　　12月26日，由我(wo)國自(zi)主設計、自(zi)主建設的(de)(de)向家壩-上(shang)海±800千(qian)(qian)伏(fu)(fu)特高(gao)壓(ya)(ya)直(zhi)(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)示(shi)范工(gong)程(cheng)全線(xian)升壓(ya)(ya)至直(zhi)(zhi)(zhi)流(liu)(liu)800千(qian)(qian)伏(fu)(fu)，標(biao)志著(zhu)目(mu)前世(shi)界(jie)(jie)上(shang)輸(shu)送(song)容量最大(da)、送(song)電(dian)(dian)(dian)(dian)距離最遠、技術水平最先進、電(dian)(dian)(dian)(dian)壓(ya)(ya)等級最高(gao)的(de)(de)直(zhi)(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)工(gong)程(cheng)全線(xian)帶(dai)電(dian)(dian)(dian)(dian)成功。該工(gong)程(cheng)額(e)定(ding)電(dian)(dian)(dian)(dian)壓(ya)(ya)±800千(qian)(qian)伏(fu)(fu)、額(e)定(ding)電(dian)(dian)(dian)(dian)流(liu)(liu)4000安培(pei)，輸(shu)送(song)功率可達700萬千(qian)(qian)瓦級，是引領世(shi)界(jie)(jie)直(zhi)(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)技術發展的(de)(de)創(chuang)新工(gong)程(cheng)，在世(shi)界(jie)(jie)上(shang)率先實現特高(gao)壓(ya)(ya)直(zhi)(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)(dian)流(liu)(liu)雙(shuang)提升、雙(shuang)突破，代表世(shi)界(jie)(jie)直(zhi)(zhi)(zhi)流(liu)(liu)輸(shu)電(dian)(dian)(dian)(dian)技術的(de)(de)最高(gao)水平，也(ye)標(biao)志著(zhu)國家電(dian)(dian)(dian)(dian)網(wang)(wang)全面進入(ru)特高(gao)壓(ya)(ya)交(jiao)直(zhi)(zhi)(zhi)流(liu)(liu)混合(he)電(dian)(dian)(dian)(dian)網(wang)(wang)時期。

　　該(gai)工(gong)程(cheng)西起四(si)川(chuan)向(xiang)家壩(ba)復龍換(huan)流站，東至(zhi)上海(hai)奉賢換(huan)流站，全(quan)長約(yue)1907公里，途經(jing)8個省(sheng)市，4次(ci)跨(kua)越長江，對(dui)于實(shi)現西南水(shui)電(dian)(dian)能(neng)源基地(di)大規(gui)模開發(fa)(fa)和經(jing)濟(ji)高(gao)效送出，進(jin)一(yi)步促進(jin)我國清潔能(neng)源快速(su)發(fa)(fa)展(zhan)，滿足東部地(di)區日益增長的(de)負荷發(fa)(fa)展(zhan)需要，改善能(neng)源結構，促進(jin)節(jie)(jie)能(neng)減(jian)排(pai)，具有重要意義和深遠影響。通過(guo)該(gai)工(gong)程(cheng)每年可(ke)向(xiang)上海(hai)輸送四(si)川(chuan)清潔水(shui)電(dian)(dian)350億(yi)千瓦時，相當于目前(qian)上海(hai)市全(quan)年用電(dian)(dian)量的(de)三(san)分(fen)之一(yi)，比(bi)在上海(hai)直接建設火力(li)發(fa)(fa)電(dian)(dian)廠，每年可(ke)節(jie)(jie)省(sheng)原煤(mei)1600萬噸，減(jian)排(pai)二氧化碳(tan)超過(guo)2600萬噸，節(jie)(jie)能(neng)減(jian)排(pai)意義重大。
