When the predetermined time is, for example, 30 minutes, as shown in the figure, the daily limit has 48 power limit determination values.

  FIG. 7 is a diagram showing an example of the data structure of the time limit database 130 of this embodiment. This time limit database 130 is a database that stores the power supply time limit applied to unpaid customers. For example, the electric power contract number as customer identification information is used as a key, and the target date (the power supply limit is executed for the customer). Date) and power supply time limit (time for limiting power supply for the customer).

  FIG. 8 is a diagram showing an example of the data structure of the limit amount database 131 of this embodiment. The limit amount database 131 is a database that stores a power supply limit amount applied to unpaid customers. For example, key item groups such as “contract type”, “contract capacity”, “number of family members”, “special notes”, and the like are stored. As a key, it is an aggregate of records in which data such as the target date (the date on which the power supply restriction for the corresponding customer is executed) and the power supply restriction amount of the corresponding customer at regular time intervals are associated. The server 100 has a plurality of the limit database 131 that are divided into patterns by key items such as “contract type”, “contract capacity”, “number of family members”, “special notes”, and the like. Alternatively, the server 100 may have the limit amount database 131 for each customer. The power supply limit amount is the minimum amount of electric power necessary for daily life among customers having a predetermined attribute for each customer or an average value of electric energy measurement values of electric equipment having daily necessities.

--- Example of processing procedure 1 ---
Hereinafter, the actual procedure of the power supply management method in this embodiment will be described with reference to the drawings. Various operations corresponding to the power supply management method described below are realized by a program that is read out and executed in the RAM of the server 100 or the automatic meter reading device 200 constituting the system 10. And this program is comprised from the code | cord | chord for performing the various operation | movement demonstrated below.

  FIG. 9 is a diagram illustrating a processing flow example 1 of the power supply management method of the present embodiment. Here, first, each calculation process of the power limit determination value, the power supply limit time, and the power supply limit amount, which is a pre-process of the power supply limit process for unpaid customers, will be described. In this case, the control value calculation unit 110 of the server 100 identifies an unpaid customer whose electricity bill payment status data indicates unpaid charges in the payment management database 125 of the storage unit 101 (s100). In this specific process, the control value calculation unit 110 searches the payment management database 125 for customers whose “electricity charge overdue days”, which is the electricity bill payment status data, is “1” or more, and the found customers are unpaid. It will be identified as a customer. In the example of FIG. 2, the electric contract number “A0000001” can be specified as a customer whose number of days of electricity charge is “20”.

  Subsequently, the control value calculation unit 110 multiplies the length of the charge arrears period in the payment target date “July 2009” (“20 days” in the above example) by a predetermined value, and relates to the unpaid customer. A power limit determination value (= used in “July 2009”) is calculated, and the limit determination value database in the storage unit 101 is associated with the electric contract number “A0000001” as the customer identification information and the target date. It stores in 129 (s101). In calculating the power limit determination value, the control value calculation unit 110, for example, for the customer with the electric contract number “A0000001” in the payment management database 125, “the number of days of electricity charge arrears” = “20” and “final reminder” Data of “days until” = “30” is extracted. Further, data on average power usage matching the customer “A0000001” or the attribute of the customer is extracted from the average power usage database 128 shown in FIG. For example, in order to extract the average power consumption amount between customers matching the attribute of the customer “A0000001”, the control value calculation unit 110 reads “contract type” = “measured light B” in the payment management database 125. ”,“ Contract capacity ”=“ 60 ”,“ number of family members ”=“ 4 ”,“ special notes ”=“ 1 ”are extracted, and the average power usage data using these as key items is the average power It will be extracted from the usage database 128.

  Here, the control value calculation unit 110 is, for example, “average power consumption at a predetermined time × (1 / number of days until the final reminder) × 0.6” with respect to the “number of days when electricity charges are late” = “20”. Multiply the value to calculate the power limit judgment value. For example, if attention is paid to the average power usage “15” at the time “0:30” in the data of the average power usage matching the attribute of the customer “A0000001”, 15 × (1/30) × 0.6 = 0.3. Therefore, the control value calculation unit 110 multiplies the “number of days in which the electricity charges are late” = “20” by “0.3”, and sets the power limit determination value at the time “0:30” to “20 × 0.3”. "=" 6 "is calculated. Of course, other times are calculated in the same manner.

  Further, the control value calculation unit 110 calculates a power supply time limit applied to the unpaid customer by multiplying a predetermined value by the length of the charge delinquency period indicated by the electricity bill payment status data for the unpaid customer, It is stored in the time limit database 130 of the storage unit 101 in association with the electric contract number “A0000001” as customer identification information and the target date (s102). In calculating the power supply time limit, the control value calculation unit 110, for example, in the payment management database 125, for the customer with the electric contract number “A0000001”, “the number of days when the electric charge has been delayed” in “July 2009” = Data of “20” and “days until final reminder” = “30” are extracted. Here, the control value calculation unit 110 multiplies the “number of days of electricity charge arrears” = “20” by, for example, a value of “(1 / day until the last reminder) × 225” to set the power supply time limit. Calculate. For example, regarding “July 2009” of the customer “A0000001”, 20 × (1/30) × 225 = 150 (minutes) = 2 hours 30 minutes can be calculated as the power supply time limit. Of course, the same applies to other payment dates and customers.

  In addition, the control value calculation unit 110 calculates a power supply limit amount applied to the unpaid customer by multiplying a predetermined value by a reciprocal of the length of the charge delinquency period indicated by the electricity bill payment status data for the unpaid customer. Then, it is stored in the limit amount database 131 of the storage unit 101 in association with the electrical contract number, the target date, etc., which are customer identification information (s103). In calculating the power supply limit amount, the control value calculation unit 110, for example, for the customer with the electric contract number “A0000001” in the payment management database 125, “the number of days when the electric charge is late” = “20” and “final reminder” Data of “days until” = “30” is extracted. Further, data on average power usage matching the customer “A0000001” or the attribute of the customer is extracted from the average power usage database 128 shown in FIG. For example, in order to extract the average power consumption amount between customers matching the attribute of the customer “A0000001”, the control value calculation unit 110 reads “contract type” = “measured light B” in the payment management database 125. ”,“ Contract capacity ”=“ 60 ”,“ number of family members ”=“ 4 ”,“ special notes ”=“ 1 ”are extracted, and the average power usage data using these as key items is the average power It will be extracted from the usage database 128.

  Here, the control value calculation unit 110, for example, “average power consumption at a predetermined time × (1 / day until the last reminder) × 0.2” for “the number of days when the electricity bill is late” = “20”. Multiply the value to calculate the power supply limit. For example, if attention is paid to the average power usage “15” at time “0:30” in the data of the average power usage matching the attribute of the customer “A0000001”, 15 × (1/30) × 0.2. = 0.1. Therefore, the control value calculation unit 110 multiplies the “number of days in which the electricity charges are late” = “20” by “0.1” to set the power supply limit amount at the time “0:30” to “20 × 0.1. “=“ 2 ”is calculated. Of course, other times are calculated in the same manner.

  Thus, each calculation process of the power limit determination value, the power supply limit time, and the power supply limit amount is executed.

--- Processing procedure example 2 ---
FIG. 10 is a diagram illustrating a processing flow example 2 of the power supply management method of the present embodiment. Next, another calculation method for the power supply restriction amount will be described. In this case, the meter-reading unit 210 of the automatic meter-reading apparatus 200 communicates with each electrical device 50 in the customer facility via the network 16, and the measurement value of the wattmeter 51 provided in each electrical device 50 and the corresponding electrical device 50. The measurement data including the device identification information is acquired, and the customer identification information held in the storage unit 201 is attached to the measurement data and transmitted to the server 100 (s200).

  Meanwhile, the control value calculator 110 receives the measurement data from the automatic meter reading device 200 via the network 15 (s201). In addition, the control value calculation unit 110 includes, for example, the device identification information included in the measurement data during the predetermined period = time indicated by the record of each power supply limit amount in the limit amount database 131 in the necessary device database 126 in the storage unit 101. (S202). For example, the control value calculation unit 110 includes, among the measurement data received from the automatic meter reading device 200, the contract type is “meter-rate lamp B”, the contract capacity is “60”, the number of family members is “4”, and the special note is “1”. The device identification information is extracted from the measurement data at the time “0:30” relating to each customer having the customer attribute “and checked against the necessary device database 126. For example, when device identification information “EA000101” is included in certain measurement data, the control value calculation unit 110 checks the device identification information “EA000101” against the necessary device database 126 to obtain the corresponding measurement data. Can be identified as measurement data relating to electrical equipment having daily necessities.

  The control value calculation unit 110 identifies the measurement data related to the electrical equipment having the daily necessities necessary for the device identification information included in the essential equipment database 126 by the collation process, and determines the life from the measurement data. A measured value of the amount of power consumed by each electrical device as a necessary item is extracted (s203). In addition, the control value calculation unit 110 calculates the average value between the respective electric energy measurement values at the time “0:30” extracted in the step s203, so that the customer (= contract type is “subsidiary lamp B”). "A power supply limit amount applied to a customer having a customer attribute with a contract capacity of" 60 ", a family number of" 4 ", and a special note of" 1 ") is determined and stored in the limit amount database 131 (s204). ). Of course, other time and other customer attributes are similarly calculated.

--- Processing procedure example 3 ---
FIG. 11 is a diagram illustrating a processing flow example 3 of the power supply management method of the present embodiment. Next, processing when the power supply is limited in response to a customer who has not paid for electricity will be described. In this case, the meter-reading unit 210 of the automatic meter-reading apparatus 200 measures the amount of power used at the customer facility with a watt-hour meter or the like, the measured power consumption data, customer identification information held in the storage unit 201, and measurement Measurement data including the date and time is transmitted to the server 100 via the network 15 (s300).

  Meanwhile, the control instruction unit 111 of the server 100 receives the measurement data from the automatic meter reading device 200 via the network 15 (s301). Then, the control instruction unit 111 collates the electric contract number, which is the customer identification information included in the measurement data, with the payment management database 125 of the storage unit 101, and “electricity charge payment status data indicates unpaid charge” = electricity It is determined whether or not the customer is an unpaid customer whose charge arrears days is “1” or more (s302).

  If it is determined in step s302 that the customer is not an unpaid customer = the number of days in which the electricity charge is late (s302: paid), the control instruction unit 111 returns the process to step 300. On the other hand, if it is determined in step s302 that the customer is an unpaid customer (s302: unpaid), the control instruction unit 111 causes the unpaid customer's electric contract number and measurement date / time (server 100 is included in the measurement data). The power limit determination value at the corresponding time of the customer is acquired from the limit determination value database 129 using the measurement data reception date and time obtained by the clock function unit 208 provided as a computer as a key (s303). For example, the control instruction unit 111 uses the electric contract number “A0000001” of the unpaid customer included in the measurement data and the measurement date and time “2009/7/15: 0: 30” as a key from the limit determination value database 129. The power limit determination value “6” at the corresponding customer's corresponding time is acquired.

  The control instruction unit 111 compares the power consumption data included in the measurement data with the power limit determination value “6” of the customer “A0000001”, and the power consumption amount of the unpaid customer determines the power limit determination value. It is determined whether it exceeds (s304). For example, when the power consumption data included in the measurement data is “8”, compared with the power limit determination value “6” of the customer “A0000001”, the power consumption amount of the unpaid customer exceeds the power limit determination value. It will be determined. If it is determined in step s304 that the amount of power used by the unpaid customer does not exceed the power limit determination value (s304: OK), the control instruction unit 111 returns the process to step s300.

  On the other hand, if it is determined in step s304 that the amount of power used by the unpaid customer exceeds the power limit determination value (s304: NG), the control instruction unit 111 sets the time “0” of the customer “A0000001”. : 30 ″ is specified in the limit amount database 131 (s305). Alternatively, it is the power supply restriction amount related to the customer attribute, which is an attribute of the customer, the contract type is “meter-based lamp B”, the contract capacity is “60”, the number of family members is “4”, and the special note is “1”. The power supply limit amount related to the time “0:30” is specified in the limit amount database 131. In the example shown in FIG. 8, the power supply limit amount for the time “0:30” of the customer “A0000001” is “2”. In step s305, the control instructing unit 111 associates the power supply restriction flag “1” with the electric contract number “A0000001” as customer identification information of the corresponding customer, in the payment management database 125 of the storage unit 101. It is preferable to store it in the “supply restriction state” column.

  Therefore, the control instruction unit 111 gives an instruction to limit the amount of power supplied to the customer “A0000001” to the power supply limit amount “2”, and an automatic meter reading device corresponding to the electric contract number “A0000001” as the customer identification information It transmits to address 200 (s306). At this time, the control instruction unit 111 acquires the address on the network of the automatic meter reading device 200 in the “automatic meter reading device address” column in the payment management database 125 using the electric device “A0000001” as a key. Use.

  Note that, for example, in step s 305, the control instruction unit 111 may acquire information on the power supply time limit for the customer from the time limit database 130 using the electric contract number “A0000001” of the measurement data as a key. Good. For example, when the electrical contract number included in the measurement data is “A0000001”, the power supply limit time can be acquired as “2 hours 30 minutes” from the limit amount database 131.

  In this case, in step s306, the control instruction unit 111 issues an instruction to limit the supply power amount to the power supply limit amount for the power supply limit time from a predetermined time after a predetermined time from the reception time of the measurement data. The automatic meter reading device 200 may be transmitted to the address. For example, when the measurement data reception time is “0:35”, the control instruction unit 111 starts the power supply time limit “2 hours” from the time “10:00” after “25 minutes”, which is a predetermined time. An instruction to limit the power supply amount to the power supply limit amount “2” by “30 minutes” is transmitted to the address of the automatic meter reading device 200 corresponding to the electric contract number “A0000001”.

  On the other hand, the power control unit 211 of the automatic meter-reading apparatus 200 receives the instruction transmitted from the control instruction unit 111 of the server 100 via the network 15, and distributes the customer facility according to the instruction. The amount of power supplied in the board 300 is controlled (s307). In the above example, the power supply amount is “2”. As a situation where the power control unit 211 of the automatic meter reading device 200 controls the amount of power supplied in the distribution board 300, for example, a plurality of breakers having different rated values are installed in the distribution board 300 so as to be selectable. Can be assumed. A plurality of breakers are connected in parallel between the power transmission system side (electric power company side) and the power supply system side (power reception side) to the customer facility on the wiring of the distribution board 200, and the power control unit 211 When a breaker having a rated value equal to or less than the power supply amount “2” indicated by the instruction from the server 100 is selected, the predetermined switch that has received the selection sets the terminal of the corresponding breaker to the power transmission system and the supply system. Connect to. Of course, this is only an example, and any means that can control the amount of supplied power can be used.

--- Processing procedure example 4 ---
FIG. 12 is a diagram illustrating a processing flow example 4 of the power supply management method of the present embodiment. Next, for example, the processing after the power supply amount is limited to the power supply limit amount “2” from the time “10:00” for the power supply limit time “2 hours 30 minutes” will be described. In this case, a situation immediately after the power supply limit time “2 hours 30 minutes” has been assumed is assumed as an example.

  Here, the meter-reading unit 210 of the automatic meter-reading apparatus 200 measures the amount of power used at the customer facility with a watt-hour meter or the like, and measures the measured power consumption data, customer identification information stored in the storage unit 201, measurement date and time, It is assumed that measurement data including is transmitted to the server 100 via the network 15 (s400).

  On the other hand, the control instruction unit 111 of the server 100 receives the measurement data from the automatic meter reading device 200 via the network 15 after the power supply limit time “2 hours 30 minutes” has elapsed (s401). Then, the control instruction unit 111 collates the electric contract number “A0000001”, which is customer identification information included in the measurement data, with the payment management database 125 of the storage unit 101, and the corresponding customer is an unpaid customer, and the payment management database It is determined whether the power supply restriction flag “1” is set in the “supply restriction state” field of 125 (s402). In the case of the payment management database 125 illustrated in FIG. 2, the number of days of electricity charge arrears is “20”, and the power supply restriction flag “1” is set in the “supply restriction state” column. Therefore, it is determined that the customer “A0000001” is an unpaid customer and the power supply restriction flag is set.

  As described above, when the control instruction unit 111 determines that the customer is an unpaid customer and the power supply restriction flag is set as a result of the determination (s402: NG), the power consumption included in the measurement data The data is compared with the power limit judgment value of the customer (s403). Since the comparison processing between the power consumption data and the power limit determination value has already been described, the description is omitted here. On the other hand, if it is determined as a result of the determination that the customer is an unpaid customer but the power supply restriction flag is not set, or the customer is not an unpaid customer and the power supply restriction flag is not set (s402) : OK), the control instruction unit 111 returns the process to step s400.

  When it is determined in step s403 that the amount of power used by the unpaid customer exceeds the power limit determination value (s403: NG), the control instruction unit 111 starts from a predetermined time after a predetermined time from the reception time of the measurement data. An instruction to limit the power supply amount to the power supply limit amount for the power supply limit time is transmitted again to the address of the automatic meter reading device 200 corresponding to the customer identification information (s404). Since this instruction transmission processing has already been described, it is omitted here. On the other hand, as a result of the determination, when it is determined that the amount of power used by the unpaid customer does not exceed the power limit determination value (s403: OK), the control instruction unit 111 returns the process to step s400.

  On the other hand, the power control unit 211 of the automatic meter-reading apparatus 200 receives an instruction from the server 100 via the network 15 and controls the amount of power supplied to the distribution board 300 of the customer facility according to the instruction. (S405).

  As described above, according to the present embodiment, it is possible to effectively prompt payment to a customer who has not yet paid a fee by performing flexible power supply restriction according to the overdue period. Therefore, for the electric power company, it is possible to reduce the cost generated by continuing to supply electric power to customers who have not yet paid their fees. As a result, it is also possible to transfer the amount of power supplied to customers who have not yet paid to other customers, leading to the establishment of an efficient power supply system. On the other hand, for the customer, even if the delinquency is unavoidable, the minimum necessary power supply, which is judged according to the customer attributes and the electrical equipment used, is guaranteed. Cost reduction and conscientious response to unpaid customers from a humanitarian perspective.

  Accordingly, it is possible to flexibly limit the amount of electric power supplied according to customer attributes and the like, and to promote payment of electricity charges for customers who have not paid electricity charges.

  As mentioned above, although embodiment of this invention was described concretely based on the embodiment, it is not limited to this and can be variously changed in the range which does not deviate from the summary.
