雙驅變槳系統以及風力發電機組的制作方法

本公開總體說來涉及風電領域(yu),更具體地講,涉及一種雙驅變槳系統以及風力發電機(ji)組(zu)。


背景技術:

1、隨(sui)著風(feng)(feng)力(li)發(fa)電機組(zu)(可簡稱為風(feng)(feng)機、風(feng)(feng)電機組(zu)或(huo)機組(zu))逐(zhu)漸向大(da)(da)型化、大(da)(da)容量的(de)方向發(fa)展,風(feng)(feng)力(li)發(fa)電機組(zu)的(de)功率(lv)等級不(bu)斷提(ti)高,造成葉根載(zai)荷也(ye)隨(sui)之上升,這對變(bian)槳(jiang)系(xi)統的(de)驅動能(neng)(neng)力(li)和安全性能(neng)(neng)提(ti)出(chu)了更高的(de)要(yao)求(qiu)。

2、采用三通道(dao)安(an)全(quan)檢測的雙(shuang)驅動器、雙(shuang)電(dian)機架構(gou)的雙(shuang)驅變(bian)槳安(an)全(quan)系(xi)統在保證變(bian)槳系(xi)統輸出能力(li)和控制風力(li)發電(dian)機組(zu)成本的同時,極(ji)大(da)提高了(le)雙(shuang)驅變(bian)槳系(xi)統的安(an)全(quan)性(xing),對電(dian)控驅動變(bian)槳系(xi)統的研究具有重要意義。

3、為應對不(bu)斷提高的(de)功率和安(an)全(quan)需求,目前主(zhu)要采用的(de)雙(shuang)(shuang)(shuang)電(dian)(dian)機(ji)(ji)驅(qu)動(dong)(dong)葉(xie)片以(yi)實現大載(zai)荷(he)葉(xie)片調槳(jiang)(jiang)(jiang)(jiang)的(de)電(dian)(dian)控(kong)(kong)雙(shuang)(shuang)(shuang)驅(qu)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)方案可參照(zhao)圖1,圖1示(shi)出了現有的(de)雙(shuang)(shuang)(shuang)驅(qu)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)系統(tong)(tong)(tong)(tong)的(de)框圖,雙(shuang)(shuang)(shuang)電(dian)(dian)機(ji)(ji)驅(qu)動(dong)(dong)的(de)雙(shuang)(shuang)(shuang)驅(qu)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)系統(tong)(tong)(tong)(tong)是在(zai)傳統(tong)(tong)(tong)(tong)單(dan)電(dian)(dian)機(ji)(ji)驅(qu)動(dong)(dong)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)系統(tong)(tong)(tong)(tong)基礎上發展(zhan)而(er)來的(de)一種新型變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)系統(tong)(tong)(tong)(tong)。每支葉(xie)片由兩(liang)個(ge)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)電(dian)(dian)機(ji)(ji)(第(di)(di)(di)一變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)電(dian)(dian)機(ji)(ji)和第(di)(di)(di)二(er)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)電(dian)(dian)機(ji)(ji))分(fen)別通(tong)過兩(liang)個(ge)減速器(qi)(qi)(即,第(di)(di)(di)一減速器(qi)(qi)和第(di)(di)(di)二(er)減速器(qi)(qi))連接(jie)到變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)軸承,這兩(liang)個(ge)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)電(dian)(dian)機(ji)(ji)分(fen)別由第(di)(di)(di)一變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)驅(qu)動(dong)(dong)器(qi)(qi)和第(di)(di)(di)二(er)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)驅(qu)動(dong)(dong)器(qi)(qi)控(kong)(kong)制(zhi),共同(tong)驅(qu)動(dong)(dong)葉(xie)片轉動(dong)(dong)以(yi)應對不(bu)斷增加的(de)葉(xie)根載(zai)荷(he)。整個(ge)系統(tong)(tong)(tong)(tong)包含六(liu)(liu)個(ge)驅(qu)動(dong)(dong)器(qi)(qi)、六(liu)(liu)個(ge)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)電(dian)(dian)機(ji)(ji)、六(liu)(liu)個(ge)減速器(qi)(qi),以(yi)及三組獨立(li)的(de)備用電(dian)(dian)源(每組包含第(di)(di)(di)一變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)驅(qu)動(dong)(dong)器(qi)(qi)和第(di)(di)(di)二(er)變(bian)(bian)槳(jiang)(jiang)(jiang)(jiang)驅(qu)動(dong)(dong)器(qi)(qi))、限位開(kai)關和接(jie)近開(kai)關等其(qi)他附(fu)件。

4、以上雙(shuang)(shuang)(shuang)驅變(bian)(bian)槳系統(tong)可(ke)以減(jian)小(xiao)對變(bian)(bian)槳軸承的(de)(de)沖(chong)擊,提高變(bian)(bian)槳系統(tong)扭矩輸出(chu)能(neng)力。然而,在雙(shuang)(shuang)(shuang)驅變(bian)(bian)槳系統(tong)的(de)(de)零(ling)部件(jian)增加(jia)的(de)(de)同時,系統(tong)復(fu)雜(za)性也隨之增加(jia),導致(zhi)安全(quan)性能(neng)降低(di)。此外(wai),雙(shuang)(shuang)(shuang)電機、雙(shuang)(shuang)(shuang)減(jian)速器占用了腹(fu)板(ban)的(de)(de)兩(liang)個連接孔(kong),其中一個出(chu)現問題時,就可(ke)能(neng)造(zao)成整個腹(fu)板(ban)的(de)(de)更換(huan),冗(rong)余性不足(zu)。

5、此外,面(mian)對當前日益嚴峻的(de)(de)(de)價格競爭,保(bao)證(zheng)變槳(jiang)系統輸出能(neng)力(li)的(de)(de)(de)同時(shi),控制成(cheng)本也是(shi)風力(li)發電(dian)(dian)機組設(she)計(ji)研發時(shi)一個(ge)不可忽視的(de)(de)(de)因(yin)素,而雙(shuang)驅、雙(shuang)電(dian)(dian)機的(de)(de)(de)設(she)計(ji)以(yi)及后期維(wei)護必然會造成(cheng)機組設(she)計(ji)成(cheng)本的(de)(de)(de)增加。
