國家電網公司認真貫徹黨中央、國務院關于調整振興裝備制造業的決策部署，在電網建設工程中努力提高設備國產化率，進一步帶動國產電工設備技術和制造水平提升。近日，作為國家發改委核準的“首臺套依托示范工程”寧東—山東±660千伏直流輸電示范工程在京簽訂主設備采購合同。
寧東—山東±660千(qian)伏直流輸(shu)電(dian)(dian)(dian)示范工(gong)程是世界(jie)上(shang)首個(ge)±660千(qian)伏電(dian)(dian)(dian)壓等(deng)級(ji)直流輸(shu)電(dian)(dian)(dian)工(gong)程，總(zong)(zong)(zong)投資(zi)104億(yi)元，線路長度1335千(qian)米, 計劃于2010年底單級(ji)建成投運，2011年雙極建成投運。本(ben)次設備(bei)采購范圍(wei)包括換流變壓器(qi)(qi)、平(ping)波電(dian)(dian)(dian)抗器(qi)(qi)、換流閥、直流控(kong)制保護等(deng)直流輸(shu)電(dian)(dian)(dian)關鍵設備(bei)，主要由(you)中國(guo)(guo)西電(dian)(dian)(dian)電(dian)(dian)(dian)氣(qi)股份有限(xian)公司、特變電(dian)(dian)(dian)工(gong)沈(shen)陽變壓器(qi)(qi)集(ji)團有限(xian)公司、新疆(jiang)特變電(dian)(dian)(dian)工(gong)股份有限(xian)公司、北京電(dian)(dian)(dian)力(li)設備(bei)總(zong)(zong)(zong)廠(chang)(chang)、中國(guo)(guo)電(dian)(dian)(dian)力(li)科學研(yan)究院、許繼集(ji)團有限(xian)公司等(deng)國(guo)(guo)內(nei)電(dian)(dian)(dian)工(gong)設備(bei)制造廠(chang)(chang)商制造，合同總(zong)(zong)(zong)額達15.8690億(yi)元，對于拉(la)動(dong)內(nei)需，帶動(dong)我國(guo)(guo)電(dian)(dian)(dian)工(gong)制造行業(ye)技術升級(ji)和(he)自(zi)主創新，推(tui)動(dong)直流輸(shu)電(dian)(dian)(dian)技術發(fa)展具有重(zhong)要意義(yi)。工(gong)程的建設將對發(fa)揮西部(bu)地區煤電(dian)(dian)(dian)資(zi)源優(you)勢和(he)東部(bu)沿海經(jing)濟優(you)勢，實現節能減排，推(tui)動(dong)社會和(he)諧(xie)具有重(zhong)要社會經(jing)濟意義(yi)。
