Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is a method for simulating power generation accidents (hereinafter referred to as malfunctions) when conducting 11111 training of power generation plant operations using a power generation operation training simulator. Concerning how to generate.

[Technical background of the invention and its problems]

In recent years, as energy demand has increased, power generation plants have become less crowded and more energy efficient, and as a result, plant operating methods have become more complex. In order to operate such a power generation unit safely and efficiently, it is essential to train operators with advanced operating skills, especially safety 1! Regarding the complicated operation of nuclear couplers that require J, efforts are being made to improve the technical ability of operators, such as by establishing a qualification system.

For starting/stopping a power generation plant, the continuous rotation procedure based on operation/turns depending on the plant status is clear, and moreover, the start/stop process (turns) of actual equipment is performed several times a year. Improving the technical skills of operators regarding startup/shutdown is not a relatively difficult task.However, protective devices to prevent accidents at power plants have also been developed [7-C].
In the unlikely event that an accident occurs, it is essential for operators to make quick and appropriate decisions and take measures with an emphasis on safety. The power generation operation training simulator can of course be used for normal start/stop operation training, but it can also be used to improve operators' quick judgment and appropriate actions in the event of an accident at a power generation plant.
There is great significance in doing things that will save you money.

In other words, 11 using a power generation driving training simulator.
During one training session, the instructor (hereinafter referred to as "instructor") intentionally causes an accident so that the trainees can analyze and recognize the effects of the accident and the characteristics of the equipment, and learn appropriate operating procedures. It is essential.

For this purpose, it is desirable for the malfunction to store all anticipated accidents in advance in the malfunction and the generator for power generation using an electronic computer. Depending on the type, there are generally several hundred
~1000 pieces are available. These malfunctions are classified to be easy for the instructor to select, and are generally classified by power plant system, such as turbine system 1, generator system, and water supply system. Additionally, the malfunction must allow the instructor to freely adjust the severity of the accident. For example, when a main steam pipe is damaged, a small amount of steam leaks from the damaged part, and as the area of damage gradually increases, the amount of leakage increases, but the rate of change in this amount of leakage and the final target value are determined by training. The instructor needs to be able to add or subtract as desired depending on the level.

By the way, one conventional method for generating malfunctions is to use a push button switch installed on a panel called an instructor console that controls a power generation driving training simulator. However, with this method, there must be a one-to-one correspondence between malfunctions and pushbutton switches, and having many malfunctions means an increase in the number of pushbutton switches, and the instructor console Since it is necessary to prepare a very large amount of malfunctions, there is a limit to the amount of malfunctions that can be held.

Furthermore, when simulating the above-mentioned main steam pipe breakage, C1 is limited to a specific rate of change and final purpose, so the instructor cannot arbitrarily adjust the severity of the accident. Therefore, a CRT connected to an electronic computer is used to generate malfunctions. However, in the conventional generation method, as shown below, the instructor receives CRTIi!
Since there is a limit to the number of characters that can be output on the screen, complicated dialogue with a computer must be carried out.

■ Select the system name displayed on the CRT screen. By this selection, a list of malfunction items related to the system is displayed on the CRT screen.

■ The second instructor selects the malfunction item. This selection displays the contents of the information 6- necessary for generating the malfunction. In other words, the necessary information is, in the case of the above-mentioned main steam pipe breakage, an instruction message for inputting the change rate and target value of the leakage amount.

G) The instructor inputs the necessary information from the CRT key date while referring to the instruction message.

■ Check the entered information and press the key switch to generate malfunction.

A malfunction is something that the instructor monitors the plant status and immediately generates when the time comes.If the malfunction occurs at the wrong time, the plant status will change, so it is an effective accident simulation that the instructor can use wisely. I can't do it anymore. However, the above-mentioned dialog operation requires multiple inputs of several digits of information each time a malfunction occurs, and it is also necessary to check whether there is a mistake in the input! Therefore, it will take a lot of time. This makes it impossible to conduct effective driving training at the malfunction occurrence timing e[L.

Therefore, even when generating malfunctions using a CRT, there is a strong demand for a method that allows easy interaction and generates malfunctions immediately.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and its purpose is to provide a method for simulating an accident in a power generation driving training simulator that can generate a malfunction with good response.

[Summary of the invention]

In order to achieve the above object, the present invention stores in a computer the necessary information of the malfunction that the instructor tosses in advance to generate during driving training, and stores the malfunction number stored when the malfunction needs to be generated. It is characterized by inputting only the data to the CRT.

[Embodiments of the invention]

Hereinafter, the present invention will be explained with reference to a dormitory example based on the drawings. FIG. 1 is a block diagram showing an example of the configuration of a power generation driving training simulator according to the present invention. In the figure, the instructor ld destination f malfunction "
When the ``malfunction registration button'' (hereinafter referred to as ``registration button'') installed on the CRT 3 is pressed in order to perform ``registration'', the CRT 9 sends an interrupt signal al and interrupts the computer 2. In response to this interrupt signal AH, the dialog element 2 displays a list of "system names" on the CRT 9 as an output signal. Next, the instructor enters the ``Malfunction 1 registration number'' and ``strain name'' into the CRT3 to register. Press the button. In response to a similar interrupt signal &1, the dialog element 21 reads the nine "registration number" and "strain name" input by the instructor using input signal a2, and outputs a list of malfunction items corresponding to "strain". Display on CRT, 9. When the instructor inputs "one item of the malfunction to be registered" and presses the registration button, the dialog element 21 reads the "item" using the input signal a2 and instructs the content of the input information necessary for the malfunction item. is displayed on the CRT 9 as an output signal. necessary 1
For example, in the case of the malfunction of the main steam pipe breakage mentioned above, the contents of the input information-1 are information such as the rate of change of the leakage amount and the target value. Finally, the instructor inputs the necessary information into the CRT 3 according to the instructions and presses the registration button. The interaction element 21 reads the input signal a2.
input information] and determine its validity.

Woman, each time the above dialogue occurs, the dialogue element 21 determines the validity of the "registration number", "strain name", and one item, and if the input is invalid, the following screen is displayed on the CRT 3. Instead of displaying the message, it outputs an error message to prompt the instructor to re-enter. In this way, if the "registration number", "strain name", "item", and "input information" input by the instructor are all valid, the dialog element 21 excites relay X,
"Registration number", "strain name", "1 item" and "input information" are placed on the storage signal C1 and stored in the storage element 22. When the storage is completed -10=, the dialog element 21 de-energizes the relay X and outputs a completion message as an output signal to the CRTJ.

Next, a method of generating a malfunction registered in this manner will be explained. In order to generate a malfunction, the instructor first presses the malfunction execution button 1 (hereinafter referred to as execution button) installed on the CRT 3. As in the case of registering a malfunction, the CRT 3 An interrupt signal al is sent to the interaction element 21. Accordingly, the dialog element 21 energizes the relay
``Item'' and input information are displayed. Next, the instructor selects the malfunction that he wants to generate from among the malfunctions displayed in CftT3.
Enter the registration number into the CRT3 manually and press the execution button. The dialog element 21 determines the validity of the [registration number], and if it is invalid, returns an error message to the CRT 3, but if it is valid, it excites relay Y and multiplies the 1-registration number signal d. It is output to the function execution element 23.

On the other hand, the malfunction execution element 23 i, i: obtains "1-system name", "E item" and "input information" from the storage element 22 based on "this 1-registration number". The peaks and valleys of are converted into squares that can be calculated by the plant simulation calculation unit 24, and the malfunction output signal f
is sent to the plant simulation calculation section 24. The plant simulation calculation section 24 is the central part of the power generation operation training simulator, and is installed on the simulated operation panel 1 operated by the trainee (7). The display unit 12 displays the lamps on the simulated operation panel Ji, drives the instruments, and outputs the recording needle. Therefore, the Marufon link S/N simulation calculation unit sent from the malfunction execution element 21 calculates the abnormality of the power plant corresponding to the output signal f, and displays the result as a display output. Output to 12.

FIG. 2 shows some of the functions of the above-mentioned interaction elements in the form of a broached diagram, and the functions will be explained using this diagram.

Malfunctions can be registered by the instructor using the CRT.
, :i is started by pressing the registration button located at i. Interaction between the CRT 3 and the interaction element 2I is performed via an interrupt signal a1, an input signal a2, and an output signal S. When the instructor inputs the last input information and presses the registration button, the second The flowchart in the figure starts the operation shown in the figure. Step 51 is for determining whether or not "registration" processing is necessary. In this case, since "registration" processing is necessary, the process moves to step 52. A block 52 judges the validity of the input information inputted by the instructor, and if it is invalid, an error message is sent out in block 55, and an output signal is displayed on the CRT 313- to prompt the instructor to re-input the information. prompt. If the "input information j" input by the instructor is valid, relay X is energized in step 53, and memory element 22 is
Connect to 1. Thereafter, the "registration number", "strain name", "item" and "input information" input by the instructor at Stella 7'54 are stored in the storage element 22 as a storage signal C1. In step 56, it is determined whether or not malfunction execution processing is necessary. In this case, if it is "registration", the "execution" processing is executed.

In step 6), relays X and Y are de-energized,
Detach storage element 22. By the way, the malfunctions that occur during driving training are predetermined according to the level of the trainee, so the above operations can be registered by repeating the necessary number of conversations before starting driving training. be.

During operation training, the trainee operates the controllers and setting devices installed in the operation section 1 to give an operation signal g of -142 to the plan l-simulation calculation section 24, and the plant simulation calculation section 24 In order to calculate changes in the power generation plant in accordance with the operation signal g, turn on or off lamps and alarm indicators on the display unit 12, and drive meters and recorders, output is sent to the display unit 12 as a display output. Output. The trainee constantly monitors the display unit 12 and performs the following appropriate operations to perform a simulated operation of the power plant.

During normal operation under such conditions, when the instructor wants to generate a malfunction, by pressing the execution button installed on the CRT 3, the interaction element 21 beams ~X are excited by the drive signal a1, From the storage element 22, the above-mentioned 111[[r<registered iJ> all malfunctions, ``registration number'', ``strain name'', 1 item'', and 1 input information'' are read out as readout-9-02.

Then, the dialog element 21 outputs the CRT 3 as an output signal.
Display a list of malfunctions registered in .

The instructor sends out the malfunction that he/she wants to generate from among the displayed malfunctions, inputs the "registration number", and presses the execution button. With this operation,
The operation shown in the flowchart of FIG. 2 is started by the drive signal al. In this case, since it is a malfunction "execution" operation, the determination in steps 51 and 56 results in step 57
Processing is performed from Step 57 is to determine whether the "1 registration number" input by the instructor is valid. For example, if the malfunction is not registered,
If the "registration number" is entered incorrectly, an error message will be output in step 6. If the "registration number" is valid, the relay Y is excited in the Stella 7''58, and the memory element 22, malfunction execution element 23, and dialogue element 21
and the malfunction execution element 23, respectively, and drive the element 23 in step 59. With this,
The malfunction execution element 23 receives the “registration number” signal d
As a result, signals e of "system name", "item" and [-input information] are obtained from the storage element 22, and a malfunction output signal f is sent to the plant simulation calculation unit 24 to generate a malfunction. On the other hand, dialogue element 2
1, when the malfunction execution element 23 receives the signal °e from the storage element 22, the relays X and Y are de-energized at Stella 7''61, and together with the storage element 22 and the malfunction execution element 23, The dialogue element 21 and the malfunction execution element 23 are separated.

If we use this method of simulating the accident as described above, there is no limit to the amount of malfunctions we have, and we can register the malfunctions necessary for driving training when we are not conducting driving training. Malfunctions that occur during operation training can be specified by specifying only the "registration number", so checking for incorrect input can be minimized, and furthermore, the operation is simple, so the instructor can easily check the plant as intended. It becomes possible to generate a malfunction in the state.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented with various modifications within the scope of the gist.

- ] 7 - [Effects of the Invention] As explained above, according to the present invention, the necessary information of the malfunction that the instructor attempts to generate during driving training is stored in the computer, and the malfunction occurrence can be detected. Since only the memorized malfunction number is input to the CRT when the need arises, it is possible to provide a highly reliable accident simulation method for power generation operation training simulators that can generate extremely responsive malfunctions. .
