6月(yue)4日，國內(nei)最高落差(cha)抽(chou)水(shui)(shui)蓄能電(dian)站——吉林敦(dun)化抽(chou)水(shui)(shui)蓄能電(dian)站1號機組投產發電(dian)，較原計劃提前26天。

吉(ji)林(lin)(lin)敦化(hua)抽(chou)(chou)水(shui)(shui)(shui)(shui)蓄能(neng)電(dian)(dian)站位于吉(ji)林(lin)(lin)省敦化(hua)市(shi)北(bei)部，最高揚(yang)程達(da)到(dao)712米，是國內(nei)首(shou)座700米級水(shui)(shui)(shui)(shui)位高差抽(chou)(chou)水(shui)(shui)(shui)(shui)蓄能(neng)電(dian)(dian)站。該電(dian)(dian)站安裝4臺單機(ji)(ji)容量35萬千(qian)瓦(wa)(wa)可(ke)逆式水(shui)(shui)(shui)(shui)泵水(shui)(shui)(shui)(shui)輪發電(dian)(dian)電(dian)(dian)動機(ji)(ji)組，總裝機(ji)(ji)容量140萬千(qian)瓦(wa)(wa)，年設計發電(dian)(dian)量為23.42億千(qian)瓦(wa)(wa)時(shi)，抽(chou)(chou)水(shui)(shui)(shui)(shui)電(dian)(dian)量31.23億千(qian)瓦(wa)(wa)時(shi)，以500千(qian)伏出線接(jie)入吉(ji)林(lin)(lin)電(dian)(dian)網。中(zhong)國電(dian)(dian)建(jian)所屬北(bei)京院設計，水(shui)(shui)(shui)(shui)電(dian)(dian)六(liu)局、水(shui)(shui)(shui)(shui)電(dian)(dian)十一局、水(shui)(shui)(shui)(shui)電(dian)(dian)十四(si)局、水(shui)(shui)(shui)(shui)電(dian)(dian)十六(liu)局、電(dian)(dian)建(jian)建(jian)筑公司(si)承建(jian)了上下水(shui)(shui)(shui)(shui)庫大(da)壩、引水(shui)(shui)(shui)(shui)系統、通風兼出線洞(dong)(dong)、交通洞(dong)(dong)、自(zi)流(liu)排水(shui)(shui)(shui)(shui)洞(dong)(dong)、地下廠(chang)房及尾水(shui)(shui)(shui)(shui)系統、機(ji)(ji)電(dian)(dian)安裝等工(gong)程。

敦化電站的建(jian)(jian)設及(ji)投產，創造了國內抽(chou)水(shui)蓄能電站工(gong)程(cheng)建(jian)(jian)設的多(duo)項紀錄。其中，大壩(ba)主(zhu)體(ti)工(gong)程(cheng)在(zai)施工(gong)建(jian)(jian)設中，嚴(yan)控原(yuan)材(cai)料(liao)質(zhi)量(liang)關，優選骨(gu)料(liao)級配(pei)，精心開展配(pei)合比(bi)試驗，嚴(yan)格控制瀝青(qing)混凝土溫度(du)和密(mi)實度(du)，成功建(jian)(jian)設了嚴(yan)寒地(di)區抽(chou)水(shui)蓄能電站首(shou)個(ge)瀝青(qing)混凝土心墻堆石壩(ba)，大壩(ba)建(jian)(jian)設質(zhi)量(liang)優秀(xiu)，下(xia)水(shui)庫蓄水(shui)后大壩(ba)滲漏量(liang)僅為(wei)7升(sheng)每秒。

據悉，吉林敦化抽(chou)水(shui)蓄能(neng)電(dian)站(zhan)(zhan)是(shi)吉林省“十二五”規劃建(jian)設的(de)重點項目(mu)，是(shi)目(mu)前東北(bei)地區(qu)最(zui)大(da)(da)、吉林省首座純抽(chou)水(shui)蓄能(neng)電(dian)站(zhan)(zhan)，也是(shi)延邊州投資最(zui)大(da)(da)的(de)單體工程。該電(dian)站(zhan)(zhan)建(jian)成后，將有效緩(huan)解東北(bei)地區(qu)電(dian)網調(diao)節能(neng)力不(bu)足問題，充分(fen)發揮(hui)電(dian)力供應(ying)和(he)調(diao)峰(feng)填谷作用(yong)，為東北(bei)電(dian)網安全穩(wen)定運行和(he)促進新能(neng)源消納提(ti)供了更加(jia)堅強的(de)保障。
