9月26日(ri)，國家電網(wang)有限公(gong)司兩項(xiang)領先世(shi)界的(de)開(kai)創(chuang)性工程準東—皖南±1100千伏特(te)高(gao)壓直流輸電工程、蘇通1000千伏特(te)高(gao)壓交流GIL綜合(he)管廊(lang)工程投運，以優異成(cheng)績向中華(hua)人民共和國成(cheng)立(li)70周年獻禮。

準東(dong)—皖南、蘇通GIL綜(zong)合管廊工(gong)程，是推動我(wo)國(guo)(guo)能(neng)(neng)源結構調整和全面(mian)建(jian)成小康(kang)社會(hui)的(de)(de)(de)重(zhong)(zhong)點(dian)工(gong)程，在我(wo)國(guo)(guo)電力(li)(li)工(gong)業發展(zhan)史上具有(you)重(zhong)(zhong)要的(de)(de)(de)里程碑(bei)意義(yi)。兩項工(gong)程均占據(ju)了(le)當今世界輸電技(ji)術(shu)各自領域的(de)(de)(de)制(zhi)高點(dian)，推動我(wo)國(guo)(guo)電工(gong)裝備制(zhi)造能(neng)(neng)力(li)(li)實現了(le)新的(de)(de)(de)飛(fei)躍，使(shi)我(wo)國(guo)(guo)西電東(dong)送(song)和能(neng)(neng)源大(da)范(fan)圍優化(hua)(hua)配置(zhi)能(neng)(neng)力(li)(li)實現了(le)重(zhong)(zhong)要提(ti)升。工(gong)程投運后，清(qing)潔電力(li)(li)將更加高效地匯入華東(dong)特(te)高壓交流環網，對(dui)于優化(hua)(hua)能(neng)(neng)源配置(zhi)、保障電力(li)(li)供(gong)應(ying)、防治大(da)氣污染、拉動經濟增長、引領技(ji)術(shu)創新等具有(you)顯(xian)著的(de)(de)(de)綜(zong)合效益和長遠的(de)(de)(de)戰略意義(yi)。

準東—皖南(nan)工(gong)(gong)(gong)(gong)程(cheng)是目前世界(jie)上電(dian)壓等級最(zui)高、輸(shu)(shu)(shu)送(song)容量最(zui)大、輸(shu)(shu)(shu)電(dian)距離最(zui)遠、技術水平最(zui)先進(jin)的直流(liu)輸(shu)(shu)(shu)電(dian)工(gong)(gong)(gong)(gong)程(cheng)。工(gong)(gong)(gong)(gong)程(cheng)起點位(wei)(wei)于新疆維吾爾自治區昌吉回(hui)族自治州，終點位(wei)(wei)于安徽省宣城市，途(tu)經新疆、甘肅、寧夏、陜(shan)西、河南(nan)、安徽6省（區），輸(shu)(shu)(shu)送(song)容量1200萬(wan)(wan)千瓦，線路全長3324公里(li)。工(gong)(gong)(gong)(gong)程(cheng)實現了直流(liu)電(dian)壓、輸(shu)(shu)(shu)送(song)容量、交流(liu)網側電(dian)壓的全面提升，經濟輸(shu)(shu)(shu)電(dian)距離提升至(zhi)3000-5000公里(li)。工(gong)(gong)(gong)(gong)程(cheng)投運(yun)后，具備年送(song)電(dian)600-850億(yi)千瓦時的能(neng)力，將有效緩解華(hua)東地區中長期電(dian)力供需矛盾，可使(shi)華(hua)東地區每年減(jian)少燃(ran)煤約3800萬(wan)(wan)噸。同(tong)時，工(gong)(gong)(gong)(gong)程(cheng)將有力促(cu)進(jin)西部、北部能(neng)源(yuan)基地開發(fa)與外送(song)，擴(kuo)大清潔能(neng)源(yuan)消納范(fan)圍(wei)。

蘇通(tong)GIL綜合管廊工(gong)程(cheng)是世(shi)界上首次在(zai)重要輸(shu)電(dian)(dian)通(tong)道中采用特高壓GIL技(ji)術(shu)(shu)，是目前世(shi)界上電(dian)(dian)壓等級最(zui)(zui)高、輸(shu)送容量最(zui)(zui)大、技(ji)術(shu)(shu)水平最(zui)(zui)高的(de)(de)超長距離GIL創(chuang)新工(gong)程(cheng)。工(gong)程(cheng)是淮南(nan)(nan)—南(nan)(nan)京—上海(hai)1000千伏特高壓交流工(gong)程(cheng)的(de)(de)組(zu)成部分之一，工(gong)程(cheng)起(qi)于北岸(an)（南(nan)(nan)通(tong)）引接站，止于南(nan)(nan)岸(an)（蘇州(zhou)）引接站，GIL管線(xian)總長近35公里(li)。工(gong)程(cheng)在(zai)世(shi)界上率先采用了(le)特高壓GIL輸(shu)電(dian)(dian)全套技(ji)術(shu)(shu)，為跨江、跨海(hai)和人口(kou)密集地區(qu)(qu)的(de)(de)先進緊湊(cou)型輸(shu)電(dian)(dian)儲備了(le)技(ji)術(shu)(shu)。工(gong)程(cheng)投運(yun)以后，華東(dong)特高壓交流環(huan)網(wang)(wang)將實現合環(huan)運(yun)行，華東(dong)電(dian)(dian)網(wang)(wang)受電(dian)(dian)能力大幅提升(sheng)，每(mei)年可以減(jian)少發電(dian)(dian)用煤1.7億(yi)噸，減(jian)排二(er)氧(yang)化碳(tan)3.1億(yi)噸，顯著(zhu)改(gai)善(shan)華東(dong)地區(qu)(qu)環(huan)境質量。

新中(zhong)國(guo)成(cheng)(cheng)立70年(nian)來，我國(guo)電(dian)(dian)力發展取得舉世(shi)矚(zhu)目的(de)成(cheng)(cheng)就。國(guo)家電(dian)(dian)網(wang)已(yi)累計建成(cheng)(cheng)“10交11直(zhi)”特(te)高壓(ya)工(gong)程(cheng)，在建“4交2直(zhi)”特(te)高壓(ya)工(gong)程(cheng)，累計送電(dian)(dian)超過1.3萬億(yi)千瓦時(shi),成(cheng)(cheng)為(wei)全(quan)(quan)球并網(wang)裝機規模最(zui)(zui)大、電(dian)(dian)壓(ya)等級最(zui)(zui)高、資源配置能力最(zui)(zui)強、安全(quan)(quan)水平最(zui)(zui)好(hao)的(de)特(te)大型電(dian)(dian)網(wang)。
