四(si)(si)川省(sheng)政府(fu)日前(qian)印發的《四(si)(si)川省(sheng)“十四(si)(si)五”能(neng)源發展(zhan)規劃(hua)(hua)》（以下簡稱《規劃(hua)(hua)》）提出(chu)，“十四(si)(si)五”將建(jian)成(cheng)雅礱江(jiang)中游-江(jiang)西、白(bai)鶴灘(tan)-江(jiang)蘇、白(bai)鶴灘(tan)-浙江(jiang)等±800千(qian)伏(fu)特(te)高(gao)壓(ya)直流工(gong)程，開工(gong)建(jian)設金沙江(jiang)上(shang)游-湖北(bei)多能(neng)互補外送特(te)高(gao)壓(ya)直流工(gong)程。

      據了解，除(chu)了確(que)定開工建設的特高(gao)壓(ya)工程(cheng)外(wai)，多個(ge)特高(gao)壓(ya)工程(cheng)研究論證(zheng)工作(zuo)也已同步啟(qi)動。國家能源局剛剛啟(qi)動西(xi)北(bei)區(qu)域“3交9直”等跨省跨區(qu)輸電(dian)(dian)通道(dao)和配套電(dian)(dian)源一體化方(fang)案研究論證(zheng)工作(zuo)；《規劃》提出，研究規劃與西(xi)北(bei)電(dian)(dian)網(wang)聯接第二(er)通道(dao)，研究布局藏(zang)東(dong)南和雅(ya)魯藏(zang)布江下游水電(dian)(dian)入(ru)川接續(xu)轉送特高(gao)壓(ya)工程(cheng)。重(zhong)點(dian)推進(jin)川渝電(dian)(dian)網(wang)特高(gao)壓(ya)交流目(mu)標網(wang)架建設，為成渝地區(qu)雙城經濟圈建設提供堅強電(dian)(dian)力保障。

    記者從知(zhi)情人士(shi)處獨家獲(huo)悉(xi)，“十四五”期間，國(guo)網經營區特(te)高(gao)(gao)壓直流項目(mu)投資將翻番；“十五五”期間，國(guo)家會(hui)繼續加大特(te)高(gao)(gao)壓項目(mu)投資。

今年開工項目集中在四川

     與四(si)川(chuan)(chuan)毗鄰的西(xi)藏(zang)及(ji)西(xi)北各省區(qu)的清(qing)潔能源(yuan)資(zi)(zi)源(yuan)極其豐富，是保障四(si)川(chuan)(chuan)電(dian)(dian)(dian)力(li)(li)供(gong)應的重要電(dian)(dian)(dian)力(li)(li)來(lai)源(yuan)。西(xi)藏(zang)水電(dian)(dian)(dian)資(zi)(zi)源(yuan)量(liang)居全國(guo)(guo)第一，光伏開發潛力(li)(li)巨(ju)大(da)(da)，而本地負(fu)荷體量(liang)小(xiao)、主(zhu)要靠外送(song)(song)(song)消納。四(si)川(chuan)(chuan)位于西(xi)藏(zang)外送(song)(song)(song)電(dian)(dian)(dian)的必經之路，隨著本省電(dian)(dian)(dian)力(li)(li)需求(qiu)的持續增(zeng)加(jia)，已建(jian)和將要建(jian)設的多回特高壓(ya)直流通(tong)道(dao)(dao)可(ke)(ke)通(tong)過新建(jian)西(xi)藏(zang)-四(si)川(chuan)(chuan)電(dian)(dian)(dian)力(li)(li)通(tong)道(dao)(dao)引入西(xi)藏(zang)電(dian)(dian)(dian)源(yuan)接(jie)續送(song)(song)(song)電(dian)(dian)(dian)。“一方面，可(ke)(ke)保持‘西(xi)電(dian)(dian)(dian)東送(song)(song)(song)’大(da)(da)通(tong)道(dao)(dao)持續輸(shu)送(song)(song)(song)清(qing)潔電(dian)(dian)(dian)力(li)(li)，保證(zheng)中(zhong)東部地區(qu)電(dian)(dian)(dian)力(li)(li)供(gong)應；另一方面，也可(ke)(ke)提高省內(nei)電(dian)(dian)(dian)源(yuan)支撐用電(dian)(dian)(dian)需求(qiu)的力(li)(li)度，基本滿(man)足‘十五(wu)五(wu)’時期負(fu)荷中(zhong)心電(dian)(dian)(dian)力(li)(li)增(zeng)長需求(qiu)，促進成渝地區(qu)雙城經濟圈等國(guo)(guo)家戰略落地。”國(guo)(guo)網(wang)四(si)川(chuan)(chuan)電(dian)(dian)(dian)力(li)(li)相關負(fu)責(ze)人接(jie)受記者采訪時表示(shi)。

     談及《規(gui)(gui)劃》中的西(xi)北至(zhi)四(si)(si)川(chuan)電(dian)(dian)力(li)(li)(li)通道規(gui)(gui)劃論證(zheng)工作(zuo)，國網(wang)(wang)四(si)(si)川(chuan)電(dian)(dian)力(li)(li)(li)相(xiang)關負責人表示，規(gui)(gui)劃建設西(xi)北-四(si)(si)川(chuan)第(di)二(er)通道，除可保(bao)障四(si)(si)川(chuan)電(dian)(dian)力(li)(li)(li)供(gong)應、促進(jin)清(qing)潔低碳轉型外，豐(feng)水(shui)(shui)期可將(jiang)四(si)(si)川(chuan)清(qing)潔電(dian)(dian)力(li)(li)(li)送至(zhi)西(xi)北地(di)區，更(geng)能(neng)提升(sheng)運行靈活性(xing)和安全水(shui)(shui)平，進(jin)一步擴大四(si)(si)川(chuan)和西(xi)北“水(shui)(shui)火風(feng)光互(hu)濟”規(gui)(gui)模，增強日內(nei)西(xi)北光伏白(bai)天大發或四(si)(si)川(chuan)水(shui)(shui)電(dian)(dian)夜間低谷時段(duan)的消納范圍和能(neng)力(li)(li)(li)，增強電(dian)(dian)網(wang)(wang)調節(jie)性(xing)能(neng)和運行靈活性(xing)。

    “特(te)高(gao)(gao)壓建(jian)設的(de)(de)重點一直是(shi)直流項目(mu)，交流特(te)高(gao)(gao)壓只是(shi)補充。”上(shang)述知情人士接受記者采訪時透露，“目(mu)前，在建(jian)的(de)(de)項目(mu)正按計劃推(tui)進，今年特(te)高(gao)(gao)壓建(jian)設的(de)(de)重點在四川，開工的(de)(de)幾個大項目(mu)基本(ben)上(shang)都在那邊。”

       記者從國網四川電(dian)力了解(jie)到，雅中-江(jiang)西工(gong)程已(yi)于2021年(nian)(nian)(nian)(nian)6月(yue)(yue)啟(qi)動投運。白鶴灘-江(jiang)蘇(su)工(gong)程計劃(hua)今年(nian)(nian)(nian)(nian)6月(yue)(yue)低(di)端(duan)(duan)投運，12月(yue)(yue)高(gao)端(duan)(duan)投運。白鶴灘-江(jiang)蘇(su)工(gong)程已(yi)基本(ben)全線貫通，正開展(zhan)消缺驗收工(gong)作。去年(nian)(nian)(nian)(nian)7月(yue)(yue)核準(zhun)的白鶴灘-浙江(jiang)工(gong)程目前已(yi)進入組塔(ta)轉(zhuan)序階段(duan)，計劃(hua)今年(nian)(nian)(nian)(nian)12月(yue)(yue)雙(shuang)極低(di)端(duan)(duan)投運，2023年(nian)(nian)(nian)(nian)6月(yue)(yue)雙(shuang)極高(gao)端(duan)(duan)投運。“因金(jin)沙江(jiang)上(shang)游到湖北(bei)特高(gao)壓直流工(gong)程尚未核準(zhun)，所(suo)以目前暫無開工(gong)建(jian)設時間表。”上(shang)述(shu)相關負責人(ren)向記者透露。
