山東省青州市魯東機械2.1MW光伏發電(dian)站項(xiang)目。彩鋼(gang)瓦屋頂光伏發電(dian)站，已并網發電(dian)成功！

輸送方式

太陽能光(guang)伏發(fa)(fa)電分為獨立光(guang)伏發(fa)(fa)電、并網(wang)光(guang)伏發(fa)(fa)電、分布(bu)式光(guang)伏發(fa)(fa)電

獨立光伏發電

獨立光伏發(fa)電系(xi)統(tong)也叫離網光伏發(fa)電系(xi)統(tong)。主要(yao)由太陽能電池組件、控制器、蓄電池組成，若(ruo)要(yao)為交(jiao)流(liu)負載供電，還需要(yao)配置交(jiao)流(liu)逆變(bian)器。

并網光伏發電

并(bing)(bing)網(wang)(wang)(wang)(wang)光(guang)(guang)伏發(fa)電(dian)(dian)系(xi)統就是(shi)太陽(yang)能組件產(chan)生的(de)(de)直流電(dian)(dian)經過并(bing)(bing)網(wang)(wang)(wang)(wang)逆變器轉換(huan)成符合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)(wang)要求(qiu)的(de)(de)交流電(dian)(dian)之后(hou)直接接入公共電(dian)(dian)網(wang)(wang)(wang)(wang)。并(bing)(bing)網(wang)(wang)(wang)(wang)光(guang)(guang)伏發(fa)電(dian)(dian)系(xi)統有集中(zhong)式大(da)型并(bing)(bing)網(wang)(wang)(wang)(wang)光(guang)(guang)伏電(dian)(dian)站(zhan)一(yi)般都是(shi)國(guo)家級電(dian)(dian)站(zhan)，主要特(te)點(dian)是(shi)將所(suo)發(fa)電(dian)(dian)能直接輸送到電(dian)(dian)網(wang)(wang)(wang)(wang)，由電(dian)(dian)網(wang)(wang)(wang)(wang)統一(yi)調配向用戶(hu)供電(dian)(dian)。但這種電(dian)(dian)站(zhan)投資大(da)、建設(she)周期長(chang)、占地面(mian)積(ji)大(da)，發(fa)展難度(du)相對較大(da)。而分散(san)式小(xiao)型并(bing)(bing)網(wang)(wang)(wang)(wang)光(guang)(guang)伏系(xi)統，特(te)別是(shi)光(guang)(guang)伏建筑(zhu)一(yi)體(ti)化發(fa)電(dian)(dian)系(xi)統，由于投資小(xiao)、建設(she)快、占地面(mian)積(ji)小(xiao)、政(zheng)策支持力度(du)大(da)等優點(dian)，是(shi)并(bing)(bing)網(wang)(wang)(wang)(wang)光(guang)(guang)伏發(fa)電(dian)(dian)的(de)(de)主流。

分布式光伏發電

分(fen)布(bu)式(shi)光伏發電(dian)(dian)(dian)系統，又稱分(fen)散式(shi)發電(dian)(dian)(dian)或分(fen)布(bu)式(shi)供能(neng)，是(shi)指在用戶(hu)現場(chang)或靠近用電(dian)(dian)(dian)現場(chang)配置較(jiao)小的(de)(de)光伏發電(dian)(dian)(dian)供電(dian)(dian)(dian)系統，以滿(man)足特定用戶(hu)的(de)(de)需(xu)求，支持現存配電(dian)(dian)(dian)網(wang)的(de)(de)經濟運行(xing)，或者同時滿(man)足這兩個方面的(de)(de)要求。

　　分(fen)布式光伏發電(dian)(dian)(dian)(dian)(dian)系統的基本設(she)備(bei)包括光伏電(dian)(dian)(dian)(dian)(dian)池組件(jian)、光伏方陣支(zhi)架(jia)、直流(liu)(liu)匯(hui)流(liu)(liu)箱、直流(liu)(liu)配電(dian)(dian)(dian)(dian)(dian)柜、并(bing)網(wang)逆(ni)(ni)變(bian)器(qi)(qi)、交流(liu)(liu)配電(dian)(dian)(dian)(dian)(dian)柜等(deng)設(she)備(bei)，另外還有(you)供電(dian)(dian)(dian)(dian)(dian)系統監控裝(zhuang)置和環境(jing)監測裝(zhuang)置。其運行模式是(shi)在有(you)太(tai)陽輻射的條件(jian)下，光伏發電(dian)(dian)(dian)(dian)(dian)系統的太(tai)陽能(neng)電(dian)(dian)(dian)(dian)(dian)池組件(jian)陣列將太(tai)陽能(neng)轉換輸出的電(dian)(dian)(dian)(dian)(dian)能(neng)，經(jing)過(guo)直流(liu)(liu)匯(hui)流(liu)(liu)箱集(ji)中送入直流(liu)(liu)配電(dian)(dian)(dian)(dian)(dian)柜，由并(bing)網(wang)逆(ni)(ni)變(bian)器(qi)(qi)逆(ni)(ni)變(bian)成交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)供給建(jian)筑自身負(fu)載，多余(yu)或不足的電(dian)(dian)(dian)(dian)(dian)力通過(guo)聯(lian)接電(dian)(dian)(dian)(dian)(dian)網(wang)來(lai)調節。
