Description
本発明の第1の態様は、複数の風車翼のピッチ角をそれぞれ独立に制御する独立ピッチ角制御を行う風車のピッチ角制御装置であって、風車停止指令が入力された場合に、各前記風車翼のピッチ角を一致させた後、各前記風車翼のピッチ角をフェザーリング位置に移動させる風車のピッチ角制御装置である。
3 ナセル
5−1,5−2,5−3 風車翼
10 風車のピッチ角制御装置
11−1,11−2,11−3 駆動装置
図1は、本実施形態に係る風車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、風車1は、基礎6の上に立設される支柱2と、支柱2の上端に設置されるナセル3と、略水平な軸線周りに回転可能にしてナセル3に設けられるロータヘッド4とを有している。ロータヘッド4には、その回転軸線周りに放射状に3枚の風車翼5−1,5−2,5−3が取り付けられている。これにより、ロータヘッド4の回転軸線方向から風車翼5−1,5−2,5−3に当たった風の力が、ロータヘッド4を回転軸線周りに回転させる動力に変換され、この動力が発電機によって電気エネルギーに変換されるようになっている。
Memory),ROM(Read
Only Memory),HDD(Hard Disk Drive)などを備えており、CPUがHDD等に格納されている制御プログラムをRAM等に読み出して実行することにより、以下に説明する風車翼のピッチ角制御方法を実現させる。
上記θcomは、共通ピッチ角であり、各風車翼に対して共通の値となる。また、Δθ1,Δθ2,Δθ3は、各風車翼によって決定される調整量であり、例えば、各風車翼に対する荷重や、風速、風向等の風車の運転環境等に応じて決定される。
まず、風車停止指令が入力されると、ピッチ角制御装置10は、風車翼5−1,5−2,5−3の実ピッチ角を比較し、各風車翼のピッチ角が略一致しているか否かを判断する(図3のステップSA1)。具体的には、風車翼のピッチ角を2つずつ比較することにより、ピッチ角の差分を算出し、この差分の最大値が予め設定されている基準値未満であるか否かを判断する。
以下、風車翼5−1が代表風車翼として特定された場合を想定して説明する。
このとき、代表風車翼に対するピッチ角の差分が所定の値以下の風車翼については、調整量に最小調整量ΔθLOWを設定する。このようにすることで、代表風車翼のピッチ角を基準として、ピッチ角がある一定の範囲にある風車翼については、ピッチ角の差分が拡大するのを抑制することができる。
本実施形態では、例えば、最小調整量ΔθLOWは、1(°/s)、最大調整量ΔθHIGHは7(°/s)に設定されている。
そして、各風車翼5−1,5−2,5−3のピッチ角がフェザーリング位置(110°)に一致したところで(図3のステップSA6において「YES」)、本処理を終了する。
