Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant operation training simulation device that simulates plant operation and plant behavior at the time of abnormality for plant operation training.

(Prior art) In various industrial plants such as a nuclear power plant, in order to operate the plant safely and stably, plant operators perform the operation smoothly in normal times and promptly take appropriate measures when an abnormality occurs. Ability to do so is required.

Various operation training simulators for simulating actual plants have been developed for operators of such plants.

As a simulation control function of such a plant operation training simulation device, an initial state setting / save function for setting and saving an initial state of a plant, a replay function for reproducing a plant behavior, and starting or stopping a plant behavior simulated. Start / stop functions are well known.

During the operation training, the instructor (the instructor) performs the operation training by arbitrarily setting the plant state to a state necessary for the trainee using the various functions described above.

By the way, driving training is performed according to a fixed training schedule for each group of trainees. Therefore,
Instructors conducting driving training must be well aware of the training schedule for each trainee group.

(Problems to be Solved by the Invention) However, conventionally, the training schedule of the trainee group was recorded and managed by the instructor. For this reason,
Particularly, when one instructor is in charge of many groups, there is a problem that it takes time to grasp the training schedule of each group.

In addition, since the conventional plant operation training simulation device merely simulates the plant state as described above, during the operation training, it is necessary to understand how the trainees responded at each time when various operations should be performed. , The instructor could not know. For this reason, it was difficult for the instructor to correctly judge the skill acquisition level of each trainee group, and there was a problem that each group could not provide appropriate and effective guidance.

An object of the present invention is to solve the above-mentioned problems, and to provide a plant operation training simulation device in which an instructor can quickly grasp a training schedule and a skill acquisition level of each trainee group and perform appropriate and effective guidance. I do.

[Structure of the Invention] (Means for Solving the Problems) For this purpose, the present invention relates to a member of a trainee group that performs plant operation, the contents and schedule of operation training of each trainee group, In addition to storing the basic correct operation procedures, the operation contents executed by each trainee group are stored at the time of driving training for various operations, and the executed operation contents are compared with the correct operation procedures. The operation contents and the error situation at the time of the operation are determined, and the operation contents and the schedule of each trainee group and the operation contents and the error situation at the operation time in the performed driving training are arbitrarily displayed on the screen as necessary. It is characterized by the following.

(Operation) This allows the instructor to quickly grasp the training schedule and the skill acquisition level of each trainee group, so that appropriate and effective guidance can be provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a plant operation training simulation apparatus according to one embodiment of the present invention. In the figure, an operation switch 1 is provided on a control panel, and a trainee operates a plant. The operation data input means 2 inputs the operation data, and the operation result file 3 stores the operation data. The keyboard 4 is used for inputting a plant state that cannot be set by the operation switch 1 and registration information for the apparatus, and for performing a start operation of each process. The plant state changing means 5 outputs plant state change information according to the input plant state.

The plant dynamic characteristic simulating means 6 simulates a predetermined plant state based on the information stored in the operation result file 3 and the plant state change information from the plant state changing means 5. The process data file 7 stores process data in the simulated plant state. The process data display means 8 displays the plant behavior on a screen of the CRT display device 9 based on the process data.

The member registration means 10 saves information on the trainee input from the keyboard 4 in the member data file 11, and the member display means 12 stores the saved information in a CR.
This is displayed on the T display device 9.

The basic operation / schedule file 13 stores in advance information such as a training execution schedule and a correct operation procedure and operation time of the plant for each training item of each operation training course. The erroneous operation determining means 14 determines the correctness of each of the executed driving operations by comparing the operation procedure information with the information stored in the operation result file 3. The corresponding point determination unit 15 determines whether the driving operation is correct based on a difference between a predetermined operation time indicated in the basic operation / schedule file 13 and a time at which a correct operation is actually performed.

The training progress display means 16 displays a training execution schedule for each training item of the driving training course stored in the basic operation / schedule file 13, the processing results of the erroneous operation determination means 14 and the corresponding time point determination means 15 on a fixed display screen. This is displayed on the CRT display device 9.

The member registration means 10, member data file 11, member display means 12, basic operation / schedule file 13, erroneous operation judgment means 14, corresponding time point judgment 15, and training progress display means 16 surrounded by a dashed line in FIG. This is the part that was not installed in the plant operation training simulator.

FIG. 2 shows the configuration of the storage information stored in the basic operation / schedule file 13 with the above configuration.

By the way, in this embodiment, a plurality of driving training items are scheduled in a certain order, and one driving training course is set.

In the basic operation / schedule file 13, one storage area A is formed corresponding to each such driving training course. To each storage area A, the storage area B _o .about.B _n corresponding to each operation training item is formed. Furthermore, the their respective storage areas B _i, storage area C _o -C _m corresponding to one single driving operation is formed.

In the drawing, “type of driving training course” is type information of the driving training course such as “standard course” and “retraining course”. The “training item” is an operation training item name such as “plant preparation” or “condenser water-filled blow”.

Also, "training scheduled start date and time" and "training scheduled end date and time" of the storage area B _i shows the schedule of the start and end of the corresponding training fields. Each "Operation schedule content" of the storage area C _i represents the operation content such as setting of various switches operated and controlled variables to be executed at the corresponding training fields,
“Scheduled operation time” indicates the time at which the operation should be executed.

Next, when using the plant operation training simulation device of the present embodiment, the instructor first activates the member registration process by a predetermined operation on the keyboard 4.

When the member registration process starts, a member registration screen is displayed on the CRT display device 9 as shown in FIG. 3 (process 101).

FIG. 4 shows this display screen, where display a is the title of the display screen, and display b is "A" for the driving training course type.
4 shows an input unit for inputting characters “〜”. Also,
The display c shows the input part for the trainee's group name, and the display d shows the input part for the name of each member.

The instructor inputs predetermined information to the input sections via the keyboard 4 (process 102).

Each input information is stored and saved in the member data file 11 (process 103), and the CRT display device 9
(Process 104).

FIG. 5 shows the storage information in the member data file 11 stored by the above member registration process. That is, the members data file 11, is formed a storage area D ₀ to D ₁ for each operation training courses, each storage area D _i, the input operation training course type, group name, and full name of each member Is stored.

Thereafter, a prescribed driving training is performed for each trainee group. When performing the driving training, the instructor activates the training progress display process by a predetermined operation of the keyboard 4 when the instructor wants to confirm the training schedule of the training target group.

When the training progress display process is started, the instructor inputs a driving training course and a group name as shown in FIG. 6 (process 201). As a result, the corresponding operation training items and training execution schedules stored in the basic operation / schedule file 13 are read out and read out from the CRT display device 9.
Is displayed (process 202). With this indication, the instructor
It is possible to grasp the training contents to be conducted for the group.

Next, in the above processing, it is determined whether or not there is a training item that has already been performed (processing 203). If there is no training item that has been performed (N in processing 203), this processing ends.

Here, it is assumed that the instructor has implemented a plurality of training items for one trainee group according to the training schedule.

In this driving training, the trainee performs various operations on the operation switch 1 at each time. In this case, the operation results file 3 stores the contents of the operations executed sequentially.

FIG. 7 shows the structure of the storage information stored in the operation result file 3. This storage information is the same as the information configuration in the basic operation / schedule file 13 described above. That is, in the operation record file 3, one by one storage area E for each operation training course is formed, in each storage area E, storage area F _o to F _n corresponding to each operation training item is formed ing. Further, their respective storage areas F _i, the storage area G _o ~G _m is formed corresponding to each driving operation.

And, in each storage area _Fi , "the driving training course type"
Is stored. In addition, each storage area F _i, the actual "training start date and time" and "training items" and "the end of the training date and time"
There are stored, in addition, each storage area G _i, trainee actually perform the "operation content" and "Operation Time" is stored.

If the instructor wants to confirm the training schedule and skill acquisition level of the trainee group after conducting the training for each training item,
The training progress display process is started in the same manner as described above.

As a result, the plant operation training simulation device executes the training progress display process as described above. In this case, there is a training item
In the drawing, Y of process 203), the information of the corresponding storage area B _{i in} the basic operation / schedule file 13 is extracted (process 204), and the information of the corresponding storage area F _i in the operation result file 3 is extracted. Extract (process 205).

Next, the correctness of the driving operation of the trainee is determined as follows based on the information.

That is, if the operation content of the switch operation, the actual operating time T _i indicated by the information stored in the operation record file 3,
When in a certain range of tolerance epsilon _t relative to the operation schedule time t _i indicated by the information stored in the basic operation schedule file 13 determines that the operation is correct.

Further, if the level setting operation, the actual operating time T _i in the same manner as described above is within the range of certain tolerances epsilon _t, and,
The actual set value S indicated by the storage information of the operation result file 3 is a certain allowable error ε _{s based on} the set target value s indicated by the storage information of the basic operation / schedule file 13.
Is within the range, it is determined that the operation is correct.

 Next, a specific example of the erroneous operation determination processing will be described.

FIG. 8 shows an example of the control operation of the pump. The figure (a) shows the rotation speed of the pump, the figure (b) shows the operation of the start switch, the figure (c) shows the set value of the rotation speed, and the figure (d) shows the operation of the stop switch. The state stored in the basic operation / schedule file 13, and the dashed line indicates the actual state stored in the operation result file 3.

In this example, the operation of the start switch is the actual operation time.
Since the T _o is within the range of allowable error ε _t with respect to the operation scheduled time t _o determines that is the correct operation. The setting operation to raise the "500" the number of revolutions from the "100" also, since the actual operation time T ₁ is in the range of allowable error epsilon _t with respect to the operation schedule time t _1, as a correct operation determination I do.

On the other hand, the rotational speed from the "500" setting operation to raise the "1000" is the actual operation time T _2, is in the range of allowable error epsilon _t with respect to the operation scheduled time t _2, the actual indicated by a dashed line set value, so is outside the allowable error epsilon _s with respect to the set target value shown by the solid line is determined to be erroneous. Also, the operation of the stop switch, the actual operation time T ₃ operation scheduled time t ₃
Because outside the range of tolerance epsilon _t respect, that the erroneous operation determining (above, process 206).

Thereafter, the number of erroneous operations for each operation is calculated (step 20).
7), for each training item, the average corresponding time T _AV is calculated based on the actual operation time T _i , the scheduled operation time t _i, and the number of operations n in each operation, (Process 208).

Next, based on the calculated average response time T _AV and the number of erroneous operations, pass / fail of the corresponding training item is determined. This pass / fail determination is performed, for example, when the number of erroneous operations is equal to or less than a certain number,
If the average response time T _AV is within a predetermined time, it is determined based on preset conditions, such as a pass (process 209).

Next, the above judgment results are used together with the training schedule in CR
The screen is displayed on the T display device 9.

FIG. 9 shows an example of the display screen, where display e is the title of the display screen, display f is the training course name, and display g is the group name. The display h is the item number of the training item and the training item name, and the display i corresponding to each item is
A training schedule indicating a training start date and a training end date, a display j is the number of erroneous operations, a display k is the average response time, a display 1 is a standard response time for comparison with the average response time, and a display m is pass / fail. It is a determination result. As the standard response time, for example, the fixed time set for the pass / fail determination of the average response time is displayed.

As described above, according to the present embodiment, the training status and the training schedule of each trainee group and the results of each training item performed are displayed as a training progress display screen on the CRT display device 9 by a predetermined operation. I am trying to. As a result, the instructor can quickly grasp the training status, training schedule and skill acquisition level of the trainee group, so that appropriate and effective guidance can be provided.

In the above embodiment, as the information indicating the results of each trainee group, only the number of erroneous operations, the corresponding time, and the result of the pass / fail are displayed. However, erroneous operations or operation items having a problem with the corresponding time are displayed. You may do so.

[Effects of the Invention] As described above, according to the present invention, the members of the trainee group, the driving training schedule, and the correct operation procedure are respectively stored, and the details of the operation performed during the driving training are stored.
