西電東送啟動工程
----華電集團烏江洪家渡水電站首(shou)臺機(ji)組(zu)投產發電
經(jing)過三年零八個月的(de)(de)努力，西電(dian)(dian)東(dong)送啟(qi)動工程中國華電(dian)(dian)集團公司烏(wu)江(jiang)洪家渡水電(dian)(dian)站(zhan)首(shou)(shou)臺(tai)發(fa)電(dian)(dian)機組(zu)于7月17日(ri)完(wan)成(cheng)72小時試運行(xing)，18日(ri)正式投(tou)產發(fa)電(dian)(dian)。洪家渡水電(dian)(dian)站(zhan)首(shou)(shou)臺(tai)機組(zu)的(de)(de)投(tou)運，標志(zhi)“西電(dian)(dian)東(dong)送”工程建設取得(de)新(xin)的(de)(de)重大進(jin)展。
洪家(jia)渡水(shui)(shui)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)是“西電(dian)(dian)(dian)(dian)(dian)東送(song)”的(de)啟動工程，是烏江(jiang)(jiang)梯級開發中具有多年(nian)調節庫容(rong)的(de)龍頭電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)。其(qi)大(da)壩(ba)壩(ba)高179.5米，填筑方(fang)(fang)量900萬立方(fang)(fang)米，是國內目(mu)前在建(jian)的(de)面(mian)板堆石壩(ba)之一；電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)廠房(fang)首次采用鋼結構，是水(shui)(shui)電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)廠房(fang)結構的(de)一次革新(xin)。電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)裝機容(rong)量60萬千瓦，水(shui)(shui)庫正(zheng)常蓄水(shui)(shui)位1140米，總(zong)庫容(rong)49.47億立方(fang)(fang)米，多年(nian)平均(jun)發電(dian)(dian)(dian)(dian)(dian)量15.94億千瓦時(shi)。電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)的(de)建(jian)成，不僅(jin)可(ke)為“西電(dian)(dian)(dian)(dian)(dian)東送(song)”提(ti)供優質(zhi)可(ke)靠的(de)電(dian)(dian)(dian)(dian)(dian)能，而且可(ke)極大(da)地增強烏江(jiang)(jiang)下游各梯級電(dian)(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)的(de)發電(dian)(dian)(dian)(dian)(dian)出力，經濟效益和社會效應(ying)十分(fen)顯著。
在工程(cheng)建設中，烏江公司通過(guo)科(ke)技(ji)創(chuang)新(xin)，引進新(xin)技(ji)術、新(xin)工藝(yi)、新(xin)材料，共優(you)化(hua)重大(da)方案20多項(xiang)，重大(da)技(ji)術推(tui)廣、創(chuang)新(xin)10多項(xiang)，通過(guo)對泄(xie)洪系統、地(di)(di)面廠(chang)房、大(da)壩、導流洞及場內(nei)施(shi)工布置的優(you)化(hua)，克服了(le)不良地(di)(di)質和施(shi)工場地(di)(di)狹(xia)窄對工程(cheng)的不利(li)影響，安全、優(you)質、高效推(tui)進工程(cheng)進度，使首臺機組投(tou)產工期縮短(duan)兩年，總(zong)投(tou)資由原來(lai)的78.4億元降到(dao)了(le)49.27億元，一系列優(you)化(hua)方案使電站的市(shi)場競爭(zheng)力得到(dao)顯著(zhu)提高。
