:6月(yue)10日(ri)，記者從國(guo)網(wang)青(qing)海省電(dian)力公(gong)司(si)獲悉(xi)，6月(yue)8日(ri)14時23分，750千(qian)伏寧塔I回π接工(gong)程(cheng)圓(yuan)滿完(wan)成(cheng)，標志著750千(qian)伏電(dian)源(yuan)(yuan)順(shun)利接入青(qing)南(nan)換(huan)流站(zhan)(zhan)，將給青(qing)南(nan)換(huan)流站(zhan)(zhan)提(ti)供(gong)穩定的電(dian)源(yuan)(yuan)支撐，為青(qing)海-河南(nan)±800千(qian)伏特高壓工(gong)程(cheng)清潔能(neng)源(yuan)(yuan)外送奠(dian)定了堅實的基礎。

此(ci)次(ci)750千伏寧(ning)塔I回π接施工是(shi)±800千伏青(qing)(qing)(qing)南(nan)換(huan)(huan)流站(zhan)的(de)“電源(yuan)接入工程”，通(tong)過“π接”施工方式將原(yuan)有的(de)寧(ning)塔I線(xian)打(da)開后形成新的(de)塔拉(la)-青(qing)(qing)(qing)南(nan)I回750千伏線(xian)路和(he)西寧(ning)-青(qing)(qing)(qing)南(nan)III回750千伏線(xian)路，然后將電源(yuan)送往(wang)青(qing)(qing)(qing)豫特高壓的(de)心臟(zang)——青(qing)(qing)(qing)南(nan)換(huan)(huan)流站(zhan)，通(tong)過換(huan)(huan)流后將源(yuan)源(yuan)不斷的(de)清潔(jie)能源(yuan)送往(wang)河南(nan)。

“也就是(shi)說(shuo)(shuo)只有通(tong)過‘π接’施(shi)工(gong)(gong)，才能打通(tong)整個青(qing)(qing)(qing)豫特(te)高(gao)壓工(gong)(gong)程的‘任督(du)二脈(mo)’，實現(xian)青(qing)(qing)(qing)南換流站“6.30”雙極低端帶(dai)電投運的既定目標”青(qing)(qing)(qing)海(hai)送變(bian)電工(gong)(gong)程有限公司現(xian)場施(shi)工(gong)(gong)負責(ze)人(ren)曾生偉介(jie)紹說(shuo)(shuo)，此(ci)次“π”接施(shi)工(gong)(gong)的完成(cheng)將(jiang)為青(qing)(qing)(qing)豫特(te)高(gao)壓提(ti)供重要的電源(yuan)保(bao)障(zhang)，為青(qing)(qing)(qing)海(hai)清潔能源(yuan)外送“加速度”。

“青豫”特高(gao)壓是世界(jie)首條(tiao)專為(wei)清(qing)潔能源(yuan)(yuan)外(wai)送而建(jian)設的(de)特高(gao)壓通道，工(gong)(gong)(gong)程的(de)建(jian)設將有(you)效提升青海大部分地(di)區(qu)清(qing)潔能源(yuan)(yuan)的(de)整體外(wai)送消納水平(ping)，對緩解河南(nan)地(di)區(qu)供電(dian)緊張局面(mian)、保障河南(nan)不斷(duan)增長的(de)電(dian)力需求、促進大氣污(wu)染防治和能源(yuan)(yuan)業轉型發展將發揮重要作用。為(wei)了(le)確保這(zhe)項工(gong)(gong)(gong)程順利建(jian)設，早日發揮社會經濟效益(yi)，國(guo)家電(dian)網有(you)限(xian)公司倒(dao)排工(gong)(gong)(gong)期，克服重重困難，加快推(tui)進工(gong)(gong)(gong)程建(jian)設。

負責工(gong)(gong)程(cheng)施(shi)工(gong)(gong)的青海送變電工(gong)(gong)程(cheng)有(you)限公司制(zhi)定了專項施(shi)工(gong)(gong)方案，針對鐵塔拆除施(shi)工(gong)(gong)中(zhong)的難點，多次測算拉(la)線(xian)拉(la)力與角(jiao)度，并在軟件中(zhong)多次模擬演(yan)算，制(zhi)作施(shi)工(gong)(gong)動態動畫，輔助安全施(shi)工(gong)(gong)。

對吊車組立鐵塔(ta)(ta)、拆塔(ta)(ta)作業、高空導地線斷線、壓接(jie)(jie)等作業工(gong)序(xu)進(jin)行雙(shuang)保險(xian)二次臨錨保護，將跨越(yue)架(jia)、地錨、拉(la)線檢查列為重要執行監護點。施工(gong)現(xian)場(chang)落(luo)實管理人員到(dao)崗到(dao)位、風險(xian)管控措(cuo)施，確保責任(ren)到(dao)人，不斷加強施工(gong)現(xian)場(chang)安全、質量(liang)(liang)、進(jin)度(du)管控力量(liang)(liang)，確保了此次“π”接(jie)(jie)工(gong)程按(an)期完成(cheng)。

據(ju)悉，“青豫”特(te)高(gao)壓工程(cheng)投運后每年可(ke)向(xiang)河南輸送(song)(song)清潔電力400億千瓦時，將有力推動青海(hai)千萬千瓦級新能源(yuan)基(ji)地集約化開發(fa)建設和大規模外(wai)送(song)(song)，提高(gao)西北地區可(ke)再生能源(yuan)整體外(wai)送(song)(song)消納水(shui)平。
