[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant simulator used for operation training and analysis support of various plants such as a nuclear power plant and a chemical process plant.

[0002]

2. Description of the Related Art For example, in various plants such as a nuclear power plant and a chemical treatment plant, in order to operate the plant safely and stably, not only the operator of the plant can smoothly perform normal operation However, it is required to have the ability to promptly take measures when an abnormality occurs.

Therefore, as a device for training plant operators, various plant simulation devices have been developed, including a simulation device (simulator) for operation training. Such a plant simulation device for operation training has a function of performing trend registration / display in addition to simulation of the plant state at the time of starting / stopping, occurrence of abnormality, and the like.

FIG. 25 shows an example of the configuration of a conventional plant simulation device. In FIG. 25, reference numeral 1 indicates a simulation control panel. The simulation control panel 1 is provided with operation switches 2, an indicator lamp 3, an indicator 4, and the like. Further, a plant dynamic characteristic simulation means 5, a process data file 6, a process display means 7, a display device 8 such as a CRT, etc. are arranged on the simulated control panel 1. When the operation switch 2 is operated, the plant dynamic characteristic simulation means 5 causes
The plant dynamic characteristic is calculated according to the operation contents of the operation switch, the calculation result is written in the process data file 6, and the contents of the process data file 6 are displayed by the process display means 7 on the indicator lamp 3, the indicator 4 and the display. It is configured to be displayed on the device 8.

Further, the plant simulation device is provided with trend registration / display means 10 configured to input a trend registration / display request by an input device 9 such as a keyboard. In addition to the above-described normal operation, the instructor (operator) inputs a trend registration / display request to the trend registration / display means 10 using the input device 9, whereby the trend registration / display means 10 causes the trend data file. 11. The trend is registered in 11 or the trend is displayed in the display device 8 through the process display means 7.
It is configured to register / display trends.

As a supplementary explanation of FIG. 25, FIG. 26 shows an example of a concrete hardware configuration of the plant simulation device.
The plant simulation device is mainly composed of a simulation control panel 1 provided with operation switches 2, an indicator lamp 3, and an indicator 4 necessary for operation / monitoring, and a plant simulation computer 12. Further, the plant simulation computer 12 includes a disk device 13 which stores each unit shown in FIG. 25 as software and stores the software as a program, a central processing unit 14 and a memory 15 for executing the program, and a simulation control panel 1. Input device 16 for inputting the switch state of No. 1, digital output device 17 for turning on / off the indicator light 3 on the simulated control panel 1, and analog output for outputting the indicated value of the indicator 4 on the simulated control panel 1. A device 18, a display device 8 such as a CRT for displaying an analysis result, an input device 9 such as a keyboard for inputting data and a command of an operator, and a touch panel 19 are included.

Generally, in a plant simulator, the simulated control panel 1 often has the same shape on the surface as that used in an actual plant in order to give a sense of realism. However, unlike a control panel for an actual plant, circuits such as an internal relay sequence are not present because they are simulated by the software of the plant simulation computer 12.

In recent years, the control panel tends to be computerized. In this case, the digital input device 16, the digital output device 17, and the analog output device 18 are provided between the simulation control panel 1 and the plant simulation computer 12. In many cases, data is transmitted and received by the data transmission device 20 without being connected.

In such a plant simulation device, the plant dynamic characteristic simulation means 5 operates as shown in FIG. First, the state of the operation switch 2 on the simulated control panel 1
When input by the digital input device 16 (step 1
00), the relay sequence (logic) is simulated by the change in the switch state, and it is determined whether the operation performed by the operator is valid (step 101). When the logic condition is satisfied, the characteristics of the operating device (actuator) such as the pump and the valve are simulated, and the pump O
Calculation of N / OFF characteristics and valve opening (step 1
02).

Then, the dynamic characteristics of the process such as flow rate and pressure are calculated from the state of the operating equipment (step 103). The dynamic characteristic model to be simulated is generally a physicochemical model so as to correspond to all operations and exhibit the same characteristics as the actual machine. After the calculated process characteristics are converted into engineering values, a voltage value and a current value corresponding to the indicator 4 on the simulated control panel 1 are output from the analog output device 18 and displayed on the indicator 4 (step 104). Further, the calculated characteristics of the process are used not only for display on the indicator 4 but also for relay sequence simulation calculation (step 105). For example, when an alarm value and an interlock operation set value are provided for a certain process value, the digital output device 17 digitally outputs the indicator lamp on the simulated control panel 1 according to the state. The indicator lamp 3 is turned on / off (step 106).

The relay sequence simulation is repeated until the simulation is completed and the plant becomes stable (step 107). That is, when the relay sequence operates and the actuator such as the valve operates according to the calculation result of the process characteristics (including the operation by the protective interlock), the related dynamic characteristic simulation is performed again.

[0012]

(2) It was not possible to execute a simulation in which plant data were connected between mutually related plants.

(3) It is necessary to register the trend data each time a different plant is simulated, which imposes a heavy burden on the operator.

The present invention has been made in response to such a conventional situation, and a plurality of plant simulation devices can be executed by one plant simulation device, and the operation training effect can be improved as compared with the conventional case. An object of the present invention is to provide a plant simulating device that can perform.
