三峽電站2020年累計發電量破世界紀錄

時間:2021-01-05 16:22:37 點擊次數:

       在確保三峽工程(cheng)全面(mian)發揮防洪、航運(yun)、水(shui)資源(yuan)利(li)用等綜(zong)合效益的(de)前(qian)提(ti)下,世(shi)界裝機規模最大水(shui)電(dian)站(zhan)——三峽電(dian)站(zhan),全年累(lei)計生產清潔電(dian)能1118億(yi)千瓦時,打破了此前(qian)南美洲伊泰普水(shui)電(dian)站(zhan)于(yu)2016年創(chuang)造并(bing)保持的(de)1030.98億(yi)千瓦時的(de)單座水(shui)電(dian)站(zhan)年發電(dian)量世(shi)界紀錄,是(shi)中國水(shui)電(dian)引(yin)領世(shi)界的(de)重要標志。

  按(an)照2019年(nian)上海全市用電(dian)量1568.58億千(qian)瓦時計(ji)算,1118億千(qian)瓦時清(qing)潔電(dian)能,可供上海市用電(dian)約(yue)8個(ge)月;與燃煤發電(dian)相比,可替代(dai)標準煤約(yue)3439萬(wan)(wan)噸,減排(pai)(pai)二(er)(er)(er)氧化(hua)碳(tan)(tan)(tan)約(yue)9402萬(wan)(wan)噸、二(er)(er)(er)氧化(hua)硫2.24萬(wan)(wan)噸、氮氧化(hua)物2.12萬(wan)(wan)噸,相當(dang)于種植37萬(wan)(wan)公頃闊葉林,為我國(guo)構建清(qing)潔低碳(tan)(tan)(tan)、安全高效的能源體系(xi),力爭在2030年(nian)前實現(xian)二(er)(er)(er)氧化(hua)碳(tan)(tan)(tan)排(pai)(pai)放達峰值,2060年(nian)前實現(xian)碳(tan)(tan)(tan)中和作出了三峽貢獻。

  2020年(nian)初,在疫(yi)情防控(kong)關鍵階段,三峽電(dian)(dian)站持續(xu)加大電(dian)(dian)站出力(li)(li)(li)(li)和(he)調峰量(liang),送往華東、華中、南(nan)方等省(sheng)市的清潔電(dian)(dian)能達(da)到歷史同期最高值,為我(wo)國(guo)(guo)疫(yi)情防控(kong)和(he)復(fu)工復(fu)產提供(gong)了強有(you)力(li)(li)(li)(li)的基礎能源(yuan)保(bao)障。按每千瓦(wa)(wa)時(shi)電(dian)(dian)量(liang)可(ke)產生13.8元(yuan)GDP推算,全年(nian)1118億(yi)千瓦(wa)(wa)時(shi)電(dian)(dian)量(liang),可(ke)支撐我(wo)國(guo)(guo)約1.54萬億(yi)元(yuan)GDP,為國(guo)(guo)民經濟復(fu)蘇提供(gong)了強有(you)力(li)(li)(li)(li)的電(dian)(dian)力(li)(li)(li)(li)保(bao)障。

  防洪(hong)是三(san)峽(xia)(xia)工(gong)(gong)程的(de)首要任(ren)務。2020年(nian)汛(xun)(xun)期,長江(jiang)流域共發生5次(ci)編號洪(hong)水(shui)(shui)(shui),最大洪(hong)峰達(da)75000立方米每秒。在(zai)水(shui)(shui)(shui)利(li)部長江(jiang)水(shui)(shui)(shui)利(li)委員會等的(de)指導(dao)下(xia)(xia),中國長江(jiang)三(san)峽(xia)(xia)集團有限(xian)公司嚴格落(luo)實汛(xun)(xun)期三(san)峽(xia)(xia)工(gong)(gong)程各項風險管(guan)控(kong)措(cuo)施,優化三(san)峽(xia)(xia)電(dian)站(zhan)機(ji)組(zu)運(yun)行工(gong)(gong)況,為電(dian)站(zhan)防洪(hong)度汛(xun)(xun)和安(an)全發電(dian)打(da)下(xia)(xia)基礎,機(ji)組(zu)設備可控(kong),三(san)峽(xia)(xia)工(gong)(gong)程始終處于(yu)安(an)全穩定運(yun)行狀態。

  2020年(nian)(nian)12月以來,受(shou)寒潮(chao)影響,三峽電(dian)站部分受(shou)電(dian)區(qu)域氣溫偏低,采暖用電(dian)負荷加速釋(shi)放,電(dian)力供應(ying)缺口大。三峽電(dian)站積極開展“抗寒潮(chao)、保供電(dian)”迎峰度冬工(gong)作,2020年(nian)(nian)12月12日至30日緊急調整運行方式,合(he)理安排機組檢(jian)修,高峰期增(zeng)開機組8臺,出(chu)力最大達(da)1411萬千瓦(wa),日均出(chu)力較寒潮(chao)前最大增(zeng)加329萬千瓦(wa),累計發電(dian)量(liang)超過(guo)37億千瓦(wa)時(shi)(shi);2020年(nian)(nian)12月全月發電(dian)量(liang)較2019年(nian)(nian)同期增(zeng)加約4.9億千瓦(wa)時(shi)(shi),可供49萬個三口之家用電(dian)1年(nian)(nian)(以三口之家年(nian)(nian)用電(dian)量(liang)1000千瓦(wa)時(shi)(shi)計算(suan)),及(ji)時(shi)(shi)彌補(bu)了用電(dian)缺口。

  三(san)峽電(dian)(dian)(dian)(dian)站(zhan)是我國“西電(dian)(dian)(dian)(dian)東送”和“南(nan)北互供”骨(gu)干電(dian)(dian)(dian)(dian)源點(dian),共安裝(zhuang)34臺水輪(lun)發電(dian)(dian)(dian)(dian)機組(zu),總(zong)裝(zhuang)機容量(liang)(liang)2250萬千(qian)(qian)瓦,年(nian)(nian)(nian)設計發電(dian)(dian)(dian)(dian)量(liang)(liang)882億(yi)千(qian)(qian)瓦時(shi),2003年(nian)(nian)(nian)首批機組(zu)投產發電(dian)(dian)(dian)(dian)。2014年(nian)(nian)(nian),三(san)峽電(dian)(dian)(dian)(dian)站(zhan)年(nian)(nian)(nian)發電(dian)(dian)(dian)(dian)量(liang)(liang)達(da)(da)988億(yi)千(qian)(qian)瓦時(shi),超過伊泰普水電(dian)(dian)(dian)(dian)站(zhan),創當年(nian)(nian)(nian)單座水電(dian)(dian)(dian)(dian)站(zhan)年(nian)(nian)(nian)發電(dian)(dian)(dian)(dian)量(liang)(liang)世界紀錄;2018年(nian)(nian)(nian),年(nian)(nian)(nian)發電(dian)(dian)(dian)(dian)量(liang)(liang)達(da)(da)1016億(yi)千(qian)(qian)瓦時(shi),首次突破(po)1000億(yi)千(qian)(qian)瓦時(shi)大關。
