In the figure, 11 is an operation training support device, and 12 is a data collection unit that collects plant state data, plant operation data, and selection data of a screen to be monitored. A plant data collection unit 13 collects plant status data from the simulator computer 1 and plant operation data from the operation monitoring panel 2. A screen selection data collection unit 14 collects selection data of a screen monitored by the operation monitoring panel 2.
[0003]
Reference numeral 15 denotes an abnormal location identification unit that identifies the abnormal location of the plant by comparing the status data of the plant collected by the data collection unit 12 with the status data of the plant in a normal state. Reference numeral 16 denotes a screen selection unit that specifies a plant to be monitored based on the identification result of the abnormal point identification unit 15 and selects a screen to be monitored. Reference numeral 17 denotes an accident response screen database in which screens associated with each abnormal location of the plant are registered.
[0004]
An operation procedure selection unit 18 selects an operation procedure of the plant based on the identification result of the abnormal point identification unit 15 and the plant state data collected by the data collection unit 12. Reference numeral 19 denotes an operation procedure database in which operation procedures associated with each abnormal part of the plant are registered.
[0005]
Further, 20 compares the result of selection by the screen selection unit 16 and the operation procedure selection unit 18 with the operation data of the plant collected by the data collection unit 12 and the selection data of the screen to be monitored. It is a training evaluation unit that evaluates the degree of achievement of the driving target. Reference numeral 22 denotes a CRT for displaying the degree of achievement of the driving target evaluated by the training evaluation unit 20.
[0006]
Next, the operation of this conventional technique will be described.
First, the simulator computer 1 simulates an accident or abnormal event of a plant preset by an instructor, and outputs state data of the plant to a plant data collection unit 13 in the data collection unit 12. Then, the trainee monitors the state of the plant simulated by the simulator computer 1 on the operation monitoring panel 2, and in accordance with the state of the plant, controls the operation of the plant and selects the screen to be monitored by the operation monitoring panel 2. Perform using The operation data of the plant by the trainee is transmitted from the operation monitoring panel 2 to the plant data collection section 13 in the data collection section 12, and the screen selection data is transmitted from the operation monitoring panel 2 to the screen selection data collection in the data collection section 12. It is output to the unit 14.
[0007]
Next, the abnormal location identifying unit 15 identifies the abnormal location of the plant by comparing the status data of the plant collected by the plant data collecting unit 13 with the status data of the plant when it is normal.
[0008]
Then, the screen selecting unit 16 specifies a plant to be monitored based on the identification result of the abnormal point identifying unit 15 and selects a screen to be monitored. That is, when the abnormal point identification unit 15 determines that an abnormality has occurred in the pressure of the pressurizer, for example, the pressure of the pressurizer becomes a monitoring target, and the pressurizer pressure monitoring screen is selected. Since the correspondence between each abnormal part of the plant and the screen to be monitored is registered in the accident response screen database 17, the screen selection unit 16 selects the screen to be monitored by referring to the database 17. become.
[0009]
Next, the operation procedure selection unit 18 selects an operation procedure of the plant based on the identification result of the abnormal point identification unit 15 and the plant state data collected by the plant data collection unit 13. That is, when the abnormal point identification unit 15 determines, for example, that a leak has occurred in the bypass pipe, an operation procedure for closing the bypass pipe and opening another pipe is registered in the operation procedure database 19. Therefore, the operation procedure selection unit 18 refers to the operation procedure database 19 to select an operation procedure of the plant as shown in FIG.
That is, valve C is opened, valve D is opened, valve A is closed, and valve B is closed. However, since the valve D may already be open, it is necessary to refer to the state data of the plant at that time. In this case, the operation procedure of the plant is as follows.
Valve C opens → valve A closes → valve B closes.
[0010]
Next, the training evaluation unit 20 compares the selection results of the screen selection unit 16 and the operation procedure selection unit 18 with the operation data of the plant collected by the data collection unit 12 and the selection data of the screen to be monitored. Then, the trainee's degree of achievement of the driving target is evaluated, and the result is displayed on the CRT 22, thereby ending a series of processing of this apparatus. The evaluation is performed, for example, by checking whether the trainee has selected the screen selected by the operation procedure selecting unit 18, that is, by checking whether the trainee has selected the screen selected by the screen selecting unit 16. And comparing it with operation data operated by the trainee to evaluate whether there is an operation error or to compare the timing of screen selection and operation with the timing performed by a skilled operator.
