回転数範囲
ローター 同期機 非同期機
nmin=10 rpm n=1000 rpm nmin=-2000 rpm
nmax=16.5 rpm n=1000 rpm nmax=1500 rpm
回転数の式
nST=72.92・nROTOR−0.1354・nASM
からトルクの式
MSM=MROTOR/72.92 MASM=MROTOR/538.6
を誘導することができる。これより定格回転数及び定格トルクにおける次の出力が得られる。
ローター PR=2000kW (16.5rpm, 1157.5kNm)
同期機 PSM=1662kW (1000rpm, 15.87kNm)
非同期機 PASM=338kW (1500rpm, 2.15kNm)
これは、補助駆動機構7の定格出力は発電所の定格出力のほぼ17%に過ぎず、従って風力発電所から電力配電網内への全体として極めて安定した供給挙動が得られることを示す。
の比較から、パワートレーン減衰のある個別回転翼制御機構が、主に定格負荷範囲においてトルクを明らかにより一様とし、これから対応した負荷の減少を導き、伝導装置、3相機、及び補助駆動機構の設計を最適化させることが示される。
