The measurement device 3 includes a first measurement unit (measurement unit) 31 that measures the total power consumption at the customer 7, and a control unit 33 that controls the entire measurement device 3, separately from the power meter 2. . The first measurement unit 31 measures the total power consumption at the customer 7 using a current transformer that detects a current flowing in the main circuit on the input side of the main circuit breaker 51. That is, the first measuring unit 31 measures the total power usage amount in the distribution line 93 drawn from the power meter 2 to the load device 6 side. The control unit 33 outputs the measurement value of the first measurement unit 31 to the management device 1. In the example of FIG. 1, the measurement device 3 is provided separately from the distribution board 5, but the measurement device 3 may be provided integrally with the distribution board 5.

続いて、管理装置１について説明する。管理装置１は、負荷機器６の電力使用量を管理する。この管理装置１は、例えばＣＰＵ（Central Processing Unit：中央処理装置）およびメモリが搭載されたコンピュータ（マイクロコンピュータを含む）を主構成要素とし、取得部１１と、通信部１２と、補正部１３と、出力部１４とを備えている。
Subsequently, the management device 1 will be described. The management device 1 manages the power usage of the load device 6. The management device 1 includes, for example, a computer (including a microcomputer) on which a CPU (Central Processing Unit) and a memory are mounted as main components, and includes an acquisition unit 11, a communication unit 12, a correction unit 13, and the like. And an output unit 14.
取得部１１は、計測装置３から情報を受け取るためのインタフェース部を有しており、第１の計測部３１の計測値（需要家７での総電力使用量）を計測装置３から取得する。そして、取得部１１は、第１の計測部３１の計測値を、総電力使用量についての第１の値の初期値として、管理装置１の記憶部（図示せず）に書き込む。
The acquisition unit 11 has an interface unit for receiving information from the measurement device 3, and acquires the measurement value of the first measurement unit 31 (total power usage at the customer 7) from the measurement device 3. And the acquisition part 11 writes the measured value of the 1st measurement part 31 in the memory | storage part (not shown) of the management apparatus 1 as an initial value of the 1st value about total electric power consumption.
通信部１２は、電力メータ２と通信するインタフェース部を有しており、通信によって電力メータ２から検針情報を受信する。すなわち、通信部１２は、電力メータ２の計測値を電力メータ２から受け取る。そして、通信部１２は、電力メータ２から受け取った計測値を、総電力使用量についての第２の値の初期値として、管理装置１の記憶部（図示せず）に書き込む。
The communication unit 12 includes an interface unit that communicates with the power meter 2 and receives meter reading information from the power meter 2 through communication. That is, the communication unit 12 receives the measurement value of the power meter 2 from the power meter 2. And the communication part 12 writes the measured value received from the electric power meter 2 in the memory | storage part (not shown) of the management apparatus 1 as an initial value of the 2nd value about total power consumption.
補正部１３は、取得部１１が取得した計測値と通信部１２が受け取った計測値とを一致させるように補正する。言い換えると、補正部１３は、第１の値と第２の値とを一致させるように、第１の値および第２の値の少なくともいずれかを補正する。上述したように、第１の値は、総電力使用量についての値であり、第１の計測部３１の計測値を初期値とする。第２の値は、総電力使用量についての値であり、電力メータ２の計測値を初期値とする。すなわち、補正部１３は、需要家７での総電力使用量について第１の計測部３１の計測値と電力メータ２の計測値との差分がなくなるような補正を行う。例えば、第１の計測部３１の計測値と電力メータ２の計測値とが一致しない場合、補正部１３は、総電力使用量についての第１の値を第２の値の初期値（電力メータ２の計測値）に置き換える。これにより、電力メータ２が自己の計測値をそのまま表示する機能を有する場合に、管理装置１は、補正部１３で補正された値と、電力メータ２に表示される値とを一致させることができる。
The correction unit 13 corrects the measurement value acquired by the acquisition unit 11 and the measurement value received by the communication unit 12 to coincide with each other. In other words, the correction unit 13 corrects at least one of the first value and the second value so that the first value matches the second value. As described above, the first value is a value for the total power consumption, and the measurement value of the first measurement unit 31 is set as the initial value. The second value is a value for the total power consumption, and the measured value of the power meter 2 is the initial value. That is, the correction unit 13 performs correction so that the difference between the measurement value of the first measurement unit 31 and the measurement value of the power meter 2 is eliminated with respect to the total power consumption at the customer 7. For example, when the measurement value of the first measurement unit 31 and the measurement value of the power meter 2 do not match, the correction unit 13 sets the first value for the total power usage to the initial value of the second value (power meter 2). Thereby, when the power meter 2 has a function of displaying its own measurement value as it is, the management device 1 can match the value corrected by the correction unit 13 with the value displayed on the power meter 2. it can.
出力部１４は、補正部１３で補正された後の総電力使用量を表示装置４に表示させるために、上記総電力使用量を含む使用情報を表示装置４に出力する。すなわち、出力部１４は、補正部１３が補正した後の第１の値を含む使用情報を表示装置４に出力して表示装置４に表示させる。
The output unit 14 outputs usage information including the total power usage amount to the display device 4 in order to cause the display device 4 to display the total power usage amount corrected by the correction unit 13. That is, the output unit 14 outputs the usage information including the first value corrected by the correction unit 13 to the display device 4 and causes the display device 4 to display the usage information.
表示装置４は、例えばコントロールビューワであり、管理装置１の出力部１４から使用情報を取得し、この使用情報に含まれている総電力使用量（第１の値）を表示する。すなわち、表示装置４は、補正部１３で補正された後の総電力使用量を表示する。第１の計測部３１の計測値が電力メータ２の計測値に置き換えられた場合、表示装置４が表示する総電力使用量を、電力メータ２が表示する総電力使用量と一致させることができる。コントロールビューワは、需要家７に設置されており、需要家７の負荷機器６の状態などを表示する機器である。
The display device 4 is, for example, a control viewer, acquires usage information from the output unit 14 of the management device 1, and displays the total power usage (first value) included in the usage information. That is, the display device 4 displays the total power consumption after being corrected by the correction unit 13. When the measured value of the first measuring unit 31 is replaced with the measured value of the power meter 2, the total power usage displayed by the display device 4 can be matched with the total power usage displayed by the power meter 2. . The control viewer is installed in the consumer 7 and is a device that displays the state of the load device 6 of the consumer 7 and the like.
ところで、計測装置３は、分電盤５で分岐された分岐回路ごとに、上記分岐回路に接続された負荷機器６による電力使用量を計測する第２の計測部３２を備えている。複数の第２の計測部３２は、複数の分岐ブレーカ５２に一対一で対応付けられて設けられている。各第２の計測部３２は、対応する分岐ブレーカ５２の出力側の分岐回路に流れる電流を検出する電流トランスを用いて、上記分岐回路に接続されている負荷機器６による電力使用量を計測する。制御部３３は、各第２の計測部３２の計測値を管理装置１に出力する。
Incidentally, the measuring device 3 includes a second measuring unit 32 that measures the amount of power used by the load device 6 connected to the branch circuit for each branch circuit branched by the distribution board 5. The plurality of second measuring units 32 are provided in one-to-one correspondence with the plurality of branch breakers 52. Each second measuring unit 32 measures the amount of power used by the load device 6 connected to the branch circuit, using a current transformer that detects a current flowing in the branch circuit on the output side of the corresponding branch breaker 52. . The control unit 33 outputs the measurement value of each second measurement unit 32 to the management device 1.
管理装置１において、取得部１１は、複数の第２の計測部３２の計測値（各分岐回路の電力使用量）を計測装置３から取得する。そして、取得部１１は、分岐回路ごとに、第２の計測部３２の計測値を、分岐回路の電力使用量についての第３の値の初期値として管理装置１の記憶部（図示せず）に書き込む。
In the management device 1, the acquisition unit 11 acquires the measurement values (the power usage amount of each branch circuit) of the plurality of second measurement units 32 from the measurement device 3. And the acquisition part 11 is a memory | storage part (not shown) of the management apparatus 1 by making the measured value of the 2nd measurement part 32 into the initial value of the 3rd value about the electric power consumption of a branch circuit for every branch circuit. Write to.
補正部１３は、需要家７での総電力使用量に対する補正量に合わせて、取得部１１が取得した各分岐回路の電力使用量を補正する。すなわち、補正部１３は、分岐回路ごとに、需要家７での総電力使用量についての第１の値および第２の値に関する補正量に合わせて、分岐回路の電力使用量についての第３の値を補正する。第１の値の初期値（第１の計測部３１の計測値）に対する第２の値の初期値（電力メータ２の計測値）の割合を補正量とすると、補正部１３は、分岐回路ごとに、第３の値を、当該第３の値の初期値と当該補正量との積に補正する。総電力使用量について電力メータ２の計測値Ｐ２が第１の計測部３１の計測値Ｐ１に対してＡ％大きい場合（Ｐ２＝Ｐ１×（１００＋Ａ）／１００の場合）、補正部１３は、各分岐回路の電力使用量をＡ％だけ大きくする。すなわち、補正部１３は、分岐回路ごとに、第３の値を初期値からＡ％だけ大きくする。例えば、総電力使用量について電力メータ２の計測値Ｐ２が第１の計測部３１の計測値Ｐ１に対して４％大きい場合（Ｐ１＝Ｐ２×１．０４の場合）、補正部１３は、各分岐回路の電力使用量を４％だけ大きくする。すなわち、補正部１３は、分岐回路ごとに、第３の値を初期値から４％だけ大きくする。
The correction unit 13 corrects the power usage amount of each branch circuit acquired by the acquisition unit 11 in accordance with the correction amount with respect to the total power usage amount at the customer 7. That is, for each branch circuit, the correction unit 13 adjusts the third power consumption amount of the branch circuit in accordance with the correction amount related to the first value and the second value for the total power usage amount at the customer 7. Correct the value. When the ratio of the initial value of the second value (measured value of the power meter 2) to the initial value of the first value (measured value of the first measuring unit 31) is a correction amount, the correcting unit 13 In addition, the third value is corrected to the product of the initial value of the third value and the correction amount. When the measured value P2 of the power meter 2 is A% larger than the measured value P1 of the first measuring unit 31 with respect to the total power consumption (in the case of P2 = P1 × (100 + A) / 100), the correcting unit 13 Increase the power consumption of the branch circuit by A%. That is, the correction unit 13 increases the third value by A% from the initial value for each branch circuit. For example, when the measurement value P2 of the power meter 2 is 4% larger than the measurement value P1 of the first measurement unit 31 with respect to the total power consumption (in the case of P1 = P2 × 1.04), the correction unit 13 Increase the power consumption of the branch circuit by 4%. That is, the correction unit 13 increases the third value by 4% from the initial value for each branch circuit.
出力部１４は、補正部１３で補正された後の各分岐回路の電力使用量を表示装置４に表示させるように、各分岐回路の電力使用量を含む使用情報を表示装置４に出力する。すなわち、出力部１４は、分岐回路ごとに、補正部１３が補正した後の第３の値を含む使用情報を表示装置４に出力して表示装置４に表示させる。
The output unit 14 outputs usage information including the power usage amount of each branch circuit to the display device 4 so that the power usage amount of each branch circuit after being corrected by the correction unit 13 is displayed on the display device 4. That is, the output unit 14 outputs the usage information including the third value after correction by the correction unit 13 to the display device 4 for each branch circuit and causes the display device 4 to display the usage information.
また、管理装置１は、総電力使用量について取得部１１が取得した計測値と通信部１２が受け取った計測値との差の絶対値がしきい値よりも大きい場合に異常と判断する異常判断部１５をさらに備えている。すなわち、総電力使用量について第１の計測部３１の計測値と電力メータ２の計測値との差の絶対値がしきい値よりも大きい場合、異常判断部１５は、異常が発生していると判断する。しきい値は、電力メータ２と計測装置３との計測ばらつきよりも大きな値に予め決められている。異常判断部１５が判断する異常としては、計測装置３の異常、電力メータ２の異常、管理装置１の異常などがある。出力部１４は、異常判断部１５の判断結果を表示装置４に出力して表示装置４に表示させる。
In addition, the management device 1 determines an abnormality when the absolute value of the difference between the measurement value acquired by the acquisition unit 11 and the measurement value received by the communication unit 12 with respect to the total power usage is greater than the threshold value. A part 15 is further provided. That is, when the absolute value of the difference between the measurement value of the first measurement unit 31 and the measurement value of the power meter 2 is greater than the threshold value with respect to the total power usage, the abnormality determination unit 15 has an abnormality. Judge. The threshold value is determined in advance to a value larger than the measurement variation between the power meter 2 and the measuring device 3. Examples of the abnormality determined by the abnormality determination unit 15 include an abnormality of the measuring device 3, an abnormality of the power meter 2, and an abnormality of the management device 1. The output unit 14 outputs the determination result of the abnormality determination unit 15 to the display device 4 and causes the display device 4 to display the determination result.
次に、本実施形態に係る管理システムの動作について説明する。まず、電力メータ２が需要家７での総電力使用量を計測し、管理装置１が電力メータ２の計測値（総電力使用量）を通信によって受け取る。上記とは別に、管理装置１は第１の計測部３１の計測値（総電力使用量）と複数の第２の計測部３２の計測値（各分岐回路の使用電力量）とを計測装置３から取得する。その後、管理装置１は、総電力使用量について第１の計測部３１の計測値と電力メータ２の計測値とを一致させるように補正する。また、管理装置１は、総電力使用量の補正量に合わせて、各分岐回路の電力使用量についての計測値を補正する。その後、管理装置１は、補正後の電力使用量（総電力使用量、各分岐回路の電力使用量）を含む使用情報を表示装置４に出力する。表示装置４は、管理装置１から使用情報を取得し、この使用情報に含まれている電力使用量を表示する。
Next, the operation of the management system according to this embodiment will be described. First, the power meter 2 measures the total power usage at the customer 7, and the management device 1 receives the measured value (total power usage) of the power meter 2 by communication. Apart from the above, the management device 1 uses the measurement value of the first measurement unit 31 (total power consumption) and the measurement value of the plurality of second measurement units 32 (power consumption of each branch circuit) as the measurement device 3. Get from. Thereafter, the management device 1 corrects the total power consumption so that the measurement value of the first measurement unit 31 matches the measurement value of the power meter 2. Moreover, the management apparatus 1 correct | amends the measured value about the power usage of each branch circuit according to the correction amount of total power usage. Thereafter, the management device 1 outputs usage information including the corrected power usage (total power usage, power usage of each branch circuit) to the display device 4. The display device 4 acquires usage information from the management device 1 and displays the power usage amount included in the usage information.
以上説明した本実施形態によれば、管理装置１は、第１の計測部３１で計測された総電力使用量と電力メータ２で計測された総電力使用量とを一致させるように補正し、補正後の総電力使用量を出力する。すなわち、管理装置１は、需要家７での総電力使用量について、第１の値と第２の値とを一致させるように第１の値および第２の値の少なくともいずれかを補正する。そして、管理装置１は、補正した後の第１の値を出力する。これにより、本実施形態の管理装置１は、需要家７での総電力使用量について異なる値が存在する場合に比べて、ユーザの混乱を低減させることができる。すなわち、本実施形態の管理装置１は、第１の計測部３１の計測値（第１の値の初期値）と電力メータ２の計測値（第２の値の初期値）とが異なっていても、両方の計測値をそのまま出力する場合に比べて、ユーザの混乱を低減させることができる。
According to the present embodiment described above, the management device 1 corrects the total power usage measured by the first measurement unit 31 and the total power usage measured by the power meter 2 so as to match, Output the total power consumption after correction. That is, the management device 1 corrects at least one of the first value and the second value so that the first value and the second value are matched with each other with respect to the total power usage amount at the customer 7. Then, the management apparatus 1 outputs the corrected first value. Thereby, the management apparatus 1 of this embodiment can reduce a user's confusion compared with the case where a different value exists about the total electric power consumption in the consumer 7. FIG. That is, in the management device 1 of the present embodiment, the measurement value of the first measurement unit 31 (initial value of the first value) and the measurement value of the power meter 2 (initial value of the second value) are different. However, the confusion of the user can be reduced as compared with the case where both measurement values are output as they are.
また、本実施形態によれば、管理装置１は、補正部１３において、総電力使用量に対する補正量に合わせて、各分岐回路の電力使用量を補正する。すなわち、本実施形態の管理装置１は、分岐回路ごとに、第２の計測部３２の計測値を、分岐回路の電力使用量についての第３の値の初期値とし、総電力使用量についての第１の値および第２の値に関する補正量に合わせて、第３の値を補正する。これにより、本実施形態の管理装置１は、各分岐回路の電力使用量を総電力使用量に整合させることができるので、総電力使用量と各分岐回路の電力使用量との間で矛盾が生じない。
Further, according to the present embodiment, the management device 1 corrects the power usage amount of each branch circuit in the correction unit 13 in accordance with the correction amount with respect to the total power usage amount. That is, the management device 1 according to the present embodiment sets, for each branch circuit, the measurement value of the second measurement unit 32 as the initial value of the third value for the power usage amount of the branch circuit, and the total power usage amount. The third value is corrected in accordance with the correction amount related to the first value and the second value. Thereby, since the management apparatus 1 of this embodiment can match the power usage of each branch circuit with the total power usage, there is a contradiction between the total power usage and the power usage of each branch circuit. Does not occur.
さらに、本実施形態によれば、管理装置１は、補正部１３で補正された後の値（総電力使用量、各分岐回路の電力使用量）を表示装置４に表示させる。これにより、本実施形態の管理装置１は、未補正の値を表示装置４に表示させる場合に比べて、表示内容を見たユーザの混乱を低減させることができる。
Furthermore, according to the present embodiment, the management device 1 causes the display device 4 to display values (total power usage, power usage of each branch circuit) after correction by the correction unit 13. Thereby, the management apparatus 1 of this embodiment can reduce the confusion of the user who looked at the display content compared with the case where the display apparatus 4 displays an uncorrected value.
また、本実施形態の管理装置１において、異常判断部１５は、第１の計測部３１の計測値（第１の値の初期値）と電力メータ２の計測値（第２の値の初期値）との差の絶対値がしきい値よりも大きい場合に異常と判断する。これにより、本実施形態の管理装置１は、電力メータ２および第１の計測部３１の計測精度のばらつき以上の値にしきい値を予め設定することによって、本来同じ値でなければならない２つの計測値（総電力使用量）が上記ばらつき以上に異なる場合、例えば電力メータ２や第１の計測部３１（計測装置３）などが異常であることを簡単かつ早期に検出することができる。
Further, in the management device 1 of the present embodiment, the abnormality determination unit 15 includes the measurement value (initial value of the first value) of the first measurement unit 31 and the measurement value (initial value of the second value) of the power meter 2. If the absolute value of the difference from () is larger than the threshold value, it is determined as abnormal. Thereby, the management apparatus 1 of this embodiment sets two threshold values which should be originally the same value by presetting a threshold value to a value equal to or greater than the variation in measurement accuracy of the power meter 2 and the first measurement unit 31. When the value (total power consumption) differs by more than the above variation, it can be easily and early detected that the power meter 2 or the first measurement unit 31 (measurement device 3) is abnormal, for example.
なお、電力メータ２の計測値を変更することが許容されるならば、第１の計測部３１の計測値と電力メータ２の計測値とを一致させる補正の一例として、補正部１３は、電力メータ２の計測値を第１の計測部３１の計測値に置き換えてもよい。すなわち、補正部１３は、第２の値を第１の値に置き換えることによって、第１の値と第２の値とを一致させてもよい。言い換えると、補正部１３は、管理装置１の記憶部（図示せず）に記憶されている第２の値を、当該記憶部に記憶されている第１の値の初期値に変更してもよい。また、上記補正の他の例として、補正部１３は、第１の計測部３１の計測値と電力メータ２の計測値との平均値を新たな総電力使用量としてもよい。すなわち、補正部１３は、第１の値および第２の値を、第１の値の初期値と第２の値の初期値との平均値に置き換えることによって、第１の値と第２の値とを一致させてもよい。言い換えると、補正部１３は、管理装置１の記憶部（図示せず）に記憶されている第１の値および第２の値を当該平均値に変更してもよい。

The value may be matched. In other words, the correction unit 13 may change the first value and the second value stored in the storage unit (not shown) of the management device 1 to the average value.
