12月2日(ri)，國家“十二(er)五”重點工(gong)程(cheng)糯扎渡(du)電(dian)站送(song)電(dian)廣(guang)東(dong)±800千(qian)(qian)(qian)伏直(zhi)流輸電(dian)工(gong)程(cheng)和(he)溪洛渡(du)右岸電(dian)站送(song)電(dian)廣(guang)東(dong)±500千(qian)(qian)(qian)伏同塔雙回直(zhi)流輸電(dian)工(gong)程(cheng)（簡稱 “兩(liang)渡(du)工(gong)程(cheng)”）開工(gong)儀(yi)式(shi)在云南普洱(er)舉行。這是南方(fang)電(dian)網“十二(er)五”期間(jian)投資最(zui)(zui)多、輸電(dian)容量最(zui)(zui)大、輸送(song)距離最(zui)(zui)長的電(dian)網建設項目，將(jiang)新增輸電(dian)容量1140萬千(qian)(qian)(qian) 瓦，約(yue)為(wei)目前南方(fang)電(dian)網西電(dian)東(dong)送(song)規模(mo)的一半。 

      工程建(jian)成后，每年(nian)將(jiang)有400多億(yi)千(qian)瓦(wa)(wa)時清潔水(shui)電(dian)送(song)往珠(zhu)三角(jiao)符合(he)密(mi)集(ji)地(di)(di)區，減少二氧化碳排放(fang)約3400萬噸(dun)，這對于西南地(di)(di)區水(shui)電(dian)大(da)規模開(kai)發利用、促進 能源資源在更大(da)范圍內實(shi)現優化配置、促進五省(sheng)區優勢互(hu)補和協調發展具(ju)有重要的意義。同時，南方電(dian)網也將(jiang)形成“八(ba)交(jiao)八(ba)直(zhi)”共(gong)16條500千(qian)伏(fu)及(ji)以上的西電(dian)東 送(song)大(da)通道(dao)，送(song)電(dian)規模預(yu)計超(chao)過(guo)達到(dao)4300萬千(qian)瓦(wa)(wa)。

      國家能(neng)源局電力(li)司副司長秦(qin)志(zhi)軍告訴記者，南(nan)方地(di)區(qu)西(xi)(xi)部水電資源豐(feng)富，東(dong)部經(jing)濟發達、負荷(he)需求旺盛，將西(xi)(xi)南(nan)地(di)區(qu)的清潔(jie)水電輸(shu)送至(zhi)東(dong)部沿海發達地(di)區(qu)是今 后滿(man)足南(nan)方地(di)區(qu)資源、經(jing)濟發展的重要手段。“兩(liang)渡”直流輸(shu)電工程的開工建設對于(yu)加快(kuai)金(jin)沙江(jiang)、瀾滄江(jiang)水電開發、促進(jin)西(xi)(xi)電東(dong)送戰(zhan)略進(jin)一步實施、實現東(dong)西(xi)(xi)部資源 互補、能(neng)源優(you)化配置，保障(zhang)南(nan)方各(ge)省區(qu)電力(li)供應(ying)具有重要意(yi)義。

     據了(le)解(jie)，南(nan)(nan)方電(dian)(dian)(dian)(dian)網(wang)公司一直積極推(tui)(tui)動國家西(xi)電(dian)(dian)(dian)(dian)東送(song)戰略(lve)實施，目前已形(xing)成“八交(jiao)(jiao)五直”共13條西(xi)電(dian)(dian)(dian)(dian)東送(song)大通道，最大輸送(song)能力超(chao)過2400萬(wan)千(qian)瓦(wa)(wa)，西(xi)電(dian)(dian)(dian)(dian)東 送(song)電(dian)(dian)(dian)(dian)量(liang)年(nian)均增長15.4%，初步(bu)實現(xian)了(le)階(jie)段性的東西(xi)共贏。南(nan)(nan)方電(dian)(dian)(dian)(dian)網(wang)公司董(dong)事(shi)長趙(zhao)建(jian)國稱，“十二五”期(qi)間，南(nan)(nan)方電(dian)(dian)(dian)(dian)網(wang)公司將繼續(xu)加大西(xi)電(dian)(dian)(dian)(dian)東送(song)力度，2015年(nian) 西(xi)電(dian)(dian)(dian)(dian)東送(song)總規(gui)(gui)模將達到4300萬(wan)千(qian)瓦(wa)(wa)，主要以增送(song)云南(nan)(nan)水電(dian)(dian)(dian)(dian)為(wei)主。同時加強(qiang)跨(kua)省(sheng)區能源(yuan)規(gui)(gui)劃(hua)、西(xi)電(dian)(dian)(dian)(dian)東送(song)交(jiao)(jiao)易機制等(deng)重大課題研究(jiu)，密切配合各(ge)級政府，加快推(tui)(tui)動建(jian) 立更為(wei)完善、合理的西(xi)電(dian)(dian)(dian)(dian)東送(song)電(dian)(dian)(dian)(dian)價形(xing)成機制和交(jiao)(jiao)易機制，促進西(xi)電(dian)(dian)(dian)(dian)東送(song)可持續(xu)發(fa)展。

    “兩渡工程”屬國家十二五西電東送重大能源建設項目和自主化示范工程，線路總長度4000余公里。糯扎渡電站送電廣東±800千伏直流輸電工程，西 起云南省普洱市，東至廣東省江門市，穿越云南、廣西、廣東三省區，線路全長1451公里，額定輸送容量雙極500萬千瓦，額定電壓±800千伏。該工程是 南方電網公司繼建成±800千伏云廣特高壓直流示范性工程后，負責建設的第二條特高壓直流輸電工程，工程建設將在借鑒特高壓成熟技術的基礎上，進一步提高 設備國產化比例，尤其是以往進口設備為主的直流場核心設備的國產化比例將超過40%，促進國內裝備制造業的發展。溪(xi)洛渡右岸電(dian)站送電(dian)廣(guang)東(dong)(dong)±500千伏同塔 雙回直流輸(shu)電(dian)工程(cheng)，西起云(yun)南省昭通市(shi)，東(dong)(dong)至廣(guang)東(dong)(dong)省廣(guang)州(zhou)市(shi)，穿越云(yun)南、貴(gui)州(zhou)、廣(guang)西、廣(guang)東(dong)(dong)四省區，線路合計(ji)2572公(gong)里，總輸(shu)送容量640萬千瓦，額(e)定電(dian) 壓(ya)±500千伏。該工程(cheng)采(cai)用的同塔雙回500千伏直流輸(shu)電(dian)的送電(dian)方式，既節(jie)省了(le)投(tou)資(zi)規模又節(jie)約了(le)土地資(zi)源，其設備國(guo)產化率也基(ji)本達到100%。
