FIG. 20 is a diagram showing the structure of a plant simulation device. In FIG. 20, the operation unit 110 attached to the simulated operation panel 4 includes an operation switch 112 and a status display lamp 111.
It consists of When this operation device 110 is used as a valve opening / closing operation device, the signal of the operation switch 112 is an open operation signal (O
S1) and the closing operation signal (OS2). These operation signals are transmitted through the signal input / output means 113 to the plant characteristic calculation unit.
Passed to 108. The plant characteristic calculation unit 108 includes a sequence simulation unit 114 that simulates a sequence control device, an operation end simulation unit 115 that simulates the operation of the operation end, and a process simulation unit 116 that calculates the process characteristics based on the state of the operation end. It

In the plant characteristic calculation unit 108, the opening / closing operation signal (OS1, O1 input from the signal input / output unit 113 is input.
S2) is sent to the sequence simulating unit 114 and, for example, after interlocking with a ground fault detection relay, an overload protection relay, etc., an operating signal simulating unit 115 is output as an open signal or a closed signal.
Sent to Further, the plant characteristic calculation unit 108 outputs it as a return signal of an open signal or a closed signal via the signal input / output means 113, and outputs a dot of the status display lamp as an open lamp lighting signal (LS1) or a closed lamp lighting signal (LS2).

The operating end simulation unit 115 receives the open signal and the close signal, and obtains the opening of the valve, for example, by time-integrating the open signal. In response to the opening (OP) of this valve, the process simulation section 116 simulates the flow rate pressure.

When a failure is simulated, conventionally, the PID and the failure state to be simulated are input from the instructor dialogue processing device 1. The failure information is input by the failure simulation dialogue means 104 via the input / output means, and the failure simulation generation means 105 rewrites the failure state storage unit 106. In the execution of such a failure simulation, the instructor uses the data point number (P
I had to know my ID).

Next, FIG. 21 shows the second conventional technique.
From FIG. 27 will be described.

As shown in FIG. 21, the conventional accident simulation device includes a simulated operation panel 4 for monitoring and operating a plant, a plant simulation unit 3 for executing plant simulation processing, and various types of plant simulation units 3. It is composed of an instructor processing unit 2 that makes a request from the plant and an instructor interaction device 1 that executes an interaction with the instructor processing unit 2. The instructor interaction device 1 has a display device 201 and an input device 202. The instructor processing unit 2
Input / output means 203, accident simulation dialogue means 204, accident simulation information
205 and status display means 206. Plant simulation part 3
Has an accident occurrence means 207, an accident simulation means 208, an accident state table 209, an execution state monitoring means 210, a plant characteristic calculation section 211, and a simulated operation panel I / F means 212.

When an accident simulation is performed with the above configuration, FIG.
The accident simulation execution screen is used to set what kind of accident simulation is to be performed through the accident simulation dialogue means 204.

For example, when requesting an accident simulation that a recirculation controller of a nuclear reactor recirculation system of a power plant has failed, designation of the failed controller, rate of change of output signal of the specified controller, and target It is necessary to set values etc. FIG. 22 shows setting items and setting examples. The name of the accident simulation (accident name) and necessary setting item information (information about how to set the setting values 1 to 3) are retrieved and acquired from the accident simulation information 205 in FIG. In the example of number 3 in FIG. 22, the selection item “recirculation controller failure” (name of accident simulation), setting value 1 “main controller” (selection of failed controller), setting value 2 “60%” ( This is a case where the setting is performed such as the target value of the output signal) and the set value 3 “10% / sec” (change rate of the output signal).

In addition to this, conditions for generating an accident simulation and conditions for canceling an accident simulation can be set. In the example of number 3 in FIG. 22, the accident occurrence condition point “generator output” is
When the accident occurrence condition set value becomes larger than "1000MW", an accident simulation occurs, and the accident cancellation condition point "Turbine speed" is canceled when the accident cancellation condition point set value becomes smaller than "1000rpm". ing.

When the execute button is pressed on the accident simulation execution screen of FIG. 26, the accident simulation dialogue means 204 of the instructor processing section 2 causes the accident generation means 207 of the plant simulation section 3 to operate.
Send an accident simulation request 231 to. Upon receipt of the accident simulation request 231, the accident generation means 207 writes the accident simulation setting information 233 set as described above in the accident state table 209, and sends the execution request 232 to the accident simulation means 208. Accident status table 20
In No. 9, the accident simulation setting information 233 is written in the structure as shown in FIG. The accident status table 209 can record a plurality of accident simulations. The accident simulation means 208 performs a simulation calculation based on the accident simulation setting information 233 of the accident state table 209, and outputs the accident simulation value 234 to the plant characteristic calculation unit 21.
1, the plant characteristic is calculated based on the simulated accident value, and the simulated accident is performed through the simulated operation panel I / F means 212.

The accident simulation means 208 is a plant characteristic calculation unit.
When sending the accident simulated value 234 to 211, processing as shown in FIG. 24 is performed. When the execution request is made, the accident simulation means 208 reads the accident simulation setting information 233 of the accident state table 209. First, it is checked whether the occurrence condition is set, and if it is set, a check is performed until the condition is satisfied, and after the occurrence condition is satisfied, an accident simulation is executed. If there are no conditions for occurrence, an accident simulation will be conducted immediately. Next, it is checked whether the release condition is set and checked until the condition is satisfied, and after the release condition is satisfied, the accident simulation is finished.

Explaining the number 3 in FIG. 22 as an example, since the occurrence condition is set in this accident simulation setting information, it is checked whether or not the accident occurrence condition point generator output is larger than 1000 MW. The current value of the generator output is acquired from the plant characteristic calculation unit 211 in FIG. The obtained current value is 10
If it is less than 00 MW, the accident simulation waits for the occurrence condition to be satisfied, and continues to acquire the current value until it exceeds 1000 MW. When the current value is larger than 1000 MW and the condition is satisfied, the simulated calculation is performed according to the values set in the set values 1 to 3 (the output signal of the main controller approaches 10% per second toward the target value 60%). The accident simulation value 234 is sent to the plant characteristic calculation unit 211, and the accident simulation is started. After executing the accident simulation, check the cancellation conditions. Number 3 in FIG. 22
Then the current value of the turbine speed of the accident release condition pointer is
Since it is set to cancel when the speed becomes lower than 1000 rpm, the accident simulation waits until the cancellation condition is satisfied until the current value of the turbine speed becomes lower than 1000 rpm. When the current value is less than 1000 rpm and the condition is satisfied, the simulation calculation ends and the accident simulation ends.

After the accident simulation is completed, the accident simulation means 208 erases the completed accident simulation setting information in the accident state table 209.

The executed accident simulation state is displayed as a list on the accident simulation state display screen of FIG. When displaying
The accident simulation setting information is acquired from the accident status table 209 via the status display unit 206, and the accident simulation is performed by changing the color such that those under execution and release conditions are red, those for timing are yellow green. The states are displayed so that they can be distinguished. Whether it is being executed or is waiting for the occurrence condition to be satisfied is determined by the status display means 206 from the execution status monitoring means 21.
The execution state monitoring request 236 is sent to 0, and the execution state monitoring means 21
Judgment is made based on the accident simulation status data 237 sent from 0. The check of the accident simulation state is periodically performed, and when the state changes, the color of the accident simulation setting information displayed in the list is changed immediately.

Further, in order to newly make an accident simulation request 231 and display the accident simulation setting information in the list, or to delete the accident simulation setting information from the list when the accident simulation is completed, the failure state table 209 is checked. Is also done periodically. If new accident simulation setting information is added to the failure state table 209, it is determined that a new accident simulation has been executed, and the accident simulation setting information is acquired from the accident state table 209 and sent from the execution state monitoring means 210. The state is judged based on the incoming accident simulated state data 237, and the list is displayed in the color suitable for the state. If the accident simulation setting information that was previously saved is deleted from the accident state table 209, it is considered that the accident simulation has ended and is deleted from the list display.

As described above, in the state when the accident simulation is performed, as shown in FIG. 25, the state transitions such as waiting for the occurrence condition to be established, the accident simulation being performed, and the accident simulation being extinguished have been made by the execution request of the accident simulation.

Next, FIG. 28 shows the third conventional technique.
Starting from FIG. 32, description will be made.

The scheduling function of the conventional plant simulator will be described with reference to FIG. The scheduling function of the conventional plant simulation device includes a simulation operation panel 4 that monitors and operates the plant, a plant simulation unit 3 that executes plant simulation processing, and an instructor that requests the plant simulation unit 3 for various plants. A processing unit 2,
The instructor interaction device 1 executes an interaction with the instructor processing unit 2. A display device 301 and an input device 302 are configured in the instructor dialogue device. The instructor processing unit 2 includes an input / output unit 303,

The scenario execution management means 308 is configured. The plant simulator 3 includes an accident simulator 309, an accident state table 310, a plant characteristic calculator 311 and a simulated operation panel I / F.
Means 316 are configured.

When executing an accident simulation scenario with the above configuration, the scenario creating means 304 first creates an accident schedule as a scenario file 306 in accordance with the training scenario. Multiple scenario files 306 can be created.
6 is selected. Figure 29 shows the structure of the scenario file 306.
It shows in (A). Multiple accidents can be set in the scenario file 306. The scenario file creation method is shown in FIG. 30 and FIG.
1 and FIG. 32. First, when the creation scenario file No is selected on the screen of FIG. 30 and the edit button is pressed, the screen of FIG. 31 is displayed. Here, when the accident number to be registered is selected and registered (the registration button is pressed), the screen of FIG. 32 is displayed. Here, the accident name, set values (target value, rate of change, etc.) and, if necessary, occurrence / cancellation conditions are set. In this example, the accident name "recirculation controller failure", setting value 1 "main controller" (designation of the controller that fails), setting value 2 "60%" (output signal target value), setting value 3 " 10% / sec ”(rate of change of output signal).

When executing the scenario file 306, first, the scenario file 306 is selected from the screen example of FIG. 30 via the input / output means 303 to request registration, and the scenario execution dialogue means 305 causes the necessary scenario file 306 to be created. To the scenario execution file 307. At this point, the scenario execution file 307 is in a standby state. When the scenario execution file 307 is executed, the scenario execution file 307 registered in advance is selected from the screen example of FIG. 30 to make an execution request, and the scenario execution management means 308 is sent to the scenario execution management means 308 via the scenario execution dialogue means 305. Send a wait release request.
The scenario execution management means 308 that has received the standby release request writes the setting contents of the specified scenario execution file 307 in the accident status table 310, and issues the execution request to the accident simulation means 30.
Send to 9. The structure of the accident status table 310 is shown in FIG.
It is possible to save multiple scenario files. The accident simulation means 309 reads the accident occurrence condition from the accident state table 310 and waits until the condition is satisfied. If no occurrence condition is set, it is executed immediately. Accident status table if execution conditions are met
If there is a change rate based on the setting contents of 310, the accident state is calculated, and the simulated accident value is sent to the plant characteristic calculation unit 311 to simulate the accident. If the accident release condition is set, release after the release condition is satisfied. When it is desired to cancel the accident currently being executed, the scenario execution dialogue means 305 sends a cancellation request to the scenario execution management means 308. The scenario execution management means 308 that has received the cancellation request sends the cancellation request to the accident simulation means 309. Upon receiving the cancellation request, the accident simulation means 309 immediately cancels.

After the accident simulation is finished, the accident simulation means 309 erases the set contents of the completed accident simulation in the accident state table 310.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an example of the plant simulator of the present invention, a fault simulation of the plant simulator will be described with reference to FIGS.
Will be explained.

FIG. 1 is a diagram showing the construction of a plant operation training simulator apparatus which is an embodiment of a plant simulation apparatus. In FIG. 1, 101 is a display device, 102 is an input device, 103 is an input / output means, 104 is a failure simulation dialogue means, and 105.
Fault simulation generation means, 106 is a failure state storage means, 107 is a simulated operation panel interface means, 108 is a plant characteristic calculation unit, and 109 is an ID conversion database.

In the plant simulator of this embodiment, an ID conversion database 109 is newly provided. As shown in FIG. 2, the ID conversion database 109 has a configuration in which the failure type, the PID, and the failure state can correspond to each operating end. The failure state is classified into a case where the failure state is determined by the type of failure and a case where it is necessary to input an analog value failure state or a digital failure state from the instructor dialogue apparatus 1.

FIG. 3 is a failure state setting screen, and is an example of a drawing for prompting the instructor to select an operating end to be simulated and a failure type.

The instructor first sets the operating end name and then sets the failure type related to the operating end. The menu on the screen displays a list of simulated operation ends and a list of failure types, and the operation ends and the failure types can be selected from the list. In the setting screen shown in FIG. 3, "main steam stop valve" is selected in the operation end list menu, and "actuator direction failure" is selected in the failure type list menu displayed as the failure type related to this operation end. It represents the state.

Information on the operating end and the failure type set by the failure state setting screen of FIG. 3 is transferred from the instructor dialogue apparatus 1 to the failure simulation dialogue means 10 via the input / output means 103.
Input to 4. Next, the failure simulation dialogue means 104 uses the ID conversion database 109 of FIG. 2 to convert the corresponding PID into the corresponding PID according to the operating end and the failure type, and the failure simulation generation means 10
Output to 5.

The fault simulation generating means 105 rewrites information in the fault state storage section 106 as in the prior art. Since the input data of the fault simulation generation means 105 has the same PID as that of the conventional technique, the fault simulation will be performed thereafter by the same method as the conventional technique.

By the above method, the instructor is
It is possible to simulate a plant failure without knowing the ID.

Next, as a second embodiment of the plant simulator of the present invention, the accident simulation registration function of the plant simulator will be described with reference to FIGS. 4, 5, 6, 7 and 8.

FIG. 4 is a diagram showing the construction of the plant simulation device of this embodiment, FIG. 5 is a diagram showing an accident simulation registration table, and FIG. 6 is a state transition diagram for accident simulation. FIG. 7 is a diagram showing an accident simulation execution screen, and FIG. 8 is a diagram showing an accident simulation state display screen.

As shown in FIG. 4, the plant simulation device of this embodiment comprises a display device 201, an input device 202, and an input / output means 203.
, Accident simulation dialogue means 204, accident simulation information 205, status display means 206, accident occurrence means 207, accident simulation means 208, accident status table 209, execution status monitoring means 210, plant characteristic calculation unit 211, simulated operation panel interface means 212 ,
It is composed of an accident simulation setting registration table 213.
In this embodiment, an accident simulation setting registration table for storing accident simulation information is newly provided. The accident simulation that has been set on the accident simulation execution screen shown in FIG. 7 is stored in the accident simulation setting registration table 213 as the accident simulation setting registration information 240.

When executing an accident simulation with such a configuration, when the execution button is turned on in the accident simulation execution screen, the accident simulation dialogue means 204 issues an accident simulation request to the accident occurrence means 207. The accident generating means 207 receives the accident simulation setting information 240 from the accident simulation setting registration table 213 and writes the accident simulation information 233 in the accident state table 209. Further, the execution request 232 is sent to the accident simulation means 208. The accident simulation unit 208 executes a simulation calculation based on the accident simulation setting information, sends the accident simulation value 234 to the plant characteristic calculation unit 211, calculates the plant characteristic, and transmits it via the simulated operation panel interface 212. Send to the simulated operation panel 4 and execute the accident simulation.

The accident simulation execution screen shown in FIG. 7 and FIG.
The accident simulation state display screen shown in Fig. 26 has a configuration in which a registration button is added to the accident simulation execution screen of Fig. 26, and an execution button and a delete button are added to the accident simulation state display screen of Fig. 27.

The structure of the accident simulation setting registration table 213 is shown in FIG. This information table has a form in which request status information is added to the accident state table shown in FIG.
This request status stores information on whether it is a registration request or an execution request.

In this embodiment, as shown in FIG. 6, a standby state is added to the state transition of the accident simulation shown in FIG. 25, and a change is made so that the disappearance state of the accident simulation due to the release condition is not performed. In this way, by registering the setting contents and having the accident simulation in the standby state, the released accident simulation can be returned to the standby state again and can be re-executed.

Further, by adding the standby state of the fault simulation, the accident simulation state display screen of FIG. 8 shows three states, that is, the accident simulation being executed, the fault simulation waiting for the occurrence condition to be satisfied, and the standby state fault simulation. Since they exist, they are displayed separately in red, yellow green, and blue. Accident simulation information is acquired from the accident simulation setting registration table 213, and whether it is registered or being executed is acquired from the request status of the accident simulation setting registration table 213, and is it waiting for the occurrence condition to be met or being executed (waiting for the cancellation condition to be met)? Determines from the simulated accident state data 237 sent from the execution state monitoring means 210.

When the accident simulation disappears, the list display is changed from red to blue and the request status of the accident simulation setting registration table 213 is set from execution to registration. In order to set from execution to registration, the status display dialogue means 206 checks whether there is accident simulation information deleted from the accident status table 209, and if it has been deleted, the accident simulation information list is colored and requested. Rewrite the status from running to registered.
When an execution request is made to the accident simulation in the registered state, the list display is changed from blue to red or yellow-green, and the request status of the accident simulation setting registration table 213 is set from registration to execution.

When the accident simulation setting registration table 213 is registered, it is saved unless a deletion request is made. Therefore, even if the accident simulation is erased, the setting contents remain saved.

The acquisition of the accident simulation information, the acquisition of the execution status, and the check of the accident simulation deletion are all carried out periodically, and the state display screen suitable for the accident simulation situation is displayed.

In the conventional plant simulator, the accident simulation execution request cannot be made from the accident simulation status display screen shown in FIG. 27. However, the present invention enables the accident simulation execution request in the registered state to be made. In addition, the accident simulation information of the accident simulation for which the accident simulation is completed (the cancellation condition is satisfied) is not deleted, but is saved by putting it in a standby state. When deleting the accident simulation information, the accident simulation setting registration information in the accident simulation setting registration table 213 is deleted and the accident simulation setting registration information in the list display is deleted by the delete button in the accident simulation state display screen FIG.

As described above, by saving the accident simulation information of the accident simulation, the frequently used accident simulations and the ones to be executed immediately are registered, and the accident simulation state display screen shown in FIG. Accident simulation can be executed instantly by simply selecting from the list display and pressing the execute button.
