9月26日(ri)，國家電(dian)網有限(xian)公司(si)兩項領先世(shi)界的開(kai)創性工程準東—皖南±1100千伏特(te)高壓(ya)直流輸電(dian)工程、蘇(su)通1000千伏特(te)高壓(ya)交(jiao)流GIL綜合管廊工程投運，以優異成(cheng)績向中華人(ren)民共和國成(cheng)立70周年獻禮。

準東—皖南、蘇通GIL綜(zong)合(he)管廊工(gong)(gong)(gong)(gong)(gong)程，是推(tui)動我(wo)國(guo)能源(yuan)結構調整和全面建成(cheng)小康社會的(de)重點工(gong)(gong)(gong)(gong)(gong)程，在我(wo)國(guo)電力工(gong)(gong)(gong)(gong)(gong)業發展史上具有重要(yao)的(de)里程碑意義(yi)。兩項工(gong)(gong)(gong)(gong)(gong)程均占(zhan)據了當今世界輸電技術(shu)各(ge)自領域(yu)的(de)制(zhi)高(gao)點，推(tui)動我(wo)國(guo)電工(gong)(gong)(gong)(gong)(gong)裝(zhuang)備制(zhi)造能力實(shi)現了新(xin)的(de)飛(fei)躍，使我(wo)國(guo)西(xi)電東送和能源(yuan)大(da)范圍優化(hua)(hua)配(pei)置能力實(shi)現了重要(yao)提(ti)升。工(gong)(gong)(gong)(gong)(gong)程投運后，清潔電力將更加高(gao)效地匯入華東特(te)高(gao)壓交流環網(wang)，對于優化(hua)(hua)能源(yuan)配(pei)置、保障電力供應、防治大(da)氣污染、拉動經濟(ji)增長(chang)、引(yin)領技術(shu)創新(xin)等具有顯著(zhu)的(de)綜(zong)合(he)效益和長(chang)遠的(de)戰略意義(yi)。

準東—皖南工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)是目前世界上電(dian)壓(ya)等級(ji)最(zui)高、輸(shu)送容(rong)量(liang)最(zui)大(da)、輸(shu)電(dian)距離最(zui)遠、技術水(shui)平最(zui)先進的(de)(de)直(zhi)流(liu)輸(shu)電(dian)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)。工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)起(qi)點(dian)位于新(xin)疆維(wei)吾爾自治(zhi)(zhi)區(qu)(qu)昌吉回族自治(zhi)(zhi)州，終點(dian)位于安徽省宣城市，途經新(xin)疆、甘肅(su)、寧夏、陜西、河南、安徽6省（區(qu)(qu)），輸(shu)送容(rong)量(liang)1200萬千瓦，線路全(quan)長(chang)3324公(gong)里。工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)實現了直(zhi)流(liu)電(dian)壓(ya)、輸(shu)送容(rong)量(liang)、交流(liu)網側(ce)電(dian)壓(ya)的(de)(de)全(quan)面提升(sheng)，經濟輸(shu)電(dian)距離提升(sheng)至3000-5000公(gong)里。工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)投運后，具備年送電(dian)600-850億千瓦時的(de)(de)能(neng)力(li)，將(jiang)有(you)效緩(huan)解(jie)華(hua)東地(di)(di)區(qu)(qu)中長(chang)期電(dian)力(li)供需矛盾，可使華(hua)東地(di)(di)區(qu)(qu)每(mei)年減少燃煤約(yue)3800萬噸。同時，工(gong)(gong)(gong)程(cheng)(cheng)(cheng)(cheng)將(jiang)有(you)力(li)促(cu)進西部(bu)、北(bei)部(bu)能(neng)源基(ji)地(di)(di)開發(fa)與外(wai)送，擴大(da)清潔(jie)能(neng)源消納范圍。

蘇通GIL綜合(he)管(guan)廊工程(cheng)(cheng)是(shi)世(shi)界上(shang)首(shou)次在重要(yao)輸(shu)(shu)(shu)電(dian)(dian)(dian)通道(dao)中(zhong)采用特高(gao)(gao)(gao)壓(ya)GIL技(ji)術(shu)，是(shi)目(mu)前世(shi)界上(shang)電(dian)(dian)(dian)壓(ya)等級最高(gao)(gao)(gao)、輸(shu)(shu)(shu)送容量(liang)最大、技(ji)術(shu)水平最高(gao)(gao)(gao)的超長距(ju)離GIL創(chuang)新工程(cheng)(cheng)。工程(cheng)(cheng)是(shi)淮南—南京—上(shang)海1000千伏特高(gao)(gao)(gao)壓(ya)交(jiao)流工程(cheng)(cheng)的組成部分之一，工程(cheng)(cheng)起于北岸（南通）引接(jie)站，止于南岸（蘇州(zhou)）引接(jie)站，GIL管(guan)線總長近35公里。工程(cheng)(cheng)在世(shi)界上(shang)率(lv)先(xian)(xian)采用了特高(gao)(gao)(gao)壓(ya)GIL輸(shu)(shu)(shu)電(dian)(dian)(dian)全(quan)套(tao)技(ji)術(shu)，為(wei)跨江、跨海和人口密集地(di)區(qu)的先(xian)(xian)進緊湊型(xing)輸(shu)(shu)(shu)電(dian)(dian)(dian)儲備了技(ji)術(shu)。工程(cheng)(cheng)投運(yun)以(yi)后，華(hua)(hua)東(dong)(dong)特高(gao)(gao)(gao)壓(ya)交(jiao)流環(huan)網將實現(xian)合(he)環(huan)運(yun)行，華(hua)(hua)東(dong)(dong)電(dian)(dian)(dian)網受電(dian)(dian)(dian)能(neng)力大幅提(ti)升，每(mei)年可(ke)以(yi)減少(shao)發(fa)電(dian)(dian)(dian)用煤1.7億噸(dun)，減排二氧化碳3.1億噸(dun)，顯著改善華(hua)(hua)東(dong)(dong)地(di)區(qu)環(huan)境質(zhi)量(liang)。
