Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant sequence simulator device suitable for congestion training and learning training for sequence control in a hydroelectric power plant.

(Conventional technology).

Recently, as thermal and nuclear power plants have become larger in size, many pumped storage power plants have been constructed that utilize surplus electricity to pump up water and use that water to generate electricity during peak load periods. is the mainstream. This pumped storage power generation plant is made up of multiple units and has a large capacity.

In addition, there are many types of operation modes, such as power generation operation, uh water operation, phase adjustment operation, and trial power transmission operation.In addition, each operation mode includes startup control, flow rate control, AFC control, AQn control,
There are a wide variety of control forms, such as independent operation control and program operation control. Moreover, these operation controls are completely automated and the plant is unmanned, with normal operations being carried out by one person from a remote control center.

(Problems to be Solved by the Invention) An operator who operates and manages such a hydroelectric power plant from a distance must not only perform normal operation when the plant is normal, but also perform operations when an abnormality occurs in the plant. During inspections, etc., it is necessary to go to the site and take appropriate measures.

To do so, it is necessary to be familiar with the various control sequences in the various operating modes described above.

Daily training is required. However, current plant simulators for the purpose of operation training are limited to operation training conducted from a remote control center; training for understanding the contents of sequence control, which requires going to the site and operating equipment, is I had no choice but to rely on manual learning.

As a result, the level of understanding was limited, and when the situation actually occurred, there was a problem that it was not possible to quickly and appropriately respond to plant abnormalities.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a plant sequence simulator device that allows trainees to more easily and reliably understand and train the contents of plant control sequences.

[Structure of the Invention] (Means for Solving Problems) The present invention provides a sequence logic simulator section to display a sequence logic diagram on the Cr1T, and to display each condition in the logic diagram as plant control progresses. By sequentially identifying and displaying the establishment of the conditions, the plant control sequence can be grasped, and at the same time, a sequence failure condition setting device is provided to generate sequence congestion, and the establishment of the conditions of the sequence logic diagram displayed on the CRT.

Use a light pen to check if the condition does not hold true.

By confirming that the sequence is not established, it is possible to verify the location of sequence congestion.

(Function) This makes it possible to easily learn the learning and training of understanding plant control sequences and finding sequence congestion points with a sense of realism.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic configuration diagram of a plant sequence simulator device according to an embodiment of the present invention. Plant simulator device 12. Sequence failure condition setting device [
3, CRT4. It is composed of a light pen 5.

In order to create a sense of reality, the simulated control panel 1 has a panel surface similar to the actual machine, including process quantity display meters 11, plant status display lamps 12. A large number of operation switches 13 and the like are arranged. The plant simulator device 2 includes a plant model section 21 that simulates plant conditions and a control device, and a sequence logic simulator section 22 that computes a plant control sequence. Sequence failure condition setting device! !
3 are switches 31, 32, and 33 for setting each failure condition for sequence traffic jam training. ...etc. C
The RT4 is a display device that displays the calculation results of the plant simulator group [2, especially sequence logic diagrams for learning and training of plant sequences, on the screen, and the light pen 5 displays the plant simulator group r! is an input means for interacting with 12.

With the above configuration, when performing sequence learning training to understand plant sequences, trainees operate the plant operation control using the operation switch 13 of the simulated control panel 1 in the same way as in the real machine. @2, the sequence logic simulator section 22 starts calculating the plant control sequence, and the plant status display lamp 12 of the simulated control panel 1 is turned on based on the result. At the same time, the plant model section 21 calculates the plant state based on instructions from the operation switch 13 or the sequence logic simulator section 22, and displays the plant state on the simulated control panel 1 by moving the process amount display meter 11, etc.

In this way, the control sequence of the five plants progresses. At this time, the plant simulator v! The sequence logic simulator section 22 displays a logic diagram of the control sequence at that time on the screen of the CRT 4, and also identifies and displays each time a condition in the logic diagram is satisfied based on the calculation result.

FIG. 2 shows a specific example of this, and shows a sequence logic diagram displayed on the screen of the CRT 4 at the time of automatic start of one power generation. First, the trainees first check the water turbine automatic/manual changeover switch (43-20) installed on the simulated control panel 1.
, AVR automatic-manual changeover switch (43L 90),
Automatic synchronization All automatic/manual changeover switches (43-25) are switched to automatic. Due to this.

The selection switch conditions 41, 42, and 43 are satisfied, and the corresponding lamp displays 41L, 42L, and 43L are turned on.

When the master switch is turned on when this condition is satisfied, the master switch (1) preparation condition 44 is satisfied during the "main engine stop", and the auxiliary equipment starting relay (88X11) is activated. Due to this.

The auxiliary equipment activation condition 45 is satisfied, the lamp display 45L changes to a lit state, and the pressure oil pump (880) and cooling water pump (GAWC) are activated. As a result, auxiliary equipment operating condition 46.41 is satisfied, and lamp displays 46L and 47L turn on. When the oil pressure exceeds the specified value due to operation of the 6-pressure oil pump (88Ω), condition 48 is satisfied and lamp display 48L
changes to lit state. Also, cooling water pump (8811C)
When the cooling water flows through the operation, condition 49 is satisfied.

The lamp display 49L changes to a lit state. Further, if all of the sequence conditions 50 to 53, which are other preparation conditions, are satisfied, the preparation confirmation relay (1x) is activated, and when the 1st condition 54 is satisfied, the lamp display 5 is turned on. Thereafter, in the same way, as the plant control progresses, each time the sequence logic condition is satisfied, the lamp display of the condition displayed on the CRT 4 is sequentially turned on.

Therefore, by observing changes in the CRT-1 screen display and various displays on the simulated control panel 1, the trainee can compare the plant control sequence with changes in the plant status appearing on the simulated control panel 1. In addition, it is possible to grasp and learn dynamically with a sense of realism.

Next, when performing a sequence traffic jam training to determine the sequence traffic jam location, in advance, the failure condition setting switches 31, 32, 33, . . . of the sequence failure condition setting device 3 are used.
・Create a plant control sequence jam by manipulating one of the following. As described above, the trainee operates the operation switch 13 of the simulated control panel 1 to start plant control, and monitors the plant status by looking at the process amount display meter 11 and the plant status display lamp 12. As the plant control progresses, the preset sequence is finally reached.

An abnormal state of the plant appears on the process quantity display meter on the simulated control panel 1 and the plant status display lamp 12. The trainer learns about sequence congestion by observing this situation and assumes the location of sequence congestion. after that.

Check whether this assumed sequence traffic jam location is correct or not.
Check in 4. That is, at this time, the sequence logic diagram as shown in FIG. 3 is displayed on the screen of the CRT 4. However, in this case, all the lamp displays indicating the progress of the sequence when the conditions are satisfied are turned off.

Therefore, the trainer checked the sequence conditions of the sequence logic diagram displayed on the screen of Cl1lT4 using a light pen.
I will check them one by one. In this case, by touching the sequence condition with the light pen 5, if the condition is met, the lamp display will turn on, and one condition will be met.
You can know if it doesn't work. Thereby, it is possible to confirm and verify the cause of the sequence congestion that has been assumed in advance.

In this way, trainees can learn the progress status of plant control sequences by looking at the CRT 4 at the same time as the simulated control panel 1.
The sequence traffic jam set in step 3 can be easily verified by checking using the light pen 5, allowing for realistic and effective training.

Incidentally, the movements of the main equipment of the plant may be displayed simultaneously on the screen of the CRT 4 together with the plant control sequence logic diagram.

[Effects of the Invention] As described above, according to the present invention, it becomes possible to effectively learn plant control sequence learning training and sequence traffic jam training with a sense of realism.
