水素発生装置として使用する水電解装置は入力電圧変動に弱い一方、風力発電は、不安定な風力を動力源として発電する分散型発電であり、その発電出力は風力の変化により大きく変動する性格を有するものである。したがって、これをそのまま水電解装置の入力電源とした場合には、水電解装置の寿命低下を招くことになる。   While water electrolysis devices used as hydrogen generators are vulnerable to fluctuations in input voltage, wind power generation is a distributed generation that generates power using unstable wind power as a power source, and its power generation output has a tendency to fluctuate greatly due to changes in wind power. It is what you have. Therefore, if this is used as an input power source for the water electrolysis apparatus as it is, the life of the water electrolysis apparatus will be reduced.

本発明はかかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、風力発電による発電出力の変動を抑制して水電解装置の寿命低下を防止することにある。   The present invention has been made to solve such problems. That is, an object of the present invention is to prevent a decrease in the life of a water electrolysis apparatus by suppressing fluctuations in power generation output due to wind power generation.

本発明によれば、風車と同期発電機を備えた風力発電装置と、前記風力発電装置の発電出力を制御する発電出力制御装置と、前記風力発電装置により得られた発電出力を電源として水素を発生させる水電解装置とを備え、前記発電出力制御装置は、前記風力発電装置から取り出す発電出力を所定範囲に制限することにより電圧変動を緩やかにし、前記風力発電装置への入力トルク変動分は、前記風力発電装置自身の慣性モーメントを利用して自身の回転数増減によって吸収し、前記風力発電装置は電力系統へ連係せずに独立で運転される、ことを特徴とする風力発電を利用した水素製造設備が提供される。   According to the present invention, a wind power generator including a windmill and a synchronous generator, a power generation output control device that controls the power generation output of the wind power generation device, and hydrogen generated using the power generation output obtained by the wind power generation device as a power source. A water electrolysis device to generate, the power generation output control device to moderate the voltage fluctuation by limiting the power generation output taken out from the wind power generation device to a predetermined range, the input torque fluctuation to the wind power generation device, Hydrogen using wind power generation, wherein the wind power generation device absorbs by increasing / decreasing its own rotational speed using the moment of inertia of the wind power generation device itself, and the wind power generation device is operated independently without being linked to a power system. Manufacturing equipment is provided.

上記本発明の構成によれば、入力トルク変動分を風車と発電機の回転エネルギーとして吸収するので、風力発電装置からの発電出力は緩やかに変動し、これを水電解装置の電源とすることにより、水電解装置の寿命低下を防止できる。   According to the configuration of the present invention, since the input torque fluctuation is absorbed as the rotational energy of the wind turbine and the generator, the power generation output from the wind power generator fluctuates gently, and this is used as the power source of the water electrolysis device. It is possible to prevent a decrease in the life of the water electrolysis apparatus.

以下、本発明の好ましい実施形態を添付図面に基づいて詳細に説明する。なお、各図において共通する部分には同一の符号を付し、重複した説明を省略する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the same code | symbol is attached | subjected to the common part in each figure, and the overlapping description is abbreviate | omitted.

図１は、本発明の実施形態の概念図である。水素発生設備は、風車１１ａと同期発電機１１ｂを備えた風力発電装置１１と、風力発電装置１１の発電出力を制御する発電出力制御装置１５と、風力発電装置１１により得られた発電出力を交流電力から直流電力に変換する整流器１３と、変換された発電出力を電源として水素を発生させる水電解装置１４とを備えている。また図１に示すように、風力発電装置１１は電力系統へ連係せずに独立で運転される。   FIG. 1 is a conceptual diagram of an embodiment of the present invention. The hydrogen generation facility includes a wind turbine generator 11 provided with a wind turbine 11a and a synchronous generator 11b, a power generation output control device 15 that controls the power generation output of the wind power generator 11, and an AC power generation output obtained by the wind power generator 11. It includes a rectifier 13 that converts electric power into direct-current power, and a water electrolysis device 14 that generates hydrogen using the converted power generation output as a power source. As shown in FIG. 1, the wind power generator 11 is operated independently without being linked to the power system.

通常、風車入力トルク（風速）は短時間の間に激しく変動するものであり、これに伴い風力発電装置１１による発電出力は激しく変動するため、これを直接、水電解装置１４の電源とすると、水電解装置１４の寿命が短くなる。一方、水電解装置１４の入力電圧を一定とすると、風車１１ａの回転可能領域が制限され、風力発電の設備利用率の低下を招く。   Usually, the windmill input torque (wind speed) fluctuates violently in a short time, and the power generation output by the wind power generator 11 fluctuates violently along with this. The life of the water electrolysis device 14 is shortened. On the other hand, if the input voltage of the water electrolysis device 14 is constant, the rotatable region of the windmill 11a is limited, leading to a reduction in the facility utilization rate of wind power generation.

そこで、本発明の風力発電を利用した水素生産設備は、発電出力制御装置１５を備えている。発電出力制御装置１５は、風力発電装置１１から取り出す発電出力を所定範囲に制限することにより電圧変動を緩やかにする。また、発電出力制御装置１５による電圧変動の抑制による風力発電装置への入力トルク変動分は、風力発電装置自身の慣性モーメントを利用して自身の回転数増減によって吸収する。
上記の構成により、風力発電装置１１からの発電出力は緩やかに変動し、これを水電解装置１４の電源とすることにより、水電解装置１４の寿命低下を防止できる。 Therefore, the hydrogen production facility using wind power generation according to the present invention includes a power generation output control device 15. The power generation output control device 15 moderates the voltage fluctuation by limiting the power generation output extracted from the wind power generation device 11 to a predetermined range. Further, the fluctuation of the input torque to the wind turbine generator due to the suppression of the voltage fluctuation by the generator output control device 15 is absorbed by the increase / decrease of its own rotation speed using the inertia moment of the wind turbine generator itself.
With the above configuration, the power generation output from the wind power generator 11 varies gently, and by using this as the power source for the water electrolysis device 14, it is possible to prevent a reduction in the life of the water electrolysis device 14.

図２は、参考例を説明する概念図である。参考例による水素製造設備１０は、風車１１ａと発電機１１ｂと励磁機１１ｃを備えた風力発電装置１１、整流器１３、水電解装置１４を備えており、さらに風車回転数制御装置１６および電圧制御装置１７を備えている。   FIG. 2 is a conceptual diagram illustrating a reference example. The hydrogen production facility 10 according to the reference example includes a wind turbine generator 11 provided with a wind turbine 11a, a generator 11b, and an exciter 11c, a rectifier 13, and a water electrolysis device 14, and further includes a wind turbine speed controller 16 and a voltage controller. 17 is provided.

ここで、図３は、風力発電装置１１における風速（ｍ／ｓ）、風車回転数（ｒｐｍ）および出力電力（ｋＷ）の関係を示した図であり、横軸に風車回転数、縦軸に発電機の出力電力をとり、各風速ごとの出力特性を図中の曲線群で示している。直線Ａは、系統連係している風力発電の運転ラインを示しており、風速が比較的遅いときは、風車回転数をω１とし、風速が比較的早いときは風車回転数をω２としている。一方、曲線Ｂは、風力発電の理論最大出力ラインであり、各風速における最大出力ポイントをつないだものである。この図から分かるように、各風速ごとに最大出力ポイントとなる風車回転数が異なるため、効率良く発電を行うためには、各風速ごとに風車回転数を変化させる必要がある。すなわち、曲線Ｂのライン上で運転を行う必要がある。   Here, FIG. 3 is a diagram showing the relationship between the wind speed (m / s), the windmill rotational speed (rpm), and the output power (kW) in the wind turbine generator 11, where the horizontal axis represents the windmill rotational speed and the vertical axis represents The output power of the generator is taken, and the output characteristics for each wind speed are shown by a group of curves in the figure. A straight line A indicates an operating line of wind power generation that is linked to the grid. When the wind speed is relatively slow, the windmill rotational speed is ω1, and when the wind speed is relatively fast, the windmill rotational speed is ω2. On the other hand, curve B is the theoretical maximum output line of wind power generation, and connects the maximum output points at each wind speed. As can be seen from this figure, since the wind turbine rotation speed, which is the maximum output point, is different for each wind speed, it is necessary to change the wind turbine rotation speed for each wind speed in order to generate power efficiently. That is, it is necessary to operate on the line of curve B.

そこで、参考例では、風力発電装置１１を系統へ連結せず独立で運転することとし、風車付近における風速および風車回転数を風車回転数制御装置１６に入力信号として入力し、風速から最大出力となる最適風車回転数を演算するとともに、この風車回転数となるように風力発電装置１１の励磁機１１ｃの励磁電流を制御して諸望の風車回転数に制御する。   Therefore, in the reference example, the wind power generator 11 is operated independently without being connected to the system, and the wind speed and the wind turbine speed in the vicinity of the wind turbine are input to the wind turbine speed controller 16 as input signals, and the maximum output from the wind speed is obtained. Is calculated, and the exciting current of the exciter 11c of the wind power generator 11 is controlled so as to be the wind turbine rotational speed, thereby controlling the desired wind turbine rotational speed.

このように、風力発電装置１１を独立運転としたことにより、系統連係による設備利用率の低下を解消でき、常に最適効率で発電運転を行い、高効率で水素を製造することが可能となる。   Thus, by making the wind power generator 11 an independent operation, it is possible to eliminate the decrease in the facility utilization rate due to the grid linkage, and it is possible to always perform the power generation operation with the optimum efficiency and produce hydrogen with high efficiency.

電圧制御装置１７は、風力発電装置１１により得られた発電出力の電圧および電解電圧を入力信号として入力し、風車回転数の制御により変動する出力電圧を緩やかに変化させるための電圧指令信号を出力する。例えば、時定数をもたせてゆるやかに変化させることが好ましい。   The voltage control device 17 inputs the voltage of the power generation output and the electrolysis voltage obtained by the wind turbine generator 11 as input signals, and outputs a voltage command signal for gently changing the output voltage that fluctuates by controlling the wind turbine rotation speed. To do. For example, it is preferable to change it slowly with a time constant.

風力発電装置１１により得られた発電出力は整流器１３に送られ交流電力から直流電力に変換され、水電解装置１４に電解電力として供給されるが、最適風車回転数に制御された風力発電装置１１からは、風速の変動に応じてその発電出力が激しく変動することになる。したがって、上述したように、これをそのまま水電解装置１４の電解電力として供給すると水電解装置１４の寿命低下を招く。そこで、この変動の激しい発電出力の電圧を電圧制御装置１７で制御している。これにより、風車回転数制御装置１６により風力発電装置１１で得られた発電出力に変動が生じても、電圧制御装置１７により水電解装置１４への入力電圧の変動を抑制するので、水電解装置１４の寿命低下を防止することができる。   The power generation output obtained by the wind power generator 11 is sent to the rectifier 13, converted from AC power to DC power, and supplied as electrolysis power to the water electrolysis device 14, but the wind power generation device 11 controlled to the optimum wind turbine speed. Therefore, the power generation output fluctuates violently according to the fluctuation of the wind speed. Therefore, as described above, if this is supplied as it is as the electrolysis power of the water electrolysis device 14, the life of the water electrolysis device 14 is reduced. Therefore, the voltage control device 17 controls the voltage of the power generation output that has a large fluctuation. As a result, even if fluctuations occur in the power generation output obtained by the wind turbine generator 11 by the wind turbine rotation speed controller 16, the voltage controller 17 suppresses fluctuations in the input voltage to the water electrolyzer 14, so the water electrolyzer 14 can be prevented from deteriorating.

また、電圧制御装置１７を設けずに、整流器１３のサイリスタの点弧角を調節することにより発電出力の電圧を制御することによっても上記と同様の効果が得られる。   Further, the same effect as described above can be obtained by controlling the voltage of the power generation output by adjusting the firing angle of the thyristor of the rectifier 13 without providing the voltage control device 17.

なお、本発明は上述した実施形態に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。   In addition, this invention is not limited to embodiment mentioned above, Of course, it can change variously in the range which does not deviate from the summary of this invention.
