Description
【発明の詳細な説明】 この発明は風車に関するものである。[Detailed description of the invention] This invention relates to a windmill.
自然風から風力エネルギーを取り出すための風車は、石
油代替エネルギー開発の要請から、その実用化が推進さ
れている。The practical application of wind turbines for extracting wind energy from natural wind is being promoted due to the need to develop alternative energy to oil.
風車の実用化を図る」−で゛の問題点の一つは、定格出
力運転の範囲を大きくすること、及び突風時の風車の破
損を回避することである。One of the problems with "Practical Application of Wind Turbines" is to widen the range of rated output operation and to avoid damage to the wind turbine during gusts of wind.
風車のノマワーPは、ρ:空気の密度、U〜:風速、η
:効率、A:受風面積とすると、
P=1/2・ρ・U3←〜・η・A ・・・・・
・(1)で与えられる。The wind turbine power P is: ρ: air density, U: wind speed, η
: efficiency, A: swept area, then P=1/2・ρ・U3←〜・η・A ・・・・・
・Given by (1).
風車を使用した発電装置によって発電し、その電力を系
統電力網に給電する場合には、系統電力の品質を保つた
めに風車の定格出力運転を要求されることが多い。When generating electricity using a power generation device using a wind turbine and feeding the generated power to a power grid, the wind turbine is often required to operate at its rated output in order to maintain the quality of the grid power.
このような運転モードの一例は第1図に示すように、風
速U1以上で起動回転するが、定格出力PRを得る定格
風速URに達するまでは出力を系統電力網に接続せず、
風速UR−U2の間でのみ一定出力を給電する。As shown in Fig. 1, an example of such an operation mode is that the starting rotation is performed at a wind speed of U1 or more, but the output is not connected to the grid power grid until the rated wind speed UR is reached to obtain the rated output PR.
A constant output is supplied only between wind speeds UR and U2.
しかるに、我国では比較的に平均風速が低く、定格出力
運転に必要な風速範囲が狭くなっているが、(1)式か
ら明らかな通り、風車の受風面積を大きくすれば、定格
出力を得るために必要な風速は小さくてもよいことにな
り、密度の低い風jEも有効に活用することができるこ
ととなり、このことは平均風速が低い気候を持つ地域に
おける風力エネルギーの利用上きわめて有利である。However, in Japan, the average wind speed is relatively low and the wind speed range required for rated output operation is narrow, but as is clear from equation (1), if the wind turbine area is increased, the rated output can be achieved. This means that the wind speed required for this purpose can be small, and even low-density wind jE can be used effectively, which is extremely advantageous for the use of wind energy in regions with climates where the average wind speed is low. .
このようなことから、風車の受風面積を増加させ得る風
車が望まれる。For this reason, a wind turbine that can increase the area of the wind turbine that receives wind is desired.
一方、台風時の如く突風が吹く場合には、その突風が風
車に当って風車を破損させる事故が生ずることがあり、
その対策が必要である。On the other hand, when gusts of wind blow, such as during a typhoon, the gusts can hit windmills and cause accidents that damage them.
Countermeasures are necessary.
その対策の一つとしては、台風時にのみ風車の受風面積
を縮少することが有効である。One of the effective countermeasures is to reduce the wind turbine area only during typhoons.
このように、受風面積の大小を必要に応じて調整し得る
風車が望まれるのであるが、現在まで、この要求を容易
かつ確実に満たずものを得るに至っていない。As described above, there is a desire for a wind turbine that can adjust the size of the wind blowing area as necessary, but to date, no wind turbine has been able to easily and reliably satisfy this requirement.
この発明は上記の如き事情に鑑みてなされたものであっ
て、定格運転時に受風面積を風強に応じて容易にかつ確
実に調整することができる垂直回転軸型風車を提供する
ことを目的とするものである。This invention was made in view of the above circumstances, and an object of the present invention is to provide a vertical rotating shaft type wind turbine that can easily and reliably adjust the receiving area according to the wind strength during rated operation. That is.
