Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant operation training simulator for, for example, a nuclear power plant.

(Prior Art) In general, recent process plants, especially nuclear power plants, tend to grow in size. Operating such a huge plant requires quite advanced knowledge and operating experience. Therefore, in order to ensure safe plant operation, it is necessary to sufficiently train plant operators.

A replica simulator with a simulated control panel that is identical to the control panel of the actual plant is most suitable for training plant operators. However, since this replica simulator is large-scale, it has the disadvantage of increasing costs. Furthermore, the replica simulator is large-scale, and it is necessary to return each operation switch on the operation panel each time an operation is completed. Therefore, when repeating a specific operation many times or training a specific event repeatedly, it is necessary to return a large number of operation switches, which also has the disadvantage of complicating the training.

Therefore, in the past, CRT (Cathode
A simulator has been proposed in which a touch screen is installed on a CRT display (Ray Tube) display device, and the device to be controlled is operated from the screen of the CRT display device via this touch screen. However, although such a simulator using a touch screen is a protein, it does not give the user the feeling of operating a real machine, that is, twisting or pushing a switch, and is therefore not suitable for getting a feel for the operation.

(Problems to be Solved by the Invention) As described above, although the replica simulator allows you to get the feeling of operating the actual machine, it is expensive and complicated to operate. Another problem is that a compact simulator that uses a touch screen does not give you the feeling of operating an actual machine.

This invention has been made in consideration of the above facts, and allows you to experience the operating feeling of an actual machine, and
The purpose of the present invention is to provide a plant operation training simulator that can reduce costs.

[Structure of the invention]

(Means for Solving the Problems) This invention is characterized in that one simulation operation switch of the same type as the operation switch of the actual machine is installed in different configurations, and that the number of simulation operation switches of the same type that can be operated simultaneously is A simulated control panel equipped with a simulated operation panel that is installed and has a nameplate that displays the name of the device to be controlled on each simulated operation switch;
A plant dynamics computer is connected to the simulated control panel and calculates and simulates the actual plant state based on the operation signals from the simulated operation switch, and a plant dynamics computer is connected to the simulated control panel and is controlled by the simulated operation switch. and a plant monitoring section that automatically switches and specifies each corresponding operation performed in response to the plant state calculated by the plant dynamics computer.

(Function) Therefore, according to the plant operation training simulator according to the present invention, the operation switch of the actual machine and the simulated operation switch of the same type are different from each other.
The number of simulated operation switches of the same type that can be operated at the same time is set up one by one, and these simulated operation switches function as operation switches for various devices to be controlled.

The touch screen 10 is installed on the screen of the CRT display device 8. This touch screen 10
For example, when an operator trainer touches and selects a symbolized device in the system diagram shown in FIG. 5.

As shown in FIG. 2, the simulated operation panel 9 includes a simulated operation switch 13 having the same form as the operation switch of the actual machine.
A, 13B, 13C, 13D... are installed in the minimum necessary number. The minimum required number means that one each of the simulated operation switches 13A, B, ... of different configurations are installed, and when operation switches of the same configuration are operated at the same time in an actual plant, they must be operated at the same time. This means that a number of simulated operation switches 13A, B, C, D, . . . of the same type are installed. Each simulated operation switch 13A, B,
Operation signals 12 from C, D, . . . are output to the plant dynamics computer 3.

Each of these status display lamps 14A, B, C, D, . . . displays the status at any given time of the operation target device that is the operation target of each of the simulated operation switches 13A, B, C, D, . . For example, in the case of the status display lamp 14B of the simulated operation switch 13B for the pump,

The above-mentioned plant monitoring section 5 shown in FIG. 1 has a plant status display function, an operation guide presentation function, and a simulated operation switch identification function.

The plant status display function is a function that inputs the plant status calculated by the plant dynamics computer 3 as the plant status signal 19 and causes the CRT display device 8 to display this plant status. The operation guide presentation function is a function for outputting and displaying the optimum operation guide according to the plant state as the operation guide signal 21 to the CRT display device 8.

The simulation operation switch specifying function is a function of switching and specifying the target equipment of the simulation operation switches 13A, B, C, D, . . . for each corresponding operation performed in response to the plant state. Specifically, this function includes a specific signal 23 and an operation target device recognition signal 2.

In other words, the plant monitoring unit 5 includes the equipment to be operated, the form of the operating switch of the equipment, and the simulated operating switch 1 having the same form as the operating switch.
The relationship between 3A, B, C, D, . . . is stored as data. Therefore, the plant monitoring section 5
In the case where the operation guide is presented, when the equipment to be operated is automatically selected according to the plant status, or when the equipment to be operated is selected by the equipment selection signal 11 from the touch screen 10. When selected, a simulated operation switch, for example, simulated operation switch 13B, corresponding to each device to be operated is specified. The plant monitoring unit 5 then selects any of the simulated operation switches 13.
Identification signal 2 indicates whether A, B, C, D, ... have been identified.

When this specific signal 23 is output to the simulated operation panel 9, the name of the device to be operated is displayed on the nameplate 15B of the identified simulated operation switch 13B on the simulated operation panel 9, and the identified simulated operation switch 13B is The indicator lamp 17B is lit. Further, when the specific signal 23 is input to the simulated operation panel 9, the status of the device to be operated at the time of input is indicated by the status display lamp 14B.

Next, the effect will be explained.

Operator trainers who are training nuclear power plant start-up procedures are using motor-driven reactor feed water pump A.
(M/D RFP-A) will be explained as an example. At this time, there are two cases: a case of starting based on a driving operation guide and a case of starting without a driving operation guide.

[] When an operation guide is presented, the plant monitoring unit 5 selects the motor-driven reactor feed water pump A as the device to be operated according to the plant state calculated by the plant dynamics computer 3.

The simulated operation switch 13B corresponding to the selected motor-driven reactor feed water pump A is identified, and the nameplate 15
The name of the motor-driven reactor feed water pump A is “M/D”.
RFP-A" is displayed and the instruction lamp 17B is lit. At this time, the "off" lamp of the status display lamp 14B is lit, indicating that the motor-driven reactor feed water pump A is in a stopped state.

Further, the plant monitoring unit 5 outputs to the plant dynamics computer 3 that the simulated operation switch 13B is the operation switch for the motor-driven reactor feed water pump A.

Therefore, the driver trainer uses the simulated operation switch 1.
When the lever 16B of 3B is operated to the starting side, the plant dynamics computer 3 determines that the motor-driven reactor feed water pump A has been started. Thereafter, the plant dynamics computer 3 calculates the plant state.

[] When the operation guide is not presented, the operator trainer determines by himself the target equipment to be operated (in this case, starting the motor-driven reactor feed water pump A) from the plant status displayed on the CRT display device 8. Then, the operator trainer touches the symbolized motor-driven reactor feed water pump A27 on the system diagram (FIG. 3) displayed on the CRT display device 9, and selects the motor-driven reactor feed water pump A. When this selection is made, the plant monitoring unit 5
identifies the simulated operation switch 13B of the motor-driven reactor feed water pump A, and writes the name of the motor-driven reactor feed water pump A “M/D RFP-A” on the nameplate 15B.
is displayed and the instruction lamp 17B is lit. Further, the "off" lamp of the plant status display lamp 14B is also lit.

Further, the plant monitoring section 5 identifies the simulated operation switch 13B as described above, and at the same time outputs to the plant dynamics computer 3 that the simulated operation switch 13B is the operation switch of the motor-driven reactor feed water pump A.

Therefore, the driver trainer uses the simulated operation switch 1.
When the lever 16B of 3B is operated to the starting side, the plant dynamics computer 3 determines that the motor-driven reactor feed water pump A has been started, and the subsequent plant state is calculated. In FIG. 3, reference numeral 29 represents a symbolic nuclear reactor, and reference numeral 31 represents a symbolic condenser.

Next, the effects of the embodiment will be described.

In this embodiment, simulated operation switches 13A, B, C, D, . . . have the same form as the actual operation switches.

In addition, the minimum necessary number of simulated operation switches that are the same as the operation switches of the actual machine are installed on the simulated operation panel 9, and the plant monitoring section 5 controls the devices to be controlled by the simulated operation switches 13A, B, C, D, . . . The simulation operation switch 13 installed on the simulation operation panel 9,
Since the number of A, B, C, D, . . . is small, the simulated operation panel 9 can be made compact, and costs can be reduced.

In the above embodiment, the simulated operation switch 13 on the simulated operation panel 9 is operated by the touch screen 10.
