Description
また、この種の風力発電装置では、風力エネルギーを最大限に活用するため、ナセル上部に風向計を設置し、この風向計により検出される主風向に対してナセルが正面を向くように方位制御するようになっている。
本発明は、風向に追従してナセルの向きを可変制御する風力発電装置であって、主風向を検出する風向検出手段と、所定の風速における前記主風向と実際の風向である実風向とのずれである風向オフセット値を仮定することにより実風向を仮定する風向仮定手段と、前記仮定された実風向における所定時間の平均発電出力を算出する平均発電出力算出手段と、前記仮定された風向オフセット値に対する前記平均発電出力を二次曲線に近似し、該近似した二次曲線における前記平均発電出力が最大となるときの風向オフセット値を、実際のオフセット値と推定することにより実風向を推定する実風向推定手段と、を備えたことを特徴とする風力発電装置を提供する。
図1は、本発明に係る風力発電装置の概略構成を示したブロック図である。図1に示すように風力発電装置は、ナセル10上部に風向検出手段としての風向計11を備え、この風向計が風力発電装置に当たる風の向きを検出し、検出した風向を演算部20に出力する。
次に、本発明の第2の実施形態について、図6、図7を用いて説明する。
本実施形態の風力発電装置は第1の実施形態とその構成を同一にするが、風向推定方法の処理手順が異なる。上述した第1の実施形態は、近似式を求めることにより二次の近似曲線を生成したが、本実施の形態では、勾配法を用いて近似曲線を生成する処理について説明する。図6は、本実施の形態に係る風向推定方法の処理手順を示すフローチャートである。なお、以下に述べる本処理手順においても、予め風向オフセット値WOを推定する対象速度Vaを定め、この速度Vaにおける平均発電出力を算出する。
