Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a plant simulating device for carrying out plant operation training, and particularly to a plant simulating device that includes an on-site operation simulating panel and expands the training content. Regarding.

[Technical background of the invention and its problems] Plants for power generation, electric power, steel manufacturing, chemicals, etc. are becoming more complex and sophisticated year by year, and centralized control systems for these plants have also been widely adopted. There is. Plant simulators have been created and used for training in order to familiarize and improve the operating skills of operators of these plans.

Figure 1 shows an example of a conventionally used plant simulation device, which includes a plant simulation control panel 1 installed in a central control operation room (hereinafter referred to as central operation), and an arithmetic and control device 2 that performs plant simulation calculations. , which has an instructor console 3, an input device 4, and an output device 5, performs plant simulation calculations in response to the instructor's operation signal Us or the instructor's operation signal Is from the instructor console 3, and uses the result as a plant status signal Ps. The information was displayed using various lamps, indicators, etc. on the plant simulation control panel 1.

However, the number of devices that can be operated from the plant simulation control panel 1 provided in the central operating room is limited, and it is not necessarily possible to simulate the entire plant.

In addition, in order to train operators on how to respond, judge, operate, process, etc. in anticipation of plant accidents, breakdowns, or malfunctions and malfunctions in remote operations from central reactors, we prepare these accidents, breakdowns, and malfunctions in advance. It is equipped with simulation functions such as (hereinafter referred to as malfunctions). When such a malfunction occurs, the only way to recover is to operate the equipment attached to the plant simulation control panel 1 installed in the central reactor, and the only way to perform recovery operations is to conduct emergency recovery response training using on-site operations. There wasn't.

Even if an attempt was made to actually install various on-site devices, the number would be enormous, and space would be limited.

[Object of the Invention] The purpose of the present invention is to solve such problems by simulating on-site operation equipment and providing a on-site simulation control panel with a small installation space, thereby expanding the scope of application of plant simulation and making it more suitable for actual plant operation. The purpose is to provide a plant simulation device that allows for a wide range of operational training.

[Summary of the Invention] In order to achieve the above object, the present invention integrates equipment that represents on-site operations, such as on-off operating terminals for pumps, local switches for valves, and on-site operating terminals such as valve actuators themselves. , and a field operation simulation panel with field operation functions added thereto is installed on the input/output side of the arithmetic and control unit.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 2, 3, and 4. It is assumed that FIG. 2 is part of a system diagram of a certain plant. Pump A71. The pump B72, flow control valve 83, etc. can be operated from the plant simulation control panel 1 shown in FIG. 1, and the valves 84, 85, and 86 can be opened and closed only on site. In addition, pump A71,
Of course, the pump B72 and the flow control valve 73 can also be operated on-site.

Figure 3 shows on-site operation mock board 1 equipped with these on-site operation devices.
1 is shown. This on-site operation simulation panel 11 is a collection of on-site equipment, such as pump on-off switches 91, trip switches 92, and valves that are installed at the plant site as shown in the perspective view of FIG. Operation switch 93, valve handle 94, breaker 95, digital switch 96, 98, 100. Lamp 9'7. , 99 ,
10.1, etc., and by specifying the identification number of each operating device using the digital switch 96,
The pumps 71, 72 or valves 83, 84, 85, 86 shown in FIG. 2 can be operated as desired.

This device differs from the conventional device shown in FIG. 1 in that the field operation simulation board 11 configured as described above is connected to the input device 4 and output device 5 of the arithmetic and control unit 2 as shown in FIG.

In this case, for example, in the system shown in FIG. 2, assume that the flow rate adjustment valve 83 malfunctions and becomes inoperable from the middle stroke, and the following restoration work can be considered. First, if the valve 83 is to be moved manually on site, the identification number corresponding to the valve 83 is input using the digital switch 100 in FIG. This identification number is input to the arithmetic and control unit 2 via the input device 4 as a signal LJ S, I in FIG. Based on the input signal U s l , the arithmetic and control unit 2 recognizes that the signal input from the on-site operation simulation panel 11 indicates the valve 83 and indicates that it can be operated from the on-site operation simulation panel 11. .

The lamp 101 outputs a signal Ps= through the output device 5. When the trainee recognizes that this lamp 101 is lit and then operates the handle 94 or the up/down switch 93, the signal becomes the input to the arithmetic and control unit 2 again, and the physical characteristics of the plant are calculated based on this signal. The results are displayed on the plant simulation control panel 1 and the field simulation control panel 11 through output signals.

In the on-site simulation control panel 11, in addition to the valve operation section, the operations for starting and stopping the pump and opening and closing the breaker can also be operated using the same procedure.

[Effects of the Invention] As is clear from the above description, the present invention provides a simulated on-site operation panel that aggregates on-site operation terminals, and also includes on-site operation functions, so that all operations that can be performed by plant operators can be performed. This is a plant simulator that can greatly expand the range of simulations, have more depth, and provide more realism in training for responding to plant failures, with small equipment and installation space. realizable.
