A power outage information providing device, a power outage information providing system, and a program according to embodiments will be described in detail below with reference to the drawings.

Embodiment 1.
FIG. 1 is a diagram illustrating a configuration example of a power outage information providing system according to a first embodiment; A power outage information providing system 1 of the present embodiment includes a display terminal 2 , a power outage information providing device 3 , a data storage device 4 and a measurement data management device 5 . The power outage information providing system 1 may include an equipment data management device 6 .

The measurement data management device 5 includes a data transmission section 51 , a missing measurement processing section 52 , a data acquisition section 53 and a data storage section 54 .

The data acquisition unit 53 acquires measurement data (hereinafter referred to as SM measurement data) of a smart meter (not shown), which is a metering device that periodically measures the power consumption of a consumer for automatic meter reading of power consumption. SM measurement data is stored in the data storage unit 54 . The data acquisition unit 53 may acquire SM measurement data from the smart meter via another device. A smart meter periodically transmits SM measurement data. The transmission cycle of SM measurement data is, for example, 30 minutes, but is not limited to this. SM measurement data, which is measurement data of a smart meter, includes SMID (Smart Meter Identifier), which is identification information of the smart meter, and time information indicating the time when the SM measurement data was transmitted. The data acquisition unit 53 also acquires high voltage measurement data, which is measurement data such as the voltage and current of the high voltage distribution line, and stores the high voltage measurement data in the data storage unit 54 . It is assumed that high pressure measurement data is also periodically transmitted from a measuring device (not shown). The high pressure measurement data includes identification information of the measurement value and time information indicating the time when the high pressure measurement data was transmitted.

The missing data processing unit 52 determines the power outage state of the smart meter, that is, the power outage state of the customer corresponding to the smart meter, based on the communication state of the smart meter. For example, if the latest SM measurement data stored in the data storage unit 54 for each smart meter cannot be acquired even after a certain period of time has passed since the previous transmission time, the missing measurement processing unit 52 sends the data to the smart meter. It is determined that communication failure has occurred, and that the smart meter is in a power outage state. The missing measurement processing unit 52 generates SM measurement data in which information indicating that the measurement was missing due to communication failure is stored in the measurement value portion of the smart meter determined to have a communication failure. SM measurement data is stored in the data storage unit 54 . Alternatively, the missing measurement processing unit 52 stores communication failure information indicating that communication failure has occurred in the data storage unit 54 together with the SMID separately from the SM measurement data for the smart meter determined to have communication failure. You may

Similarly to the SM measurement data, the missing measurement processing unit 52 determines that a communication failure has occurred in the measuring device when the high pressure measurement data cannot be acquired even after a certain period of time has passed since the previous transmission time. and determines that the measuring device is in a power outage state. The missing measurement processing unit 52 generates high pressure measurement data in which information indicating that the measurement was missing due to communication failure is stored in the measurement value portion of the measurement device determined to have a communication failure. The high pressure measurement data is stored in the data storage unit 54 . Alternatively, the missing measurement processing unit 52 stores communication failure information indicating that communication failure has occurred in addition to the high pressure measurement data, together with the identification information of the measurement device, for the measurement device determined to have communication failure. It may be stored in section 54 . Also, here, an example of determining the power failure state of the high voltage distribution line based on the communication state of the high voltage measurement data will be described, but the power failure state of the high voltage distribution line is not limited to the example calculated from the communication state. Information acquired from another power distribution automation system or the like may be used.

When new data regarding at least one of the SM measurement data and the high pressure measurement data is stored in the data storage unit 54 , the data transmission unit 51 transmits the new data to the data storage device 4 .

The equipment data management device 6 manages equipment data, which is information about various equipment in the distribution system. The facility data includes information indicating the installation position and information indicating the connection relationship for each facility. Equipment in a distribution system includes, for example, various distribution lines such as high-voltage distribution lines, low-voltage distribution lines, and lead-in lines, transformers such as pole transformers, and smart meters. The facility data management device 6 transmits the updated facility data to the data storage device 4 .

The data storage device 4 includes a data transmission section 41 , a data acquisition section 42 and a data storage section 43 . The data acquisition unit 42 receives data from another device and stores the received data in the data storage unit 43 . For example, when the data acquisition unit 42 receives SM measurement data and high pressure measurement data from the measurement data management device 5 , the data acquisition unit 42 stores the received SM measurement data and high pressure measurement data in the data storage unit 43 . Further, when the data acquisition unit 42 receives the equipment data from the equipment data management device 6 , the data acquisition unit 42 stores the received equipment data in the data storage unit 43 . The data acquisition unit 42 also acquires map data from a map data providing device (not shown) and stores the acquired map data in the data storage unit 43 .

The data storage unit 43 stores map data, high pressure measurement data, SM measurement data, and facility data. The data storage unit 43 is, for example, a database that stores various data, and may be a data lake.

The data transmission unit 41 reads the data stored in the data storage unit 43 based on the data acquisition request received from the power outage information providing device 3 and transmits the read data to the power outage information providing device 3 . The data acquisition request includes type information indicating the type of data to be obtained, and display range information indicating the display range described later. For example, when a value indicating SM measurement data is specified as the type information in the data acquisition request, the data transmission unit 41 selects the SM measurement data specified by the display range information among the SM measurement data stored in the data storage unit 43. The data in the range of the power outage is extracted, and the extracted data is transmitted to the power outage information providing device 3 . Note that the data storage unit 43 may store the map data, the high pressure measurement data, the SM measurement data, and the facility data in association with information indicating the range on the map. , the data corresponding to the range specified by the data acquisition request may be extracted using the information indicating the position included in each data. The information indicating the range may be indicated by an address (place name) such as A town, K city, P prefecture, or may be indicated by latitude and longitude.

The power outage information providing device 3 includes a transmission/reception unit 31 , a data acquisition unit 32 and a display data generation unit 33 . The transmitter/receiver 31 communicates with the display terminal 2 . For example, the transmission/reception unit 31 receives display designation information designating display content from the display terminal 2 and outputs the received display designation information to the display data generation unit 33 . Further, the transmitting/receiving section 31 transmits the display data received from the display data generating section 33 to the display terminal 2 . The transmission/reception unit 31 is an example of an output unit that outputs display data. The output unit included in the power outage information providing device 3 may be a display unit that performs display. In this case, the output unit outputs display data by displaying the display data.

The display data generation unit 33 determines a range on the map to be displayed based on the display designation information received from the transmission/reception unit 31, generates a data acquisition request for acquiring various data corresponding to the determined range, Output to the data acquisition unit 32 . The display data generation unit 33 generates display data using various data received from the data acquisition unit 32 and outputs the generated display data to the transmission/reception unit 31 . In the present embodiment, the display data generation unit 33 generates display data for superimposing and displaying information indicating the power failure state determined from the communication state of the smart meter and information about the cause of the power failure. That is, the display data generator 33 generates display data for displaying information about the cause of the power failure together with power failure information indicating the power failure state in the smart meter estimated based on the communication status of the smart meter. As a result, in the present embodiment, it is possible to identify the location of the power failure in the low-voltage system and to assist in identifying the cause of the power failure. The information about the cause of the power failure is, for example, at least one of the location of the low-voltage distribution line, the location of the high-voltage distribution line, and power failure information of the high-voltage distribution line, as will be described later.

The data acquisition unit 32 acquires information about the cause of the power failure. Specifically, the data acquisition unit 32 transmits the data acquisition request received from the display data generation unit 33 to the data storage device 4 and outputs the data received from the data storage device 4 to the display data generation unit 33 .

The display terminal 2 is, for example, a terminal that can be viewed by a user such as an administrator who manages a power outage and a worker who performs recovery work from a power outage. The display terminal 2 includes an input reception section 21 , a transmission/reception section 22 and a display section 23 .

The input reception unit 21 receives input from the user and outputs information indicating the content of the received input to the transmission/reception unit 22 . For example, the input reception unit 21 receives information indicating display contents from the user, and outputs the received information to the transmission/reception unit 22 as display designation information.

The transmission/reception unit 22 communicates with the power outage information providing device 3 . For example, the transmission/reception unit 22 transmits the display designation information received from the input reception unit 21 to the power outage information providing device 3 . Further, for example, upon receiving display data from the power outage information providing device 3 , the transmission/reception unit 22 outputs the received display data to the display unit 23 . The display unit 23 displays the display data received from the transmission/reception unit 22 . In the present embodiment, as described above, the display data for superimposing and displaying the information indicating the power failure state determined from the communication state of the smart meter and the information about the cause of the power failure is generated. The unit 23 can superimpose and display information indicating the power failure state determined from the communication status of the smart meter and information about the cause of the power failure.

For example, the power outage information providing device 3 may have a function as a Web server, the display terminal 2 accesses a website and transmits display designation information, and the power outage information providing device 3 responds to the display designation information. The display data may be provided on a website. In addition, although one display terminal 2 is illustrated in FIG. 1, a plurality of display terminals 2 may be provided. The display terminal 2 may be a portable terminal such as a smart phone or a tablet, or may be a personal computer.

Further, in the example shown in FIG. 1, the display terminal 2 and the power outage information providing device 3 are separately provided, but the display terminal 2 and the power outage information providing device 3 may be integrated. For example, the power outage information providing device 3 may include a display unit, and the display unit may display the display data generated by the display data generation unit 33 .

Further, in the example shown in FIG. 1, the power failure information providing device 3 and the data storage device 4 are provided separately, but the power failure information providing device 3 also has a function as the data storage device 4. may be Further, the power outage information providing device 3 may have a function as the data storage device 4 and may also have a display unit as described above. That is, the display terminal 2, the power outage information providing device 3, and the data storage device 4 may be realized by one device.

Further, in the example shown in FIG. 1, the measurement data management device 5 determines the power failure of the smart meter, but the power failure information providing device 3 is not limited to this, the SM measurement data stored in the data storage device 4 may be used to determine a communication failure to determine a power failure. Similarly, the power outage information providing device 3 may determine communication failure using the high voltage measurement data stored in the data storage device 4 to determine power outage of the measuring device in the high voltage distribution line.

Next, the operation of this embodiment will be described. FIG. 2 is a flow chart showing an example of a processing procedure in the power outage information providing device 3 of the present embodiment. The power outage information providing system 1 of the present embodiment includes, for example, a first display enlarged to the extent that the position of each smart meter can be seen, a second display displaying the number of power outages in a specified area, and a smart meter It is possible to perform three types of display, including a third display that displays a list of power outage states for each unit. FIG. 2 shows an example in which display data corresponding to the first display is generated. Also, here, an example in which the three types of display described above are possible will be described, but the present invention is not limited to this, and only one of the three types described above may be displayed. Two of them may be displayable.

As shown in FIG. 2, the power outage information providing device 3 acquires display designation information (step S1). Specifically, the transmission/reception unit 31 receives the display designation information from the display terminal 2 to acquire the display designation information, and outputs the acquired display designation information to the display data generation unit 33 . The display designation information includes, for example, display range information indicating the range to be displayed. The user inputs to the display terminal 2 display range information indicating the range desired to be displayed. The display range information may be input as an address, or as latitude and longitude. good too.

The power outage information providing device 3 acquires facility data, map data, SM measurement data, and high pressure measurement data of the area corresponding to the display designation information (step S2). Specifically, the display data generation unit 33 generates a data acquisition request for requesting acquisition of facility data, map data, SM measurement data, and high pressure measurement data corresponding to the area indicated by the display range information in the display designation information. The data is output to the acquisition unit 32 , and the data acquisition unit 32 transmits a data acquisition request to the data storage device 4 . The data acquisition unit 32 receives data corresponding to the data acquisition request from the data storage device 4 and outputs the data to the display data generation unit 33 . At this time, the data storage device 4 transmits the latest data among the facility data, the map data, the SM measurement data and the high voltage measurement data to the power failure information providing device 3 respectively. It should be noted that when the blackout section of the high voltage distribution line is not determined based on the high voltage measurement data to be described later, the high voltage measurement data may not be acquired in step S2.

Next, the power outage information providing device 3 uses the acquired SM measurement data to determine a consumer who is estimated to have a power outage (step S3). Specifically, the display data generation unit 33 refers to the latest SM measurement data acquired from the data storage device 4 to determine whether or not information indicating that each smart meter has a communication failure is stored in the SM measurement data. By determining whether or not, it is determined whether or not there is a power failure. Then, the display data generation unit 33 determines the smart meter that is estimated to be out of power, that is, the consumer that is estimated to be out of power, using the determination result of whether each smart meter is out of power. . Further, as described above, when the communication failure information is generated separately from the SM measurement data, the communication failure information is acquired instead of the SM measurement data in step S2, and the display data generation unit 33 uses the communication failure information to determine the consumer who is presumed to have a power outage. In addition, the display data generating unit 33 may further determine the blackout section of the high-voltage distribution line based on the high-voltage measurement data.

Next, the power outage information providing device 3 generates display data based on the determination result, the acquired map data, the facility data and the high pressure measurement data (step S4). Specifically, the display data generation unit 33 displays the power outage determined from the communication state of the smart meter on the map based on the determination result of step S3 and the map data, facility data, and high pressure measurement data acquired in step S2. It generates display data for superimposing and displaying the information indicating the state and the information regarding the cause of the power failure, and outputs the generated display data to the transmission/reception unit 31 .

FIG. 3 is a diagram showing an example of information included in equipment data according to the present embodiment. FIG. 3 shows an example of equipment information of a smart meter. As shown in FIG. 3, the equipment data of the smart meter includes the SMID, the address of the customer where the smart meter is installed, the latitude where the smart meter is installed, the longitude where the smart meter is installed, and the smart meter. and a connecting distribution line indicating the distribution line to be connected. In the example shown in FIG. 3, both the address and the latitude/longitude are included in the facility data as information indicating the location of the facility. may Regarding other facilities such as high-voltage distribution lines, low-voltage distribution lines, and transformers, the facility data similarly includes identification information, position information, and connection distribution lines. The display data generator 33 can determine the position of each facility on the map based on the information indicating the position of each facility in the facility data.

Returning to the description of FIG. Next, the power outage information providing device 3 transmits the display data (step S5). Specifically, the transmission/reception unit 31 transmits display data to the display terminal 2 . The display terminal 2 displays the display data as described above.

FIG. 4 is a diagram showing an example of a display screen displayed on the display terminal 2 of this embodiment. FIG. 4 shows an example in which display is performed by the first display. In the example shown in FIG. 4, a high-voltage distribution line 61, a low-voltage distribution line 62, a smart meter 63 that is a power outage smart meter, a normal smart meter 64 that is not power outage, and a pole transformer are shown on the map. 65-1 to 65-4 are shown respectively. It should be noted that black-filled rhombus figures, even those without symbols, indicate smart meters during power outage, like the smart meter 63, and non-hatched rhombus figures without symbols. Similar to the smart meter 64, a normal smart meter is shown. Similarly, the linear figures with the same thickness as the high-voltage distribution line 61 are also high-voltage distribution lines, and the linear figures with the same thickness as the low-voltage distribution line 62 are indicated with codes. The part that is not covered is also a low-voltage distribution line. Although the service line is not shown in FIG. 4, a service line is drawn from the nearest low-voltage distribution line 62 to each customer.

In the first display exemplified in FIG. 4, the power failure information is displayed on the map by a graphic associated with the power failure state of each smart meter, and the equipment in the distribution system is displayed as cause estimation support information that is information on the cause of the power failure. is displayed on the map by a figure indicating each facility.

In this embodiment, by displaying the power failure status of each smart meter, the power failure status of each customer in the low-voltage system is displayed, and the location of high-voltage distribution lines, low-voltage distribution lines, etc. is displayed as cause estimation support information. are superimposed and displayed. As a result, the user can grasp the relationship between the smart meter, the high-voltage distribution line, and the low-voltage distribution line that are out of power. Further, FIG. 4 shows an example in which the power outage state of the high-voltage distribution line is also determined. The blackened portion of the high-voltage distribution line 61 is in the power outage state, and the hatched portion is in the normal state. be.

For example, both of the two smart meters shown above and to the right of the pole transformer 65-1 are out of power, but the section of the high-voltage distribution line 61 corresponding to them is out of power. The blackout state of the high-voltage distribution line is displayed in section units as illustrated in FIG. 4 . Therefore, there is a high possibility that the power outage of these two smart meters is caused by some kind of failure in the high-voltage distribution line 61 . On the other hand, the smart meter shown below and to the right of the pole transformer 65-1 is also out of power, but the other smart meter connected to the low-voltage distribution line in the same section is not out of power, The cause of the power outage may be damage to the service line. In addition, the two smart meters on the lower left are also out of power, but they are connected to the same section of low-voltage distribution line, so there is a possibility of damage to the low-voltage distribution line.

In the example shown in FIG. 4, the blackout state of the high voltage distribution line is also illustrated, but the blackout state of the high voltage distribution line may not be illustrated and the position of the high voltage distribution line may be illustrated. In this case as well, the user can grasp the relationship between the blackout state of each smart meter and the high-voltage distribution line and the low-voltage distribution line, which makes it easier to estimate the cause of the blackout. As described above, in the present embodiment, since estimation of the cause of a power failure can be supported, users such as administrators and workers can promptly take measures to restore the power failure according to the estimated cause. It can be carried out.

As shown in FIG. 4, in the first display, the location of each power outage customer can be grasped in detail, but the displayed range is narrow. For this reason, when the range in which the power failure is assumed to occur cannot be narrowed down, the user cannot appropriately specify the display range information in the display specification information, and it takes time to search for the location where the power failure occurs. may be required. For this reason, for example, when the power outage information providing system 1 of the present embodiment performs the second display that displays the number of power outages in the designated area to display a wider range than the first display, the user makes it easier to grasp the approximate power outage status. That is, the user can determine the display range information in the display designation information for performing the above-described first display based on the content displayed by the second display, and input it to the display terminal 2. Display range information for the first display can be set appropriately.

FIG. 5 is a flow chart showing an example of a processing procedure in the power outage information providing device 3 when the second display is performed according to the present embodiment. As shown in FIG. 5, the power outage information providing device 3 acquires the display designation information including the aggregation unit (step S11). Specifically, as in step S1, the transmitting/receiving unit 31 receives the display designation information from the display terminal 2 to acquire the display designation information, and outputs the acquired display designation information to the display data generation unit 33. The designation information includes the aggregation unit in addition to the display range information described above. Aggregation unit is a unit for aggregating the number of power outage customers, and may be specified by prefecture, municipality, etc., or may be a place name such as A city X town, which is further divided within a municipality. Alternatively, it may be an address such as 1-chome, X-cho, A city.

Next, the power outage information providing device 3 acquires the facility data, map data, and SM measurement data of the area corresponding to the display designation information (step S12). Specifically, the display data generation unit 33 generates a data acquisition request requesting acquisition of facility data, map data, and SM measurement data corresponding to the area indicated by the display range information in the display designation information, and sends the data acquisition request to the data acquisition unit 32. The data acquisition unit 32 transmits the data acquisition request to the data storage device 4 . The data acquisition unit 32 receives data corresponding to the data acquisition request from the data storage device 4 and outputs the data to the display data generation unit 33 . At this time, the data storage device 4 transmits the latest data among the facility data, the map data and the SM measurement data to the power outage information providing device 3 respectively.

Next, the power outage information providing device 3 uses the acquired SM measurement data to determine a consumer who is estimated to have a power outage (step S13). The processing of step S13 is the same as that of step S3.

Next, the power outage information providing device 3 tallies up the number of consumers who are estimated to have power outages for each aggregation unit (step S14). Specifically, the display data generation unit 33 totalizes the number of consumers who are estimated to have power outages for each total unit using the determination result of step S13.

Next, the power outage information providing device 3 generates display data based on the tabulated result, the acquired map data and the facility data (step S15). Specifically, the display data generation unit 33 generates display data based on the tabulation result of step S14 and the map data and facility data acquired in step S12, and outputs the display data to the transmission/reception unit 31. FIG. Step S5 is similar to the example described above.

In this way, the display data generation unit 33 counts the number of smart meters with power outages for each count unit, generates count result display data for displaying information indicating the count result for each count unit, and transmits and receives the count result display data. The unit 31 may transmit the tallied result display data to the display terminal 2 .

FIG. 6 is a diagram showing an example of a display screen displayed by the second display of this embodiment. In the example shown in FIG. 6, the aggregation unit is a town unit obtained by dividing a city. In the example shown in FIG. 6, the number of consumers who are assumed to have power outages is displayed for each town, which is a unit of aggregation. can be grasped. In the example shown in FIG. 6, power outages occur in Towns D, Town F, and Town G, so the user can specify these areas in order and check the details on the first display. can be presumed to be the cause of In addition, since the possibility of a large-scale failure occurring in an area with a larger number of cases is higher, the user may perform the first display in order from the area with a larger number of cases to check the details. In addition, in FIG. 6, the display is performed in units of towns, which are obtained by dividing the city. , select municipalities to be displayed using the contents displayed by the second display, specify the selected municipalities as the display range, and perform the second display. good.

Further, for example, in a state where the screen shown in FIG. A third display may be performed in which the power outage information is displayed as a list. That is, the user inputs display designation information designating information for instructing the display terminal 2 to perform list display and display range information indicating the range of the list display, and the display terminal 2 supplies the display designation information to the power outage information. Send to device 3. The power outage information providing device 3 creates a list based on the display designation information, generates display data for displaying the list, and transmits the display data to the display terminal 2 .

FIG. 7 is a diagram showing an example of a display screen displayed by the third display of this embodiment. In the example shown in FIG. 7, the displayed list includes SMID, address, latitude, longitude, connected power line, and power outage status. When the transmitting/receiving unit 31 receives the display designation information indicating the list display, the display data generating unit 33 extracts the SMID, the address, the latitude, the longitude, and the connection distribution line from the above equipment data, By adding the power failure state to the extracted data based on the determination result of step S13 described above, a list can be generated, and display data for displaying the list can be generated. In this way, the display data generation unit 33 generates a list in which the information indicating the installation position of each smart meter and the information indicating whether or not there is a power outage is shown as text, and displays the list for displaying the list. data may be generated.

For example, after causing the second display, the user may display a list of regions where power outages occur, and confirm the list to determine the display range in the first display.

As described above, by using not only the first display but also at least one of the second display and the third display in combination, the user can efficiently grasp the location of the power failure and estimate the cause of the power failure. can be done.

Next, the hardware configuration of the power failure information providing device 3 of this embodiment will be described.
