しかしながら、商用電源１に、無停電電源装置２と消費電力が変動するその他の機器とが並列に接続されることもある。この場合には、無停電電源装置２が電力を消費するとともに、その他の機器でも電力を消費するので、総合消費電力（総合入力電力）が商用電源１の定格電源容量を超えることがあった。このため、商用電源１からの電源供給電力の総量を所定値に抑えることが望まれていた。   However, the commercial power supply 1 may be connected in parallel with the uninterruptible power supply 2 and other devices whose power consumption varies. In this case, the uninterruptible power supply 2 consumes power, and other devices also consume power, so that the total power consumption (total input power) sometimes exceeds the rated power capacity of the commercial power supply 1. For this reason, it has been desired to suppress the total amount of power supplied from the commercial power source 1 to a predetermined value.

本発明の課題は、商用電源からの電源供給電力の総量を商用電源の目標電源供給電力以内に抑えることができる電源装置及びその制御方法を提供することにある。   The subject of this invention is providing the power supply device which can suppress the total amount of the power supply power from a commercial power supply within the target power supply power of a commercial power supply, and its control method.

上記課題を解決するために、本発明の電源装置は、商用電源に無停電電源装置及び１以上の他の機器が接続される電源装置であって、前記無停電電源装置は、前記１以上の他の機器と前記無停電電源装置との総合入力電力が前記商用電源の目標電源供給電力を超えないように、前記無停電電源装置の入力電力を入力電力制限値により制限する制御器を備えることを特徴とする。  In order to solve the above problems, a power supply device of the present invention is a power supply device in which an uninterruptible power supply device and one or more other devices are connected to a commercial power supply, and the uninterruptible power supply device includes the one or more power supply devices. A controller is provided that limits the input power of the uninterruptible power supply by an input power limit value so that the total input power of other equipment and the uninterruptible power supply does not exceed the target power supply power of the commercial power supply. It is characterized by.

また、本発明の電源装置の制御方法は、商用電源に無停電電源装置及び１以上の他の機器が接続される電源装置の制御方法であって、前記無停電電源装置は、前記１以上の他の機器と前記無停電電源装置との総合入力電力が前記商用電源の目標電源供給電力を超えないように、前記無停電電源装置の入力電力を入力電力制限値により制限することを特徴とする。   The control method for a power supply device according to the present invention is a control method for a power supply device in which an uninterruptible power supply device and one or more other devices are connected to a commercial power supply, and the uninterruptible power supply device includes the one or more The input power of the uninterruptible power supply is limited by the input power limit value so that the total input power of the other equipment and the uninterruptible power supply does not exceed the target power supply power of the commercial power supply. .

本発明によれば、無停電電源装置の制御器は、１以上の他の機器と無停電電源装置との総合入力電力が商用電源の目標電源供給電力を超えないように、無停電電源装置の入力電力を入力電力制限値により制限するので、商用電源からの電源供給電力の総量を商用電源の目標電源供給電力以内に抑えることができる。   According to the present invention, the controller of the uninterruptible power supply is configured so that the total input power of one or more other devices and the uninterruptible power supply does not exceed the target power supply power of the commercial power supply.

以下、本発明の実施の形態の無停電電源装置を含む電源装置及びその制御方法を図面を参照しながら詳細に説明する。   Hereinafter, a power supply apparatus including an uninterruptible power supply apparatus according to an embodiment of the present invention and a control method thereof will be described in detail with reference to the drawings.

図１は、本発明の実施例１の無停電電源装置を含む電源装置の回路構成図である。図１に示す電源装置は、商用電源１に無停電電源装置２ａと消費電力が変動するその他機器４ａ，４ｂ（１以上の他の機器に対応）とが並列に接続されている。   1 is a circuit configuration diagram of a power supply apparatus including an uninterruptible power supply apparatus according to Embodiment 1 of the present invention. In the power supply device shown in FIG. 1, an uninterruptible power supply 2a and other devices 4a and 4b (corresponding to one or more other devices) whose power consumption fluctuates are connected to a commercial power supply 1 in parallel.

商用電源１からの電源供給電力の総量を所定値（商用電源１の目標電源供給電力以内）に抑えることを目的に、無停電電源装置２ａは、その他機器４ａ，４ｂと無停電電源装置２ａとの総合入力電力が目標電源供給電力を超えないように、無停電電源装置２ａの入力電力を入力電力制限値により制限する制御器２８ａを備える。   For the purpose of suppressing the total amount of power supply power from the commercial power supply 1 to a predetermined value (within the target power supply power of the commercial power supply 1), the uninterruptible power supply 2a includes other devices 4a and 4b, the uninterruptible power supply 2a, The controller 28a is provided to limit the input power of the uninterruptible power supply 2a with the input power limit value so that the total input power of the power supply does not exceed the target power supply power.

なお、目標電源供給電力は商用電源１の定格電源容量とは限らず、電源事情により可変とする場合もある。   The target power supply power is not limited to the rated power capacity of the commercial power supply 1 and may be variable depending on the power supply situation.

図１において、商用電源１の出力端と無停電電源装置２ａ及びその他機器４ａ，４ｂの入力端との間には電流検出器５が接続される。電流検出器５は、商用電源１の出力端に流れるその他機器４ａ，４ｂの電流と無停電電源装置２ａに流れ込む電流との総合電流Ｉｓを検出して制御器２８ａに出力する。   In FIG. 1, a current detector 5 is connected between the output end of the commercial power source 1 and the input ends of the uninterruptible power supply 2a and other devices 4a and 4b. The current detector 5 detects the total current Is of the currents of the other devices 4a and 4b flowing at the output terminal of the commercial power supply 1 and the current flowing into the uninterruptible power supply 2a, and outputs it to the controller 28a.

制御器２８ａは、電流検出器５からの総合電流Ｉｓと商用電源１の出力端の電圧Ｖｓとに基づき電源供給電力の総量（総合入力電力）を算出し、電流検出器２４で検出された電流Ｉｉｎと無停電電源装置２ａの入力端の電圧Ｖｉｎとに基づき無停電電源装置２ａの入力電力を算出し、電源供給電力の総量と無停電電源装置２ａの入力電力と商用電源１の目標電源供給電力とに基づき無停電電源装置２ａの入力電力制限値を設定する。具体的には、無停電電源装置２ａの入力電力制限値は、目標電源供給電力−（電源供給電力の総量−無停電電源装置の入力電力）により求められる。   The controller 28a calculates the total amount of power supply power (total input power) based on the total current Is from the current detector 5 and the voltage Vs at the output terminal of the commercial power supply 1, and the current detected by the current detector 24. The input power of the uninterruptible power supply 2a is calculated based on Iin and the input terminal voltage Vin of the uninterruptible power supply 2a, and the total power supply power, the input power of the uninterruptible power supply 2a, and the target power supply of the commercial power supply 1 are calculated. Based on the power, the input power limit value of the uninterruptible power supply 2a is set. Specifically, the input power limit value of the uninterruptible power supply 2a is obtained by target power supply power− (total amount of power supply power−input power of the uninterruptible power supply).

制御器２８ａは、無停電電源装置２ａの入力電力制限値を制御することにより、無停電電源装置２ａの入力電力を制限し、商用電源１には目標電源供給電力範囲内で最大限の電力を供給させつつ、負荷３への電力供給不足分を二次電池２６から補う。  The controller 28a controls the input power limit value of the uninterruptible power supply 2a to limit the input power of the uninterruptible power supply 2a, and the commercial power supply 1 has the maximum power within the target power supply power range. While the power is being supplied, the shortage of power supply to the load 3 is compensated from the secondary battery 26.

また、制御器２８ａは、目標電源供給電力がその他機器４ａ，４ｂを含めた総合入力電力から二次電池２６の充電電力を差し引いた電力を超える場合には、余剰電力で二次電池２６を充電させる。その他機器４ａ，４ｂを含めた総合入力電力から二次電池２６の充電電力を差し引いた電力を目標電源供給電力から差し引いた電力が余剰電力となる。  In addition, when the target power supply power exceeds the power obtained by subtracting the charging power of the secondary battery 26 from the total input power including the other devices 4a and 4b, the controller 28a charges the secondary battery 26 with surplus power. Let The power obtained by subtracting the power obtained by subtracting the charging power of the secondary battery 26 from the total input power including the other devices 4a and 4b from the target power supply power is the surplus power.

ここで、その他機器４ａ，４ｂを含めた総合入力電力とは、その他機器４ａ，４ｂの消費電力の総和、無停電電源装置２ａの負荷３の消費電力、二次電池２６の充電電力、無停電電源装置２ａの電力損失の合計電力である。即ち、その他機器４ａ，４ｂ及び無停電電源装置２ａに入力される入力電力の合計である。  Here, the total input power including the other devices 4a and 4b is the sum of the power consumption of the other devices 4a and 4b, the power consumption of the load 3 of the uninterruptible power supply 2a, the charging power of the secondary battery 26, and the uninterruptible power. This is the total power loss of the power supply device 2a. That is, it is the total input power input to the other devices 4a and 4b and the uninterruptible power supply 2a.

図２は、本発明の実施例１の無停電電源装置を含む電源装置の説明図である。なお、ＡＣ−ＤＣ変換器２１、ＤＣ−ＡＣ変換器２２の電力損失は無視してある。図２において、目標電源供給電力を時間軸方向の中央付近で変化させている。斜線部分が無停電電源装置２ａ以外の機器の消費電力の合計である。図２では、本発明を理解し易いようにその他機器４ａ，４ｂの入力電力の合計は、目標電源供給電力線をゼロレベルとして、消費電力が大きいと負方向に広がるように表示している。斜線部分の境界線と入力電力保護制限値との小さい方が本発明の入力電力制限値となる。  FIG. 2 is an explanatory diagram of a power supply apparatus including the uninterruptible power supply apparatus according to the first embodiment of the present invention. Note that power loss of the AC-DC converter 21 and the DC-AC converter 22 is ignored. In FIG. 2, the target power supply power is changed near the center in the time axis direction. The shaded portion is the total power consumption of devices other than the uninterruptible power supply 2a. In FIG. 2, for easy understanding of the present invention, the total input power of the other devices 4 a and 4 b is displayed so as to spread in the negative direction when the power consumption is large with the target power supply power line set to zero level. The smaller one of the boundary of the hatched portion and the input power protection limit value is the input power limit value of the present invention.

図３は、本発明の実施例１の無停電電源装置にその他の機器を含めた総合入力電力が目標電源供給電力以下である場合の電力フローを示す図である。目標電源供給電力が、その他機器４ａ，４ｂの入力電力と無停電電源装置２ａの入力電力との総合入力電力を超えている場合には、図２からもわかるように、無停電電源装置２ａの入力電力（ＵＰＳ入力電力）は、入力電力制限値（点線部分）よりも小さい。  FIG. 3 is a diagram illustrating a power flow when the total input power including other devices in the uninterruptible power supply according to the first embodiment of the present invention is equal to or less than the target power supply power. When the target power supply power exceeds the total input power of the input power of the other devices 4a and 4b and the uninterruptible power supply 2a, as can be seen from FIG. 2, the uninterruptible power supply 2a The input power (UPS input power) is smaller than the input power limit value (dotted line portion).

この場合には、商用電源１からその他機器４ａ，４ｂに電力が供給されるとともに、無停電電源装置２ａに入力された入力電力は、負荷３に負荷電力として供給され、入力電力Ｐ３から負荷電力Ｐ４を差し引いた余剰電力により二次電池２６が充電される。  In this case, power is supplied from the commercial power supply 1 to the other devices 4a and 4b, and the input power input to the uninterruptible power supply 2a is supplied as load power to the load 3, and the load power is input from the input power P3. The secondary battery 26 is charged with surplus power obtained by subtracting P4.

図４は、本発明の実施例１の無停電電源装置にその他の機器４ａ，４ｂを含めた総合入力電力が目標電源供給電力を超える場合の電力フローを示す図である。その他の機器４ａ，４ｂを含めた総合入力電力が目標電源供給電力を超える場合には、図２からもわかるように、無停電電源装置２ａの入力電力制限値により無停電電源装置２ａの入力電力が制限される。  FIG. 4 is a diagram illustrating a power flow when the total input power including the other devices 4a and 4b in the uninterruptible power supply device according to the first embodiment of the present invention exceeds the target power supply power. When the total input power including other devices 4a and 4b exceeds the target power supply power, as can be seen from FIG. 2, the input power of the uninterruptible power supply 2a is determined by the input power limit value of the uninterruptible power supply 2a. Is limited.

商用電源１の供給する電力が目標電源供給電力以内になるように、無停電電源装置２ａが入力する入力電力を入力電力制限値により制限して、負荷３の電力から制限された入力電力を差し引いた電力、即ち負荷３への供給不足分の電力を二次電池２６から供給している。
このように実施例１の電源装置によれば、商用電源１に並列にその他機器４ａ，４ｂと無停電電源装置２ａとが接続されている場合に、無停電電源装置２ａの制御器２８ａは、その他機器４ａ，４ｂと無停電電源装置２ａとの総合入力電力が商用電源１の目標電源供給電力を超えないように、無停電電源装置２ａの入力電力を入力電力制限値により制限するので、商用電源１からの電源供給電力の総量を商用電源１の目標電源供給電力以内に抑えることができる。 The input power input by the uninterruptible power supply 2a is limited by the input power limit value so that the power supplied by the commercial power supply 1 is within the target power supply power, and the limited input power is subtracted from the power of the load 3. In other words, the secondary battery 26 supplies insufficient power, that is, insufficient power to the load 3.
Thus, according to the power supply device of Example 1, when the other devices 4a and 4b and the uninterruptible power supply 2a are connected in parallel to the commercial power supply 1, the controller 28a of the uninterruptible power supply 2a is Since the input power of the uninterruptible power supply 2a is limited by the input power limit value so that the total input power of the other devices 4a, 4b and the uninterruptible power supply 2a does not exceed the target power supply power of the commercial power supply 1, The total amount of power supply power from the power source 1 can be suppressed within the target power supply power of the commercial power source 1.

図５は、本発明の実施例２の無停電電源装置を含む電源装置の回路構成図である。図５に示す実施例２の電源装置は、その他機器４ａに流れる電流を検出する電流検出器６ａ、その他機器４ｂに流れる電流を検出する電流検出器６ｂを備え、制御器２８ｂは、電流検出器６ａで検出された電流とその他機器４ａの入力電圧Ｖｉｎ１とに基づきその他機器４ａの入力電力を算出し、電流検出器６ｂで検出された電流とその他機器４ｂの入力電圧Ｖｉｎ２とに基づきその他機器４ｂの入力電力を算出し、その他機器４ａ，４ｂの総合入力電力を算出する。   FIG. 5 is a circuit configuration diagram of a power supply device including the uninterruptible power supply device according to the second embodiment of the present invention. 5 includes a current detector 6a for detecting a current flowing through the other device 4a and a current detector 6b for detecting a current flowing through the other device 4b. The controller 28b includes a current detector. The input power of the other device 4a is calculated based on the current detected by the device 6a and the input voltage Vin1 of the other device 4a, and the other device 4b is calculated based on the current detected by the current detector 6b and the input voltage Vin2 of the other device 4b. And the total input power of the other devices 4a and 4b is calculated.

制御器２８ｂは、商用電源１の目標電源供給電力からその他機器４ａ，４ｂの総合入力電力を差し引いた差分電力を入力電力制限値として設定する。   The controller 28b sets the differential power obtained by subtracting the total input power of the other devices 4a and 4b from the target power supply power of the commercial power supply 1 as the input power limit value.

このような実施例２の電源装置においても、実施例１の電源装置と同様に、無停電電源装置２ｂの入力電力を入力電力制限値により制限するので、商用電源１からの電源供給電力の総量を商用電源１の目標電源供給電力以内に抑えることができる。  Also in the power supply device of the second embodiment, as in the power supply device of the first embodiment, the input power of the uninterruptible power supply device 2b is limited by the input power limit value, so the total amount of power supply power from the commercial power supply 1 Can be suppressed within the target power supply power of the commercial power source 1.

図６は、本発明の実施例３の無停電電源装置を含む電源装置の回路構成図である。図６に示す実施例３の電源装置は、一次側が商用電源１の出力端とその他機器４ａ，４ｂの入力端とに接続され、二次側が無停電電源装置２ｃの入力端に接続されたトランス７を備えている。制御器２８ｃは、さらに、トランス７の巻数及びレギュレーションに基づき入力電力制限値を設定することを特徴とする。   FIG. 6 is a circuit configuration diagram of a power supply device including the uninterruptible power supply device according to the third embodiment of the present invention. The power supply device of Example 3 shown in FIG. 6 is a transformer in which the primary side is connected to the output end of the commercial power supply 1 and the input ends of the other devices 4a and 4b, and the secondary side is connected to the input end of the uninterruptible power supply 2c. 7 is provided. The controller 28c is further characterized in that the input power limit value is set based on the number of turns of the transformer 7 and the regulation.

このような実施例３の電源装置においても、トランス７の巻数及びレギュレーションを考慮して、無停電電源装置２ｃの入力電力を入力電力制限値により制限するので、商用電源１からの電源供給電力の総量を商用電源１の目標電源供給電力以内に抑えることができる。  Also in the power supply device of the third embodiment, the input power of the uninterruptible power supply device 2c is limited by the input power limit value in consideration of the number of turns of the transformer 7 and the regulation. The total amount can be suppressed within the target power supply power of the commercial power source 1.
