10月17日(ri)，中國電(dian)建所屬水(shui)(shui)電(dian)八局承建的我國東(dong)北(bei)最大抽(chou)(chou)水(shui)(shui)蓄(xu)能(neng)電(dian)站(zhan)——遼(liao)寧清原抽(chou)(chou)水(shui)(shui)蓄(xu)能(neng)電(dian)站(zhan)下水(shui)(shui)庫(ku)大壩提(ti)前封頂，為(wei)電(dian)站(zhan)后續(xu)完工發電(dian)奠定(ding)了堅實基礎(chu)。

下水(shui)庫(ku)大壩(ba)(ba)為混凝土面板(ban)堆(dui)石壩(ba)(ba)，1級(ji)建筑(zhu)物，正常(chang)蓄水(shui)位319米(mi)(mi)，壩(ba)(ba)頂長375米(mi)(mi)，最大壩(ba)(ba)高49米(mi)(mi)，于5月截(jie)流、10月實現封(feng)頂，歷(li)時5個月完(wan)成施工(gong)任務。自(zi)大壩(ba)(ba)填筑(zhu)以來，清原項(xiang)目部克服臺(tai)風(feng)等多方不(bu)利因素(su)影響，科(ke)學組(zu)織，精心施工(gong)，并通(tong)過成立“大壩(ba)(ba)填筑(zhu)黨(dang)員先鋒崗”“下水(shui)庫(ku)大壩(ba)(ba)填筑(zhu)專項(xiang)小組(zu)”以及“大壩(ba)(ba)填筑(zhu)青年突擊隊”，充分發揮(hui)先鋒模范作用，在(zai)保證安全施工(gong)的同時，提前達到下水(shui)庫(ku)大壩(ba)(ba)填筑(zhu)完(wan)成的重(zhong)要節點。

據(ju)了解，清原抽水蓄能電(dian)(dian)(dian)(dian)站位于遼(liao)寧(ning)省撫(fu)順(shun)市清原滿族自治(zhi)縣(xian)北(bei)(bei)三(san)家鎮境內，是國家振興東(dong)北(bei)(bei)經濟139個項目排名(ming)第一的(de)工(gong)程(cheng)，總裝(zhuang)機容量180萬(wan)千(qian)瓦，設計年發電(dian)(dian)(dian)(dian)量30億千(qian)瓦時，抽水電(dian)(dian)(dian)(dian)量40億千(qian)瓦時，為東(dong)北(bei)(bei)地區最大的(de)抽水蓄能電(dian)(dian)(dian)(dian)站，也是目前全(quan)國在建(jian)水電(dian)(dian)(dian)(dian)裝(zhuang)機容量前三(san)的(de)工(gong)程(cheng)。項目建(jian)成后，將作為重(zhong)要(yao)“調(diao)(diao)節器(qi)”“穩壓器(qi)”和“電(dian)(dian)(dian)(dian)力糧倉(cang)”，在遼(liao)寧(ning)電(dian)(dian)(dian)(dian)網(wang)中承擔調(diao)(diao)峰、填谷、調(diao)(diao)頻、調(diao)(diao)相、負荷備用和緊急事(shi)故備用等任務(wu)，對保證遼(liao)寧(ning)電(dian)(dian)(dian)(dian)網(wang)和東(dong)北(bei)(bei)電(dian)(dian)(dian)(dian)網(wang)安(an)全(quan)穩定運行，有效吸納風電(dian)(dian)(dian)(dian)、光伏發電(dian)(dian)(dian)(dian)、核電(dian)(dian)(dian)(dian)等新能源(yuan)，進一步優化東(dong)北(bei)(bei)電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)源(yuan)結構起(qi)到重(zhong)要(yao)作用。
