Description

本発明は電気機器への電力供給管理方法および電力管理ネットワークシステムに関し、より詳細には、需要家や電力会社等が電気機器の遠隔操作を行うための電気機器への電力供給管理方法および電力管理ネットワークシステムに関する。   The present invention relates to a power supply management method and a power management network system for an electrical device, and more specifically, a power supply management method and power management to an electrical device for a consumer, a power company, etc. to remotely operate the electrical device. Related to network system.

電力会社は、日中と夜間の電力消費量の差や夏季とそれ以外の季節の電力消費量の差を縮め電力消費量の平準化(負荷平準化)を図ることを目的として、(1)主として電気温水器や氷蓄熱システムを設置している住宅やオフィスビル等の夜間(例:夜11時から朝8時)の電気料金を昼間の電気料金よりも大幅に割引する料金体系、(2)電化住宅を対象としたオール電化割引が適用される料金体系、(3)電気温水器等を対象としたマイコン割引が適用される料金体系、(4)夏季やその他の季節の区分や平日・祝日区分による割引が適用される料金体系、など様々な種類の時間帯別契約を用意している。   Electric power companies aim to level out power consumption (load leveling) by reducing the difference in power consumption between daytime and nighttime and between summer and other seasons (1) A billing system that greatly discounts the electricity bill at night (eg from 11:00 pm to 8:00 am) compared to the daytime electricity bill, mainly in houses and office buildings where electric water heaters and ice heat storage systems are installed (2 ) Charge system to which all-electric discounts are applied to electrified houses, (3) Charge system to which microcomputer discounts are applied to electric water heaters, etc. (4) Summer and other season categories and weekdays / There are various types of time-based contracts, such as a charge system that applies discounts according to holidays.

しかし折角時間帯別契約を結んだ需要家であっても、料金メリットのある時間帯に電気機器を使用しようとする意識が日々の生活の中で徐々に希薄となり、その結果夜間電力を利用して稼動させても支障のない電気機器であっても夜間以外に使用されることも多いのが実情である。このような場合には需要家は時間帯別契約のメリットを十分享受できないことになる。
また安い夜間電力を使用するために、需要家が電気機器に内蔵したタイマーをセットすることにより電気温水器や食器洗浄器、洗濯機の稼動を夜間の一定の時間に行わせるようにすることも多いが、電気機器の内部時計が狂い高い電気料金の時間帯にこれらの電気機器が稼動してしまい、需要家が不本意に高い電気料金を支払わなければならない場合もあった。
However, even customers who have signed contracts according to the time of the day, the consciousness of using electrical equipment in the time zone where there is a charge merit gradually dilutes in daily life, and as a result, the use of night electricity Even if it is an electrical device that does not interfere with operation, it is often used outside the night. In such a case, the customer cannot fully enjoy the merits of the hourly contract.
In addition, in order to use cheap nighttime electricity, consumers can set up a built-in timer in the electric equipment so that the electric water heater, dishwasher, and washing machine are operated at a certain time of the night. In many cases, however, the internal clock of the electric device is crazy and these electric devices are operated during a period of high electric charges, and the customer has to pay unintentionally high electric charges.

また電力会社は上記時間帯別契約を用意して電力負荷平準化を図っているが、より一層の電力負荷平準化を達成するためには、配電線のフィーダ毎の電力負荷が均等になることが望まれる。   In addition, power companies have prepared the above-mentioned contracts by time zone to achieve power load leveling, but in order to achieve even more power load leveling, the power load for each feeder of the distribution line must be equalized. Is desired.

そのため電力消費量の平準化と、深夜電力機器のタイムスイッチや夜間電力量計等の設置・配線を不要とすることを目的とした、例えば特許文献1の「深夜電力機器及び深夜電力機器のホームネットワークシステム」のように、電力会社のホストコンピュータから送信される機器の運転許可・禁止の指令を受けることにより機器の使用時間帯をコントロールする技術等も発案されている。
特開2003−42556
For this reason, for example, “Home of late-night power equipment and late-night power equipment” disclosed in Patent Document 1 is aimed at leveling power consumption and eliminating the need for installation / wiring of a time switch or nighttime electricity meter of a late-night power equipment. As in the case of a “network system”, a technique for controlling the use time zone of a device by receiving an operation permission / prohibition command transmitted from a host computer of an electric power company has been proposed.
JP 2003-42556 A

しかしながら上記特許文献1に記載の発明では、タイムスイッチや深夜電力量計等を不要とすることができるといった点では優れているものの、電力会社が電気機器の運転許可・禁止を行うため、例えば需要家が昼間に電気温水器を追い炊きしたい場合にもその使用をすることができないといった問題があった。
また特許文献1に記載の発明は主に電気温水器や蓄熱暖房機の制御を目的としたものであるため、それ以外の電気機器についてはその制御を行えるものではなかった。
However, although the invention described in Patent Document 1 is excellent in that a time switch, a midnight electricity meter, and the like can be dispensed with, an electric power company permits / prohibits operation of electrical equipment. There is a problem that the house cannot be used even if the house wants to cook an electric water heater in the daytime.
In addition, the invention described in Patent Document 1 is mainly intended for control of an electric water heater or a regenerative heater, and therefore other electric devices cannot be controlled.

本発明は上記問題を解決するためになされたもので、その第1の目的は、電気機器全般の運転を制御することができる電気機器への電力供給管理方法および電力管理ネットワークシステムを提供することにある。
本発明の第2の目的は、需要家にできるだけ料金メリットのある時間帯に電気機器を使用してもらうことで電力負荷の平準化を達成することにある。
The present invention has been made to solve the above problems, and a first object of the present invention is to provide a power supply management method and a power management network system for electrical equipment that can control the operation of the electrical equipment in general. It is in.
A second object of the present invention is to achieve leveling of electric power load by having a consumer use an electric device in a time zone having a merit as much as possible.

[Mainly when the customer wants to cut off the power supply to electrical equipment during a specific time period (eg, weekdays when absent)]
(1) Step 1, Step 2—Electrical equipment registration stage (S1), Energizing time designation stage (S2)
This stage is a stage in which each consumer wants to manage the power supply using a communication terminal such as a personal computer owned by the customer, and the time zone for energizing each electrical instrument is registered in the management server of the management center. is there.
The customer 1 first browses a homepage prepared for registering the electrical device 22 connected to each outlet 18 in the management server 24 of the management center 3 via the Internet using a personal computer, and is given in advance. Log in to the member registration page using your member ID and password. The management server 24 knows the number of branch wires 16 extending from the distribution board 14 of the consumer's dwelling unit and the number assigned to each branch wire. On the member registration page, each outlet 18 at the end of each branch wire. A number is displayed, and an electric device 22 connected to each outlet and a connected electric device column and an energized desired time zone column in which a day of the week and a desired energization time zone Tz for energizing the electric device can be input are provided.
The consumer 1 grasps the number printed on the outlet 18 to which the electric device 22 is connected, and then selects the type of the electric device 22 to be connected to the outlet for which power supply is to be managed, and the corresponding outlet on the member registration page. Register the number in the connected electrical equipment column. Further, for a time zone in which energization (power supply) is desired for the selected electrical device, the time zone is entered in the desired energization time zone field.
Specifically, for example, in the connected electrical equipment column, select the corresponding electrical equipment from the pull-down menu that describes lighting, TV, stereo, personal computer, air conditioning equipment, cooking utensils, etc., and enter the desired energization time zone field. If you want to cut off the power supply from 8:00 am to 5:00 pm on weekdays and supply power only from 5:00 pm on weekdays to 8:00 am the following day, Select from the pull-down menu and enter.
In addition, even in the case of electrical equipment with an internal clock such as a video recorder, a built-in backup battery that can maintain data such as operation of the internal clock and recording reservation in case the power supply is cut off In such a case, it is possible to manage the supply of electric power in the same manner as the electric devices such as the lighting.
It should be noted that electrical equipment such as a vacuum cleaner, home security device, answering machine, interphone, etc. that does not need to manage the power supply, and a vacuum cleaner etc. are connected only when necessary without being normally used. There is no need to make any settings for the outlet.
In addition, instead of the user himself / herself performing registration work and time input for various electrical devices connected to each outlet, the staff of the management center or the like may input it by listening to the customer.
(2) Step 3-Energization instruction stage (S3)
This stage is a stage where the management server of the management center permits the supply of electric power to the consumer's electrical equipment through the Internet.
The management server 24 becomes the energization start time set for each outlet 18 based on the information (desired energization time zone Tz) registered in the server at the electrical device registration stage (S1) and the energization time designation stage (S2). At the time, an energization start signal T1 is transmitted to the receiving device 36 (accommodated in the distribution board) installed in the dwelling unit of the customer 1 through the Internet. The receiving device 36 that has received the energization start signal T1 determines which branch wiring 16 the received signal is for allowing energization, and the distribution board that controls the energization to the corresponding branch wiring. A switch switching signal is transmitted to the switching device 38.
(3) Step 4-Energization execution stage (S4)
This stage is a stage in which the switching device of the distribution board starts energizing the branch wiring.
The switching device 38 that has received the switching signal from the receiving device 36 switches the switch for energizing / cutting off the branch wiring 16 to energize the corresponding branch wiring.
The electric device 22 connected to the outlet 18 at the end of the branch wiring where the energization is started becomes operable at the same time as the energization is started.
(4) Step 5-Blocking Instruction Stage (S5)
In this stage, the management server of the management center instructs the power distribution board of the customer's power usage facility to cut off the power through the Internet.
When the management server 24 becomes the energization cutoff time set for each outlet 18 based on the information (desired energization time zone Tz) registered in the electrical device registration stage (S1) and the energization time designation stage (S2). In addition, the power cut-off signal T2 is transmitted to the receiving device 36 (accommodated in the distribution board) installed in the dwelling unit of the customer 1 through the Internet. The receiving device that has received the energization cut-off signal T2 determines which branch wiring 16 the received signal is for cutting off the energization of the distribution board 14 that controls energization to the corresponding branch wiring. A switch switching signal is transmitted to the switching device 38.
(5) Step 6-Blocking execution stage (S6)
This stage is a stage where the switching device of the distribution board cuts off the power supply to the branch wiring.
The switching device 38 that has received the switching signal from the receiving device 36 switches a switch for energizing / interrupting the branch wiring 16 to interrupt the energization to the corresponding branch wiring.
The electrical device 22 connected to the outlet 18 at the end of the branch wiring where the energization has started is changed from the standby state to the stop state at the same time as the energization is cut off. Its operation is maintained by the built-in backup battery.

以上説明した電力供給管理方法によれば、平日日中などの不在時における所望の電気機器への電力の供給を遠隔制御することができ、スイッチの消し忘れによる火災発生の防止や、待機電力の不要化による省エネ等に貢献することができる。なお、必要な場合には手動操作によって電気機器に電力を供給してやることもできるため不便はない。   According to the power supply management method described above, it is possible to remotely control the supply of power to a desired electrical device when it is absent such as during weekdays, preventing the occurrence of fire due to forgetting to turn off the switch, It can contribute to energy saving by making it unnecessary. Note that there is no inconvenience since electric power can be supplied to the electric device by manual operation when necessary.

[Mainly when customers want to drive electrical equipment during nighttime power hours]
(1) Step 1, Step 2—Electrical equipment registration stage (S1), Operation start time designation stage (S2 ′)
In this stage, as in the first embodiment, the customer wants to manage the electrical equipment that the consumer wants to manage the power supply using a communication terminal such as a personal computer and the time when the electrical equipment starts to be energized to the management server of the management center. It is a registration stage.
The electrical device registration stage (S1) is basically the same as that of the first embodiment, but the electrical device 22 registered here is an electric water heater or dishwasher that can be operated using nighttime power. , Washing machines and various charging devices. These electric devices 22 are set so as to start the operation at the same time as power is supplied, and the operation is terminated after a certain time has elapsed since the operation was started.
In the operation start time designation stage (S2 ′), the customer inputs the time at which the selected electric device 22 is desired to be started into the operation start time designation field prepared on the member registration page.
Specifically, for example, in the connected electrical equipment column, an electrical device that can be operated using nighttime power, such as an electric water heater or a dishwasher, is included in a pull-down menu for each outlet to which the electrical device is connected. In the operation start time designation field, the time at which the operation of the selected electrical device is to be started is selected and input from the pull-down menu in the time from 11:00 pm to 8:00 am the next day.
In addition, instead of the customer performing registration work and time input for various electric devices connected to each outlet, the staff of the management center may input the information by listening to the customer.
(2) Step 3-Energization instruction stage (S3)
This stage is a stage in which the management server of the management center permits the supply of electric power to the consumer's electrical equipment through the Internet, and is the same as the energization instruction stage (S3) of the first embodiment, and the description thereof is omitted. .
(3) Step 4-Energization execution stage (S4)
This stage is a stage at which the switching device of the distribution board starts energizing the branch wiring, and since it is the same as the energization execution stage (S4) of the first embodiment, the description thereof is omitted.
(4) Step 5-energization cutoff stage (S6 ')
This stage is a stage in which the supply of electric power to the electrical equipment that has finished operating is shut off.
The electrical device 22 that has finished operating after a certain time has elapsed since the start of operation is in a so-called standby state that waits for the next operation instruction while consuming a small amount of power. The switch is switched so that the 14 switching devices 38 cut off the energization to the corresponding branch wiring. Whether or not the electrical equipment connected to the outlet 18 is in a standby state is determined by checking that the power flowing through the branch wiring connected to the outlet is a predetermined time (for example, 10 minutes) or more and a predetermined reference value (for example, 5 watts) or less. When it becomes, it is assumed that it is in a standby state.
(5) Step 6-Blocking execution stage (S6)
This stage is a stage in which the switching device of the distribution board ends energization to the branch wiring. When the switch is switched, the energization to the corresponding branch wiring is cut off and connected to the outlet 18 at the end of the branch wiring. The electrical device 22 thus changed from the standby state to the stopped state simultaneously with the interruption of the energization.

以上説明した電力供給管理方法によれば、夜間に運転することができる電気機器を深夜電力の時間帯に確実に使用してもらうことができ、需要家には割安な深夜電力による料金メリットと共に待機電力の不要化による省エネによる料金メリットを、電力会社には電力負荷平準化というメリットを付与することができる。   According to the power supply management method described above, electric devices that can be operated at night can be used reliably in the nighttime power hours, and customers can wait with the benefits of cheap late-night power. It is possible to give the benefit of energy savings by eliminating the need for electric power, and the benefit of power load leveling to the power company.

(1)ステップ1、ステップ2−電気機器登録段階(S1)、運転完了時刻登録段階(S2”)
この段階は、需要家のパソコン等の通信端末を用いて電力供給を管理したい電気機器および各電気機器の運転の完了期限である運転完了時刻(Tf)を管理センタの管理サーバに登録する段階である。
電気機器登録段階(S1)は上記実施例1と基本的に同様のものであるが、ここで登録される電気機器22は主として夜間電力を利用して運転することができる電気温水器、食器洗浄器、洗濯機、各種充電装置などである。これらの電気機器22は電力が供給されると同時にその運転を開始するように設定され、運転を開始してから一定時間の経過後にはその運転を終了する。
運転完了時刻登録段階(S2”)では、需要家1が会員用登録ページに用意された運転完了期限指定欄に、選択した電気機器22の運転をそのときまでに完了しておきたい時刻を入力する。具体的には、例えば、電気温水器については午前6時までに、食器洗浄器については午前7時までに、洗濯機については午前8時までに運転を完了したい場合にはその時刻を運転完了期限指定欄に入力する。
なお各コンセントに接続される各種電気機器の登録作業や時刻の入力を需要家自身が行う代わりに、管理センタの職員等が需要家から聞き取ることによってこれを入力してやってもよい。
(2)ステップ3−通電指示段階(S3’)
この段階は、管理センタの管理サーバがインターネットを通じて需要家の電気機器への電力の供給を許可する段階である。
電力会社5からは管理サーバ24に、需要家の電力使用施設12がある地域における配電負荷傾向のデータが送られ、このデータに基づき上記運転完了時刻登録段階S2”で登録された時刻までに該当する電気機器の運転が完了するように、管理サーバ24が複数の電気機器22の運転時間を調整し、インターネットを通じて各電力使用施設の受信装置36に通電開始信号T1を送信する。具体的には例えば電気温水器の運転完了時刻Tfが午前6時とされている場合、電気温水器の必要十分な運転時間(水の沸き上げ時間)を約5時間とすると、この電気温水器に電力を供給する分岐配線16への通電開始時刻は、午後11時から翌午前1時までの間の適当な時刻を配電負荷を考慮して管理サーバが決定する。
なお電気機器の運転を確実に完了させるために、推測される運転時間に一定の付加時間(30分程度)を付加した上で通電開始時刻を逆算してこれを決定してやることも好ましい。
通電開始信号T1を受信した受信装置36は、受信した信号がどの分岐配線16への通電を許可するためのものであるかを判別し、該当する分岐配線への通電を制御する分電盤14のスイッチング装置38へスイッチの切替信号を送信する。
(3)ステップ4−通電実行段階(S4)
この段階は、分電盤のスイッチング装置が分岐配線への通電を始める段階であり、上記実施例1の通電実行段階(S4)と同様であるためその説明を省略する。
(4)ステップ5−遮断指示段階(S5)
この段階は、管理センタの管理サーバがインターネットを通じて需要家の電力使用施設の分電盤に電力遮断を指示する段階である。
管理サーバ24は、電気機器登録段階(S1)で登録した各電気機器22が、その運転を完了するまでに必要十分な時間だけ通電開始時刻から経過した後に、インターネットを通じて需要家の住戸に設置された受信装置36に通電遮断信号T2を送信する。通電遮断信号T2を受信した受信装置36は、受信した信号がどの分岐配線16への通電遮断を指示するものであるかを判別し、該当する分岐配線への通電を制御する分電盤14のスイッチング装置38へスイッチの切替信号を送信する。
(5)ステップ6−遮断実行段階(S6)
この段階は、分電盤のスイッチング装置が分岐配線への通電を終了する段階であり、上記実施例1の遮断実行段階(S6)と同様であるためその説明を省略する。

[Mainly when electric power companies want to promote power load leveling-part 1]
(1) Step 1, Step 2—Electrical equipment registration stage (S1), Operation completion time registration stage (S2 ″)
This stage is a stage in which the electric equipment that is desired to manage the power supply using a communication terminal such as a personal computer of the consumer and the operation completion time (Tf) that is the operation completion date of each electric apparatus are registered in the management server of the management center. is there.
The electric device registration stage (S1) is basically the same as that of the first embodiment, but the electric device 22 registered here is an electric water heater and a dishwasher that can be operated mainly using nighttime power. Appliances, washing machines, various charging devices. These electric devices 22 are set to start the operation at the same time as the electric power is supplied, and the operation ends after a certain time has elapsed since the operation was started.
In the operation completion time registration stage (S2 ″), the time at which the customer 1 wants to complete the operation of the selected electrical device 22 by that time is entered in the operation completion deadline designation field prepared on the member registration page. Specifically, for example, if you want to complete the operation by 6 am for an electric water heater, 7 am for a dishwasher, or 8 am for a washing machine, set the time. Enter in the operation completion deadline designation field.
In addition, instead of the customer performing registration work and time input for various electric devices connected to each outlet, the staff of the management center may input the information by listening to the customer.
(2) Step 3-Energization instruction stage (S3 ')
This stage is a stage where the management server of the management center permits the supply of electric power to the consumer's electrical equipment through the Internet.
The electric power company 5 sends the distribution load trend data in the area where the customer's power use facility 12 is located to the management server 24, and the data is registered by the time registered in the operation completion time registration step S2 ″ based on this data. The management server 24 adjusts the operation time of the plurality of electric devices 22 so that the operation of the electric devices to be performed is completed, and transmits an energization start signal T1 to the receiving device 36 of each power usage facility via the Internet. For example, if the operation completion time Tf of the electric water heater is 6:00 am and the necessary and sufficient operation time of the electric water heater (water boiling time) is about 5 hours, power is supplied to the electric water heater. The management server determines an appropriate time between 11:00 pm and 1 am the next time to start the energization of the branch wiring 16 to be performed in consideration of the distribution load.
In order to surely complete the operation of the electric device, it is also preferable to add a certain additional time (about 30 minutes) to the estimated operation time and then reversely calculate the energization start time to determine this.
The receiving device 36 that has received the energization start signal T1 determines which branch wiring 16 the received signal is for permitting energization, and controls the distribution board 14 that controls energization to the corresponding branch wiring. The switching signal of the switch is transmitted to the switching device 38.
(3) Step 4-Energization execution stage (S4)
This stage is a stage at which the switching device of the distribution board starts energizing the branch wiring, and since it is the same as the energization execution stage (S4) of the first embodiment, the description thereof is omitted.
(4) Step 5-Blocking Instruction Stage (S5)
In this stage, the management server of the management center instructs the power distribution board of the customer's power usage facility to cut off the power through the Internet.
The management server 24 is installed in the customer's dwelling unit through the Internet after each electric device 22 registered in the electric device registration stage (S1) has passed from the start time of energization for a necessary and sufficient time to complete its operation. The energization cutoff signal T2 is transmitted to the receiving device 36. The receiving device 36 that has received the power cut-off signal T2 determines which branch wiring 16 the received signal instructs to cut off the power supply, and controls the distribution board 14 that controls the power supply to the corresponding branch wiring. A switch switching signal is transmitted to the switching device 38.
(5) Step 6-Blocking execution stage (S6)
This stage is a stage in which the switching device of the distribution board ends energization to the branch wiring, and since it is the same as the cutoff execution stage (S6) of the first embodiment, the description thereof is omitted.

以上説明した電力供給管理方法によれば、運転完了時刻までに運転を完了すればよい電気機器の運転時間を管理サーバが管理することができるので、その地域の配電負荷が均等になるように電力会社が時間帯別の電力需要をコントロールすることができる。   According to the power supply management method described above, since the management server can manage the operation time of the electrical equipment that only needs to be completed before the operation completion time, power can be distributed so that the distribution load in the region is equalized. The company can control power demand by time of day.

[主に電力会社5が電力負荷平準化を促進したい場合−その2]
本実施例では上記実施例3の遮断指示段階(S5)における管理サーバ24からの通電遮断信号T2による所定の分岐配線16への通電遮断に代え、実施例2の通電遮断段階(S6’)と同様に、分岐配線に流れる電力量から電気機器22の運転完了を判断し、かかる分岐配線への通電を分電盤14のスイッチング装置38が遮断するものである。なおその他の段階は上記実施例3と同様であるため、その説明を省略する。

[Mainly when electric power company 5 wants to promote electric power load leveling-part 2]
In this embodiment, instead of turning off the power to the predetermined branch wiring 16 by the turn-off signal T2 from the management server 24 in the turn-off instruction step (S5) of the third embodiment, the turn-off step (S6 ′) of the second embodiment and Similarly, the completion of the operation of the electrical device 22 is determined from the amount of power flowing through the branch wiring, and the switching device 38 of the distribution board 14 cuts off the power supply to the branch wiring. Since other steps are the same as those in the third embodiment, description thereof is omitted.

以上説明した電力供給管理方法によれば、実施例3と同様に、管理サーバ24からの指示によってその地域の配電負荷を均等することができることに加え、管理サーバ24による通電遮断信号T2の送信を不要とすると共に電気機器22への通電時間を最小限にすることができる。   According to the power supply management method described above, in the same manner as in the third embodiment, in addition to being able to equalize the distribution load in the area by an instruction from the management server 24, the management server 24 transmits the power cut-off signal T2. It is unnecessary and the energization time to the electric device 22 can be minimized.

なお上述した実施例1乃至4の何れについても、通電が遮断された分岐配線16に手動操作により通電を許可する通電許可機構42を用い、需要家の必要に応じて柔軟に電気機器22の運転を可能とする段階を含めることができる。   In any of the first to fourth embodiments described above, the energization permission mechanism 42 that permits energization by manual operation to the branched wiring 16 that has been de-energized is used to flexibly operate the electrical device 22 as required by the customer.
