Consequently, the load factor is enhanced while always managing the maximum electric consumption on the load side not to exceed a set reference power, and cut-off of supply power, i.e., power interruption as well as overload is prevented while reducing cost due to power consumption.

Description

本発明は、過負荷と供給電力遮断防止技術に関し、詳しくは、消費電力が少ない場合には予備電力を充電し、消費電力が供給電力を超える場合には消費電力のピーク値から充電の予備電力を使用することで、消費電力の過負荷を防止することができるとともに、過負荷による供給電力の遮断（断電）を防止することができる過負荷と供給電力遮断防止装置及び方法（Prevention device of the shut off overload and supply power and method thereof）に関する。   The present invention relates to an overload and supply power cut-off prevention technology, and more specifically, reserve power is charged when power consumption is low, and reserve power is charged from a peak value of power consumption when power consumption exceeds supply power. Overload and supply power cut-off prevention device and method (Prevention device of) capable of preventing overload of power consumption and preventing cut-off of supply power due to overload the shut off overload and supply power and method thereof).

一般に、夏冬の季節には冷暖房使用が増えるため電力需要が多くなるが、このように増大する電力需要量に対応するために発電設備を備えなければならない。   In general, the use of air conditioning increases during the summer and winter seasons, increasing the power demand. However, it is necessary to provide power generation facilities in order to cope with the increasing power demand.

しかし、追加的に発展設備を新設することになると費用負担、敷地確保、そして環境汚染及び地域住民の反発など相当な問題点を抱えることになり、そのために新規発電設備を設置することができなく、韓電電力の供給電力が消費電力を収容できなくなる場合がたびたび発生する。特に、電力供給が中断される場合が発生し、営業場や産業施設では営業や製品生産が中断されるという問題点が発生される。   However, if additional development facilities are newly installed, there will be considerable problems such as cost burden, securing of the site, environmental pollution and repulsion of local residents, and it is therefore impossible to install new power generation facilities. In many cases, the power supplied by KEPCO cannot accommodate the power consumption. In particular, there is a case where power supply is interrupted, and there is a problem that sales and product production are interrupted in a business office or an industrial facility.

そこで、比較的に大規模の産業界では、自家発電設備を設けることで自家発電による供給電力の遮断に備えているが、このような自家発電設備は断電に対処するための設備であって、断電を予防するものはできない。特に、零細営業場や産業施設では、このような自家発電設備による費用負担で自家発電設備を設けることができなく、電力供給が中断された場合、そのまま被害を受けるしかなかった。   Therefore, in a relatively large-scale industry, a private power generation facility is provided to cut off the power supplied by the private power generation. However, such a private power generation facility is a device for coping with power interruption. There is nothing that can prevent power interruption. In particular, in small business offices and industrial facilities, private power generation equipment cannot be provided at the expense of such private power generation equipment, and if power supply is interrupted, it has only been damaged.

The inverter 33 is configured to convert the reserve power charged in the storage battery 32 into a converted output (DC → AC) and then supply it to the load 200 side as necessary. Yes.

前記第２開閉部４０は前記予備電力充電部３０と前記負荷２００側の電源ラインとに接続されるもので、前記予備電力充電部３０に充電された予備電力を負荷２００側に供給または遮断できるようにオフ／オン動作し、前記オフ／オン動作は前記電力制御部５０の制御によって行われる。   The second opening / closing unit 40 is connected to the reserve power charging unit 30 and the power line on the load 200 side, and can supply or block the reserve power charged in the reserve power charging unit 30 to the load 200 side. The off / on operation is performed under the control of the power control unit 50.

このとき、前記第２開閉部４０は、図４に示すように、Ａ、Ｂ区間を除いた区間のように電力消費量が設定された基準消費電力よりも小さいか同一である場合には前記電力制御部５０の制御動作によりオフ動作し、図４のＡ、Ｂ区間のように電力消費量が設定された基準消費電力よりも大きいか、または電力供給先１００から電力供給が遮断（断電）される場合には、前記電力供給先１００から負荷２００に供給される電力が基準消費電力よりも小さくなるように前記電力制御部５０の制御動作によりオン動作して前記予備電力充電部３０の蓄電池３２に充電されるよび電力を負荷２００側に供給するように構成される。   At this time, as shown in FIG. 4, when the second opening / closing unit 40 is smaller than or equal to the set reference power consumption as in the sections excluding the A and B sections, The operation is turned off by the control operation of the power control unit 50, and the power consumption is larger than the set reference power consumption as in the sections A and B of FIG. ), The power supplied from the power supply destination 100 to the load 200 is turned on by the control operation of the power control unit 50 so that the power supplied to the load 200 is smaller than the reference power consumption. The storage battery 32 is charged and power is supplied to the load 200 side.

前記電力制御部５０は、使用者が任意に指定する基準消費電力が設定されて保存され、前記設定された基準消費電力と前記計量部１０からチェックされる電力消費量とを比較して前記電力供給先１００から供給される電力を負荷２００側に供給するか、または前記予備電力充電部３０に充電される予備電力を負荷２００側に供給するように前記第１開閉部２０のオン／オフ動作はもちろん、前記第２開閉部４０のオフ／オン動作を選択的に制御するものであって、前記基準消費電力は時間当たりの平均電力に設定するか、または使用者により設定される任意設定電力である。   The power control unit 50 sets and stores a reference power consumption arbitrarily designated by a user, compares the set reference power consumption with a power consumption checked by the weighing unit 10, and compares the power consumption. ON / OFF operation of the first opening / closing unit 20 so that the power supplied from the supply destination 100 is supplied to the load 200 side or the standby power charged in the backup power charging unit 30 is supplied to the load 200 side Of course, it selectively controls the off / on operation of the second opening / closing part 40, and the reference power consumption is set to an average power per time or an arbitrarily set power set by the user. It is.

このように構成された本発明の実施形態による作用を図１ないし図４を参照して説明すると、まずは家庭や産業現場で使用者がすべての負荷側に対する基準消費電力、すなわち時間当たりの平均電力または任意設定電力を設定した後に、これを電力制御部５０に保存する。   The operation of the embodiment of the present invention configured as described above will be described with reference to FIGS. 1 to 4. First, the user uses the reference power consumption for all loads at home or industrial site, that is, average power per hour. Alternatively, after setting the arbitrarily set power, it is stored in the power control unit 50.

次に、上記のように基準消費電力を設定して保存した状態において、電力供給先１００から電力が供給されると、供給された電力は負荷２００に供給される。   Next, when power is supplied from the power supply destination 100 in a state where the reference power consumption is set and stored as described above, the supplied power is supplied to the load 200.

このとき、計量部１０は前記電力供給先１００から負荷２００に供給される電力を感知した後、これを電力制御部５０に提供することになり，前記電力制御部５０は前記計量部１０を介して負荷２００に供給されて消費される電力消費量が基準消費電力より小さいか同一である場合、第１開閉部２０にオン動作する一方，第２開閉部４０をオフ動作させながら予備電力充電部３０に予備電力として充電する。   At this time, the metering unit 10 senses the power supplied from the power supply destination 100 to the load 200, and then provides the power to the power control unit 50. The power control unit 50 passes the metering unit 10 through the metering unit 10. When the power consumption consumed and supplied to the load 200 is smaller than or equal to the reference power consumption, the standby power charging unit is turned on while the second opening / closing unit 40 is turned off while the first opening / closing unit 20 is turned on. 30 is charged as reserve power.

すなわち、前記予備電力充電部３０に含まれる整流器３１は負荷２００側の電源ラインとに接続されるので、前記整流器３１は前記第１開閉部２０のオン動作時に前記負荷２００側に流れる電力を整流（ＡＣ→ＤＣ）した後、これを蓄電池３２に供給することで、前記蓄電池３２は前記整流器３１から整流された電力を予備電力として充電することができる。   That is, since the rectifier 31 included in the standby power charging unit 30 is connected to the power line on the load 200 side, the rectifier 31 rectifies the power flowing to the load 200 side when the first opening / closing unit 20 is turned on. After (AC → DC), by supplying this to the storage battery 32, the storage battery 32 can be charged with the power rectified from the rectifier 31 as reserve power.

そこで、前記負荷２００の時間当たりの電力消費量は計量部１０によって感知された後、電力制御部５０に伝達されるので、前記電力制御部５０は前記計量部１０により感知された時間当たりの電力消費量と前記設定されて保存された基準消費電力とを比較することができる。   Therefore, the power consumption per hour of the load 200 is sensed by the metering unit 10 and then transmitted to the power control unit 50, so that the power control unit 50 senses the power per hour sensed by the metering unit 10. The consumption amount can be compared with the set and stored reference power consumption.

しかし、前記時間当たりの電力消費量が基準消費電力よりも大きい場合、前記電力制御部５０は前記電力供給先１００から負荷２００に供給される電力が基準消費電力よりも小さくなるように、前記第１開閉部２０をオフ動作させ、前記予備電力充電部３０の蓄電池３２に予備電力が充電されることを遮断するとともに、前記蓄電池３２に充電される予備電力を負荷２００に供給できるように前記第２開閉部４０をオン動作する制御動作を行うことになる。   However, when the power consumption per time is larger than the reference power consumption, the power control unit 50 causes the power control unit 50 to reduce the power supplied from the power supply destination 100 to the load 200 so as to be smaller than the reference power consumption. The first opening / closing unit 20 is turned off to block the storage battery 32 of the backup power charging unit 30 from being charged with backup power, and the backup power charged to the battery 32 can be supplied to the load 200. The control operation for turning on the 2 opening / closing unit 40 is performed.

すなわち、前記電力制御部５０は、図４に示すように、Ａ、Ｂ区間を除いた区間のように、電力消費量が設定された基準消費電力よりも小さいか、または同一である場合、第１開閉部２０をオン動作させ、前記第２開閉部４０をオフ動作させ、前記電力供給先１００による電力が蓄電池３２に充電できるようにする。   That is, as shown in FIG. 4, when the power consumption is smaller than or equal to the set reference power consumption, as shown in FIG. The first opening / closing part 20 is turned on, and the second opening / closing part 40 is turned off, so that the storage battery 32 can be charged with electric power from the power supply destination 100.

一方、図４に示すように、Ａ、Ｂ区間のように電力消費量が設定された基準消費電力よりも大きい場合、前記電力制御部５０は前記第１開閉部２０をオフ動作させながら第２開閉部４０はオン動作させて前記電力供給先１００から負荷２００に供給される電力が基準消費電力よりも小さくなるように、前記電力供給先１００から負荷２００に供給される電力と並列に前記蓄電池３２に充電される予備電力をインバータ３３を介して負荷２００側に供給させることになる。   On the other hand, as shown in FIG. 4, when the power consumption is larger than the set reference power consumption as in the A and B sections, the power control unit 50 performs the second operation while turning off the first opening / closing unit 20. The storage battery is connected in parallel with the power supplied from the power supply destination 100 to the load 200 such that the power supplied from the power supply destination 100 to the load 200 is smaller than the reference power consumption by turning on the opening / closing unit 40. The reserve power charged to 32 is supplied to the load 200 side via the inverter 33.

一方、前記電力供給先１００から電力供給が遮断（断電）される場合、前記電力制御部５０は、第２開閉部４０をオン動作させる制御動作を行うことができ、これによって前記蓄電池３２に保存された予備電力はインバータ３３を介して非常電力として、それぞれ前記負荷２００に供給され、断電から来る不便さを改善することができる。   On the other hand, when the power supply from the power supply destination 100 is interrupted (disconnected), the power control unit 50 can perform a control operation to turn on the second opening / closing unit 40, thereby causing the storage battery 32 to The stored standby power is supplied to the load 200 as emergency power through the inverter 33, so that inconvenience due to power interruption can be improved.
