Description
塔:高さ80m、直径6〜8m。
予想消費電力:6.5kW
羽根先端の線速度:150km/h
羽根:幅5m、長さ66m
固定回転速度:6rpm
タービンの羽根のうち3つは、羽根先端から60mの長さの表面を用いて作製されている。
他の3つの羽根は、羽根先端から46mの長さの表面を用いて作製されている。
羽根の表面は、図1に示すように、折り畳むこと及び広げることが可能である。
定格風速:16m/s
タービンが動作を停止して羽根面が折り畳まれるカットアウト速度:25m/s
風力タービンの電力の計算について関数を適用する際に、次のパラメータを選択する:k=1;j=1;Cx=1.32
羽根先端の最大迎角:αd=88°48’
風速が1m/s減少すると、この迎角は26’増加する。
風速が1m/s増加すると、この迎角は26’減少する。
風速が定格風速を超えると、風力タービンの電力が定格レベルで安定するように迎角が減少し続ける。
始動速度:4m/s
風力タービンが強制的に停止される最低風速:3m/s
定格風速での風力タービン出力:P16=1254KW。
発電機容量:1.500KW
定格風速16m/sにおける最大軸推力:323KN
