Operators compose computer screens for power plant operation training because they display the numerical values or graphs of dynamic model variables that are executed in the simulator server. Or screen manipulation is not recorded separately.

Accordingly, in the existing simulator system for power plants, when the instructor wants to reset the simulator under certain circumstances, the system variables for the dynamic model can be restored, but how were various computer screens configured at that time? There is a problem in that it is impossible to restore what kind of cruising process has reached the screen at that time.

Even if the information on the computer screens is variable and saved / restored in the same logic as the method of saving / restored the system variables, the screen restoration at the time of restoration may be possible, but at a specific time interval, There is a problem that it is fundamentally impossible to replay how the screen has changed over time as it was in the past.
