近(jin)日，國家(jia)電網(wang)(wang)公(gong)司為深化(hua)基建標準化(hua)建設，進一步(bu)提(ti)高西北電網(wang)(wang)750千伏(fu)輸(shu)變電工程(cheng)建設效率和效益(yi)，決定在已有(you)的750千伏(fu)變電站通(tong)(tong)用設計(ji)基礎上(shang)，全面(mian)開展750千伏(fu)輸(shu)變電工程(cheng)“三通(tong)(tong)一標”（通(tong)(tong)用設計(ji)、通(tong)(tong)用設備、通(tong)(tong)用造價和標準工藝(yi)）工作。
據西北電網(wang)有(you)限公司(si)相關部(bu)門人員介紹，這項工(gong)作(zuo)以500千伏及(ji)以下輸變(bian)電工(gong)程(cheng)“三通一標”工(gong)作(zuo)成(cheng)果為(wei)基(ji)礎，按照“兩型一化”要求，貫(guan)徹(che)全壽(shou)命周期(qi)費用最優原則，總結、提煉已有(you)750千伏輸變(bian)電工(gong)程(cheng)設(she)(she)計建設(she)(she)經驗和(he)成(cheng)果，集成(cheng)應用成(cheng)熟適用新技術(shu)，形成(cheng)750千伏輸變(bian)電工(gong)程(cheng)的“三通一標”，用以指導工(gong)程(cheng)設(she)(she)計、評審和(he)建設(she)(she)。
750千(qian)伏(fu)輸(shu)變電(dian)(dian)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)“三(san)通一(yi)標”是國(guo)家(jia)電(dian)(dian)網(wang)公司(si)基建(jian)標準(zhun)化建(jian)設成果的有(you)機(ji)組(zu)成部分，能夠發(fa)揮規(gui)模(mo)優勢(shi)，提(ti)高國(guo)家(jia)電(dian)(dian)網(wang)公司(si)整體(ti)效益，有(you)利(li)(li)于統(tong)一(yi)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)設計標準(zhun)，提(ti)高設計質量(liang)，提(ti)高工(gong)(gong)(gong)(gong)(gong)作(zuo)效率；有(you)利(li)(li)于統(tong)一(yi)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)建(jian)設標準(zhun)和設備(bei)規(gui)范，方便運行(xing)(xing)維護，提(ti)高電(dian)(dian)網(wang)安全穩定運行(xing)(xing)水平(ping)(ping)，降(jiang)低工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)全壽命(ming)周期總(zong)體(ti)費用。科學建(jian)立750千(qian)伏(fu)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)造價標準(zhun)，合理評價工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)技(ji)術經濟指標水平(ping)(ping)，可有(you)效控制電(dian)(dian)網(wang)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)投(tou)資，降(jiang)低建(jian)設和運行(xing)(xing)成本，同時(shi)為項目可行(xing)(xing)性(xing)研究(jiu)、工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)初步(bu)設計、集中規(gui)模(mo)招標和工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)竣工(gong)(gong)(gong)(gong)(gong)決算(suan)等工(gong)(gong)(gong)(gong)(gong)作(zuo)的開展(zhan)提(ti)供依據。
