今夏汛(xun)期，隨著(zhu)長江來水流(liu)量(liang)增大(da)，總裝機(ji)容量(liang)1820萬千瓦的(de)三峽水電站有(you)望迎(ying)來2008年11月26臺機(ji)組全面投產(chan)后的(de)首次滿發。
三(san)(san)峽(xia)水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)(dian)站總裝(zhuang)機(ji)容量大，電(dian)(dian)(dian)(dian)(dian)力(li)輸(shu)(shu)送通道集中(zhong)，加之三(san)(san)峽(xia)來水(shui)(shui)(shui)的(de)不確(que)定(ding)性及負(fu)荷水(shui)(shui)(shui)平受宏觀經(jing)濟形勢(shi)影響，導致三(san)(san)峽(xia)近(jin)區電(dian)(dian)(dian)(dian)(dian)網(wang)潮流復(fu)雜多變(bian)，系(xi)統(tong)(tong)運行方式安(an)排難度大。為保(bao)證三(san)(san)峽(xia)清潔水(shui)(shui)(shui)電(dian)(dian)(dian)(dian)(dian)全(quan)額送出，確(que)保(bao)電(dian)(dian)(dian)(dian)(dian)網(wang)安(an)全(quan)穩定(ding)運行，國家電(dian)(dian)(dian)(dian)(dian)網(wang)公(gong)司及時(shi)研究，制(zhi)訂了(le)周密的(de)應對(dui)措施。一是合(he)理安(an)排迎峰度夏運行方式。在(zai)(zai)開展大量電(dian)(dian)(dian)(dian)(dian)網(wang)穩定(ding)專題(ti)分(fen)析計算(suan)和(he)驗證的(de)基(ji)礎上，統(tong)(tong)籌考慮特高壓聯絡線(xian)、華北－華中(zhong)電(dian)(dian)(dian)(dian)(dian)網(wang)內部重(zhong)要通道輸(shu)(shu)電(dian)(dian)(dian)(dian)(dian)能力(li)，優化三(san)(san)峽(xia)近(jin)區電(dian)(dian)(dian)(dian)(dian)網(wang)潮流分(fen)布，制(zhi)定(ding)了(le)三(san)(san)峽(xia)26臺機(ji)組滿發(fa)(fa)的(de)優化運行方案。二是統(tong)(tong)籌制(zhi)定(ding)電(dian)(dian)(dian)(dian)(dian)網(wang)設(she)(she)(she)備(bei)檢(jian)(jian)修、新設(she)(she)(she)備(bei)啟動和(he)技改工作(zuo)計劃。為保(bao)證三(san)(san)峽(xia)電(dian)(dian)(dian)(dian)(dian)站26臺機(ji)組首次(ci)滿發(fa)(fa)，充分(fen)發(fa)(fa)揮三(san)(san)峽(xia)近(jin)區電(dian)(dian)(dian)(dian)(dian)網(wang)交直流通道輸(shu)(shu)送能力(li)，國家電(dian)(dian)(dian)(dian)(dian)網(wang)公(gong)司對(dui)系(xi)統(tong)(tong)設(she)(she)(she)備(bei)檢(jian)(jian)修、新設(she)(she)(she)備(bei)啟動和(he)技改工作(zuo)進行了(le)統(tong)(tong)籌優化，在(zai)(zai)度夏前(qian)完成了(le)重(zhong)要設(she)(she)(she)備(bei)檢(jian)(jian)修、新設(she)(she)(she)備(bei)啟動和(he)技改工程，確(que)保(bao)了(le)滿發(fa)(fa)期間三(san)(san)峽(xia)近(jin)區電(dian)(dian)(dian)(dian)(dian)網(wang)全(quan)接(jie)線(xian)、全(quan)保(bao)護(hu)運行。三(san)(san)是針對(dui)可(ke)能存在(zai)(zai)的(de)安(an)全(quan)隱患，精心準備(bei)相應預案，先后組織(zhi)了(le)專項(xiang)反事(shi)故(gu)演(yan)習、華中(zhong)電(dian)(dian)(dian)(dian)(dian)網(wang)聯合(he)反事(shi)故(gu)演(yan)習和(he)國家電(dian)(dian)(dian)(dian)(dian)網(wang)迎峰度夏聯合(he)反事(shi)故(gu)演(yan)習，從三(san)(san)個不同的(de)層面(mian)全(quan)面(mian)檢(jian)(jian)驗事(shi)故(gu)緊(jin)急(ji)處理預案和(he)各單位(wei)的(de)協作(zuo)配(pei)合(he)能力(li)。
通(tong)過采取上(shang)述措(cuo)施，保(bao)證(zheng)了三(san)峽(xia)電(dian)(dian)站滿發期間特高壓互聯電(dian)(dian)網運行(xing)的(de)可靠性，為三(san)峽(xia)清潔水電(dian)(dian)向華(hua)東、華(hua)中和南方(fang)電(dian)(dian)網，以及通(tong)過特高壓向華(hua)北電(dian)(dian)網的(de)順利送出(chu)創造了條件，有效促(cu)進了三(san)峽(xia)水電(dian)(dian)資(zi)源的(de)充分(fen)利用(yong)。
目前，國家電(dian)網公司(si)已為(wei)三(san)峽電(dian)站26臺機(ji)組首(shou)次(ci)滿發做好充分準備。
