The input / output I / F 14b is connected to a keyboard 16 as a user interface, a mouse 17, and a display 18.

  The CPU 11 controls the overall operation of the information providing apparatus 10. The RAM 12 functions as a working area for the CPU 11. The ROM 13 stores a control program and data for controlling the operation of the CPU 11. The CPU 11 reads out the control program stored in the ROM 13 as necessary, transfers it to the RAM 12 and develops it. And CPU11 controls each part of the information provision apparatus 10 by reading and executing the control program expand | deployed by RAM12.

  The network I / F 14 a is an interface for transmitting and receiving data via the network 40. The input / output I / F 14b defines a data exchange control method and the like. Input information operated by the keyboard 16 and the mouse 17 is processed by the CPU 11 via the input / output I / F 14b. Display information controlled by the CPU 11 is also displayed on the display 18 via the input / output I / F 14b. The display 18 includes a display device such as an LCD (Liquid Crystal Display). In addition, the HDD 15 stores address information of all power plants and substations.

  The data collection device 20 includes a CPU 21, a RAM 22, a ROM 23, a network I / F 24, an HDD 25, and a bus 26. The CPU 21 of the data collection device 20 captures operation data indicating the operation status of the installed power plant or substation. The HDD 25 temporarily stores the operation data thus taken. Since the configuration and operation of each other part are the same as the corresponding parts of the information providing apparatus 10 described above, a detailed description thereof will be omitted.

  The server 30 includes a CPU 31, RAM 32, ROM 33, network I / F 34, HDD 35, and bus 36. In the HDD 35, operation data collected in the past is stored so as to be readable based on the identification information. Since the configuration and operation of the other units are the same as the corresponding units of the information providing apparatus 10 described above, the details thereof will be omitted.

  Hereinafter, the operation performed in the information providing system 100 when operation data is received from the power plant and the substation will be briefly described.

  As shown in FIG. 1, the data collection device 20 is installed in each of a plurality of power plants and substations, and takes in operation data indicating the operation status of these power plants and substations. At this time, the CPU 21 constitutes a capturing unit. The operation data refers to, for example, current information, voltage information, device operation, contact information on device failure, and the like. The operation data varies depending on the equipment and facilities of the power plant and substation.

  Thereafter, the CPU 21 generates the identification information for specifying the type of operation data taken in and the power plant or substation where the data collection device 20 is installed. Here, the type of operation data varies depending on the operation data, and is used as a judgment material for determining whether the operation data is defective (current information, voltage information, contact information, etc.), or an object for which the operation data is taken in (Equipment such as a circuit breaker and a protection device) and a place (a power transmission line, a transformer, a distribution line, etc.) where such an object is installed.

  The identification information is added to the operation data and transmitted to the server 30 via the network I / F 24 and the network 40. At this time, the CPU 21 constitutes a data transmission unit.

  The CPU 31 of the server 30 takes in the operation data sent from the data collection device 20 by the network I / F 34 and, based on the identification information added via the bus 36, converts the operation data into each type of operation data. In addition, the data is stored in the HDD 35 as a storage unit so as to be readable in time series for each power plant and based on the sent time. As described above, since the server 30 sequentially stores the operation data, the information providing apparatus 10 does not need to sequentially store the operation data that is sent, and the processing capability of the information providing apparatus 10 is not burdened.

  The CPU 31 of the server 30 reads the operation data stored in the HDD 35, adds the identification information, and receives information via the network I / F 34 and the network 40 when there is a request to read the operation data from the information providing apparatus 10. To the providing device 10. At this time, the CPU 31 constitutes a transmission unit.

  The CPU 11 of the information providing apparatus 10 sequentially transmits a read request to the server 30 and receives the operation data and the identification information transmitted from the server 30 via the network 40 by the network I / F 14a, and converts them into the operation data. Determine if there is a defect. At this time, the CPU 11 constitutes a determination unit.

  When the CPU 11 determines that any of these operation data is defective, the CPU 11 displays the type of operation data and the name of the power plant or substation on the display 18 based on the added identification information. At this time, the display 18 constitutes a display unit, and the CPU 11 constitutes a display control unit.

  Further, the CPU 11 distributes the information related to the operation data, for example, the type of the operation data, and the power plant name or the substation name to the related places shown in FIG. 1 by using e-mail, for example. The address of the relevant part is registered in the HDD 15 in advance, for example. At this time, the CPU 11 constitutes an information distribution unit.

  Hereinafter, as an example in which the information providing system 100 is specifically used, a case where the operation data transmitted from the data collection device 20 installed in the A power plant is current information and voltage information of the device a will be described. .

  The CPU 21 of the data collection device 20 of the A power plant shown in FIG. 1 sequentially takes in the current information indicating the current value of the device a and the voltage information indicating the voltage value, which are operation data indicating the operation status, from the device a. In this case, the operation data is a current value flowing through the device a and a voltage value applied to the device a.

  The CPU 21 generates identification information for specifying the type of operation data and the A power plant. In this case, since the operation data is the current value and voltage value of the device a, the type of operation data is that the current value and voltage value are materials for determination, the device a that is the measurement target, Further, it refers to a place P where the device a is installed. The CPU 21 adds the generated identification information to the operation data and transmits it to the server 30 via the network 40.

  Since the operation of the CPU 31 of the server 30 is as described above, the description thereof is omitted.

  FIG. 3 is a flowchart showing the operation of the CPU 11 of the information providing apparatus 10 when the current information and voltage information of the device a included in the A power plant is received. Hereinafter, the operation of the CPU 11 will be described with reference to FIG.

  The CPU 11 starts operation at step ST1 and transmits a read request to the server 30. In step ST2, the CPU 11 receives, via the network I / F 14a, current information and voltage information to which identification information is added, which is sent from the server 30 that has received the read request via the network 40.

  Next, CPU11 reads the setting data of apparatus a by step ST3 based on the identification information received by step ST2. The setting data indicates a range of current values and voltage values when the device is operating normally. The setting data is stored in advance in the HDD 15, for example.

  In step ST4, the CPU 11 compares the current information and voltage information of the device a with the setting data of the device a read in step ST3, and the current value and voltage value of the device a sent are indicated by the setting data. It is determined in step ST5 whether or not the range is deviated.

  If it is determined in step ST5 that the current value and voltage value indicated by the received current information and voltage information are within the range indicated by the setting data, the CPU 11 ends the series of operations in step ST8.

  Conversely, if the CPU 11 determines in step ST5 that the current value and voltage value indicated by the sent current information and voltage information deviate from the range indicated by the setting data, the identification information is determined in step ST6. The display information including the device a, the current value and the voltage value indicated by the device a, the power plant A, and the place P where the device a is installed is displayed on the display 18. Further, the time when the current information and the voltage information are received may be displayed together.

  Next, in step ST7, the CPU 11 distributes information including the device a, the current value and the voltage value of the device a, the power plant A, and the location P to the related locations shown in FIG. 1 using email. This information may be distributed by other methods such as facsimile communication instead of e-mail. Then, CPU11 complete | finishes a series of operation | movement by step ST8.

  In this way, the information providing device 10 collates the current information and voltage information sent from the data collection device 20 with the setting data, and these current information and voltage information deviate from the range indicated by the setting data. 1 is distributed, the information including the location where the related location shown in FIG. 1 is defective is distributed, so that it is possible to notify the related location of the failure reliably and without delay.

  Next, the case where the operation data sent by the data collection device 20 is contact information such as the operation of the device b will be described.

  For example, when the CPU 21 of the data collection device 20 detects any change in the contact information of the device b, it adds identification information to the contact information and transmits it to the information providing device 10 and the server 30 via the network 40. In this case, the identification information includes that the device is b, that the device b is at the A power plant, and that the operation data is contact information.

  Since the operation of the server 30 is as described above, the description thereof is omitted.

  FIG. 4 is a flowchart illustrating the operation of the CPU 11 of the information providing apparatus 10 when the contact information of the device b is received from the server 30. Hereinafter, the operation of the CPU 11 will be described with reference to the flowchart of FIG.

  First, in step ST11, the CPU 11 starts operation and transmits a read request to the server 30. In step ST12, the CPU 11 receives contact information and identification information transmitted from the server 30 that has received the read request. Next, in step ST13, the CPU 11 determines whether the contact information is caused by a failure due to the operation of the device b or a failure of a component constituting the device b, and the contact information is defective. Determine whether or not.

  If the CPU 11 determines in step ST13 that the contact information is not defective, the series of operations is terminated in step ST16.

  Conversely, if the CPU 11 determines that the contact information is defective in step ST13, the display information including the device b, the contact information of the device b, and the display information including the A power plant is displayed based on the identification information in step ST14. 18 is displayed. Further, the time when the contact information is received may also be displayed.

  Next, in step ST15, the CPU 11 transmits the information including the device b, the contact information of the device b, and the information about the A power plant to the related parts using an e-mail. Then, CPU11 complete | finishes a series of operation | movement by step ST16.

  As described above, the information providing apparatus 10 determines whether or not there is a defect in the contact information sent from the data collection apparatus 20, and if it is determined that there is a defect, there is a defect in the related portion shown in FIG. Since the information including the location is distributed, it is possible to reliably notify the relevant location that there is a problem without delay.

  Further, in any case described with reference to FIGS. 3 and 4, the relevant part shown in FIG. 1, for example, the equipment manufacturer, reads which mail is sent to which equipment at which place in which power station. In addition, since it is possible to know in advance what kind of trouble has occurred, maintenance and the like can be performed quickly.

  Furthermore, the information providing system 100 can be used to identify the accident point. For example, if you do not know where the accident occurred on the transmission line, the operation that shows the operation status of each system protection device installed at the power plant and substation to protect the transmission line from short circuit or ground fault Accident points can be identified based on the data.

  FIG. 5 is a diagram showing a conventional method for identifying an accident point. As shown in FIG. 5, there are a Q substation, an R substation, and an S substation, and an accident point locating device T for identifying an accident point is attached to the Q substation. In this case, the location where the accident point locating device T can determine the accident is only the range written as the possible location range shown in FIG.

  Therefore, for example, when an accident occurs at the accident point U that is within the range where no localization is possible, it is very difficult for the accident point locating apparatus T to specify the accident point. Thus, even if the accident point locating device T is purposely provided only for specifying the accident point, the accident point cannot often be specified depending on the accident point.

  FIG. 6 is a diagram illustrating an accident point identification method using the information providing system 100. Each of the Q substation, the R substation, and the S substation has a data collecting device 20, and these data collecting devices 20 are connected to the information providing device 10 and the server 30 via a network 40.

  For example, when an accident occurs on a transmission line managed by a Q substation, an R substation, and an S substation, the CPU 21 of the data collection device 20 installed in the Q substation, the R substation, and the S substation Accident occurrence information including the operation contact information, circuit breaker on / off information, and voltage / current increase / decrease amounts and phase changes of these devices is captured. The CPU 21 adds identification information to these pieces of information and transmits them to the server 30.

  The operation of the server 30 is the same as the operation described with reference to FIGS.

  FIG. 7 is a flowchart illustrating an operation in which the CPU 11 of the information providing apparatus 10 specifies an accident point. Hereinafter, the operation of the CPU 11 identifying the accident point will be described with reference to FIG.

  First, the CPU 11 starts in step ST21 and transmits a read request to the server 30. CPU11 receives accident occurrence information from server 30 at Step ST22. Next, in step ST23, based on the accident occurrence information, a voltage drop at each substation, a current shunt ratio, and an impedance calculation up to the accident point are performed. The information providing apparatus 10 stores in advance the power supply capacity behind each substation, the line constant of the transmission line, and the transmission line route diagram, and the above-described calculation is performed based on these.

  In step ST24, the CPU 11 calculates the distance from each substation to the accident point based on the plurality of values obtained as a result of the calculation in step ST23, and displays the distance on the display 18 in step ST25. Then, a series of operation | movement is complete | finished by step ST26.

  In this way, using the information providing device 10, it is possible to easily grasp the accident point based on the operation data sent from each data collection device 20 installed in each substation. Moreover, since the data collection device 20 is installed in each substation, the orientation accuracy does not deteriorate due to the accident point.

  Moreover, when specifying the accident point using the information providing system 100, the operation contact information of the system protection device, the on / off information of the circuit breaker, the voltage value / current value stored in the data collection device 20 are stored. It is also possible to verify whether the circuit breaker and the system protection device have normally operated by the information providing apparatus 10 using the accident occurrence information including the amount of increase / decrease and the phase change, and to perform analysis at the time of device operation.

  In this case, the information providing apparatus 10 stores in advance the power supply capacity behind each substation, the transmission line constant, the relay set value, and the sequence of each device at each substation. In addition, the power supply capacity behind each substation and the line constant of the transmission line are the same as those used when specifying the accident point as described above.

  The information providing apparatus 10 can perform analysis in the following procedure using the information described above.

  (1) The operating value of the system protection device is calculated from the increase / decrease amount of the current value / voltage value and the phase change.

  (2) The operation contact information and the relay settling value which have received the operation value of the system protection device are collated, and the system protection device operation sequence check and the operation quality determination are performed.

  (3) The circuit breaker operation is determined from the on / off information of the circuit breaker and the increase / decrease amount of the voltage value / current value.

  Based on these analysis results, the above-described analysis results (2) and (3) are displayed on the display 18 for each corresponding power plant or each substation.

  Furthermore, based on this information, an accident bulletin including information such as the distance to the accident point, substation name, circuit breaker name, analysis time, etc. is created, and the CPU 11 uses FIG. You may make it transmit to the related location shown.

  In this way, the accident occurrence information is transmitted to the information providing device 10 using the data collection device 20 installed at each substation, and the information providing device 10 identifies the point of the accident and analyzes the operation of each device. By delivering accident bulletins to the relevant locations, it is possible to notify the relevant locations of the occurrence of the accident without delay, and at a lower cost than installing the accident location system T just to identify the accident location. Can be suppressed.

  In the above-described embodiment, the data collection device 20 transmits the operation data to the server 30, and the server 30 that receives the read request from the information providing device 10 transmits the operation data to the information providing device 10. However, the information may be transmitted directly to the information providing apparatus 10 without going through the server 30.

  Further, the information providing apparatus 10 may not be connected to the network 40. In this case, when the information providing apparatus 10 transmits a read request to the server 30 and receives the operation data, the information providing apparatus 10 performs distribution to a related portion using another communication path (for example, a facsimile).

  The present invention provides information for distributing information related to operation data to a predetermined location when it is determined that any of the plurality of operation data indicating the operation status of the plurality of power plants and substations is defective. It is related to the system and can be applied when managing the operating status of power plants and substations.
