2月19日，在哈密市伊(yi)州(zhou)區西山鄉，由三峽集(ji)團投資(zi)建設的哈密百萬(wan)千(qian)瓦“光熱+光伏(fu)”一體(ti)化綜(zong)合能源示范項目全(quan)面復工。

該項目(mu)總裝(zhuang)機容(rong)量(liang)100萬(wan)千瓦，分(fen)別為(wei)10萬(wan)千瓦“線性菲涅(nie)爾”光熱(re)儲能電(dian)站和90萬(wan)千瓦光伏電(dian)站。中國(guo)電(dian)力(li)工程(cheng)顧(gu)問集團西(xi)北電(dian)力(li)設(she)計院三峽(xia)哈密光熱(re)項目(mu)總包項目(mu)經(jing)理陳偉告訴記(ji)者，目(mu)前，現場施工人(ren)員已達(da)200人(ren)，已從人(ren)力(li)、設(she)備(bei)、資(zi)金各方(fang)面(mian)做好準備(bei)，在確(que)保(bao)安全的前提下保(bao)障進度目(mu)標(biao)順利完成。

在10萬(wan)千瓦“線性(xing)菲涅爾”光熱(re)(re)綜合能源(yuan)示范(fan)項(xiang)目(mu)的建設(she)現場(chang)，工人(ren)們正在安(an)裝光熱(re)(re)鏡(jing)場(chang)。記(ji)者了解到，該項(xiang)目(mu)集熱(re)(re)面積達80萬(wan)平方米，需要安(an)裝反射鏡(jing)26萬(wan)塊，這(zhe)成(cheng)為項(xiang)目(mu)復工后(hou)的重點工作，建設(she)單位通過(guo)加強人(ren)員(yuan)投入，優化組織，不斷提高建設(she)效率(lv)。

線性菲涅(nie)爾式(shi)太陽能熱發電(dian)系統是利(li)用近地安裝(zhuang)的多個一次(ci)反射(she)(she)(she)鏡，動態跟蹤日光(guang)軌(gui)跡，將(jiang)(jiang)日光(guang)反射(she)(she)(she)至高處的二次(ci)反射(she)(she)(she)鏡，再通(tong)過二次(ci)反射(she)(she)(she)鏡，將(jiang)(jiang)太陽輻(fu)射(she)(she)(she)聚集(ji)到(dao)真空集(ji)熱管(guan)，通(tong)過加熱吸熱流體，以熱力循環進(jin)行(xing)發電(dian)的系統，具有建設成本(ben)較低(di)，維護便利(li)的特(te)點。
