近(jin)日，國(guo)家電網公司科技(ji)項目“接(jie)入城市供(gong)電網百千(qian)瓦級屋頂太陽(yang)能光(guang)伏并網電站(zhan)試(shi)驗平臺研究與實(shi)施”通過驗收，標(biao)志著(zhu)國(guo)內首次在既有框(kuang)架(jia)結構(gou)高層建(jian)筑上建(jian)設(she)大(da)型光(guang)伏系(xi)統工程(cheng)取(qu)得(de)成功，為(wei)推動太陽(yang)能大(da)規模開發利用以及(ji)光(guang)伏發電項目并網運行(xing)提(ti)供(gong)了重要技(ji)術支持。
為(wei)有效促進(jin)節能(neng)(neng)減(jian)(jian)排，國(guo)家(jia)電(dian)(dian)(dian)網公(gong)司積極開展太陽能(neng)(neng)等(deng)新能(neng)(neng)源(yuan)發(fa)(fa)(fa)電(dian)(dian)(dian)項(xiang)目建設及并(bing)(bing)(bing)(bing)網研(yan)究(jiu)。國(guo)家(jia)電(dian)(dian)(dian)網在對分布式電(dian)(dian)(dian)源(yuan)發(fa)(fa)(fa)電(dian)(dian)(dian)和并(bing)(bing)(bing)(bing)網等(deng)一系(xi)列理論(lun)研(yan)究(jiu)的(de)(de)基礎上(shang)，于(yu)去(qu)年(nian)底在所(suo)屬浙江省(sheng)電(dian)(dian)(dian)力公(gong)司生產(chan)調度大樓(lou)屋頂分別建設了一座單相5千瓦(wa)(wa)光(guang)伏(fu)220伏(fu)并(bing)(bing)(bing)(bing)網試(shi)驗(yan)電(dian)(dian)(dian)站(zhan)、一座250千瓦(wa)(wa)光(guang)伏(fu)10千伏(fu)高壓并(bing)(bing)(bing)(bing)網示范電(dian)(dian)(dian)站(zhan)和一座60千瓦(wa)(wa)光(guang)伏(fu)三相400伏(fu)并(bing)(bing)(bing)(bing)網電(dian)(dian)(dian)站(zhan)，并(bing)(bing)(bing)(bing)開發(fa)(fa)(fa)研(yan)制(zhi)了多功能(neng)(neng)光(guang)伏(fu)發(fa)(fa)(fa)電(dian)(dian)(dian)并(bing)(bing)(bing)(bing)網系(xi)統(tong)試(shi)驗(yan)平臺(tai)，對光(guang)伏(fu)并(bing)(bing)(bing)(bing)網發(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)安全性能(neng)(neng)、運(yun)行效率(lv)等(deng)進(jin)行全面細致的(de)(de)試(shi)驗(yan)研(yan)究(jiu)，針(zhen)對太陽能(neng)(neng)發(fa)(fa)(fa)電(dian)(dian)(dian)特點，制(zhi)定(ding)了確保電(dian)(dian)(dian)網安全穩定(ding)運(yun)行的(de)(de)光(guang)伏(fu)系(xi)統(tong)并(bing)(bing)(bing)(bing)網技術規范。三座電(dian)(dian)(dian)站(zhan)于(yu)今年(nian)1月2日正式并(bing)(bing)(bing)(bing)網投入運(yun)行，截至(zhi)4月28日，已累計(ji)發(fa)(fa)(fa)電(dian)(dian)(dian)807小時(shi)，發(fa)(fa)(fa)電(dian)(dian)(dian)5.52萬(wan)(wan)千瓦(wa)(wa)時(shi)，減(jian)(jian)少二(er)氧化(hua)碳(tan)排放3.1噸(dun)，運(yun)行狀態良好(hao)，系(xi)統(tong)穩定(ding)。與(yu)采(cai)用玻(bo)璃幕墻的(de)(de)一體(ti)化(hua)光(guang)電(dian)(dian)(dian)建筑不同，該大型(xing)光(guang)伏(fu)電(dian)(dian)(dian)站(zhan)系(xi)統(tong)與(yu)建筑物本身物理分離，市場推廣(guang)應用范圍十分廣(guang)闊。據測算，該系(xi)統(tong)年(nian)發(fa)(fa)(fa)電(dian)(dian)(dian)能(neng)(neng)力預計(ji)約(yue)為(wei)30萬(wan)(wan)千瓦(wa)(wa)時(shi)，每年(nian)可減(jian)(jian)排二(er)氧化(hua)碳(tan)約(yue)17萬(wan)(wan)噸(dun)，減(jian)(jian)排氧化(hua)氮(dan)約(yue)22萬(wan)(wan)噸(dun)，產(chan)生電(dian)(dian)(dian)費(fei)收(shou)入近(jin)120萬(wan)(wan)元(yuan)。
