Description

Virtualization-based customized training system for power plant field operators

[0001] The present invention relates to a power plant training system, and more specifically, to a virtualization-based customized training system for field operators of power plants.

[0002] Operators, the most critical element in the safe operation of nuclear power plants, receive periodic training using simulators capable of simulating various situations within the plant.

[0003] Training utilizing simulators is conducted by assuming various scenarios that may occur at a power plant, and teams execute procedures to respond to each situation.

[0004] However, current simulator training is centered around operators in the main control room. For example, regarding power plant information and operations that need to be verified on-site, field operators do not perform these tasks using equipment similar to the actual plant facilities; instead, they receive information verbally from a trainer responsible for the training and transmit it. Furthermore, when a request for operation is made by the main control room operator, the field operator requests the operation from the trainer rather than performing it directly, thereby executing the procedure in a manner different from how training is conducted in the actual field.

[0005] Furthermore, current simulators face difficulties during training and cannot even guarantee the effectiveness of education because they lack diverse interfaces for training tailored to various power plant situations and the capabilities of on-site operators.

[0047] The field operator customized training system (200) illustrated in FIG. 2 may include a communication module (201) and a virtualization system (210).

[0048] The communication module (201) supports real-time information exchange between the main control room operator (150) and the field operator (160), and shares the training situation through voice and data communication, so that the main control room operator (150) can monitor all situations occurring during training in real time and provide feedback.

[0049] The virtualization system (210) provides a virtual environment of the power plant necessary for training field operators (160) and may be composed of a field information receiving unit (211), a simulator (212), a user interface (213), and an equipment control unit (230).

[0050] The simulator (212) provides practical training experience to the field operator (160) by assuming various scenarios, and the field information receiving unit (211) can receive real-time data from the power plant information system (170) and reflect it in the simulator (212).

[0051] The user interface (213) can provide different educational content depending on the field operator's (160) grade and the power plant situation.

[0052] The device control unit (230) can transmit and execute operation commands entered by the field operator (160) through the user interface (213) to the actual field device (180).

[0053] In addition, the communication module (201) and the virtualization system (210) are connected so that the main control room operator (150) can receive information from the virtualization system (210).

[0054] FIG. 3 is a detailed block diagram of a virtualization-based customized training system for power plant field operators according to another embodiment of the present invention.

[0055] The field operator training system (300) illustrated in FIG. 3 may be composed of a communication module (310), a feedback module (302), a database (303), and a virtualization system (310).

[0056] The virtualization system (310) provides a virtual environment of the power plant and includes at least one user interface that provides a customized educational environment corresponding to the power plant situation and the level of the field operator (160) provided by the training instructor. The at least one user interface can provide content required for the training of the field operator (160) differently depending on the power plant situation and the level of the field operator (160). Here, the content may include screens required for training, procedures for the field operator to perform, and content to perform.

[0060] The first user interface (314) is composed of multiple field operator grade-specific training interfaces and may provide different screens that can be accessed or selected depending on the grade of the field operator (160). Here, the grades of the field operator (160) may be classified into entry-level engineer, intermediate engineer, and advanced engineer.

[0061] For example, screens necessary for driving scenarios can be automatically provided to entry-level engineers, some screens can be found and accessed independently by intermediate engineers, and all screens can be found and accessed independently by advanced engineers.

In emergency operation, a diagnostic interface that must be verified on-site for emergency situation diagnosis is automatically provided, and if unsatisfactory after verification, related measures may also be provided. In severe accidents, a screen for the field operator's actions in preparation for emergency situations may be provided.

[0066] The feedback module (302) can collect the field operator's (160) operation of the simulator (312) of the virtualization system (310), simulation results, and training evaluations and transmit them to the communication module (301), thereby allowing the field operator (160) to check their learning progress in real time and receive immediate feedback if necessary.

[0067] In addition, the training instructor can adjust the training content by reflecting the field operator's (160) user interface (312) operation history, device control unit (316) operation history, simulation results, and training evaluation through the feedback module (302).

[0068] The communication module (301) and the virtualization system (310) are connected via communication, so that the virtualization system (310) can provide the training status of the field operator (160) to the main control room operator (150) in real time.

[0069] The database (303) stores the training history data and training analysis data of the field operator (160) from the virtualization system (310), and the virtualization system (310) can generate user-customized training scenarios based on the training history data. That is, the learning effect can be maximized by analyzing the past training performance of the field operator (160) and providing a personalized learning path.
