截(jie)至目前，根據國(guo)家能源局(ju)去年9月印(yin)發(fa)(fa)的(de)《關于加快推(tui)進一批輸(shu)變電重點工(gong)程規劃建設(she)工(gong)作的(de)通知(zhi)》（以(yi)下簡(jian)稱“《通知(zhi)》”），已有青海-河(he)(he)南(nan)、陜北(bei)-湖北(bei)、雅中-江西特高(gao)壓直流(liu)工(gong)程和張北(bei)-雄安、駐(zhu)馬店-南(nan)陽特高(gao)壓交流(liu)工(gong)程，以(yi)及云貴(gui)互聯工(gong)程相繼(ji)獲得國(guo)家發(fa)(fa)改委(wei)、河(he)(he)北(bei)省發(fa)(fa)改委(wei)、河(he)(he)南(nan)省發(fa)(fa)改委(wei)等(deng)政(zheng)府部門核準(zhun)。記(ji)者注意到，特高(gao)壓核準(zhun)速度低于《通知(zhi)》要求。

多項工程未按要求核準

業(ye)界普(pu)遍認為，去年(nian)9月《通(tong)知(zhi)》發布，標志著特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)將(jiang)迎來(lai)新(xin)一輪(lun)建(jian)設高(gao)(gao)(gao)峰(feng)。根據《通(tong)知(zhi)》，為配套青海(hai)-河南(nan)特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)直流(liu)(liu)工(gong)(gong)(gong)程(cheng)，將(jiang)建(jian)設駐(zhu)馬(ma)店-南(nan)陽、駐(zhu)馬(ma)店-武(wu)漢(han)(han)(han)特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)流(liu)(liu)工(gong)(gong)(gong)程(cheng)；陜北-湖北特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)直流(liu)(liu)工(gong)(gong)(gong)程(cheng)落點武(wu)漢(han)(han)(han)，將(jiang)配套建(jian)設荊門-武(wu)漢(han)(han)(han)特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)流(liu)(liu)工(gong)(gong)(gong)程(cheng)；雅中-江西特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)直流(liu)(liu)工(gong)(gong)(gong)程(cheng)落點南(nan)昌，將(jiang)配套建(jian)設南(nan)昌-武(wu)漢(han)(han)(han)、南(nan)昌-長沙(sha)特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)流(liu)(liu)工(gong)(gong)(gong)程(cheng)。同時，《通(tong)知(zhi)》還要求推(tui)進白鶴灘-江蘇、白鶴灘-浙江特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)直流(liu)(liu)工(gong)(gong)(gong)程(cheng)和張北-雄安、南(nan)陽-荊門-長沙(sha)特(te)高(gao)(gao)(gao)壓(ya)(ya)(ya)(ya)交(jiao)流(liu)(liu)工(gong)(gong)(gong)程(cheng)，以(yi)及云(yun)貴互聯通(tong)道工(gong)(gong)(gong)程(cheng)、閩粵聯網工(gong)(gong)(gong)程(cheng)。

《通知(zhi)》要求，2018年第四季度要核準青(qing)海-河南(nan)、陜北(bei)-湖北(bei)、雅中(zhong)-江(jiang)西特(te)高壓直流及張北(bei)-雄安特(te)高壓交流工(gong)程，白鶴(he)灘-江(jiang)蘇、白鶴(he)灘-浙江(jiang)、南(nan)陽-荊門(men)-長(chang)沙特(te)高壓交流、云貴互聯通道、閩(min)粵聯網工(gong)程要求在2019年核準。

而實際上，2018年(nian)10月，國(guo)家發改(gai)委(wei)核(he)準(zhun)了(le)青(qing)海-河(he)南(nan)(nan)特(te)高壓直(zhi)流(liu)(liu)工(gong)(gong)(gong)(gong)程(cheng)；2018年(nian)11月，河(he)北省(sheng)發改(gai)委(wei)核(he)準(zhun)張(zhang)北-雄安特(te)高壓交流(liu)(liu)工(gong)(gong)(gong)(gong)程(cheng)；2018年(nian)11月，河(he)南(nan)(nan)省(sheng)發改(gai)委(wei)核(he)準(zhun)駐馬店-南(nan)(nan)陽特(te)高壓交流(liu)(liu)工(gong)(gong)(gong)(gong)程(cheng)，作為青(qing)海-河(he)南(nan)(nan)特(te)高壓直(zhi)流(liu)(liu)的配(pei)套工(gong)(gong)(gong)(gong)程(cheng)；2019年(nian)1月，國(guo)家發改(gai)委(wei)核(he)準(zhun)陜北-湖(hu)北特(te)高壓直(zhi)流(liu)(liu)工(gong)(gong)(gong)(gong)程(cheng)；2019年(nian)8月，國(guo)家發改(gai)委(wei)核(he)準(zhun)雅中-江西特(te)高壓直(zhi)流(liu)(liu)工(gong)(gong)(gong)(gong)程(cheng)。此外(wai)，今年(nian)7月，云貴互聯(lian)通道工(gong)(gong)(gong)(gong)程(cheng)獲(huo)國(guo)家發改(gai)委(wei)核(he)準(zhun)。

其中，云貴互聯通道工(gong)(gong)程(cheng)是國內首個將(jiang)兩端(duan)常(chang)規直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)改造(zao)為三端(duan)常(chang)規直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)的(de)工(gong)(gong)程(cheng)，也(ye)是昆柳龍直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)工(gong)(gong)程(cheng)（烏東(dong)德電站送(song)電廣(guang)東(dong)廣(guang)西特(te)高(gao)壓多端(duan)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)示(shi)范(fan)工(gong)(gong)程(cheng)）之(zhi)后南方電網公(gong)司建設的(de)第(di)二個多端(duan)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)工(gong)(gong)程(cheng)，將(jiang)形成云南祿勸換(huan)流(liu)(liu)(liu)(liu)站-貴州高(gao)坡換(huan)流(liu)(liu)(liu)(liu)站-廣(guang)東(dong)肇慶換(huan)流(liu)(liu)(liu)(liu)站三端(duan)直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)。

距離(li)2019年(nian)底還(huan)有不到兩個月(yue)時間，白(bai)鶴灘-江(jiang)蘇、白(bai)鶴灘-浙江(jiang)特高壓直流和(he)南陽-荊門-長沙特高壓交流工(gong)程、閩粵聯網工(gong)程及部分配(pei)套(tao)工(gong)程還(huan)未按(an)《通知》要(yao)求核(he)準。

剩余特高壓正開展前期工作

10月11日召(zhao)開(kai)的國家能源(yuan)(yuan)委員會會議要(yao)求，加快輸(shu)煤輸(shu)電(dian)(dian)大通道建設，發展水(shui)電(dian)(dian)、風(feng)電(dian)(dian)、光電(dian)(dian)等可再生能源(yuan)(yuan)，提高清潔能源(yuan)(yuan)消納(na)水(shui)平，聚焦短板，推進能源(yuan)(yuan)重大工(gong)程建設，這意(yi)味著剩余輸(shu)變電(dian)(dian)重點(dian)工(gong)程核準有望提速。

據了解(jie)，國家電網公(gong)司(si)此前已發布《駐馬(ma)店-武漢1000千伏特高(gao)壓(ya)(ya)交(jiao)流(liu)輸變電工(gong)(gong)(gong)程環(huan)境影(ying)響報告書（報批稿）》，標志(zhi)著該工(gong)(gong)(gong)程將進入核準(zhun)(zhun)開工(gong)(gong)(gong)階段；閩粵聯(lian)網工(gong)(gong)(gong)程已完成(cheng)可研等工(gong)(gong)(gong)作(zuo)，具備核準(zhun)(zhun)條件。此外，近日有消息稱，南陽-荊門-長沙(sha)特高(gao)壓(ya)(ya)交(jiao)流(liu)工(gong)(gong)(gong)程、白鶴灘-江(jiang)蘇特高(gao)壓(ya)(ya)直流(liu)工(gong)(gong)(gong)程有望(wang)在年內獲(huo)核準(zhun)(zhun)。

其中，閩粵聯(lian)網(wang)工程將使我國東(dong)(dong)南(nan)沿海福(fu)建、廣(guang)東(dong)(dong)兩個經濟(ji)發達(da)省份的(de)電(dian)網(wang)實現聯(lian)網(wang)，保障地區的(de)供電(dian)安(an)全性，為推動全國電(dian)力市場(chang)建設構筑(zhu)重(zhong)要的(de)網(wang)架基(ji)礎。據悉，該工程由國網(wang)和南(nan)網(wang)共同(tong)投(tou)資，擬采用直(zhi)流(liu)背(bei)靠(kao)背(bei)聯(lian)網(wang)方式建設，對加(jia)強國網(wang)和南(nan)網(wang)互(hu)(hu)聯(lian)互(hu)(hu)通(tong)、余缺互(hu)(hu)濟(ji)和緊急事(shi)故支援能力等具有重(zhong)要意義(yi)。此(ci)前，國網(wang)和南(nan)網(wang)僅(jin)通(tong)過三(san)峽-廣(guang)東(dong)(dong)單回500千伏直(zhi)流(liu)線路異步互(hu)(hu)聯(lian)。

華北特高壓交流網架呼之欲出

記者(zhe)近日從國家(jia)電(dian)網公(gong)司(si)獲悉，山東(dong)(dong)-河北(bei)(bei)特(te)(te)高(gao)(gao)(gao)壓(ya)(ya)交(jiao)流(liu)環網工(gong)程(cheng)(cheng)將(jiang)(jiang)于12月全線架通。“建(jian)設山東(dong)(dong)-河北(bei)(bei)特(te)(te)高(gao)(gao)(gao)壓(ya)(ya)環網工(gong)程(cheng)(cheng)，將(jiang)(jiang)支撐扎魯(lu)(lu)特(te)(te)-青(qing)州、上海廟-臨沂等(deng)特(te)(te)高(gao)(gao)(gao)壓(ya)(ya)直流(liu)工(gong)程(cheng)(cheng)穩定運行，提高(gao)(gao)(gao)京津冀(ji)魯(lu)(lu)特(te)(te)別是山東(dong)(dong)電(dian)網接(jie)納(na)區外電(dian)力的能力和內部(bu)電(dian)力交(jiao)換(huan)能力。”該公(gong)司(si)相關人士介紹，該工(gong)程(cheng)(cheng)將(jiang)(jiang)與蒙(meng)西-天(tian)津南、榆橫(heng)-濰坊（“兩(liang)橫(heng)”）及蒙(meng)西-晉中-晉東(dong)(dong)南、北(bei)(bei)京西-石家(jia)莊(zhuang)、錫盟-山東(dong)(dong)（“三縱”）特(te)(te)高(gao)(gao)(gao)壓(ya)(ya)交(jiao)流(liu)工(gong)程(cheng)(cheng)共同構(gou)建(jian)華北(bei)(bei)“兩(liang)橫(heng)三縱一環網”特(te)(te)高(gao)(gao)(gao)壓(ya)(ya)交(jiao)流(liu)受(shou)端網架，形成我國第(di)二個特(te)(te)高(gao)(gao)(gao)壓(ya)(ya)交(jiao)流(liu)環網。

9月26日，蘇(su)(su)通(tong)1000千伏交流(liu)特(te)高壓(ya)GIL（氣體絕緣金(jin)屬封閉輸電線(xian)路）綜(zong)合(he)管(guan)廊(lang)(lang)工程(cheng)(cheng)(cheng)(cheng)投運(yun)，標志著(zhu)華東(dong)特(te)高壓(ya)交流(liu)環(huan)(huan)網(wang)真正實現了合(he)環(huan)(huan)運(yun)行。據了解，該環(huan)(huan)網(wang)是(shi)世界上(shang)首(shou)個(ge)特(te)高壓(ya)交流(liu)環(huan)(huan)網(wang)，主要由淮南(nan)-浙北(bei)-上(shang)海(hai)特(te)高壓(ya)交流(liu)工程(cheng)(cheng)(cheng)(cheng)，即皖電東(dong)送(song)（“南(nan)半環(huan)(huan)”）和淮南(nan)-南(nan)京-上(shang)海(hai)特(te)高壓(ya)交流(liu)工程(cheng)(cheng)(cheng)(cheng)（“北(bei)半環(huan)(huan)”）組成，蘇(su)(su)通(tong)GIL綜(zong)合(he)管(guan)廊(lang)(lang)工程(cheng)(cheng)(cheng)(cheng)是(shi)華東(dong)特(te)高壓(ya)交流(liu)環(huan)(huan)網(wang)合(he)環(huan)(huan)運(yun)行的咽喉要道和控(kong)制性工程(cheng)(cheng)(cheng)(cheng)。

另據悉，目前駐(zhu)馬(ma)店-南(nan)(nan)(nan)陽特(te)高壓(ya)交流(liu)(liu)(liu)工(gong)程已全面進(jin)入架線(xian)施工(gong)階段，該工(gong)程將與(yu)《通知(zhi)》要(yao)求的(de)(de)駐(zhu)馬(ma)店-武(wu)(wu)漢(han)(han)、荊(jing)門-武(wu)(wu)漢(han)(han)、南(nan)(nan)(nan)昌(chang)-武(wu)(wu)漢(han)(han)、南(nan)(nan)(nan)昌(chang)-長(chang)沙、南(nan)(nan)(nan)陽-荊(jing)門-長(chang)沙特(te)高壓(ya)交流(liu)(liu)(liu)工(gong)程，以及在(zai)運的(de)(de)晉東(dong)南(nan)(nan)(nan)-南(nan)(nan)(nan)陽-荊(jing)門特(te)高壓(ya)交流(liu)(liu)(liu)工(gong)程形成(cheng)(cheng)覆蓋南(nan)(nan)(nan)陽、駐(zhu)馬(ma)店、武(wu)(wu)漢(han)(han)、荊(jing)門、南(nan)(nan)(nan)昌(chang)、長(chang)沙的(de)(de)“日(ri)”字形華中特(te)高壓(ya)交流(liu)(liu)(liu)網(wang)架，形成(cheng)(cheng)我國第三(san)個特(te)高壓(ya)交流(liu)(liu)(liu)環(huan)網(wang)。
