Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an operation training support device for supporting the training of plant operators using a plant simulator such as a nuclear power plant. The present invention relates to an operator training support device that can improve the effectiveness of operator training by displaying plant conditions as images in a central control room.

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

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

Training of plant operating techniques for plant operators using such a plant simulator is carried out by, for example, a team of four trainees, one or two instructors, and assuming various contingencies.

The plant simulator has a simulated plant that simulates an actual plant such as a nuclear power plant, and a simulated central control panel that remotely controls the operation of this simulated plant. Trainees operate the various switches and other controls on the panel under the guidance of instructors to operate a simulated plant. Through this, trainees gain hands-on experience in operating the actual plant.

At the same time, the instructor operates various operating tools on the instructor console to cause various events such as turbine generator trips, reactor scrams, and small disasters to occur in the simulated plant as appropriate, and to perform appropriate operation in response to these various events. By having trainees actually operate a simulated Chuo 111 @ board, they can learn advanced driving techniques experientially.

(Problem to be solved by the invention) Nuclear power plant operators are required to undergo advanced training depending on their duties. In other words, novice operators are trained by acquiring basic knowledge about nuclear power, and then acquiring knowledge necessary for plant operation and repeated practical operation training. Also,
Senior operators are also given reinforcement training in areas such as understanding abnormal events, developing management skills, and assessing situations. These trainings include the aforementioned simulator training aimed at maintaining and improving practical skills, advanced judgment, and response abilities, and desk learning aimed at improving a wide range of knowledge about nuclear power and nuclear power plants. It is done.

However, in conventional training, simulator training and desk-based learning are carried out independently, so the knowledge gained through desk-based learning and the operational skills gained through simulator training remain separate, and operators do not acquire them as a whole. . Therefore, both the knowledge gained through desk study and the operational skills gained through simulator training remain at a short-term memorization level, and the training is not effective. In order to solve this problem, it may be possible to maintain a certain level of skill by repeating training more frequently, but such a solution cannot be said to be efficient.

The present invention was developed in consideration of the above circumstances, and integrates knowledge and practical operating skills by displaying the knowledge previously acquired through desk-based learning as an image during operation training using a plant simulator. It is an object of the present invention to provide a driving training support device that can improve the effectiveness of operator training.
