Abstract
Description
本実施形態の風力発電装置1の起動手順において重要な点の一つは、主軸受12自身の動作による発熱を用いて、主軸受12を加熱する点である。主軸受12は、内輪及び転動体の回転ロスによって発熱するのに加え、主軸受12の潤滑油を密封するオイルシールが主軸11と摺動することによっても発熱する。本実施形態では、風力発電装置1の起動シーケンスの実行中に主軸11を低速で回転させて主軸受12に発熱を起こさせ、これにより、主軸受12を加熱する。主軸受12の温度が十分に上昇した後で主軸受潤滑油ポンプ22を動作させることにより、潤滑油が主軸受12によって冷却されて粘度が上昇することによる排出性の低下の問題を解消することができる。
