1月10日，由西(xi)北(bei)電網公司(si)牽頭(tou)完(wan)成的《750千伏(fu)同塔雙(shuang)回緊(jin)湊(cou)型交流輸電線路(lu)關鍵技(ji)術(shu)研(yan)究(jiu)》通過(guo)國(guo)家電網公司(si)評審驗收。評審意見認為，該項目研(yan)究(jiu)成果達到(dao)國(guo)際領先(xian)水(shui)平，為西(xi)北(bei)高(gao)海(hai)拔地區750千伏(fu)緊(jin)湊(cou)型輸電線路(lu)建設提供了(le)技(ji)術(shu)依據，對(dui)加快西(xi)北(bei)750千伏(fu)電網建設、提高(gao)電網安(an)全經濟運行水(shui)平具有重要(yao)意義(yi)，建議盡快推(tui)廣應(ying)用(yong)。
針對電壓等(deng)(deng)級高(gao)、海(hai)拔高(gao)、系(xi)統復雜（包(bao)含大規模風電場、可控高(gao)抗(kang)、串補等(deng)(deng)）、線(xian)路(lu)較長（1200千(qian)米(mi)）等(deng)(deng)特點(dian)，開展750千(qian)伏緊(jin)湊(cou)型關(guan)鍵技(ji)術研究在國(guo)際上尚屬首(shou)(shou)次。該項(xiang)(xiang)目(mu)(mu)列入國(guo)家(jia)電網公司2007年(nian)(nian)重(zhong)點(dian)科技(ji)項(xiang)(xiang)目(mu)(mu)，由西北電網公司牽頭組(zu)織(zhi)，9家(jia)科研單位(wei)共同(tong)參加，項(xiang)(xiang)目(mu)(mu)研究歷時近1年(nian)(nian)半(ban)，經過相關(guan)單位(wei)通(tong)力(li)合作、配合研究，克服許多重(zhong)大技(ji)術挑(tiao)戰(zhan)和問題，全(quan)面完成了研究任務，使我國(guo)成為掌握(wo)高(gao)海(hai)拔地(di)區750千(qian)伏同(tong)塔雙回緊(jin)湊(cou)型交(jiao)流輸電關(guan)鍵技(ji)術的(de)唯一(yi)國(guo)家(jia)。應用(yong)這一(yi)研究成果，2009年(nian)(nian)1月9日，國(guo)內首(shou)(shou)條750千(qian)伏同(tong)塔雙回輸變電工程蘭(lan)州東～平涼～乾縣工程全(quan)線(xian)架(jia)通(tong)，實現了西北750千(qian)伏電網裝(zhuang)備技(ji)術水平上臺階。
按照(zhao)特高(gao)壓電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)發展(zhan)理念，西(xi)北(bei)(bei)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)公(gong)司加快(kuai)750千伏電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)建設，一(yi)個覆蓋(gai)國(guo)土面(mian)積(ji)三(san)分之(zhi)一(yi)、橫向(xiang)跨越4000余公(gong)里、連(lian)接五省(sheng)（區）和西(xi)藏的超大(da)(da)型750千伏送端電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)即將形成(cheng)(cheng)，并與未來(lai)“三(san)華(hua)”電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)相連(lian)。電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)發展(zhan)方式轉變，電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)全(quan)面(mian)快(kuai)速發展(zhan)，迫(po)切需要科技(ji)(ji)創新的支(zhi)撐(cheng)。西(xi)北(bei)(bei)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)公(gong)司貫(guan)徹(che)“一(yi)流四(si)大(da)(da)”科技(ji)(ji)發展(zhan)戰(zhan)略(lve)，圍繞750千伏電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)建設發展(zhan)、大(da)(da)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)安全(quan)穩定運行(xing)，加大(da)(da)重點領域科技(ji)(ji)投(tou)入，攻克(ke)關鍵(jian)技(ji)(ji)術難題，為(wei)(wei)建設運行(xing)750千伏主網(wang)(wang)(wang)(wang)架提供支(zhi)撐(cheng)。2008年，9項科技(ji)(ji)成(cheng)(cheng)果獲國(guo)家電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)公(gong)司、陜(shan)西(xi)省(sheng)科技(ji)(ji)進步獎項，獲獎數量為(wei)(wei)歷(li)年之(zhi)最(zui)；專利申報實現歷(li)史性突破，獲得國(guo)家專利授權26項。成(cheng)(cheng)立西(xi)北(bei)(bei)風(feng)(feng)(feng)電(dian)(dian)(dian)(dian)(dian)研究中心，舉辦全(quan)國(guo)性風(feng)(feng)(feng)電(dian)(dian)(dian)(dian)(dian)技(ji)(ji)術論壇，開展(zhan)調(diao)度測風(feng)(feng)(feng)網(wang)(wang)(wang)(wang)絡規(gui)劃研究，在甘肅酒泉建成(cheng)(cheng)投(tou)運了3基用于電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)調(diao)度的示范測風(feng)(feng)(feng)塔，電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)調(diao)度測風(feng)(feng)(feng)網(wang)(wang)(wang)(wang)絡進入實際應(ying)用階(jie)段，為(wei)(wei)推動西(xi)北(bei)(bei)風(feng)(feng)(feng)電(dian)(dian)(dian)(dian)(dian)規(gui)模發展(zhan)奠定了基礎。
