　　今夏汛期，隨著長江來(lai)(lai)水(shui)流量(liang)增大，總裝(zhuang)機(ji)容量(liang)1820萬千瓦(wa)的三峽水(shui)電站有望迎來(lai)(lai)2008年11月26臺機(ji)組(zu)全面投(tou)產后的首次滿(man)發(fa)。

　　三峽水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)站總(zong)裝(zhuang)機容量大，電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)(li)輸(shu)送(song)(song)(song)通道集中，加之(zhi)三峽來水(shui)的不(bu)確(que)(que)定(ding)性及(ji)負荷水(shui)平(ping)受宏觀經(jing)濟(ji)形勢(shi)影響，導致三峽近區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)網潮(chao)流(liu)(liu)復(fu)雜多變，系(xi)統(tong)運(yun)行(xing)(xing)(xing)方式安排難度大。為保(bao)(bao)(bao)證(zheng)三峽清(qing)潔水(shui)電(dian)(dian)(dian)(dian)(dian)(dian)全(quan)(quan)額(e)送(song)(song)(song)出，確(que)(que)保(bao)(bao)(bao)電(dian)(dian)(dian)(dian)(dian)(dian)網安全(quan)(quan)穩(wen)定(ding)運(yun)行(xing)(xing)(xing)，國(guo)家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)網公司及(ji)時研究，制(zhi)訂了(le)(le)周密的應(ying)對(dui)措施。一(yi)是(shi)(shi)合理(li)安排迎峰度夏(xia)(xia)(xia)運(yun)行(xing)(xing)(xing)方式。在開展大量電(dian)(dian)(dian)(dian)(dian)(dian)網穩(wen)定(ding)專(zhuan)題分析(xi)計(ji)算和(he)(he)(he)驗(yan)證(zheng)的基(ji)礎(chu)上，統(tong)籌考(kao)慮特高壓(ya)聯絡線、華北－華中電(dian)(dian)(dian)(dian)(dian)(dian)網內部(bu)重要通道輸(shu)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)力(li)(li)(li)，優化(hua)(hua)三峽近區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)網潮(chao)流(liu)(liu)分布，制(zhi)定(ding)了(le)(le)三峽26臺(tai)機組滿發(fa)的優化(hua)(hua)運(yun)行(xing)(xing)(xing)方案。二是(shi)(shi)統(tong)籌制(zhi)定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)網設(she)(she)備(bei)檢修、新(xin)設(she)(she)備(bei)啟(qi)動(dong)(dong)和(he)(he)(he)技(ji)改(gai)工作計(ji)劃。為保(bao)(bao)(bao)證(zheng)三峽電(dian)(dian)(dian)(dian)(dian)(dian)站26臺(tai)機組首次滿發(fa)，充分發(fa)揮(hui)三峽近區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)網交(jiao)直流(liu)(liu)通道輸(shu)送(song)(song)(song)能(neng)力(li)(li)(li)，國(guo)家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)網公司對(dui)系(xi)統(tong)設(she)(she)備(bei)檢修、新(xin)設(she)(she)備(bei)啟(qi)動(dong)(dong)和(he)(he)(he)技(ji)改(gai)工作進行(xing)(xing)(xing)了(le)(le)統(tong)籌優化(hua)(hua)，在度夏(xia)(xia)(xia)前完成了(le)(le)重要設(she)(she)備(bei)檢修、新(xin)設(she)(she)備(bei)啟(qi)動(dong)(dong)和(he)(he)(he)技(ji)改(gai)工程，確(que)(que)保(bao)(bao)(bao)了(le)(le)滿發(fa)期間三峽近區(qu)電(dian)(dian)(dian)(dian)(dian)(dian)網全(quan)(quan)接線、全(quan)(quan)保(bao)(bao)(bao)護運(yun)行(xing)(xing)(xing)。三是(shi)(shi)針對(dui)可能(neng)存(cun)在的安全(quan)(quan)隱(yin)患，精(jing)心準備(bei)相應(ying)預案，先后(hou)組織了(le)(le)專(zhuan)項(xiang)反(fan)事故(gu)演(yan)習(xi)(xi)、華中電(dian)(dian)(dian)(dian)(dian)(dian)網聯合反(fan)事故(gu)演(yan)習(xi)(xi)和(he)(he)(he)國(guo)家(jia)電(dian)(dian)(dian)(dian)(dian)(dian)網迎峰度夏(xia)(xia)(xia)聯合反(fan)事故(gu)演(yan)習(xi)(xi)，從三個不(bu)同的層面全(quan)(quan)面檢驗(yan)事故(gu)緊急處理(li)預案和(he)(he)(he)各單(dan)位的協作配合能(neng)力(li)(li)(li)。

　　通(tong)過采取上述措施，保證了(le)(le)三(san)峽電(dian)(dian)站滿發(fa)期間特(te)高(gao)壓互聯電(dian)(dian)網運行的(de)可靠(kao)性，為三(san)峽清(qing)潔(jie)水電(dian)(dian)向華(hua)(hua)東、華(hua)(hua)中(zhong)和南方電(dian)(dian)網，以及通(tong)過特(te)高(gao)壓向華(hua)(hua)北(bei)電(dian)(dian)網的(de)順利送出創(chuang)造了(le)(le)條件，有效促進了(le)(le)三(san)峽水電(dian)(dian)資(zi)源的(de)充分利用(yong)。

　　目(mu)前，國(guo)家電網公司已為三(san)峽電站26臺(tai)機組首次(ci)滿發做好充分準備。
