. 6 shows the relationship between the three simulation units 11A, 11B, and 11C and the control panel unit 24. FIG. 7 shows an example in which four or more plant simulation units 11 </ b> A to 11 </ b> I and the control panel unit 24 are in a one-to-one correspondence.

  According to the second embodiment, since simulation is performed across two plants, communication between two related plants can be trained, which is effective as a communication training. In addition, by selecting the correspondence between the simulation unit and the control panel unit, for example, in the case of one-to-one correspondence, it is possible to divide the simulation unit finely, and many people can train at the same time. it can.

  Next, a third embodiment of the present invention will be described. FIG. 8 is a block diagram of a plant simulation system according to the third embodiment of the present invention. In the third embodiment, in addition to the process data between plants, the simulator parameters f of the plant simulator are communicated between the plant simulators in cooperation with the second embodiment shown in FIG. Thus, the simulation is performed. The same elements as those in FIG. 3 are denoted by the same reference numerals, and redundant description is omitted.

  In FIG. 8, the simulator parameter f of the plant simulation device includes any one of simulation time, set multiplication rate, simulator operation signal, simulator stop signal, and initial state setting signal.

  That is, in the simulation of cooperation between plants, in addition to the process data Ae, a simulator parameter f (simulation time, which is the simulator parameter f, a magnification of a set double speed, a simulator operation signal, a simulator stop signal, and an initial state setting signal) connect.

  The plant simulation device has a double speed function for speeding up the progress of plant dynamic characteristics in real time in order to efficiently perform training that takes a long time in the actual plant. However, when simulating two plants in cooperation, there is a possibility that a difference in time occurs between the two plants if the simulation speed is different. Therefore, a simulator control signal, such as a simulation time or a double speed command, is sent from the plant simulation device of the main first plant to another second plant simulation device, and the second plant simulation device transmits these simulators. Operate in response to parameter f.

  According to the third embodiment, in addition to the effects of the second embodiment, one plant simulator operates in response to the simulator parameter f from the other plant simulator, so both are synchronized and accurate. Simulation can be performed and driving training can be performed properly.

  Next, a fourth embodiment of the present invention will be described. When the contents to be displayed on the screen display device 21 of the control panel unit 24 are limited, or when only important equipment is targeted for simulation from the contents of training, the simulation contents such as the screen display device 21 and the switch are out of the simulation range. Things occur. Therefore, a simulation level database indicating a simulation level of the display signal displayed on the screen display device 21 of the control panel 17 is provided, and the operating device and the measuring instrument are simulated on the screen display device 21 of the control panel 17 with reference to the simulation level database. The level is also displayed.

  FIG. 9 shows the relationship between the dynamic characteristic model and the database of the dynamic characteristic model. Conventionally, data based on the dynamic characteristic model 25 has been directly passed to the control logic 29 and the screen display device 21 via the dynamic characteristic model database 26, the analog data table 27, and the logic database 28. However, in the fourth embodiment, A field indicating an input destination is added to the analog data table 27 as a simulation level database 30 and searched from the screen display device 21 or the control logic 29 to determine the setting source.

  Data from the dynamic characteristic model 25 is stored in the dynamic characteristic model database 26. For those set in the dynamic characteristic model database 26, an index (1) is set in the simulation level database 30, and the dynamic characteristic model is set. Index (2) is set for those which are unrelated to 25 and indicate only the initial value.

  By searching this data field (simulated level database 30), when the setting source is not a dynamic characteristic model but only a simple initial value is set, for example, a simulation is performed on a display signal display screen as shown in FIG. Display out of range.

  According to the fourth embodiment, when the content to be displayed on the screen display device 21 of the control panel unit 24 is limited, or when only important equipment is targeted for simulation from the content of training, the screen display device 21 or Even if the simulation content such as a switch is out of the simulation range, the simulation level can be displayed together.

  Next, a fifth embodiment of the present invention will be described. The fifth embodiment relates to a method for generating a dynamic characteristic model and a display screen. In the fifth embodiment, when generating a dynamic characteristic model, individual programs (modules) of devices such as tanks and pipes are created as elements of a block diagram.

Based on the information in these modules and the block diagram data file 34, the block diagram creation / connection means 33 connects these to construct a process model. The constructed process model is represented by a block diagram, but these entities are module connection relationships and are stored in the block diagram connection data file 35.

  The program code generation means 36 generates a simulation unit program from the block diagram connection data stored in the block diagram connection data file 35 and stores it in the program source file 37. The program source stored in the program source file 37 is input to the plant dynamic characteristic simulating means 12 through the compile link 39 together with the module library 38. The initial values and constants defined in the block diagram are dropped in the initial value data file 40 and the parameter file 41 and used for the simulation by the plant dynamic characteristic simulation means 12.

  On the other hand, since the block diagram connection data stored in the block diagram connection data file 35 includes the contents of the screen display of the block diagram, it is generated by the display screen generating means 42 as a screen fixed screen generated thereby, and the screen display device 21.

  FIG. 12 is an explanatory diagram of an example in which the clarification process is generated according to the fifth embodiment. A process model is configured by pasting equipment parts.
