That is, the control unit 120 may calculate the holiday presence / absence criterion by calculating an average of the usage amounts of days with and without holidays during the past 30 days based on the diagnosis target date.

5A and 5C, when the date of diagnosis is [2014/11/01 Wednesday] as shown in FIG. 5C, the past 30 days are shown in FIG. 5A [2014/10] as shown in the figure and the Wednesday which is the diagnosis target date does not correspond to the holiday. Therefore, when the control unit 120 determines that the previous usage amount of the past 30 days from Monday to Friday The average of the daily use amount may be calculated to calculate the holiday existence standard.

In the case of such an example, the holiday presence criterion can be calculated as follows [reference 1].

[Reference 1] Example of calculation of holiday presence criteria

First weekday use (5 days): (30 + 40 + 50 + 300 + 30) = 450 [KWh]

Second weekday use (5 days): (30 + 40 + 50 + 100 + 20) = 240 [KWh]

Weekday usage on the 3rd week (5 days): (40 + 30 + 50 + 100 + 30) = 250 [KWh]

4th week Weekday use (5 days): (30 + 30 + 20 + 200 + 40) = 320 [KWh]

Fifth week Weekday usage (2 days): (40 + 20) = 60 [KWh]

Holiday standard: (450 + 240 + 250 + 320 + 60) / 22 = 60 [KWh]

That is, the holiday presence criterion for [2014/11/01] may be 60 [KWh].

The same day of the week is calculated as an average of the usage amounts of the same days in the past 30 days,

That is, the control unit 120 may calculate the average of the usage amounts of days having the same day of the week for the past 30 days based on the diagnosis target date, and calculate the holiday presence / absence standard.

5A and 5C, when the diagnosis target date is [2014/11/01 Wednesday] as shown in FIG. 5C, the past 30 days are shown in FIG. 5A Since the diagnosis target date is Wednesday, the control unit 120 calculates the average of the usage amounts of the days of the past 30 days of the past 30 days, and calculates the same day of the week .

In the case of such an example, the same day of the week criteria can be calculated as shown in [Reference 2] below.

[Reference 2] Example calculation based on the same day

Wednesday days (4 days): (50 + 50 + 50 + 20) = 170 [KWh]

Based on the same day: 170/4 = 42.5 [KWh]

That is, the same day of the week for [2014/11/01] could be 42.5 [KWh].

The outside temperature standard may be calculated as an average of the usage amounts of days having the same holidays and the same outside temperature during the past 30 days.

That is, the controller 120 may calculate the outside air temperature standard by calculating an average of the usage amounts of the days having the same holidays and the same outside air temperature during the past 30 days based on the diagnosis target date.

5A and 5C, when the diagnosis target date is [2014/11/01 Wednesday] as shown in FIG. 5C and the outside air temperature is 16 [DEG C] , The past 30 days is [2014/10] as shown in FIG. 5A, and the Wednesday as the diagnosis target date does not correspond to the holiday. Therefore, the control unit 120 determines that the past 30- And an average of the usage amounts of dates similar to 16 [° C], which is the outside temperature of the outside temperature [2014/11/01] during Monday to Friday excluding Saturday, to calculate the outside temperature standard.

In this case, the similarity criterion of the outside temperature can be set and inputted by the user of the central control device 100. [

For example, the similarity criterion can be set to the outside temperature standard of the diagnosis target date of ± 1 [° C].

In this case, the outside temperature criterion can be calculated as follows [reference 3].

[Reference 3] Calculation example based on outside temperature (rounded to the fourth decimal place)

(2 days): (15 + 14) = 29 [KWh]

Second day Weekday Outside temperature similar day usage (0 day): 0 [KWh]

Third day Weekday Outside temperature Similar day usage (1 day): 16 [KWh]

(4 days): (16 + 16 + 16 + 16) = 64 [KWh] for the fourth day of the weekday

Fifth week Weekday Outside temperature similar day usage (0 day): 0 [KWh]

Based on outside temperature: (29 + 16 + 64 + 60) / 7 = 24.143 [KWh]

That is, the outside temperature criterion for [2014/11/01] may be 24.143 [KWh].

The year-on-year standard may be calculated as an average of the usage amounts of the dates having the holidays of the previous year on the diagnosis target date basis.

That is, the control unit 120 may calculate an average of the usage amounts of the dates with and without the holiday of the previous year on the basis of the diagnosis target date, and calculate the year-on-year standard for the previous year.

5B and 5C, when the diagnosis target date is [2014/11/01 Wednesday] as shown in FIG. 5C, the year of the previous year is calculated as shown in FIG. 5B (2013/11), and the Wednesday, which is the diagnosis target date, does not correspond to the holiday. Therefore, when the control unit 120 determines that the weekday usage amount for the Monday to Friday except the Sunday and the Saturday The average of the previous year can be calculated.

In this case, the year-on-year basis of the previous year can be calculated as follows [reference 4].

[Reference 4] Example of calculation based on last year

First weekday use (5 days): (40 + 50 + 20 + 200 + 20) = 330 [KWh]

Second weekday use (5 days): (30 + 30 + 30 + 100 + 40) = 230 [KWh]

Weekday usage on the third week (5 days): (100 + 20 + 100 + 100 + 30) = 350 [KWh]

4th week Weekday usage (5 days): (40 + 30 + 40 + 200 + 20) = 330 [KWh]

Fifth week Weekday use (2 days): (30 + 40) = 70 [KWh]

Year-on-year basis: (330 + 230 + 350 + 330 + 70) / 22 = 59.545 [KWh]

That is, the year-on-year basis for [2014/11/01] could be 59.545 [KWh].

The normal range may be within the upper and lower limits of the past usage amount.

That is, the usage amount exceeding or exceeding the upper limit of the past usage amount may be excluded from the at least one abnormality diagnostic standard calculation basis.

The upper limit may be a value obtained by multiplying the average value of the upper 15 [%] usage amounts of the past usage amount by 1.15, and the lower limit may be a value obtained by multiplying the average value of the lower 15 [%] usage amounts of the past usage amount by 0.85.

An example of this will be described in detail with reference to FIG. 6 as follows

(100 + 80) / 2 = 90 [KWh] < 2 >

Upper limit: 90 x 1.15 = 91.15 [KWh]

(10 + 6) / 2 = 8 [KWh] Average amount of use # 3 (P3) and usage amount # 4 (P4)

Lower limit: 8 x 0.85 = 6.8 [KWh]

That is, the upper limit of the past usage amount may be 91.15 [KWh], and the lower limit may be 6.8 [KWh].

The control unit 120 may determine an abnormality degree of the energy usage amount depending on whether the energy usage amount exceeds a number of the at least one abnormality diagnosis criteria.

For example, as shown in FIG. 8, when the amount of energy used exceeds one of the at least one abnormality diagnosis criterion, it is determined that the abnormality degree of the energy usage is normal, If the amount of energy used is more than two out of the at least one abnormality diagnosis criterion, the abnormality degree of the energy use amount can be judged to be a low risk degree, and if the energy use amount exceeds three of the at least one abnormality diagnosis criterion, The abnormality degree of the energy usage can be judged to be a degree of intermediate risk and when the energy use amount exceeds four of the at least one abnormality diagnosis standard, If the energy usage exceeds all of the at least one anomaly criteria, The least amount of capacity can be determined that the degree of risk teukgo.

More specifically, for example, when the energy use amount is 59.9 [KWh], the holiday existence standard is 60 [KWh], the same day standard is 42.5 [KWh], the outside temperature standard is 24.143 [KWh] When the reference is 59.545 [KWh] and the prediction criterion is 41 [KWh], the energy usage exceeds the same day reference, the same year, and the prediction reference of the at least one abnormality diagnosis criterion, The control unit 120 may determine that the abnormality degree of the energy use amount is an intermediate risk degree.

8 is an example for explaining the determination criterion, and the criterion may be a form other than the example shown in FIG. 8 .
