Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plant simulator for training operators on how to respond to plant abnormalities.

Recently, in order to train plant operators,
Plant simulators are used. The main purpose of this plant simulator is to train normal operation and handling as well as how to deal with accidents that occur at actual plants.In the manufacturing stage, plant accidents are taken into consideration and incorporated into the model. There is. On the other hand, recently there has been a demand to expand the range of assumed accidents. However, current plant simulators cannot incorporate accidents other than those set at the time of manufacture. Therefore, it is not possible to satisfy the above-mentioned demands of instructors, which is causing problems.

This invention was made based on the above circumstances, and it is an object of the present invention to provide a plant simulator that satisfies the request for expanding the scope of accidents and can train operators for all types of accidents. The purpose is to

An embodiment of the present invention will be described below with reference to the drawings.

The figure is a block diagram showing the configuration of a plant simulator for a nuclear power plant. In the figure, reference numeral 1 denotes an instructor console, which outputs a command signal S1 according to an operation. 2 is a simulated central control panel that is the same type and has the same functions as the central control panel of a nuclear power plant, and includes control rod operation switches 3, push buttons, lamps, alarms, setting devices, neutron flux indicator 4, neutron flux recorder 5, etc. It is equipped with Reference numeral 6 denotes an input/output device, which is an interface between the instructor console 1, the control panel 2, and the arithmetic and control unit 7.

The arithmetic and control device 7 inputs a command signal S1 from the instructor console 1 and an operation signal S2 from the control rod operation switch 3, push button, setting device, etc. via the input/output device 6, and performs predetermined procedures and It performs arithmetic processing according to the method and gives the result of the calculation as a display signal S3 via the input/output device 6 to the lamp, alarm, neutron flux indicator 4, neutron flux recorder 5, etc., and the input/output function section 8 , a common data section 9, a model calculation section 10, and a command function section 11. The input/output function section 8 sends and receives signals to and from the instructor console 1 and the control panel 2.
Switches, push buttons, setting devices, lamps on control panel 2,
All equipment numbers corresponding to alarms, indicators, recorders, etc. are memorized. Common data section 9
has an input data section 9a and an output data section 9b for exchanging information with the control panel 2 and instructor console 1, and an internal data section 9c for storing and referencing information with the model calculation section 10. The model calculation unit 10 operates on switches, push buttons, etc. on the control panel 2.
It performs simulated calculations of the plant according to the status of setting devices, etc. The command function section 11 gives commands to the input/output function section 8 using command signals S1 from the common data section 9 that stores input/output signals and plant model calculation results and from the instructor console 1.

Next, in the above configuration, the operation will be described assuming that an accident occurs in which the needle of the neutron flux recorder 5 becomes stuck while monitoring the neutron flux in the core of a nuclear power plant.

Now, when the control rod operation switch 3 installed on the control panel 2 is operated, the operation signal S23 is given to the arithmetic and control unit 7 via the input/output device 6, and is sent to the common data section via the input/output function section 8. 9 is stored in the input data section 9a. The operation signal S23 stored in the input data section 9a is input to the model calculation section 10, and the control rod position is first calculated and stored in the internal data section 9c. Subsequently, the model calculation section 10 calculates the control rod reactivity from the control rod position and stores it in the internal data section 9c, and also calculates the neutron flux value and stores it in the output data section 9b.

Furthermore, a display signal S3 is always output from the input/output function section 8 to the lamp, alarm, indicator, and recorder on the control panel 2 via the input/output device 6 based on the value of the output data section 9b. For example, the neutron flux value is given to the neutron flux indicator 4 and neutron flux recorder 5 as display signals S34 and S35. However, when a command indicating that the equipment number corresponding to the neutron flux recorder 5 is fixed is generated from the instructor console 1, the command signal S1 is stored in the input data section 9a in the common data section 9 via the input/output device 6. be done. Further, a device number is input from the input data section 9a to the command function section 11, and the fact that the instrument corresponding to the device number is in a fixed state is transmitted from the command function section 11 to the input/output function section 8. As a result, the value of the display signal S3 of the meter 1 corresponding to the device number is not calculated from the value of the output data section 9b, but is left unchanged from the previous value. For example, the value of the display signal S35 to the neutron flux recorder 5 is left unchanged from the previous value.

Therefore, on the control panel 2, the neutron flux indicator 4 responds in accordance with changes in the neutron flux value, but the needle of the neutron flux recorder 5 does not waver, simulating a stuck state. Further, if the device specified from the instructor console 1 is a lamp, a burnout of the lamp is simulated, if it is an alarm, its failure is simulated, and if it is a switch, push button, setting device, etc., a poor contact is simulated.

As described above, according to this embodiment, the command values issued by the operator's operation of the operation training operation switches, push buttons, setting devices, etc. on the control panel 2 are not used, but the insertion from the instructor console 1 is performed. Using the operation command value, the model is calculated as if it were operated, and a command value different from the model calculation result is displayed and output on the lamp, alarm, indicator, recorder, etc. on the control panel 2. Therefore, it is possible to train for accidents other than those set at the time of manufacture, and for malfunctions within the control panel 2, that is, all switches, push buttons, setting devices, lamps, alarms, indicators, memory meters, etc. on the control panel 2. It is possible to simulate an accident from the instructor console 1. Furthermore, even if an accident occurs with a certain device on the control panel 2, it becomes possible to train operators so that they can quickly respond using other devices, leading to improved plant safety.

Note that this invention is not limited to the above embodiments. For example, as the command signal S1 from the instructor console 1, not only the equipment number but also
It is also possible to insert the point in time at which the device breaks down, and to transmit the information to the input/output function section 8 when the command function section 11 determines that the specified point has been reached. In addition, by inserting an operation value (for example, on or off for a switch or push button, or a setting value for a setting device) as the command signal S1,
The operation value is input from the command function unit 11 to the input/output function unit 8.
The input data section 9 of the common data section 9
a, and the model calculation section 10 calculates the operation values according to the operation values, thereby making it possible to conduct driving training only from the instructor console 1. Other modifications may be made without departing from the gist of the invention.

As explained above, according to the present invention, even if there is a request to expand the range of accidents, it is possible to obtain a plant simulator that satisfies the request and can train operators for all types of accidents.
