Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plant simulator for training the operation of large-scale plant processes such as power plants.

For example, in nuclear power plants and thermal power plants, the operations of the plants are very complex, so it is necessary to conduct operation training so that the operations can be appropriately handled. For this,
Simulation devices for operator training (hereinafter referred to as simulators) have been manufactured and are being used to train power plant operators.

On the other hand, in order to meet the increasing demand for energy in nuclear and thermal power plants, the capacity of each unit has been increased, and as a result, the monitoring and control of power plants has become even more complex and sophisticated.
In response to this, electronic computers have been introduced in power plants for plant monitoring and control. In other words, with recent advances in computer utilization technology, conventional meters and recorders have been replaced with color CRT display devices driven by electronic computers.
In addition, computers are increasingly being used to monitor and control plants over a wide range of areas, including computer-based plant control. In addition, the electronic computers for monitoring and controlling power generation plants are becoming more and more complex, as a single arithmetic and control unit (CPU) cannot handle all of the monitoring and control. , the electronic computers for monitoring and control are also becoming more complex.
Therefore, when operating a power plant,
It is clear that computer failure has a major impact on plant operation.

However, few conventional simulators for operating training have taken into consideration the possibility of training against failures of electronic computers used for plant monitoring and control, and have had drawbacks in providing sufficient operating training. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a plant simulator that simulates failures of electronic computers that supervise and control power plants, thereby enabling sufficient operation training.

The present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 is an overall system configuration diagram showing the configuration of an embodiment of the present invention. The plant simulator of the present invention consists of a simulator computer 1, a control panel 2, an instructor console 3, and an operator console 4, and a printer 19 is connected to the simulator computer 1.

The simulator computer 1 has the same configuration as a normal computer, including an arithmetic and control unit 11, a main memory 12,
Auxiliary storage device 13, CRT control device 14, high speed process input device 15, high speed process output device 16
and a peripheral device 17. A printer 19 driven by this simulator computer 1
is connected.

The control panel 2 includes an operating device 30, a meter 31, and an alarm window 32.
and an automation console 18, and color CRT display devices 215-221. The color CRT display devices 215 to 221 display information from the simulator computer 1.

The operator console 4 has a color CRT display device 2 that displays information from the simulator computer 1.
13, 214 and an operator console keyboard 20. Furthermore, the instructor console 3 is equipped with color CRT display devices 211 and 212 for displaying information from the simulator computer 1 and an instructor console keyboard 21.

FIG. 2 is a block diagram for explaining the functions of the arithmetic and control unit 11 of the present invention. The operating state of the plant simulation device is set from the instructor console 3, and the setting data from the instructor console 3 is transmitted from the instructor console keyboard 21 via the CRT control device 14.
Alternatively, it is read into the arithmetic and control unit 11 of the simulator computer 1 from the instructor console 3 via the high-speed process input device 15. This setting data of the plant operating state is transmitted to the simulator function section 55 via the display control section 54 of the arithmetic and control unit 11.

On the other hand, the operating state on the control panel 2 is read into the arithmetic and control unit 11 via the high-speed process input device 15 and transmitted to the simulator function unit 55 via the input unit 53 in the arithmetic and control unit 11 . Based on the setting data and operation status read in this way, the simulator function unit 55 stores the main storage device 12 and the auxiliary storage device 1 of the simulator computer 1.
3, the operation of the power plant is simulated by calculations in accordance with a dynamic characteristic model and a control logic model, which are operational models of the power plant stored in advance. The result of the arithmetic processing is sent to the arithmetic control device 11.
The output unit 50 outputs the data to the instruments of the control panel 2 via the high-speed process output device 16.

The plant process computer function unit 52 of the arithmetic and control unit 11 simulates a plant process computer, and inputs the results of calculation processing by the simulator function unit 55 as a simulated input signal, and performs the necessary functions as a plant process computer. Execute. In other words, the scan
It performs calculations for logs/alarms, performance calculations, CRT display, etc., and outputs the results to the configuration control section 51.

The configuration control unit 51 is for simulating a failure of the plant process computer, and sends setting data of the configuration state of the plant process computer input from the instructor console 3 to the simulator function unit 55, that is, data on operation, stop, etc. According to the above, the configuration of the plant process computer is processed and the result is output as a signal to the high-speed process output device 16 via the output section 50.

The case where a plant process computer failure is simulated from the instructor console 3 will now be described. The plant process computer failure setting signal set on the instructor console 3 is input to the simulator function unit 55, and the result is input to the configuration control unit 51 as a plant process computer failure signal. When this process computer failure signal is input, the configuration control unit 51 disconnects all output signals from the plant process computer function unit 52 because the plant process computer is in failure. That is, the output signals from the plant process computer function 52 to the automation console 18 and the color
All output signals to the CRT display devices 213, 214 and further to the CRT display devices 215 to 221 of the control panel 2 are cut off. At the same time, a signal is output to the output unit 50 and the alarm window 32 of the control panel 2
A plant process computer failure output 40 for lighting up is outputted to the alarm window 32 via the high speed process output device 16, and the plant process computer failure window is turned on by a signal 41.

At the same time, another plant process computer failure output 42 is output from the high speed process output device 16 to the automation console 18, disabling the logic circuitry that enables automation and turning off the automation enable signal 43. Furthermore, the CRT control device 1
The output signal from 4 to the color CRT display devices 213 to 221 is also stopped, and all of the color CRT display devices 213 to 221 are made to be out of order. in this case,
All print output to the printer 19 is also stopped.
In this way, a failure of a plant process computer is simulated.

In the above embodiment, a power generation plant in which processing is performed by one plant process computer is simulated, but the present invention can be similarly applied to a case where the plant process computer is a multi-computer system.

FIG. 3 shows an embodiment in which the plant process computer consists of two processing units. Plant process computer function section 5

connected via.

In such a configuration, the CPU1 functional unit 521,
When all of the CPU2 functional units 522 are simulating a normal state, a simulated signal of the plant process amount is inputted from the simulator functional unit 55 to the CPU1 functional unit 521 via the switch unit SW1. A simulated output signal for controlling the plant by computer is output from the output section 50 to the high-speed process output device 16 via the configuration control section 51 via the switch section SW4. In addition, the display data on the CRT is sent to the CPU1 functional unit 52.
A signal is output from 1 to the CPU2 function section 522,
The CPU2 functional unit 522 performs calculation processing for CRT display.
The output signal is output to the configuration control section 51 via the switch section SW3, and an output signal is output from the display output section 54 to the CRT control device 14.

Consisting of two multi-computers like this,
When simulating a failure in the functions of the plant process computer, when simulating a failure in the CPU2 function unit 522, switch units SW2 and SW3 are switched to control the configuration so that the CPU1 function unit 521 can process all functions. do. In this case, for example, the automation console 18 operates by outputting the plant process computer failure output 42 and turning off the automation enable signal 43, and at the same time outputting the recovery signal 45 and activating the on-delay timer 46 to turn off the automation enable signal 43. Enable to turn on.

Furthermore, it goes without saying that the gist of the present invention can be applied regardless of the system configuration of the simulator computer 1, and can also be applied regardless of the system configuration of the plant process computer.

As described above, according to the present invention, it is possible to perform simulation training in the event that a plant process computer breaks down in a power generation plant operation training simulator, and therefore, it is possible to train operators more quickly. .
