Description

本発明は、商用電源等の給電系統の停電時における分電に関し、例えば、停電時、ハイブリッド車等の給電機能を活用するインテリジェント分電盤、分電装置、停電対策システム及び分電方法に関する。
The present invention relates to power distribution at the time of a power failure of a power supply system such as a commercial power supply, and relates to, for example, an intelligent distribution board, a power distribution device, a power failure countermeasure system, and a power distribution method that utilize a power supply function of a hybrid vehicle or the like.

家屋等の建物には商用電源に代表される給電系統から需要者に対して必要な電力が供給されている。この電力供給は例えば、屋内配線母線から分電盤の主幹ブレーカに導かれ、この主幹ブレーカから複数の分岐ブレーカを経て屋内配線の複数の分岐線に導かれ、屋内の機器に電力が供給される。   A building such as a house is supplied with necessary power from a power supply system represented by a commercial power source to consumers. For example, this power supply is led from the indoor wiring bus to the main breaker of the distribution board, and from the main breaker to the plurality of branch lines of the indoor wiring through the plurality of branch breakers, and power is supplied to the indoor equipment. .

ところで、商用電源等の給電系統が停電した場合、電気自動車やハイブリッド車等に搭載された蓄電池や発電機能を利用した補助的な給電の利用が考えられる。このような補助的な給電を給電系統に直結した場合、給電系統が復旧した際に補助給電を継続すると補助給電が直接給電系統に流れ込むことにより、給電系統の安定的な給電に対して大きな影響を与えることになる。このため、従来の分電盤では、給電系統の停電時、蓄電池、太陽電池、燃料電池等の分散型電源から給電供給への切替えを行うことが出来なかった。   By the way, when a power supply system such as a commercial power supply fails, it is conceivable to use auxiliary power supply using a storage battery or a power generation function mounted on an electric vehicle, a hybrid vehicle, or the like. When such auxiliary power supply is directly connected to the power supply system, if the auxiliary power supply is continued when the power supply system is restored, the auxiliary power supply flows directly into the power supply system, which greatly affects the stable power supply of the power supply system. Will give. For this reason, in the conventional distribution board, it was not possible to switch from a distributed power source such as a storage battery, a solar cell, or a fuel cell to power supply during a power failure in the power supply system.

従来のインテリジェントな分電盤では、給電系統からの電力で稼動する構成であり、系統の停電時には制御機能や通信機能が停止する不都合があった。   The conventional intelligent distribution board is configured to operate with power from the power supply system, and has a disadvantage that the control function and the communication function are stopped in the event of a power failure of the system.

〔第１の実施の形態〕 [First Embodiment]

第１の実施の形態は、停電対策システムであって、本発明のインテリジェント分電盤を備えた構成例である。   1st Embodiment is a power failure countermeasure system, Comprising: It is a structural example provided with the intelligent distribution board of this invention.

本発明の第１の実施の形態について、図１を参照する。図１は停電対策システムの一例を示している。   For the first embodiment of the present invention, reference is made to FIG. FIG. 1 shows an example of a power failure countermeasure system.

この停電対策システム２は、本発明の停電対策システムの一例であって、家屋４の内部に既存の住宅用分電盤６を備え、家屋４の外壁に拡張分電盤８を備えている。拡張分電盤８は、本発明のインテリジェント分電盤の一例である。この場合、電力系統１０は給電系統の一例であるが、自家発電等の給電系統を用いてもよい。   The power failure countermeasure system 2 is an example of the power failure countermeasure system of the present invention, and includes an existing residential distribution board 6 inside the house 4 and an extended distribution board 8 on the outer wall of the house 4. The extended distribution board 8 is an example of the intelligent distribution board of the present invention. In this case, the power system 10 is an example of a power feeding system, but a power feeding system such as private power generation may be used.

分電盤６は、電力系統１０からの受電手段の一例であって、電力系統１０から受電し、負荷１２のうち一般負荷１２Ａへの給電、拡張分電盤８への給電、充放電コンセント１４への給電を行う。一般負荷１２Ａは、洗濯機、テレビ等、家電製品が含まれる。充放電コンセント１４は、電力系統１０からのハイブリッド車１６（以下「ＨＥＶ１６」と称する。）への充電出力、ＨＥＶ１６からの放電出力を受ける手段の一例である。   The distribution board 6 is an example of power receiving means from the power system 10. The distribution board 6 receives power from the power system 10, supplies power to the general load 12 </ b> A of the load 12, supplies power to the extended distribution board 8, and a charge / discharge outlet 14. Supply power to The general load 12A includes home appliances such as a washing machine and a television. The charging / discharging outlet 14 is an example of means for receiving a charging output from the electric power system 10 to the hybrid vehicle 16 (hereinafter referred to as “HEV 16”) and a discharging output from the HEV 16.

拡張分電盤８は、電力系統１０の停電時、ＨＥＶ１６の接続に基づき、蓄電池１８の放電による電力を充放電コンセント１４から受電し、負荷１２のうち特定負荷１２Ｂに給電する。そこで、この拡張分電盤８には、電力系統１０の停電検出機能と、停電検出時、通信部２０により停電情報をＨＥＶ１６等に通知する機能とを備えている。特定負荷１２Ｂには、電灯、冷蔵庫、エアコン等、停電を回避したい負荷が含まれる。   The expansion distribution board 8 receives power from the discharge of the storage battery 18 from the charging / discharging outlet 14 based on the connection of the HEV 16 at the time of a power failure of the power system 10, and supplies the specific load 12 </ b> B among the loads 12. Therefore, the extended distribution board 8 has a power failure detection function of the power system 10 and a function of notifying the HEV 16 of power failure information by the communication unit 20 when a power failure is detected. The specific load 12B includes a load such as an electric light, a refrigerator, and an air conditioner that is desired to avoid a power failure.

ＨＥＶ１６は、分散型電源の一例であって、既述の蓄電池１８、通信部２２とともに、電子制御ユニット（ＥＣＵ）２４、コンバータ（ＤＣ→ＡＣ、ＡＣ→ＤＣ）２６、インバータ２８、モータ３０等を備えている。通信部２２は既述の通信部２０と無線又は有線により接続され、電力系統１０の停電時、通信部２０からの停電通知を受け、ＥＣＵ２４に電力系統１０の停電を通知する。ＥＣＵ２４は、インバータ２８、モータ３０等のＨＥＶ１６の制御の他、停電時、コンバータ２６を動作させる。コンバータ２６には充放電ケーブル３１及び充放電プラグ３２が接続され、この充放電プラグ３２が充放電コンセント１４に接続される。従って、通常時には、充放電コンセント１４から充放電プラグ３２を介して電力系統１０からの電力が蓄電池１８に給電されるが、電力系統１０の停電時には、蓄電池１８の放電によるコンバータ２６の出力が充放電プラグ３２から充放電コンセント１４に給電される。   The HEV 16 is an example of a distributed power source, and includes the storage battery 18 and the communication unit 22 described above, an electronic control unit (ECU) 24, a converter (DC → AC, AC → DC) 26, an inverter 28, a motor 30, and the like. I have. The communication unit 22 is connected to the above-described communication unit 20 wirelessly or by wire, and receives a power failure notification from the communication unit 20 when the power system 10 fails, and notifies the ECU 24 of the power system 10 power failure. The ECU 24 controls the HEV 16 such as the inverter 28 and the motor 30 and operates the converter 26 during a power failure. A charge / discharge cable 31 and a charge / discharge plug 32 are connected to the converter 26, and the charge / discharge plug 32 is connected to the charge / discharge outlet 14. Therefore, normally, power from the power system 10 is supplied from the charging / discharging outlet 14 to the storage battery 18 via the charging / discharging plug 32, but when the power system 10 is powered down, the output of the converter 26 is charged by the discharge of the storage battery 18. Power is supplied from the discharge plug 32 to the charge / discharge outlet 14.

コンバータ２６は、電力系統１０からの交流ＡＣを直流ＤＣに変換して蓄電池１８を充電する機能と、蓄電池１８の放電出力である直流ＤＣを交流ＡＣに変換して出力する機能とを備えている。このような機能は、ＥＣＵ２４によって切り替えられる。   The converter 26 has a function of converting the AC AC from the power system 10 into DC DC and charging the storage battery 18, and a function of converting DC DC, which is a discharge output of the storage battery 18, into AC AC and outputting the same. . Such a function is switched by the ECU 24.

なお、蓄電池１８の放電出力はインバータ２８を介してモータ３０に加えられ、走行出力に変換される。   In addition, the discharge output of the storage battery 18 is applied to the motor 30 via the inverter 28, and is converted into a travel output.

斯かる構成では、通常時、電力系統１０から家屋４内の負荷１２の一般負荷１２Ａに給電するともに、拡張給電盤８に給電する。この場合、分電盤６から充放電コンセント１４に給電されるので、充放電プラグ３２を接続すれば、ＨＥＶ１６の蓄電池１８が電力系統１０からの電力によって充電される。   In such a configuration, power is supplied to the general load 12 </ b> A of the load 12 in the house 4 from the power system 10 and power is supplied to the expansion power supply panel 8 at normal times. In this case, since power is supplied from the distribution board 6 to the charging / discharging outlet 14, the storage battery 18 of the HEV 16 is charged by the electric power from the power system 10 when the charging / discharging plug 32 is connected.

また、停電時には、拡張分電盤８に対する電力系統１０からの給電が停止されるので、その停電を通信部２０から通知し、この通知により通信部２２はＨＥＶ１６のＥＣＵ２４に停電を通知する。ＥＣＵ２４はコンバータ２６を動作させ、蓄電池１８を放電状態に切り替える。蓄電池１８の放電はコンバータ２６によって交流出力に変換され、この放流出力は充放電プラグ３２及び充放電コンセント１４を介して拡張分電盤８に供給される。蓄電池１８の放電により、負荷１２の特定負荷１２Ｂに対する給電が開始される。停電時の不都合が解消される。   Moreover, since the power supply from the power system 10 to the extended distribution board 8 is stopped at the time of a power failure, the power failure is notified from the communication unit 20, and the communication unit 22 notifies the ECU 24 of the HEV 16 of the power failure by this notification. The ECU 24 operates the converter 26 and switches the storage battery 18 to a discharged state. The discharge of the storage battery 18 is converted into an AC output by the converter 26, and this discharge output is supplied to the extended distribution board 8 through the charge / discharge plug 32 and the charge / discharge outlet 14. Power supply to the specific load 12 </ b> B of the load 12 is started by discharging the storage battery 18. Inconvenience at the time of power failure is eliminated.

そして、電力系統１０の復旧時には、負荷１２の一般負荷１２Ａには電力系統１０からの給電が開始され、通信部２０からの復旧通知によりＨＥＶ１６からの給電が解除される。このとき、ＨＥＶ１６の蓄電池１８は充電が開始される。   When the power system 10 is restored, power supply from the power system 10 is started to the general load 12 </ b> A of the load 12, and power supply from the HEV 16 is canceled by a recovery notification from the communication unit 20. At this time, charging of the storage battery 18 of the HEV 16 is started.

〔第２の実施の形態〕 [Second Embodiment]

第２の実施の形態は住宅用分電盤６及び拡張分電盤８の構成について開示している。   The second embodiment discloses the configuration of the residential distribution board 6 and the extended distribution board 8.

The electromagnetic switch 42 is an example of a first switching means installed in a power feeding unit (first power feeding unit) connected to the power feeding system 10 side, and is turned off when the power system 10 is powered down (when the system is shut down). However, it has a holding function of, for example, 1 to 4 [seconds] at the moment of power failure.

The electromagnetic switch 44 is a means that is switched to the ON state at the time of a power failure of the power system 10 (when the system is cut off) and supplies power to the specific load 12B from the distributed power source.

As shown in FIG. 3, when a power failure occurs for a certain time exceeding a momentary power failure for several seconds (step S11), the electromagnetic switch 42 is turned off. (Interruption of the electric power system 10), the electromagnetic switch 44 is turned on (connection of HEV 16) (step S12).

電磁開閉器４２のＯＦＦを検知し、通信部２０により停電発生を無線通信でＨＥＶ１６に通知する（ステップＳ１３）。ＨＥＶ１６の電力が供給され、特定負荷１２Ｂが稼働する（ステップＳ１４）。   The OFF of the electromagnetic switch 42 is detected, and the occurrence of a power failure is notified to the HEV 16 by wireless communication by the communication unit 20 (step S13). The power of the HEV 16 is supplied and the specific load 12B is activated (step S14).

電力系統１０からの給電が復旧した後、手動復帰ボタン４６が押された場合（ステップＳ１５）、電磁開閉器４４がＯＦＦ（ＨＥＶ１６の遮断）、電磁開閉器４２がＯＮ（電力系統１０の復帰）となり（ステップＳ１６）、電力系統１０からの給電が行われる。   After the power supply from the power system 10 is restored, when the manual return button 46 is pressed (step S15), the electromagnetic switch 44 is turned off (the HEV 16 is shut off), and the electromagnetic switch 42 is turned on (the power system 10 is restored). (Step S16), power is supplied from the power system 10.

斯かる構成によれば、既存の住宅用分電盤６に拡張分電盤８を併設すれば、既存の分散型電源を停電時の補助給電に活用し、特定負荷１２Ｂの家電機器が停電時に使用不能となる不都合を回避でき、利便性が高められる。   According to such a configuration, if the expansion distribution board 8 is provided in addition to the existing residential distribution board 6, the existing distributed power source is utilized for auxiliary power supply in the event of a power failure, and the home appliance with the specific load 12B is in the event of a power failure. The inconvenience of being unusable can be avoided, and convenience is enhanced.

I have.

通信部２０は、停電検出回路５６、ＣＰＵ（Central Processing Unit ）５８及び通信モジュール６０を備えている。停電検出回路５６は、既述の停電検出部５４の停電検出を認識する認識手段の一例であり、その認識出力をＣＰＵ５８に通知する。ＣＰＵ５８は、通信モジュール６０の制御手段の一例であって、電力系統１０の停電時、その停電情報をアンテナ６２を通じて無線により通知する。通信部２０には、電力系統１０と独立した動作を確保するため、電池６４が接続され、電力系統１０が遮断されても、停電検出及び停電通知を行うことができる。   The communication unit 20 includes a power failure detection circuit 56, a CPU (Central Processing Unit) 58, and a communication module 60. The power failure detection circuit 56 is an example of a recognition unit that recognizes the power failure detection of the power failure detection unit 54 described above, and notifies the CPU 58 of the recognition output. The CPU 58 is an example of a control unit of the communication module 60, and notifies the power failure information wirelessly through the antenna 62 when the power system 10 is powered down. Even if the battery 64 is connected to the communication unit 20 to ensure an operation independent of the power system 10 and the power system 10 is shut off, the power failure detection and power failure notification can be performed.

電磁開閉器４２は、励磁コイル４２１、遅延回路４２２、接点４２３、４２４、４２５を備えている。電磁開閉器４４は、励磁コイル４４１、接点４４２、４４３を備えている。配電線５０は、電力系統１０と特定負荷１２Ｂとの間に設置された配線系統である。また、電磁開閉器５２は、励磁コイル５２１及び接点５２２を備えている。また、停電検出部５４は、励磁コイル５４１及び接点５４２を備えている。   The electromagnetic switch 42 includes an exciting coil 421, a delay circuit 422, and contacts 423, 424, and 425. The electromagnetic switch 44 includes an exciting coil 441 and contacts 442 and 443. The distribution line 50 is a wiring system installed between the power system 10 and the specific load 12B. The electromagnetic switch 52 includes an exciting coil 521 and a contact 522. The power failure detection unit 54 includes an exciting coil 541 and a contact 542.

接点４４２は常閉であり、励磁コイル４４１が駆動されているときは遮断となり、励磁が解除されると導通する。（図４の他の接点は常開であり、励磁コイルが駆動されると導通し、励磁が解除されると遮断する。）   The contact 442 is normally closed, and is cut off when the excitation coil 441 is driven, and becomes conductive when the excitation is released. (The other contacts in FIG. 4 are normally open, and are turned on when the exciting coil is driven and shut off when the excitation is released.)

そこで、励磁コイル４２１は遅延回路４２２及び接点４４３を介して配電線５０に接続され、励磁コイル４４１は復帰ボタン４６を介して配電線５０に接続され、復帰ボタン４６には接点４２４が並列に接続されている。復帰ボタン４６は、ボタンスイッチの一例である。また、停電検出部５４は、励磁コイル５４１が配電線５０に接続されているので、電力系統１０が停電した際、その励磁が解除され、接点５４２が開き、停電状態を通信部２０の停電検出回路５６に通知する。   Therefore, the excitation coil 421 is connected to the distribution line 50 via the delay circuit 422 and the contact 443, the excitation coil 441 is connected to the distribution line 50 via the return button 46, and the contact 424 is connected to the return button 46 in parallel. Has been. The return button 46 is an example of a button switch. Further, since the power failure detection unit 54 has the excitation coil 541 connected to the distribution line 50, when the power system 10 fails, the excitation is released, the contact 542 is opened, and the power failure state is detected by the communication unit 20. The circuit 56 is notified.

この拡張分電盤８の処理について、図５を参照する。図５は拡張分電盤の処理を表すタイムチャートである。   With reference to FIG. FIG. 5 is a time chart showing processing of the extended distribution board.

図５において、Ａは電力系統１０の給電状態、Ｂは電磁開閉器４２の動作、Ｃは電磁開閉器４４の動作、Ｄは電磁開閉器５２の動作、Ｅは停電検出部５４の動作、ＦはＨＥＶ１６の動作を示している。   In FIG. 5, A is the power supply state of the power system 10, B is the operation of the electromagnetic switch 42, C is the operation of the electromagnetic switch 44, D is the operation of the electromagnetic switch 52, E is the operation of the power failure detection unit 54, F Indicates the operation of the HEV 16.

図５において、Ａ1 、Ｃ1 、Ｄ1 、Ｅ1 は瞬停動作、ｔ1 は停電時点、ｔ2 は停電検出及び通知時点、ｔ3 は電力系統１０の遮断時点、ｔ4 はＨＥＶ１６の放電開始時点、ｔ5 は電力系統１０の復旧時点、ｔ6 は復帰ボタン４６の操作時点、ｔ7 は電磁開閉器４４の接点４４２の遮断及びＨＥＶ１６の遮断時点、ｔ8 は電磁開閉器４２の接点４２３の導通時点、ｔ9 は電磁開閉器５２の接点５２２の導通時点、ｔ9 ’は停電検出部５４の接点５４２の導通時点、ｔ10は復旧通知時点、ｔ11はＨＥＶ１６の放電停止時点である。 In FIG. 5, A 1 , C 1 , D 1 , E 1 are instantaneous power interruption operations, t 1 is a power failure time, t 2 is a power failure detection and notification time, t 3 is a power system 10 shut-off time, and t 4 is HEV 16. discharge start point, t 5 the recovery time of the power system 10, t 6 the operation time of the wake-up button 46, t 7 is interrupted when the cut-off and HEV16 contacts 442 of the electromagnetic switch 44, t 8 is the electromagnetic switch 42 conduction time, conduction time, t 9 'is conducting when the contacts 542 of the power failure detection unit 54, t 10 recovering notification time, the discharge stop time of t 11 is HEV16 of t 9 is electromagnetic switch 52 of the contacts 522 of the contact 423 It is.

このように電磁開閉器４２はオフディレイ機能を備えているので、電力系統１０の瞬停の影響はない。   Thus, since the electromagnetic switch 42 has an off-delay function, there is no influence of the instantaneous power failure of the power system 10.

時点ｔ1 からオフディレイ時間の経過した時点ｔ3 で接点４２３が開き、電力系統１０と配電線５０とが遮断となり、復帰ボタン４６の操作時点ｔ6 の後、時点ｔ8 で接点４２３が閉じ、さらに時点ｔ9 で接点５２２が閉じて、系統復帰となる。 The contact 423 opens at the time t 3 when the off-delay time has elapsed from the time t 1 , the power system 10 and the distribution line 50 are disconnected, and the contact 423 closes at the time t 8 after the operation time t 6 of the return button 46. , contact 522 is closed at the further time point t 9, the system returns.

時点ｔ1 で停電状態となると、電磁開閉器４４の接点４４２が瞬時に導通し、復帰ボタン４６が押下される時点ｔ6 の後、時点ｔ7 まで導通状態となる。即ち、ＨＥＶ１６が特定負荷１２Ｂに給電可能状態となる。 When a power failure occurs at time t 1 , the contact 442 of the electromagnetic switch 44 is turned on instantaneously, and after time t 6 when the return button 46 is pressed, the contact is made until time t 7 . In other words, the HEV 16 can supply power to the specific load 12B.

この場合、電磁開閉器５２は時点ｔ1 直後から系統復帰後復帰ボタン４６が押された後ｔ9 まで接点５２２が開状態となる。 In this case, the electromagnetic switch 52 contacts 522 immediately after time point t 1 to t 9 after system recovery after the return button 46 is pressed the open state.

そして、停電状態が停電検出部５４で検出されると、接点５４２が開き、通信部２０から停電が通信部２２に通知される。この通知に基づき、蓄電池１８の放電による電力が特定負荷１２Ｂに供給される。この放電は停電通知後の時点ｔ4 から復旧通知後の時点ｔ11まで継続する。 When the power failure state is detected by the power failure detection unit 54, the contact 542 is opened, and the communication unit 20 notifies the communication unit 22 of the power failure. Based on this notification, the electric power from the discharge of the storage battery 18 is supplied to the specific load 12B. This discharge continues from the time t 4 after a power failure notification to the time t 11 after the recovery notification.

従って、電力系統１０の瞬停の影響を受けることなく、停電の後、復旧するまでの間、分散型負荷であるＨＥＶ１６の蓄電池１８の放電により、家屋４内の特定負荷１２Ｂへの給電が得られ、停電による不都合を回避できる。   Therefore, the power supply to the specific load 12B in the house 4 is obtained by the discharge of the storage battery 18 of the HEV 16, which is a distributed load, until the power system 10 is recovered after a power failure without being affected by the instantaneous power failure of the power system 10. Inconvenience due to power failure can be avoided.

Further, the contact 443 is cut off when the excitation coil 441 is driven and becomes conductive when the excitation is released. (The other contacts in FIG. 6 are turned on when the exciting coil is driven and cut off when the excitation is released.)

この拡張分電盤８の動作について、図７を参照する。図７は拡張分電盤の処理を表すタイムチャートである。   The operation of the extended distribution board 8 will be described with reference to FIG. FIG. 7 is a time chart showing processing of the extended distribution board.

図７のＡは電力系統１０の給電状態、図７のＢは電磁開閉器４２の動作、図７のＣは電磁開閉器５２の動作、図７のＤは電磁開閉器４４の動作、図７のＥは停電検出部５４の動作、図７のＦはＨＥＶ１６の動作を示している。   7A shows the power supply state of the power system 10, FIG. 7B shows the operation of the electromagnetic switch 42, FIG. 7C shows the operation of the electromagnetic switch 52, FIG. 7D shows the operation of the electromagnetic switch 44, FIG. E in FIG. 7 indicates the operation of the power failure detection unit 54, and F in FIG. 7 indicates the operation of the HEV 16.

図７において、Ａ1 、Ｃ1 、Ｅ1 は瞬停動作、ｔ1 は停電時点、ｔ2 は停電検出及び通知時点、ｔ3 は電力系統１０の遮断時点、ｔ4 はＨＥＶ１６の放電開始及び接続時点、ｔ5 は電力系統１０の復旧時点、ｔ6 は復帰ボタン４６の操作時点、ｔ7 は電磁開閉器４２の接点４２３の導通及び接点４２４の遮断時点、ｔ8 は電磁開閉器４４の接点４４２の遮断時点、接点４４３の導通時点、ｔ8 ’は停電検出部５４の接点５４２の導通時点、ｔ9 は電磁開閉器５２の接点５２２の導通時点、ｔ10は復旧通知時点、ｔ11はＨＥＶ１６の放電停止時点である。 In FIG. 7, A 1 , C 1 , E 1 are instantaneous power interruption operations, t 1 is a power failure time point, t 2 is a power failure detection and notification time point, t 3 is a power system 10 cutoff time point, t 4 is a HEV 16 discharge start time and At the time of connection, t 5 is the time of restoration of the power system 10, t 6 is the time of operation of the return button 46, t 7 is the time of contact 423 conduction and contact 424 of the electromagnetic switch 42, and t 8 is the time of the electromagnetic switch 44.

Power can be supplied to the load 12B, and inconvenience due to a power failure can be avoided.

〔第５の実施の形態〕 [Fifth Embodiment]

第５の実施の形態は、停電復旧時に自動的に電力系統１０からの給電を復旧し、また電磁開閉器に停電検出部を兼用させる等、簡略化した拡張分電盤の構成を示している。   The fifth embodiment shows a simplified configuration of an extended distribution board that automatically restores power supply from the power system 10 when a power failure is restored, and also uses an electromagnetic switch as a power failure detection unit. .

この第５の実施の形態について図８を参照する。図８は、第５の実施の形態に係る拡張分電盤を示している。図８において、図４又は図６と同一部分には同一符号を付してある。   The fifth embodiment will be described with reference to FIG. FIG. 8 shows an extended distribution board according to the fifth embodiment. In FIG. 8, the same parts as those in FIG. 4 or FIG.

この実施の形態の拡張分電盤８では、電磁開閉器４２に既述の停電検出部５４（図４、図６）を兼用させるとともに、電磁開閉器４４に電磁開閉器５２を合体させ、自動復帰ボタン４６（図４、図６）を省略した構成である。   In the extended distribution board 8 of this embodiment, the electromagnetic switch 42 is also used as the power failure detection unit 54 (FIGS. 4 and 6) described above, and the electromagnetic switch 52 is combined with the electromagnetic switch 44 to automatically The return button 46 (FIGS. 4 and 6) is omitted.

そこで、電磁開閉器４２は、励磁コイル４２１、遅延回路４２２、接点（常開）４２３、接点（常開）４２４を備えている。接点４２４は、既述の停電検出部５４の一例であって、既述の接点（常開）５４２（図４、図６）に対応する。接点４２４には通信部２０の停電検出回路５６が接続されている。   Therefore, the electromagnetic switch 42 includes an exciting coil 421, a delay circuit 422, a contact (normally open) 423, and a contact (normally open) 424. The contact point 424 is an example of the power failure detection unit 54 described above, and corresponds to the contact point (normally open) 542 (FIGS. 4 and 6). A power failure detection circuit 56 of the communication unit 20 is connected to the contact 424.

この拡張分電盤８の処理について、図９を参照する。図９は拡張分電盤の処理手順の一例を示している。   The processing of the extended distribution board 8 will be described with reference to FIG. FIG. 9 shows an example of the processing procedure of the extended distribution board.

この処理手順は、本発明の分電方法の一例であって、図９に示すように、数秒間の瞬間停電を超える一定時間以上の停電が発生すると（ステップＳ２１）、電磁開閉器４２がＯＦＦ（電力系統１０の遮断）、電磁開閉器４４がＯＦＦ（ＨＥＶ１６の接続）となる（ステップＳ２２）。   This processing procedure is an example of the power distribution method of the present invention. As shown in FIG. 9, when a power failure occurs for a certain time exceeding a momentary power failure for several seconds (step S21), the electromagnetic switch 42 is turned off. (Interruption of the electric power system 10), the electromagnetic switch 44 is turned off (connection of HEV 16) (step S22).

電磁開閉器４２のＯＦＦを検知し、通信部２０により停電発生を無線通信でＨＥＶ１６に通知する（ステップＳ２３）。ＨＥＶ１６の電力が供給され、特定負荷１２Ｂが稼働する（ステップＳ２４）。   The OFF of the electromagnetic switch 42 is detected, and the occurrence of a power failure is notified to the HEV 16 by wireless communication by the communication unit 20 (step S23). The power of the HEV 16 is supplied and the specific load 12B is operated (step S24).

電力系統１０が停電から復帰したかを監視し（ステップＳ２５）、復帰した場合には、電磁開閉器４４がＯＮ（ＨＥＶ１６の遮断）、電磁開閉器４２がＯＮ（電力系統１０の復帰）となり（ステップＳ２６）、電力系統１０からの給電が行われる。そして、電磁開閉器４２のＯＮを検知し、停電終了を無線通信でＨＥＶ１６に通知し（ステップＳ２７）、ステップＳ２１に戻る。   Whether or not the power system 10 has recovered from a power failure is monitored (step S25). When the power system 10 recovers, the electromagnetic switch 44 is turned on (HEV 16 is shut off) and the electromagnetic switch 42 is turned on (return of the power system 10) ( Step S26), power supply from the power system 10 is performed. Then, ON of the electromagnetic switch 42 is detected, the end of the power failure is notified to the HEV 16 by wireless communication (step S27), and the process returns to step S21.

この拡張分電盤８の動作について、図１０を参照する。図１０は拡張分電盤の処理を表すタイムチャートである。   The operation of the expansion distribution board 8 will be described with reference to FIG. FIG. 10 is a time chart showing processing of the extended distribution board.

図１０のＡは電力系統１０の給電状態、図１０のＢは電磁開閉器４２の動作、図１０のＣは電磁開閉器４４の動作、図１０のＤはＨＥＶ１６の動作を示している。   10A shows the power supply state of the power system 10, FIG. 10B shows the operation of the electromagnetic switch 42, FIG. 10C shows the operation of the electromagnetic switch 44, and FIG. 10D shows the operation of the HEV 16.

図１０において、Ａ1 は瞬停動作、ｔ1 は停電時点、ｔ2 は電力系統１０の遮断時点、ｔ3 は停電検出及び通知時点、ｔ4 はＨＥＶ１６の接続時点、ｔ5 はＨＥＶ１６からの給電開始（放電）時点、ｔ6 は電力系統１０の復旧時点、ｔ7 はＨＥＶ１６の遮断時点、ｔ8 は系統復帰時点、ｔ9 は復旧通知時点、ｔ10はＨＥＶ１６の放電停止時点である。 In FIG. 10, A 1 is an instantaneous power failure operation, t 1 is a power failure time, t 2 is a power system 10 disconnection time, t 3 is a power failure detection and notification time, t 4 is a HEV 16 connection time, and t 5 is from HEV 16. When power supply is started (discharged), t 6 is the time when the power system 10 is restored, t 7 is the time when the HEV 16 is shut off, t 8 is the time when the system is restored, t 9 is the time when the recovery is notified, and t 10 is the time when the HEV 16 stops discharging.

この拡張分電盤８では、電磁開閉器４２、４４は遅延回路４２２、４４４により電源オフディレイ機能を備えている。Ｔｄａは電磁開閉器４２の遅延時間、Ｔｄｂは電磁開閉器４４の遅延時間とし、Ｔｄａ＜Ｔｄｂに設定されている。   In the extended distribution board 8, the electromagnetic switches 42 and 44 have a power-off delay function by delay circuits 422 and 444. Tda is the delay time of the electromagnetic switch 42, Tdb is the delay time of the electromagnetic switch 44, and Tda <Tdb is set.

そこで、瞬停時には電源オフディレイ機能により、Ｔｄａ未満の瞬停であれば、電磁開閉器４２、４４はオフしない。停電時には、停電後Ｔｄａが経過すると電磁開閉器４２がオフし、停電後Ｔｄｂ経過すると電磁開閉器４４がオフする。ここで Ｔｄａ＜Ｔｄｂであるから、電磁開閉器４２→電磁開閉器４４の順でオフし、特定負荷１２Ｂ側にＨＥＶ１６が接続される。電磁開閉器４２がオフすると、通信によりＨＥＶ１６に停電通知を行い、ＨＥＶ１６では放電を開始する。   Therefore, at the momentary power failure, the electromagnetic switches 42 and 44 are not turned off by a power-off delay function if the power failure is less than Tda. At the time of a power failure, the electromagnetic switch 42 is turned off when Tda elapses after the power failure, and the electromagnetic switch 44 is turned off when Tdb elapses after the power failure. Here, since Tda <Tdb, the electromagnetic switch 42 is turned off in the order of the electromagnetic switch 44, and the HEV 16 is connected to the specific load 12B side. When the electromagnetic switch 42 is turned off, a power failure notification is sent to the HEV 16 by communication, and the HEV 16 starts discharging.

また、復旧時には、系統復旧により電磁開閉器４４がオンすることによりＨＥＶ１６が遮断され、またこれにより電磁開閉器４２が駆動し、電磁開閉器４２がオンするので、電磁開閉器４４→電磁開閉器４２の順でオンし、特定負荷１２Ｂ側には電力系統１０が接続される。   Further, at the time of restoration, the HEV 16 is cut off by turning on the electromagnetic switch 44 due to system restoration, and this causes the electromagnetic switch 42 to be driven and the electromagnetic switch 42 to be turned on. Therefore, the electromagnetic switch 44 → the electromagnetic switch The power system 10 is connected to the specific load 12B side.

そして、電磁開閉器４２がオンすると、通信によりＨＥＶ１６に復旧通知を行い、ＨＥＶ１６は放電を停止し、ＨＥＶ１６から拡張分電盤８への給電を停止する。   When the electromagnetic switch 42 is turned on, the recovery notification is sent to the HEV 16 by communication, the HEV 16 stops discharging, and power supply from the HEV 16 to the extended distribution board 8 is stopped.

このように、第５の実施の形態においても、電力系統１０の瞬停の影響を受けることなく、停電の後、復旧するまでの間、分散型負荷であるＨＥＶ１６の蓄電池１８の放電により、家屋４内の特定負荷１２Ｂへの給電が得られ、停電による不都合を回避できる。   As described above, in the fifth embodiment as well, due to the discharge of the storage battery 18 of the HEV 16, which is a distributed load, after the power failure and without being affected by the instantaneous power failure of the power system 10, Power supply to the specific load 12B in 4 is obtained, and inconvenience due to a power failure can be avoided.

〔上記実施の形態の特徴事項及び他の実施の形態〕 [Characteristics of the above embodiment and other embodiments]

(1) 停電時に電力系統１０を切り離してから分散型電源を接続することができ、分散型電源による給電とともに、分散型電源を用いることによる電力系統１０への影響を回避できる。上記実施の形態に記載した通り、第２の実施の形態では、分岐ブレーカ１０を介在し、第３及び第４の実施の形態では、分岐ブレーカ４０に加え、電磁開閉器４２、５２（図４、図６）を介在したことにより、電力系統１０に対して分散型電源が直結されることがなく、電力系統１０に対する安全性を維持することができる。   (1) A distributed power source can be connected after the power system 10 is disconnected at the time of a power failure, and the influence on the power system 10 due to the use of the distributed power source can be avoided together with the power supply by the distributed power source. As described in the above embodiment, in the second embodiment, the branch breaker 10 is interposed, and in the third and fourth embodiments, in addition to the branch breaker 40, the electromagnetic switches 42 and 52 (FIG. 4). 6), the distributed power source is not directly connected to the power system 10, and the safety of the power system 10 can be maintained.

(2) 停電発生や復旧を拡張分電盤８からＨＥＶ１６に通知し、電力系統１０とＨＥＶ１６との接続、その接続遮断の信頼性を高めている。しかも、通信部２０には電力系統１０と完全に独立した電池６４を電源に用いているので、通信部２０の動作が電力系統１０と独立させることができ、動作の信頼性を確保している。この電池６４が消耗したことによる動作不良が生じた場合でも、第３及び第４の実施の形態ではＨＥＶ１６が遮断されたあとで電力系統１０が復帰するため、不都合を生じることはない。   (2) The occurrence of power failure or recovery is notified from the extension distribution board 8 to the HEV 16, and the reliability of the connection between the power system 10 and the HEV 16 and the disconnection thereof is improved.

Even if a malfunction occurs due to the consumption of the battery 64, the power system 10 is restored after the HEV 16 is shut off in the third and fourth embodiments, so that no inconvenience occurs.

(3) 拡張分電盤８は既設の住宅用分電盤６と分離独立しているので、分散型電源を使用する場合には、拡張分電盤８の増設のみで停電対策システム２（図１）を実現することができる。   (3) Since the expansion distribution board 8 is separated and independent from the existing residential distribution board 6, when using a distributed power source, the power distribution countermeasure system 2 (see Fig. 1) can be realized.

(4) 上記実施の形態では、家屋４に拡張分電盤８を常設する形態で説明したが、この拡張分電盤８を家屋４に着脱可能な分電装置として構成し、必要に応じて住宅用分電盤６に着脱し、停電時、特定負荷１２Ｂに給電する構成としてもよい。   (4) In the above embodiment, the explanation has been made in the form in which the extension distribution board 8 is permanently installed in the house 4. However, the extension distribution board 8 is configured as a power distribution device that can be attached to and detached from the house 4, and as necessary. It is good also as a structure which attaches and detaches to the distribution board 6 for houses, and supplies electric power to the specific load 12B at the time of a power failure.

(5) 分散型電源としてＨＥＶ１６の蓄電池１８を例示したが、蓄電池１８とＤＣ−ＡＣコンバータを備えた補助電源を用いてもよい。また、ＤＣ−ＡＣコンバータを家屋４に設置することも可能であり、この場合、分散型電源は蓄電池１８のみの構成でもよい。   (5) Although the storage battery 18 of the HEV 16 is illustrated as the distributed power source, an auxiliary power source including the storage battery 18 and a DC-AC converter may be used. Moreover, it is also possible to install a DC-AC converter in the house 4, and in this case, the distributed power source may be configured by only the storage battery 18.

(6) 上記実施の形態では、電力系統１０に商用交流電源を例示したが、自家発電装置であってもよい。   (6) In the above embodiment, the commercial AC power source is exemplified for the power system 10, but a private power generation device may be used.

(7) 第１の実施の形態では、拡張分電盤８を家屋４の外壁に設置しているが、家屋４内に設置してもよい。   (7) In the first embodiment, the expansion distribution board 8 is installed on the outer wall of the house 4, but it may be installed in the house 4.

(8) 上記実施の形態では、通信部２０、２２間の通信を無線で行っているが、有線であってもよく、無線の場合、通信媒体は電波、音波（超音波）でもよく、電波の場合、可視光や赤外線を用いてもよい。通信確立のためのプロトコルは既存のものを用いればよい。有線の場合、充放電コンセント１４と接続する充電プラグ３２を介在する給電線搬送を用いてもよい。   (8) In the above embodiment, communication between the communication units 20 and 22 is performed wirelessly, but may be wired, and in the case of wireless, the communication medium may be radio waves or sound waves (ultrasonic waves). In this case, visible light or infrared light may be used. An existing protocol may be used for establishing communication. In the case of a wired connection, feeding line conveyance with a charging plug 32 connected to the charging / discharging outlet 14 may be used.

(9) 上記実施の形態では、ＨＥＶ１６に搭載されたコンバータ２６がＤＣ−ＡＣコンバータ、ＡＣ−ＤＣコンバータの双方の機能を備えているが、コンバータ２６に代え、それぞれのコンバータを備えてもよい。この場合、充放電コンセント１４及び充放電プラグ３２を充放電共用型としているが、充電用及び放電用を別個に構成してもよい。また、コンバータ２６の全部又は一部を、ＨＥＶ１６の外部に設けるようにしてもよい。   (9) In the above embodiment, the converter 26 mounted on the HEV 16 has functions of both a DC-AC converter and an AC-DC converter, but each converter may be provided instead of the converter 26. In this case, the charging / discharging outlet 14 and the charging / discharging plug 32 are of a charge / discharge shared type, but charging and discharging may be configured separately.
