Description

Detailed Description of the Invention

[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 nuclear power plants and chemical process plants.

[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, it is necessary for a plant operator to perform normal operation smoothly. In other words, the ability to promptly take measures when an abnormality occurs is required.
Therefore, as a device for training operators of a plant, various plant simulation devices such as a simulator for operation training have been developed. Many of the plant simulators for operation training described above are configured so as to be able to simulate the plant state at the time of an accident in addition to the plant state simulation at the time of start / stop.

FIG. 23 shows an example of the configuration of such a conventional plant simulation device.

In FIG. 1, an operation switch 2, an indicator lamp 3, an indicator 4 and the like are provided on a control panel 1, and the control panel 1 has a plant dynamic characteristic simulation means 5, a process data file 6 and a process display. Means 7 and CRT 8 etc. are installed. On the other hand, the plant dynamic characteristic simulating means 5 is provided with an accident simulating setting means 11 configured to be able to input an accident simulating setting request 10 with an input device such as a keyboard 9.

With the above configuration, the operation switch 2 on the control panel 1
Is operated, the plant dynamic characteristic simulation means 5 calculates the plant dynamic characteristic according to the operation content of the operation switch 2,
Write this calculation result to the process data file 6,
The contents of the process data file 6 are displayed on the indicator lamp 3, the indicator 4 and the CRT 8 by the process display means 7.

FIG. 24 shows an example of a concrete hardware configuration of the plant simulation device shown in FIG.

The plant simulation device is mainly composed of a control panel 1 equipped with operation switches 2, an indicator lamp 3 and an indicator 4 necessary for operation and monitoring, and a computer system 50. The computer system 50 converts the respective means shown in FIG. 23 into software and stores a disk device 51 for storing the software as a program, a central processing unit 52 and a memory 53 for executing the software, and switch states on the control panel 1. A digital input device 54 for input, a digital output device 55 for turning on / off the indicator lamp 3 on the control panel 1, an analog output device 56 for outputting the indicated value of the indicator 4 on the control panel 1, and an analysis result and the like are displayed. It comprises a CRT 8 for operation, a keyboard 9 for inputting data and operator's commands, and a touch panel 57.

In general, in a plant simulator, the surface of the control panel 1 often has the same shape as that used in an actual plant in order to value the realism. However, unlike a control panel of an actual plant, an internal circuit such as a relay sequence does not exist because it is simulated by software of the computer system 50. In recent years, the control panel 1 of an actual plant tends to be computerized. In this case, a digital input device 54, a digital output device 55 or an analog output device 56 is provided between the control panel 1 and the computer system 50. The number of cases in which data is transmitted by the data transmission device 58 without connection is also increasing.

With this configuration, an instructor (instructor) inputs an accident simulation setting request 10 to the accident simulation setting means 11 using the keyboard 9 or the like in addition to the normal operation, so that the accident simulation setting means 11 simulates the plant dynamic characteristics. An accident to be generated in the means 5 is set, and the accident occurrence state is simulated by the plant dynamic characteristic simulation means 5. Then, the accident occurrence state simulated by the plant dynamic characteristic simulating means 5 is once written in the process data file 6. The contents written in the process data file 6 are displayed on the indicator lamp 3 on the control panel 1, the indicator 4 and the CRT 8 as in the normal operation.

Next, an example of the operation of the plant dynamic characteristic simulation means 5 will be described with reference to the flowchart of FIG.

First, the state of the operation switch 2 on the control panel 1 is input by the digital input device 54 (process 4).
01). A relay sequence (logic) simulation is performed based on this change in the switch state, and it is determined whether or not the operation performed by the operator is valid (process 40).
2). If the logic condition is satisfied in this processing, the characteristics of the operating device (actuator) such as the pump and the valve are simulated, and the ON / OFF characteristics of the pump, the valve opening degree, etc. are calculated (processing 403). ). Based on the state of the operating device, for example, the dynamic characteristics of the process such as flow rate and pressure are calculated (process 404). The simulation of the dynamic characteristics is generally a physicochemical model so as to correspond to all operations and show 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 control panel 1 are output from the analog output device 56 and displayed on the indicator 4. (Process 405). Further, the calculated characteristics of the process are used not only for the display on the indicator but also for the relay sequence simulation calculation (process 406).
For example, when a certain process value is provided with an alarm value and an interlock operation setting value, depending on the state,
For the indicator light 3 on the control panel 1, a digital output device 55
Then, digital output is performed, and the indicator lamp 3 is turned on / off (process 407).

The relay sequence simulation is repeated until the simulation is completed and the plant becomes stable (process 408). That is, when the relay sequence operates and the actuator such as the valve operates (including the operation by the protection interlock) according to the calculation result of the process characteristic, the related dynamic characteristic simulation is performed again.

[0014]

However, as described above, in the conventional plant simulation device, in addition to the simulation of the plant state at the time of starting and stopping, the plant state at the time of an accident occurs mainly for the purpose of operation training. However, it was not possible to use it for the purpose of analysis support by simulating the characteristics different from the actual machine.

That is, in the conventional plant simulation device,
Its main purpose is operation training, and since it is important to have the same operation and response as an actual machine (real-time nature), a comprehensive simulation target including plant dynamics, interlock logic, closed-loop control system, etc. The behavior of the plant was faithfully simulated, and it was not possible to simulate the characteristics different from the actual machine.

For this reason, firstly, for example, in order to operate under conditions not present in the actual machine, the operation is performed excluding the interlock conditions existing in the actual machine, its behavior is analyzed, and the device characteristics of the actual machine are changed. It could not be used for the purpose of analysis support such as driving and analyzing its behavior.

Secondly, in recent years, since it is necessary to complete the operation training before starting the operation of the actual machine, the number of cases in which a plant simulator is manufactured several years faster than the actual machine is increasing. There is a growing demand for effective use of the plant simulator for multipurpose purposes such as analysis support, etc.

Thirdly, it is uneconomical to provide an analysis support simulator in addition to the conventional plant simulation device, and an analysis support simulator different from the conventional plant simulation device that faithfully simulates the actual device is used in the actual device. There is a possibility that the analysis support device will be completely different from the above.

As described above, there has been a demand for a plant simulation device that supports the improvement of an actual machine and the design of a new plant by the analysis support.

Therefore, an object of the present invention is to provide a plant simulator which can be efficiently used for various purposes by adding an analysis support function to the conventional operation training simulator.

[0021]

[0024]

According to the first aspect of the present invention, parameters relating to plant dynamic characteristics such as plant input condition equipment characteristics are changed or set by the analysis condition setting means. Therefore, the behavior of the plant is simulated by the dynamic characteristic simulating means under a condition that does not exist in the actual machine, and the result is stored in the analysis data file. Therefore, only the driving training simulator can support various purposes by changing various analysis conditions.

Therefore, it is easy to analyze the analysis data of the plant multiple times,
And it will be efficient.

According to the invention of claim 3, in addition to the invention of claim 2, the parameters relating to the dynamic characteristics of the plant can be time-series data. Therefore, the use of analysis support is further expanded.

[0027]

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

FIG. 1 is a block diagram of a plant simulation device showing a first embodiment of the present invention. In the figure, the same parts and corresponding parts as those in FIG. In the plant simulation device 17 of this embodiment,
In addition to the configuration of the conventional plant simulation device shown in FIG. 23, an analysis condition setting means 13, an analysis data storage means 14, an analysis data file 15 and an analysis result display means 16 are newly provided.

In the figure, the analysis condition setting means 13 is
The analysis condition is given to the plant dynamic characteristic simulating means 18, and the plant dynamic characteristic simulating means 18 simulates the plant behavior under the given analysis condition, and then writes this to the process data file 6. The analysis data storage means 14 extracts the process data file 6 according to the analysis condition set by the analysis condition setting means 13 and stores it in the analysis data file 15 for each analysis condition. The analysis result display means 16 displays the analysis results stored in the analysis data file 15 on the control panel 1 or C.
It is displayed on the RT8 in a form that is easy to see. In addition,
The plant simulation device shown in FIG. 1 has the same configuration as the hardware shown in FIG.

The analysis data file 15 will be described in detail with reference to FIG.

In this embodiment, the results obtained by operating a plurality of times under a plurality of analysis conditions can be individually managed. In the analysis data file 15, storage areas A are formed one by one corresponding to such analysis conditions.
In each storage area A, B0 corresponding to the analysis condition is
To Bn areas and C0 to Cn areas corresponding to the analysis results are formed.

In the figure, "analysis data identification number" is
The “analysis data comment information” is a number indicating which analysis data file 15, and the comment information associated with this is, for example, “change of piping coefficient at startup”.

Areas B0 to B corresponding to the analysis conditions
“Analysis condition set point identification number” of n is an identification number indicating which analysis condition is changed to the plant dynamic characteristic simulation means 18, and “analysis condition set point name” is, for example, “XX system pipe diameter or the like”. Is the name of. “Calculation condition (before setting)” is the process value that indicates what value was before the analysis condition set point was changed, and “Calculation condition (after setting)” was what value the above analysis condition set point was It is a process value that indicates whether it has been changed to.

Areas C0 to C corresponding to the analysis results
The “analysis result storage point identification number” of n is the identification number of the process point designated to be stored by the operator among the calculation results when the above analysis conditions are given, and the “analysis result storage point name” is, for example, XX This is the name of piping pressure. The "sampling time" is the sampling time of the data designated by the operator, and the "save start time" and "save end time" are the start time and end time thereof. The “analysis result data” is time series data of process values indicated by the analysis result storage point identification number.

With the above configuration, first, the operator outputs the analysis condition setting request 12 to the analysis condition setting means 13 by a predetermined operation using an input device such as a keyboard or a mouse, and activates the analysis condition setting process. When the analysis condition setting process is activated, the analysis condition setting screen is displayed on the CRT 8 as shown in FIG. 4 (process 101) as in the flowchart showing an example of the analysis support function process of FIG.

In this display screen, the display a shows the title of the display screen, and the display b shows the analysis data identification number indicating which analysis data file 15 and the input part of the analysis data comment. In addition, the display c is the identification number (PI
D) and the changed value [calculation condition (after change)] are shown in the input section, and the display d is the identification symbol (PID) of the analysis data to be saved.
And the sampling time, storage start, and end time input fields.

The operator inputs the analysis conditions to the above-mentioned input sections by using the keyboard 9 or the like (process 101). First, on the display b, the operator inputs an analysis data identification number indicating which analysis data file 15. If the analysis data identification number you entered is already in use, you will be warned by an error message. Then, in the "analysis data comment information", comment information,
For example, "change piping coefficient at startup" or the like is input.

In the display c, the "analysis condition set point identification number" indicating which analysis condition is to be changed is input to the plant dynamic characteristic simulation means 18. As a result, the corresponding "analysis condition set point name", for example, the name of the XX system pipe diameter, etc., is displayed, and in [Calculation condition (before change)], the A process value is displayed indicating whether the value was similar. Then, the operator refers to these values and inputs a process value indicating what value the above-mentioned analysis condition set point has been changed to [calculation condition (after change)].

Further, as the “analysis result storage point identification number”, the identification number of the point to be stored in the calculation result when the above analysis conditions are given is input. As a result, for example, a name such as XX piping pressure is displayed as the "analysis result storage point name". In addition, the operator is "sampling time"
As the sampling time of the analysis result data to be saved,
Enter the "save start time" and "save end time".

The above description is for the case where the data storage amount is limited, and when the data storage device has a large capacity, all the calculation results are displayed without specifying the analysis result storage point and the sampling time. It is also possible to save. The input analysis conditions are transmitted by the analysis condition setting means 13 to the plant dynamic characteristic simulation means 18, and the plant dynamic characteristic simulation means 18 simulates the plant dynamic characteristics based on the transmitted analysis conditions. For example, in order to operate under conditions that do not exist in the actual machine, the operation is performed by excluding the interlock conditions stored in the actual machine and the behavior is analyzed, or the machine characteristics of the actual machine are changed and the behavior is analyzed. A simulation of the plant dynamic characteristics such as analysis is performed (Process 10).
3).

Specifically, as shown in FIG. 5, the plant dynamic characteristic simulating means 18 when the analysis conditions are set is different from the conventional plant dynamic characteristic simulating means 5 shown in FIG. This is to add a determination process (process 501) and an analysis condition setting process (process 502) whether or not analysis condition setting is performed after step 401). When a parameter that does not exist in the actual machine is set as the analysis condition by the processing means as a characteristic of the process, the dynamic characteristic simulation (processing 404) is performed using the parameter, and as a result, the relay sequence is calculated by the calculated process value. When is operated, the relay sequence can be simulated under different conditions from the actual machine. Since the other points are the same as those described with reference to FIG. 25, description thereof will be omitted.

The result is temporarily stored in the process data file 6, but is saved by the analysis condition setting means 13 as the analysis data file 15 in the file format shown in FIG. 2 for each analysis condition (process 104). . Then, the analysis data once saved is used as the analysis result display means 1.
6, the analysis result is displayed on the control panel 1 and the CRT 8 in a graph display format or a system diagram format, for example, as shown in FIGS. 6 to 9 (process 105).

Here, in FIG. 6 described above, the PH concentration 42X of the solution A when the concentration X of nitric acid 41X is added at the time t0.
7 shows changes in the PH concentration 42Y of the solution A when the nitric acid 41Y having the concentration Y was added at the time t0, and FIG. 8 shows the nitric acid having the concentration Z at the time t1 after Δt from the time t0. The change of PH concentration 42Z of the solution A when 41Z is added is shown. In this case, the solution is mixed by a stirrer, and the chemical reaction proceeds slowly, so that the behavior is gentle.

These PH concentrations 42X, 42Y, 42Z
Are stored individually in the analysis data file 15, so that data with different analysis times can be displayed on the same graph as shown in FIG. In other words, normally only the data on the same time axis can be displayed on the same graph,
It is also possible to display calculation results under different analysis conditions, that is, data on different time axes in the same graph, even if the data storage timing is the same. This is because a normal plant simulation device has a function of being able to operate / analyze under the same conditions any number of times.

Normally, the data storage time is the starting point of the time axis, but if the display start time can be set as in the PH concentration 42X in FIG. 9, the analysis start timing will be set as in the PH concentrations 42Y and 43Z. It is possible to align and display the time axes on the basis of the different analysis data and the time T. The display of the analysis result data can be performed independently as an offline process without being affected by other processes even during use in driving training or the like. This is particularly effective in increasing the operation efficiency when it takes many hours for the behavior of the simulated plant to change and stabilize.

In this way, after simulating the plant behavior under the given analysis conditions, by displaying the results of the parameters that cannot be monitored during operation,
It can be efficiently used for various purposes such as analysis support.

Next, a second embodiment of the present invention will be described with reference to FIG.

The plant simulation device 17A of this embodiment is not limited to the plant simulation for the purpose of operation training only.
For example, plant input conditions, equipment characteristics,
Parameters related to plant dynamic characteristics such as interlock conditions and plant design conditions are changed and set to simulate plant behavior multiple times, and the results are processed into the required shape.
1 is different from that of FIG. 1 showing the first embodiment in that the analysis data processing means 22 for extracting the analysis results of a plurality of times under different operating conditions from the analysis data file 15 and performing the processing calculation is used. That is added.

Now, the processing of the analysis data processing means 22 will be described with reference to FIG.

First, the operator outputs the analysis data processing request 21 to the analysis data processing means 22 by a predetermined operation on the keyboard 9 or the like, and the analysis data processing process is activated. When this analysis data processing process is activated, an analysis data processing screen is displayed on the CRT 8 as shown in FIG. 12 (process 201).

FIG. 11 shows this display screen. The display e is a title of the display screen, and the display f is an input part of a display start analysis data identification number for designating which stored analysis data is to be displayed. Shows. Further, the display g shows an input section for inputting the analysis data identification number, the analysis data storage point identification number (PID), and the arithmetic expression for processing the analysis data while referring to the display f.

The operator inputs the editing and processing conditions to these input sections using the keyboard 9 or the like (process 20).
2). First, on the display f, the operator inputs the display start analysis data identification number and specifies the stored data to be displayed. The parameters displayed on this display f are the same as those described with reference to FIG.

Then, in the display g, the processing conditions are input with reference to the display f. The arithmetic expression is expressed by the arithmetic elements A, B, C, D and the operator. As the operator, a general arithmetic operation such as four arithmetic operations, 1 og, etc. can be used. As the calculation element, the stored analysis data can be designated by the analysis data identification number and the analysis result storage point identification number, or a numerical value such as 2.28 can be freely used.

When the processing conditions are input, processing calculation is performed (process 203). The result is previously saved again as an analysis data file 15 in the file format shown in FIG. 2 for each analysis condition (process 204). The stored analysis data after processing is displayed on the control panel 1 and the CRT 8 by the analysis result display means 16 in the same manner as described above, as shown in FIGS. Is displayed. For example, by this processing, it is possible to perform a ratio of parameters, a rate of change, a normalized display, and the like.

Here, FIG. 13, FIG. 14 and FIG. 15 are obtained by processing parameters calculated in different unit systems into one unit system by simple calculation. For example, both the pressure A (atm) 61 and the pressure A (Mpa) 61X have the relationship of the following expression (1).

[0056]

## EQU1 ## 1 atm = 0.01325 Mpa …………………… (1)

Therefore, if the analysis data processing means 22 is executed using the equation (1), the pressure B (Mpa) 61Y is obtained.
And can be compared on the same graph as shown in FIG.

Similarly, FIG. 16 shows the difference 62 between the pressure A (Mpa) and the pressure B (Mpa) which cannot be monitored in operation, and FIG. 17 shows the change rate 63 of the pressure A (Mpa) 61X, respectively. It is displayed after calculation by the processing means 22. It should be noted that although the processing process by simple calculation has been described as an example here, an optional program is created,
It is also possible to perform complicated calculations.

FIG. 18 is an example showing a display after processing when the component Z is represented by a function of the component X and the component Y.

In this example, the mass 64 of the constituent Y in the solution A and the mass 65 of the constituent Y in the solution B are mixed and chemically reacted to each other. ).

[0061]

[Equation 2] Z = F (X, Y) ……………… (2)

In the case of the above equation (2), it is a result of displaying the mass 66 of the constituent element Z after calculating Z by the analysis data processing means 22.

In this way, after simulating the plant behavior a plurality of times under the given analysis conditions, the results of parameters that cannot be monitored during operation are processed into the required form, and the results are processed. By displaying it, it can be efficiently used for multipurpose purposes such as analysis support purpose.

Next, a third embodiment of the present invention will be described with reference to FIG.

The plant simulation device 17B of the present embodiment is not limited to the plant simulation only for the purpose of operation training, but also includes, for example, plant input conditions, device characteristics, interlock conditions, plant design conditions, etc. which are not found in actual machines. The parameters relating to the plant dynamic characteristics are given to the plant dynamic characteristics simulating means 18 as time-series data, and after simulating the plant behavior a plurality of times, the results can be processed into a required form and displayed. The difference from 10 is that a time series data output means 32 for outputting time series data to the plant dynamic characteristic simulation means 18 based on the data of the analysis data file 15 is added.

In the plant simulation device 17B, the time series data output means 32 performs the processing shown in FIG. 20 when outputting the time series data.

First, the operator outputs the time-series data output request 31 to the time-series data output means 32 by a predetermined operation on the keyboard 9 or the like, and the time-series data output processing is started. When this time series data output process is activated, a time series data output condition screen is displayed on the CRT 8 as shown in FIG. 21 (process 301).

FIG. 21 shows this display screen.
The display h shows the title of the display screen, and the display i shows the input section of the display start analysis data identification number that specifies which stored analysis data is to be displayed. Further, the display j is an analysis data identification number for outputting the stored analysis data as time-series output data, an analysis data storage point identification number (PID), an output cycle, an output start time, with reference to the display i. The input part of is shown.

The operator inputs the analysis conditions to these input sections using the keyboard 9 or the like (process 302). The operator inputs the display start analysis data identification number on the display unit i and designates the saved data to be displayed. The parameters displayed on the display unit i are the same as those described with reference to FIG.

Subsequently, in display j, referring to display i, the analysis data identification number of the analysis data to be output as time series data and the analysis data storage point identification number (PI
D), output cycle, and output start time are input. In this case, the output cycle does not necessarily have to be the same as the sampling time displayed on the display i, and a value that is an integral multiple of the sampling time can be set. Similarly, the output start time does not have to be the same as the save start time displayed on the display i, and can be set if the time is after the save start time.

Next, required time series data is extracted from the analysis data file 15 under the input time series data output conditions (process 303). As the time-series data, data obtained by processing the analysis data shown in the second embodiment can also be used. Then, the extracted time-series data is given to the plant dynamic characteristic simulating means 18 as time-series data in a certain constant output cycle according to the previously set time-series data output condition (process 304).

As a result, the plant dynamic characteristic simulation means 1
In 8, the plant dynamic characteristic calculation is performed by the given time series data, and the result is the process data file 6 and the analysis data storage means 1 in the same manner as described above.
4, analysis data file 15, analysis data processing means 22
Processed and stored by. The stored analysis data after processing is displayed by the analysis result display means 16 on the control panel 1 and the CRT 8 in a graph display format, a table format, a system diagram format, etc., as shown in FIG.

By this time-series data output processing, it is possible to display the analysis result given the analysis condition of the time-series data, instead of the constant analysis condition as in the first embodiment. For example, as shown in FIG. 22, it is possible to show a change in the PH concentration 68 of the solution A when the inflow amount 67 of nitric acid having the concentration X is added as time series data. In this way, by giving time-series data as analysis conditions and simulating the plant behavior multiple times, even for parameters that cannot be monitored during operation, process the results into the required form and display the results for analysis. It can be efficiently used for various purposes such as support purposes.

[0074]

As described above, according to the present invention, the means for supporting the analysis of the plant simulator for simulating the plant behavior is provided. It is possible to change and set parameters relating to plant dynamic characteristics such as plant input conditions that are not included in the above. As a result, it is possible to obtain an effect of being efficiently used for a multipurpose use such as an analysis support purpose.
