Connected through. The number of generators 1 is set based on the maximum power required by the ship.

更に電力設備は、電力を消費する電力消費部を備えており、電力消費部は主配電盤のメイン回路２に、切替手段５，６，７を有する複数の回路８，９，１０を介して接続されており、電力消費部をコンテナ船の例で示すと、電力消費部は、船舶の推進及び船舶内の必要電力からなる第一電力消費系統１１と、船舶に冷凍コンテナ等の荷を積載した際に生じる第二電力消費系統１２と、船舶を横方向へ動かすバウスラスタを駆動し得るようバウスラスタ電動機１４及び始動器１３からなる第三電力消費系統１５とを備えている。 Further, the power facility includes a power consuming unit that consumes power, and the power consuming unit is connected to the main circuit 2 of the main switchboard via a plurality of circuits 8, 9, and 10 having switching means 5, 6, and 7. When the power consumption unit is shown as an example of a container ship, the power consumption unit is loaded with a load such as a refrigerated container and the like on the first power consumption system 11 composed of propulsion of the ship and necessary power in the ship. A second power consumption system 12 generated at the time and a third power consumption system 15 including a bow thruster motor 14 and a starter 13 are provided so as to drive a bow thruster that moves the ship in the lateral direction.

このような電力設備のコンテナ船を運航する際には、通常航行時、出入港時、荷役時の電力需要に応じて発電機１の稼働台数を制御しており、コンテナ船が冷凍コンテナを積載し且つバウスラスタを駆動して出入港する場合には発電機１を全て稼働して第一電力消費系統１１、第二電力消費系統１２、第三電力消費系統１５に対応しており、コンテナ船が冷凍コンテナを積載して通常航行する場合や冷凍コンテナを荷役する場合には、発電機１のうち数台を使用して第一電力消費系統１１及び第二電力消費系統１２に対応しており、コンテナ船が冷凍コンテナを積載することなく運航する場合には、発電機１のうち１台または２台を使用して第一電力消費系統１１に対応するようにしている。 When operating a container ship with such a power facility, the number of generators 1 is controlled according to the power demand during normal navigation, entry / exit, and cargo handling, and the container ship carries refrigerated containers.

以下本発明を実施する形態の第一例の作用を説明する。 The operation of the first embodiment of the present invention will be described below.

コンテナ船等の船舶を運航する際には、通常の航行時、出入港時、荷役時の電力需要に対応するよう、エネルギー貯蔵手段の蓄電池装置２５のみで給電する単独給電モード、エネルギー貯蔵手段の蓄電池装置２５を充電（充填）する充電モード（充填モード）、エネルギー貯蔵手段の蓄電池装置２５により発電手段の発電機１を補助するアシストモード、エネルギー貯蔵手段の蓄電池装置２５を休止する休止モードを選択し、発電機１と蓄電池装置２５の使用を制御する。 When operating a vessel such as a container ship, a single power supply mode in which power is supplied only by the storage battery device 25 of the energy storage means so as to correspond to the power demand at the time of normal navigation, entry / exit, and cargo handling, A charging mode (charging mode) for charging (charging) the storage battery device 25, an assist mode for assisting the generator 1 of the power generation means by the storage battery device 25 of the energy storage means, and a sleep mode for stopping the storage battery device 25 of the energy storage means are selected. The use of the generator 1 and the storage battery device 25 is controlled.

具体的には、コンテナ船等の船舶が運航する場合には、図３に示すフローに示す如く、制御部３２により、予め設定された発電機１の負荷率の基準値（％）と、発電機１の実際の負荷率とを比較し（ステップＳ１）、発電機１の実際の負荷率が基準値（％）よりも小さい場合（ステップＳ１のＮＯ）には、予め設定された蓄電池装置２５の蓄電量の基準値（ｋＷｈ）と、蓄電池装置２５の実際の蓄電量とを比較する段階（ステップＳ２）へ移行する。そして蓄電池装置２５の実際の蓄電量を比較する段階（ステップＳ２）では蓄電池装置２５の実際の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ２のＹＥＳ）に、単独給電モードに移行する（ステップＳ３）。 Specifically, when a vessel such as a container ship operates, the control unit 32 sets a preset load factor reference value (%) and power generation as shown in the flow of FIG. The actual load factor of the generator 1 is compared (step S1). If the actual load factor of the generator 1 is smaller than the reference value (%) (NO in step S1), the preset storage battery device 25 The process proceeds to the step of comparing the reference value (kWh) of the stored amount of electricity with the actual stored amount of storage battery device 25 (step S2). Then, in the stage of comparing the actual power storage amount of the storage battery device 25 (step S2), when the actual power storage amount of the storage battery device 25 is larger than the reference value (kWh) (YES in step S2), the mode is shifted to the single power supply mode. (Step S3).

単独給電モード（ステップＳ３）では制御部３２から切替手段１７，２８，３０に制御信号を送り、図４に示す如く、第一の給電側切替手段１７の切替により第一給電回路１８を遮断して発電機１を停止し、また第二の給電側切替手段２８の切替により第二給電回路２９を接続し、蓄電池装置２５の電力のみを第一電力消費系統１１及び第二電力消費系統１２へ給電する。 In the single power supply mode (step S3), a control signal is sent from the control unit 32 to the switching means 17, 28, 30 and the first power supply circuit 18 is shut off by switching the first power supply side switching means 17, as shown in FIG. Then, the generator 1 is stopped, and the second power feeding circuit 29 is connected by switching the second power feeding side switching means 28, and only the power of the storage battery device 25 is sent to the first power consuming system 11 and the second power consuming system 12. Supply power.

一方、制御部３２では、図３に示す如く、単独給電モード（ステップＳ３）であっても、常に、予め設定された蓄電池装置２５の蓄電量の基準値（ｋＷｈ）と、蓄電池装置２５の現状の蓄電量とを比較しており（ステップＳ４）、蓄電池装置２５の現状の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ４のＮＯ）には単独給電モードを維持し（ステップＳ３）、蓄電池装置２５の現状の蓄電量が基準値（ｋＷｈ）より小さい場合（ステップＳ４のＹＥＳ）には、制御部３２は発電機１を始動し、第一の給電側切替手段１７の切替により第一給電回路１８を接続して単独給電モードを終了し（ステップＳ５）、最初の段階へ移行する。ここで図３の符号Ａは最初の段階へ戻ることを示している。 On the other hand, as shown in FIG. 3, the control unit 32 always has a preset reference value (kWh) of the storage battery device 25 and the current state of the storage battery device 25 even in the single power supply mode (step S 3). When the current storage amount of the storage battery device 25 is larger than the reference value (kWh) (NO in step S4), the single power supply mode is maintained (step S3). When the current storage amount of the storage battery device 25 is smaller than the reference value (kWh) (YES in step S4), the control unit 32 starts the generator 1 and switches the first power supply side switching means 17 to The single power supply circuit 18 is connected to end the single power supply mode (step S5), and the process proceeds to the first stage. Here, the symbol A in FIG. 3 indicates that the process returns to the first stage.

次に、制御部３２により、予め設定された蓄電池装置２５の蓄電量の基準値（ｋＷｈ）と、蓄電池装置２５の実際の蓄電量とを比較する段階（ステップＳ２）で、蓄電池装置２５の実際の蓄電量が基準値（ｋＷｈ）よりも小さい場合（ステップＳ２のＮＯ）には充電モード（充填モード）に移行する（ステップＳ６）。 Next, the control unit 32 compares the preset reference value (kWh) of the storage amount of the storage battery device 25 with the actual storage amount of the storage battery device 25 (step S2). When the stored amount of electricity is smaller than the reference value (kWh) (NO in step S2), the charging mode (charging mode) is entered (step S6).

充電モード（ステップＳ６）では制御部３２から切替手段２８，３０に制御信号を送り、図５に示す如く、第二の給電側切替手段２８の切替により第二給電回路２９を接続し、発電機１の電力を回収して蓄電池装置２５へ充電する。また充電モードでは、発電機１の電力により第一電力消費系統１１へ給電する。 In the charging mode (step S6), a control signal is sent from the control unit 32 to the switching means 28, 30, and the second power feeding circuit 29 is connected by switching the second power feeding side switching means 28 as shown in FIG. 1 is collected and charged to the storage battery device 25. In the charging mode, power is supplied to the first power consumption system 11 by the power of the generator 1.

一方、制御部３２では、図３に示す如く、充電モード（ステップＳ６）であっても、常に、予め設定された蓄電池装置２５の蓄電量の基準値（ｋＷｈ）と、蓄電池装置２５の現状の蓄電量とを比較しており（ステップＳ７）、蓄電池装置２５の現状の蓄電量が基準値（ｋＷｈ）よりも小さい場合（ステップＳ７のＮＯ）には充電モードを維持し（ステップＳ６）、蓄電池装置２５の現状の蓄電量が基準値（ｋＷｈ）より大きい場合（ステップＳ７のＹＥＳ）には充電モードを終了し（ステップＳ８）、最初の段階へ移行する。 On the other hand, as shown in FIG. 3, the control unit 32 always maintains the preset reference value (kWh) of the storage battery device 25 and the current state of the storage battery device 25 even in the charging mode (step S 6). When the current storage amount of the storage battery device 25 is smaller than the reference value (kWh) (NO in step S7), the charge mode is maintained (step S6). If the current charged amount of the device 25 is larger than the reference value (kWh) (YES in step S7), the charging mode is terminated (step S8), and the process proceeds to the first stage.

続いて、制御部３２により、予め設定された発電機１の負荷率の基準値（％）と、発電機１の実際の負荷率とを比較する段階（ステップＳ１）で、発電機１の実際の負荷率が基準値（％）よりも大きい場合（ステップＳ１のＹＥＳ）には、予め設定された蓄電池装置２５の蓄電量の基準値（ｋＷｈ）と、蓄電池装置２５の実際の蓄電量とを比較する段階（ステップＳ９）へ移行する。そして蓄電池装置２５の実際の蓄電量を比較する段階（ステップＳ９）では蓄電池装置２５の実際の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ９のＹＥＳ）に、アシストモードに移行する（ステップＳ１０）。 Subsequently, the control unit 32 compares the preset reference value (%) of the load factor of the generator 1 with the actual load factor of the generator 1 (step S1). Is larger than the reference value (%) (YES in step S1), the preset reference value (kWh) of the storage amount of the storage battery device 25 and the actual storage amount of the storage battery device 25 are obtained. The process proceeds to the comparison stage (step S9). Then, in the stage of comparing the actual power storage amount of the storage battery device 25 (step S9), when the actual power storage amount of the storage battery device 25 is larger than the reference value (kWh) (YES in step S9), the mode shifts to the assist mode ( Step S10).

アシストモード（ステップＳ１０）では制御部３２から切替手段２８，３０に制御信号を送り、図６に示す如く、第二の給電側切替手段２８の切替により第二給電回路２９を接続し、第三回路２４を接続した状態で、蓄電池装置２５により発電機１の給電を補助し、第一電力消費系統１１、第二電力消費系統１２、第三電力消費系統１５へ給電し、最大電力に対応する。これによりアシストモードは、発電機１及び蓄電池装置２５を並列で用いてバウスラスタを駆動する状態になる。 In the assist mode (step S10), a control signal is sent from the control section 32 to the switching means 28, 30, and the second power feeding circuit 29 is connected by switching the second power feeding side switching means 28 as shown in FIG. With the circuit 24 connected, the storage battery device 25 assists the power supply of the generator 1, supplies power to the first power consumption system 11, the second power consumption system 12, and the third power consumption system 15, and corresponds to the maximum power. . Thereby, the assist mode is in a state in which the bow thruster is driven using the generator 1 and the storage battery device 25 in parallel.

ここで、単独給電モード、充電モード、アシストモードのいずれも、蓄電池装置２５から冷凍コンテナの第二電力消費系統１２へ給電する場合には、冷凍コンテナの搭載量に応じて、適宜、第三の給電側切替手段３０の切替により第三給電回路３１を遮断または接続することも可能である。 Here, in any of the single power supply mode, the charging mode, and the assist mode, when power is supplied from the storage battery device 25 to the second power consumption system 12 of the refrigerated container, the third power supply is appropriately selected according to the amount of the refrigerated container mounted. It is also possible to cut off or connect the third power feeding circuit 31 by switching the power feeding side switching means 30.

一方、制御部３２では、図３に示す如く、アシストモード（ステップＳ１０）であっても、常に、予め設定された蓄電池装置２５の蓄電量の基準値（ｋＷｈ）と、蓄電池装置２５の現状の蓄電量とを比較しており（ステップＳ１１）、蓄電池装置２５の現状の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ１１のＮＯ）にはアシストモードを維持し（ステップＳ１１）、蓄電池装置２５の現状の蓄電量が基準値（ｋＷｈ）より小さい場合（ステップＳ１１のＹＥＳ）にはアシストモードを終了し（ステップＳ１２）、最初の段階へ移行する。 On the other hand, as shown in FIG. 3, the control unit 32 always maintains the preset reference value (kWh) of the storage battery device 25 and the current state of the storage battery device 25 even in the assist mode (step S 10). When the current storage amount of the storage battery device 25 is larger than the reference value (kWh) (NO in step S11), the assist mode is maintained (step S11). If the current power storage amount of the device 25 is smaller than the reference value (kWh) (YES in step S11), the assist mode is ended (step S12), and the process proceeds to the first stage.

更に、制御部３２により、予め設定された蓄電池装置２５の蓄電量の基準値（ｋＷｈ）と、蓄電池装置２５の実際の蓄電量とを比較する段階（ステップＳ９）で、蓄電池装置２５の実際の蓄電量が基準値（ｋＷｈ）よりも小さい場合（ステップＳ９のＮＯ）には休止モードに移行する（ステップＳ１３）。 Furthermore, the control unit 32 compares the preset reference value (kWh) of the storage amount of the storage battery device 25 with the actual storage amount of the storage battery device 25 (step S9). When the charged amount is smaller than the reference value (kWh) (NO in step S9), the operation mode is shifted to the pause mode (step S13).

休止モード（ステップＳ１３）では制御部３２から切替手段２８，３０に制御信号を送り、図７に示す如く、第二の給電側切替手段２８の切替により第二給電回路２９を遮断すると共に第三の給電側切替手段３０の切替により第三給電回路３１を遮断し、蓄電池装置２５を全ての回路から切り離すと共に発電機１の電力を第一電力消費系統１１等へ給電する。更に第三切替手段２３の切替により第三回路２４を遮断し、これにより休止モードは、蓄電池装置２５を用いることなく、発電機１の電力を船舶の推進及び船舶内の必要電力に給電する。 In the sleep mode (step S13), a control signal is sent from the control unit 32 to the switching means 28, 30, and the second power feeding circuit 29 is shut off by switching the second power feeding side switching means 28 as shown in FIG. By switching the power supply side switching means 30, the third power supply circuit 31 is cut off, the storage battery device 25 is disconnected from all the circuits, and the power of the generator 1 is supplied to the first power consumption system 11 and the like. Further, the third circuit 24 is cut off by the switching of the third switching means 23, whereby the sleep mode supplies the power of the generator 1 to the propulsion of the ship and the necessary power in the ship without using the storage battery device 25.

一方、制御部３２では、図３に示す如く、休止モード（ステップＳ１３）をそのまま最初の段階へ移行し、再度、単独給電モード、充電モード、アシストモード、休止モードを選択する。 On the other hand, as shown in FIG. 3, the control unit 32 shifts the sleep mode (step S 13) to the first stage as it is, and again selects the single power supply mode, the charge mode, the assist mode, and the sleep mode.

その後、船舶の運航に基づいて単独給電モード、充電モード、アシストモード、休止モードの選択を繰り返して発電機１及び蓄電池装置２５を連続的に制御することが可能となる。ここで、単独給電モード、充電モード、アシストモード、休止モードの選択は、他の制御に基づくものでも良く、更に制御部３２には、発電機１や圧縮流体貯蔵装置の給電を人為的に停止する緊急停止モードや、発電機１や蓄電池装置２５の給電を人為的に変更する変更モードを備えても良く、特に条件が制限されるものではない。 Thereafter, the generator 1 and the storage battery device 25 can be controlled continuously by repeatedly selecting the single power supply mode, the charging mode, the assist mode, and the suspension mode based on the operation of the ship. Here, the selection of the single power supply mode, the charge mode, the assist mode, and the sleep mode may be based on other control, and the control unit 32 artificially stops power supply to the generator 1 and the compressed fluid storage device. There may be provided an emergency stop mode, and a change mode for artificially changing the power supply of the generator 1 and the storage battery device 25, and the conditions are not particularly limited.

Furthermore, according to the configuration of the first example of the embodiment, the generator 1 can be operated with the most efficient load of 80% to 85%, and the energy efficiency can be optimally increased.

また実施の形態の第一例によれば、発電手段の発電機１の発電容量を低減すると共に発電手段の発電機１からエネルギー貯蔵手段の蓄電池装置２５へ充電し得るので、不必要な発電を減らし、ＧＨＧ（Green House Gas）削減を図り、地球温暖化問題に好適に対応することができる。 Further, according to the first example of the embodiment, the power generation capacity of the generator 1 of the power generation means can be reduced and the storage battery device 25 of the energy storage means can be charged from the power generator 1 of the power generation means. It is possible to reduce GHG (Green House Gas) and cope with the global warming problem.

Energy efficiency by reducing the first power generation capacity can be adequately increased.

実施の形態の第一例において、エネルギー貯蔵手段は蓄電池装置２５であると、蓄電池装置２５を適切に設置し得るので、発電機１の発電容量を容易に小さくしてエネルギー効率を高めることができる。 In the first example of the embodiment, when the energy storage means is the storage battery device 25, the storage battery device 25 can be appropriately installed, so that the power generation capacity of the generator 1 can be easily reduced to increase the energy efficiency. .

実施の形態の第一例において、電力消費部は、船舶の推進及び船舶内の必要電力からなる第一電力消費系統１１と、船舶に冷凍コンテナ等の荷を積載した際に生じる第二電力消費系統１２と、バウスラスタ等の船舶の補助推進手段の駆動による第三電力消費系統１５とを備え、第三電力消費系統１５を用いる場合にはアシストモードで処理するように構成すると、第一電力消費系統１１、第二電力消費系統１２、第三電力消費系統１５に応じて発電機１及び蓄電池装置２５を容易に適合させるので、製造コストを低減することができる。 In the first example of the embodiment, the power consumption unit includes a first power consumption system 11 including propulsion of the ship and necessary power in the ship, and second power consumption generated when a load such as a refrigerated container is loaded on the ship. If the system 12 and the third power consumption system 15 driven by the auxiliary propulsion means of the ship such as a bow thruster are provided and the third power consumption system 15 is used, the first power consumption Since the generator 1 and the storage battery device 25 are easily adapted according to the system 11, the second power consumption system 12, and the third power consumption system 15, the manufacturing cost can be reduced.

以下、本発明の実施の形態の第二例を図８を参照して説明する。図中、図１〜図７と同一の符号を付した部分は同一物を表している。 Hereinafter, a second example of the embodiment of the present invention will be described with reference to FIG. In the figure, the same reference numerals as those in FIGS. 1 to 7 denote the same components.

本発明の船舶の電力設備及びその運用方法の形態の第二例は、第一例のエネルギー貯蔵手段の構成及びその切替手段を変更したものであり、その他の発電手段、電力消費部、回路は第一例と略同じ構成を備えている。 The second example of the ship power equipment and its operation method of the present invention is a modification of the configuration of the energy storage means and the switching means of the first example, and the other power generation means, power consumption unit, and circuit are It has substantially the same configuration as the first example.

エネルギー貯蔵手段は、圧縮空気貯蔵装置３３ａや圧縮油圧貯蔵装置３３ｂ等の圧縮流体や気体の貯蔵装置で構成されており、圧縮空気貯蔵装置３３ａは、発電機１からの電気エネルギーにより空気を圧縮するコンプレッサ３４と、コンプレッサ３４により圧縮空気としてエネルギーを貯蔵し得る空気槽３５ａと、空気槽３５ａからエネルギーを取り出し且つ電気エネルギーに変換し得る空気駆動式モータ３６と、空気駆動式モータ３６に直結する貯蔵側発電機３７と、貯蔵側発電機３７の切替手段３７ａと、コンプレッサ３４を始動させる始動器３８及び電動機３９とを備えている。また始動器３８は、主配電盤のメイン回路１６に、第四切替手段４０を有する第四回路４１を介して接続されている。更に圧縮空気貯蔵装置３３ａの貯蔵側発電機３７は、主配電盤のメイン回路１６に、第四の給電側切替手段４２を有する第四給電回路４３を介して接続されていると共に、第四給電回路４３と分岐するよう、第二電力消費系統１２に、第五の給電側切替手段４４を有する第五給電回路４５を介して接続されている。一方、圧縮油圧貯蔵装置３３ｂは、圧縮空気貯蔵装置３３ａと略同様に、発電機１からの電気エネルギーにより油圧を圧縮する油圧ポンプ電動機３９と、油圧ポンプ３４により油圧エネルギーを貯蔵し得る油液槽３５ｂと、油液槽３５ｂからエネルギーを取り出し得る油圧モータ３６と、油圧モータ３６と直結する貯蔵側発電機３７と、油圧ポンプ電動機３９を始動させる始動器３８とを備え、略同様に、メイン回路１６及び第二電力消費系統１２に接続されている。 The energy storage means is composed of a compressed fluid or gas storage device such as a compressed air storage device 33a or a compressed hydraulic storage device 33b, and the compressed air storage device 33a compresses air by electric energy from the generator 1. Compressor 34, air tank 35a that can store energy as compressed air by compressor 34, air-driven motor 36 that can extract energy from air tank 35a and convert it into electrical energy, and storage that is directly connected to air-driven motor 36 A side generator 37, a switching means 37a for the storage side generator 37, a starter 38 for starting the compressor 34, and an electric motor 39 are provided.

Furthermore, a predetermined function is set inside the control unit 32, and a reference value for the power generation load factor of the generator 1 and a reference value for the amount of electricity stored in the compressed fluid storage device are input in advance. A control signal is sent to each switching means according to the power generation load factor and the converted value of the amount of energy stored in the compressed fluid storage device (hereinafter referred to as “storage amount”).

以下本発明を実施する形態の第二例の作用を説明する。 The operation of the second embodiment of the present invention will be described below.

コンテナ船等の船舶を運航する際には、第一例と略同様に、通常の航行時、出入港時、荷役時の電力需要に対応するよう、エネルギー貯蔵手段の圧縮流体貯蔵装置のみで給電する単独給電モード、エネルギー貯蔵手段の圧縮流体貯蔵装置を充填する充填モード、エネルギー貯蔵手段の圧縮流体貯蔵装置により発電手段の発電機１を補助するアシストモード、エネルギー貯蔵手段の圧縮流体貯蔵装置を休止する休止モードを選択し、発電機１と圧縮流体貯蔵装置の使用を制御する。 When operating a vessel such as a container ship, just as with the first example, power is supplied only by the compressed fluid storage device of the energy storage means so as to respond to the power demand during normal navigation, at entry / exit, and cargo handling. A single power supply mode for charging, a filling mode for filling the compressed fluid storage device of the energy storage means, an assist mode for assisting the generator 1 of the power generation means by the compressed fluid storage device of the energy storage means, and a suspension of the compressed fluid storage device of the energy storage means The sleep mode to be selected is selected, and the use of the generator 1 and the compressed fluid storage device is controlled.

具体的には、コンテナ船等の船舶が運航する場合には、図３のフローを参照して、制御部３２により、予め設定された発電機１の負荷率の基準値（％）と、発電機１の実際の負荷率とを比較し（ステップＳ１）、発電機１の実際の負荷率が基準値（％）よりも小さい場合（ステップＳ１のＮＯ）には、予め設定された圧縮流体貯蔵装置の蓄電量の基準値（ｋＷｈ）と、圧縮流体貯蔵装置の実際の蓄電量とを比較する段階（ステップＳ２）へ移行する。そして圧縮流体貯蔵装置の実際の蓄電量を比較する段階（ステップＳ２）では圧縮流体貯蔵装置の実際の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ２のＹＥＳ）に、単独給電モードに移行する（ステップＳ３）。 Specifically, when a vessel such as a container ship operates, the control unit 32 refers to the preset load factor reference value (%) and the power generation with reference to the flow of FIG. The actual load factor of the generator 1 is compared (step S1). If the actual load factor of the generator 1 is smaller than the reference value (%) (NO in step S1), the preset compressed fluid storage The process proceeds to a step (step S2) of comparing the reference value (kWh) of the storage amount of the device with the actual storage amount of the compressed fluid storage device. In the stage of comparing the actual charged amount of the compressed fluid storage device (step S2), when the actual charged amount of the compressed fluid storage device is larger than the reference value (kWh) (YES in step S2), the single power supply mode is set. Transition is made (step S3).

単独給電モード（ステップＳ３）では制御部３２から切替手段１７，３７ａ，４０，４２，４４に制御信号を送り、第一の給電側切替手段１７の切替により第一給電回路１８を遮断して発電機１を停止し、また第四の給電側切替手段４２の切替により第四給電回路４３を接続し、圧縮流体貯蔵装置の電力のみを第一電力消費系統１１へ給電する。 In the single power supply mode (step S3), a control signal is sent from the control unit 32 to the switching means 17, 37a, 40, 42, 44, and the first power supply circuit 18 is cut off by switching the first power supply side switching means 17 to generate power. The machine 1 is stopped and the fourth feeding circuit 43 is connected by switching the fourth feeding side switching means 42 to feed only the power of the compressed fluid storage device to the first power consumption system 11.

一方、制御部３２では、単独給電モード（ステップＳ３）であっても、常に、予め設定された圧縮流体貯蔵装置の蓄電量の基準値（ｋＷｈ）と、圧縮流体貯蔵装置の現状の蓄電量とを比較しており（ステップＳ４）、圧縮流体貯蔵装置の現状の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ４のＮＯ）には単独給電モードを維持し（ステップＳ３）、圧縮流体貯蔵装置の現状の蓄電量が基準値（ｋＷｈ）より小さい場合（ステップＳ４のＹＥＳ）には、制御部３２は発電機１を始動し、第一の給電側切替手段１７の切替により第一給電回路１８を接続して単独給電モードを終了し（ステップＳ５）、最初の段階へ移行する。ここで図３の符号Ａは最初の段階へ戻ることを示している。 On the other hand, in the control unit 32, even in the single power supply mode (step S3), the preset reference value (kWh) of the charged amount of the compressed fluid storage device and the current charged amount of the compressed fluid storage device are always set. (Step S4), and when the current charged amount of the compressed fluid storage device is larger than the reference value (kWh) (NO in step S4), the single power supply mode is maintained (step S3). When the current storage amount of the storage device is smaller than the reference value (kWh) (YES in step S4), the control unit 32 starts the generator 1 and switches the first power feeding side switching means 17 to the first power feeding. The circuit 18 is connected to end the single power supply mode (step S5), and the process proceeds to the first stage. Here, the symbol A in FIG. 3 indicates that the process returns to the first stage.

次に、制御部３２により、予め設定された圧縮流体貯蔵装置の蓄電量の基準値（ｋＷｈ）と、圧縮流体貯蔵装置の実際の蓄電量とを比較する段階（ステップＳ２）で、圧縮流体貯蔵装置の実際の蓄電量が基準値（ｋＷｈ）よりも小さい場合（ステップＳ２のＮＯ）には充填モードに移行する（ステップＳ６）。 Next, the control unit 32 compares the preset reference value (kWh) of the charged amount of the compressed fluid storage device with the actual charged amount of the compressed fluid storage device (step S2), and stores the compressed fluid. When the actual power storage amount of the apparatus is smaller than the reference value (kWh) (NO in step S2), the charging mode is shifted (step S6).

充填モード（ステップＳ６）では制御部３２から切替手段３７ａ，４０，４２，４４に制御信号を送り、第四切替手段４０の切替により第四回路４１を接続すると共に第四の給電側切替手段４２の切替により第四給電回路４３を接続し、発電機１の電力を回収して圧縮流体貯蔵装置へ充填する。また充填モードでは、発電機１の電力を第一電力消費系統１１へ給電する。 In the filling mode (step S6), a control signal is sent from the control unit 32 to the switching means 37a, 40, 42, 44, the fourth circuit 41 is connected by switching the fourth switching means 40, and the fourth power supply side switching means 42 is connected. The fourth power feeding circuit 43 is connected by switching, and the electric power of the generator 1 is recovered and filled into the compressed fluid storage device. In the filling mode, the power of the generator 1 is supplied to the first power consumption system 11.

一方、制御部３２では、充填モード（ステップＳ６）であっても、常に、予め設定された圧縮流体貯蔵装置の蓄電量の基準値（ｋＷｈ）と、圧縮流体貯蔵装置の現状の蓄電量とを比較しており（ステップＳ７）、圧縮流体貯蔵装置の現状の蓄電量が基準値（ｋＷｈ）よりも小さい場合（ステップＳ７のＮＯ）には充填モードを維持し（ステップＳ６）、圧縮流体貯蔵装置の現状の蓄電量が基準値（ｋＷｈ）より大きい場合（ステップＳ７のＹＥＳ）には充填モードを終了し（ステップＳ８）、最初の段階へ移行する。 On the other hand, the control unit 32 always sets the preset reference value (kWh) of the charged amount of the compressed fluid storage device and the current charged amount of the compressed fluid storage device even in the filling mode (step S6). When the current storage amount of the compressed fluid storage device is smaller than the reference value (kWh) (NO in step S7), the filling mode is maintained (step S6), and the compressed fluid storage device is compared. Is greater than the reference value (kWh) (YES in step S7), the charging mode is terminated (step S8), and the process proceeds to the first stage.

続いて、制御部３２により、予め設定された発電機１の負荷率の基準値（％）と、発電機１の実際の負荷率とを比較する段階（ステップＳ１）で、発電機１の実際の負荷率が基準値（％）よりも大きい場合（ステップＳ１のＹＥＳ）には、予め設定された圧縮流体貯蔵装置の蓄電量の基準値（ｋＷｈ）と、圧縮流体貯蔵装置の実際の蓄電量とを比較する段階（ステップＳ９）へ移行する。そして圧縮流体貯蔵装置の実際の蓄電量を比較する段階（ステップＳ９）では圧縮流体貯蔵装置の実際の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ９のＹＥＳ）に、アシストモードに移行する（ステップＳ１０）。 Subsequently, the control unit 32 compares the preset reference value (%) of the load factor of the generator 1 with the actual load factor of the generator 1 (step S1). Is greater than the reference value (%) (YES in step S1), the preset reference value (kWh) of the charged amount of the compressed fluid storage device and the actual charged amount of the compressed fluid storage device The process proceeds to the step of comparing (step S9). Then, in the stage of comparing the actual charged amount of the compressed fluid storage device (step S9), when the actual charged amount of the compressed fluid storage device is larger than the reference value (kWh) (YES in step S9), the mode shifts to the assist mode. (Step S10).

アシストモード（ステップＳ１０）では制御部３２から切替手段３７ａ，４０，４２，４４に制御信号を送り、第四の給電側切替手段４２の切替により第四給電回路４３を接続し、圧縮流体貯蔵装置により発電機１の給電を補助し、第一電力消費系統１１、第二電力消費系統１２、第三電力消費系統１５へ給電し、最大電力に対応する。これによりアシストモードは、発電機１及び圧縮流体貯蔵装置を並列で用いてバウスラスタ等の船舶の補助推進手段を駆動する状態になる。 In the assist mode (step S10), a control signal is sent from the control unit 32 to the switching means 37a, 40, 42, 44, and the fourth power feeding circuit 43 is connected by switching the fourth power feeding side switching means 42, and the compressed fluid storage device Thus, the power supply of the generator 1 is assisted, the power is supplied to the first power consumption system 11, the second power consumption system 12, and the third power consumption system 15 to correspond to the maximum power. As a result, the assist mode is a state in which the auxiliary propulsion means of the ship such as a bow thruster is driven using the generator 1 and the compressed fluid storage device in parallel.

ここで、単独給電モード、充填モード、アシストモードのいずれも、圧縮流体貯蔵装置から冷凍コンテナの第二電力消費系統１２へ給電する場合には、冷凍コンテナの搭載量に応じて、適宜、第五の給電側切替手段４４の切替により第五給電回路４５を遮断または接続することも可能である。 Here, in any of the single power supply mode, the charging mode, and the assist mode, when power is supplied from the compressed fluid storage device to the second power consumption system 12 of the refrigerated container, the fifth power supply is appropriately selected according to the amount of the refrigerated container mounted. The fifth power feeding circuit 45 can be cut off or connected by switching the power feeding side switching means 44.

一方、制御部３２では、アシストモード（ステップＳ１０）であっても、常に、予め設定された圧縮流体貯蔵装置の蓄電量の基準値（ｋＷｈ）と、圧縮流体貯蔵装置の現状の蓄電量とを比較しており（ステップＳ１１）、圧縮流体貯蔵装置の現状の蓄電量が基準値（ｋＷｈ）よりも大きい場合（ステップＳ１１のＮＯ）にはアシストモードを維持し（ステップＳ１１）、圧縮流体貯蔵装置の現状の蓄電量が基準値（ｋＷｈ）より小さい場合（ステップＳ１１のＹＥＳ）にはアシストモードを終了し（ステップＳ１２）、最初の段階へ移行する。 On the other hand, in the control unit 32, even in the assist mode (step S10), the preset reference value (kWh) of the charged amount of the compressed fluid storage device and the current charged amount of the compressed fluid storage device are always set. When the current storage amount of the compressed fluid storage device is larger than the reference value (kWh) (NO in step S11), the assist mode is maintained (step S11), and the compressed fluid storage device is compared. When the current storage amount is smaller than the reference value (kWh) (YES in step S11), the assist mode is ended (step S12), and the process proceeds to the first stage.

更に、制御部３２により、予め設定された圧縮流体貯蔵装置の蓄電量の基準値（ｋＷｈ）と、圧縮流体貯蔵装置の実際の蓄電量とを比較する段階（ステップＳ９）で、圧縮流体貯蔵装置の実際の蓄電量が基準値（ｋＷｈ）よりも小さい場合（ステップＳ９のＮＯ）には休止モードに移行する（ステップＳ１３）。 Further, the controller 32 compares the preset reference value (kWh) of the charged amount of the compressed fluid storage device with the actual charged amount of the compressed fluid storage device (step S9). When the actual amount of electricity stored is smaller than the reference value (kWh) (NO in step S9), the process shifts to the suspension mode (step S13).

休止モード（ステップＳ１３）では制御部３２から切替手段３７ａ，４０，４２，４４に制御信号を送り、第四切替手段４０の切替により第四回路４１を遮断すると共に第四の給電側切替手段４２の切替により第四給電回路４３を遮断し、更に第五の給電側切替手段４４の切替により第五給電回路４５を遮断し、圧縮流体貯蔵装置を全ての回路から切り離すと共に発電機１の電力を第一電力消費系統１１等へ給電する。 In the sleep mode (step S13), a control signal is sent from the control unit 32 to the switching means 37a, 40, 42, 44, the fourth circuit 41 is shut off by switching the fourth switching means 40, and the fourth power supply side switching means 42 is switched. Is switched off, and the fifth power feeding circuit 45 is shut off by switching the fifth power feeding side switching means 44, thereby disconnecting the compressed fluid storage device from all the circuits and powering the generator 1. Power is supplied to the first power consumption system 11 and the like.

一方、制御部３２では、休止モード（ステップＳ１３）をそのまま最初の段階へ移行し、再度、単独給電モード、充填モード、アシストモード、休止モードを選択する。 On the other hand, in the control unit 32, the suspension mode (step S13) is shifted to the first stage as it is, and the single power supply mode, the charging mode, the assist mode, and the suspension mode are selected again.

その後、船舶の運航に基づいて単独給電モード、充填モード、アシストモード、休止モードの選択を繰り返して発電機１及び圧縮流体貯蔵装置を連続的に制御することが可能となる。ここで、単独給電モード、充填モード、アシストモード、休止モードの選択は、他の制御に基づくものでも良く、更に制御部３２には、発電機１や圧縮流体貯蔵装置の給電を人為的に停止する緊急停止モードや、発電機１や圧縮流体貯蔵装置の給電を人為的に変更する変更モードを備えても良く、特に条件が制限されるものではない。 Thereafter, the generator 1 and the compressed fluid storage device can be continuously controlled by repeatedly selecting the single power supply mode, the filling mode, the assist mode, and the pause mode based on the operation of the ship. Here, the selection of the single power supply mode, the filling mode, the assist mode, and the sleep mode may be based on other controls, and the control unit 32 artificially stops power supply to the generator 1 and the compressed fluid storage device. There may be provided an emergency stop mode, and a change mode for artificially changing the power supply of the generator 1 or the compressed fluid storage device, and the conditions are not particularly limited.

而して、このように実施の形態の第二例によれば、第一例と略同様な作用効果を得ることができる。また実施の形態の第二例において、エネルギー貯蔵手段は圧縮流体貯蔵装置であると、装置の軽量化を為し得るので、圧縮流体貯蔵装置を適切に設置し、発電機１の発電容量を容易に小さくしてエネルギー効率を高めることができる。 Thus, according to the second example of the embodiment as described above, it is possible to obtain substantially the same effect as the first example. In the second example of the embodiment, if the energy storage means is a compressed fluid storage device, the device can be reduced in weight. Therefore, the compressed fluid storage device is appropriately installed, and the power generation capacity of the generator 1 can be easily achieved. The energy efficiency can be increased by reducing the size.

更に、本発明の実施の形態の第三例として、第一例及び第二例のエネルギー貯蔵手段の構成を、波力発電装置を用いたシステムに変更することもできる。 Furthermore, as a third example of the embodiment of the present invention, the configuration of the energy storage means of the first example and the second example can be changed to a system using a wave power generation device.

波力発電装置は、波または船体運動で作り出される船体に作用する水圧を利用して発電する装置であり、例えば波により室内の空気を圧縮する空気室と、空気室に接続された正圧水弁室及び負圧水弁室と、正圧水弁室に接続される正圧集合ダクトと、負圧水弁室に接続される負圧集合ダクトと、正圧集合ダクト及び負圧集合ダクトに接続されるタービン発電機とを備えている。 A wave power generation device is a device that generates power using water pressure acting on a hull created by waves or ship motion, for example, an air chamber that compresses indoor air by waves, and a positive pressure water connected to the air chamber. A valve chamber and a negative pressure water valve chamber, a positive pressure collecting duct connected to the positive pressure water valve chamber, a negative pressure collecting duct connected to the negative pressure water valve chamber, a positive pressure collecting duct and a negative pressure collecting duct; And a connected turbine generator.

このような波力発電装置において、寄せ波や船体運動によって水圧が上昇した場合には、空気室の空気を圧縮し、圧縮空気は正圧水弁室及び正圧集合ダクトを介してタービン発電機に流入し、タービン発電機を駆動して大気へ排出される。逆に引き波や船体運動によって空気室の水圧が減じた場合には、空気室の空気を膨張させて負圧にし、負圧空気は、負圧水弁室及び正負集合ダクトを介して、大気から空気を引き込みタービン発電機を駆動する。これにより、タービン発電機を駆動して発電する。 In such a wave power generation device, when the water pressure rises due to a spilling wave or hull motion, the air in the air chamber is compressed, and the compressed air passes through the positive pressure water valve chamber and the positive pressure collecting duct and is a turbine generator. Is discharged to the atmosphere by driving the turbine generator. Conversely, when the water pressure in the air chamber decreases due to pulling waves or hull motion, the air in the air chamber is expanded to a negative pressure, and the negative pressure air passes through the negative pressure water valve chamber and the positive and negative collecting duct to the atmosphere. Air is drawn in from the turbine to drive the turbine generator. Thus, the turbine generator is driven to generate power.

このような波力発電装置を用いた場合には、第一例または第二例と略同様に制御され、第一例または第二例と略同様な作用効果を得ることができる。 When such a wave power generation device is used, it is controlled in substantially the same manner as in the first example or the second example, and it is possible to obtain substantially the same effect as in the first example or the second example.

尚、本発明の船舶の電力設備及びその運用方法は、上述の形態例にのみ限定されるものではなく、他の制御方法や他の基準値を用いて発電手段とエネルギー貯蔵手段を制御しても良いこと、エネルギー貯蔵手段手段は、太陽発電や風力発電の如く自然界のエネルギーを用いるものでなく、発電手段からエネルギーを回収するものならば、静電容量装置に代表される電気エネルギーの貯蔵手段、フライホイール等の電気以外の物理エネルギーの貯蔵装置の他の構成や方法でも良いこと、その他、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。 In addition, the power equipment of the ship of this invention and its operation method are not limited only to the above-mentioned form example, Control a power generation means and an energy storage means using another control method or another reference value. In addition, the energy storage means means does not use natural energy such as solar power generation or wind power generation, but can recover electrical energy from the power generation means. Of course, other configurations and methods of storage devices for physical energy other than electricity, such as flywheels, may be used, and various changes can be made without departing from the scope of the present invention.
