12月20日(ri)17時10分，由中國(guo)葛洲壩集團公司安裝的(de)三峽水電(dian)站(zhan)17號(hao)機組正(zheng)式開始72小時試(shi)運行，這表明(ming)，三峽水電(dian)站(zhan)第4臺國(guo)產化(hua)機組投產發電(dian)指日(ri)可待(dai)。
17號機組(zu)于12月15日(ri)開始試(shi)運行(xing)(xing)。5天來，中國葛洲壩集(ji)團(tuan)公(gong)司的(de)技術人員對機組(zu)進行(xing)(xing)了發電機升(sheng)流試(shi)驗(yan)(yan)和升(sheng)壓試(shi)驗(yan)(yan)、過速試(shi)驗(yan)(yan)、升(sheng)溫試(shi)驗(yan)(yan)、計算機監控系統試(shi)驗(yan)(yan)、帶(dai)負(fu)(fu)荷(he)和甩負(fu)(fu)荷(he)試(shi)等15項(xiang)近120次(ci)專業試(shi)驗(yan)(yan)，檢測和監控數據表明，前期試(shi)運行(xing)(xing)效果(guo)良(liang)好，機組(zu)安裝質量達到了三峽優良(liang)標準。
經過(guo)嚴格精細地消(xiao)除機(ji)(ji)組(zu)的部分制造缺陷，業主正式(shi)同意(yi)開始72小(xiao)時試(shi)運行。這一期間，機(ji)(ji)組(zu)將連續滿負(fu)荷(he)運行，全面考(kao)核制造、安裝和調試(shi)質量(liang)，以(yi)確認機(ji)(ji)組(zu)可(ke)否并網(wang)安全運行。連續72小(xiao)時試(shi)運行成功后，機(ji)(ji)組(zu)將正式(shi)交付三峽電廠投入(ru)商業運行。
中(zhong)國葛(ge)洲(zhou)壩集團公司于今年2月7日(ri)開始17號(hao)(hao)機組的安(an)(an)(an)裝，11月1日(ri)，機組轉子吊裝順利(li)就位，12月14日(ri)完(wan)成安(an)(an)(an)裝及無水(shui)調試(shi)工(gong)(gong)作。機組安(an)(an)(an)裝過程(cheng)中(zhong)，中(zhong)國葛(ge)洲(zhou)壩集團公司全(quan)面實踐“安(an)(an)(an)裝進(jin)度(du)服從安(an)(an)(an)裝質量(liang)、以安(an)(an)(an)裝質量(liang)彌補安(an)(an)(an)裝缺(que)陷“的施工(gong)(gong)方針，嚴格(ge)執行“精(jing)(jing)益求(qiu)精(jing)(jing)、鍛造精(jing)(jing)品(pin)”的施工(gong)(gong)標(biao)準，嚴格(ge)按照既定的規程(cheng)組織安(an)(an)(an)裝，同時實施了針對性很(hen)強(qiang)的改進(jin)措(cuo)施。經過近(jin)乎苛刻的流(liu)程(cheng)化(hua)安(an)(an)(an)裝和(he)精(jing)(jing)益求(qiu)精(jing)(jing)地消除缺(que)陷，17號(hao)(hao)機組的安(an)(an)(an)裝排(pai)除了多(duo)輪(lun)技(ji)術風險，順利(li)進(jin)入72小(xiao)時試(shi)運行。
三(san)峽(xia)(xia)水(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)是全(quan)球最大的水(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan),設計安(an)裝(zhuang)32臺(tai)70萬(wan)千瓦(wa)水(shui)(shui)輪(lun)發電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)組(zu)(zu)(zu)。左(zuo)岸電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)14臺(tai)機(ji)(ji)組(zu)(zu)(zu)，均已(yi)投(tou)產(chan)發電(dian)(dian)(dian)(dian)(dian)(dian)；地下電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)6臺(tai)機(ji)(ji)組(zu)(zu)(zu)，已(yi)完成(cheng)招標，目(mu)前處于(yu)土建(jian)施工階段；右岸電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)12臺(tai)機(ji)(ji)組(zu)(zu)(zu)中(zhong)，有8臺(tai)是我國具有自主知識(shi)產(chan)權的國產(chan)化(hua)機(ji)(ji)組(zu)(zu)(zu)，全(quan)部(bu)由(you)中(zhong)國葛洲壩集團公(gong)司(si)安(an)裝(zhuang)。自今年7月(yue)10日(ri)(ri)第1臺(tai)國產(chan)化(hua)機(ji)(ji)組(zu)(zu)(zu)26號(hao)機(ji)(ji)組(zu)(zu)(zu)正式(shi)并網發電(dian)(dian)(dian)(dian)(dian)(dian)以(yi)來，三(san)峽(xia)(xia)水(shui)(shui)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)已(yi)有3臺(tai)國產(chan)化(hua)70萬(wan)千瓦(wa)水(shui)(shui)輪(lun)發電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)組(zu)(zu)(zu)投(tou)產(chan)發電(dian)(dian)(dian)(dian)(dian)(dian)，其中(zhong)的18號(hao)機(ji)(ji)組(zu)(zu)(zu)和25號(hao)機(ji)(ji)組(zu)(zu)(zu)已(yi)分別于(yu)今年10月(yue)22 日(ri)(ri)和11月(yue)6日(ri)(ri)投(tou)產(chan)發電(dian)(dian)(dian)(dian)(dian)(dian)。
三峽右岸電站17號機組即將投產發電，意味著中國葛洲壩集團公司2007年將在三峽工程中實現年裝機總容量280萬千瓦，比整個葛洲壩水電站的裝機容量271.5萬千瓦還多8.5萬千瓦。
