Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a power plant operation training simulator suitable for initializing a mock board according to the content of power generation plant operation training.

[Technical background of the invention and its problems] In recent years, power generation plants have been made larger in capacity and more energy efficient as energy demand has expanded, and as a result, the operating methods of power generation plants have also become more complex. ing.

In order to operate such power plants safely and efficiently, there is a demand for the training of highly skilled operators, and power plant operation training simulators have been developed to meet this demand.

This power plant operation training simulator is capable of simulating a large number of operation training contents, such as normal plant start-up/shutdown, steady-state operation, as well as safety repair operation assuming all kinds of accidents. With conventional equipment, when initializing the operation switches on the mock board according to the content of the operation training, the initial settings must be performed while referring to the plant operating procedure manual, making the operation complicated and difficult for instructors to perform. There were problems in that it was a heavy burden and led to a decline in training efficiency.

[Object of the Invention] The present invention provides a power plant operation training simulator that allows initial settings of the simulation board according to the selected operation training contents to be extremely easily performed regardless of the state of the simulation board. The purpose is to

[Summary of the Invention] Therefore, the present invention stores in advance the initial state of the mock board corresponding to each driving training content, reads out the initial state of the corresponding mock board when the driving training content is selected, and By comparing the current state of the mock board and displaying only the states of different operation switches on the instructor's display device,
The feature is that the instructor can easily modify the state of the mock board to its initial state.

[Embodiment of the Invention] FIG. 1 is a block diagram showing an embodiment of the present invention, and the power plant operation training simulator of this embodiment has a simulation board 1.
It consists of a board status input device 2, an electronic computer 3, a simulation result output device 4, and a CRT input/output device 5 for instructors.

Similar to the actual control panel, the mock panel 1 has many operation switches,
It consists of a setting device, an indicator, a display, etc., and is configured to enable simulated operation similar to the actual machine.

The board status input device 2 is a device that captures the status of various operation switches, setting devices, etc. of the mock board 1 and inputs it to the computer 3. The simulation result output device 4 inputs the simulation results from the computer 3 to the mock board. It is a device for outputting.

The electronic computer 3 includes a simulated board state manual reading unit 31, an arithmetic control unit 32, a simulation result output unit 33, a simulated content storage unit 34, a simulated board initial state storage unit 35. It has a mock board state change item storage section 36 and a mock board state change indicator 37.

The simulation content storage unit 34 stores a large number of operation training contents, such as starting/stopping the plant, steady operation, operation at the time of an accident, and repair operation performed assuming an accident.

The simulation board initial state storage section 35 stores the initial states of the operation switches of the simulation board 1 for each of the above driving training contents.

The simulated board state change item storage unit 36 stores items of the simulated board 1 such as operation switches for which the initial state of the simulated board 1 of the driving training content set from the instructor CRT input/output device 5 and the current state of the simulated board 1 are different. It is for remembering.

The mock board state change display 37 is for displaying the contents of the mock board state change item storage section 36 on the instructor's CRT input/output device 5.

The instructor's CRT input/output device 5 allows the instructor to instruct the contents of driving training and to record the state of the mock board 1 necessary for driving training.
In the case of this embodiment, the CRT screen displays panel state change items corresponding to the driving training content, that is, items different from the initial state of the mock board 1, on the CRT screen. A list will be displayed.

With the above configuration, the operation of displaying the simulated board state change items on the instructor's CRT input/output device 5 is performed as shown in the flowchart of FIG.

That is, the instructor first sets the desired driving training content through the instructor CRT input/output device 5 (STEP 1).
). This is to import the driving training content in the simulation content storage section 34 and the initial states A, . 5 Input the current state of the mock board 1 in TEP2. This is to input the simulated board states Bi, B2, . . . Bn into the board state input reading section 31 through the board state input device 2. In 5TEP 3, the initial state A□, A2・

Compare the states C, C2, ..., Cn of the simulated board 1 imported into , and if the actual state of the mock board 1 differs from the initial state, change the state change item D1 in 5TEP 4. D...
. . . Dn is stored in the state change storage unit 36, and 5TEP 2
The status items are PID (identification name assigned by plant system and function), PID NAME (description of PID content), TABGET (initial state of mock board for operation training content), CURRENT (state of actual mock board) ,UNIT
(unit representing the state of the state change item) is displayed on the instructor's CRT input/output device 5 in the format shown in FIG. If there is no difference between the actual state of the mock board and the initial state at 5TEP 3, that is, there is no change, it is determined that the items of the mock board 1 that have not changed at 5TEP 6 have been previously stored in the mock board state change item storage unit 36. Determine whether it is true or not.

If it is an item of the stored mock board 1, it is determined that the item of the mock board is an item that has been corrected on the mock board 1 by the instructor. Next, at 5TEP 7, the items stored in the mock board status change storage unit 36 are erased, and at 5TEP 8, the items of the mock board 1 displayed on the instructor's CRT input/output device are erased, and the status is displayed below that item. If there are any items that have changed items displayed, they will be displayed at the top by the items that have just been deleted. This process is for making it easier to see how many status change items are left by modifying the status change items on the mock board by the instructor (compaction of status change items). 5TEP 9 determines whether the mock board state change item is still stored in the mock board state change item storage unit 36, and if the stored state change item on the mock board still remains, 5TEP 2 From 5TEP
This is a procedure for repeating the steps up to 8.

In this way, the instructor's CRT input/output device 5 displays only the state change items that differ from the actual state of the mock board 1 and the initial state, and the instructor can see this and sequentially change the state of the mock board 1 for each state. As the corrections are made, and if they match the initial state, the status change items displayed on the CRT input/output device 5 for staff members will decrease one by one, making it easy to check the status change items and simulate Initialization of board 1 can now be performed easily.

It should be noted that the present invention is not limited to the above-described embodiments; it is possible to output not only to the CRT input/output device for instructors described in the embodiments, but also to an output typewriter for instructors; It is also possible to identify the display of status change items by each display type.

[Effects of the Invention] As described above, according to the present invention, the initial state of the mock board that is set according to the operation training content before the start of plant operation,
Since the state of the mock board that is different from the current state of the mock board is displayed on the instructor's CRT input/output device, the instructor can easily modify the state of the mock board to the initial state, greatly reducing the instructor's workload. This will enable efficient driving training.
