　　1月10日，由西北(bei)電網公(gong)司(si)牽頭完成的《750千伏同塔雙回(hui)緊湊型(xing)交流輸(shu)電線路關(guan)鍵技術(shu)研究》通過國家(jia)電網公(gong)司(si)評(ping)審(shen)(shen)驗收。評(ping)審(shen)(shen)意見認為(wei)，該項目研究成果達(da)到(dao)國際領先水平，為(wei)西北(bei)高(gao)海拔地(di)區(qu)750千伏緊湊型(xing)輸(shu)電線路建設(she)(she)提(ti)供(gong)了(le)技術(shu)依(yi)據，對(dui)加快西北(bei)750千伏電網建設(she)(she)、提(ti)高(gao)電網安(an)全(quan)經(jing)濟(ji)運行水平具有(you)重要意義，建議盡快推廣應(ying)用。

　　針對電(dian)壓等(deng)級高、海拔(ba)高、系統復(fu)雜（包含大規(gui)模風(feng)電(dian)場(chang)、可(ke)控高抗、串補(bu)等(deng)）、線路(lu)較(jiao)長（1200千(qian)米）等(deng)特點(dian)，開展750千(qian)伏(fu)緊(jin)(jin)湊(cou)型(xing)關鍵技(ji)術(shu)(shu)研(yan)究在國際(ji)上(shang)(shang)尚(shang)屬首次(ci)。該項目(mu)(mu)列入國家(jia)電(dian)網(wang)公司(si)2007年(nian)重點(dian)科技(ji)項目(mu)(mu)，由(you)西北(bei)(bei)電(dian)網(wang)公司(si)牽(qian)頭組織，9家(jia)科研(yan)單(dan)位(wei)共同參加，項目(mu)(mu)研(yan)究歷時(shi)近1年(nian)半，經(jing)過相(xiang)關單(dan)位(wei)通(tong)力合(he)作、配(pei)合(he)研(yan)究，克服(fu)許多(duo)重大技(ji)術(shu)(shu)挑(tiao)戰(zhan)和問題(ti)，全(quan)面完成(cheng)了(le)研(yan)究任務，使我國成(cheng)為掌握高海拔(ba)地區750千(qian)伏(fu)同塔(ta)(ta)雙回緊(jin)(jin)湊(cou)型(xing)交流輸(shu)電(dian)關鍵技(ji)術(shu)(shu)的唯一國家(jia)。應用(yong)這(zhe)一研(yan)究成(cheng)果，2009年(nian)1月9日，國內首條(tiao)750千(qian)伏(fu)同塔(ta)(ta)雙回輸(shu)變電(dian)工(gong)程(cheng)蘭州(zhou)東～平(ping)涼～乾縣工(gong)程(cheng)全(quan)線架通(tong)，實現了(le)西北(bei)(bei)750千(qian)伏(fu)電(dian)網(wang)裝(zhuang)備技(ji)術(shu)(shu)水(shui)平(ping)上(shang)(shang)臺(tai)階(jie)。

　　按照特高(gao)壓電(dian)(dian)(dian)(dian)網(wang)(wang)發(fa)展理念(nian)，西(xi)(xi)北(bei)電(dian)(dian)(dian)(dian)網(wang)(wang)公司加快(kuai)750千(qian)伏電(dian)(dian)(dian)(dian)網(wang)(wang)建(jian)設(she)，一個(ge)覆(fu)蓋國(guo)土(tu)面積三分之一、橫向跨越4000余公里、連接五省（區）和西(xi)(xi)藏的超(chao)大型750千(qian)伏送端電(dian)(dian)(dian)(dian)網(wang)(wang)即將形成，并(bing)與未來“三華”電(dian)(dian)(dian)(dian)網(wang)(wang)相(xiang)連。電(dian)(dian)(dian)(dian)網(wang)(wang)發(fa)展方式轉變，電(dian)(dian)(dian)(dian)網(wang)(wang)全面快(kuai)速發(fa)展，迫切(qie)需要科(ke)技(ji)(ji)創新的支撐。西(xi)(xi)北(bei)電(dian)(dian)(dian)(dian)網(wang)(wang)公司貫徹“一流四(si)大”科(ke)技(ji)(ji)發(fa)展戰(zhan)略，圍繞750千(qian)伏電(dian)(dian)(dian)(dian)網(wang)(wang)建(jian)設(she)發(fa)展、大電(dian)(dian)(dian)(dian)網(wang)(wang)安全穩定(ding)運行，加大重點領域科(ke)技(ji)(ji)投(tou)入(ru)，攻克關(guan)鍵技(ji)(ji)術(shu)(shu)難(nan)題，為建(jian)設(she)運行750千(qian)伏主(zhu)網(wang)(wang)架提供支撐。2008年(nian)，9項(xiang)(xiang)科(ke)技(ji)(ji)成果獲(huo)國(guo)家電(dian)(dian)(dian)(dian)網(wang)(wang)公司、陜西(xi)(xi)省科(ke)技(ji)(ji)進(jin)步獎項(xiang)(xiang)，獲(huo)獎數(shu)量為歷年(nian)之最；專(zhuan)利申報實現歷史性突破(po)，獲(huo)得國(guo)家專(zhuan)利授(shou)權(quan)26項(xiang)(xiang)。成立西(xi)(xi)北(bei)風(feng)電(dian)(dian)(dian)(dian)研究(jiu)中(zhong)心，舉辦全國(guo)性風(feng)電(dian)(dian)(dian)(dian)技(ji)(ji)術(shu)(shu)論壇，開展調度測(ce)風(feng)網(wang)(wang)絡(luo)規(gui)劃研究(jiu)，在(zai)甘(gan)肅(su)酒泉建(jian)成投(tou)運了3基(ji)用于電(dian)(dian)(dian)(dian)網(wang)(wang)調度的示范(fan)測(ce)風(feng)塔，電(dian)(dian)(dian)(dian)網(wang)(wang)調度測(ce)風(feng)網(wang)(wang)絡(luo)進(jin)入(ru)實際應用階(jie)段，為推動西(xi)(xi)北(bei)風(feng)電(dian)(dian)(dian)(dian)規(gui)模發(fa)展奠定(ding)了基(ji)礎。
