DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[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, plant operators need only to perform normal operation smoothly. In addition, the ability to quickly perform a treatment when an abnormality occurs is required.
For this purpose, various plant simulators have been developed as devices for training plant operators, including simulators for operation training (simulators). Many of the plant simulators for operation training described above are configured to be able to simulate a plant state at the time of occurrence of an accident in addition to simulating a plant state at the time of starting or stopping.

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

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

In 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,
This calculation result is written to the process data file 6,
The contents of the process data file 6 are displayed on the display lamp 3, the indicator 4 and the CRT 8 by the process display means 7.

Here, FIG. 24 shows an example of a specific hardware configuration of the plant simulation apparatus shown in FIG.

[0007] The plant simulation apparatus is mainly composed of a control panel 1 provided with operation switches 2, indicators 3 and indicators 4 necessary for operation and monitoring, and a computer system 50. The computer system 50 converts each unit shown in FIG. 23 into software, stores the disk unit 51 as a program, a central processing unit 52 and a memory 53 for executing the unit, a memory 53 and a switch state on the control panel 1. A digital input device 54 for inputting, 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 analysis results are displayed. And 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 is often formed in the same shape as that used in an actual plant in order to value the sense of reality. However, unlike the control panel of the actual plant, there is no circuit such as an internal relay sequence because it is simulated by the software of the computer system 50. In recent years, the control panel 1 of the actual plant tends to be computerized. In this case, the digital input device 54, the digital output device 55, and the analog output device 56 connect the control panel 1 and the computer system 50. The number of cases where data is transmitted by the data transmission device 58 without connection is also increasing.

With this configuration, in addition to the normal driving operation, the instructor (instructor) inputs the accident simulation setting request 10 to the accident simulation setting means 11 using the keyboard 9 or the like, so that the accident simulation setting means 11 simulates plant dynamic characteristics. An accident to be caused 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 simulation means 5 is temporarily written to the process data file 6. The contents written in the process data file 6 are displayed on the indicator 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). Based on this change in the switch state, a relay sequence (logic) simulation is performed, 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 process, the characteristics of the operating device (actuator) such as a pump and a valve are simulated, and the ON / OFF characteristics of the pump, the opening of the valve, and the like are calculated (process 403). ). Based on the state of the operating device, for example, dynamic characteristics of the process such as flow rate and pressure are calculated (process 404). The simulation of the dynamic characteristics corresponds to every operation, and it is general to use a physicochemical model so as to exhibit the same characteristics as those of 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). The calculated process characteristics are used not only for display on the display meter but also for relay sequence simulation (step 406).
For example, if a certain process value is provided with an alarm value and an interlock operation set value,
A digital output device 55 is provided for the indicator light 3 on the control panel 1.
, A digital output is performed, and the indicator lamp 3 is turned on / off (process 407).

The simulation of the relay sequence 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 a valve operates (including the operation by the protection interlock) according to the calculation result of the characteristic of the process, the related dynamic characteristic simulation is performed again.

[0014]

However, as described above, in the conventional plant simulation apparatus, in addition to the simulation of the plant state at the time of start / stop and the like, the plant state at the time of occurrence of an accident is mainly used for operation training. Can be simulated, but cannot simulate characteristics different from those of the actual machine and can be used for analysis support purposes.

That is, in the conventional plant simulator,
The main purpose is operation training, and the realism (real-timeness) of the same operation and response as the actual machine is important, so a comprehensive simulation target including plant dynamic characteristics, interlock logic, closed loop control system, etc. The behavior of the plant was simulated faithfully, and it was not possible to simulate characteristics different from those of the actual machine.

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

Secondly, in recent years, it has been necessary to complete operation training before starting operation of an actual machine, so that the number of cases where a plant simulation apparatus is manufactured several years earlier than that of an actual machine has been increasing. There is an increasing demand not only for use but also for effective use of a plant simulation device for multiple purposes such as analysis support.

Thirdly, it is uneconomical to provide an analysis support simulator separately from the conventional plant simulation apparatus, and the conventional plant simulation apparatus and another analysis support simulator that faithfully simulate the actual machine use the actual machine. There is a possibility that the analysis support device will be completely different from the analysis support device.

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

Accordingly, an object of the present invention is to provide a plant simulator that adds an analysis support function to a conventional driving training simulator and can be used efficiently for various purposes.

[0021]

According to the present invention, there is provided a plant dynamic characteristic simulating means for calculating dynamic characteristics based on parameters such as input conditions and interlock conditions necessary for simulating a plant; A plant simulation which has a process data file for storing the operation result of the characteristic simulation means and a process display means for displaying the saved contents of the process data file on the display means, and simulates the behavior of the plant with respect to the operation of the plant. In the device,
An analysis condition setting means for changing various parameters set in the plant dynamic characteristic simulation means for analyzing the plant and setting these as analysis conditions, and a result calculated by the plant dynamic characteristic simulation means based on the analysis conditions Analysis data storage means for extracting the analysis data from the process data file and storing the analysis data in the analysis data file for each analysis condition, and analysis result display means for displaying the analysis data stored in the analysis data file on the display means. .

According to a second aspect of the present invention, an analysis data processing means for extracting the analysis data from the analysis data file and processing the analysis data into a required format in the first aspect of the invention is added.

According to a third aspect of the present invention, there is provided a time series output unit for outputting time series data to a plant dynamic characteristic simulation means in order to analyze a plant based on the time series data stored in the analysis data file. Data output means is added.

[0024]

According to the first aspect of the present invention, the parameters relating to the plant dynamic characteristics such as the input condition device characteristics of the plant are changed or set by the analysis condition setting means. For this reason, the behavior of the plant is simulated by the dynamic characteristic simulating means under conditions not present in the actual machine, and the results are stored in the analysis data file. Therefore, if only a driving training simulator is used, multi-purpose analysis support can be performed by changing various analysis conditions.

According to the second aspect of the present invention, in addition to the first aspect of the present invention, the result of simulating the behavior of the plant a plurality of times by the dynamic characteristic simulating means is processed into a required form and displayed. Therefore, it is easy to analyze the analysis data of the plant multiple times,
And it becomes efficient.

According to the third aspect of the present invention, in addition to the second aspect of the present invention, the parameters relating to the dynamic characteristics of the plant can be time-series data. Therefore, the use of the 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 simulator showing a first embodiment of the present invention. 23, the same parts and corresponding parts as those in FIG. 23 are denoted by the same reference numerals, and a duplicate description will be omitted. In the plant simulation device 17 of this embodiment,
In addition to the configuration of the conventional plant simulation apparatus 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 comprises:
The analysis conditions are given to the plant dynamic characteristic simulation means 18. The plant dynamic characteristic simulation means 18 simulates the plant behavior under the given analysis conditions, and then writes this in the process data file 6. The analysis data storage unit 14 extracts the process data file 6 according to the analysis condition set by the analysis condition setting unit 13 and stores the process data file 6 in the analysis data file 15 for each analysis condition. The analysis result display means 16 displays the analysis result stored in the analysis data file 15 on the control panel 1 or C
This is displayed in a form that is easy to see on the RT8. In addition,
The plant simulation device shown in FIG. 1 has the same configuration as the hardware shown in FIG.

Here, the analysis data file 15 will be specifically described with reference to FIG.

In the present embodiment, the result of a plurality of calculations 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.
Each storage area A has B0 corresponding to the analysis condition.
Bn and C0 to Cn areas corresponding to the analysis results are formed.

In the figure, “analysis data identification number”
This is a number indicating which analysis data file 15 is used, and the "analysis data comment information" is comment information attached thereto, such as "change of piping coefficient at startup".

The areas B0 to B corresponding to the analysis conditions
The “analysis condition set point identification number” of n is an identification number indicating which analysis condition is to be changed to the plant dynamic characteristic simulation means 18, and the “analysis condition set point name” is, for example, “xx system pipe diameter or the like”. Is the name of "Calculation condition (before setting)" is a process value indicating what the value was before the analysis condition set point was changed, and "calculation condition (after setting)" was what the analysis condition set point was. Is a process value indicating whether or not it has been changed to

The 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 saved 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 a name such as piping pressure. The “sampling time” is the data sampling time specified by the operator, and the “save start time” and “save end time” are the start time and the end time. The “analysis result data” is time-series data of the process value indicated by the analysis result storage point identification number.

In the above configuration, first, the operator outputs an analysis condition setting request 12 to the analysis condition setting means 13 by a predetermined operation using an input device such as a keyboard and a mouse, and starts the analysis condition setting process. When the analysis condition setting process is started, an analysis condition setting screen is displayed on the CRT 8 as shown in FIG. 4 as shown in a flowchart of an example of the analysis support function process of FIG. 3 (process 101).

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

The operator inputs an analysis condition to each of the above-mentioned input units using the keyboard 9 or the like (process 101). First, the operator inputs an analysis data identification number indicating which analysis data file 15 is displayed on the display b. If the input analysis data identification number has already been used, a warning is issued with an error message or the like. And "analysis data comment information" contains comment information,
For example, the user inputs "change of piping coefficient at startup".

In the display c, an "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. A process value indicating whether such a value was obtained is displayed. Then, the operator refers to these values and inputs a process value indicating what value the analysis condition set point has been changed in [calculation condition (after change)].

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

In the above description, the data storage amount is limited. When the data storage device has a large capacity, all the calculation results can be stored without specifying the analysis result storage point and the sampling time. It is also possible to save. The input analysis condition is transmitted to the plant dynamic characteristic simulation means 18 by the analysis condition setting means 13, and the plant dynamic characteristic simulation means 18 simulates the plant dynamic characteristic 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. Simulation of plant dynamic characteristics such as analysis is performed (process 10).
3).

More specifically, as shown in FIG. 5, the plant dynamic characteristic simulating means 18 at the time of setting the analysis conditions is different from the conventional plant dynamic characteristic simulating means 5 shown in FIG. After (401), a process of determining whether or not the analysis condition has been set (process 501) and an analysis condition setting process (process 502) are additionally provided. When a parameter that does not exist in the actual machine is set as a process characteristic as an analysis condition by this processing means, dynamic characteristics simulation (process 404) is performed using the parameter, and as a result, the relay sequence is calculated based on the calculated process value. , The relay sequence simulation can be performed under conditions different from those of the actual machine. The rest is the same as described with reference to FIG. 25, and a description thereof will not be repeated.

The result is temporarily stored in the process data file 6, but is stored 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 stored is transmitted to the analysis result display means 1.
6, the analysis result is displayed on the control panel 1 and the CRT 8 in the form of a graph or a system diagram, for example, as shown in FIGS. 6 to 9 (process 105).

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

These PH concentrations 42X, 42Y, 42Z
Are individually stored in the analysis data file 15, so that data having different analysis times can be displayed on the same graph as shown in FIG. In other words, usually only data on the same time axis can be displayed on the same graph,
As long as the data storage timing is the same, the calculation results under different analysis conditions, that is, data on different time axes can be displayed on the same graph. This is because a normal plant simulation device has a function of performing operation and analysis calculations under the same conditions any number of times.

Normally, the data storage time is the starting point of the time axis. However, if the display start time can be set as in the PH concentration 42X in FIG. 9, the analysis start timing as in the PH concentrations 42Y and 43Z. It is possible to align and display the time axis based on the different analysis data and the time T. The display of the analysis result data can be performed alone as offline processing without being affected by other processing even during use in driving training or the like. This is particularly effective in increasing operation efficiency when it takes 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, the results of the parameters that cannot be monitored during operation are displayed by displaying the results.
It can be efficiently used for various purposes such as analysis support purpose.

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

The plant simulator 17A of the present embodiment is not limited to plant simulation for operation training purposes only.
For example, plant input conditions, equipment characteristics,
After changing and setting parameters related to plant dynamic characteristics such as interlock conditions and plant design conditions, and simulating plant behavior multiple times, processing the results to the required form,
The difference from FIG. 1 showing the first embodiment is that the analysis data processing unit 22 that extracts a plurality of analysis results with different operating conditions from the analysis data file 15 and performs a processing operation is configured. That is the addition.

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

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

FIG. 11 shows this display screen. A display e is a display screen title, and a display f is a display start analysis data identification number for designating which stored analysis data is to be displayed. Is shown. A display g indicates an input unit for inputting an analysis data identification number, an analysis data storage point identification number (PID), and an arithmetic expression for processing the analysis data while referring to the display f.

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

Then, on display g, processing conditions are input with reference to display f. The operation expression is expressed by operation elements A, B, C, D and operators. As the operator, an arithmetic expression such as a normal four arithmetic operation, 1 log, or the like can be used. As the operation 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 used freely.

When the processing conditions are input, a processing operation is performed (step 203). This result is stored again as the analysis data file 15 in the file format shown in FIG. 2 for each analysis condition (process 204). The saved 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 with. For example, a ratio between parameters, a change rate, a normalized display, and the like can be performed by this processing.

Here, FIGS. 13, 14 and 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 equation (1).

[0056]

## EQU00001 ## 1 atm = 0.101325 Mpa (1)

Therefore, if the analysis is performed by the analysis data processing means 22 using the equation (1), the pressure B (Mpa) 61Y
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 during operation, and FIG. 17 shows the change rate 63 of the pressure A (Mpa) 61X. This is displayed after the calculation by the processing means 22. In addition, here, the processing using the simple calculation has been described as an example.
It is also possible to make 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 component Y in the solution A is mixed with the mass 65 of the component Y in the solution B, and the mass 66 of the component Z in the mixed solution C chemically reacted is expressed by the following equation (2). ).

[0061]

## EQU2 ## Z = F (X, Y) (2)

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

After simulating the plant behavior a plurality of times under the given analysis conditions in this way, parameters that cannot be monitored during operation are processed into the required form, and the results are processed. By displaying, it can be efficiently used for various 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 this embodiment is not limited to plant simulation for operation training purposes only. For example, plant input conditions, equipment characteristics, interlock conditions, plant design conditions, etc., which are not found in actual equipment. The parameters relating to the plant dynamic characteristics are given as time-series data to the plant dynamic characteristics simulation means 18 to simulate the plant behavior a plurality of times, and then the result is processed into a required form and displayed. The difference from 10 is that a time-series data output unit 32 that outputs time-series data to the plant dynamic characteristic simulation unit 18 based on the data of the analysis data file 15 is added.

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

First, the operator outputs a 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 process is started. When the time-series data output process is started, 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 indicates the title of the display screen, and the display i indicates the input section of the display start analysis data identification number for specifying which stored analysis data is to be displayed. The display j is an analysis data identification number, an analysis data storage point identification number (PID), an output cycle, and an output start time for outputting stored analysis data as time-series output data while referring to the display i. Is shown.

The operator inputs analysis conditions to these input units by 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 specifies the storage data to be displayed. The parameters displayed on the display unit i are the same as those described in FIG.

Subsequently, in the display j, referring to the display i, the analysis data identification number and the analysis data storage point identification number (PI
D), an output cycle, and an 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 it is possible to set an integer multiple of the sampling time. Similarly, the output start time does not need to be the same as the storage start time displayed on the display i, and can be set as long as the time is after the storage start time.

Next, necessary time-series data is extracted from the analysis data file 15 under the input time-series data output condition (step 303). As this 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 as time-series data in a certain output cycle according to the time-series data output condition previously set to the plant dynamic characteristic simulation means 18 (process 304).

Thus, the plant dynamic characteristic simulating means 1
At 8, the plant dynamic characteristics are calculated based on the given time-series data, and the result is the process data file 6 and the analysis data storage unit 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 on the control panel 1 and the CRT 8 by the analysis result display means 16 in a graph display format, a table format, a system diagram format, and the like as shown in FIG.

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

[0074]

As described above, according to the present invention, a means for supporting the analysis of a plant simulation apparatus for simulating plant behavior is provided. It is possible to change and set parameters related to plant dynamic characteristics, such as input conditions of a plant, which are not already available. As a result, there is obtained an effect that it can be efficiently used for various purposes such as analysis support purpose.
