　　今夏汛(xun)期，隨著長江來(lai)水流量增(zeng)大，總(zong)裝機(ji)容量1820萬(wan)千瓦(wa)的(de)三(san)峽水電(dian)站有望迎來(lai)2008年11月26臺機(ji)組(zu)全面投產后的(de)首次滿發。

　　三峽(xia)(xia)水電(dian)(dian)(dian)(dian)站(zhan)總裝機(ji)容量(liang)大，電(dian)(dian)(dian)(dian)力輸送(song)通道集中(zhong)，加之三峽(xia)(xia)來水的(de)(de)不確定(ding)(ding)性及負(fu)荷水平受宏觀經濟形勢影響，導(dao)致三峽(xia)(xia)近區(qu)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)潮流復雜多變，系統(tong)運(yun)行方式安(an)排難度大。為(wei)保證(zheng)三峽(xia)(xia)清潔水電(dian)(dian)(dian)(dian)全(quan)額送(song)出，確保電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)安(an)全(quan)穩(wen)定(ding)(ding)運(yun)行，國(guo)家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)公(gong)司及時研究，制訂了(le)(le)周密的(de)(de)應(ying)對措施。一是合(he)理(li)安(an)排迎峰(feng)度夏(xia)(xia)運(yun)行方式。在開展大量(liang)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)穩(wen)定(ding)(ding)專(zhuan)(zhuan)題分(fen)析(xi)計算和(he)驗證(zheng)的(de)(de)基礎上，統(tong)籌考(kao)慮特(te)高壓聯絡線(xian)、華(hua)北－華(hua)中(zhong)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)內(nei)部重要通道輸電(dian)(dian)(dian)(dian)能(neng)力，優化(hua)三峽(xia)(xia)近區(qu)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)潮流分(fen)布，制定(ding)(ding)了(le)(le)三峽(xia)(xia)26臺機(ji)組滿發(fa)的(de)(de)優化(hua)運(yun)行方案(an)(an)。二是統(tong)籌制定(ding)(ding)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)設(she)備檢修、新(xin)設(she)備啟動(dong)和(he)技(ji)改(gai)(gai)工作計劃。為(wei)保證(zheng)三峽(xia)(xia)電(dian)(dian)(dian)(dian)站(zhan)26臺機(ji)組首次(ci)滿發(fa)，充分(fen)發(fa)揮三峽(xia)(xia)近區(qu)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)交(jiao)直流通道輸送(song)能(neng)力，國(guo)家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)公(gong)司對系統(tong)設(she)備檢修、新(xin)設(she)備啟動(dong)和(he)技(ji)改(gai)(gai)工作進行了(le)(le)統(tong)籌優化(hua)，在度夏(xia)(xia)前完成了(le)(le)重要設(she)備檢修、新(xin)設(she)備啟動(dong)和(he)技(ji)改(gai)(gai)工程，確保了(le)(le)滿發(fa)期間三峽(xia)(xia)近區(qu)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)全(quan)接線(xian)、全(quan)保護運(yun)行。三是針對可能(neng)存在的(de)(de)安(an)全(quan)隱(yin)患，精心準備相應(ying)預案(an)(an)，先后組織了(le)(le)專(zhuan)(zhuan)項反(fan)事(shi)(shi)故演習(xi)、華(hua)中(zhong)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)聯合(he)反(fan)事(shi)(shi)故演習(xi)和(he)國(guo)家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)迎峰(feng)度夏(xia)(xia)聯合(he)反(fan)事(shi)(shi)故演習(xi)，從三個(ge)不同的(de)(de)層面全(quan)面檢驗事(shi)(shi)故緊急處理(li)預案(an)(an)和(he)各單位(wei)的(de)(de)協(xie)作配合(he)能(neng)力。

　　通過采取上述措施(shi)，保證了(le)三(san)峽電(dian)(dian)站滿發期(qi)間特(te)高壓(ya)互聯電(dian)(dian)網(wang)運(yun)行的(de)可靠性，為三(san)峽清潔水(shui)電(dian)(dian)向(xiang)華東(dong)、華中(zhong)和南方電(dian)(dian)網(wang)，以及通過特(te)高壓(ya)向(xiang)華北(bei)電(dian)(dian)網(wang)的(de)順利(li)送出創造了(le)條件，有效促進(jin)了(le)三(san)峽水(shui)電(dian)(dian)資源的(de)充分利(li)用。

　　目前，國家(jia)電網公(gong)司已為三峽電站26臺機(ji)組首次滿發做好(hao)充分(fen)準備。
