Description

  The present invention relates to a training simulator, and more particularly to a training simulator for power system equipment having a training reproduction function.

  Training of operators using a training simulator is being carried out in order to improve the operation technology of supervisory control systems for power systems. For training, the database of the power system used for actual operation is used, and training close to actual operation has become possible. As a training system, there are a side-by-side training simulator implemented as a part of a function in a monitoring and control system in actual operation, and a stand-alone training simulator installed in a training facility as a dedicated training system.

  Training is roughly divided into three stages: training preparation, training execution, and training evaluation. Correspondingly, the training system has different modes such as a training preparation mode, a training execution mode, and a training evaluation mode. In the training preparation, various settings such as the load value of the power equipment and the state of the power equipment in the initial power system at the start of training execution are performed.

  In recent years, a function of storing online information of a real system as system information for training has been proposed. Accident scenarios that occur during training are also prepared during training. In executing the training, the trainer (instructor) generates an accident scenario created in the set system state at an arbitrary timing. Trainees (trainers) perform power system restoration operations for accidents that occur, and receive accident response training. In the training evaluation, the trainer evaluates and provides guidance on the accident response of the trainee during the training.

  For the purpose of evaluation support, an operation history storage function has been implemented, and video recording of training situations has also been carried out. The use of video footage is carried out for the purpose of evaluating the training process, but there are still problems such as not being associated with the operation history and being unable to grasp the detailed training situation such as screen operation. .

  For the purpose of evaluating whether the operation procedure of the trainee is correct, a training simulator that implements a mechanism for storing the accident recovery operation procedure is known (for example, Patent Document 1 and Patent Document 3). However, the operation screen and the trainee's behavior at that time cannot be known only by the operation procedure, and it is difficult to grasp under what circumstances the operation is wrong.

  Regarding recovery operations, there are various patterns of recovery methods for the same accident. At present, it is not possible to resume from the state in the middle of the training execution after the training is completed, so it is not possible to efficiently train the recovery operation of a plurality of patterns. Training based on the system state at the time of the actual accident can be performed by storing the facility information of the system facility at the time of the actual accident and reproducing the facility information from the stored data (for example, Patent Document 2). ). However, it is not assumed that the system state during the training is saved, and if there is an error in the recovery operation during the training, the training cannot be resumed from the middle of the training.

  The present invention has been made to solve the above-described problems. The mouse operation, keyboard input, and desk button operation during training execution of the trainee and the trainer are stored as an operation history, and the entire system during training execution is stored. The purpose is to provide a mechanism that can reproduce the behavior.

Training simulator to target such power system equipment to the invention, and the system state database accident scenarios that target electric power system equipment, where and initial system state corresponding to the accident scenario is more conserved, with respect to the input device an operation history database operation history is recorded in association with the corresponding operation history count operation order, the system casing consists of the difference between the system state when the initial system state store command has been input lines case A training table that displays and reproduces training accidents by reading out the accident scenario, initial system state, operation history, and system case from the system case database recorded in association with the number , system state database, operation history database, and system case database. It has. When a save command is input during training, the training table creates a system case and associates the created system case with the system case number in the system case database.

  According to the present invention, since the trainer has a function capable of storing and reflecting the load value of the electric power equipment and the state of the electric power equipment at any timing during the execution of the training, a mechanism that can resume the training from the middle of the training execution is provided. Is done. By combining the operation history storage and the reproduction function, it is possible to reproduce the training situation from an arbitrary timing.

  Embodiments of a training simulator according to the present invention will be described below in detail with reference to the drawings. In addition, this invention is not limited to the following description, In the range which does not deviate from the summary of this invention, it can change suitably.

Embodiment.
FIG. 1 is a block diagram of a training simulator used for carrying out the present invention. The training simulator 100 includes a system state database 1, a system case database 2, an operation history database 3, and a training table 10. The training table 10 is prepared for the number of trainees. The trainee sits on the training table 10 assigned to each trainee and receives training. Various modes such as a main menu, a training execution mode, a training evaluation mode, and a training reproduction mode can be selected from the monitor of the training table 10. The system state database 1 stores accident scenarios (training accident 1 to training accident N). In the training preparation stage, various settings such as the load value of the power equipment (for example, the generator, the circuit breaker, and the load) and the state of the power equipment in the initial power system at the start of training execution are performed. As shown in FIG. 2, the system facility setting values and the like are stored in the system state database 1 at the start of training.

The training table 10 includes a CPU (Central Processing Unit) that manages the system state database 1, the system case database 2, and the operation history database 3. When the trainee executes the training process through the operation screen of the training table 10, the training simulator 100 saves the operation content for the input device during the training as the operation history in the operation history database 3 as needed. The training table 10 includes a mouse, a keyboard, and a table button (button) as input devices. The table button includes a button displayed on the monitor. The operation history database 3 can store M cases from the operation history 1 to the operation history M. Here, a case from the start to the end of the operation recording process is taken as one case. In the operation reproduction process, the operation history is reproduced by automatic operation while referring to the operation history database 3 by selecting and executing the operation history to be reproduced by the trainer.

  When the trainer executes the system information storage operation through the operation screen of the training console 10, the training simulator 100 stores the system information in use in the training from the system state database 1 in the system case database 2 when the process is executed (see FIG. 7). . In saving, the difference between the system state at the start of training and the system state at the time of execution of the process is extracted, and this difference is stored. The system case database 2 can store N cases from the system case 1 to the system case N. In the system information reproduction operation, the selected system case is copied from the system case database 2 to the system status database 1 being used for training and reflected in the data (see FIG. 8).

FIG. 3 shows a training flow. When training is started, the trainer selects an arbitrary training accident n from training accidents 1 to N. A system image is displayed on the training table for the selected training accident n. The trainee performs training recovery on the displayed system image of the training accident n. The restoration operation includes an operation using a mouse, a keyboard, and a desk button. These operation histories are always stored in the operation history database 3 during training (see FIG. 4). When a situation occurs where the trainer feels it necessary to reproduce the accident, the trainer presses a button to record the system status at the time of training. In this case, since only the necessary part is recorded, the memory can be reduced. When a situation in which the recovery operation is desired to be reproduced occurs after the recovery operation is completed or during the progress of the recovery operation, the system information reproduction operation is selected (see FIG. 6). The training ends when it is no longer necessary to select the system information reproduction operation.

  The training simulator 100 stores the system state at an arbitrary timing during execution of training. New training can be started at any time from the case recorded during training. It is also possible to pause from the specified case while reproducing the operation history, and start a new training from there. By performing the training again from the saved timing, it is possible to try the accident system restoration operation, so the improvement of the training effect can be expected. In addition, it is possible to reproduce the system operation performed by the operation history storage function and the operation history reproduction function, so that the operation performed by the trainee himself can be understood from a third party's point of view, and the trainer can evaluate the training process. It can also be used.

FIG. 4 is a flowchart showing the operation recording process. The operation recording process is performed in a synchronized state in all training tables. The operation recording process records all the operation contents only during training execution. First, when training is started, an initial value of an operation history count indicating the execution order of operation contents is set, and a transition is made to an operation waiting state. The operation content recorded as the operation history is intended for mouse operations, keyboard input, and console button (button) operations by the trainer and trainee. When the mouse is operated, the position of the cursor on the screen and the click or click release state are stored as the operation content. When there is a keyboard input, the unique number assigned to the input key is stored, and when there is a desk button operation, the unique number assigned to the desk button is stored. Next, the operation time is stored for linkage with the system information reproduction function. Then, the value of the operation history count is saved, and a transition is made to an operation waiting state. When the training is finished, the operation recording process is also finished. FIG. 5 shows an example of the operation record created at this time. The operation record is stored in the operation record database 3.

FIG. 6 is a flowchart showing the operation reproduction process. The operation reproduction process executes automatic operation in a synchronized state in all training tables. The operation reproduction process reproduces the operation history only during execution of training. First, a system case number for which a reproduction operation is desired is designated, and an initial value of an operation history count indicating the execution order of the operation contents is set. Each time the operation history is reproduced, the count value is added. By setting a specific desk button for pause, a pause operation of the operation reproduction process is accepted. The training simulator 100 reads the operation content of the operation history corresponding to the set operation history count from the operation history database 3, and reproduces the operation content. When the operation for one count is reproduced, the value of the operation history count is added, and a transition is made to execution of the next operation history. When the operation pause is accepted, the main menu is restored. When you return to the main menu, you can select accident 1 to accident N newly. An end operation of the operation reproduction process is accepted by setting a specific desk button for the end. When the counter reaches the final value or when the stop button is pressed, the reproduction process ends.

  FIG. 7 is a flowchart showing the system information storage operation. The system information saving operation starts when the trainer presses the save button during training. When the system information storage operation starts, the current system state is stored in the system case database 2 as a new system case. When the system information is stored, the operation history count value at that time is also stored. As a result, the operation history can be reproduced from the state in which the system state is reproduced.

  FIG. 8 is a flowchart showing the system information reproduction operation. FIG. 8 corresponds to preprocessing for executing the flowchart shown in FIG. The system information reproduction operation can be performed during training. When the system case to be reproduced is selected and executed, the selected system case is reflected in the system state. In the system case selection screen, the time information of the system case is displayed to facilitate linkage with the video image. After performing initial system calculation, training is possible in the system state after reproduction.

  In the present invention, the embodiments can be appropriately modified and omitted within the scope of the invention.
