西電東送啟動工程
----華電(dian)集團烏江洪家(jia)渡水電(dian)站(zhan)首(shou)臺機(ji)組投產(chan)發電(dian)
經過三(san)年零八(ba)個月(yue)的努力，西電(dian)東送啟動工程中國(guo)華電(dian)集團公司烏江(jiang)洪(hong)家渡水電(dian)站首(shou)臺(tai)發電(dian)機組(zu)于7月(yue)17日完成72小時試運(yun)行，18日正式投產(chan)發電(dian)。洪(hong)家渡水電(dian)站首(shou)臺(tai)機組(zu)的投運(yun)，標(biao)志“西電(dian)東送”工程建設取(qu)得新的重(zhong)大進展。
洪家(jia)渡水電(dian)(dian)(dian)(dian)(dian)站(zhan)是“西電(dian)(dian)(dian)(dian)(dian)東(dong)送(song)”的(de)啟動工(gong)程，是烏江(jiang)梯級(ji)開(kai)發中(zhong)具有多年調節庫(ku)容(rong)的(de)龍頭電(dian)(dian)(dian)(dian)(dian)站(zhan)。其(qi)大壩壩高179.5米，填(tian)筑方(fang)(fang)量(liang)900萬(wan)立方(fang)(fang)米，是國內目(mu)前在建的(de)面板堆石壩之一；電(dian)(dian)(dian)(dian)(dian)站(zhan)廠(chang)房(fang)首(shou)次采用鋼(gang)結構，是水電(dian)(dian)(dian)(dian)(dian)站(zhan)廠(chang)房(fang)結構的(de)一次革(ge)新。電(dian)(dian)(dian)(dian)(dian)站(zhan)裝機(ji)容(rong)量(liang)60萬(wan)千(qian)瓦，水庫(ku)正(zheng)常(chang)蓄水位1140米，總(zong)庫(ku)容(rong)49.47億(yi)立方(fang)(fang)米，多年平均發電(dian)(dian)(dian)(dian)(dian)量(liang)15.94億(yi)千(qian)瓦時。電(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)建成，不僅可為“西電(dian)(dian)(dian)(dian)(dian)東(dong)送(song)”提供優(you)質(zhi)可靠的(de)電(dian)(dian)(dian)(dian)(dian)能，而且可極大地增強(qiang)烏江(jiang)下游各(ge)梯級(ji)電(dian)(dian)(dian)(dian)(dian)站(zhan)的(de)發電(dian)(dian)(dian)(dian)(dian)出(chu)力，經濟(ji)效(xiao)益和社會(hui)效(xiao)應十分顯著。
在工(gong)(gong)程(cheng)建設中，烏江(jiang)公司通過(guo)(guo)科技創新，引(yin)進(jin)新技術(shu)、新工(gong)(gong)藝、新材(cai)料，共(gong)優化(hua)重(zhong)大方案(an)20多(duo)項(xiang)，重(zhong)大技術(shu)推廣、創新10多(duo)項(xiang)，通過(guo)(guo)對(dui)泄洪系統、地面廠房、大壩、導流洞及場內施工(gong)(gong)布置(zhi)的優化(hua)，克服了不良(liang)地質(zhi)和(he)施工(gong)(gong)場地狹窄對(dui)工(gong)(gong)程(cheng)的不利(li)影(ying)響，安全、優質(zhi)、高效推進(jin)工(gong)(gong)程(cheng)進(jin)度，使(shi)首臺機(ji)組(zu)投產工(gong)(gong)期(qi)縮(suo)短兩年，總投資由(you)原來的78.4億(yi)(yi)元(yuan)降到了49.27億(yi)(yi)元(yuan)，一系列優化(hua)方案(an)使(shi)電站的市場競爭力得到顯著提高。
