In particular, the present invention relates to an operation training support system that includes a training support calculation device that evaluates whether or not the driving operation of a trainee No. J5 is appropriate during plant operation training and compiles the evaluation results into a database.

(Prior Art) Generally, plant operators who operate plants such as nuclear power plants, thermal power generation Plan I, or chemical blunts learn plant operating methods through a training plant simulator.

In particular, in recent years, as the operational efficiency of G1 actual nuclear power plants has improved, opportunities to operate actual plants have decreased, and experiential learning using plant simulators has become increasingly important.

Training of plant operation techniques for blunt operators using such a plant simulator is carried out, for example, with a team of four trainees and one or two instructors, assuming various necessary events.

In other words, the instructor operates various operating tools on the instructor console to cause various events such as turbine generator trips, reactor scrams, and accident V5 to occur in the simulated plant as appropriate, and to develop appropriate operating methods in response to these various events. By actually operating a simulated central control panel, trainees can gain hands-on experience in driving techniques for four melons.

In addition, the instructor can give appropriate advice and instructions regarding the driving method if the operation procedure is clear, such as normal start-up and stop operations, and the amount of operation per unit time is relatively small.

(Problems that the invention attempts to solve) However, for example, in the case of 11N, where a field lightning such as a nuclear reactor scram or an accident occurs, the operation method of Plan 1- in that case is relatively complicated, and moreover, the unit time Successful operation ω
Since a plurality of trainees in one team often perform a plurality of operations under psychological stress, there is a problem in that there is a limit to how a small number of instructors can properly instruct each of these trainees.

In addition, in case of an emergency, there is a limit to the ability of the instructor to point out whether the series of operations performed by the trainee on the simulated central control panel are appropriate operations according to the state of the simulated plan l-.

Therefore, the present invention has been made in consideration of the above circumstances.
It automatically evaluates whether the trainee's operation is appropriate according to the plant status at that time, displays the evaluation results, manages the evaluation results in a database, and edits the data contents. The purpose is to provide a driving training support device that can display the following information at any time.

(Example) Hereinafter, an example of the present invention will be explained with reference to FIGS. 1 and 2.

FIG. 1 shows the overall configuration of an embodiment of a general plant simulator A and a driving training support device B according to the present invention. First, to explain about the blunt simulator, in FIG. A simulated central control panel 3 and an instructor console 4 are organically connected via a cable 2.

v! Pseudo central control tll13 is the central &1J I of the real plant
ll It is arranged in an almost hook shape in the simulated central control room 5, which simulates the palm of the hand.

There will be one trainee for plant operation at the main 5133A in the hook-shaped corner of the simulated central system 0 [1! One or two instructors are placed on the instructor console 4, which is placed further behind the head desk 3C.

The simulated central control TLL board 3 remotely controls the operation of the simulated plant 1. Various switches, handles, parts, and other operating tools for Il, various J1 instruments that indicate the plant status of the simulated plant 1, display devices such as indicator lamps and CRTs, various annunciators (alarms), etc. are arranged. When the operating tools of the central control panel 3 are operated, the operating signal is given to the simulated plant 1-1 through the signal cable 2, and the simulated plant 1 receives the necessary electrical signals so that it exhibits the same behavior and reaction as the actual plant. is fed back to the simulated central control panel 3.

Mock plant 1 is a simulated central system fil! ! '! (The main storage device 1A stores the operation positions of all the operation tools of 3 and the alarm states of all the annunciators, and the main storage device 1A stores the operation positions of all the operation tools of the 8N pseudo central control panel 3.) It has a calculation CV device 1B which calculates the plant parameters of the plant 1 to values almost similar to those of the actual plant and feeds back the plan me parameters to the simulated central control!'133 as plant data indicating the plant state.

The instructor console 4 is in the shape of a simulated central control room 5.
It is configured such that the occurrence and shutdown of various events such as A-stage setting reactor scram or generator trip can be set in the simulated plant 1, and the simulated plant 1 is configured to maintain the plant state set by the instructor console 4. In this situation, the plant parameters are fed back to the simulated central control board 3 by calculating the changes in the plan (parameters) by the trainee's operations in the simulated central control system 13 using the calculation device 1B.

Next, the driving training support device B according to the present invention will be explained.

This operation training support device B evaluates whether the operation of the operating tools of the simulated central control I panel 3 performed by the trainee is appropriate in light of the plant state of the simulated plant 1. At the same time, the evaluation results will be compiled into a database.Then, by managing this data, driving quality will be improved.
The error trends and weaknesses that are easy to fall into are clarified, and it provides a means to take countermeasures in that respect, and furthermore, it provides decision materials for advancing training to higher alpha content. configured.

That is, the driving training support device 1ffB includes a data collection device 7, a data storage device 8, a training support calculation device 9, and an input/output device 10.

The data collection device 7 collects various data stored in the main storage device 1A of the simulated plant 1, such as detective data indicating the operating positions of all operating tools of the simulated central system DHf3, and presence or absence of annunciator alarm (r3, etc.). , indicating the plant state of the simulated plant 1, such as reactor water level, reactor pressure,
The plant parameters of the pump motor, etc. are read in, and each of these data is stored in the data storage device 8 in chronological order as training data.

The training support 11 performance Q determination device 9 forms the core of the driving training support v4 system according to the present invention, reads the old and new training data stored in the data storage device 8, compares it with lυ, and determines the content of the data. If there is a change, it is interpreted as a change in the situation, and an error analysis of the training operation content is performed based on the new training data. 1. During error analysis, the following are determined: (1) Whether the necessary operation is appropriate or not. (2) Whether the selection of the operating device was correct and the procedure was correct.

FIG. 2 is a flowchart showing how to handle the reactor mode switch as an example of error determination. The mode switch of a nuclear reactor has four positions: stop, refuel, start, and run, and it is necessary to use these four positions depending on the situation in order to disable the interlock.

The driver's appearance outlines the following: confirming the reactor scram, controlling the water level of the original T reactor, and switching the reactor mode switch to shutdown. A high degree of specialized knowledge is required to determine an error, and the 70-diaert shown in FIG. 2 is the result of incorporating the knowledge of a driving expert into the operating procedure manual and developing the determination.

The decision-making process requires a high level of knowledge, taking into account not only the timing of operations, but also parameters such as the opening/closing status of the main steam isolation valve (MSIV) and changes in main steam pipe pressure.

For example, error P1, indicated by symbol E in FIG. 2, is determined simply by the selection of the mode switch, and is derived when the mode switch is set to Refuel or Stop.

Also, error P2. Both P3 are determined based on the change in main steam pipe pressure, and are derived when the main steam pipe pressure is low. Furthermore, the error P4 is determined based on the elapsed time after the scrum, and is derived when two minutes have passed after the scrum.

Further, the training support operation equipment 9 evaluates the details of the operator's operations and creates a database of the evaluation results based on the error determination results derived in this way, and provides materials for effectively implementing training. The evaluation of the operation contents of driving fl is as follows.
For example, by setting an evaluation index in advance for each item that causes an error as shown in FIG. 2, the evaluation is automatically performed based on the details of the operator's error. Roughly speaking, checkpoints can be set in advance for important operations, and depending on whether or not the training has passed these checkpoints, guidance can be given as to whether to proceed to the next stage of the training or whether to further strengthen the training with the same content. It is possible.

A database of evaluation results is constructed in order to manage data specific to each operator, and to edit and output the contents upon request from the instructor. for example,
At the request of the instructor, past error data for a certain operation by a certain operator may be displayed, and various other data editing operations may be performed.

The input/output device 10 includes, for example, a CRT and a keyboard, and operates the -V-board to output the evaluation results of the operation contents from the training support control device 9 to the CRT and display them on the screen. Furthermore, an instructor or the like operates a keyboard to input various requests regarding database operation, edits data contents, and displays the edited data contents on the CRT.
