山東(dong)省青州(zhou)市魯東(dong)機械2.1MW光伏發(fa)電(dian)站(zhan)項目。彩鋼瓦屋頂光伏發(fa)電(dian)站(zhan)，已并網發(fa)電(dian)成功！

輸送方式

太陽能光伏(fu)發(fa)(fa)電(dian)分(fen)為獨立光伏(fu)發(fa)(fa)電(dian)、并網光伏(fu)發(fa)(fa)電(dian)、分(fen)布(bu)式(shi)光伏(fu)發(fa)(fa)電(dian)

獨立光伏發電

獨(du)立光(guang)伏發(fa)電(dian)系(xi)統也叫(jiao)離網光(guang)伏發(fa)電(dian)系(xi)統。主要由太陽能電(dian)池組(zu)件(jian)、控制器(qi)、蓄(xu)電(dian)池組(zu)成，若要為交流負載供電(dian)，還(huan)需要配(pei)置交流逆變器(qi)。

并網光伏發電

并(bing)(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)發電(dian)(dian)系統(tong)(tong)就(jiu)是(shi)太陽(yang)能組件產生的直流電(dian)(dian)經過(guo)并(bing)(bing)網(wang)(wang)(wang)逆(ni)變(bian)器(qi)轉換成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)要求的交流電(dian)(dian)之后直接(jie)(jie)接(jie)(jie)入(ru)公共(gong)電(dian)(dian)網(wang)(wang)(wang)。并(bing)(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)發電(dian)(dian)系統(tong)(tong)有集中(zhong)式(shi)大(da)型并(bing)(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)電(dian)(dian)站一般都是(shi)國家(jia)級電(dian)(dian)站，主(zhu)要特點(dian)是(shi)將所發電(dian)(dian)能直接(jie)(jie)輸送到(dao)電(dian)(dian)網(wang)(wang)(wang)，由(you)電(dian)(dian)網(wang)(wang)(wang)統(tong)(tong)一調配向用戶(hu)供電(dian)(dian)。但這種電(dian)(dian)站投(tou)(tou)資大(da)、建設周期長、占地(di)面積大(da)，發展難(nan)度相對較大(da)。而(er)分散式(shi)小(xiao)型并(bing)(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)系統(tong)(tong)，特別是(shi)光(guang)伏(fu)(fu)建筑一體(ti)化發電(dian)(dian)系統(tong)(tong)，由(you)于投(tou)(tou)資小(xiao)、建設快、占地(di)面積小(xiao)、政策支持力(li)度大(da)等優點(dian)，是(shi)并(bing)(bing)網(wang)(wang)(wang)光(guang)伏(fu)(fu)發電(dian)(dian)的主(zhu)流。

分布式光伏發電

分(fen)布(bu)式光伏(fu)發(fa)(fa)電(dian)系統，又稱分(fen)散式發(fa)(fa)電(dian)或(huo)分(fen)布(bu)式供(gong)能(neng)，是指在用(yong)戶(hu)現(xian)場或(huo)靠近(jin)用(yong)電(dian)現(xian)場配置較(jiao)小的(de)(de)光伏(fu)發(fa)(fa)電(dian)供(gong)電(dian)系統，以滿足特定用(yong)戶(hu)的(de)(de)需求，支持現(xian)存配電(dian)網的(de)(de)經(jing)濟運行，或(huo)者同時滿足這(zhe)兩個方面的(de)(de)要求。

　　分布(bu)式光(guang)伏(fu)(fu)發電(dian)系(xi)統(tong)(tong)的基本設(she)備(bei)包括光(guang)伏(fu)(fu)電(dian)池組件、光(guang)伏(fu)(fu)方陣支架、直流(liu)(liu)匯(hui)流(liu)(liu)箱、直流(liu)(liu)配(pei)電(dian)柜(ju)、并網(wang)逆變(bian)器(qi)、交流(liu)(liu)配(pei)電(dian)柜(ju)等設(she)備(bei)，另外還有供(gong)電(dian)系(xi)統(tong)(tong)監控裝置和環境監測裝置。其(qi)運行(xing)模(mo)式是在有太陽輻射的條件下，光(guang)伏(fu)(fu)發電(dian)系(xi)統(tong)(tong)的太陽能電(dian)池組件陣列將太陽能轉換輸出的電(dian)能，經過直流(liu)(liu)匯(hui)流(liu)(liu)箱集中(zhong)送入直流(liu)(liu)配(pei)電(dian)柜(ju)，由并網(wang)逆變(bian)器(qi)逆變(bian)成(cheng)交流(liu)(liu)電(dian)供(gong)給建筑(zhu)自身負載，多余或不足的電(dian)力通過聯接(jie)電(dian)網(wang)來調節。
