西電東送啟動工程
----華電(dian)集團烏江洪家渡水電(dian)站首臺機組投(tou)產發(fa)電(dian)
經過(guo)三年(nian)零八個月的(de)(de)努力(li)，西電(dian)東送啟動工程中(zhong)國華電(dian)集(ji)團公司烏(wu)江洪家(jia)渡水電(dian)站首(shou)臺發電(dian)機組于7月17日完成72小時試運(yun)行，18日正式(shi)投產發電(dian)。洪家(jia)渡水電(dian)站首(shou)臺機組的(de)(de)投運(yun)，標志“西電(dian)東送”工程建設取得新的(de)(de)重大進展。
洪家渡(du)水電(dian)(dian)(dian)(dian)(dian)站(zhan)是(shi)“西電(dian)(dian)(dian)(dian)(dian)東送”的(de)(de)(de)(de)啟動工程，是(shi)烏江梯級(ji)開(kai)發(fa)中具有多年調節(jie)庫容(rong)的(de)(de)(de)(de)龍頭電(dian)(dian)(dian)(dian)(dian)站(zhan)。其大壩壩高(gao)179.5米(mi)，填(tian)筑(zhu)方量(liang)900萬立(li)方米(mi)，是(shi)國(guo)內(nei)目前在建(jian)的(de)(de)(de)(de)面板堆石壩之一；電(dian)(dian)(dian)(dian)(dian)站(zhan)廠房(fang)首次(ci)采(cai)用(yong)鋼結構，是(shi)水電(dian)(dian)(dian)(dian)(dian)站(zhan)廠房(fang)結構的(de)(de)(de)(de)一次(ci)革新。電(dian)(dian)(dian)(dian)(dian)站(zhan)裝機容(rong)量(liang)60萬千(qian)瓦(wa)，水庫正常蓄水位(wei)1140米(mi)，總庫容(rong)49.47億立(li)方米(mi)，多年平均發(fa)電(dian)(dian)(dian)(dian)(dian)量(liang)15.94億千(qian)瓦(wa)時。電(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)(de)(de)建(jian)成，不僅可為“西電(dian)(dian)(dian)(dian)(dian)東送”提供優質可靠的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)能，而且可極大地(di)增強烏江下游各梯級(ji)電(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)(de)(de)(de)發(fa)電(dian)(dian)(dian)(dian)(dian)出力，經濟效益(yi)和社會(hui)效應十分顯著。
在(zai)工(gong)程(cheng)(cheng)建設中(zhong)，烏江公司通(tong)過(guo)科技(ji)創(chuang)新(xin)，引進新(xin)技(ji)術、新(xin)工(gong)藝、新(xin)材料，共優化重大方案20多項，重大技(ji)術推廣、創(chuang)新(xin)10多項，通(tong)過(guo)對(dui)泄(xie)洪系統、地面(mian)廠房(fang)、大壩(ba)、導(dao)流洞(dong)及(ji)場(chang)內施工(gong)布(bu)置的優化，克服(fu)了不良地質(zhi)(zhi)和(he)施工(gong)場(chang)地狹窄對(dui)工(gong)程(cheng)(cheng)的不利影響，安全、優質(zhi)(zhi)、高(gao)效(xiao)推進工(gong)程(cheng)(cheng)進度，使首臺機組投產工(gong)期縮短兩年(nian)，總投資由原來的78.4億元降到了49.27億元，一(yi)系列優化方案使電站的市場(chang)競(jing)爭力得(de)到顯著提高(gao)。
