Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a plant simulating device such as a power generation operation training simulator, and particularly to a plant simulating device such as a power generation operation training simulator, and particularly to a system for simulating a failure of operation display equipment of a power generation plant and a change in plant status. The present invention relates to a plant simulator that can reduce the burden on instructors.

[Technical background of the invention and its problems] Operation training for power generation plants is based on clear operating procedures based on operation patterns depending on the plant status, but in recent years, with the increase in energy demand, capacity has increased, In addition, as energy conservation is progressing, plant operating methods are also becoming more complex.

In order to operate such power plants safely and efficiently, it is important to train operators with advanced operating techniques. By simulating failures of plant operation equipment and changes in plant status (hereinafter referred to as alterations), trainees are trained to analyze and recognize the effects of accidents and the characteristics of equipment, and learn appropriate operating procedures. For this reason, alteration training has become an important curriculum.

Alteration in conventional driving training simulators is classified by power plant system, such as turbine system, generator system, and water supply system, as a means of searching for the identification name of the equipment or plant status value for which alternation is to occur. equipment or plant status values that are suitable for changing the plant status from the materials or lists listed.
& Search for the 3A5J name for each system, or use a computer to display a list of equipment or plant status values and identification names for each system on a CRT display, and check the alternation name. I searched for the identification name by turning the display and watching the page until I found the equipment or plant status value I wanted.

Promoting training based on such materials is very time-consuming and requires a lot of time even when a list of a huge variety of identification names is displayed on a CRT display, just searching for the identification name.

Also, it is important for the operation side to check how the status values of the equipment or plant that have undergone alternation are affected in the power generation plant, but as a method of checking, Check the input/output side plant status of the equipment or plant status value on the simulated operation panel, or search for the identification name of the input/output side plant status value on the CRT display using the above procedure. This was an inefficient operation in which the current value was displayed one by one.

The power generation operation training simulator is of course used for normal start-up/shutdown operation training, but it is also used for training to develop operators' ability to make quick decisions and take appropriate measures in the event of an accident at a power generation plant. It is meaningful to do this, and for this reason, instructors need to give instructions promptly.

[Objective of the Invention] The present invention has been made in view of the above-mentioned circumstances, and is intended to enable easy alteration from a plant system diagram or logic sequence even if one does not remember the identification name to be replaced, and to facilitate implementation. It is an object of the present invention to provide a plant simulation device that enables M transfer training closely related to plant operation and improves instructors' teaching efficiency.

[Summary of the Invention] The present invention reduces the burden on the instructor by displaying a plant system diagram or logic sequence diagram on a screen display device so that the instructor can input instructions for the system whose status is to be changed from the touch screen. .

[Embodiments of the invention] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of one embodiment of this paper. In order to perform alteration, the instructor selects an alteration item from the function menu list displayed on the CRT display device 10 by directly touching the touch screen 11 with his or her hand.
The CRT uses the operation signal a from the CRT as the operation request signal.
Interrupt the dialogue processing unit 20.

Thereby, in response to the alternation request signal, the CRT interaction processing section 20 displays a list of alternation items for each system from the plant system display storage section 30 on the CRT display device 10 through the display signal to the CRT.

Next, the instructor inputs the alternation items for each system from the touch screen 11 to the CRT dialogue processing unit 20 as the operation signal a from the CRT, and the CRT dialogue processing unit 20 inputs the alternation items for each system based on the The plant system diagram or logic sequence display data is retrieved from the plant system display storage unit 30, the identification name and unit for the table data are retrieved from the plant status identification name storage unit 31, and the plant simulation calculation unit The current plant state value is read from 50 and displayed on the CIT display device 10 through the display signal to the CRT along with the previous plant system diagram or logic sequence.This current plant state value is displayed on the CIT display device 10. During this time, the CRT dialog processing section 20 reads the information from the plant simulation calculation section 50 and displays it on the CRT display device 10.

Here, the plant system diagram or logic sequence based on alternation items for each system is a plant state value operated by alternation, such as starting/stopping of valves, pumps, etc., or changing the state of plant state variables such as flow rate and temperature. There are some related to logic sequences such as relay sequences and limit switches such as sensors, so by selecting alternation items for each system, a plant state diagram that is easy to alteration is automatically displayed.

FIG. 2 is a display example of a display screen when a plant system diagram is displayed on the CRT display device IO by inputting system-specific alternation items from the touch screen 1.1. The CRT display screen of this plant system diagram has a plant system display section that displays the plant system, displays alteration information necessary for alteration, and allows alteration operation by directly touching the touch screen. It consists of an alternation operation section.

The plant system display section shows plant equipment pumps PA, Pa
, -=, PD, valves Va, Vb, -, Vh, heat exchanger C, heater 11, etc. are made to correspond to the actual plant, and plant status inputs Ia, Ib, ..., Id, plant status outputs Oa, Interlocks with other plant systems are displayed graphically using Ob and Oc, and the status of plant equipment can be displayed by changing colors depending on the start/stop or 0N10FF status, or by converting the status value of the equipment into an easy-to-understand unit. express. In addition, the plant state values Pa, Pb, obtained by each plant equipment
..., Pi also converts the state quantity into a unit that matches the plant state value and displays it.6 The alternation operation section changes the identification name of the plant equipment, plant state value, and alternation as alternation information. You can change the alteration by directly touching the touch panel 11 and the message display area N that displays the change value you are trying to change, the unit of the status value, an error message for an incorrect alteration operation, a message prompting you to re-enter, etc. Control signals “0PEN”, “CLO5E” and alternator that can change the state value
The control signal consists of an operation signal "εXC" that activates the version execution process.

The instructor can specify the position of the device or alternation status value to be altered on the displayed plant system diagram or logic sequence by touching the position of the device or alternation status value. By operating "0PEN" and "CLO5E", for example, if you want to set a valve that is fully open to fully open, specify the valve on the displayed plant system diagram and change the control signal of the control signal. CLOS
The set value can be fully opened by touching ``E''.

As described above, alternation requests can be made on the plant system diagram or logic sequence.
The alternation request is completed by touching "EXC" on the touch screen II.

The manner in which the requested alternation is generated in this manner will now be described.

The CRT dialogue processing section 20 transmits the identification name and setting value to the alternator.
output to the version execution unit 40. The alternation execution unit 40 changes the value to a value that can be calculated by the plant simulation calculation unit 50 based on the contents of the identification name and set value, and sends it to the plant simulation calculation unit 50. The plant simulation calculation unit 50 is the core of the power generation operation training simulator, and receives operation input signals d from the simulated operation panels such as operation switches and setting devices installed on the simulated operation panel 60 operated by the trainee. , a power generation plant is simulated in order to adapt to the operations of the trainees, and the calculation results are displayed on the simulated operation panel using output C, which displays lamps on the simulated operation panel, drives instruments, outputs from recorders, etc. .

Therefore, based on the alternation information sent from the alternation execution section 40, the plant simulation calculation section 50 calculates the state of the power generation plant commensurate with the alternation information, and outputs the result as a display output to simulate the operation. Board 6
Output to 0.

FIG. 3 is a flowchart showing part of the functions of the CRT interaction processing section 20. As shown in FIG.

The execution of the alternation is started when the instructor selects an alternation item from the instructor function list on the touch screen 11.

CRT display device i! ! io and CRT interaction processing section 20,
Interactive processing is performed via the CRT's operation signal a and the display signal to the CRT, and the instructor inputs alternation items for each system, thereby displaying the CRT display device 1.
0 starts the operation of the illustrated flowchart when the plant system diagram for the alternation items for each system is displayed.

Block 21 is a process in which the instructor selects the equipment or plant state on which alternation conversion is to be performed. In this case, the equipment or plant status of the plant system diagram is displayed on the CRT display device 10 from the plant simulation calculation section 50 based on the respective identification name, and the current value of the plant status value is displayed on the CRT display device 10 through the CRT dialog processing section 20. , it is possible to select an alternator by referring to this display state.

In block 22, the validity of the alternation item selected by the instructor is determined, and if it is invalid, block 27
An error message is created and displayed on the CRT display device 10 along with the display signal to the CRT to prompt the instructor to re-enter the message.

If the equipment or plant status item selected by the instructor is valid, in block 23 the identification name, current value, and unit of the equipment or plant status item are displayed on the CRT display lO.
to be displayed.

Block 24 is a process in which the instructor sets plant status values for equipment or plant status items.

Setting of this plant status value is done by using the control signal '0PEN'('ON') or 'CLO' on the touch screen 11.
Setting values can be set by touching 5E"("OFF"), and setting values with intermediate openings such as valve openings are set using the control signal "0PEN"('"ON") and "CLO".
By continuing to touch 5E"("OFF"), the plant status value is increased or decreased from the current value to determine the set value.

Block 25 is a process of waiting for input of an alternation operation signal by the instructor, and if an alternation execution signal is not input from touch screen 11, the process does not proceed to the next block.

If the alternation execution signal is input, the process moves to block 26, where the identification name and setting values created through the interaction between the CRT interaction processing section 20 and the CRT display device are output to the alternation execution section 40.

[Effects of the Invention] As explained above, according to the present invention, when an alternation occurs, there is no need for the instructor to search for the identification names etc. of system 2 equipment one by one, and the instructor can use the displayed plant system diagram or Since the generation operation can be easily performed from the logic sequence, it is possible to minimize confirmation of erroneous alteration inputs, etc. Moreover, the operation is simple and the movement of the plant can be easily grasped, making training easier. Efficiency can be improved.
