　　4月25日，由葛洲壩集團機電(dian)(dian)建(jian)設(she)公司三峽機電(dian)(dian)安(an)裝(zhuang)處承擔安(an)裝(zhuang)調(diao)試(shi)的三峽地(di)下電(dian)(dian)站首(shou)臺(tai)機組尾水系統成功充水，拉開了(le)首(shou)臺(tai)機組充水調(diao)試(shi)的序幕，標志著(zhu)三峽地(di)電(dian)(dian)首(shou)臺(tai)機組進入了(le)有水調(diao)試(shi)階段，投產發電(dian)(dian)指日可待。

　　充(chong)(chong)水(shui)(shui)(shui)是(shi)機(ji)(ji)組(zu)啟(qi)動試(shi)(shi)運(yun)行(xing)的重要一環，是(shi)機(ji)(ji)組(zu)能否順(shun)利(li)進入(ru)(ru)試(shi)(shi)運(yun)行(xing)的基礎，也(ye)是(shi)檢驗廠壩、流道(dao)和(he)機(ji)(ji)電(dian)設備(bei)安(an)裝質(zhi)量的起(qi)點。據了解，機(ji)(ji)組(zu)充(chong)(chong)水(shui)(shui)(shui)即對尾水(shui)(shui)(shui)洞、尾水(shui)(shui)(shui)管及壓力鋼(gang)管、蝸殼等流道(dao)進行(xing)充(chong)(chong)水(shui)(shui)(shui)，其中尾水(shui)(shui)(shui)充(chong)(chong)水(shui)(shui)(shui)是(shi)機(ji)(ji)組(zu)試(shi)(shi)運(yun)行(xing)的首道(dao)程序(xu)。32號(hao)機(ji)(ji)組(zu)自2010年(nian)4月1日定子機(ji)(ji)座進入(ru)(ru)施工現(xian)場開(kai)始安(an)裝以來(lai)，先后(hou)(hou)完成了轉(zhuan)子、定子組(zu)裝調(diao)試(shi)(shi)，機(ji)(ji)組(zu)總(zong)裝調(diao)試(shi)(shi)及相關試(shi)(shi)驗，并順(shun)利(li)完成機(ji)(ji)組(zu)各單(dan)(dan)元(yuan)無(wu)水(shui)(shui)(shui)調(diao)試(shi)(shi)工作，具(ju)備(bei)了充(chong)(chong)水(shui)(shui)(shui)調(diao)試(shi)(shi)條件。當天11時(shi)38分，隨(sui)著安(an)裝單(dan)(dan)位試(shi)(shi)運(yun)行(xing)指揮(hui)(hui)部(bu)指揮(hui)(hui)長周暉一聲令下，32#機(ji)(ji)組(zu)尾水(shui)(shui)(shui)閘門徐(xu)徐(xu)提起(qi)，湍急的江(jiang)水(shui)(shui)(shui)朝尾水(shui)(shui)(shui)洞奔(ben)涌而入(ru)(ru)，5個小時(shi)后(hou)(hou)，整個尾水(shui)(shui)(shui)系統順(shun)利(li)完成充(chong)(chong)水(shui)(shui)(shui)。

　　為(wei)了保(bao)證充(chong)水調試順利(li)完成，葛洲壩集(ji)團機電建(jian)設公司三峽機電安(an)裝處的(de)施工(gong)人員對充(chong)水準備工(gong)作做(zuo)了周密(mi)嚴謹(jin)的(de)部署。業主、監理(li)、設計、廠家(jia)、安(an)全檢(jian)測及各施工(gong)單位組成聯合檢(jian)查組，在充(chong)水前對流道和(he)相關設備等眾多項目進(jin)行(xing)聯合檢(jian)測，并制訂了完善的(de)應急預案。

　　首臺機組充(chong)水(shui)順利完成，4月26日進行壓(ya)力鋼管充(chong)水(shui)、靜水(shui)下調(diao)(diao)速(su)器試驗與技術(shu)供水(shui)有水(shui)調(diao)(diao)試等工作，計劃(hua)28日進行首次啟(qi)動及空載(zai)、帶負荷試驗。

　　三峽水電(dian)(dian)(dian)(dian)(dian)站是世界(jie)上規(gui)模(mo)最大(da)(da)的(de)(de)(de)水電(dian)(dian)(dian)(dian)(dian)站，也(ye)是中國(guo)有史以來(lai)建(jian)(jian)設最大(da)(da)型的(de)(de)(de)工(gong)程項目，水電(dian)(dian)(dian)(dian)(dian)站大(da)(da)壩高185米，蓄水高175米，水庫長(chang)600余公里，安裝(zhuang)32臺(tai)單機(ji)(ji)容量(liang)(liang)為70萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)的(de)(de)(de)水電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)組，是全世界(jie)最大(da)(da)的(de)(de)(de)（裝(zhuang)機(ji)(ji)容量(liang)(liang)）水力(li)發電(dian)(dian)(dian)(dian)(dian)站。電(dian)(dian)(dian)(dian)(dian)站初(chu)期規(gui)劃是26臺(tai)70萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)的(de)(de)(de)機(ji)(ji)組，也(ye)就是裝(zhuang)機(ji)(ji)容量(liang)(liang)為1820萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)，年(nian)發電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)847億度(du)。后又在右岸大(da)(da)壩“白石尖”山體內建(jian)(jian)設地下(xia)電(dian)(dian)(dian)(dian)(dian)站（即，三峽地下(xia)電(dian)(dian)(dian)(dian)(dian)站），建(jian)(jian)6臺(tai)70萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)的(de)(de)(de)水輪(lun)發電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)。再加(jia)上三峽電(dian)(dian)(dian)(dian)(dian)站自(zi)身的(de)(de)(de)兩臺(tai)5萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)站。總裝(zhuang)機(ji)(ji)容量(liang)(liang)達到(dao)了2250萬(wan)千(qian)(qian)(qian)瓦(wa)(wa)，年(nian)發電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)約1000億度(du)（5倍于(yu)(yu)葛洲壩，10倍于(yu)(yu)大(da)(da)亞灣核電(dian)(dian)(dian)(dian)(dian)，約占全國(guo)年(nian)發電(dian)(dian)(dian)(dian)(dian)總量(liang)(liang)的(de)(de)(de)3%，水力(li)發電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)20%）。

　　三峽(xia)地下電(dian)站共設計安(an)裝(zhuang)(zhuang)6臺(tai)70萬千(qian)瓦全國產化(hua)機(ji)(ji)(ji)組(zu)，分(fen)別(bie)由(you)哈爾濱電(dian)機(ji)(ji)(ji)廠(chang)、東方電(dian)機(ji)(ji)(ji)廠(chang)及天津ALSTOM三個廠(chang)家設計、制造，機(ji)(ji)(ji)組(zu)結構各不相同，安(an)裝(zhuang)(zhuang)、調(diao)(diao)試難度(du)極(ji)大(da)。葛洲壩集團機(ji)(ji)(ji)電(dian)建(jian)設公司承擔了全部六臺(tai)機(ji)(ji)(ji)組(zu)及全廠(chang)公用系統設備的安(an)裝(zhuang)(zhuang)與(yu)調(diao)(diao)試任務，在(zai)此安(an)裝(zhuang)(zhuang)與(yu)調(diao)(diao)試過(guo)程中，安(an)裝(zhuang)(zhuang)單位以三峽(xia)左、右(you)岸(an)已(yi)投產發電(dian)機(ji)(ji)(ji)組(zu)最優技術標(biao)準(zhun)作為(wei)機(ji)(ji)(ji)組(zu)安(an)裝(zhuang)(zhuang)調(diao)(diao)試控制標(biao)準(zhun)，態(tai)度(du)精心(xin)、過(guo)程精細(xi)地抓好質(zhi)量(liang)過(guo)程控制，最終使首批（32號、31號、30號）機(ji)(ji)(ji)組(zu)轉子、定子安(an)裝(zhuang)(zhuang)質(zhi)量(liang)均穩(wen)定保持在(zai)0.06mm—0.065mm之間，整體超越(yue)三峽(xia)左、右(you)岸(an)優良(liang)水平。

　　截至目前(qian)，三峽地下(xia)電站公用系統設備(bei)安裝與調試(shi)(shi)工(gong)(gong)程正按機(ji)組施(shi)工(gong)(gong)進(jin)(jin)度快速跟進(jin)(jin)，6臺70萬千瓦機(ji)組均按計劃控制(zhi)節點(dian)目標穩步推進(jin)(jin)：其中，32號機(ji)組將(jiang)于4月底啟動啟動進(jin)(jin)入有水調試(shi)(shi)階段；31號機(ji)組總裝調試(shi)(shi)接近尾聲；30號機(ji)組正進(jin)(jin)行(xing)轉子吊裝前(qian)的準備(bei)工(gong)(gong)作。

　　預計，三(san)峽地下電(dian)站首批機組將于2011年5月、6月、7月分別(bie)有一臺70萬千瓦機組投產發電(dian)。
