山東省(sheng)青州(zhou)市魯東機械2.1MW光伏(fu)發(fa)電(dian)站項目。彩鋼(gang)瓦屋頂光伏(fu)發(fa)電(dian)站，已并網發(fa)電(dian)成功！

輸送方式

太陽能(neng)光伏(fu)發(fa)電分(fen)為獨立光伏(fu)發(fa)電、并網光伏(fu)發(fa)電、分(fen)布式光伏(fu)發(fa)電

獨立光伏發電

獨立光伏(fu)發電系(xi)統也叫離網光伏(fu)發電系(xi)統。主(zhu)要(yao)由太(tai)陽能電池(chi)組件(jian)、控(kong)制器、蓄電池(chi)組成，若要(yao)為交(jiao)流負載供電，還(huan)需要(yao)配置交(jiao)流逆變器。

并網光伏發電

并(bing)網(wang)(wang)(wang)(wang)(wang)光伏(fu)(fu)發(fa)(fa)電(dian)(dian)系(xi)(xi)統(tong)就是(shi)(shi)太陽能組件產生的直(zhi)流(liu)(liu)電(dian)(dian)經過并(bing)網(wang)(wang)(wang)(wang)(wang)逆(ni)變器轉換成(cheng)符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)(wang)(wang)要求的交流(liu)(liu)電(dian)(dian)之后直(zhi)接接入(ru)公共電(dian)(dian)網(wang)(wang)(wang)(wang)(wang)。并(bing)網(wang)(wang)(wang)(wang)(wang)光伏(fu)(fu)發(fa)(fa)電(dian)(dian)系(xi)(xi)統(tong)有集中式大型并(bing)網(wang)(wang)(wang)(wang)(wang)光伏(fu)(fu)電(dian)(dian)站(zhan)一般都是(shi)(shi)國家(jia)級電(dian)(dian)站(zhan)，主要特(te)點(dian)是(shi)(shi)將所(suo)發(fa)(fa)電(dian)(dian)能直(zhi)接輸送到電(dian)(dian)網(wang)(wang)(wang)(wang)(wang)，由(you)電(dian)(dian)網(wang)(wang)(wang)(wang)(wang)統(tong)一調配向用戶供電(dian)(dian)。但這種電(dian)(dian)站(zhan)投(tou)資(zi)(zi)大、建(jian)(jian)設周期長(chang)、占地面積(ji)大，發(fa)(fa)展難(nan)度(du)相對較大。而(er)分(fen)散式小型并(bing)網(wang)(wang)(wang)(wang)(wang)光伏(fu)(fu)系(xi)(xi)統(tong)，特(te)別是(shi)(shi)光伏(fu)(fu)建(jian)(jian)筑一體化發(fa)(fa)電(dian)(dian)系(xi)(xi)統(tong)，由(you)于投(tou)資(zi)(zi)小、建(jian)(jian)設快、占地面積(ji)小、政策支持力度(du)大等優點(dian)，是(shi)(shi)并(bing)網(wang)(wang)(wang)(wang)(wang)光伏(fu)(fu)發(fa)(fa)電(dian)(dian)的主流(liu)(liu)。

分布式光伏發電

分布式光伏(fu)發電(dian)系統(tong)，又稱分散(san)式發電(dian)或分布式供能，是指在用(yong)戶現(xian)(xian)場(chang)或靠近用(yong)電(dian)現(xian)(xian)場(chang)配置較(jiao)小(xiao)的光伏(fu)發電(dian)供電(dian)系統(tong)，以滿足特定用(yong)戶的需求，支持現(xian)(xian)存配電(dian)網(wang)的經濟運行，或者(zhe)同時滿足這兩個(ge)方面的要求。

　　分布式(shi)(shi)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)(dian)系統的(de)(de)基(ji)本設(she)(she)備(bei)包括光(guang)伏(fu)(fu)電(dian)(dian)(dian)(dian)池組(zu)(zu)件、光(guang)伏(fu)(fu)方陣(zhen)支(zhi)架、直流(liu)(liu)匯流(liu)(liu)箱、直流(liu)(liu)配電(dian)(dian)(dian)(dian)柜、并(bing)網逆(ni)變(bian)器(qi)、交流(liu)(liu)配電(dian)(dian)(dian)(dian)柜等設(she)(she)備(bei)，另外還有供(gong)電(dian)(dian)(dian)(dian)系統監控裝置和環(huan)境監測裝置。其(qi)運行模式(shi)(shi)是在有太(tai)(tai)陽輻(fu)射的(de)(de)條件下，光(guang)伏(fu)(fu)發電(dian)(dian)(dian)(dian)系統的(de)(de)太(tai)(tai)陽能電(dian)(dian)(dian)(dian)池組(zu)(zu)件陣(zhen)列將(jiang)太(tai)(tai)陽能轉(zhuan)換輸出的(de)(de)電(dian)(dian)(dian)(dian)能，經過(guo)直流(liu)(liu)匯流(liu)(liu)箱集中送入直流(liu)(liu)配電(dian)(dian)(dian)(dian)柜，由(you)并(bing)網逆(ni)變(bian)器(qi)逆(ni)變(bian)成(cheng)交流(liu)(liu)電(dian)(dian)(dian)(dian)供(gong)給建筑自身負載(zai)，多余或不(bu)足的(de)(de)電(dian)(dian)(dian)(dian)力通(tong)過(guo)聯接電(dian)(dian)(dian)(dian)網來調節。
