　　今夏汛期，隨著長江來(lai)(lai)水流量增大(da)，總裝機(ji)容(rong)量1820萬千瓦的三峽水電(dian)站有(you)望(wang)迎來(lai)(lai)2008年11月(yue)26臺機(ji)組全面投產后的首(shou)次滿發(fa)。

　　三(san)峽水(shui)電(dian)(dian)(dian)(dian)站總(zong)裝機容量大，電(dian)(dian)(dian)(dian)力輸送通道集中(zhong)(zhong)，加之三(san)峽來水(shui)的(de)不確(que)定(ding)性及負荷水(shui)平受宏觀經濟(ji)形勢影響，導(dao)致三(san)峽近(jin)區電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)潮流(liu)(liu)復雜(za)多變，系統(tong)運行(xing)方(fang)式安排(pai)難度大。為保(bao)證(zheng)三(san)峽清潔(jie)水(shui)電(dian)(dian)(dian)(dian)全(quan)(quan)額送出，確(que)保(bao)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)安全(quan)(quan)穩定(ding)運行(xing)，國家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)公(gong)司及時研究，制(zhi)訂(ding)了(le)(le)(le)周密的(de)應對措(cuo)施。一是(shi)合(he)理(li)安排(pai)迎峰度夏(xia)運行(xing)方(fang)式。在開(kai)展大量電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)穩定(ding)專(zhuan)(zhuan)題分析(xi)計算和驗(yan)證(zheng)的(de)基礎上(shang)，統(tong)籌考慮(lv)特(te)高壓聯(lian)絡線、華(hua)北(bei)－華(hua)中(zhong)(zhong)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)內部(bu)重(zhong)要(yao)通道輸電(dian)(dian)(dian)(dian)能(neng)(neng)力，優(you)化三(san)峽近(jin)區電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)潮流(liu)(liu)分布，制(zhi)定(ding)了(le)(le)(le)三(san)峽26臺(tai)機組(zu)(zu)滿(man)發的(de)優(you)化運行(xing)方(fang)案。二是(shi)統(tong)籌制(zhi)定(ding)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)設(she)(she)備(bei)(bei)檢(jian)(jian)(jian)修、新(xin)設(she)(she)備(bei)(bei)啟(qi)動(dong)和技(ji)改工作(zuo)計劃(hua)。為保(bao)證(zheng)三(san)峽電(dian)(dian)(dian)(dian)站26臺(tai)機組(zu)(zu)首(shou)次(ci)滿(man)發，充分發揮三(san)峽近(jin)區電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)交直流(liu)(liu)通道輸送能(neng)(neng)力，國家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)公(gong)司對系統(tong)設(she)(she)備(bei)(bei)檢(jian)(jian)(jian)修、新(xin)設(she)(she)備(bei)(bei)啟(qi)動(dong)和技(ji)改工作(zuo)進行(xing)了(le)(le)(le)統(tong)籌優(you)化，在度夏(xia)前完成(cheng)了(le)(le)(le)重(zhong)要(yao)設(she)(she)備(bei)(bei)檢(jian)(jian)(jian)修、新(xin)設(she)(she)備(bei)(bei)啟(qi)動(dong)和技(ji)改工程(cheng)，確(que)保(bao)了(le)(le)(le)滿(man)發期(qi)間(jian)三(san)峽近(jin)區電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)全(quan)(quan)接線、全(quan)(quan)保(bao)護運行(xing)。三(san)是(shi)針對可能(neng)(neng)存在的(de)安全(quan)(quan)隱患，精心準備(bei)(bei)相應預(yu)案，先(xian)后組(zu)(zu)織了(le)(le)(le)專(zhuan)(zhuan)項反事故(gu)演習(xi)、華(hua)中(zhong)(zhong)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)聯(lian)合(he)反事故(gu)演習(xi)和國家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)迎峰度夏(xia)聯(lian)合(he)反事故(gu)演習(xi)，從(cong)三(san)個不同的(de)層面全(quan)(quan)面檢(jian)(jian)(jian)驗(yan)事故(gu)緊急處理(li)預(yu)案和各(ge)單位的(de)協作(zuo)配合(he)能(neng)(neng)力。

　　通過采取上述措施，保證了(le)(le)(le)三(san)峽(xia)電(dian)(dian)站(zhan)滿發(fa)期間特高壓(ya)互聯電(dian)(dian)網(wang)運(yun)行的(de)可靠性，為三(san)峽(xia)清潔水電(dian)(dian)向華東、華中和南方電(dian)(dian)網(wang)，以及通過特高壓(ya)向華北電(dian)(dian)網(wang)的(de)順(shun)利送(song)出創造了(le)(le)(le)條件(jian)，有效促進(jin)了(le)(le)(le)三(san)峽(xia)水電(dian)(dian)資源的(de)充分(fen)利用(yong)。

　　目前，國家(jia)電網公司已為(wei)三(san)峽電站26臺(tai)機組首次滿發(fa)做好充分準備。
