12月(yue)22日，全國(guo)最大“線性菲涅爾”光(guang)(guang)熱(re)綜合能源(yuan)示范項目——三峽能源(yuan)哈密(mi)百萬千(qian)瓦“光(guang)(guang)熱(re)+光(guang)(guang)伏”一體化綜合能源(yuan)示范項目實(shi)現并網發電(dian)。

該項目(mu)位于新疆哈密市伊州區，總(zong)裝機(ji)容(rong)量100萬(wan)(wan)千(qian)瓦(wa)，規劃建設10萬(wan)(wan)千(qian)瓦(wa)的“線性菲涅爾”光(guang)(guang)(guang)(guang)熱儲(chu)(chu)(chu)能(neng)(neng)電(dian)(dian)站(zhan)(zhan)和90萬(wan)(wan)千(qian)瓦(wa)的光(guang)(guang)(guang)(guang)伏電(dian)(dian)站(zhan)(zhan)。目(mu)前，光(guang)(guang)(guang)(guang)伏電(dian)(dian)站(zhan)(zhan)已實現全部并網，光(guang)(guang)(guang)(guang)熱儲(chu)(chu)(chu)能(neng)(neng)電(dian)(dian)站(zhan)(zhan)正在加緊建設。其中光(guang)(guang)(guang)(guang)熱儲(chu)(chu)(chu)能(neng)(neng)電(dian)(dian)站(zhan)(zhan)共安裝反射鏡26萬(wan)(wan)塊，太陽(yang)能(neng)(neng)集熱面積80萬(wan)(wan)平方米，使用熔(rong)鹽作為(wei)儲(chu)(chu)(chu)存(cun)太陽(yang)能(neng)(neng)熱量的介質(zhi)，同時(shi)配置熔(rong)鹽儲(chu)(chu)(chu)熱系統，通(tong)過釋(shi)放(fang)熱能(neng)(neng)產生高(gao)溫(wen)高(gao)壓水蒸汽(qi)，驅動汽(qi)輪發(fa)電(dian)(dian)機(ji)，可(ke)實現8小時(shi)穩定發(fa)電(dian)(dian)。

據了解，“線性(xing)菲(fei)涅爾(er)”技術(shu)是目前(qian)光熱(re)儲能領(ling)域最前(qian)沿的技術(shu)路(lu)(lu)線之(zhi)一(yi)，利用光的反射和折射原理(li)，通(tong)過(guo)太陽能的轉化來發電，具有施(shi)工(gong)難(nan)度小、建設(she)周期(qi)短、維護(hu)方便、安全性(xing)高等優(you)點。該項目共安裝(zhuang)46條聚光集熱(re)回路(lu)(lu)，任何一(yi)條回路(lu)(lu)的檢(jian)修，不影響其他回路(lu)(lu)正常工(gong)作，大大提高了設(she)備的運行效率。

“‘光(guang)熱+光(guang)伏’的特點(dian)白(bai)天利用光(guang)伏發(fa)電(dian)(dian)，晚上(shang)采用光(guang)熱發(fa)電(dian)(dian)，促使發(fa)電(dian)(dian)出力平穩可(ke)控，提升電(dian)(dian)網(wang)對新能源的接納(na)能力。”項目經理牛建(jian)樂說。

項目全部并網(wang)后(hou)，光(guang)(guang)熱(re)儲能(neng)電(dian)(dian)站(zhan)將有效發(fa)揮基礎調節(jie)電(dian)(dian)源的調頻調峰作用，與光(guang)(guang)伏電(dian)(dian)站(zhan)共同(tong)形成多能(neng)互補清(qing)潔(jie)能(neng)源基地，預計年均發(fa)電(dian)(dian)量約18.6億千(qian)瓦(wa)時，每年可節(jie)約標準煤約55.87萬噸，減排二氧化(hua)碳(tan)超過150萬噸。
