輸送方式

太陽能光伏(fu)發(fa)(fa)電分(fen)為(wei)獨立光伏(fu)發(fa)(fa)電、并網光伏(fu)發(fa)(fa)電、分(fen)布式光伏(fu)發(fa)(fa)電

獨立光伏發電

獨(du)立光伏發(fa)電(dian)(dian)系統(tong)也叫離網光伏發(fa)電(dian)(dian)系統(tong)。主要由太(tai)陽能(neng)電(dian)(dian)池(chi)組件、控制器、蓄電(dian)(dian)池(chi)組成(cheng)，若(ruo)要為(wei)交(jiao)流負載供電(dian)(dian)，還需要配置交(jiao)流逆變(bian)器。

并網光伏發電

并(bing)網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)系(xi)統(tong)就是太陽能組件產(chan)生的(de)直(zhi)(zhi)流(liu)(liu)電(dian)(dian)(dian)經過并(bing)網(wang)逆(ni)變器轉(zhuan)換成符合市(shi)電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)要求的(de)交流(liu)(liu)電(dian)(dian)(dian)之(zhi)后直(zhi)(zhi)接接入公(gong)共電(dian)(dian)(dian)網(wang)。并(bing)網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)系(xi)統(tong)有集(ji)中式大(da)型并(bing)網(wang)光(guang)伏(fu)(fu)電(dian)(dian)(dian)站一(yi)(yi)般都(dou)是國(guo)家級電(dian)(dian)(dian)站，主(zhu)要特(te)點是將所發電(dian)(dian)(dian)能直(zhi)(zhi)接輸送到(dao)電(dian)(dian)(dian)網(wang)，由(you)電(dian)(dian)(dian)網(wang)統(tong)一(yi)(yi)調配向用戶供電(dian)(dian)(dian)。但這(zhe)種電(dian)(dian)(dian)站投資大(da)、建設(she)周期長(chang)、占地(di)面(mian)積大(da)，發展難度(du)(du)相對較大(da)。而分散式小(xiao)型并(bing)網(wang)光(guang)伏(fu)(fu)系(xi)統(tong)，特(te)別是光(guang)伏(fu)(fu)建筑一(yi)(yi)體化發電(dian)(dian)(dian)系(xi)統(tong)，由(you)于投資小(xiao)、建設(she)快、占地(di)面(mian)積小(xiao)、政策(ce)支持力(li)度(du)(du)大(da)等優點，是并(bing)網(wang)光(guang)伏(fu)(fu)發電(dian)(dian)(dian)的(de)主(zhu)流(liu)(liu)。

分布式光伏發電

分(fen)布(bu)式光伏(fu)發電(dian)(dian)系統，又(you)稱分(fen)散(san)式發電(dian)(dian)或分(fen)布(bu)式供能，是(shi)指在用戶(hu)現(xian)場或靠(kao)近用電(dian)(dian)現(xian)場配置較小的光伏(fu)發電(dian)(dian)供電(dian)(dian)系統，以滿足特定用戶(hu)的需求，支持現(xian)存配電(dian)(dian)網的經濟運行，或者同(tong)時滿足這兩(liang)個方面的要求。

　　分布式光(guang)伏(fu)發電(dian)(dian)(dian)系(xi)統(tong)的基(ji)本設(she)備包括(kuo)光(guang)伏(fu)電(dian)(dian)(dian)池(chi)組(zu)件、光(guang)伏(fu)方(fang)陣支架、直流(liu)匯(hui)流(liu)箱(xiang)、直流(liu)配(pei)(pei)電(dian)(dian)(dian)柜、并網(wang)(wang)逆變器(qi)、交流(liu)配(pei)(pei)電(dian)(dian)(dian)柜等(deng)設(she)備，另外還有供(gong)電(dian)(dian)(dian)系(xi)統(tong)監控裝(zhuang)(zhuang)置(zhi)和環境監測裝(zhuang)(zhuang)置(zhi)。其運(yun)行模式是(shi)在有太陽輻射的條件下(xia)，光(guang)伏(fu)發電(dian)(dian)(dian)系(xi)統(tong)的太陽能(neng)電(dian)(dian)(dian)池(chi)組(zu)件陣列將太陽能(neng)轉換輸出的電(dian)(dian)(dian)能(neng)，經過直流(liu)匯(hui)流(liu)箱(xiang)集中送入直流(liu)配(pei)(pei)電(dian)(dian)(dian)柜，由并網(wang)(wang)逆變器(qi)逆變成(cheng)交流(liu)電(dian)(dian)(dian)供(gong)給建筑自身負載，多余或不足的電(dian)(dian)(dian)力(li)通過聯接電(dian)(dian)(dian)網(wang)(wang)來調(diao)節。
