山(shan)東(dong)省青州(zhou)市魯(lu)東(dong)機械(xie)2.1MW光(guang)伏(fu)(fu)發電(dian)站項目。彩鋼瓦屋頂光(guang)伏(fu)(fu)發電(dian)站，已(yi)并(bing)網發電(dian)成功(gong)！

輸送方式

太陽能光伏(fu)發(fa)電(dian)分為(wei)獨立光伏(fu)發(fa)電(dian)、并網光伏(fu)發(fa)電(dian)、分布式光伏(fu)發(fa)電(dian)

獨立光伏發電

獨(du)立光伏(fu)發電系統(tong)也叫離(li)網光伏(fu)發電系統(tong)。主要由太陽能電池組件、控制器、蓄(xu)電池組成，若要為交流負(fu)載供電，還需要配置交流逆變器。

并網光伏發電

并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)(fa)(fa)電(dian)系統就是(shi)太陽能組件產(chan)生的(de)直(zhi)流(liu)(liu)電(dian)經過(guo)并(bing)網(wang)(wang)(wang)逆變(bian)器轉(zhuan)換成(cheng)符合市電(dian)電(dian)網(wang)(wang)(wang)要求(qiu)的(de)交(jiao)流(liu)(liu)電(dian)之后直(zhi)接(jie)(jie)(jie)接(jie)(jie)(jie)入(ru)公共電(dian)網(wang)(wang)(wang)。并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)(fa)(fa)電(dian)系統有(you)集中式大型并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)電(dian)站一(yi)般都是(shi)國家級電(dian)站，主要特點是(shi)將(jiang)所發(fa)(fa)(fa)電(dian)能直(zhi)接(jie)(jie)(jie)輸送到(dao)電(dian)網(wang)(wang)(wang)，由電(dian)網(wang)(wang)(wang)統一(yi)調配向用戶供電(dian)。但這種(zhong)電(dian)站投(tou)資大、建設周期長、占地面積大，發(fa)(fa)(fa)展(zhan)難度相對較大。而(er)分散式小(xiao)型并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)系統，特別是(shi)光(guang)(guang)伏(fu)(fu)建筑一(yi)體化(hua)發(fa)(fa)(fa)電(dian)系統，由于投(tou)資小(xiao)、建設快、占地面積小(xiao)、政策支持力(li)度大等優點，是(shi)并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)(fa)(fa)電(dian)的(de)主流(liu)(liu)。

分布式光伏發電

分布式光伏(fu)發電(dian)(dian)(dian)(dian)系(xi)(xi)統，又稱分散式發電(dian)(dian)(dian)(dian)或分布式供(gong)能(neng)，是指(zhi)在用(yong)戶現場或靠近用(yong)電(dian)(dian)(dian)(dian)現場配置(zhi)較小的(de)光伏(fu)發電(dian)(dian)(dian)(dian)供(gong)電(dian)(dian)(dian)(dian)系(xi)(xi)統，以滿足(zu)特定(ding)用(yong)戶的(de)需求(qiu)，支(zhi)持現存配電(dian)(dian)(dian)(dian)網的(de)經濟運行，或者(zhe)同時滿足(zu)這兩個方面的(de)要求(qiu)。
