The input unit 114 may include any input interface such as a USB (Universal Serial Bus) port. The input unit 114 inputs various commands for starting the execution of the processing in the information processing apparatus 100 to the processing unit 112 in response to the detection result of the input operation by the user.

[0014] The communication unit 115 can be configured to include any network interface. The communication unit 115 can be connected to, for example, a LAN (Local Area Network), a WAN (Wide Area Network), the Internet, an intranet, a telephone line, an optical fiber overhead ground wire (OPGW: composite fiber OPtical overhead Grand Wire), a mobile communication network, a combination of some or all of these, and in addition, a telecommunication network including a wireless communication network, an optical communication network, and any network using some or all of these, as long as it can transmit various data and various information by transmitting and receiving communication signals. In this embodiment, the communication unit 115 performs communication capable of acquiring measurement data 200. The measurement data 200 is stored, for example, in a file in a predetermined format such as a CSV (Comma Separated Value) file at each business office of an electric power company. The measurement data 200 acquired by the communication unit 115 is stored in the storage unit 111. Note that the measurement data 200 may be acquired by a reading device included in the input unit 114 or the like.

[0015] As shown in FIG. 2, the storage unit 111, which is an example of the storage content configuration, can store a study support program 120, study support information 130, various programs including these, and various information. The study support program 120 is a processing program executable by the processing unit 112, and can support the study of setting values corresponding to the voltage adjustment device to be set. The study support information 130 is various information that can be used or generated in association with the execution of the study support program 120 by the processing unit 112.

[0016] The study support program 120 may be composed of a plurality of program modules including a menu display module 121, a display data creation module 122, a graph display module 123, and a setting value confirmation display module 124. The menu display module 121 enables the display of a setting value study menu screen on the display device of the output unit 113 or the like. The display data creation module 122 enables the creation of display data for study support that can be used to study the setting values of the voltage adjustment device based on the input content on the setting value study menu screen or the like. The graph display module 123 enables the display of a graph display screen on the display device of the output unit 113 or the like as study information corresponding to the setting values of the voltage adjustment device. The setting value confirmation display module 124 enables the display of a voltage setting value confirmation screen on the display device of the output unit 113 or the like for the current or changed setting values of the voltage adjustment device.

[0017] The study support information 130 may be composed of a plurality of types of information including target designation information 131, device selection information 132, measurement-related information 133, regulation determination information 134, and various display information 135. The target designation information 131 is designation information indicating the voltage adjustment device to be the setting target. The device selection information 132 is selection information corresponding to the device that becomes a voltage acquisition device among the plurality of devices installed on the distribution system line. The measurement-related information 133 is information related to measured values including measurement data of feeder current and measurement data in the voltage adjustment device and the voltage acquisition device. The regulation determination information 134 is determination information that can indicate whether it is within the range of the voltage regulation value when studying the setting values of the voltage adjustment device. The various display information 135 is display information including display data by the display device of the output unit 113 or the like.

[0018] As shown in the flowchart of FIG. 3, the processing unit 112 of the information processing apparatus 100 can execute setting study support processing. The setting study support processing can be executed by the processing unit 112 reading out the study support program 120 stored in the storage unit 111. The study support program 120 uses various display information 135 stored in the storage unit 111 to perform screen display on a display device of the output unit 113 and supports consideration of voltage setting by a feedback method using measurement data from a voltage acquisition device.

[0019] In the setting study support processing, the processing unit 112 outputs, as a menu screen display (step S101), a setting value study menu screen so that it can be displayed on a display device of the output unit 113. In this case, the processing unit 112 enables the setting value study menu screen to be displayed on a display device of the output unit 113 by the menu display module 121 of the study support program 120. The setting value study menu screen may be displayed using the menu screen display information included in the various display information 135 of the study support information 130.

[0020] When the processing unit 112 is displaying the setting value study menu screen by the menu display module 121 of the study support program 120, it enables the input of designation information of the voltage adjustment device to be set in response to an input command such as the user operating the input unit 114. For example, the designation information may be anything that indicates an identification number or the like for designating a voltage adjustment device, such as an automatic voltage adjustment device to be set. The setting value study menu screen that can be displayed in step S101 enables the input of designation information of the voltage adjustment device to be set. In this way, the processing unit 112 that executes step S101 of the setting study support processing is an example of designation means that enables the input of designation information of the voltage adjustment device to be set, together with the input unit 114 operated by the user and the display device of the output unit 113 that displays the setting value study menu screen.

[0021] When the processing unit 112 displays a setting value examination menu screen by the menu display module 121 of the examination support program 120, it enables input of selection information corresponding to devices that serve as voltage acquisition devices among a plurality of devices installed on the power distribution system line in response to an input command due to the user operating the input unit 114 or the like. For example, the selection information may be an identification number or the like for selecting, as a voltage acquisition device, another voltage regulator installed on the load side of the automatic voltage regulator to be set, a switch with a sensor, an automatic reclosing device, a phasor measurement unit (PMU), a telemeter (TM), or other power flow measurement devices, or any measurement device capable of measuring electrical quantities including the voltage at the measurement point of the power distribution system. The setting value examination menu screen that can be displayed in step S101 enables input of selection information corresponding to devices that serve as voltage acquisition devices among a plurality of devices installed on the power distribution system line. In this way, the processing unit 112 that executes step S101 of the setting examination support process is an example of a selection means that enables input of selection information corresponding to a voltage acquisition device, together with the input unit 114 operated by the user and the display device of the output unit 113 that displays the setting value examination menu screen.

[0022] Next, as input result capture (step S102), various information and measurement data input on the setting value examination menu screen displayed in step S101 are captured and made storable in the storage unit 111. For example, when the setting value examination menu screen is displayed, the processing unit 112 may generate or acquire target specification information 131, device selection information 132, measurement-related information 133, all or part of these, as long as they can be stored in the storage unit 111, in response to the user operating the input unit 114 or the like.

[0023] The target specification information 131 captured in step S102 is the specification information of the voltage regulator input on the setting value consideration menu screen. The device selection information 132 captured in step S102 is the selection information of the voltage acquisition device input on the setting value consideration menu screen. The measurement-related information 133 captured in step S102 may include the time-series measurement data of the voltage regulator corresponding to the specification information and the time-series measurement data of the voltage acquisition device corresponding to the selection information among the communication data 200 that can be acquired by the communication unit 115. Each device that can be selected as the voltage acquisition device only needs to be able to generate measurement data indicating the measurement results of electrical quantities including voltage at a predetermined time interval such as every three minutes. Further, the measurement-related information 133 may include, as the measurement data of the feeder current, the first measurement data corresponding to the maximum current day and the second measurement data corresponding to the minimum current day. These measurement data only need to be acquirable in response to an acquisition command such as when the user operates the input unit 114 while the processing unit 112 is displaying the setting value consideration menu screen by the menu display module 121 of the consideration support program 120. Therefore, the processing unit 112 that executes step S102 of the setting consideration support process is an example of an acquisition means capable of acquiring various measurement data together with the input unit 114 operated by the user and the display device of the output unit 113 that displays the setting value consideration menu screen.

[0024] Based on the input result captured in step S102, the processing unit 112 enables the display of the determination result of the voltage specified value and the graphical display of the time transition of electrical quantities as the current setting value correspondence display (step S103). When displaying the determination result of the voltage specified value, the processing unit 112 enables the determination of whether the output voltage of the voltage regulator, the reaching voltage of the voltage acquisition device, etc. are within the range of the specified value by the display data creation module 122 of the consideration support program 120. To perform these determinations, the display data creation module 122 calculates the actual voltage drop and enables the determination of the upper and lower limit values of the output voltage in the voltage regulator, the upper and lower limit values on the low voltage side of the reaching voltage, etc. Corresponding to these upper and lower limit values, the specified discrimination information 134 may be generated and stored in the storage unit 111 if possible.

[0025] The calculation of the actual voltage drop subtracts the reaching side high voltage converted voltage from the output voltage on the power supply side, and enables the calculation using the voltage drop of the high voltage load management including the case where the voltage drop to the end is also considered. For example, taking the output voltage V in a voltage regulator such as an automatic voltage regulator, the transformer tap Tt, the logged voltage Vr of the voltage acquisition device, the voltage drop e from the voltage acquisition device to the end, the current per unit time Ih, and the annual maximum current Imax, the voltage drop E is calculated by the voltage drop calculation formula of Equation (1). E = V - (Tt / 105 × Vr) + e(Ih / Imax) (1) Thus, the value of the voltage drop E can be obtained using the output voltage V of the voltage regulator, the transformer tap Tt, the logged voltage Vr of the voltage acquisition device, the voltage drop e from the voltage acquisition device to the end, the current per unit time Ih, and the annual maximum current Imax.

[0026] In order to determine the upper limit value and the lower limit value of the output voltage in a voltage regulating device, for example, using time-series measurement data that becomes log data in a voltage regulating device such as an automatic voltage regulator, the output voltage is calculated from the compensation voltage by line voltage drop compensation (LDC) calculation. Then, the upper limit value and the lower limit value of the output voltage corresponding to the dead band rate are determined. This makes it possible to consider setting values that also correspond to the leading power factor.

[0027] For example, as the reference voltage Vk, the passing current I, the power factor cosθ, the resistance component r of the setting impedance, and the reactance component x of the setting impedance in an automatic voltage regulator, the output voltage Vs of the automatic voltage regulator is calculated by the output voltage calculation formula of Equation (2). Vs = Vk + √3I(rcosθ + xsinθ) (2) In this way, the output voltage Vs of the automatic voltage regulator can be obtained using the reference voltage Vk, the passing current I, the power factor cosθ, the resistance component r of the setting impedance, and the reactance component x of the setting impedance in the automatic voltage regulator.

[0028] Also, for example, as the dead band rate f [%], the dead band upper limit voltage Vh is calculated as the upper limit value in the output voltage by the output upper limit value calculation formula of Equation (3). Vh = Vs + 6700×f / 100 (3) In this way, the upper limit voltage Vh in the output voltage can be obtained using the output voltage Vs of the automatic voltage regulator and the dead band rate f. Similarly, the lower limit voltage Vl in the output voltage can be obtained using the output voltage Vs of the automatic voltage regulator and the dead band rate f. The processing unit 112 that determines the upper limit voltage Vh and the lower limit voltage Vl in the output voltage can be included as an example of the range determination means that can determine the range of the voltage specified value using the time-series measurement data in the voltage regulating device.

[0029] Using the above calculation results, the upper limit value and the lower limit value on the low-voltage side of the reach voltage can be determined. For example, taking the upper limit voltage Vh in the transmission voltage calculated by Equation (3) as the high-voltage upper limit value, the voltage drop E calculated by Equation (1) as the high-voltage voltage drop, the Tr tap Tt, and the voltage drop Eh for each low-voltage time zone, the low-voltage upper limit value VLh is calculated as the upper limit value on the low-voltage side in the reach voltage by the low-voltage upper limit value calculation formula of Equation (4). VLh=(Vh+E)×105 / Tt-Eh (4) In this way, the upper limit voltage VLh on the low-voltage side in the reach voltage can be obtained using the upper limit voltage Vh in the transmission voltage, the voltage drop E, the Tr tap Tt, and the voltage drop Eh for each low-voltage time zone. Similarly, the lower limit voltage VLl, which is the lower limit value on the low-voltage side in the reach voltage, can be obtained using the lower limit voltage Vl in the transmission voltage, the voltage drop E, the Tr tap Tt, and the voltage drop Eh for each low-voltage time zone. The processing unit 112 that determines the upper limit voltage VLh and the lower limit voltage VLl on the low-voltage side in the reach voltage can be included as an example of range determination means capable of determining the range of the voltage specified value using the voltage drop Eh for each low-voltage time zone.

[0030] The processing unit 112 can display a voltage setting value confirmation screen on a display device of the output unit 113 or the like by the setting value confirmation display module 124 of the examination support program 120. The voltage setting value confirmation screen that can be displayed in step S103 enables the result of determining whether the transmission voltage and the reach voltage are within the range of the specified value to be confirmed by the specified discrimination information 134 as an example of examination information corresponding to the current setting value of the voltage adjustment device. In this way, the processing unit 112 that executes step S103 of the setting examination support process is an example of first current output means that can output, together with a display device of the output unit 113 that displays the voltage setting value confirmation screen, determination information on whether it is within the range of the voltage specified value corresponding to the current setting value of the voltage adjustment device.

[0031] In addition, the processing unit 112 enables the graph display module 123 of the examination support program 120 to display a graph display screen on the display device of the output unit 113 or the like. The graph display screen that can be displayed in step S103, as another example of the examination information corresponding to the current setting value of the voltage adjustment device, uses the measurement data captured in step S102 and included in the measurement-related information 133 to enable the graph display of the time transition of electrical quantities. Therefore, the processing unit 112 that executes step S103 of the setting examination support process also serves as an example of a second current output means that can output the time transition of electrical quantities in a graph display manner corresponding to the current setting value of the voltage adjustment device, together with the display device of the output unit 113 that displays the graph display screen. The processing unit 112 including the first current output means and the second current output means serves as an example of an output means that can output the examination information corresponding to the setting value of the voltage adjustment device in a displayable manner, together with the display device of the output unit 113 or the like.

[0032] After the display in step S103 is performed, it is determined whether the end condition is satisfied (step S104). For example, when the voltage setting value confirmation screen or the graph display screen is displayed, the processing unit 112 may determine that the end condition is satisfied in response to an end command by an operation of the input unit 114 by the user. When the end condition is satisfied (step S104; Yes), the setting examination support process ends.

[0033] When the end condition is not satisfied (step S104; No), as the changed setting value input (step S105), it is possible to input the changed setting value on the voltage setting value confirmation screen. When the processing unit 112 displays the voltage setting value confirmation screen by the setting value confirmation display module 124 of the examination support program 120, the changed setting value can be input in response to a change command by the user operating the input unit 114 or the like. In addition, it is possible to change the setting of the voltage control method. The changed setting value input on the voltage setting value confirmation screen may be stored in the storage unit 111, either included in the measurement-related information 133 or as information separate from the measurement-related information 133, as long as it can be stored.

[0034] The voltage setting value confirmation screen displayed in step S105 enables the input of setting change information when changing the setting value of the voltage adjustment device. In this way, the processing unit 112 that executes step S105 of the setting consideration support process, together with the input unit 114 operated by the user and the display device of the output unit 113 that displays the voltage setting value confirmation screen, is an example of a change means that enables the input of setting change information when changing the setting value of the voltage adjustment device to be set.

[0035] Based on the changed setting value input in step S105, the processing unit 112 can display the determination result of the voltage specified value or graphically display the time transition of electrical quantities as the changed setting value corresponding display (step S106). In this case, by executing the same processing as the current setting value corresponding display in step S103 for the changed setting value, it is possible to determine whether the output voltage of the voltage adjustment device, the reach voltage of the voltage acquisition device, etc. are within the range of the specified value. The processing unit 112 can display the voltage setting value confirmation screen by the setting value confirmation display module 124 of the consideration support program 120, and can display the graph display screen by the graph display module 123 of the consideration support program 120.

[0036] The voltage setting value confirmation screen displayed in step S106 enables confirmation of the result of determining whether the transmitted voltage and the reached voltage are within the specified value range, as an example of the consideration information corresponding to the changed setting value of the voltage adjustment device. The graph display screen displayed in step S106 enables graph display of the time transition of electrical quantities, as another example of the consideration information corresponding to the setting value after the change of the voltage adjustment device. In this way, the processing unit 112 that executes step S106 of the setting consideration support process is an example of a first change output means that, together with the display device of the output unit 113 that displays the voltage setting value confirmation screen, outputs in a displayable manner the determination information as to whether it is within the range of the voltage specified value corresponding to the changed setting value of the voltage adjustment device. Also, the processing unit 112 that executes step S106 of the setting consideration support process is an example of a second change output means that, together with the display device of the output unit 113 that displays the graph display screen, outputs in a graph-displayable manner the time transition of electrical quantities corresponding to the changed setting value of the voltage adjustment device. The processing unit 112 including the first change output means and the second change output means is an example of an output means that, together with the display device of the output unit 113, outputs in a displayable manner the consideration information corresponding to the setting value of the voltage adjustment device.

[0037] After the display by step S106, it is determined whether there is a re-change command (step S107). For example, the processing unit 112 may determine the presence or absence of a re-change command based on an operation of the input unit 114 by the user. When there is a re-change command (step S107; Yes), the process returns to step S105 to enable input of a new changed setting value. When there is no re-change command (step S107; No), the setting consideration support process ends.

[0038] The setting value consideration menu screen shown by the configuration example 200 in FIG. 4 includes a target display area A01, a selected display area A02, an acquired display area A03, a consideration display area A04, a detailed display area A05, and these multiple display areas.

[0040] The selection display area A02 is a display area that enables display and input of information for selecting a voltage acquisition device. The selection display area A02 includes a selection explanation display area and a selection information input area. The selection explanation display area only needs to be configured to enable display of selection explanation information that is explanation information when selecting a voltage acquisition device. The selection information input area only needs to be configured to enable input of information for selecting a voltage acquisition device.

[0041] The selection explanation display area of the selection display area A02 only needs to be able to display multiple types of explanation information as selection explanation information. For example, the selection explanation information includes first selection explanation information indicating a message of "Automatic section management table printing". Further, the selection explanation information includes second selection explanation information indicating a message of "Selecting target devices in high-voltage load management" and a message of "Selecting AD, Re, SVR near tap change points or ends and end locations". Furthermore, the selection explanation information includes third selection explanation information indicating four messages: a message of "LLsMap: Checking Tr taps of voltage acquisition devices", a message of "SVR: Periphery of primary side, switch: Power side · Load side", a message of "Selecting AD, TRs, TVs, SEN, TM near tap change points or ends", and a message of "When considering the end, input the voltage drop from the voltage acquisition device to the end in voltage load management".

[0042] The acquisition display area A03 is a display area that enables the display and reading of information for acquiring measurement data such as voltage values in a voltage acquisition device. The acquisition display area A03 includes an acquisition description display area and an acquisition information setting area. The acquisition description display area may be configured to be able to display acquisition description information that serves as explanatory information when acquiring measurement data. The acquisition information setting area may be configured to be able to set and read measurement data in the voltage acquisition device.

[0043] The acquisition description display area of the acquisition display area A03 only needs to be able to display multiple types of description information as acquisition description information. For example, the acquisition description information includes first acquisition description information indicating a message of "Last year, the maximum and minimum current occurrence dates of the feeder were investigated using the actual load of the automation system (excluding the distributed power part)". Also, the acquisition description information includes second acquisition description information indicating a message of "Obtaining the maximum and minimum daily data logs of the SVR and voltage acquisition device to be set" and a message of "Creating a 24-hour data log csv of the maximum and minimum days of the target device from the backup PC and saving it in the same folder as the review file". Furthermore, the acquisition description information includes third acquisition description information indicating a message of "Reading the maximum and minimum data using the [Set SVR csv read] button of the voltage acquisition device and the [No. read] button".

[0044] The review display area A04 is a display area that enables the display of information for reviewing the setting values of the voltage regulator and allows the selection of a low-voltage demand section. The review display area A04 includes a review description display area and a section selection setting area. The review description display area may be configured to be able to display review description information that serves as explanatory information when reviewing the setting values of the voltage regulator. The section selection setting area may be configured to be able to select and input codes corresponding to a plurality of sections prepared in advance as low-voltage demand sections.

[0045] The consideration explanation display area of the consideration display area A04 only needs to be able to display multiple types of explanation information as consideration explanation information.

The detailed information input area may be configured to be able to input detailed drop information for correcting the low-voltage voltage drop.

[0048] The detailed explanation display area of the detailed display area A05 only needs to be able to display the explanation information that is the detailed explanation information. For example, the detailed explanation information shows a message "In AD and TRs, due to the Tr utilization rate and the low-voltage line voltage drop, the high-voltage conversion error becomes large, so input is required to correct the low-voltage voltage drop."

[0057] As shown in Example 212 in FIG. 7, the acquisition information setting area of the acquisition display area A03 includes a feeder current input field A31 and a measurement data reading field A32. A processing unit 112, which is an example of an acquisition means, etc., can acquire time-series measurement data in the voltage adjustment device and the voltage acquisition device together with the measurement data of the feeder current by an acquisition information setting area that includes the feeder current input field A31 and the measurement data reading field A32 and is arranged together with the acquisition explanation display area in the acquisition display area A03.

[0058] The feeder current input field A31 may be configured to include cells that are a plurality of input fields for inputting measurement data of the feeder current, together with a message of "feeder maximum current day" and a message of "feeder minimum current day". The maximum current input field provided along with the message of "feeder maximum current day" can acquire first current measurement data regarding the current value at the maximum load in response to an input command such as the user operating the input unit 114. The minimum current input field provided along with the message of "feeder minimum current day" can acquire second current measurement data regarding the current value at the minimum load in response to an input command such as the user operating the input unit 114.

[0059] The measurement data input in the feeder current input field A31 can be stored in the storage unit 111 included in the measurement related information 133. For example, the maximum current information including the date and the first current measurement data input corresponding to the message of "feeder maximum current day" may be included in the measurement related information 133 and stored in the storage unit 111. The minimum current information including the date and the second current measurement data input corresponding to the message of "feeder minimum current day" may be included in the measurement related information 133 and stored in the storage unit 111.

[0060] Therefore, a processing unit 112 or the like, which is an example of the acquisition means, can constitute an example of the first acquisition means by outputting the maximum current input field among the feeder current input fields A31 included in the acquisition display area A03 so as to be displayable and enabling the acquisition of first current measurement data corresponding to the maximum value of the feeder current.

When an operation of pressing the button display B01 is detected by the input unit 114, it is possible to select a CSV file in which the measurement data of the automatic voltage adjustment device to be set is stored. Thereby, it is possible to acquire the time-series measurement data in the voltage adjustment device. The second data reading field includes a plurality of button displays B11 to B19 where texts from "No1 reading" to "No9 reading" are displayed corresponding to the device number display field A22 in the device number display area of the selection information input area of the selection display area A02. When an operation of pressing any one of the button displays B11 to B19 is detected by the input unit 114, it is possible to select a CSV file in which the measurement data of the device selected as the voltage acquisition device is stored. Thereby, it is possible to acquire the time-series measurement data in the voltage acquisition device. Therefore, in the acquisition information setting area of the acquisition display area A03, a processing unit 112 or the like that outputs the measurement data reading field A32 so as to be displayable and enables the acquisition of measurement data corresponding to the pressing operation of the button display is an example of an acquisition means capable of acquiring the time-series measurement data in the voltage adjustment device and the voltage acquisition device.

[0062] When a processing unit 112 or the like, which is an example of an acquisition means, can acquire various measurement data, in the acquisition description display area included in the acquisition display area A03 of the configuration example 200 shown in FIG. 4, it outputs the acquisition description information including the first acquisition description information to the third acquisition description information so as to be displayable. Such a processing unit 112 is an example of an acquisition output means that outputs the acquisition description information so as to be displayable in correspondence with the measurement data that can be acquired by the acquisition means, together with a display device of an output unit 113 that displays a setting value consideration menu screen.

[0063] The classification selection setting area of the consideration display area A04 shown by the display example 213 in FIG. 8 includes a classification code display column A41 and a classification code input column A42.

[0064] The classification code display column A41 is arranged corresponding to the first consideration description information in the consideration description display area, and may be configured to include cells that are a plurality of display columns for displaying the codes of "general household", "factory area", "general + PV", and "factory + PV" prepared as low-voltage demand classifications as "1" to "4" respectively. In this case, the first code description information may be displayed so that an area with a large amount of low-voltage sunlight selects the code of "3" or "4" at the minimum load time.

[0065] The classification code input column A42 may be configured to include cells that are a plurality of input columns for selecting and inputting any one of the codes "1" to "4" of the codes displayed in the classification code display column A41 corresponding to the items of "maximum load time" and "minimum load time".

[0066] The detailed information input area of the detailed display area A05 shown by the display example 214 in FIG. 9 includes a detailed item display column A51, a device number display column A52, and a detailed information input column A53.

Among these, the items of Tr capacity, Tr utilization rate, low-voltage line voltage drop, and maximum voltage drop are provided corresponding to each of the power supply side and the load side.

[0069] The detailed information input column A53 may be configured to include cells that are a plurality of input columns for inputting information of the device specified for each device number in the device number display column A52 corresponding to the display contents in the plurality of display columns constituting the detailed item display column A51. The information input in the detailed information input column A53 can be stored in the storage unit 111 as detailed drop information included in the measurement-related information 133.

[0070] The graph display screen in which the display example 220 is shown in FIG. 10 includes the first current graph display area B01 to the fourth current graph display area B04, which are four display areas capable of graphically displaying the time transition of electrical quantities corresponding to the current setting value of the voltage regulator. The first current graph display area B01 displays a time transition graph at the upper limit value of the voltage directly below Tr corresponding to the current setting value and the minimum load. The second current graph display area B02 displays a time transition graph of the voltage drop of the voltage acquisition device corresponding to the current setting value and the minimum load. The third current graph display area B03 displays a time transition graph of the active current and the reactive current corresponding to the current setting value and the minimum load. The fourth current graph display area B04 displays a time transition graph of the power factor corresponding to the current setting value and the minimum load. Note that the graph display screen may be capable of graphically displaying the time transition of the same electrical quantities as at the minimum load corresponding to the current setting value and the maximum load. The processing unit 112 and the display device of the output unit 113, which are examples of the second current output means, only need to be capable of graphically displaying the time transition of electrical quantities corresponding to the current setting value of the voltage regulator in the first current graph display area B01 to the fourth current graph display area B04 included in the graph display screen of the display example 220 and any other graph display area.

[0071] The graph display area of the graph display screen corresponding to the current setting value and the maximum load can display a time-series graph that is an example of the first consideration information at the maximum load, corresponding to the maximum value of the feeder current for which the first current measurement data was acquired. In this case, the date on which the first current measurement data was acquired is specified from the maximum current information, and using the time-series measurement data of the voltage adjustment device and the voltage acquisition device acquired corresponding to that date, it suffices that the time-series of the electrical quantities at the current setting value and the maximum load can be graphically displayed. Therefore, a processing unit 112, which is an example of the output means, outputs in such a manner that a time-series graph can be displayed in the graph display area of the graph display screen corresponding to the current setting value and the maximum load, thereby configuring an example of the first consideration output means that can output and display the first consideration information at the maximum load corresponding to the maximum value of the feeder current for which the first current measurement data was acquired.

[0072] The graph display area of the graph display screen corresponding to the current setting value and the minimum load can display a time-series graph that is an example of the second consideration information at the minimum load, corresponding to the minimum value of the feeder current for which the second current measurement data was acquired. In this case, the date on which the second current measurement data was acquired is specified from the minimum current information, and using the time-series measurement data of the voltage adjustment device and the voltage acquisition device acquired corresponding to that date, it suffices that the time-series of the electrical quantities at the current setting value and the minimum load can be graphically displayed. Therefore, a processing unit 112, which is an example of the output means, outputs in such a manner that a time-series graph can be displayed in the graph display area of the graph display screen corresponding to the current setting value and the minimum load, thereby configuring an example of the second consideration output means that can output and display the second consideration information at the minimum load corresponding to the minimum value of the feeder current for which the second current measurement data was acquired.

[0073] The voltage setting value confirmation screen shown by the display example 230 in FIG. 11 can display the setting content and the determination result corresponding to the current setting value and the changed setting value of the voltage adjustment device. The voltage setting value confirmation screen of the display example 230 includes a current setting display column B11, a changed setting display column B12, and a determination result display column B13.

[0074] The current setting display column B11 may be configured to include cells that are a plurality of display columns for displaying the setting contents corresponding to the current setting values of the voltage regulator. For example, the current setting display column B11 includes a plurality of current tap value display columns that show the tap value of the voltage regulator corresponding to each time zone from 0:00 to 23:00 of a day at one-hour intervals. Note that the current tap value display column may display the current tap value indicated by the tap value data included in the time-series measurement data in the voltage regulator obtained using the button display B01 in the first data reading column in the measurement data reading column A32 shown in FIG. 7. Alternatively, the current tap value may not be displayed. In addition, the current setting display column B11 includes a plurality of current setting display columns that show the setting contents corresponding to each item such as the rated capacity, reference voltage, resistance component and reactance component of the setting impedance, operating time, dead band, standard deviation, corresponding to the current setting value of the voltage regulator. Further, the current setting display column B11 includes a current control display column that shows the current voltage control method in the voltage regulator.

[0075] The post-change setting display column B12 includes a plurality of post-change tap value display columns and a plurality of post-change setting display columns. The post-change tap value display columns of the post-change setting display column B12 show the tap value of the voltage regulator corresponding to the post-change setting value corresponding to the same time zones as the current tap value display columns of the current setting display column B11. The post-change setting display columns of the post-change setting display column B12 show the setting contents corresponding to each item similar to the current setting display columns of the current setting display column B11 corresponding to the post-change setting value of the voltage regulator. Further, the post-change setting display column B12 includes a post-change control display column that shows the post-change voltage control method in the voltage regulator.

[0076] The determination result display column B13 includes a plurality of current time zone determination display columns and changed time zone determination display columns that show, corresponding to the current setting value and the changed setting value of the voltage regulator, whether the transmitted voltage and the reached voltage are within the specified value range, corresponding to the same time zones as the current tap value display column in the current setting display column B11 and the changed tap value display column in the changed setting display column B12. Display devices such as the processing unit 112 and the output unit 113, which are examples of the first current output means, output, in the current time zone determination display column of the determination result display column B13, determination information on whether it is within the voltage specified value range corresponding to the current setting value of the voltage regulator, in a displayable manner. Display devices such as the processing unit 112 and the output unit 113, which are examples of the first change output means, output, in the changed time zone determination display column of the determination result display column B13, determination information on whether it is within the voltage specified value range corresponding to the changed setting value of the voltage regulator, in a displayable manner.

[0077] When outputting in a displayable manner a voltage setting value confirmation screen including the determination result display column B13, the processing unit 112, which is an example of the range determination means, can determine the upper limit voltage Vh, which is the upper limit value of the transmitted voltage, and the lower limit voltage Vl, which is the lower limit value, among the voltage specified values, using the time-series measurement data in the voltage regulator. The time-series measurement data in the voltage regulator can be obtained as a CSV file selected in the first data reading column of the measurement data reading column A32 in the acquisition information setting area of the acquisition display area A03 where the display example 212 is shown in FIG. 7. The processing unit 112 and the like, which are examples of the acquisition means, output the acquisition display area A03 including the acquisition information setting area in a displayable manner, making it possible to acquire the time-series measurement data in the voltage regulator. Therefore, the processing unit 112, which is an example of the range determination means, can determine the upper limit value and the lower limit value of the transmitted voltage using the time-series measurement data in the voltage regulator acquired by the acquisition means.

[0078] Also, when outputting to display a voltage setting value confirmation screen including a determination result display column B13, a processing unit 112, which is an example of a range determination means, can determine an upper limit voltage VLh, which is the upper limit value on the low-voltage side at the reached voltage, and a lower limit voltage VLl, which is the lower limit value, using the voltage drop Eh by low-voltage time band. The voltage drop Eh by low-voltage time band may be determined using the classification code of the low-voltage demand classification and the detailed drop information. The classification code of the low-voltage demand classification can be input as the code selected in the classification code input column A42 in the classification selection setting area of the consideration display area A04 where the display example 213 is shown in FIG. 8. The detailed drop information can be input in the detailed information input column A53 in the detailed display area A05 where the display example 214 is shown in FIG. 9. A processing unit 112, etc., which outputs the classification code input column A42 to be displayable in the classification selection setting area of the consideration display area A04 and enables input of the classification code corresponding to the operation detected by the input unit 114, is an example of a classification setting means that can input a classification code indicating the low-voltage demand classification corresponding to the maximum load time and the minimum load time. A processing unit 112, etc., which outputs the detailed information input column A53 to be displayable in the detailed information input area of the detailed display area A05 and enables input of the detailed drop information corresponding to the operation detected by the input unit 114, is an example of a correction setting means that can input the detailed drop information for correcting the low-voltage voltage drop. Therefore, the processing unit 112, which is an example of a range determination means, can determine the upper limit value and the lower limit value on the low-voltage side of the reached voltage using the classification code input by the classification setting means and the detailed drop information input by the correction setting means.

[0079] The graph display screen showing the display example 240 in FIG. 12 includes four display areas, from the first changed graph display area B21 to the fourth changed graph display area B24, where the time progression of electrical quantities can be graphically displayed corresponding to the changed setting value of the voltage regulator. The first changed graph display area B21 displays a time progression graph at the upper limit value of the voltage directly below Tr corresponding to the changed setting value and the minimum load. The second changed graph display area B22 displays a time progression graph of the low-voltage terminal voltage corresponding to the changed setting value and the minimum load. The third changed graph display area B23 displays a time progression graph at the upper limit value of the voltage directly below Tr corresponding to the changed setting value and the maximum load. The fourth changed graph display area B24 displays a time progression graph of the low-voltage terminal voltage corresponding to the changed setting value and the maximum load. Note that the graph display screen may be able to graphically display the time progression of electrical quantities similar to the current setting value corresponding to the changed setting value and the minimum load or the maximum load. The processing unit 112 and the display device of the output unit 113, which are examples of the second change output means, may display the time progression of electrical quantities corresponding to the changed setting value of the voltage regulator in any other graph display area, from the first changed graph display area B21 to the fourth changed graph display area B24 included in the graph display screen of the display example 240, as long as it is possible.

[0080] The graph display area of the graph display screen corresponding to the changed setting value and the maximum load enables the display of a time-series graph, which is an example of the first consideration information at the maximum load, corresponding to the maximum value of the feeder current for which the first current measurement data is acquired. In this case, the date when the first current measurement data is acquired is specified from the maximum current information, and using the time-series measurement data of the voltage regulator and the voltage acquisition device acquired corresponding to that date, for example, in addition to the passing current and power factor of the voltage regulator, the low-voltage side voltage of the voltage acquisition device, and other measurement results, as well as the changed setting impedance, etc., it suffices that the time-series graph can be displayed in the graph display area of the graph display screen corresponding to the changed setting value and the maximum load. Therefore, a processing unit 112, etc., which is an example of the output means, outputs so as to enable the display of the time-series graph in the graph display area of the graph display screen corresponding to the changed setting value and the maximum load, thereby constituting an example of the first consideration output means that can output so as to enable the display of the first consideration information at the maximum load corresponding to the maximum value of the feeder current for which the first current measurement data is acquired.

[0081] The graph display area of the graph display screen corresponding to the changed setting value and the minimum load enables the display of a time-series graph, which is an example of the second consideration information at the minimum load, corresponding to the minimum value of the feeder current for which the second current measurement data is acquired. In this case, the date when the second current measurement data is acquired is specified from the minimum current information, and using the time-series measurement data of the voltage regulator and the voltage acquisition device acquired corresponding to that date, for example, in addition to the passing current and power factor of the voltage regulator, the low-voltage side voltage of the voltage acquisition device, and other measurement results, as well as the changed setting impedance, etc., it suffices that the time-series graph can be displayed in the graph display area of the graph display screen corresponding to the changed setting value and the minimum load. Therefore, a processing unit 112, etc., which is an example of the output means, outputs so as to enable the display of the time-series graph in the graph display area of the graph display screen corresponding to the changed setting value and the minimum load, thereby constituting an example of the second consideration output means that can output so as to enable the display of the second consideration information at the minimum load corresponding to the minimum value of the feeder current for which the second current measurement data is acquired.

[0082] In the example of considering the setting value, in the first current graph display area B01 of the graph display screen corresponding to the display example 220 in FIG. 10, the automatic reclosing device with the identification number TRs6424 among the voltage acquisition devices exceeds the voltage specified value of 107 [V] in the time period from the time T01 corresponding to 5 o'clock to the time T02 corresponding to 20 o'clock. Also, in the second current graph display area B02, the automatic reclosing device with the identification number TRs6424 shows an increase up to 249 [V], which is the maximum voltage drop transition in this time period. In the third current graph display area B03 and the fourth current graph display area B04, it can be seen that the current and power factor in the same time period have the leading power factor of 0.25 as the maximum, and the phase is very advanced.

[0083] When the reached voltage exceeds the voltage specified value, the life of the device, such as the continuous lighting time of a light bulb, is significantly shorter compared to the rated life. As a specific example, a test sample of a 100V light bulb with a rated power of 40W and a rated life of 1000 hours (approximately 42 days) was used. Comparing the case of lighting it in a normal voltage circuit with an average voltage of 105V and the case of lighting it in a high voltage circuit with an average voltage of 110V, the continuous lighting time was 527 hours (approximately 22 days) in the normal voltage circuit and 316 hours (approximately 13 days) in the high voltage circuit. Such results are also consistent with the power supply voltage characteristics of the light bulb life, and it was confirmed that an increase in voltage also affects the life of the device.

[0084] It should be noted that there seems to be a small error in the translation of the time in the "high voltage circuit" part of item [5]. It should be "316 hours (approximately 13 days)" instead of "316 hours (approximately 31 days)" according to the calculation. 13 days is obtained by dividing 316 hours by 24 hours per day.In the voltage setting value confirmation screen corresponding to the display example 230 in FIG. 11, among the multiple current time zone determination display columns included in the determination result display column B13, an × mark indicating that not all the display columns are within the specified value range corresponding to the current setting value is shown. In this case, in the changed setting display column of the changed setting display column B12, different percentage values from the current setting value are input for the resistance component and the reactance component of the setting impedance. In this example, in order to suppress the voltage corresponding to the leading power factor, the reactance component is greatly changed from 4% to 7%, and the resistance component is changed from 4% to 2%. As a result, the upper and lower limit values could be reduced, but the exceeding of the upper limit value could not be eliminated. Therefore, the voltage control method is changed from program control (PC) to a combination with LDC control. By lowering the reference voltage in the daytime time zone from 6600 [V] to 6540 [V], as shown in the first changed graph display area B21 of the graph display screen corresponding to the display example 240 in FIG. 12, it is within the range of the voltage specified value in all time zones.

[0085] While referring to FIG. 13, as a verification example after the setting consideration, the case where the setting value of the automatic voltage regulator with the identification number TVs6225 is changed will be described. In this case, for the voltage time transition in the voltage acquisition device with the identification number TRs6424 as shown in FIG. 13(A), corresponding to the current setting value before the change, the maximum voltage value was 109 [V], deviating from the upper limit voltage value. On the other hand, with the changed setting value, the maximum voltage value was confirmed to be 107 [V] or less and within the range of the voltage specified value. Also, the result of the voltage measurement performed again at the annual measurement point of the feeder F01 as shown in FIG. 13(B) showed that the maximum voltage value of the measured value was 106.3 [V], and it was confirmed to be within the range of the voltage specified value. It was also confirmed that it was within the range of the voltage specified value in other voltage acquisition devices. In this way, it was confirmed that the feedback-type voltage setting could be supported for consideration and an appropriate setting value could be obtained.

[0086] The present invention may be applied to bus voltage setting. For example, in bank BK01 with a shunt resistor, by using harmonic measurement data, it may be possible to support the consideration of bus voltage setting according to the same calculation principle.

[0087] The graph display screen in which display example 250 is shown in FIG. 14, as a voltage adjustment device, for example, corresponding to the current setting value of a load tap-changing transformer (LRT; Load Ratio Control Transformer), includes four graph display areas capable of graphically displaying the time variation of electrical quantities. Each display area of display example 250 displays a time variation graph of electrical quantities in the same manner as display example 220 in FIG. 10. At this time, corresponding to the current setting value and the minimum load, the voltage acquisition device with identification number TVs4130 exceeds the range of the voltage specified value. Also, the voltage drop shows an increase up to 73 [V] at most. It can be seen that due to the influence of reverse power flow from distributed power sources such as biomass and power factor improvement capacitors connected to high-voltage consumers, the forward power factor reaches a maximum of 0.41 and the phase is greatly advanced.

[0088] The graph display screen in which display example 260 is shown in FIG. 15 includes four graph display areas capable of graphically displaying the time variation of electrical quantities when considering setting changes based on display example 250. Each display area of display example 260 displays a time variation graph of electrical quantities in the same manner as display example 240 in FIG. 12. Here, by changing to a combination of PC to LDC control (PC + LDC), which is the current voltage control method, and setting the resistance component of the setting impedance to 0.3 [Ω] and the reactance component to 0.1 [Ω], fluctuations due to the power factor are suppressed. The voltage control by PC lowers the voltage from 1 o'clock to 7 o'clock and from 19 o'clock to 21 o'clock. On the other hand, from 21 o'clock to 23 o'clock, the voltage is raised. As a result, it was confirmed that it is within the range of the voltage specified value. Therefore, it was confirmed that by supporting the consideration of voltage setting in a feedback manner, appropriate setting values can also be obtained in bus voltage setting.

[0089] An example of verifying the effects of the information processing apparatus 100 according to this embodiment will be described. In this verification, the conventional method in the setting study of the automatic voltage regulator was compared with the study time of the present invention by the feedback method.

[0090] The study time shown by Comparative Example 300 in FIG. 16 is shortened from the conventional 93 minutes to 51 minutes of the present invention. The conventional method has a small amount of measurement data acquisition, while the work of inputting measurement data into the study tool is large. On the other hand, the information processing apparatus 100 of the present invention has a large amount of measurement data acquisition, and the import of measurement data is speeded up, so that it is possible to shorten by 42 minutes compared with the conventional method.

[0091] Assume that in a certain power company, 185 automatic voltage regulators were inspected and replaced in one year. In this case, the study time for voltage setting is shortened by 130 hours, and when converted to the number of working days of 7.4 hours per day, there is an effect of reducing about 18 days.

[0092] As described above, by using the information processing apparatus 100 according to this embodiment, when considering the voltage setting of the voltage regulator, the work load can be reduced and the work time can be shortened. In addition, the accuracy of considering the voltage setting of the voltage regulator can be improved.

[0095] The display content of the consideration information can be arbitrarily changed corresponding to the specifications and programs of the information processing device 100. For example, corresponding to a combination of an arbitrary voltage adjustment device and a voltage acquisition device, it outputs a display capable of displaying determination information as to whether it is within the range of the voltage specified value, or a display capable of graphically displaying the time transition of electrical quantities. It may be the case that only one of these is executed.

[0096] The setting consideration support process in FIG. 3 is not limited to the case where all processes are executed without stopping from the timing when the execution is started, and some processes may be executed at different timings. For example, following the process of outputting a display capable of displaying the setting value consideration menu screen using the menu screen display information included in the various display information 135 stored in the storage unit 111, the process of acquiring, as input results, the designation information of the voltage adjustment device, the selection information of the voltage acquisition device, and other information that can be input on the setting value consideration menu screen may be executed at a plurality of timings while saving some of the input information until all the information is input. Also, after the input results on the setting value consideration menu screen are acquired, the display of the determination result corresponding to the current setting value and the graphical display of the electrical quantities may be made executable at the first timing, and the display of the determination result corresponding to the changed setting value and the graphical display of the electrical quantities may be made executable at a second timing different from the first timing.

[0097] The functions of the information processing apparatus 100 are not limited to being realized by a single device, and may be realized by a plurality of devices connected to be communicable with each other. The measurement data 200 is not limited to being entirely stored in the storage unit 111 of the information processing apparatus 100, and part or all of it may be stored in an external storage device via a network and be acquirable by communication processing using the communication unit 115.

[0098] The information processing apparatus 100 is not limited to executing a plurality of program modules included in the consideration support program 120 stored in the storage unit 111 by the processing unit 112. For example, a functional configuration realized by part or all of the programs may be realized by hardware.

[0099] The information processing apparatus 100 may be realized as a processing unit provided on the cloud as a computer using a processor. The voltage adjustment operation support process and the reclosing operation support process executed by the information processing apparatus 100 are not limited to being realized by the processing unit 112 executing a program stored in the storage unit 111, and may be realized as the program itself or as a recording medium on which the program is recorded.

[0100] A program executable by the information processing apparatus 100 may be stored and distributed in a non-temporary recording medium readable by a processing unit such as a flexible disk, a CD-ROM (Compact Disk Read-Only Memory), a DVD (Digital Versatile Disk), or an MO (Magneto-Optical Disk), and an apparatus capable of executing the processing of the above-described embodiment may be configured by installing the program in the processing unit.

Also, inventions equivalent to the invention described in the claims are included in the present invention.
