6月4日，國內最高落差抽水蓄能(neng)電站(zhan)——吉林敦(dun)化抽水蓄能(neng)電站(zhan)1號機組(zu)投產發(fa)電，較原計(ji)劃提前26天。

吉(ji)林(lin)敦化抽(chou)水(shui)(shui)(shui)(shui)(shui)(shui)蓄能(neng)電(dian)(dian)站(zhan)位于吉(ji)林(lin)省敦化市北(bei)部，最(zui)高揚程達到712米，是國內首座700米級水(shui)(shui)(shui)(shui)(shui)(shui)位高差抽(chou)水(shui)(shui)(shui)(shui)(shui)(shui)蓄能(neng)電(dian)(dian)站(zhan)。該(gai)電(dian)(dian)站(zhan)安裝4臺單機容(rong)(rong)量35萬(wan)千(qian)瓦(wa)可(ke)逆(ni)式(shi)水(shui)(shui)(shui)(shui)(shui)(shui)泵水(shui)(shui)(shui)(shui)(shui)(shui)輪(lun)發(fa)(fa)電(dian)(dian)電(dian)(dian)動機組，總裝機容(rong)(rong)量140萬(wan)千(qian)瓦(wa)，年設計發(fa)(fa)電(dian)(dian)量為23.42億(yi)(yi)千(qian)瓦(wa)時，抽(chou)水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)(dian)量31.23億(yi)(yi)千(qian)瓦(wa)時，以500千(qian)伏出(chu)線接入吉(ji)林(lin)電(dian)(dian)網。中國電(dian)(dian)建(jian)(jian)(jian)所屬北(bei)京院設計，水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)(dian)六局、水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)(dian)十一局、水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)(dian)十四局、水(shui)(shui)(shui)(shui)(shui)(shui)電(dian)(dian)十六局、電(dian)(dian)建(jian)(jian)(jian)建(jian)(jian)(jian)筑公司承(cheng)建(jian)(jian)(jian)了(le)上下(xia)水(shui)(shui)(shui)(shui)(shui)(shui)庫大(da)壩、引水(shui)(shui)(shui)(shui)(shui)(shui)系統(tong)(tong)、通風(feng)兼出(chu)線洞(dong)(dong)、交(jiao)通洞(dong)(dong)、自流排水(shui)(shui)(shui)(shui)(shui)(shui)洞(dong)(dong)、地(di)下(xia)廠房(fang)及尾(wei)水(shui)(shui)(shui)(shui)(shui)(shui)系統(tong)(tong)、機電(dian)(dian)安裝等工(gong)程。

敦化電(dian)站的建設(she)及投產，創造了國內抽(chou)水(shui)蓄(xu)能電(dian)站工(gong)程(cheng)建設(she)的多(duo)項(xiang)紀錄。其中，大壩(ba)主(zhu)體工(gong)程(cheng)在施工(gong)建設(she)中，嚴(yan)控原材料質量(liang)關，優選(xuan)骨料級配，精心開展配合比(bi)試驗，嚴(yan)格控制瀝青混(hun)凝(ning)土(tu)(tu)溫度和密實度，成功(gong)建設(she)了嚴(yan)寒地區抽(chou)水(shui)蓄(xu)能電(dian)站首個瀝青混(hun)凝(ning)土(tu)(tu)心墻堆石壩(ba)，大壩(ba)建設(she)質量(liang)優秀，下(xia)水(shui)庫(ku)蓄(xu)水(shui)后大壩(ba)滲漏量(liang)僅為7升每(mei)秒。

據悉，吉林敦化抽(chou)水(shui)蓄(xu)能(neng)電(dian)站是吉林省“十二(er)五”規劃建(jian)設的重點項目(mu)(mu)，是目(mu)(mu)前東(dong)北地區最大(da)、吉林省首(shou)座純抽(chou)水(shui)蓄(xu)能(neng)電(dian)站，也(ye)是延邊州投資(zi)最大(da)的單體工(gong)程(cheng)。該電(dian)站建(jian)成后，將有效(xiao)緩解(jie)東(dong)北地區電(dian)網調節能(neng)力不足問題，充分(fen)發(fa)揮電(dian)力供應(ying)和調峰填(tian)谷作用(yong)，為東(dong)北電(dian)網安全穩定(ding)運行和促進新能(neng)源(yuan)消納提(ti)供了更加堅強的保障。
