Description

本願発明は、風の有無、強弱に関係なく発電が平坦に途切れなく行うことができる風力発電装置に関する。   The present invention relates to a wind turbine generator that can perform power generation flatly and seamlessly regardless of the presence or absence of wind and strength.

従来の風力発電は、風車の回転を回転調節装置（ディスクブレーキ）と回転伝達装置を介して発電機のロータに伝えて発電する方法である。
この方法は、風の強さによる回転数の調節をディスクブレーキにより行って強風時と弱風時における発生電力の差を克服することが行われている。
この方法は、有効な蓄電技術が存在しないことや、強風続きでブレーキをかけすぎてディスクブレーキの発熱に起因して火災が発生すること、台風のような強風時には回転伝達系を切断して発電停止する、又、無風時にも発電停止する、といった問題点がある。現状では、平坦で無停止発電が非常に困難である。
風車で発電機を駆動する以外の方法としては例えば下記のものがある。
特開２００３−２７８６４０号公報 特開２００２−０７０７１９号公報 特開平１１−３５１１２５号公報 特開平１１−３５１１１８号公報 Conventional wind power generation is a method of generating electric power by transmitting rotation of a windmill to a rotor of a generator via a rotation adjusting device (disc brake) and a rotation transmission device.
In this method, the rotational speed is adjusted by the strength of the wind by means of a disc brake to overcome the difference in generated power between the strong wind and the weak wind.
This method is based on the fact that there is no effective power storage technology, the brakes are applied too much with strong winds and a fire occurs due to the heat generated by the disc brakes, and the rotation transmission system is cut off in the case of strong winds such as typhoons. There are problems such as stopping and power generation stop even when there is no wind. At present, flat and non-stop power generation is very difficult.
Examples of methods other than driving the generator with a windmill include the following.

図１に戻り説明する。エアコンプレッサ５は、風車２で風力から得る回転エネルギーを回転伝達機構３、クラッチ４を介して伝達され駆動され高圧気体を一次側高圧気体給送管１０を介して圧力タンク６に溜めて蓄圧する。

By opening and closing the on-off valve in the required order, the working liquid of one gas pressurization type hydraulic cylinder in which the working liquid is stored is fed to the hydraulic motor 8 by pressurizing action to the high pressure gas. Therefore, the hydraulic motor 8 is driven by feeding the working liquid, and the generator 9 is driven by the hydraulic motor 8 to generate electric power.
When the discharge of the working liquid of one gas pressurization type hydraulic cylinder is completed, the supply of the working liquid for driving the hydraulic motor 8 is switched to another gas in which the working liquid is stored by switching the on-off valve. Switching to the pressurized hydraulic cylinder continues to supply the working liquid to the hydraulic motor 8 to continue the power generation of the generator 9, and to the high pressure relative to the one gas pressurized hydraulic cylinder discharged from the working liquid. The working liquid is stored by letting the gas escape, and the high pressure gas is supplied again from the pressure tank 6 after the storage.

図示しない制御装置によって、クラッチ４、高圧気体用自動開閉弁１３ａ,１３ｂ,１３ｃ、高圧気体大気放出用自動開閉弁１６ａ,１６ｂ,１６ｃ、送り側自動開閉弁１８、戻り側自動開閉弁２０、センサ２１ａ,２１ｂ、２２ａ,２２ｂ、２３ａ,２３ｂが制御される。
クラッチ４は、台風時のような強すぎる風があるときには、接続を解除するように制御される。
センサ２１ａ,２１ｂ、２２ａ,２２ｂ、２３ａ,２３ｂの信号は、自動弁の順次の切り替え制御に使用される。 By a control device (not shown), the clutch 4, the high-pressure gas automatic open / close valves 13a, 13b, 13c, the high-pressure gas atmospheric release automatic open / close valves 16a, 16b, 16c, the feed-side automatic open / close valve 18, the return-side automatic open / close valve 20, 21a, 21b, 22a, 22b, 23a, 23b are controlled.

The signals of the sensors 21a, 21b, 22a, 22b, 23a, 23b are used for sequential switching control of the automatic valves.

気体加圧型液圧シリンダを７ａ―７ｂ―７ｃの順で作動液を液圧モータ８に供給する場合の制御について以下に説明する。
（１）今、作動液体の充填されている状態を次ぎのように設定する。気体加圧型液圧シリンダ７ａ,７ｂの大径シリンダ室７１に作動液体が一杯に貯留され、ピストン７３が大径シリンダ室７１の上限位置にあるものとする一方、気体加圧型液圧シリンダ７ｃの大径シリンダ室７１に作動液体が貯留されておらず、ピストン７３が大径シリンダ室７１の下限位置にあるものとする。
（２）制御器は、一番最初、弁１３ａ,１３ｂ,１６ｃを「開」、弁１３ｃ, 弁１６ａ,１６ｂを「閉」にするとともに、弁１８ａ,２０ｃを「開」、弁１８ｂ,１８ｃ, ２０ａ,２０ｂを「閉」にして、クラッチ４を接続する。すると、圧力タンク６から高圧気体が二次側高圧気体給送管１１を通して気体加圧型液圧シリンダ７ａ,７ｂに送られるから、気体加圧型液圧シリンダ７ａの作動液体が液圧モータ８へ給送される。液圧モータ８を通った作動液体は、気体加圧型液圧シリンダ７ｃに流入してピストン７３が持ち上がっていき、エアが弁１６ｃから放出される。気体加圧型液圧シリンダ７ａのピストン７３が下限位置に来ると、気体加圧型液圧シリンダ７ｃのピストン７３が上限位置に来るようになっていて、それぞれセンサ２１ｂ、２３ａにより検出される。
（３）次ぎに、制御器は、弁１３ａを「閉」に、弁１６ａを「開」に、弁２０ａを「開」に、弁１８ｂを「開」に、弁１６ｃを「閉」に、弁１３ｃを「開」に、弁２０ｃを「閉」にする。すると、気体加圧型液圧シリンダ７ｂの作動液体が液圧モータ８へ給送される。液圧モータ８を通った作動液体は、気体加圧型液圧シリンダ７ａに流入してピストン７３が持ち上がっていき、エアが弁１６ａから放出される。気体加圧型液圧シリンダ７ｂのピストン７３が下限位置に来ると、気体加圧型液圧シリンダ７aのピストン７３が上限位置に来るようになっていて、それぞれセンサ２２ｂ、２１ａにより検出される。
（４）次ぎに、制御器は、弁１３ｂを「閉」に、弁１６ｂを「開」に、弁２０ｂを「開」に、弁１８ｃを「開」に、弁１６aを「閉」に、弁１３ａを「開」に、弁２０ａを「閉」にする。すると、気体加圧型液圧シリンダ７ｃの作動液体が液圧モータ８へ給送される。液圧モータ８を通った作動液体は、気体加圧型液圧シリンダ７ｂに流入してピストン７３が持ち上がっていき、エアが弁１６ｂから放出される。気体加圧型液圧シリンダ７ｃのピストン７３が下限位置に来ると、気体加圧型液圧シリンダ７ｂのピストン７３が上限位置に来るようになっていて、それぞれセンサ２３ｂ、２２ａにより検出される。
以後も、制御器は、上記の動作順になるように制御する。
なお、上記の開閉弁１８ａ,１８ｂ,１８ｃの開閉のタイミングについて、同時にいずれも開となる時間が数秒あってもパスカルの定理から、液圧モータ８へ給送される高圧気体の液圧は変化しない。 The control in the case of supplying the hydraulic fluid to the hydraulic motor 8 in the order of the gas pressure type hydraulic cylinder in the order of 7a-7b-7c will be described below.
(1) The state where the working liquid is filled is set as follows. It is assumed that the working liquid is fully stored in the large-diameter cylinder chambers 71 of the gas-pressurized hydraulic cylinders 7a and 7b and the piston 73 is at the upper limit position of the large-diameter cylinder chamber 71.

Then, since the high pressure gas is sent from the pressure tank 6 to the gas pressurization hydraulic cylinders 7 a and 7 b through the secondary high pressure gas feed pipe 11, the working liquid in the gas pressurization hydraulic cylinder 7 a is supplied to the hydraulic motor 8. Sent. The working liquid that has passed through the hydraulic motor 8 flows into the gas pressurizing hydraulic cylinder 7c, the piston 73 is lifted, and air is released from the valve 16c.

(3) Next, the controller sets the valve 13a to “closed”, the valve 16a to “open”, the valve 20a to “open”, the valve 18b to “open”, and the valve 16c to “closed”. The valve 13c is set to “open” and the valve 20c is set to “closed”. Then, the working liquid in the gas pressurization type hydraulic cylinder 7 b is fed to the hydraulic motor 8. The working liquid that has passed through the hydraulic motor 8 flows into the gas pressurizing hydraulic cylinder 7a, the piston 73 is lifted, and air is released from the valve 16a. When the piston 73 of the gas pressurization type hydraulic cylinder 7b comes to the lower limit position, the piston 73 of the gas pressurization type hydraulic cylinder 7a comes to the upper limit position and is detected by the sensors 22b and 21a, respectively.
(4) Next, the controller sets the valve 13b to “closed”, the valve 16b to “open”, the valve 20b to “open”, the valve 18c to “open”, and the valve 16a to “closed”.

The working liquid that has passed through the hydraulic motor 8 flows into the gas pressurizing hydraulic cylinder 7b, the piston 73 is lifted, and air is released from the valve 16b. When the piston 73 of the gas pressurization type hydraulic cylinder 7c comes to the lower limit position, the piston 73 of the gas pressurization type hydraulic cylinder 7b comes to the upper limit position and is detected by the sensors 23b and 22a, respectively.
Thereafter, the controller performs control so that the operation order is as described above.
Note that the hydraulic pressure of the high-pressure gas supplied to the hydraulic motor 8 changes from Pascal's theorem, even if the opening / closing timing of the on-off valves 18a, 18b, 18c is simultaneously several seconds. do not do.

風車２はタワー１に設けられていることに限定しない。風車２とエアコンプレッサ５はクラッチ４を介して直結されていても良い。気体加圧型液圧シリンダは２本あれば足りる。風車２とエアコンプレッサ５と気体加圧型液圧シリンダ７ａを一組として二組備えていて、２本の気体加圧型液圧シリンダの高圧気体が切り替え式に液圧モータ８に給送されるようになっていても良い。液圧モータ８は、ギヤ型、ベーン型、ピストン型のいずれであっても良い。設備の配列について、エアコンプレッサ５と液圧モータ８と発電機９を集合して配置し、気体加圧型液圧シリンダ７ａ,７ｂ,７ｃを抱き合わせて配置すると、配管がコンパクトになる。   The windmill 2 is not limited to being provided in the tower 1.
