Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant facility diagnostic apparatus for assisting facility diagnostics for grasping abnormal signs and the like of plant constituent facilities by a plant inspection and inspection performed as part of maintenance work in a power plant, for example.

[0002]

2. Description of the Related Art In equipment diagnosis in a power plant, a detector (sensor) is attached to main equipment to grasp the situation of each equipment, and diagnosis and monitoring are performed online in a central control room.

However, in a large-scale plant such as a power plant, it is not possible to monitor all the process data on-line enough to grasp the status of all facilities. I go to the vicinity of and check the condition of equipment (patrol inspection).

In particular, since the operation of the hydroelectric power plant is performed by remote control from the integrated control station,
On-site inspection work plays an important role in grasping the detailed situation of the equipment.

Generally, in this on-site inspection work, inspection inspection data is collected by handwriting according to check items on a recording sheet or by using a portable data input device such as a handy terminal to collect inspection inspection data.

The data collected in the field inspection work include not only the measured values read by the meters installed in the equipment, but also the conditions of each equipment and its surroundings, such as color, odor, and so on.
Although there is information that can be perceptually captured, such as sound, in patrol inspection work, the comparison of measured data with the threshold value unique to each data is the main, and it is based on the experience of patrol personnel. The situation of the equipment is grasped by comprehensive judgment taking into account various information.

As described above, the experience of the patrol officer is an important point in grasping the equipment status at the time of the patrol inspection. The current situation is that it depends on the situation judgment by.

Regarding equipment diagnosis, in recent years, it has been generally realized that a diagnosis rule is stored by using an electronic computer and the judgment of the equipment status is supported by taking in all process amounts required for equipment diagnosis.

[0009]

However, in general, in order to diagnose the equipment, it is necessary to take in all the necessary process amount, but it is aged as in an existing plant, for example, some hydroelectric power plants. In a plant with a large number of plants, it is difficult to install a new sensor to capture the process amount required for facility diagnosis from the economical point of view.Therefore, it is necessary to use the data at regular inspections. It was

Further, in a plant such as a hydroelectric power plant that operates unmanned, it is usual to be separated from the general control station which monitors the operation of the plant by several tens of kilometers. In such a plant, there is a restriction on the monitoring equipment that is permanently installed in the field due to the peculiarity of unmanned operation, and generally, the monitoring equipment used for facility diagnosis is installed at the general control station where maintenance personnel are present.

In such an environment, the patrol officers go to the site as patrol inspection work only in a cycle of several times a month, and in addition, some data is necessary for diagnosing the equipment. In normal inspection, it is not efficient to collect all the data that can diagnose the condition of the facility at all times, so we usually collect more necessary data after narrowing down the abnormal part. For this reason, it is necessary to revisit the operation control center after returning to the general control station, where it is necessary to reconfirm, and it may take a long time to go out again. Therefore, it was necessary to confirm the diagnosis result on site during the inspection work.

Further, the technician who actually carries out the inspection inspection work is not necessarily a skilled technician, and when a final situation judgment is required immediately such as in an emergency, the technician who is at the general control station distant from the site Since the technician could not judge the proper equipment status, the response could be delayed and a serious accident could occur.

The present invention has been made to solve the above-mentioned problems, and the experience and knowledge obtained by a skilled technician who has been engaged in equipment maintenance work for many years are stored in advance in an electronic computer to be used, whereby Not only is it possible to judge the equipment status regardless of the level, but it is also possible to check the details of the diagnosis being carried out by patrols at the site, and at the same time the diagnosis process can be performed at locations other than the site, such as the general control station where operation is monitored. By making it possible to check, including the facility engineers, a plant facility diagnosis function that has a facility diagnosis function so that even if a skilled technician is not on site, he / she can fully understand the current equipment status and give advice etc. to patrols. The purpose is to provide a device.

It is composed of a diagnostic data transmitting means 35 for transmitting.

Next, the operation of the plant facility diagnostic device having the above configuration will be described by taking the maintenance of the component equipment of the hydroelectric power plant as an example. When patrols go on-site inspection to grasp the condition of the components of the hydroelectric power plant,
Bring the portable inspection inspection data input processing device 1. First, an on-site patrolman uses the inspection data input means 11 to input the measured values of a meter or the like obtained by the on-site patrol inspection and the conditions around each facility, for example, judgment data such as “dirt” and “unpleasant odor”.

3 and 4 show inspection data input means 1
It is a screen at the time of data input by 1. At the time of data input, information such as the names of the inspection items that must be inspected is displayed in order according to a predetermined inspection route order so that the inspection person can easily input the measurement data. FIG. 2 is an example of a screen for inputting measurement values. On this screen, patrol inspection course name "A course" and patrol inspection order number "00

FIG. 3 is an example of a screen for inputting the judgment data of the equipment status. Similar to the screen shown in FIG. 2, the inspection inspection item name and the like are displayed on the screen. Besides that,
Since options such as "1. normal / 2. Abnormal" are displayed on the screen, selecting one of them will complete the input.

The patrol inspection data thus input is temporarily stored in the inspection data file f1.

When the patrol officer completes the patrol inspection of the hydroelectric power plant equipment along the patrol route once, the patrol officer displays the equipment status on the screen of the portable patrol inspection data input processing device 1 as shown in FIG. Request diagnostic execution by selecting diagnostic execution. The diagnosis execution request by the patrol officer is notified to the inspection data transmitting means 15 via the diagnosis execution requesting means 13.

When the inspection data transmission means 15 receives the diagnosis execution request from the diagnosis execution request means 13, the inspection data transmission means 15 has a portable inspection inspection data input processing device 1 in the hands of a patrolman at the site of the hydroelectric power plant, and a plurality of hydroelectric power generation devices. A line is connected by a transmission line 5 to a facility condition diagnosis processing device 3 installed in a plant control room where the plant is remotely operated, and the inspection inspection data in the inspection data file f1 is installed together with the diagnostic execution request signal. It is transmitted to the situation diagnosis processing device 3.

The inspection data receiving means 23 receives the inspection inspection data transmitted from the portable inspection inspection data input processing device 1 and creates the inspection data reception file f9 and at the same time stores it in the history data file f11 as history data. , And makes a diagnostic control request to the diagnostic control means 25.

In the inspection inspection data reception file f9, for example, as shown in FIG. 6, inspection inspection time, inspection inspection type, inspection inspection device name, inspection inspection item name, alarm limit value (upper limit Lower limit) ・ Measured value ・ Payment inspection data judgment result ・ Paper memos are recorded.

When the diagnostic control means 25 receives the diagnostic control request, it notifies the diagnostic means 27 of the facility diagnostic execution request, extracts the data required for the facility diagnostic from the inspection inspection data reception file f9, and the diagnostic means 27 Pass to.

The diagnosing means 27 receives the inspection inspection data together with the facility diagnosis execution request from the diagnosing control means 25 and makes a diagnosis. This is called primary diagnosis. In this primary diagnosis, the patrol staff collects the patrol inspection data collected by the patrol inspection and transmitted to the facility condition diagnosis processing device 3 for each patrol inspection item.
It is compared with the reference value data extracted from the reference value file f13, and it is determined whether the value is normal or abnormal.
The reference value data mainly refers to the upper limit value and lower limit value that are set in advance for each inspection inspection item. Further, the past data of the same patrol inspection item is searched and extracted from the history data file f11, and the transition of the values indicated by them to the present is trend-wisely confirmed to confirm whether or not the measured value of this time is normal.

The background of the equipment diagnosis executed in the diagnosis means 27 and the diagnosis result obtained by the diagnosis are as follows:
It is also displayed to the monitoring personnel in the plant control room via the display means 29. As a result, the supervisor (experienced technician) can confirm and grasp the status of plant equipment and the presence or absence of abnormal signs without going to the site.

FIG. 7 shows an example of a screen displayed to the plant supervisor. In FIG. 7, in the screen division 41,
The names and measurement values of the inspection items used for facility condition diagnosis and related data such as the upper and lower limits set for the inspection items are displayed. For measured values that exceed the upper and lower limit values that have been set, a warning is displayed by highlighting, such as changing the color. In the screen division 43, various information obtained during the process of performing the facility diagnosis, for example, when the measurement value of a certain inspection item is determined to be abnormal, the process leading to the conclusion, the determination criteria, the determination reason, and the like are generated. They are displayed in the order in which they were done. Also in this case, as in the case of the screen division 41, an item such as a color change is highlighted with respect to an item determined to be abnormal in the equipment diagnosis process. The screen division 45 is a screen that shows the judgment of the equipment device status issued by the equipment diagnosis by text. Further, the screen division 47 is a screen showing a method for taking a corresponding action when it is determined that the equipment has an abnormality. Also, 49 to 55 are buttons,
By selecting, the corresponding screen is displayed.

When the button 49 is selected, a trend graph as shown in FIG. 8 is displayed. This trend graph shows the change in the measured values used for equipment diagnosis from the past, and the measured values of multiple inspection items are 1
By comparing and displaying in one graph, it is possible to perform comparison comparison.

Reference numeral 51 is a button for requesting display of a related drawing. When selected, a plurality of screens as shown in FIG. 9 appear. The screen of 61 displays a simplified drawing of the equipment, and highlights the location diagnosed as abnormal. Reference numeral 63 shows a patrol inspection route map, and 65 shows a system diagram. With reference to these drawings, the plant monitor can grasp the configuration of the facility equipment on site.

When the button 53 for displaying a causal relationship diagram is selected, a causal relationship diagram as shown in FIG. 10 is displayed. The causal relationship diagram shows the relationship between some abnormal events that are assumed to be established by equipment diagnosis. An event such as a color change is highlighted with respect to the event that is determined to be established. Also,
By selecting the button 71 for matrix display on the screen, a matrix table summarizing the determination method of success / failure of each event as shown in FIG. 11 is displayed.

The plant monitor on the side of the equipment condition diagnosis processing unit 3 confirms the information obtained from the screens shown up to now and makes a comprehensive judgment, and as a result, conducts equipment diagnosis at the hydroelectric power plant site. If there is any advice to the patrolling staff, the advice input means 33 selects the advice input button 55 on the screen of FIG. 7 and inputs it in a word processor format as shown in FIG. The contents are the advice data file f
19 is stored.

When the equipment diagnosis processing is completed, the diagnosis means 27 stores the result in the diagnosis result data file f15. In addition, as a result of the diagnosis processing, if there is a re-payment inspection item for advancing further detailed diagnosis, the contents thereof are displayed on the display unit 31 and stored in the re-inspection item file f17 at the same time as the diagnosis result.

The detailed diagnosis referred to here is a threshold check of measurement data, that is, a diagnosis for pursuing the cause of an abnormality determined by the primary diagnosis, and a detailed check of the condition of the equipment required for that purpose. It refers to re-diagnosis based on the results obtained after requesting a patrol inspector from the patrol in the form of a question, and this is called secondary diagnosis. It is necessary for the secondary diagnosis to collect all the data necessary to execute the secondary diagnosis during the regular inspection work, because the number of inspection items becomes enormous and the work efficiency decreases. The inspection items are not included in the regular inspection items. In addition, the information necessary for secondary diagnosis is mainly obtained by patrols by the patrols, and it is difficult to add new sensors etc. In the embodiment, the abnormalities are narrowed down, and then the inspection of the periphery of the equipment is re-inspected to eliminate omission of the inspection, and the secondary diagnosis based on the data obtained by the inspection is performed to achieve high accuracy. Facility diagnostics can be performed.

FIG. 13 illustrates the structure of the re-inspection item file f17. The contents of the re-inspection item file f17 include the number, name, operation method, and options of the re-inspection inspection item, but here, the operation method is to collect data different from that collected by a regular inspection by an inspection person. To get it done
It is a text that summarizes the sampling method, for example, the method of measuring water volume and the method of measuring temperature.

A diagnosis result data file f15 storing the diagnosis result is created, and is also used for executing the detailed diagnosis (secondary diagnosis) and the advice data file f19 storing the advice input by the observer if necessary. A re-inspection item file f17 is created, and a diagnosis result transmission command and an advice input means 3 are issued from the diagnosis means 27.
When the advice transmission command is issued from 3, the diagnostic data transmission means 35 combines the diagnostic result data, the advice data, and the re-inspection item data extracted from these three files as diagnostic data and is portable in the hydroelectric power plant. It transmits to the inspection inspection data input processing device 1 via the transmission line 5.

The data sent via the transmission line 5 is the diagnostic data receiving means 1 of the portable patrol inspection data input processing device 1.
7, the contents of which are received by the diagnostic result reception file f
3, the advice reception file f7 and the re-inspection item reception file f5 are stored respectively. On the portable patrol inspection data input processing device 1 side, first, the diagnostic result received by the diagnostic data display means 21 is taken out from the diagnostic result reception file f3, and the content is displayed on the display unit 19. Also, if there is advice from the plant supervisor, the advice data is also displayed.

FIG. 14 is an example of a screen displayed on the display unit of the portable patrol inspection data input processing device. In this figure, the screen is divided into three, and screen division 81
, The plant equipment is roughly divided by system,
The diagnostic results are displayed for each. Here, the status of the equipment and equipment obtained by the equipment diagnosis performed by the equipment status diagnosis processing device 3 and, if it is determined that there is an abnormality in the equipment, the abnormal location and the like are displayed together with the diagnosis result. In the screen section 83, what kind of treatment must be taken by the patrol officer regarding the equipment that is diagnosed as abnormal in the screen section 81, and what must be done to prevent the recurrence. I'm instructing the patrol officer. In the screen section 85, the advice input by the monitoring staff to the patrol staff by the equipment status diagnosis processing device 3 in the plant control room is displayed.

While observing the screen displaying these diagnostic data, the patrol officer determines the condition of the equipment and equipment at the level of a skilled engineer, an appropriate coping method therefor, and the advice input by the plant supervisor on site. You can get it instantly.

By the way, what is displayed here is mainly the result of the primary diagnosis in which the threshold value of the measurement data is checked, and when the re-inspection item reception file f5 has been generated, the equipment devices are connected to each other. The contents of the re-inspection item reception file are displayed on the display unit 19 via the diagnostic data display means 21 in order to execute the secondary diagnosis in consideration of the relationship. The patrol officer performs the re-payment inspection according to the displayed re-payment inspection item and inputs the result. The screen shows, for example, FIG.
As shown in, the contents of the patrol inspection items that need to be investigated and the collection method are displayed. The entered answer is again sent to the inspection data file f by the inspection data input means 11.
Stored in 1.

When the input completion button is selected at the time when the input work is completed for all the re-survey inspection items, the diagnostic execution requesting means 13 returns the response data (re-survey inspection data).
Is transmitted to the equipment status diagnosis processing device 3 via the transmission line 5, similarly to the equipment diagnosis (primary diagnosis) based on the first inspection inspection data. The facility status diagnosis processing device 3 executes detailed diagnosis (secondary diagnosis) in consideration of the relationship between the devices based on the data of the re-survey inspection input by the patrol officer in the same procedure as the primary diagnosis. The secondary diagnosis result obtained by this is again transmitted to the portable patrol inspection data input processing device 1 via the transmission path 5, and is displayed on the display unit 19 by the diagnostic data display means 21.

FIG. 16 shows a screen display example of the secondary diagnosis result. In the screen division 91 in the figure, a causal relation diagram is displayed in which tree-structured events that may cause abnormalities in plant equipment are displayed, and abnormal events related to inspection inspection items that are determined to be abnormal in equipment diagnosis. Is displayed in different colors, and what seems to be the cause of the occurrence of the abnormal event is shown from the factors located below it in the causality diagram. The result of the secondary diagnosis is displayed in text on the screen section 93, similarly to the primary diagnosis result display screen. The coping method at the time of abnormality is also displayed in the text in the screen division 95.

In this way, the patrol staff can immediately judge the equipment status at the level of a skilled engineer and detect the equipment abnormality at an early stage by performing the equipment status diagnosis while on the spot, and can also monitor the plant. Skilled technicians operating the plant from a distance in the room can check the details of the diagnosis performed by the patrol staff including the diagnosis history without going to the site, and give advice to the patrol staff when necessary. It is also possible to grasp the detailed equipment status.

In the above-described embodiments, the site inspection work, which has conventionally been mostly entrusted to the knowledge of the patrol officer, is a plant constructed by the collected plant measurement data and the knowledge of the skilled engineer who is registered in advance. By performing the diagnosis according to the equipment diagnosis rule, it is possible to determine the plant equipment status which does not deviate from the individual level of the patrol officer. In the past, if the patrol officer did not know how to deal with the abnormality found at the site, he would ask the skilled engineer in the plant control room for instructions by telephone or the skilled engineer would actually Although there was no other than going to the site, the present invention allows a treatment method corresponding to the abnormality that has occurred to be immediately obtained at the site. In addition, by showing the details of the details to the supervisor in the plant control room, it is possible to check the details and give advice to the patrol officers at the site. It is possible to perform patrol inspection work of work.

In the above embodiment, the advice given to the patrol at the time of executing the facility diagnosis is manually input by the monitor after confirming the facility diagnosis on the display unit of the facility diagnostic apparatus. By similarly saving the diagnosis result at that time and the treatment method actually performed by it in the history data file that saves the inspection result, the past diagnosis saved in the history data file will be saved at the next diagnosis execution. It is also possible to retrieve the result data having similar diagnostic results and display the content and treatment method as guidance.
