10月(yue)17日，中國電建所屬水(shui)電八局承建的我國東北(bei)最大抽水(shui)蓄能電站——遼(liao)寧清(qing)原(yuan)抽水(shui)蓄能電站下水(shui)庫大壩提前封頂，為電站后續完工發(fa)電奠(dian)定了(le)堅(jian)實基礎。

下水(shui)(shui)庫大(da)(da)壩為混(hun)凝土(tu)面(mian)板(ban)堆石(shi)壩，1級建筑物，正常蓄水(shui)(shui)位319米，壩頂長375米，最大(da)(da)壩高49米，于5月截(jie)流(liu)、10月實現封頂，歷時5個月完(wan)成(cheng)施(shi)工任(ren)務(wu)。自大(da)(da)壩填(tian)(tian)筑以(yi)來(lai)，清原(yuan)項目部克服臺風等多方不利因素影響(xiang)，科學組織，精心施(shi)工，并通過成(cheng)立(li)“大(da)(da)壩填(tian)(tian)筑黨員先鋒崗”“下水(shui)(shui)庫大(da)(da)壩填(tian)(tian)筑專項小組”以(yi)及“大(da)(da)壩填(tian)(tian)筑青年突(tu)擊(ji)隊”，充分發揮先鋒模范(fan)作用，在保證安全施(shi)工的同時，提(ti)前達(da)到(dao)下水(shui)(shui)庫大(da)(da)壩填(tian)(tian)筑完(wan)成(cheng)的重要節點。

據了(le)解，清原(yuan)抽水(shui)蓄能電(dian)(dian)(dian)(dian)站(zhan)位(wei)于(yu)遼(liao)(liao)寧(ning)省(sheng)撫順市清原(yuan)滿族自治縣(xian)北三家鎮境內，是(shi)國家振興東(dong)北經濟139個項(xiang)目(mu)排(pai)名第一(yi)的(de)工(gong)程(cheng)，總裝(zhuang)機(ji)(ji)容(rong)量(liang)180萬千(qian)瓦(wa)，設計年(nian)發電(dian)(dian)(dian)(dian)量(liang)30億(yi)千(qian)瓦(wa)時(shi)，抽水(shui)電(dian)(dian)(dian)(dian)量(liang)40億(yi)千(qian)瓦(wa)時(shi)，為(wei)東(dong)北地區最(zui)大的(de)抽水(shui)蓄能電(dian)(dian)(dian)(dian)站(zhan)，也(ye)是(shi)目(mu)前全國在(zai)建水(shui)電(dian)(dian)(dian)(dian)裝(zhuang)機(ji)(ji)容(rong)量(liang)前三的(de)工(gong)程(cheng)。項(xiang)目(mu)建成后，將作(zuo)為(wei)重要“調節器”“穩(wen)(wen)壓器”和(he)“電(dian)(dian)(dian)(dian)力(li)糧倉”，在(zai)遼(liao)(liao)寧(ning)電(dian)(dian)(dian)(dian)網(wang)中(zhong)承擔調峰、填(tian)谷、調頻、調相、負荷備用(yong)和(he)緊急(ji)事故(gu)備用(yong)等任(ren)務，對保證遼(liao)(liao)寧(ning)電(dian)(dian)(dian)(dian)網(wang)和(he)東(dong)北電(dian)(dian)(dian)(dian)網(wang)安全穩(wen)(wen)定(ding)運(yun)行，有效吸納風電(dian)(dian)(dian)(dian)、光伏(fu)發電(dian)(dian)(dian)(dian)、核電(dian)(dian)(dian)(dian)等新能源(yuan)，進(jin)一(yi)步優化東(dong)北電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)源(yuan)結構起到重要作(zuo)用(yong)。
