今夏(xia)汛期(qi)，總裝機(ji)1820萬千瓦的三(san)峽(xia)水電(dian)(dian)(dian)站將迎來(lai)26臺機(ji)組全面投產后的首次滿發。作為世(shi)界上裝機(ji)規模(mo)最大的水電(dian)(dian)(dian)站，其滿發狀態下的電(dian)(dian)(dian)力(li)輸送將對電(dian)(dian)(dian)網(wang)產生(sheng)極大影響。為確保三(san)峽(xia)電(dian)(dian)(dian)站滿發下的電(dian)(dian)(dian)力(li)輸送，應對今夏(xia)華中電(dian)(dian)(dian)網(wang)大負(fu)荷運(yun)行(xing)方式下的新情況(kuang)、新變化，5月13日(ri)，華中電(dian)(dian)(dian)網(wang)有限公司電(dian)(dian)(dian)力(li)調度中心舉行(xing)了(le)一場專項反事故演習，為確保汛期(qi)大電(dian)(dian)(dian)網(wang)安全運(yun)行(xing)做好了(le)調度準備。
據(ju)介紹，在(zai)三峽電(dian)(dian)(dian)(dian)站(zhan)(zhan)滿(man)發情況下(xia)，三峽電(dian)(dian)(dian)(dian)力(li)外送(song)重(zhong)要樞紐500千伏江(jiang)陵變電(dian)(dian)(dian)(dian)站(zhan)(zhan)短(duan)路電(dian)(dian)(dian)(dian)流超標問題將十分(fen)(fen)突出(chu)(chu)，而(er)從硬件配(pei)備上，江(jiang)陵變電(dian)(dian)(dian)(dian)站(zhan)(zhan)短(duan)路電(dian)(dian)(dian)(dian)流開(kai)關(guan)已經是最高(gao)配(pei)置，無(wu)法更換。為(wei)此，華中(zhong)公(gong)司從改(gai)變電(dian)(dian)(dian)(dian)網(wang)(wang)結構(gou)上想辦法。華中(zhong)電(dian)(dian)(dian)(dian)力(li)調度(du)中(zhong)心(xin)配(pei)合國家(jia)電(dian)(dian)(dian)(dian)力(li)調度(du)通信中(zhong)心(xin)，進(jin)行了大量(liang)的(de)分(fen)(fen)析計(ji)算，在(zai)最大限度(du)消除對電(dian)(dian)(dian)(dian)網(wang)(wang)安(an)全穩(wen)定水平(ping)影響的(de)情況下(xia)，針對三峽機組在(zai)開(kai)啟21臺及(ji)以下(xia)、22~23臺、24臺及(ji)以上三種狀態(tai)下(xia)的(de)電(dian)(dian)(dian)(dian)力(li)送(song)出(chu)(chu)，為(wei)電(dian)(dian)(dian)(dian)網(wang)(wang)設計(ji)了不同的(de)運行方式。
據(ju)預(yu)測，華中電網將(jiang)在6月(yue)底(di)或7月(yue)初迎來(lai)三峽(xia)電站滿發的考驗。
