Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant operation training support system applied to operation training for responding to various plant events in boiler plants and the like.

0002

BACKGROUND OF THE INVENTION A conventional device for operating training education for responding to various plant events includes a status display panel 21, a monitoring monitor 22, an indicator 23, a switch 24, and a monitor 22, as shown in FIG. The same specifications as the control panel in the plant's central control room were used, which included a monitoring panel 27 equipped with a graphic screen as shown in FIG. 3(b). This is called a replica type simulator.

[0003] In this replica type simulator,
Since it is possible to simulate the same as the actual machine, training on plant operation can be conducted with a sense of realism in the atmosphere of operating the actual machine, and the operating procedures etc. can be learned exactly. However, when it comes to sudden changes such as plant accidents, it takes time and is difficult to determine the cause of the problem unless plant operators have gained a lot of experience.

[0004] In conventional equipment, the status is displayed on the plant display panel, which is roughly categorized by function, based on information from the plant computer, and sudden changes are displayed individually, and alarms and warnings are also provided to call for attention. Although audio announcements were made, it took time to confirm the event.

[0005] The above-mentioned plant status (of equipment, etc.) can be judged from the display, but since it is difficult to grasp the status value intuitively, it is difficult to perform training and operation while understanding all the phenomena in the plant. It was difficult.

[0006]

[Problems to be Solved by the Invention] In conventional equipment, training events are alerted by voice announcements and alarms, and status is displayed by lighting lamps on the control panel, just as in the actual equipment. In order to understand the situation, analysis is performed later based on trends and data from the occurrence of the event, and it takes time to take any steps to deal with the event. What events occur where,
This is because it takes time to understand what kind of impact it has on the plant. Additionally, depending on the event, the response methods differed depending on the operator's experience and subjectivity.

The present invention aims to solve the above problems.

[0008]

[Means for Solving the Problems] The plant operation training support device of the present invention includes a learning determining means for inputting plant information from an operation panel simulating an actual machine, determining display contents, and determining its importance level. A display management means inputs the display contents and importance level, determines the display format and display method, and inputs and displays a display screen showing the state quantities and behavior of the plant on the display device, and inputs the plant information from the operation panel. It is characterized by being equipped with an information processing means to which a plant characteristic model section and a database section are connected and determining operation guidance, and a console that can input and display operation guidance from the information processing means and also allow setting of various conditions. .

[0009]

[Operation] In the above, when a certain event occurs in the plant, the learning judgment means inputs the plant information from the operation panel that simulates the actual machine, and the plant state quantity (observed value of the simulator) and the plant information that can be displayed. Automatically determines the display content and determines the importance of the event's impact on the plant. The output of the learning judgment means is input to the display management means, and the display management means displays state quantities (enthalpy, etc.) of the plant (equipment, etc.) that are not observed even in actual equipment, and their trend graphs. It manages data, automatically changes the display screen size over time, and recognizes and learns from the differences in display formats and methods used by individual operators.

[0010] The above plant information is also input to the information processing means, and the information processing means uses the data of the plant characteristic model section to perform a simulation using a separate startup program for events that occur during or before and after the operation training. It makes it easy for operators to understand plant behavior and internal conditions during plant simulation, and allows operators to learn the causes of events, how to deal with them, etc. by modifying setting conditions via the console. Knowledge can be registered in a database and messages such as driving operations for the next driver training or operation guidance for another operator's training can be displayed.

[0011] According to the above, the window display is enlarged depending on the importance of the event occurring in the plant and the passage of time, so that the operator can quickly respond, and the behavior of the plant and the phenomenon can be confirmed during or before and after the training. This makes it easier for operators to intuitively understand the plant status, and provides operational guidance, thereby realizing a device that enables efficient operation training and learning.

[Embodiment] An embodiment of the present invention will be explained with reference to FIG. The plant operation training support device 11 of this embodiment shown in FIG.
A learning judgment means 4 inputs plant information via an input processing unit 2 and a plant computer 3 from an operation panel 1 that simulates an actual machine, determines display contents, and determines its importance; Display management means 5 which inputs the degree, determines the display format and display method, and inputs and displays a display screen showing the state quantities and behavior of the plant on the display device 6;
Information processing means 7 inputs plant information from the plant computer 3 and is connected to a plant characteristic model section 8 and a database section 9 to determine operation guidance, and inputs and displays operation guidance from the information processing means 7, as well as various conditions. It is equipped with a console 10 on which settings can be made.

[0013] In the above, data is collected by the input processing section 2 which inputs plant information from the operation panel 1 which is a plant simulator that simulates an actual machine, and the data is converted into engineering values by the plant computer 3. The results are input to the learning determination device 4, which determines what can be displayed on the display device 6, determines what kind of influence the occurring event has on the plant, and determines the importance of the event. According to this degree of importance, the display management means 5 changes the size, color, etc. of the window to be displayed on the display device 6.

[0014] Here, in order to learn the display method for each operator, a display device 6 suitable for each operator is configured. If an operator fails to take any action or overlooks an event that has occurred, it will be displayed in a larger size over time to call the operator's attention. These displays make it possible to easily confirm events during training.

[0015] Furthermore, the data from the plant computer 3 is
It is also input to the information processing means 7. Here, it is assumed that the results of the simulator are regarded as plant observation values, and data about the events that have occurred are sent to the plant characteristic model section 8, so that the following can be carried out in the operator training process.

One is to save the data and check the function later using the information processing means 7 after the plant simulation is finished, and also to check the behavior of the plant later from the data during training. or modify and execute the set conditions from the input console 10 to help understand plant characteristics. The second method is to use various training data for plant analysis and enable efficient plant operation training.

For example, during operation training, in the case of a runback operation called a special operation state in a boiler plant, etc., there is a sudden decrease in water supply, etc., but in this embodiment, the learning judgment means 4 and the display management means 5 to efficiently display the phenomena and state quantities of the plant on the display device 6, and furthermore, to show the behavior of the plant etc. by the information processing means 7 in order to let the user understand what kind of phenomenon will occur next during the training. Operators can intuitively understand this. Further, since the next driving operation can be organized step by step, driving training can be performed efficiently and the severity of the event can be learned from the display device.

By inputting these series of driving operations as knowledge into the database section 9 of the information processing means 7, operation guidance etc. for the same event can be displayed to another learner, and the above-mentioned things can be done. Combined with this, operators can be provided with organized knowledge and training.

Note that FIG. 2 shows an example of a display by the display device of this embodiment, and (a) shows a normal single screen display 12.
(b) is a multi-window display 13 in which the arrangement and coloring within the window can be adjusted by the operator. (c) is display 14 when some kind of event occurs in the plant, and (b) shows that the event in (c) is of high importance, and the message screen gradually becomes larger due to insufficient processing despite the warning. This is display 15 when displayed.

[0020] According to the above, the window display is enlarged depending on the importance of the event occurring in the plant and the passage of time, so that the operator can quickly respond, and the behavior of the plant and the confirmation of the phenomenon can be carried out during or before and after the training. This makes it easier for operators to intuitively understand the plant status, and provides operational guidance, thereby realizing a device that enables efficient operation training and learning.
