In FIG. 2, operator training is started (St1). After the start of the training, the operation history and the plant state at that time are stored in the plant state storage area 5 by the state recording unit 4 at a cycle of the specified storage time 7 (for example, 2 minutes) from the state recording unit 4 (St2). . At this time, the state of training can be stored using the instructor console 3 (St2a). The storage of (St2a) is performed by the operator who receives the training by himself / herself in the case of self-learning, and by the instructor when there is a dedicated instructor.

  Next, the operator performs an operation using the man-machine unit 1 according to the simulated state (St3). The plant state monitoring unit 8 constantly monitors the plant state, and the plant state is the storage condition set in advance by the operator or instructor in the specified plant state 9 (for example, feed water flow rate = Wa (300 t / h) in FIG. 3). ) And the plant state (St4), when the storage condition is reached, the plant state monitoring unit 8 issues a storage command, and the state recording unit 4 stores the operation history and the plant state at that time (St6). .

In addition, the plant state within the storage cycle set at the specified storage time 7 is the temporary storage cycle (for example, a 10-second cycle) set in the periodic recording data temporary storage cycle setting unit 11. As a result, the data is temporarily stored in the temporary recording data temporary storage area 12. At this time, the plant state monitoring unit 8 constantly monitors the plant state, and compares the plant state with the storage conditions set in the specified plant state 9 (for example, the feed water flow rate = Wa (300 t / h) in FIG. 6). (St4), when the plant state reaches the storage condition, the plant state monitoring unit 8 issues a storage command, and the state recording unit 4 stores the operation history and the plant state at that time in the plant state storage region 5, Operation history and plant state before the storage time set by the storage interval setting unit 13 (more than the time from the time of operation of the flow control valve to the storage condition, for example, 5 seconds) are temporarily stored between the periodic records. Extracted from the region 12 and stored in the plant state storage region 5 (St6). If not reached, storage is not performed (St5). Further, the data stored in the periodic recording temporary data storage area 12 is discarded when (St2) or (St2a) in the next simulation operation is executed.

  Conventionally, when there is a simulated operation to be watched, it was not possible to return to the simulated operation to be watched, but according to the second embodiment, the plant state after the simulated operation is stored as a storage condition, and Operation history and plant state before the storage time set by the storage interval setting unit 13 (more than the time from the time of operation of the flow control valve to the storage condition, for example, 5 seconds) are temporarily stored between the periodic records. Since it is extracted from the region 12 and stored in the plant state storage region 5, it is possible to automatically return to the plant state immediately before and immediately after the simulation operation is performed.

Further, the state of the plant within the periodical storage is temporarily stored in the periodical recording data temporary storage area 12 at the period set by the periodical recording data temporary storage period setting unit 11 (for example, a period of 10 seconds). To do. At this time, the plant state monitoring unit 8 constantly monitors the state of the plant, and the state change elapsed time measuring unit 31 emits a signal when the time set by the reference time setting unit 32 has been reached. Thus, the plant state monitoring unit 8 compares the storage state (for example, feed water flow rate = Wa (300 t / h)) set in advance by the operator or instructor in the specified plant state unit 9 with the plant state (St44). When the reference time (Ta in FIG. 15) set by the reference time setting unit 32 is not reached, the plant state monitoring unit 8 issues a storage command, and the state recording unit 4 displays the operation history and the plant state at that time. Operation history and plan saved in the periodic recording interval data temporary saving cycle setting unit 11 before the saving interval (for example, 5 seconds) set in the saving interval setting unit 13 To save the state to the plant state save area 5 (ST46). If it has reached (when the operator is performing the correct operation), the storage is not performed (St45).

After the training is started, the state recording unit 4 stores the plant state at that time in the plant state storage region 5 in a cycle of the specified storage time 7 (for example, 2 minutes) (St2). At this time, it is also possible to save the state of training using the instructor console 3 (St2a). The storage of (St2a) is performed by the operator who receives the training by himself / herself in the case of self-learning, and by the instructor when there is a dedicated instructor. Next, the operator performs an operation using the man-machine unit 1 according to the simulated state (St3). At this time, the plant state monitoring unit 8 always monitors the state of the plant, and the plant state monitoring unit 8 is configured so that the plant state and a specific plant state (for example, an operator or an instructor specified in the specified plant state unit 9) The water supply flow rate 300 t / h) is compared with the lower threshold (for example, the water supply flow rate = Wb (290 t / h) in FIG. 29) and the plant state (St94), and when the lower threshold is passed, the plant state monitoring unit 8 issues a storage command, and the state recording unit 4 stores the operation history and the plant state (St96). In addition, a specific operation (flow control valve operation) is performed by the operator at the man-machine unit 1. If the low threshold is not reached, it is not stored (St95). The state change elapsed time measuring unit 31 measures the elapsed time after reaching the low threshold value, and emits a signal at the time when the reference time set by the reference time setting unit 32 has elapsed. With this signal, the plant state monitoring unit 8 When the high threshold is compared with the plant state (St97) and the high threshold (for example, the feed water flow rate = Wa (310 t / h) in FIG. 29) is passed within the reference time (reference time Ta in FIG. 29), The plant state monitoring unit 8 issues a storage command again, and the state recording unit 4 stores the operation history and the plant state (St99).
