上述した本発明の目的、特徴及び長所は、添付の図面と関連した次の実施例を通じてより明らかになる。 The above-described objects, features, and advantages of the present invention will become more apparent through the following embodiments in conjunction with the accompanying drawings.
以下の特定の構造乃至機能的な説明は、単に本発明の概念による実施例を説明するための目的で例示されたもので、本発明の概念による各実施例は多様な形態で実施可能であり、本明細書または図面において説明される実施例に限定されると解釈されてはならない。 The following specific structural or functional descriptions are merely illustrated for the purpose of illustrating the embodiments according to the concepts of the present invention, and the embodiments according to the concepts of the present invention may be implemented in various forms. And should not be construed as limited to the embodiments set forth herein or in the drawings.
以下、添付の図面を参照して本発明の好適な実施例を説明することによって、本発明を詳細に説明する。各図面に提示された同一の参照符号は同一の部材を示す。 Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the invention with reference to the accompanying drawings. The same reference numerals provided in each drawing denote the same members.
図１は、本発明の一実施例に係るリチウムポリマーバッテリーを用いた無停電電源供給装置の概略的な構成を示す説明図である。 FIG. 1 is an explanatory diagram showing a schematic configuration of an uninterruptible power supply apparatus using a lithium polymer battery according to an embodiment of the present invention.
図１を参照すると、本発明の一実施例に係るリチウムポリマーバッテリーを用いた無停電電源供給装置１００は、リチウムポリマーバッテリーを用いたバッテリーモジュール１１０、バッテリー制御部（ｂａｔｔｅｒｙ ｍａｎａｇｅｍｅｎｔ ｓｙｓｔｅｍ：ＢＭＳ)１２０、及びＤＣ／ＡＣインバータ１３０などを含んで構成されることが分かる。 Referring to FIG. 1, an uninterruptible power supply device 100 using a lithium polymer battery according to an embodiment of the present invention includes a battery module 110 using a lithium polymer battery, a battery control unit (BMS) 120, It can be seen that the configuration includes a DC / AC inverter 130 and the like.
リチウムポリマーバッテリーは、例えば、ジェルタイプの高分子（ｐｏｌｙｍｅｒ）を電解質として使用し、再充電が可能なバッテリーであってよく、陰極と陽極間の分離膜が、リチウムイオンバッテリーでの電極を分離する役割以外に、イオン伝導の媒体、すなわち電解質の役割をし得る。このようなリチウムポリマーバッテリーは、連続的な充電及び放電が可能なので、別途の電源供給なしに長時間使用できるなどの長所を有する。 The lithium polymer battery may be a rechargeable battery using, for example, a gel type polymer as an electrolyte, and a separation membrane between the cathode and the anode separates the electrodes in the lithium ion battery. In addition to its role, it can act as an ion-conducting medium, ie, an electrolyte. Since such a lithium polymer battery can be continuously charged and discharged, it has an advantage that it can be used for a long time without a separate power supply.
このようなリチウムポリマーバッテリーを用いた本発明の実施例に係る無停電電源供給装置１００は、例えば、移動通信中継器または半導体製造設備などに適用可能なように構成されることができ、通常のＡＣ電源部などを通じて正常に供給される電源はチャネル１（ＣＨ１）を介して入力され、チャネル２（ＣＨ２、ＣＨ２'）を介して正常に設備に供給される一方、一部はＤＣ／ＡＣインバータ１３０を通じて変換された後、バッテリーモジュール１１０に充電される。そして、停電などの非常状況が発生してチャネル１（ＣＨ１）を介した電源供給ができなくなる場合、前記バッテリーモジュール１１０に充電されていた電力を、ＤＣ／ＡＣインバータ１３０を通じて変換した後、チャネル２（ＣＨ２、ＣＨ２'）を介して設備に供給できるようにすることで、設備に対する安定的な電源供給ができるように機能する。このような過程において、前記バッテリーモジュール１１０の充放電とその他の全ての動作はバッテリー制御部１２０を通じて管理される。 The uninterruptible power supply apparatus 100 according to the embodiment of the present invention using such a lithium polymer battery can be configured to be applicable to, for example, a mobile communication repeater or a semiconductor manufacturing facility. The power normally supplied through the AC power supply unit or the like is input through the channel 1 (CH1) and is normally supplied to the equipment through the channel 2 (CH2, CH2 ′), while a part is a DC / AC inverter. After being converted through 130, the battery module 110 is charged. When an emergency situation such as a power failure occurs and power cannot be supplied via the channel 1 (CH1), the power charged in the battery module 110 is converted through the DC / AC inverter 130, and then the channel 2 By making it possible to supply the equipment via (CH2, CH2 ′), the power supply functions stably. In this process, charging / discharging and all other operations of the battery module 110 are managed through the battery controller 120.
すなわち、図１に示す無停電電源供給装置１００は、通常の無停電電源供給装置においてバッテリーモジュールとしてリチウムポリマーバッテリーモジュール１１０を採用し、これによって、リチウムポリマーバッテリーの動作制御のためのバッテリー制御部１２０を備えた構成を有することが分かる。 That is, the uninterruptible power supply apparatus 100 shown in FIG. 1 employs a lithium polymer battery module 110 as a battery module in a normal uninterruptible power supply apparatus, and thereby a battery control unit 120 for controlling the operation of the lithium polymer battery. It turns out that it has the structure provided with.
このとき、本発明の実施例に係る無停電電源供給装置１００に備えられるバッテリー制御部１２０は、データ通信を用いた遠隔運用が可能なようになされる。言い換えると、多数の無停電電源供給装置１００に対して、バッテリーモジュール１１０の充放電現況データなどがバッテリー制御部１２０によって伝送されると、遠隔地の管理者は前記データを全体的に把握して管理し、異常があると判断される無停電電源供給装置１００に対しては、遠隔制御を通じて措置を取ることができるようにする。 At this time, the battery control unit 120 provided in the uninterruptible power supply apparatus 100 according to the embodiment of the present invention can be remotely operated using data communication. In other words, when the charging / discharging status data of the battery module 110 is transmitted to the large number of uninterruptible power supply devices 100 by the battery control unit 120, the remote manager grasps the data as a whole. The uninterruptible power supply apparatus 100 that is managed and determined to be abnormal can be taken through remote control.
ここで、前記バッテリー制御部１２０とのデータ通信は、多様な形態の端末機を用いた有線または無線の全てのデータ通信方式が適用可能であるが、好ましくは、ＴＣＰ／ＩＰを用いたデータ通信方式を適用することが良い。この場合、無停電電源供給装置１００に搭載されたモドバス（Ｍｏｄｂｕｓ）プロトコルをＴＣＰ／ＩＰに変換するための別途のコンバータなどを備えることが有益である。 Here, for data communication with the battery control unit 120, all wired or wireless data communication methods using various types of terminals can be applied. Preferably, data communication using TCP / IP is used. It is good to apply the method. In this case, it is advantageous to provide a separate converter for converting the Modbus protocol mounted on the uninterruptible power supply apparatus 100 into TCP / IP.
ここで、本発明の一実施例に係るリチウムポリマーバッテリーを用いた無停電電源供給装置１００は、太陽光などを用いた補助電源供給部を追加で備えることができ、運用コストの節減などのために、時間による運用モードの設定が可能なだけでなく、過電流、漏電または短絡などにより電源遮断器が作動する場合にも、管理者が直接訪問して操作することなく設備の原状回復が可能なようにする等の多様な機能を具備することができる。以上の機能及び構成については、以下の図面を用いてより詳細に説明する。 Here, the uninterruptible power supply apparatus 100 using the lithium polymer battery according to an embodiment of the present invention can additionally include an auxiliary power supply unit using sunlight, etc. In addition, it is possible not only to set the operation mode according to time, but also to restore the equipment to its original state without a direct visit by the administrator when the power breaker is activated due to overcurrent, leakage or short circuit. It can be provided with various functions such as The above functions and configurations will be described in more detail with reference to the following drawings.
図１において説明されていないアップ／ダウンブースト（ＵＰ／ＤＯＷＮ ＢＯＯＳＴ）回路は、通常の無停電電源供給装置のようにトランスフォーマーなどを用いて具現することができる。なお、図面に別途に示していないが、バッテリーモジュールなどの状態をリアルタイムで表出するためのＬＥＤディスプレイ窓などが追加で備えられてもよい。 An up / down boost (UP / DOWN BOOST) circuit which is not described in FIG. 1 can be implemented using a transformer or the like as in a normal uninterruptible power supply. Although not separately shown in the drawing, an LED display window or the like for displaying the state of the battery module or the like in real time may be additionally provided.
図２は、本発明の実施例に係る無停電電源供給装置の電源供給系統を概略的に示した説明図であって、図２に示された無停電電源供給装置２００は、通常のＡＣ電源供給部２２０以外に太陽電池などを用いた追加的な電源供給部２１０を備えていることが分かる。 FIG. 2 is an explanatory diagram schematically showing a power supply system of an uninterruptible power supply apparatus according to an embodiment of the present invention. The uninterruptible power supply apparatus 200 shown in FIG. It can be seen that an additional power supply unit 210 using a solar cell or the like is provided in addition to the supply unit 220.
すなわち、無停電電源供給装置２００に対する安定的な電源供給及び維持コストの節減などのために、太陽電池を用いた太陽光電源供給部２１０などを追加で備えることができ、この場合、太陽光電源供給部２１０を通じた正常な電源供給が可能な場合には、これを通じて電源が供給され、天気などの影響により正常な太陽電池の作動が難しい状況には、通常のＡＣ電源供給部２２０を通じて電源が供給される構成を示す。 That is, in order to stably supply power to the uninterruptible power supply apparatus 200 and reduce maintenance costs, a solar power supply unit 210 using solar cells can be additionally provided. When normal power supply through the supply unit 210 is possible, power is supplied through the supply unit 210. When the normal solar cell is difficult to operate due to the influence of weather or the like, power is supplied through the normal AC power supply unit 220. The structure supplied is shown.
そのために、図２に示すように、両方向インバータ２４０が採用されることによって、多数の電源供給部２１０、２２０とバッテリーモジュール２３０及び充電回路２５０間の選択的な連結が可能なように機能することを確認することができる。 For this purpose, as shown in FIG. 2, the bidirectional inverter 240 is employed to function so that the multiple power supply units 210 and 220 and the battery module 230 and the charging circuit 250 can be selectively connected. Can be confirmed.
このとき、太陽光電源供給部２１０には、通常のいかなる方式の太陽光を用いた電気発生技術も適用可能であり、図示していないが、例えば、風力を用いた電源供給などの技術にも代替可能である。 At this time, the solar power supply unit 210 can be applied with any ordinary method of generating electricity using sunlight, and is not shown in the figure. It can be substituted.
なお、図面とは異なり、ＡＣ電源供給部２２０との兼用使用なしに、太陽光電源供給部２１０単独からなる電源供給部の構成もまた可能である。 Note that, unlike the drawing, a configuration of a power supply unit including the solar power supply unit 210 alone is also possible without using the AC power supply unit 220 together.
ここで、前記バッテリーモジュール２３０はリチウムポリマーバッテリーからなり、前記バッテリーモジュール２３０及び充電回路２５０はバッテリー制御部（図示せず）により制御される構成を有する。 Here, the battery module 230 includes a lithium polymer battery, and the battery module 230 and the charging circuit 250 are controlled by a battery control unit (not shown).
図３は、本発明の実施例に係る無停電電源供給装置の運用状態を説明するための例示図である。 FIG. 3 is an exemplary diagram for explaining an operation state of the uninterruptible power supply apparatus according to the embodiment of the present invention.
図１及び図２に示したような本発明の実施例に係る無停電電源供給装置は、運用コストの節減及び運用効率の向上などのために、リチウムポリマー電池に対する充放電時間を設定することができる。 The uninterruptible power supply apparatus according to the embodiment of the present invention as shown in FIG. 1 and FIG. 2 can set the charge / discharge time for the lithium polymer battery in order to reduce the operation cost and improve the operation efficiency. it can.
言い換えると、電力需要が増加することにより相対的に電力料金が高い時間帯には、外部電源を使用する代わりに、バッテリーに充電された電力を用いて設備を駆動させる。代わりに、深夜などの電力料金が低い時間帯に再びバッテリーを充電させることができるようにする。 In other words, the facility is driven using the electric power charged in the battery instead of using the external power source during a time period when the electric power charge is relatively high due to the increase in electric power demand. Instead, the battery can be recharged at low power hours such as midnight.
図３を参照すると、例えば、１２時〜１７時の電力料金が相対的に高く、２３時〜０５時の電力料金が相対的に安いとすれば、毎日２３時〜０５時の間にバッテリーを充電させ、これを用いて１２時〜１７時の設備運用がなされるようにすることで、運用コストなどを大きく節減させることができる。 Referring to FIG. 3, for example, if the power charge from 12:00 to 17:00 is relatively high and the power charge from 23:00 to 05:00 is relatively low, the battery is charged every day from 23:00 to 05:00. By using this to operate the facility from 12:00 to 17:00, it is possible to greatly reduce operational costs and the like.
例えば、ピーク時間帯の電力料金がｋＷ当たり４，９５０ウォンで、深夜時間帯の電力料金がｋＷ当たり２，４００ウォンであると仮定すると、使用電力１００Ｗの設備において一日５時間（図３を参照）に対する節減コストは、１年に４６万ウォン程度に至ることを確認することができる（［参考式］）。 For example, if it is assumed that the power charge during peak hours is 4,950 won per kW and the power charge during midnight hours is 2,400 won per kW, a facility with a power consumption of 100 W will have 5 hours a day (see Fig. 3). It can be confirmed that the cost of saving is about 460,000 won per year ([reference formula]).
［参考式］
使用電力：１００Ｗ×５時間×３６５日＝１８２ｋＷ（同時負荷率１００％と見なす）
ピーク電力料金：１８２ｋＷ×４，９５０ウォン／ｋＷ＝９００，９００ウォン
深夜電力料金：１８２ｋＷ×２，４００ウォン／ｋＷ＝４３６，８００ウォン
節減効果：９００，９００ウォン−４３６，８００ウォン＝４６４，１００ウォン
[Reference formula]
Power consumption: 100 W x 5 hours x 365 days = 182 kW (considered to be 100% simultaneous load factor)
Peak electricity charge: 182 kW x 4,950 won / kW = 900,900 won Late-night electricity charge: 182 kW x 2,400 won / kW = 436,800 won Saving effect: 900,900 won-436,800 won = 464,100 won
このとき、バッテリー制御部は、管理者が運用時間及び運用モードを設定しまたは変更するための遠隔制御機能を提供する。以上のような機能を通じて運用コストの節減はもちろん、国家的に見て電力需要の分散などのような付加的な効果を提供できることが分かる。 At this time, the battery control unit provides a remote control function for the administrator to set or change the operation time and the operation mode. Through these functions, it can be seen that not only can operational costs be reduced, but additional effects such as distribution of power demand can be provided from a national perspective.
図４は、本発明の実施例に係る無停電電源供給装置に備えられる自動復旧モジュールの概略的な構成を示す説明図である。 FIG. 4 is an explanatory diagram showing a schematic configuration of an automatic recovery module provided in the uninterruptible power supply apparatus according to the embodiment of the present invention.
自動復旧モジュール４００は、電源遮断器（図示せず）が過電流、漏電または短絡の発生を感知して電源供給を遮断した場合、管理者による直接的な訪問操作がなくても、設備の機能を回復させることができるようにするための構成要素である。 When the power breaker (not shown) senses the occurrence of overcurrent, leakage or short circuit and shuts off the power supply, the automatic recovery module 400 functions as a facility even if there is no direct visit operation by the administrator. It is a component for making it possible to recover.
言い換えると、設備の保護のために動作する電源遮断器は、瞬間的なインパルス性ノイズなどにより作動される場合が非常に頻繁であり、この場合、僻地に位置した通信中継器などは電源遮断スイッチを原状回復させるために、管理者が直接遠距離の現場に訪問して手動でスイッチを操作するしかないという問題点があった。 In other words, power circuit breakers that operate to protect equipment are very often activated by momentary impulsive noise, etc. In this case, communication repeaters located in remote areas are powered off switches In order to restore the original state, there was a problem that an administrator had to visit a remote site directly and operate the switch manually.
したがって、設備に実際に致命的な問題が発生したのか、それとも、例えば、インパルス性ノイズなどのような一回性の原因により電源遮断器が作動したのかを、自動復旧モジュール４００がテスト信号の発生を通じて把握できるようにする。テスト信号による判断の結果、一回性の原因と判断されると、遠隔地で管理者の簡便な操作のみで自動復旧モジュール４００により電源遮断器の原状回復が可能なようにした。 Therefore, the automatic recovery module 400 generates a test signal whether the equipment actually has a fatal problem or whether the power breaker has been activated due to a one-time cause such as impulsive noise. To understand through. As a result of the determination based on the test signal, when the cause is determined to be one-time, the automatic recovery module 400 can restore the original state of the power breaker only by a simple operation of the administrator at a remote place.
この場合、電源遮断器が電子的に作動するスイッチで構成されれば、自動復旧モジュール４００から発生する信号のみで簡単に原状回復が可能であるが、通常の電源遮断器のような物理的な方式のスイッチなどで構成されれば、別途の駆動手段が要求されることがあり、これの構成を図４に例示した。 In this case, if the power breaker is configured with an electronically operated switch, the original state can be easily restored only by a signal generated from the automatic recovery module 400. If it is configured with a switch of the system, a separate driving means may be required, and this configuration is illustrated in FIG.
図４を参照すると、本発明の実施例に係る無停電電源供給装置に備えられる自動復旧モジュール４００は、電源部４１０、点検部４２０、制御部４３０及び駆動モータ４４０などを含んで構成されることが分かる。 Referring to FIG. 4, the automatic recovery module 400 included in the uninterruptible power supply apparatus according to the embodiment of the present invention includes a power supply unit 410, an inspection unit 420, a control unit 430, a drive motor 440, and the like. I understand.
電源部４１０は、外部から入力される通常のＡＣ電源などの入力により構成されることができ、無停電電源供給装置と独立した別途の電源の供給を受けるように構成されることがより好ましい。 The power supply unit 410 can be configured by an input such as a normal AC power input from the outside, and more preferably configured to receive a separate power supply independent of the uninterruptible power supply apparatus.
点検部４２０は、テスト信号などの発生を通じて、無停電電源供給装置に実際的な異常が発生したか否かを判断する機能を行う。点検部４２０により一回性の原因により電源遮断器が作動したと判断される場合には、制御部４３０が駆動モータ４４０の駆動を通じてスイッチを再び原状回復させることになる。駆動モータ４４０を用いたスイッチの操作やこれらの間の連結構造などは通常のいかなる方式でも可能である。 The inspection unit 420 performs a function of determining whether a practical abnormality has occurred in the uninterruptible power supply device through generation of a test signal or the like. If it is determined by the inspection unit 420 that the power breaker has been activated due to a one-time cause, the control unit 430 restores the switch to the original state again by driving the drive motor 440. The operation of the switch using the drive motor 440 and the connection structure between them can be performed by any ordinary method.
このような機能を通じて管理者の現場投入のような非効率的な作業を減少させることができ、これによるコスト節減などの効果を提供できるだけでなく、電源遮断時間を最小化させることによって、サービス品質の向上及び大型事故の予防などのような多様な効果を得ることができることが分かる。 Through these functions, inefficient work such as on-site management can be reduced, which not only provides cost savings and other benefits, but also minimizes power down time, thereby reducing service quality. It can be seen that various effects such as improvement of the situation and prevention of large accidents can be obtained.
なお、電源遮断器の反応速度を、印加される電流に対応するように４ミリ秒（ｍｓ）乃至１８秒に設定することによって、瞬間的な過電流などのように設備に大きな支障がない範囲の誤りに対しては、電源遮断器が反応しないようにする方法が適用されてもよい。すなわち、通常の無停電電源供給装置の場合、電源遮断器の反応速度がピコ秒（ｐｓ）単位まで小さく設定されることによって、インパルス性ノイズなどの瞬間的な誤りにもすぐに反応して作動するのに対して、本発明の実施例に係る無停電電源供給装置に適用される電源遮断器の場合、その反応速度を、設備に無理が行かない範囲内で最大値を持つように設定することによって、電源遮断器の作動による設備の稼動中断を最小化できるようにする。例えば、定格電流の１０倍の電流が印加される場合には、４ｍｓ乃至５８ｍｓの反応速度を有し、定格電流の２倍の電流が印加される場合には、１．４秒乃至１８秒程度の反応速度を有するようにする等の設定が可能である。 In addition, by setting the reaction rate of the power breaker to 4 milliseconds (ms) to 18 seconds so as to correspond to the applied current, there is no range where there is no big trouble in equipment such as instantaneous overcurrent. A method for preventing the power breaker from reacting to the error may be applied. In other words, in the case of a normal uninterruptible power supply system, the reaction speed of the power circuit breaker is set as small as picoseconds (ps) so that it reacts immediately to instantaneous errors such as impulsive noise. On the other hand, in the case of the power breaker applied to the uninterruptible power supply apparatus according to the embodiment of the present invention, the reaction speed is set so as to have the maximum value within a range where the equipment is not overwhelmed. Therefore, it is possible to minimize the interruption of the operation of the equipment due to the operation of the power breaker. For example, when a current 10 times the rated current is applied, the reaction speed is 4 ms to 58 ms, and when a current twice the rated current is applied, about 1.4 to 18 seconds. It is possible to set such that the reaction rate is as follows.
以上で説明した本発明の実施例に係る無停電電源供給装置において別途に説明されない多様な構成要素は、通常の多様な無停電電源供給装置に備えられるいかなる構成要素にも代替可能である。なお、バッテリーモジュールのリアルタイム状態表出のためのＬＥＤディスプレイ窓などを追加で備えることができることは上述の通りである。 Various components that are not separately described in the uninterruptible power supply apparatus according to the embodiment of the present invention described above can be replaced with any components that are provided in various normal uninterruptible power supply apparatuses. As described above, an LED display window or the like for displaying the battery module in real time can be additionally provided.
