　　1月10日，由西北(bei)電(dian)網(wang)公司牽頭(tou)完成(cheng)的(de)《750千(qian)伏同塔(ta)雙回緊(jin)湊(cou)型交流輸(shu)電(dian)線(xian)路(lu)關鍵技術(shu)研究》通過國家電(dian)網(wang)公司評審驗(yan)收。評審意見認為(wei)，該項目研究成(cheng)果達到國際(ji)領先水平，為(wei)西北(bei)高海拔地(di)區750千(qian)伏緊(jin)湊(cou)型輸(shu)電(dian)線(xian)路(lu)建設提供了技術(shu)依據，對(dui)加(jia)快(kuai)(kuai)西北(bei)750千(qian)伏電(dian)網(wang)建設、提高電(dian)網(wang)安全經濟(ji)運行水平具有(you)重要意義，建議(yi)盡快(kuai)(kuai)推廣應用。

　　針對電(dian)(dian)壓等(deng)級高(gao)、海拔高(gao)、系統復雜（包含大(da)規模風電(dian)(dian)場、可控高(gao)抗、串補等(deng)）、線路(lu)較長（1200千(qian)米）等(deng)特(te)點(dian)，開展750千(qian)伏(fu)(fu)緊湊(cou)型關鍵技(ji)術(shu)研(yan)(yan)(yan)究在國(guo)(guo)際上尚屬首(shou)(shou)次(ci)。該項目(mu)列(lie)入國(guo)(guo)家(jia)電(dian)(dian)網公司(si)2007年(nian)(nian)重(zhong)點(dian)科技(ji)項目(mu)，由西北電(dian)(dian)網公司(si)牽頭組織，9家(jia)科研(yan)(yan)(yan)單(dan)(dan)位共(gong)同參(can)加，項目(mu)研(yan)(yan)(yan)究歷時近1年(nian)(nian)半，經過(guo)相關單(dan)(dan)位通(tong)(tong)力合作、配合研(yan)(yan)(yan)究，克服許多重(zhong)大(da)技(ji)術(shu)挑戰和問題(ti)，全(quan)面完成了(le)研(yan)(yan)(yan)究任務，使我國(guo)(guo)成為掌握(wo)高(gao)海拔地區(qu)750千(qian)伏(fu)(fu)同塔(ta)雙回(hui)緊湊(cou)型交流輸電(dian)(dian)關鍵技(ji)術(shu)的唯一(yi)國(guo)(guo)家(jia)。應用這(zhe)一(yi)研(yan)(yan)(yan)究成果，2009年(nian)(nian)1月(yue)9日，國(guo)(guo)內首(shou)(shou)條750千(qian)伏(fu)(fu)同塔(ta)雙回(hui)輸變電(dian)(dian)工(gong)程蘭州東～平(ping)涼～乾縣工(gong)程全(quan)線架通(tong)(tong)，實現了(le)西北750千(qian)伏(fu)(fu)電(dian)(dian)網裝(zhuang)備技(ji)術(shu)水平(ping)上臺階。

　　按照特(te)高壓電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)發(fa)展(zhan)(zhan)(zhan)理念，西(xi)(xi)(xi)北電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)公(gong)司加快750千(qian)伏(fu)電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)建(jian)(jian)設，一個覆(fu)蓋國土(tu)面積三分之(zhi)一、橫向跨越4000余公(gong)里、連接五省（區(qu)）和(he)西(xi)(xi)(xi)藏(zang)的(de)(de)超大(da)型(xing)750千(qian)伏(fu)送端電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)即將(jiang)形成，并與未來“三華”電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)相連。電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)發(fa)展(zhan)(zhan)(zhan)方式轉變，電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)全面快速(su)發(fa)展(zhan)(zhan)(zhan)，迫切(qie)需要科技(ji)(ji)創新(xin)的(de)(de)支撐。西(xi)(xi)(xi)北電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)公(gong)司貫徹“一流四大(da)”科技(ji)(ji)發(fa)展(zhan)(zhan)(zhan)戰略，圍繞750千(qian)伏(fu)電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)建(jian)(jian)設發(fa)展(zhan)(zhan)(zhan)、大(da)電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)安全穩(wen)定(ding)運(yun)行(xing)，加大(da)重點領域(yu)科技(ji)(ji)投(tou)入(ru)，攻克關鍵技(ji)(ji)術難(nan)題，為(wei)建(jian)(jian)設運(yun)行(xing)750千(qian)伏(fu)主(zhu)網(wang)(wang)(wang)(wang)架提(ti)供支撐。2008年，9項(xiang)科技(ji)(ji)成果獲(huo)國家電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)公(gong)司、陜西(xi)(xi)(xi)省科技(ji)(ji)進步(bu)獎(jiang)項(xiang)，獲(huo)獎(jiang)數量(liang)為(wei)歷年之(zhi)最；專(zhuan)利申報(bao)實現歷史性突破，獲(huo)得國家專(zhuan)利授權(quan)26項(xiang)。成立西(xi)(xi)(xi)北風(feng)(feng)電(dian)(dian)(dian)研究中心(xin)，舉辦(ban)全國性風(feng)(feng)電(dian)(dian)(dian)技(ji)(ji)術論壇，開展(zhan)(zhan)(zhan)調(diao)度(du)測風(feng)(feng)網(wang)(wang)(wang)(wang)絡規劃研究，在甘(gan)肅(su)酒泉建(jian)(jian)成投(tou)運(yun)了3基用于電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)調(diao)度(du)的(de)(de)示范測風(feng)(feng)塔，電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)調(diao)度(du)測風(feng)(feng)網(wang)(wang)(wang)(wang)絡進入(ru)實際應用階(jie)段(duan)，為(wei)推動西(xi)(xi)(xi)北風(feng)(feng)電(dian)(dian)(dian)規模(mo)發(fa)展(zhan)(zhan)(zhan)奠定(ding)了基礎。
