近日，國家(jia)電網(wang)(wang)公(gong)司(si)科(ke)技項目“接入(ru)城市供(gong)電網(wang)(wang)百千瓦級屋頂太(tai)陽能(neng)光(guang)伏并網(wang)(wang)電站試驗平(ping)臺研究與實施(shi)”通過驗收，標志著國內(nei)首次在既有框(kuang)架(jia)結構高(gao)層建(jian)筑上建(jian)設大型光(guang)伏系統工程取得成功(gong)，為推動太(tai)陽能(neng)大規模開發利(li)用(yong)以及光(guang)伏發電項目并網(wang)(wang)運行提供(gong)了重要技術支持。
為有效(xiao)(xiao)促進節能減(jian)(jian)排，國家電(dian)(dian)(dian)網(wang)(wang)(wang)公司(si)積極(ji)開展太(tai)陽能等(deng)新(xin)能源發(fa)(fa)電(dian)(dian)(dian)項目建設(she)及并(bing)(bing)(bing)網(wang)(wang)(wang)研究。國家電(dian)(dian)(dian)網(wang)(wang)(wang)在對(dui)分(fen)布式電(dian)(dian)(dian)源發(fa)(fa)電(dian)(dian)(dian)和并(bing)(bing)(bing)網(wang)(wang)(wang)等(deng)一系(xi)(xi)(xi)列理(li)論研究的(de)基礎上，于去(qu)年(nian)底在所屬浙江(jiang)省電(dian)(dian)(dian)力公司(si)生(sheng)產調度大(da)樓(lou)屋頂分(fen)別建設(she)了(le)(le)一座(zuo)(zuo)(zuo)(zuo)單相5千(qian)(qian)瓦(wa)光(guang)伏220伏并(bing)(bing)(bing)網(wang)(wang)(wang)試(shi)驗(yan)電(dian)(dian)(dian)站(zhan)、一座(zuo)(zuo)(zuo)(zuo)250千(qian)(qian)瓦(wa)光(guang)伏10千(qian)(qian)伏高壓并(bing)(bing)(bing)網(wang)(wang)(wang)示范(fan)電(dian)(dian)(dian)站(zhan)和一座(zuo)(zuo)(zuo)(zuo)60千(qian)(qian)瓦(wa)光(guang)伏三相400伏并(bing)(bing)(bing)網(wang)(wang)(wang)電(dian)(dian)(dian)站(zhan)，并(bing)(bing)(bing)開發(fa)(fa)研制了(le)(le)多(duo)功(gong)能光(guang)伏發(fa)(fa)電(dian)(dian)(dian)并(bing)(bing)(bing)網(wang)(wang)(wang)系(xi)(xi)(xi)統(tong)試(shi)驗(yan)平臺，對(dui)光(guang)伏并(bing)(bing)(bing)網(wang)(wang)(wang)發(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統(tong)安(an)全(quan)性能、運行效(xiao)(xiao)率等(deng)進行全(quan)面細致的(de)試(shi)驗(yan)研究，針對(dui)太(tai)陽能發(fa)(fa)電(dian)(dian)(dian)特點，制定了(le)(le)確(que)保電(dian)(dian)(dian)網(wang)(wang)(wang)安(an)全(quan)穩定運行的(de)光(guang)伏系(xi)(xi)(xi)統(tong)并(bing)(bing)(bing)網(wang)(wang)(wang)技術規范(fan)。三座(zuo)(zuo)(zuo)(zuo)電(dian)(dian)(dian)站(zhan)于今年(nian)1月2日正式并(bing)(bing)(bing)網(wang)(wang)(wang)投入運行，截至4月28日，已累計發(fa)(fa)電(dian)(dian)(dian)807小(xiao)時(shi)，發(fa)(fa)電(dian)(dian)(dian)5.52萬(wan)(wan)(wan)千(qian)(qian)瓦(wa)時(shi)，減(jian)(jian)少二(er)氧(yang)化碳(tan)排放3.1噸，運行狀態(tai)良(liang)好(hao)，系(xi)(xi)(xi)統(tong)穩定。與采(cai)用玻璃(li)幕墻的(de)一體化光(guang)電(dian)(dian)(dian)建筑(zhu)不同(tong)，該大(da)型光(guang)伏電(dian)(dian)(dian)站(zhan)系(xi)(xi)(xi)統(tong)與建筑(zhu)物(wu)本(ben)身物(wu)理(li)分(fen)離，市場推廣(guang)應(ying)用范(fan)圍十分(fen)廣(guang)闊。據測算，該系(xi)(xi)(xi)統(tong)年(nian)發(fa)(fa)電(dian)(dian)(dian)能力預(yu)計約為30萬(wan)(wan)(wan)千(qian)(qian)瓦(wa)時(shi)，每年(nian)可減(jian)(jian)排二(er)氧(yang)化碳(tan)約17萬(wan)(wan)(wan)噸，減(jian)(jian)排氧(yang)化氮約22萬(wan)(wan)(wan)噸，產生(sheng)電(dian)(dian)(dian)費收入近120萬(wan)(wan)(wan)元。
