  In an electric power company, telemetry data (data representing the measured values and operational status of equipment) transmitted from multiple monitored control stations such as distant substations and power stations is received and displayed by a centralized monitoring and control device. The operating status of the monitored control station is centrally monitored by a centralized monitoring control station established in the head office. FIG. 19 shows an example of the configuration, and power is supplied from a plurality of monitored control stations such as the A substation 11a, the B substation 11b, and the C power plant 11c and the centralized monitoring control device 20 in the centralized monitoring control station 12. Connection is made via the information network 13. The centralized monitoring control device 20 includes an information collection / distribution device 21, a remote monitoring control device 22, a control console 23, and a display unit 24. The information collection / distribution device 21 is connected to the power supply information network 13 to determine and relay information. The remote monitoring control device 22 receives telemeter data from the monitored control station supplied via the information collection and distribution device 21 and displays the telemeter data on the display unit 24, and remote control information based on a command from the control console 23. It is generated and sent to the information collection and distribution device 21. The information collection and distribution device 21 transmits remote control information to a predetermined monitored control station via the power supply information network 13. The control console 23 inputs commands for remote control and various controls. The display unit 24 displays telemeter data from the monitored control station received by the remote monitoring control device 22.

  In the above configuration example, the remote monitoring control device 22 receives telemeter data transmitted from a plurality of monitored control stations such as the A substation 11a via the power supply information network 13 and the information collection and distribution device 21. By displaying on the display unit 24, the centralized monitoring control station 12 can centrally monitor the operating states of a plurality of monitored control stations. If necessary, the remote control information is generated by the remote monitoring control device 22 by operating the control console 23, and the remote control information is transmitted to the predetermined monitored control via the information collection / distribution device 21 and the power supply information network 13. By transmitting to a place, it is possible to remotely control the operation state of a predetermined monitored control place.

  By the way, when the telemeter data from the monitored control station is received and displayed on the display unit 24 as described above, the telemeter data from other monitored control stations is not mixed, and the telemetry data from the predetermined monitored control station is not mixed. Needless to say, only the telemeter data must be correctly received and accurately displayed on the predetermined display unit 24. Therefore, the remote monitoring control device 22 (centralized monitoring control device 20) is tested to determine whether telemeter data from a predetermined monitored control station is correctly received and displayed on the predetermined display unit 24 correctly. In that case, a tester is assigned to a predetermined monitored control station to be tested, for example, the A substation 11a and the centralized monitoring control station 12, and the two testers communicate with each other by telephone or the like. When the telemeter data is transmitted, it is confirmed whether the telemeter data is correctly received by the remote monitoring control device 22 and displayed on the predetermined display unit 24 accurately.

  However, in the test method for the centralized monitoring and control apparatus as described above, telemeter data must be input one by one, and the scheduled recording function must input telemeter data at each fixed time, and further perform a test. Since it is necessary to place testers in both the predetermined monitored control station and the centralized monitoring control station 12, it takes a lot of time and manpower, and it is inefficient because it is necessary to keep in touch with the telephone. In addition, there is a drawback that there is a problem in accuracy because mistakes caused by communication also occur.

  The present invention has been made in view of the above points, and an object thereof is to provide a test method for a centralized monitoring control apparatus capable of efficiently and accurately testing the centralized monitoring control apparatus only in the centralized monitoring control station. To do.

  A test method for a centralized monitoring control apparatus according to the present invention is a test method for testing a centralized monitoring control apparatus that receives telemeter data transmitted from a plurality of monitored control stations and displays the telemeter data on a display unit. The centralized monitoring and control device is equipped with a tester that generates test data in place of the telemeter data from the location, and the centralized monitoring and control device is tested by receiving the test data generated from this tester and displaying it on the display unit. The tester simultaneously displays test data at all telemeter data display positions on the display unit by simultaneously generating a plurality of test data corresponding to all of the plurality of telemeter data from each monitored control station. It is characterized by.

  Further, the tester simultaneously generates test data instead of telemeter data for all or a part of the plurality of monitored control stations, and simultaneously displays the test data on each display unit, thereby allowing a plurality of monitored objects. All or part of the supervisory control station can be tested simultaneously. Further, the tester sequentially generates a plurality of types of test data. The test data is generated as numerical data, and is numerical data corresponding to the normal value of each monitored control station and numerical data corresponding to the ID of the telemeter data. Further, the test data further includes numerical data corresponding to the abnormal value of each monitored control station. When numerical data corresponding to an abnormal value is displayed on the display unit, the display unit displays an abnormal state. Further, in order to test the scheduled recording function, the tester can generate test data sequentially in accordance with each time when the centralized monitoring and control apparatus fetches data. The display state of the display part can be printed out as it is or stored and tested.

  According to the test method of the centralized monitoring control apparatus of the present invention as described above, a tester that generates test data instead of the telemeter data from each monitored control station is provided in the centralized monitoring control apparatus, and the tester Since the generated test data is received and the centralized monitoring control apparatus is tested, the centralized monitoring control apparatus can be efficiently and accurately tested only within the centralized monitoring control station. In addition, the tester simultaneously generates a plurality of test data corresponding to all of the plurality of telemeter data from each monitored control station, thereby simultaneously displaying the test data at all telemeter data display positions on the display unit. Since all the telemeter data display positions can be tested at the same time, the test data is displayed one by one at each telemeter data display position of the display unit, and compared with the method of testing one telemeter data display position one by one. Test efficiently.

  Next, an embodiment of a test method for a centralized monitoring control apparatus according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a configuration diagram for explaining an embodiment of the present invention. A central monitoring control device 20 in a central monitoring control station 12 is connected to a remote monitoring control device 22 and a tester 25 is added. Other configurations in FIG. 1 are the same as those in FIG. 19, and the same portions are denoted by the same reference numerals as those in FIG.

  The tester 25 generates test data in place of telemeter data transmitted from each monitored control station such as the A substation 11a and the B substation 11b. Therefore, in this embodiment, the remote monitoring control device 22 (centralized monitoring control device 20) tests, that is, telemeter data from a predetermined monitored control station is correctly received by the remote monitoring control device 22, and is correctly displayed on the predetermined display unit 24. When the test of whether to display is performed, telemeter data from the monitored control station is not received, but instead, the test data generated from the tester 25 is received by the remote monitoring control device 22 and displayed on the display unit 24. Is implemented.

  At this time, the tester 25 simultaneously generates a plurality of test data corresponding to all of the plurality of telemeter data from each monitored control station, for example, by time division multiplexing. Therefore, when the remote monitoring control device 22 receives the test data from the tester 25 and displays it on the display unit 24, the test data is displayed on the display unit 24 at all telemeter data display positions simultaneously. The reception display status of all telemeter data display positions can be tested simultaneously. FIG. 5 shows an example in which test data is simultaneously displayed at all telemeter data display positions of the display unit 24. The display unit 24 includes four telemeter data display positions on the left side and five right side positions. The test data is displayed at the same time as the telemeter data display position. In this way, if test data is simultaneously displayed at all telemeter data display positions and the reception display state of all telemeter data display positions can be simultaneously tested, one test data is displayed at each telemeter data display position of the display unit 24. It is possible to perform the test more efficiently as compared to the method of displaying and testing the telemeter data display position one by one.

  Further, the tester 25 simultaneously generates test data, for example, in parallel, instead of telemeter data, for all of the plurality of monitored control stations. Therefore, when the remote monitoring control device 22 receives the test data from the tester 25 and displays it on the display unit 24, the display unit 24 displays all the monitored units 24a as shown in FIG. , 24b, 24c simultaneously display test data of each monitored control station. In FIG. 2, 24a is a display unit for the A substation 11a, 24b is a display unit for the B substation 11b, 24c is a display unit for the C power plant 11c, and all these display units 24a, 24b, 24c. At the same time, the test data of each monitored control station is displayed. Therefore, in this embodiment, for all monitored control stations of the A substation 11a, the B substation 11b and the C substation 11c, the test display is received instead of the telemeter data and the reception display state is simultaneously tested. And more efficient testing is possible. At this time, in each display part 24a, 24b, 24c of FIG. 2, test data is simultaneously displayed on all the telemeter data display positions similarly to FIG. Note that, from the tester 25, it is possible to simultaneously generate test data for some, not all of the plurality of monitored control stations.

  FIG. 3 is a block diagram showing a specific configuration of the tester 25. The tester 25 includes a storage unit 31, a data generation unit 32, a data transmission unit 33, and a control unit 34. The storage unit 31 stores the test data. The data generation unit 32 acquires test data from the storage unit 31 and generates test data in the same form as the telemeter data. The data transmission unit 33 transmits the test data generated from the data generation unit 32 to the remote monitoring control device 22. The control unit 34 controls the storage unit 31, the data generation unit 32, and the data transmission unit 33.

  The test data generated from such a tester 25 is generated as numerical data, and has numerical data corresponding to the normal value of each monitored control station and numerical data corresponding to the ID of the telemeter data. Furthermore, as numerical data corresponding to the ID of the telemeter data, for example, numerical data corresponding to each monitored control station ID (each monitored control station number), corresponding to the transmission channel ID (channel number) of each monitored control station Numerical data corresponding to the telemeter individual item ID (word number) of each monitored control station, and numerical data corresponding to the type ID of each telemeter data (type of telemeter data such as current, voltage, water level, flow rate) Have. Further, the test data includes numerical data corresponding to abnormal values at each monitored control station. The tester 25 generates these test data automatically or sequentially based on the tester's operation from the control console 23.

  4 to 9 show one example of the display unit 24 when the test data is sequentially generated from the tester 25, received by the remote monitoring control device 22 and displayed on the display unit 24 for testing. Indicates the screen status. These screen states are when the monitored control station is the Hiroshima substation, and the test data for the Hiroshima substation is generated from the tester 25 and the test data is displayed on the display unit 24 for the Hiroshima substation. .

  FIG. 10 shows normal values of the Hiroshima substation (normal values are displayed at each telemeter data display position of the display unit 24). In the case of the Hiroshima Substation, there are four telemeter data display positions on the left side (input side) and five positions on the right side (output side) of the display unit 24. Each telemeter data display position has a normal value as shown in the figure. Numerical values, that is, 3000A, 110kV, 3000A, 110kV, 600A, 600A, 600A, 1200A, 600A are displayed. Accordingly, when the numerical data corresponding to the normal value is generated from the tester 25 and displayed on the display unit 24, the normal value information is correctly received if the same numerical value as described above is displayed at each telemeter data display position. It will be displayed.

  The monitored control station ID of the Hiroshima substation is “5”. Therefore, when the numerical data corresponding to the monitored control station ID is generated from the tester 25 and displayed on the display unit 24, if “5” is displayed at each telemeter data display position, the monitored control station ID of the monitored control station ID is displayed. The information is correctly received and displayed.

  FIG. 11 shows the transmission channel ID and telemeter individual item ID (a state in which these IDs are displayed at each telemeter data display position of the display unit 24) of the Hiroshima Substation. The transmission channel IDs of Hiroshima Substation are 1 to 3 displayed on the left side of “ch”. Therefore, when numerical data corresponding to the transmission channel ID is generated from the tester 25 and displayed on the display unit 24, if numerical values 1 to 3 are displayed at the respective telemeter data display positions as in FIG. The transmission channel ID information is correctly received and displayed. The telemeter individual item ID of the Hiroshima substation is 201, 202, 211, 212, 100, 101, 102, 10, 11 displayed on the left side of “w”. Therefore, when the numerical data corresponding to the telemeter individual item ID is generated from the tester 25 and displayed on the display unit 24, if the same numerical value as in FIG. 11 is displayed at each telemeter data display position, the telemeter individual item is displayed. The ID information is correctly received and displayed.

  Specific relations between voltage and current values and telemeter data ID are shown in Tables 1 and 2 below. When the normal value is FIG. 10, the telemeter data type ID is 105, 95, 105, 95, 101, 101, 101, 102, 101 from Table 1 and Table 2. Therefore, when numerical data corresponding to the type ID of the telemeter data is generated from the tester 25 and displayed on the display unit 24, if the same numerical value as described above is displayed at each telemeter data display position, the telemeter data The type ID information is correctly received and displayed.

  FIG. 4 shows a case in which numerical data corresponding to the normal value of the monitored control station is generated from the tester 25 and displayed on the display unit 24. In this case, each telemeter data display position is the same as FIG. A numerical value is displayed, and it can be seen that the normal value information was correctly received and displayed.

  FIG. 5 shows a case where the numerical data corresponding to the monitored control station ID is generated from the tester 25 and displayed on the display unit 24 next to FIG. In FIGS. 5 to 9, the units of “A” and “kV” can be ignored regardless of the test. Since the monitored substation ID of the Hiroshima substation is “5”, “5” should be displayed at all telemeter data display positions on the screen of FIG. However, in the screen of FIG. 5, “7” is displayed at the telemeter data display position in the lower left. This is because the operation of the remote monitoring control device 22 is not correct and data from other monitored control stations are mixed. This means that other data can be found immediately. In this case, the setting of the remote monitoring control device 22 is changed to adjust the correct display so that all values are “5”.

  FIG. 6 shows a case where numerical data corresponding to the transmission channel ID is generated from the tester 25 and displayed on the display unit 24 after FIG. 5. In this case, each telemeter data display position is displayed as “ The same numerical value as the numerical value on the left side of “ch” is displayed, and it can be seen that the transmission channel ID information is correctly received and displayed.

  FIG. 7 shows a case in which numerical data corresponding to the telemeter individual item ID is generated from the tester 25 and displayed on the display unit 24 next to FIG. 6. In this case, each telemeter data display position is shown in FIG. The same numerical value as that on the left side of “w” is displayed, and it can be seen that the information of the telemeter individual item ID is correctly received and displayed.

  FIG. 8 shows a case where numerical data corresponding to the type ID of each telemeter data is generated from the tester 25 and displayed on the display unit 24 after FIG. 7. In this case, the normal values shown in FIG. And the above-mentioned numerical value obtained from the relationship of Table 2 is displayed at each telemeter data display position, and it can be seen that the information of the type ID of each telemeter data is correctly received and displayed.

  FIG. 9 shows a case where numerical data “150” corresponding to an abnormal value is generated from the tester 25 and displayed on the display unit 24 after FIG. 8. Since the Hiroshima substation is a 110 kV system (this is stored in the remote monitoring control device 22), when “150” is displayed, the telemeter data display position “150” of the 110 kV voltage type is displayed. The display (“150” portion) is an abnormal value and blinks in an abnormal color (red). This is a test of whether an abnormality is displayed when an abnormal value is displayed. In this example, the display of “150” (“150” portion) at the telemeter data display position displaying the voltage type of 110 kv blinks in an abnormal color and displays an abnormality, so that the display is correct.

  The above is a case where a test is performed in real time while viewing the display unit 24. However, in the case of a test that takes time, a storage device and a printer for storing the display state of the display unit are prepared in the centralized monitoring control device 20. Then, after the test, the test result which is the display state of the display unit may be printed out so that the test result can be confirmed after the test. Further, even when the test is performed in real time while viewing the display unit 24, the display state of the display unit can be printed out as it is.

  According to one embodiment as described above, the centralized monitoring control device 20 is provided with the tester 25 that generates test data instead of the telemeter data from each monitored control station, and the test from the tester 25 is performed. Since the remote monitoring control device 22 (centralized monitoring control device 20) is tested by receiving the data, the centralized monitoring control device 20 can be efficiently and accurately tested only within the centralized monitoring control station 12. Can do. Moreover, the tester 25 simultaneously displays test data at all telemeter data display positions on the display unit 24 by simultaneously generating a plurality of test data corresponding to all of the plurality of telemeter data from each monitored control station. Since all the telemeter data display positions can be tested at the same time, the test data is displayed one by one at each telemeter data display position of the display unit, and the telemeter data display position is tested one by one. The test can be performed efficiently in comparison. Further, the tester 25 simultaneously generates test data instead of telemeter data for all or a part of the plurality of monitored control stations, and simultaneously displays the test data on each display unit. Since all or a part of the monitoring control station can be tested at the same time, the test can be performed more efficiently. In addition, when testing the scheduled recording function, a method of testing at regular intervals by using a function such as the nighttime to automatically generate a plurality of test data of the tester 25 and causing the test to be performed automatically. The test can be performed more efficiently than the above.

The above-mentioned scheduled recording function and its test will be described in detail below.
Telemeter data from power plants and substations is recorded at regular intervals for facility management and system operation, as well as real-time display for constantly monitoring power system abnormalities. Recording is a function of acquiring and processing data every hour or every 10 minutes. For example, an image of a recording screen in which instantaneous values of voltage and current are taken as they are every hour is as shown in FIG. FIG. 12 shows the case of the Hiroshima substation, in which data taken every hour is displayed (recorded) in each item of the Hiroshima substation 110 kV bus voltage, the Hiroshima substation 6.6 kV bus voltage, and the XX line current. The centralized monitoring and control apparatus has many such recording screens.

  In FIG. 12, although the recording timing is every hour, it varies depending on the purpose, such as every 5, 10, 30 minutes... 1, 6, 24 hours, and a method for efficiently testing these is required. In the past, data was input by a tester at every scheduled timing, or data was input by advancing the computer clock, but it took time to test with thousands of items.

  On the other hand, since the tester 25 can automatically generate a plurality of types of test data sequentially, the clocks of the tester 25 and the remote monitoring control device 22 are set together for remote monitoring. The test of the scheduled recording function can be automatically performed by automatically generating predetermined test data sequentially every time before the data recording and collection time by the control device 22. Moreover, the tester 25 automatically generates test data for all or some of the scheduled recording functions in the remote monitoring control device 22 in consideration of the recording collection time of each data, so that the remote monitoring control device 22 All or some of the scheduled recording functions can be tested simultaneously. Further, the tester 25 automatically generates test data at various cycles in consideration of the record collection time of each data, thereby efficiently and efficiently simultaneously performing a plurality of types of scheduled recording functions having different record capture cycles. Can be tested.

  13 to 18 show numerical data corresponding to each monitored control station ID, numerical data corresponding to transmission channel ID (channel number), numerical data corresponding to telemeter individual item ID (word number), and each telemeter data. The numerical data corresponding to the type ID (telemeter data type), the numerical data corresponding to the abnormal value, and the numerical data corresponding to the normal value are automatically generated from the tester 25 in this order every hour, and the Hiroshima Electric Transformer The state of the recording screen of the display unit 24 when a test is performed with respect to the regular recording function of the place is shown.

At 2 o'clock, the data is taken into the remote monitoring control device 22, and the data is displayed in all items of the recording screen as shown in FIG. In FIG. 14, the Hiroshima substation 110 kV bus voltage is displayed as 1 channel, the Hiroshima substation 6.6 kV bus voltage and the XX line current are displayed as 2 channels, and the correct channel data is displayed. Therefore, it can be seen that the correct channel data of the Hiroshima Substation has been captured so far.

  Next, at 2:50, the tester 25 automatically transmits “numerical data corresponding to the telemeter individual item ID (word number)”. At 3 o'clock, the data is taken into the remote monitoring control device 22, and the data is displayed in all items of the recording screen as shown in FIG. In FIG. 15, the Hiroshima substation 110 kV bus voltage is displayed as 30 words, the Hiroshima substation 6.6 kV bus voltage is displayed as 35 words, and the XX line current is displayed as 36 words, and correct word data is displayed. Therefore, it can be seen that the correct word data of the correct channel of the Hiroshima Substation has been captured so far.

  Next, at 3:50, the tester 25 automatically transmits “numerical data corresponding to the type ID (type of telemeter data) of each telemeter data”. At 4 o'clock, the data is taken into the remote monitoring control device 22, and the data is displayed in all items of the recording screen as shown in FIG. In FIG. 16, the Hiroshima substation 110 kV bus voltage is displayed as 95 types, the Hiroshima substation 6.6 kV bus voltage as 90 types, and the XX line current as 101 types, and correct type data is displayed. Thus, it can be seen that the correct telemeter data type of the correct word of the correct channel of the Hiroshima substation has been captured so far.

  Next, at 4:50, the tester 25 automatically transmits “numerical data corresponding to an abnormal value”. At 5 o'clock, the data is taken into the remote monitoring control device 22, and the data is displayed on all items of the recording screen as shown in FIG. In FIG. 17, the Hiroshima substation 110 kV bus voltage is 150 kV (displayed in red (abnormal color)), the Hiroshima substation 6.6 kV bus voltage is 9.0 kV (displayed in red (abnormal color)), and the ○○ line current is 720 A (red) (Abnormal color) display), and in both cases, abnormal values are displayed in abnormal color display. Therefore, it can be seen that data of the correct telemeter data type of the correct word of the correct channel of the Hiroshima substation has been fetched and correctly displayed in an abnormal color with the corresponding abnormal value.

  Next, at 5:50, the tester 25 automatically transmits “numerical data corresponding to a normal value”. At 6 o'clock, the data is taken into the remote monitoring control device 22, and the data is displayed on all items of the recording screen as shown in FIG. In FIG. 18, the Hiroshima substation 110 kV bus voltage is 110 kV (normal color display), the Hiroshima substation 6.6 kV bus voltage is 6.6 kV (normal color display), and the XX line current is 600 A (normal color display). In both cases, the correct value is displayed in normal color. Therefore, after the data of the correct telemeter data type of the correct word of the correct channel of the Hiroshima Substation is captured and displayed with the correct abnormal color with the corresponding abnormal value, the normal value of each telemeter data is entered and all the normal colors It turns out that everything is normal.

  As described above, it is possible to test the scheduled recording function of the Hiroshima Substation. Further, in the same manner, the test data is automatically generated by the tester 25 in consideration of the record collection time of each data, so that the scheduled monitoring record for all or part of the monitored control stations in the remote monitoring control device 22 is performed. Can be tested for functionality simultaneously.
