記者從國網省(sheng)(sheng)電(dian)力公(gong)(gong)(gong)司了(le)解到，今年(nian)以來，為促進(jin)陜(shan)(shan)西“能(neng)源大省(sheng)(sheng)”向“電(dian)力大省(sheng)(sheng)”的(de)(de)轉變，經過陜(shan)(shan)西公(gong)(gong)(gong)司多次對我(wo)省(sheng)(sheng)首個“陜(shan)(shan)電(dian)外送”特(te)高壓工(gong)程(cheng)(cheng)榆橫--濰坊1000千伏特(te)高壓交流輸變電(dian)工(gong)程(cheng)(cheng)陜(shan)(shan)西段的(de)(de)啟動、電(dian)力線路(lu)架線、跨越(yue)高速(su)(su)公(gong)(gong)(gong)路(lu)、鐵路(lu)等重要跨越(yue)的(de)(de)組(zu)織部署驗收工(gong)作，于今年(nian)6月27日全(quan)線建成竣(jun)(jun)工(gong)。該工(gong)程(cheng)(cheng)的(de)(de)竣(jun)(jun)工(gong)，對推動陜(shan)(shan)北能(neng)源化工(gong)基地(di)建設、大型煤電(dian)基地(di)的(de)(de)集約化開發、新(xin)能(neng)源快速(su)(su)發展具有重要意(yi)義。

陜西是(shi)能(neng)源(yuan)大省(sheng)(sheng)，約占全(quan)國能(neng)源(yuan)生產(chan)總(zong)(zong)(zong)量(liang)(liang)的8.8%，煤(mei)(mei)炭(tan)、太(tai)陽能(neng)、風(feng)能(neng)、水電(dian)資(zi)源(yuan)十分豐富。從全(quan)省(sheng)(sheng)能(neng)源(yuan)供求(qiu)來(lai)看(kan)，需求(qiu)量(liang)(liang)僅占總(zong)(zong)(zong)生產(chan)量(liang)(liang)的30%左(zuo)右，陜西煤(mei)(mei)炭(tan)、水電(dian)等資(zi)源(yuan)總(zong)(zong)(zong)計可支撐電(dian)力裝機達1.4億(yi)千瓦(wa)。2015年(nian)，全(quan)省(sheng)(sheng)發(fa)電(dian)總(zong)(zong)(zong)裝機達到(dao)3820萬千瓦(wa)，到(dao)2020年(nian)，預計全(quan)省(sheng)(sheng)發(fa)電(dian)總(zong)(zong)(zong)裝機將達到(dao)5760萬千瓦(wa)，在滿(man)足(zu)省(sheng)(sheng)內用電(dian)需求(qiu)的同時(shi)，還將有(you)大量(liang)(liang)的外送(song)電(dian)力空間。

在(zai)(zai)“十三五”期間，榆橫-濰坊、陜(shan)(shan)(shan)(shan)(shan)(shan)北-武(wu)漢(han)、隴彬-徐州(zhou)等特高壓工程將(jiang)相(xiang)繼在(zai)(zai)陜(shan)(shan)(shan)(shan)(shan)(shan)西落點送(song)出。特高壓工程的建設(she)，將(jiang)充(chong)分發揮(hui)陜(shan)(shan)(shan)(shan)(shan)(shan)西的區位優勢，助力(li)陜(shan)(shan)(shan)(shan)(shan)(shan)西從能源(yuan)大(da)(da)省(sheng)向(xiang)電(dian)力(li)大(da)(da)省(sheng)轉變。預計到2020年，陜(shan)(shan)(shan)(shan)(shan)(shan)西將(jiang)建設(she)9項特高壓工程，新(xin)增外送(song)電(dian)能力(li)將(jiang)達到3611萬千(qian)瓦(wa)，由(you)現在(zai)(zai)占全國(guo)的4%提升至10%，進一(yi)步加大(da)(da)陜(shan)(shan)(shan)(shan)(shan)(shan)西電(dian)力(li)外送(song)，加強互(hu)聯互(hu)通。

榆橫工程(cheng)陜西(xi)(xi)段新建榆橫1000千伏開關站，站址位(wei)于榆林(lin)市橫山縣塔(ta)(ta)(ta)灣鎮，途經陜西(xi)(xi)、山西(xi)(xi)、河(he)北、山東4省，全(quan)線雙(shuang)回路架設，全(quan)長2×1049公里(li)，是世(shi)界上迄今(jin)為止輸(shu)電距離最(zui)長的特高壓交流工程(cheng)，承擔著華北東部(bu)(bu)地區重(zhong)要送電任(ren)務(wu)。該工程(cheng)陜西(xi)(xi)境內約2×149.5千米(mi)，途經橫山縣、子洲(zhou)縣、綏德縣、清(qing)澗縣四縣，共計鐵塔(ta)(ta)(ta)491基。單回路架設長度 2×142.8千米(mi)，同塔(ta)(ta)(ta)雙(shuang)回路架設長度2×6.7千米(mi)，單回路段鐵塔(ta)(ta)(ta)全(quan)部(bu)(bu)采用(yong)角鋼(gang)塔(ta)(ta)(ta)，同塔(ta)(ta)(ta)雙(shuang)回路段鐵塔(ta)(ta)(ta)全(quan)部(bu)(bu)采用(yong)鋼(gang)管塔(ta)(ta)(ta)。占(zhan)地面(mian)積10.56公頃，工程(cheng)靜態投(tou)資103588萬元，動態投(tou)資105932萬元。

目前，榆橫1000千伏開關(guan)站1000千伏配電(dian)設(she)備(bei)耐壓及局放試驗(yan)全(quan)部順利通過(guo)。陜西段全(quan)線施(shi)工(gong)已全(quan)部結束，其中站區建(jian)筑物、站用交直(zhi)流系(xi)(xi)(xi)統(tong)(tong)(tong)、物防系(xi)(xi)(xi)統(tong)(tong)(tong)、高抗消(xiao)防系(xi)(xi)(xi)統(tong)(tong)(tong)，一次設(she)備(bei)驗(yan)收完成。

據記(ji)者(zhe)了解，榆橫-濰坊1000千伏特高(gao)壓(ya)(ya)輸變電工(gong)程是陜(shan)西(xi)首條跨(kua)越陜(shan)、晉(jin)、冀、魯四(si)省的能源輸送特高(gao)壓(ya)(ya)線路，是國家大氣污染防治行(xing)動計劃(hua)“四(si)交(jiao)四(si)直(zhi) ”特高(gao)壓(ya)(ya)工(gong)程中第5條獲得核(he)準開(kai)工(gong)的輸電通道，是華北特高(gao)壓(ya)(ya)交(jiao)直(zhi)流主網架的重要(yao)組成部分，該工(gong)程的建成投運(yun)將促進(jin)陜(shan)西(xi)與(yu)山西(xi)能源基地(di)開(kai)發(fa)(fa)與(yu)外送，有(you)效緩解中東部電力緊(jin)張(zhang)局面，對(dui)推(tui)動陜(shan)北、晉(jin)中煤炭基地(di)發(fa)(fa)展，提高(gao)煤炭、發(fa)(fa)電行(xing)業集約化發(fa)(fa)展水平，滿足京津(jin)冀地(di)區用電負(fu)荷增長(chang)需求，落實(shi)國家大氣污染防治行(xing)動計劃(hua)，改善(shan)生態環(huan)境質(zhi)量均具有(you)重要(yao)的意義。
