Description

{High Risk Inducible Task Evaluating System And Evaluating Method}

The present invention relates to a method and apparatus for repairing and maintaining various plant facilities such as a nuclear power plant, a hydroelectric power plant, a steel plant, a chemical plant, etc. (hereinafter, simply referred to as "operator" And a method for analyzing a high risk inducible job.

Various plant equipments such as a power plant and a chemical plant are composed of a mutual organic system in which a plurality of complex and various apparatuses and facilities are systematically connected to each other and a minor fault of any one of them constitutes an output Sometimes, however, it leads to a trip of the equipment itself.

In order to prevent such accidents, the plant facilities regularly implement maintenance plans for inspection, testing, maintenance and replacement of parts, etc., in each division or system of the facility, The maintenance may be performed irregularly.

In order to perform such maintenance, procedures are normally prepared for each division or system, or work order, work process, etc., and the operation staff performs inspection, test, maintenance, and maintenance according to this procedure.

In such an operation such as checking, an erroneous operation of erroneously operating a part other than a normal operation object due to the carelessness of the operator is often generated, and an accident caused by erroneous operation does not stay in a simple safety accident, It may lead to a major accident ranging from a decrease in the overall system output to a complete shutdown of the system. Examples of the operation in which erroneous operations frequently occur include erroneous operation, miswiring, and erroneous separation of various switches, valves, various communication cards, or various cables (hereinafter, simply referred to as "switches").

Therefore, in order to prevent such accidents in advance, in general, the person in charge of the job in charge of the job is required to perform a task for the entire worker before the work, I will give advance education about possible accidents.

On the other hand, it is already well known that many of the incidents and accidents occurring in large plant facilities such as nuclear power plants are human accidents, or talent.

These switches are arranged concentrically on a control panel such as a central control room, and for example, There are many cases in which a plurality of switches or the like, which perform different functions as shown in the left side of Fig.

Therefore, if a wrong operation of various switches or the like due to an operator's mistake is made, the operation process of the whole equipment is greatly affected. In addition, since the system may be stopped or a case may cause a great risk of explosion, And is doing its best to prevent human error such as misoperation through periodic training.

However, it is not possible to guarantee complete safety by the training of the operators. Therefore, it is necessary to pre-simulate the effect of the operation of the switch on the output of the facility by using the heat output code, System is required.

In response to this demand, Patent Document 1 filed by the applicant of the present invention for analysis of a mis-selectable pattern such as various switches on a control panel that may occur during operation of a power plant or the like is currently undisclosed.

1, a high-risk inducible job analysis apparatus 100 according to a preferred embodiment of the present invention includes a maintenance management unit 110, a mis-selection analysis unit 120, and a mis-selection probability calculation unit 130 A performance evaluation unit 140, and a database 150. [

Here, the false selection probability calculation unit 130 is not essential to the system of the present invention, and may be omitted if necessary.

The maintenance management unit 110 manages regular or irregular maintenance plans for the inspection, test, maintenance or maintenance of the power plant, or other equivalent operations (hereinafter, collectively referred to as "inspection"), To this end, a daily schedule or a day-by-day schedule is stored in the database 150 in the form of a scheduler, and the scheduler includes a procedure including check points, procedures, inspection and maintenance instructions and other precautions required for each check Is stored.

In addition, the maintenance management unit 110 includes a user interface (not shown) that can manage the schedule such as the maintenance of the power plant, and the operating personnel can establish or modify the maintenance plan or the like using the interface, , A predetermined schedule can be selected, and a procedure corresponding to the selected schedule can be browsed.

As shown in FIG. 2, the scheduler for maintenance includes, for example, items to be performed for each date (5/1, 5/1, ..., 5/20) (periodic test 01, The periodic test 99) is written in correspondence with each date, and a procedure corresponding to the specific check item is written in the lower part, and the detailed procedure (1.1, 1.2, 1.3, ... ), And contents corresponding to this detailed procedure are described.

For example, if a driver of a power plant connects to the maintenance management unit 110 through a user interface and selects periodic test 2 on May 2, the scheduler performs a detailed procedure to be performed in the scheduled period 2 scheduled on May 2 Procedures 2.1, 2.2, 2.3, ... Along with the contents corresponding to each detailed procedure.

However, the maintenance management unit 110 may display the selected scheduler by a display device such as a computer monitor, or output it to a paper by a printer or the like, or by using a combination of both, .

The erroneous selection analysis unit 120 calls the image information on the specific procedure of the work point corresponding to the specific inspection item of the specific date of the procedure selected from the maintenance management unit 110 by the operation staff in the database 150, Generates an erroneous selectable pattern that may occur in the inspection, maintenance, or other operation process of the corresponding inspection item from the image information, and stores the generated erroneous-selectable pattern in the database 150 in correspondence with the corresponding procedure.

Specifically, the mis-selection analysis unit 120 extracts the individual switch coordinates on the control panel corresponding to the specific procedure, for example, using the image information of each work point stored in the database 150, Analyze individual switch coordinates to extract mis-selectable switch information.

Here, the switch that can be selected by mistake may be a switch adjacent to the switch that normally needs to be normally operated, and the mis-selection analyzer 120 extracts information on the mis-selectable switch together with the switch to be normally operated.

For example, in the image information of the control panel as shown in FIG. 4, for example, if the switch to be normally operated to perform the procedure 2.1 for the periodic test 2 is SW V / V-123 in FIG. 3, The left and right SW 1, 2, 3, and 4 may be switches having a large selection probability.

The generation of the erroneously selectable pattern by the erroneous selection analysis unit 120 can be performed, for example, by the method described in Patent Document 1, and the erroneously selectable pattern generation method by the erroneous selection analysis unit 120 itself Is not a subject of the present invention, and therefore, a detailed description thereof will be omitted.

In the above description, the possibility of mis-selection of the switch is described as an example of the mis-selectable pattern, but the present invention is not limited thereto. For example, misoperation of various wirings as shown in Fig. 5, Selection, erroneous replacement, or erroneous operation of various kinds of valves as shown in Fig.

The erroneous selection probability calculation unit 130 calculates the erroneous selection probability for each of the switches, for example, with respect to the erroneous selectable pattern generated by the erroneous selection analysis unit 120. [ For example, the m-HRA method described in the non-patent document 1 can be used. The error probability calculator 130 can calculate the probability using the above- , The detailed method of calculating the probability of false selection is not a subject of the present invention, and a detailed description thereof will be omitted here.

The calculation of the erroneous selection probability by the erroneous selection probability calculation unit 130 can be omitted as necessary as described above.

The power station performance evaluation unit 140 may include a mis-selection probability calculation unit 130 for each of the mis-selectable patterns analyzed by the mis-selection analysis unit 120, specifically, for each of the mis-selectable switches, for example, , It is necessary to operate the SW V / V-123, for example, as in the case where the SW 1 is erroneously operated due to the mistake of the operator, by referring to the erroneous selection probability calculated by the erroneous selection probability calculation unit 130 The effect of the erroneous operation on the entire power plant is simulated for each selectable pattern, and the result is displayed.

For example, the method described in Patent Document 2 can be used as a simulation method of the influence on the overall power output of the power plant by the performance evaluating unit 140 for each erroneous selectable pattern, and a specific simulation Since the method is not the subject of the present invention, a detailed description of the method is omitted here.

4 is a diagram showing an example of a result of simulation performed by the performance evaluation unit 140 on the influence on the output of the entire power plant when the switch of the main control panel is erroneously operated.

As shown in FIG. 4, the switch to be normally operated in the procedure 2.1 is the device number PM08-CA-HS-007, and the mis-selectable switch analyzed by the bad selection bad selection analysis unit 120 is the device number PM08-CA -HS-006, device number PM08-CW-HS-147, device number PM08-CA-HS-008 and device number PM08-CA-HS-014. The power output of the power plant is 1019.004 when the device number PM08-CA-HS-007 is operated normally. The increase / decrease of the output is 0.00%, ie the output does not increase or decrease. In case of erroneous operation of the numbers PM08-CA-HS-006 and PM08-CA-HS-008, the output of the power plant is 1019.004 and the increase / decrease of the output is 0.00% In the case of an operation of 147, a large accident that the power plant trips occurs, and the equipment number PM08-CA-H In the case of erroneous operation of S-014, the output of the power plant is 981.3157, and the output of the power plant is reduced by 3.70% if the output is increased or decreased by -3.70%, that is, when the switch of the device number PM08-CA-HS-014 is erroneously operated .

As shown in FIG. 5, the terminal to be operated in the procedure 2.2 is the device number DEMO-CABLE-001, the device number DEMO-CABLE-002 and the device number DEMO-CABLE- As a result of calculating the influence of the performance evaluating unit 140 on the entire power plant due to the erroneous operation for each of the erroneous selectable patterns, the power output of the power plant was reduced by 3.24% at the time of erroneous operation of the apparatus number DEMO-CABLE-003 have.

In FIG. 6, the output of the power plant is reduced by 1.87% at the time of erroneous operation of the communication number DEMO-CARD-003 of the communication card and by 2.95% at the time of erroneous operation of the device number DEMO-CARD- In low-pressure turbine stop valve, 1.87% in case of wrong operation of DEMO-SWITCH-002, 3.19% in case of wrong operation of DEMO-SWITCH-003 and 2.09% in case of wrong operation of DEMO-SWITCH-004 And the output of the power plant is lowered.

The performance evaluation unit 140 displays the simulation result as output increase / decrease together with the size of the power output of the power plant as shown in FIG. 4-7. In addition, the range of influence of mis- . ≪ / RTI > This is also specifically described in Patent Document 2, and a detailed description thereof will be omitted here.

When the system of the present invention includes the erroneous selection probability calculation unit 130 and the erroneous selection probability calculation unit 130 calculates the erroneous selection probability for each switch in the specific procedure, The unit 140 may also display the false selection probability calculated by the false selection probability calculation unit 130 at the same time.

The performance evaluating unit 140 may display the evaluation result for each of the erroneous-inducible patterns by increasing or decreasing the output and the output, and may select the high-risk inducible job based on the evaluation result.

The criterion for selecting a high risk inducible job can be determined, for example, by a method in which the output increase / decrease of the power plant is out of a predetermined range or the case where the power plant can trip can be selected as a high risk inducible job. It is also possible to use, for example, a method of displaying a high-risk inducible job in a specific color so as to be distinguishable from other jobs in displaying the evaluation result as shown in FIG. 4-7.

The high-risk triggerable job analysis apparatus of the present invention may further include an output unit (not shown), and the output unit may display the simulation result by the performance evaluation unit 140 using a display device such as an LCD panel The display device may be any display device such as a monitor, a portable terminal, or a mobile phone installed in a main control room or the like, for example .

The database 150 stores various data necessary for the practice of the present invention, such as the daily scheduler, a system diagram of the power plant, and the like, and also stores the results of analysis, calculation, and evaluation performed by each section of the present invention .

As described above, the result of the final simulation according to the present invention can be used as an educational material for the operating personnel prior to the work such as the test or maintenance of the power plant, so that the attention can be given to the operating personnel. Further, It is possible to prevent an accident such as a stoppage of the power plant or a decrease in output due to a human error of the inverter.

In addition, by displaying the range of influence of the misoperation of the specific switch on the system of the power plant with the system diagram, it can be utilized as the data that can identify the cause of the specific failure of the power plant.

Next, a method for simulating a high-risk inducible job by the system of the present invention will be described with reference to FIG. FIG. 8 is a flowchart illustrating a procedure for simulating a high-risk inducible job according to the present invention.

First, when the high-risk inducible job analysis apparatus 100 of the present invention is operated, the maintenance management unit 110 reads and displays the scheduler as shown in FIG. 2, for example, from the database 150.

Next, in step S1, the user confirms whether a schedule such as an inspection corresponding to a desired date exists in the scheduler. As a result of the confirmation, if there is no plan on a specific date (step S1 = No), the process ends. If there is a plan (step S1 = Yes), the process proceeds to step S2.

Next, in step S2, a job corresponding to the date is selected. For example, if May 2 is selected in step S 1, the periodic test 2 is scheduled on May 2 in the example of FIG. 2, so the user selects periodic inspection 2 as the job. At this time, in the example of the scheduler of FIG. 2, there is only periodic test 2 on May 2, but there may be two or more different schedules on the same date depending on the case. In this case, when the user selects a schedule do.

Next, in step S3, a procedure corresponding to the job selected in step S2 is selected. For example, in FIG. 2, since the procedure corresponding to the periodic test 2 is 02, the user selects the procedure 02. If the procedure 02 is selected, the maintenance management unit 110 performs the procedure corresponding to the periodic test procedure number 02 in Fig. With the contents corresponding to each procedure.

Next, in step S4, it is confirmed whether there is an existing evaluation result on the procedure included in the selected procedure.

As described above, the performance evaluation unit 140 stores the evaluation results in the database 150 for each of the procedures for which evaluation has been performed. Therefore, if the performance evaluation unit 140 previously performed the simulation for the specific procedure It is natural that the evaluation result is stored in the database 150.

Specifically, for example, in the procedure corresponding to the procedure number 02 in FIG. 2, there is a history of the simulation previously performed for the procedures 2.1, 2.2 and 2.3, and the procedure 2.1 and 2.2 in the case of the procedure 2.3, , In step S3, the maintenance management unit 110 judges that there is a history of simulation performed previously in procedures 2.1 and 2.2 in the procedure corresponding to the procedure number 02, and that there is no previous history of the simulation in the procedure 2.3 Can be displayed.

If there is an existing evaluation result for each procedure in step S4 (step S4 = Yes), the maintenance management unit 110 reads out and loads the existing evaluation result from the database 150, and if there is no existing evaluation result, .

Here, step S4 is not an essential step, and may be omitted. That is, in step S4, the existing evaluation results are loaded for a plurality of procedures included in the selected procedure, and the process proceeds to step S5 only when there is no existing evaluation result. However, The steps S6 and thereafter may be executed for all procedures irrespective of the result. However, in the case of omitting step S4, the load of the simulation according to the present invention may increase, and thus the time required for the evaluation may be longer.

In step S5, the erroneous selection analyzing unit 120 generates a pattern capable of causing a human error, that is, an erroneous selectable pattern. The method of generating the erroneous selectable pattern is the same as described above, and the pattern generated in step S5 may be, for example, a pattern as shown in Fig.

If S4 is omitted, in step S5, an erroneous selectable pattern is generated for all the procedures included in the selected procedure.

Next. In step S6, the erroneous selection probability calculation unit 130 calculates the human error occurrence probability for each pattern generated in step S5, specifically, the erroneous selection probability for each erroneous selectable pattern.

As described above, the calculation of the false selection probability by the false selection probability calculation unit 130 in step S6 may be omitted. In this case, the process directly proceeds to step S7 in step S5.

In step S7, the performance evaluating unit 140 refers to the erroneous selectable patterns generated in step S5, specifically, for each of the erroneously selectable switches, for example, when the step S6 is performed, Although it is necessary to operate the SW V / V-123 of FIG. 3 in a specific procedure, for example, when SW 1 is erroneously operated due to a mistake of the operating personnel, The effects are simulated and evaluated.

Next, in step S8, the high-risk inducible job is selected based on the simulation result in step 7. [

Next, in step S9, it is determined whether there is a further process to be evaluated. If there remains, the process returns to step S5 to repeat the subsequent steps. If there is no more, the process goes to step S9 to display the evaluation result. The evaluation result is stored in the database 150 and then the process ends.

Details of the evaluation method, the display method, and the display content performed by the performance evaluation unit 140 in steps S7, S8, and S9 are the same as those described in the performance evaluation unit 140 described above. do.
