Abstract
【解決手段】風力タービン(10)は、タワー(18)と、タワー(18)の上端部に支持されたナセル(16)と、少なくとも1つのブレード(14)を有しかつナセル(16)に配置されたロータ(12)と、タワー(18)又はナセル(16)のいずれかに配置された振動荷重低減システム(20)とを含む。振動荷重低減システム(20)は、ベース(24)と、ベース(24)から延びる少なくとも2つのカラム(22)と、ベース(24)及び少なくとも2つのカラム(22)内部に設置された流動性質量(28)とを含む。
【選択図】 図1
Description
ΔωS=タワー18の固有振動数の変化、
g=重力加速度、及び、
Δl=カラム22の垂直長さに2を乗じ、ベース24の水平長さを加えた振動システムの全長の変化。
a1は、正弦波信号の第1番目のピークの振幅であり、
anは、正弦波信号の第n番目のピークの振幅である。
g=重力加速度、及び、
ωS=2πfT=ラジアン/秒で表した風力タービンシステムの第1の固有振動数。
fT=Hzで表わした風力タービンシステムの第1の固有振動数。
le=振動数計算における等価全長
D=ベースリング中心直径
AH=水平リング面積
LV=垂直カラム高さ
AV=垂直カラム面積
ξ=水頭損失係数
ρ=液体密度
特に振動荷重低減システムをタワー18又はナセル16の内部に据付けた場合には、ベースリング24の外径Dは、タワーの幾何学的形状によって決定することができる。カラム22とベースリング24との間の断面積比AV/AHは、タワー上端部又はナセル内部の垂直方向スペース限界に基づいて選定することができる。良好な開始点は、垂直高さを残しておくように2:1を使用して、システムを可能な限り高い位置に配置して有効性の利点を得るようにすることができる。そこで、垂直水カラム高さLVは、次式のように計算することができる。
MWTG=ロータブレード14、ハブ15及びナセル16の総重量、
ρ=水の密度
上記で説明したように、カラム22の配向はまた、振動荷重低減システム20の矩形配向又は振動荷重低減システムの円形配向のいずれかを有することよっても変化させることができる。据付けを容易にするために、システムの形状は、ナセル16又はタワー18のいずれかにおける振動荷重低減システム20の設置場所により決まることになる。加えて、カラムの数及び配置は、風力タービンの基本振動数により決まる。
質量比μ=1.5%
風力タービン10の上端部質量=MWTG=Mナセル+ロータ=82200kg
振動荷重低減システム20の質量=Mダンパ=0.015*(82200kg)=1233kg
タワー直径=4メートル
よって、ベースリング中心直径D=3.8メートル
風力タービンの第1の曲げ振動数=0.265Hz
よって、振動荷重低減システムの等価長さは、
次に垂直水カラム高さは、下記になる。
質量比μ=5%
風力タービン10の上端部質量=MWTG=Mナセル+ロータ=82200kg
振動荷重低減システム20の質量=Mダンパ=0.05*(82200kg)=4110kg
タワー直径=4メートル
よって、ベースリング中心直径D=3.8メートル
風力タービンの第1の曲げ振動数fT=0.265Hz
よって、振動荷重低減システムの等価長さは、
次に垂直水カラム高さは、下記になる。
12 ロータ
14 ブレード
15 ハブ
16 ナセル
18 タワー
20 振動荷重低減システム
22 カラム
24 ベース
26 バルブ
28 流動性質量
