[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training simulator for training operators of thermal power plants of power companies and operators of various plants in normal operations and accident response operations. is there.

[0002]

2. Description of the Related Art Recent thermal power plants have become very complicated due to the increasing capacity and automation. Extensive knowledge and advanced operating skills are required to operate this equipment efficiently and safely. The simulator for thermal driving training is a training device that simulates the operation control of a power plant, and the movements of a boiler, turbine, generator, etc. are calculated by an electronic computer, and training is performed with the same sensation as operating at an actual power plant. You can do it. By using this simulator, you can repeatedly perform accident response training that you can hardly experience in actual driving, so you can perform effective training in a short period of time. For example,
Approximately 200 types of abnormal phenomena such as power line accidents, major equipment failures, automatic control equipment failures, etc. can be generated arbitrarily and in duplicate, and accident response training that cannot be experienced in actual operation can be performed. Approximately 50 types of unit operating states such as before boiler ignition, before turbine startup, before parallel, 4/4 load, etc. can be arbitrarily selected, and training can be started from that state, and 5 minutes during training 6 at intervals
You can revert to the state of 0 minutes ago, you can easily perform repeated training such as accident handling, you can temporarily stop the movement of the unit during the training, and there is an interruption during the training etc. However, the training can be resumed from that state. FIG. 8 shows, for example, JP-A-59-914.
It is a block diagram which shows the system structure of the conventional training simulator (conventional example 1) shown by Unexamined-Japanese-Patent No. 76. In addition,
This conventional example 1 is a conventional technique corresponding to the invention of claim 1. In FIG. 8, reference numeral 41a denotes a central processing unit (CPU) of the digital computer, which performs processing corresponding to the role of the trainer. 42a is a main memory, 43a is a trainer table, 4
4a is a CRT display device mounted on the trainer console 43a,
Reference numeral 45a is an external storage device, and 47 is a shared main storage device accessible from each CPU. A central processing unit 41b of the digital computer performs a process corresponding to the role of the trainee. 42b is a main storage device, 43b is a trainee console, 44b is a CRT display device mounted on the trainee console 43b, 45b is an external storage device, and 46 is a system monitoring board. Reference numeral 41c is a central processing unit of a digital computer, which performs power system simulation and various plant simulations. Reference numeral 42c is a main storage device, and 45c is an external storage device accessible from each CPU.

Next, the operation will be described. In FIG. 8, the trainer table 43a and the CRT display device 44a are used to create and register a training pattern (referred to as advance preparation). The end of advance preparation is done with the "end of preparation" push button. Next, in order to actually carry out the training, the "training execution" is activated from the trainer table. This puts the simulator in run mode. In run mode, the trainer can terminate training at the appropriate time with the "End Training" push button. As shown in FIG. 9, when the training is to be reproduced after the training is completed, the “Reproduction mode” button is displayed by pressing the “Reproduction mode” button, and the “Record training status record” button set during the execution of the training is pressed. Set the reproduction start time and reproduction end time arbitrarily from the timing and training start and end time,
"Start reproduction" The reproduction of the training is started by the light pen instruction. If you want to stop the reproduction on the way, display the "reproduction mode setting table" on the CRT with the "training reproduction" push button,
The reproduction mode is ended by the "reproduction stop" light pen instruction. If the "training reproduction" button is not pressed during the reproduction, the reproduction is continued until the reproduction end time. In any of the above cases, by newly setting the reproduction start and end times, it is possible to repeat the reproduction any number of times by arbitrarily setting the start and end times.

By the way, recent training simulators have a backtrack function, that is, a function of returning the plant state to an appropriate time and then restarting the operation training once the operation training has been carried out. For example, FIG. 10 shows a schematic explanatory diagram of data storage in a backtrack function provided in a conventional training simulator (conventional example 2). The conventional example 2 of FIG. 10 is a conventional technique corresponding to the invention of claim 2.

The backtrack function saves the data of the plant simulation characteristic at each data storage cycle (ts, ta, tb ...) (dts, dta, dtb ...).
The saved data dts, dt as the initial value when the training is restarted
a, dtb ... Can be arbitrarily selected and used. The instructor first observes the training status of the trainee (operator under training), and confirms the progress status of the content, the proficiency level of the training, the confidentiality of the simulated plant status, and the accuracy of the trainee's response to the plant status. Etc. Then, when an instructor (instructor) finds an error in selecting a task (a series of operations for achieving a driving guide) or an erroneous operation, the instructor notes the findings. Next, after the training is completed, the instructor evaluates the task selected by the trainee and the operation performed based on these memos, recognizes an error in the task selection or an erroneous operation, estimates the reason, and informs the exerciser. After that, using the backtrack function of the plant simulator, the plant status is returned to the point when there was an error in task selection or erroneous operation (backtrack point), and training is performed again from that point, so that the trainee can operate correctly. I try to acquire the skills.
