Description
本願は、2006年6月30日に出願された米国出願第11/477,593号及び2006年3月17日に出願された米国仮出願第60/783,029号からの優先権を主張し、上記出願の開示の全体が参照により本明細書に援用される。
概して、本発明の様々な例示的な実施形態による可変速風力タービン発電機は、二次励磁誘導発電機の超同期動作時にロータが発生する電力を励磁機に流す。続いて、励磁機は、この電気エネルギーを機械回転エネルギーに変換し戻し、続いてこのエネルギーを、ステータが発生して系統に送出される電力をさらに増加させるために用いることができる。電力がDFIGのステータによってしか系統に送出されないことで、電力変換器を介した系統への電力の送出が回避される。したがって、系統に供給される電力の品質が改善される。
最適電力追尾コントローラ(OPTC)(303)は、発電機電力を制御するために、DFIGコントローラ(300)によって行われる電力制御ループの電力基準を調整する。この基準は、主調整変数としての測定風速に基づく。
DFIGのステータ有効電力及び無効電力制御は、二次励磁誘導発電機のコントローラ(300)によって行われる。このコントローラは、系統に送出される総電力の優れた調整性能及び制御を提供する。この制御は、以下でさらに詳細に説明するように、系統磁束配向(GFO)を用いて機械の電気パラメータから完全に独立した種々の調整ループに基づく。調整すべき種々の大きさを高精度で測定することにより、二次励磁誘導発電機(205)のステータ(210)によって系統に送出される総電力が完璧に制御され、高品質エネルギーが得られる。
Av_Ps=3/2(Vsd×Isd+Vsq×Isq) 式1
Av_Qs=3/2(Vsq×Isq−Vsd×Isd) 式2
例示的な一実施形態では、可変速システムは、二次励磁誘導発電機(205)を備え、そのロータ(211)は電子電力変換器(222)に接続される。この電子電力変換器は、DCバスシステム(224)を介して第2の電子電力変換器(225)に結合される。一実施形態では、この周波数変換器(電力変換器)(225)は、接触器(228)によって励磁機(212)に接続される。非同期機、DC機、同期(例えば永久磁石)機、又は可逆電気機械等の励磁機は、駆動系に機械的に結合される。
Sp_IEq=バス電圧レギュレータ(607)出力+減結合及びスイッチオン補償(608)出力 式3
別の実施形態によれば、発電ブレーキ(DEB)が設けられ、これは風力タービンが発電機を停止させるのに電気ブレーキを加えることを可能にする。したがって、早期損傷を引き起こす可能性がある風力タービン構成要素の機械的力を回避することができる。
Pb_MAX=(VDC_bus)2/Rbrake 式4
式中、VDC_busは、DCバス電圧(Av_Ubus)の実際値である。
SP_Pb=Pb_MAX.fMOD 式5
fMOD=SP_Pb.(Rbrake/(Av_Ubus)2) 式6
別の実施形態に従って接続シーケンスが提供される。この実施形態は、電力電子変換器が系統に結合されていない、励磁機(212)に結合された二次励磁誘導発電機(DFIG)(205)と、系統への二次励磁誘導発電機の接続を可能にする接続シーケンスとを含み、この接続シーケンスは、無効エネルギーの消費も、接触器(215)を通る接続電流ピークもないため、接触器(215)の寿命を延ばす。図7は、接続シーケンスを示す。ここで説明する技法は、接触器の代わりに主回路遮断器又は任意の他のスイッチが系統への発電機の結合に用いられる場合にも適用できることが、当業者には明らかであろう。
本発明の別の実施形態に従って切断シーケンスが提供される。この実施形態は、電力電子変換器が系統に結合されていない、励磁機(212)に結合された二次励磁誘導発電機(DFIG)(205)と、システムの種々の要素における過電流又は過電圧に関係する摂動を伴わない、系統からの二次励磁誘導発電機(205)の切断を可能にする切断シーケンスとを含む。ほぼ0の電流で接触器(215)を開放するため、この接触器の寿命が延び、保守作業が減る。他の切断シーケンスと比較して、同じ用途で接触器の定格をより小さくすることもできる。
本発明のこの実施形態では、可変速風力タービンは、励磁機ベースピッチコントローラ(EBPC)を備える。図8は、励磁機への要求電力の制限に基づくこのようなピッチ制御システムの例示的な一実施形態を示す。
誤差_β=Sp_β−Av_β 式7
である。
誤差_n=Sp_n−Av_n 式8
である。
誤差_I=Sp_I−Av_I 式9
である。
本発明の別の実施形態では、可変速風力タービンは、励磁機への需要電力の制限に基づくピッチ制御システムを備える。
