【発明の属する技術分野】
本発明はバイパス線による盗電を検知でき、盗電を防止するのに好適な電力売買の方法及び電力売買システムに関する。
【０００２】
【従来の技術】
バイパスによる盗電が行われ、盗電される電力量が大きな割合を占めると、電力会社の電力コマーシャル損失を著しく低下させることになる。バイパスによる盗電は、単純な手法であるにも係らず、発見する適用な手段がないため防止することは困難な状況にある。
【０００３】
従来の技術としては、
【特許文献１】に記載のように、電力量計本体，カバー，ベースで電力量計量素子を収納する筐体を形成し、電力量計量素子で計量される電力量を視認できるように数値表示する電力量計において、電力量計の封印が破壊されてあるいは偽装再封印されて盗電などの不正行為を防止するために、封印ネジの頭部の位置変化を検知する電力量計がある。
【０００４】
又、
【特許文献２】に記載のように、電力需給計器の一部にバイパス線検出回路を設け、このバイパス線検出回路は、電流変圧器，テスト電流作動増幅調整回路，テスト電流調整回路，テスト電流増幅回路からの信号によって、電流検出線を流れるテスト電流を検出し、被注入テスト電流と被測定テスト電流とに僅かでも差異があれば、信号がメインコントローラに送られ、バイパス線が存在することを示すようにした改良型電力需給計器及び方法がある。

【０００６】
【発明が解決しようとする課題】
【特許文献１】に記載の従来の技術は、電力量計の封印を破壊するあるいは偽装再封印による盗電等の不正行為を防止するものであり、電力量計とは別の場所を導体によりバイパスして行う盗電（以下、便宜上バイパス盗電という）を防止することができないものであった。
【０００７】
又、
【特許文献２】に記載の従来技術は、電力量計に内蔵した電源からのテスト電流を内蔵の電流変圧器で検出してバイパス線の有無を判定するので、測定しようとする電力需要家を停電させた状態でないと検出できないものであった。
【０００８】
本発明の目的は、電力需要家を停電させないでもバイパス線による盗電を検出できる電力売買の方法及び電力売買システムを提供することにある。
【０００９】
本発明の他の目的は、電力コマーシャル損失を低下させ、電力料金の回収率を向上させる電力売買の方法及び電力売買システムを提供することにある。
【００１０】
【課題を解決するための手段】
上記目的を達成するために、本発明の電力売買システム及び方法は、電力の売買契約において、電力量計を設置することを許諾した電力需要家に対しては、電力料金を割引するインセンティブを与える。電力を供給するための配電線の電力需要家と接続する分岐点より上流側と下流側の配電線の各点，分岐点より分岐した電力需要家の受電点の３点の電流値又は電力量を計測する電流検出装置，電力量計を設け、電流検出装置，電力量計で測定された電流値又は電力量を計算機に送信して記憶装置に記憶し、３点の電流値又は電力量に基づいて盗電が行われているか否かを判定するものである。
【００１１】
又、電力需要家を識別して登録している電力需要家情報から電力量計を設置している電力需要家、又は盗電の判別結果を電力需要家と紐付けして記録した盗電判定情報から盗電を行っていないと判定された電力需要家に対して盗電についての処置方法を格納した盗電対応情報を参照して電力需要家毎の電力使用量を記録している検針データ情報から電力料金を割引するインセンティブを与えて電力料金を自動計算する、あるいは盗電の判別結果を電力需要家と紐付けして記録した盗電判定情報から盗電を行っていると判定された電力需要家に対して盗電についての処置方法を格納した盗電対応情報及び電力需要家を識別して登録している電力需要家情報を参照してペナルティを与えて盗電を防止するものである。
【００１２】
これにより、バイパスによる盗電も含めて盗電を効果的に防止でき、電力コマーシャル損失が低減できる。
【００１３】
【発明の実施の形態】
本発明の一実施例を図１から図５により説明する。図１は、本実施例のシステム構成図である。変電所１には、配電線２が接続され、配電線２の分岐点３から電力量計８を介して配電線１６により電力需要家９に電力を供給する例を示している。
【００１４】
本実施例では、変電所１と分岐点３との間に電流検出装置４を取付けるための取付部１４を設け、電流検出装置４を介してデータ送信装置５が設けられている。配電線２の分岐点３より変電所１から離れた位置には、電流検出装置６を取付けるための取付部１５を設け、電流検出装置６を介してデータ送信装置７が設けられている。このように、配電線２の分岐点３の上流側および下流側に電流検出装置４，６をそれぞれ設けている。
【００１５】
電力需要家９と配電線２とは、分岐点３から電力量計８を介して接続され、電力量計８にはデータ送信装置１０が接続されている。データ送信装置５，７，
１０は、無線通信などの通信装置を介してデータ受信装置１１に測定データを送信する。
【００１６】
電流検出装置４，６，電力量計８で測定される電流値は、検出した電流検出装置又は電力量計を識別するための識別情報及び測定された時刻情報と紐付けされ、データ送信装置５，７，１０から送信される。データ送信装置５，７，１０から送信された測定データは、データ受信装置１１で受信して計算機１２へ送信される。測定データを受信した計算機１２は、後述するように盗電が行われているか否かを判定するための計算を行い、計算結果を計算機１３に送信する。
【００１７】
計算機１２には、図２に示すように、変電所の位置を示す位置情報３１，変電所と配電線の接続関係を示す接続情報３２，電力需要家と配電線，分岐点の関係を示す需要家情報３３，電流検出装置あるいは電力量計の設置位置を示す設置位置情報３４を配電データベース３０として記憶装置に記憶している。又、データ送信装置５，７，１０から送信される測定データは、電流検出装置又は電力量計の識別情報及び時刻情報と紐付けされた履歴情報として履歴情報データベース
３５に記憶される。
【００１８】
盗電が行われているか否かを監視している計算機１２は、測定データを蓄積する一方、蓄積された測定データを使用して盗電が行われているか否かをチェックする計算を行う。電力需要家９が指定されると、配電データベース３０を検索して需要家情報から電力需要家９に接続される分岐点３を検索し、設置位置情報を参照して分岐点３の上流側及び下流側に設置される電流検出装置４，６を検索する。又、分岐点３から電力需要家９の間に設置された電力量計８を検索する。このようにして、分岐点３の周りに配置された電流検出装置４，６，電力量計８が特定されると、図３に示す盗電検出方法により盗電の有無を判定する。
【００１９】
図３に示すように、電力は変電所１から配電線２により、分岐点３を経て電力需要家９に供給される。バイパスによる盗電が行われている場合には、電力需要家９の電力使用量を測定する電力量計８の前後をバイパス線２０で接続して電力量計８がバイパスされている。上述したように、測定点である配電線２に設置された電流検出装置４を流れる電流値ＩＵ ，電流検出装置６を流れる電流値ＩＤ ，電力量計８を流れる電流値ＩＷＨＭ が測定され、時刻情報を紐付けして記録されている。測定した時刻情報から換算された同時刻の各電流検出装置，電力量計の電流値を抽出するか、又は設定した期間における測定値の平均値を用いて、数１が成立するかどうかを判定する。数１が成立した時は、バイパス線２０を設置して盗電が行われている可能性がある。
【００２０】
【数１】

Figure 2004340767
ここで、数１は、分岐点の上流側検出点の電流値ＩＵ から分岐点の下流側検出点の電流値ＩＤ と、電流検出装置４と電流検出装置６と電力量計８間で発生するモレ電流値Ｌを引いた値が、電力量計８を流れる電流値ＩＷＨＭ よりかなり大きいことを示しており、バイパス線２０を電流が流れていることを意味している。この判定は閾値を設定してこの閾値より大きいか否かで行う。以上では、電流値で盗電を説明する場合を説明したが、電力量で同様な計算を行い、盗電を判定することもできる。
【００２１】
このようにして、計算機１２により盗電が行われているか否か監視しているが、これを元に盗電を防止する電力売買方法を行うこともできる。
【００２２】
図２に示すように、計算機１３は、電力需要家を識別して登録している電力需要家情報４１，電力需要家毎の電力使用量を記録している検針データ情報４２，計算機１２で計算された盗電の判別結果を電力需要家と紐付けして記録した盗電判定情報４３，盗電が行われていない場合の割引インセンティブ，盗電が行われている場合のペナルティー，追加料金，電力供給についての処置方法を格納した盗電対応情報４４をデータベースとして備えている。
【００２３】
図４は、本実施例の電力売買方法におけるフローチャートを示す図である。ステップ５０で、上述したように電力使用量の検針及び盗電を検知するためのデータの測定を毎月，毎週，毎日、あるいは決められた時刻に定期的に実施する。ステップ５０で実施したデータの測定結果を蓄積し、ステップ５１で計算機１２により盗電有無の判定を行う。その判定結果で盗電が行われていないと判断されれば、計算機１２の結果は計算機１３に送信され、ステップ５２で、計算機１３により割引を考慮した電力料金計算を行い、その電力料金計算結果に基づいて、ステップ５３で課金，徴収が実施される。盗電有無の判定は定期的に繰り返され、盗電判定情報４３を参照して、盗電が行われていないと判定されれば、盗電対応情報４４を参照して割引かれた電力料金で電力の売買が行われる。
【００２４】
一方、ステップ５１の盗電有無の判定結果が盗電が行われているとの判定の場合は、ステップ５４で、電力会社は盗電の有無の現場査察，調査を行う。その現場査察，調査した結果をもとに、ステップ５５で盗電が確定かどうかの判定を行う。その判定の結果、ステップ５１の盗電が行われているとの判定結果が誤りであると確認されれば、ステップ５１の盗電有無の判定を盗電が行われていないに訂正したルーチンに戻る。
【００２５】
ステップ５５で盗電が行われていることが確認された場合は、ステップ５６で電力会社は電力需要家に対しペナルティーを課す。電力需要家へのペナルティーは、追加料金の請求，電力供給の制限又は停止，電力料金の割引インセンティブの剥奪などが考えられ、盗電対応情報４４を参照して決められる。
【００２６】
図５は、以上説明した電力会社と電力需要家のやり取りを纏めて示した図である。
【００２７】
図５に示すように、通常、電力会社１００は、電力需要家１０１に対し電力供給１０２を行う。電力会社１００は、電力供給１０２を行う前に、電力需要家１０１に許諾を得て、盗電行為を監視するための検出装置である電力量計８の設置１０３を行う。電力会社１００は、検出装置の設置を許諾した電力需要家１０１に対して、電力料金の割引インセンティブの付与１０４を行う。電力会社１００は、電力使用量検針１０５を行い、計算機１３により電力需要家１０１に電力使用量検針１０５により検針された電力使用量に電力料金の割引インセンティブを考慮した割引電力料金を計算して割引電力料金請求１０６を行う。電力需要家１０１は割引電力料金請求１０６を受け取ると自動振込み等により電力会社１００に電力料金支払１０７を行う。
【００２８】
本実施例の電力売買方法によれば、電力会社１００及び電力需要家１０１の双方に次のようなメリットが発生する。
【００２９】
電力需要家１０１のメリットは、合法的な方法で電力供給を受けていれば、割引電力料金を支払えばよいので、電力コストを削減できる。
【００３０】
特に電力会社１００側で盗電有無の判定を行っているので、アジア地域で最近問題となっている盗電行為の正確な判定も行われるので、刑事責任，民事責任を含む社会的制裁に対するリスクを負う必要がなくなる。
【００３１】
一方、電力会社２００のメリットは、盗電が低減されることにより電力料金の回収率が向上し、電力コマーシャル損失の低減を実現できる。ここで、電力コマーシャル損失とは、変圧器，遮断機，送配電線などの送配電設備の電気抵抗により発生する電力テクニカル損失と、それ以外の原因で発生する電力損失があり、それ以外の原因の１つには盗電がある。特に盗電は、電力料金が回収されない問題を発生させる。
【００３２】
電力会社１００は、ある設定期間に計測した結果、数２が成立する場合には経済的メリットを受けることができる。
【００３３】
【数２】
Figure 2004340767
ここで、数２では説明を簡単にするため、設定期間を一年間としており、Ｆｄは、本実施例を適用して割引した電力料金請求で徴収した一年間の累積額、Ｆａは、本実施例を適用しないで徴収することができる一年間の累積額、Ｉは、本実施例を適用して盗電を監視する装置設置のための一年間の投資累積額、Ｃは本実施例を適用したシステムの運用のためのランニングコストの一年間の累積額である。
【００３４】
本実施例によれば、電力量計の不正改造および不正使用による盗電の他、単純な手法であるにも係らず、防止困難であったバイパスによる盗電を確実に検出することができ、盗電対策により電力コマーシャル損失を低下させ、電力料金の回収率を向上させることができる。
【００３５】
又、契約方法や制度を活用して、盗電を行っていない電力需要家に対しては電力料金を割引等有利な電力売買を行い、盗電を行っている電力需要家に対してはペナルティー，追加料金，電力供給についての処置を設けることにより、電力需要家の盗電防止を図ることができ、有効な総合的盗電防止対策を提供できる。
【００３６】
【発明の効果】
本発明によれば、電力需要家への給電を停止して停電にしなくても電力需要家の盗電を確実に検出することができる。その結果、電力会社の電力コマーシャル損失を低減させることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a power trading method and a power trading system suitable for detecting power theft by a bypass line and preventing power theft.
[0002]
[Prior art]
If power is stolen by bypass and power stolen occupies a large proportion, the power commercial loss of the power company will be significantly reduced. Although the theft by the bypass is a simple method, it is difficult to prevent it because there is no applicable means to discover.
[0003]
As a conventional technology,
As described in Patent Document 1, a housing for accommodating an electric energy meter is formed by a watt hour meter main body, a cover, and a base, and numerical values are displayed so that the electric energy measured by the electric energy meter can be visually recognized. Among the watt-hour meters that can be used, there is a watt-hour meter that detects a change in the position of the head of a sealing screw in order to prevent a fraudulent act such as a power theft by breaking the seal of the watt-hour meter or disguising and resealing.
[0004]
or,
As described in Patent Document 2, a bypass line detection circuit is provided in a part of a power supply and demand meter, and the bypass line detection circuit includes a current transformer, a test current operation amplification adjustment circuit, a test current adjustment circuit, and a test current. The test current flowing through the current detection line is detected by the signal from the amplifier circuit. If there is any difference between the test current to be injected and the test current to be measured, a signal is sent to the main controller and the bypass line exists. There is an improved power supply and demand meter and method as shown below.
[0005]
[Patent Document 1]
JP-A-2002-257682 [Patent Document 2]
JP 2000-249730 A
[Problems to be solved by the invention]
The conventional technique described in Patent Document 1 is intended to prevent fraudulent acts such as power theft by breaking the seal of the watt-hour meter or re-sealing by disguising and re-sealing, and bypass a place different from the watt-hour meter by a conductor. Power theft (hereinafter, for convenience, referred to as bypass theft) cannot be prevented.
[0007]
or,
In the prior art described in Patent Document 2, the presence or absence of a bypass line is determined by detecting a test current from a power supply built in a watt hour meter with a built-in current transformer. It could not be detected without a power outage.
[0008]
An object of the present invention is to provide a power trading method and a power trading system that can detect power theft by a bypass line without stopping a power consumer.
[0009]
It is another object of the present invention to provide a power trading method and a power trading system that reduce a power commercial loss and improve a recovery rate of a power rate.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the power trading system and method of the present invention provide an incentive to discount a power rate to a power customer who has licensed a watt hour meter in a power sales contract. . The current value or the amount of power at three points: each point of the distribution line upstream and downstream from the branch point connecting the power consumer to the distribution line for supplying power, and the receiving point of the power customer branched from the branch point A current detection device and a watt-hour meter that measure the current are sent to the computer, and the current value or the power amount measured by the current detection device and the watt-hour meter is transmitted to a computer and stored in a storage device. It is to determine whether or not the power theft has been performed based on this.
[0011]
Also, from the power customer information that identifies and registers the power customer, the power customer who has installed the watt-hour meter, or the power theft determination information recorded in association with the power customer in the determination result of power theft. For power consumers determined not to have performed power theft, refer to the theft-compliant information that stores the treatment method for theft and refer to the power-storage information to record the power usage for each power consumer. The power rate is automatically calculated by giving an incentive to discount, or power theft is determined for power consumers who are determined to be performing power theft based on the power theft determination information recorded in association with the power consumers. The penalty is given by referring to the power-storage correspondence information storing the above-mentioned treatment method and the power consumer information that identifies and registers the power consumer, thereby preventing power theft.
[0012]
As a result, power theft including power theft by the bypass can be effectively prevented, and the power commercial loss can be reduced.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a system configuration diagram of the present embodiment. An example is shown in which a distribution line 2 is connected to a substation 1, and power is supplied from a branch point 3 of the distribution line 2 to a power consumer 9 via a distribution meter 16 via a wattmeter 8.
[0014]
In the present embodiment, a mounting portion 14 for mounting the current detection device 4 is provided between the substation 1 and the branch point 3, and a data transmission device 5 is provided via the current detection device 4. At a position away from the substation 1 from the branch point 3 of the distribution line 2, a mounting portion 15 for mounting the current detection device 6 is provided, and a data transmission device 7 is provided via the current detection device 6. As described above, the current detection devices 4 and 6 are provided on the upstream side and the downstream side of the branch point 3 of the distribution line 2, respectively.
[0015]
The power consumer 9 and the distribution line 2 are connected from the branch point 3 via a watt-hour meter 8, and a data transmission device 10 is connected to the watt-hour meter 8. Data transmission devices 5, 7,
10 transmits the measurement data to the data receiving device 11 via a communication device such as wireless communication.
[0016]
The current values measured by the current detection devices 4 and 6 and the watt-hour meter 8 are associated with identification information for identifying the detected current detection device or watt-hour meter and the measured time information, and the data transmission device 5 , 7, and 10. The measurement data transmitted from the data transmission devices 5, 7, and 10 is received by the data reception device 11 and transmitted to the computer 12. The computer 12 that has received the measurement data performs a calculation for determining whether the power is stolen, as described later, and transmits the calculation result to the computer 13.
[0017]
As shown in FIG. 2, the computer 12 has position information 31 indicating the position of the substation, connection information 32 indicating the connection relationship between the substation and the distribution line, and demand indicating the relationship between the power consumer and the distribution line and the branch point. House information 33 and installation position information 34 indicating the installation position of the current detection device or the watt hour meter are stored in the storage device as the power distribution database 30. The measurement data transmitted from the data transmission devices 5, 7, and 10 is stored in the history information database 35 as history information associated with identification information and time information of the current detection device or the watt hour meter.
[0018]
The computer 12 monitoring whether or not power theft has been performed accumulates the measured data, and performs a calculation for checking whether or not the power has been stealed using the stored measured data. When the power customer 9 is designated, the power distribution database 30 is searched to search for the branch point 3 connected to the power customer 9 from the customer information, and the upstream side of the branch point 3 and the The current detection devices 4 and 6 installed on the downstream side are searched. Also, the power meter 8 installed between the branch point 3 and the power consumer 9 is searched. When the current detection devices 4 and 6 and the watt hour meter 8 arranged around the branch point 3 are specified in this way, the presence or absence of power theft is determined by the power theft detection method shown in FIG.
[0019]
As shown in FIG. 3, electric power is supplied from a substation 1 via a distribution line 2 to a power consumer 9 via a branch point 3. In the case where power is stolen by bypass, the power meter 8 that measures the power consumption of the power consumer 9 is connected before and after by a bypass line 20 to bypass the power meter 8. As described above, the current value I U flowing through the current detection device 4, the current value I D flowing through the current detection device 6, and the current value I WHM flowing through the watt hour meter 8 are measured. The time information is recorded in association with the time information. Either extract the current value of each current detection device and watt hour meter at the same time converted from the measured time information, or determine whether Equation 1 is satisfied using the average value of the measured values in the set period. I do. When the formula 1 is satisfied, there is a possibility that the bypass wire 20 is installed and the power is stolen.
[0020]
(Equation 1)
Figure 2004340767
The number 1 includes a current value I D of the downstream detection point of the branch point from the current value I U upstream detection point of the branch point, between the current detector 4 and a current detector 6 and the power meter 8 The value obtained by subtracting the generated leakage current value L is considerably larger than the current value I WHM flowing through the watt hour meter 8, which means that the current is flowing through the bypass line 20. This determination is made by setting a threshold value and determining whether the threshold value is larger than the threshold value. In the above, the case where power theft is described using the current value has been described. However, the same calculation can be performed using the electric energy to determine the power theft.
[0021]
In this way, the computer 12 monitors whether or not power theft is being performed. Based on this, a power trading method for preventing power theft can be performed.
[0022]
As shown in FIG. 2, the computer 13 calculates the electric power customer information 41 identifying and registering the electric power consumer, the meter reading data information 42 recording the electric power consumption for each electric power consumer, and the computer 12. Power theft determination information 43 in which the determined power theft is linked to the power consumer and recorded, discount incentives when the power is not being transmitted, penalties when the power is being transmitted, additional charges, and power supply Theft information corresponding to the treatment method is stored as a database.
[0023]
FIG. 4 is a diagram illustrating a flowchart in the power trading method of the present embodiment. In step 50, as described above, meter reading of power consumption and measurement of data for detecting power theft are performed monthly, weekly, daily, or periodically at a predetermined time. The measurement result of the data performed in step 50 is accumulated, and in step 51, the computer 12 determines whether or not power theft exists. If it is determined that the power has not been stolen, the result of the computer 12 is transmitted to the computer 13, and in step 52, the computer 13 performs a power rate calculation in consideration of the discount, and Based on this, charging and collection are performed in step 53. The determination of the presence or absence of theft is periodically repeated. If it is determined that the theft is not performed by referring to the theft determination information 43, the power purchase or sale is performed at the discounted electricity rate with reference to the theft corresponding information 44. Done.
[0024]
On the other hand, if the result of the determination on the presence or absence of power theft in step 51 is that the power is being stolen, the power company performs an on-site inspection and investigation on the presence or absence of the power theft in step 54. Based on the results of the site inspection and inspection, it is determined in step 55 whether the power theft is confirmed. As a result of the determination, if it is confirmed that the determination result of the power theft in step 51 is erroneous, the process returns to the routine in which the determination of the power theft in the step 51 is corrected to the fact that the power theft is not performed.
[0025]
If it is confirmed in step 55 that the power has been stolen, in step 56 the electric power company imposes a penalty on the electric power consumer. The penalty for the electric power consumer may be determined by referring to the power theft information 44, for example, by requesting an additional charge, restricting or stopping the electric power supply, depriving of the incentive for discounting the electric power charge, and the like.
[0026]
FIG. 5 is a diagram collectively showing the exchange between the electric power company and the electric power consumer described above.
[0027]
As shown in FIG. 5, the power company 100 normally supplies power 102 to a power consumer 101. The electric power company 100 obtains a license from the electric power consumer 101 before installing the electric power supply 102, and installs the electric energy meter 8 which is a detection device for monitoring the power theft. The power company 100 gives a discount incentive 104 for the power rate to the power customer 101 who has permitted the installation of the detection device. The power company 100 performs the power consumption meter reading 105, and calculates and discounts the power consumption measured by the power consumption meter reading 105 to the power consumer 101 by the computer 13 in consideration of the discount incentive of the power fee. An electric power billing 106 is performed. Upon receiving the discounted power rate bill 106, the power consumer 101 pays the power rate 107 to the power company 100 by automatic transfer or the like.
[0028]
According to the power trading method of the present embodiment, both the power company 100 and the power consumer 101 have the following merits.
[0029]
The advantage of the electric power consumer 101 is that if the electric power is supplied by a legal method, the electric power consumer 101 may pay a discounted electric power rate, so that the electric power cost can be reduced.
[0030]
In particular, since the power company 100 determines whether power is stolen or not, accurate determination of power theft, which has recently become a problem in the Asian region, is carried out, so that there is a risk of social sanctions including criminal liability and civil liability. Eliminates the need.
[0031]
On the other hand, the advantage of the electric power company 200 is that the collection rate of electric power is improved due to the reduction of power theft, and the electric power commercial loss can be reduced. Here, power commercial loss includes technical power loss caused by electrical resistance of power transmission and distribution equipment such as transformers, circuit breakers, and transmission and distribution lines, and power loss generated by other causes. One of them is power theft. In particular, theft of power causes a problem that power charges cannot be collected.
[0032]
The power company 100 can receive an economic advantage if the result of measurement during a certain set period indicates that the expression 2 is satisfied.
[0033]
(Equation 2)
Figure 2004340767
Here, for the sake of simplicity in Equation 2, the set period is set to one year, Fd is the accumulated amount for one year collected by discounting the electricity bill by applying this embodiment, and Fa is Cumulative amount for one year that can be collected without applying the example, I is the cumulative amount of investment for one year for installing a device to monitor theft by applying the present embodiment, and C is the applied amount for the present embodiment This is the annual running cost for system operation.
[0034]
According to the present embodiment, in addition to power theft due to unauthorized modification and use of the watt hour meter, it is possible to reliably detect power theft due to a bypass that was difficult to prevent, despite being a simple method, Accordingly, it is possible to reduce a power commercial loss and to improve a recovery rate of a power rate.
[0035]
In addition, by utilizing contract methods and systems, power customers who do not steal power are bought and sold in an advantageous manner such as discounting power rates, and penalties and additions are made for power customers who perform power theft. By providing measures for the charge and the power supply, it is possible to prevent the power consumers from theft, and to provide effective comprehensive antitheft measures.
[0036]
【The invention's effect】
Advantageous Effects of Invention According to the present invention, it is possible to reliably detect power theft of a power consumer without stopping power supply to the power consumer and causing a power outage. As a result, it is possible to reduce the power commercial loss of the power company.
