輸送方式

太陽能(neng)光伏發電分(fen)(fen)為獨立光伏發電、并(bing)網光伏發電、分(fen)(fen)布式光伏發電

獨立光伏發電

獨立光(guang)伏發電系統也叫離網(wang)光(guang)伏發電系統。主(zhu)要(yao)由太陽能電池組件、控制器、蓄電池組成，若要(yao)為交(jiao)流負(fu)載(zai)供電，還需要(yao)配置交(jiao)流逆變器。

并網光伏發電

并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)(wang)(wang)光伏發電(dian)(dian)(dian)系統(tong)就是(shi)(shi)太陽(yang)能組件產生(sheng)的直流電(dian)(dian)(dian)經過并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)(wang)(wang)逆變(bian)器轉(zhuan)換成(cheng)符合市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)(wang)要求的交流電(dian)(dian)(dian)之(zhi)后(hou)直接(jie)(jie)接(jie)(jie)入公共電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)(wang)。并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)(wang)(wang)光伏發電(dian)(dian)(dian)系統(tong)有集中式(shi)(shi)大型(xing)并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)(wang)(wang)光伏電(dian)(dian)(dian)站一般都是(shi)(shi)國(guo)家級電(dian)(dian)(dian)站，主要特點是(shi)(shi)將(jiang)所發電(dian)(dian)(dian)能直接(jie)(jie)輸送到電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)(wang)，由(you)電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)(wang)(wang)統(tong)一調配(pei)向(xiang)用戶供電(dian)(dian)(dian)。但這(zhe)種電(dian)(dian)(dian)站投(tou)(tou)資(zi)大、建設周期(qi)長、占(zhan)(zhan)地面(mian)積大，發展(zhan)難度(du)相對(dui)較大。而分散式(shi)(shi)小(xiao)型(xing)并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)(wang)(wang)光伏系統(tong)，特別是(shi)(shi)光伏建筑(zhu)一體化發電(dian)(dian)(dian)系統(tong)，由(you)于投(tou)(tou)資(zi)小(xiao)、建設快、占(zhan)(zhan)地面(mian)積小(xiao)、政策支(zhi)持力(li)度(du)大等優點，是(shi)(shi)并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)(wang)(wang)光伏發電(dian)(dian)(dian)的主流。

分布式光伏發電

分(fen)布(bu)式(shi)(shi)光伏(fu)(fu)發(fa)電系(xi)統，又稱分(fen)散(san)式(shi)(shi)發(fa)電或(huo)分(fen)布(bu)式(shi)(shi)供能，是指在用(yong)戶現(xian)(xian)場或(huo)靠近用(yong)電現(xian)(xian)場配置較(jiao)小的(de)(de)光伏(fu)(fu)發(fa)電供電系(xi)統，以滿(man)足特(te)定用(yong)戶的(de)(de)需(xu)求，支持現(xian)(xian)存配電網的(de)(de)經濟運行(xing)，或(huo)者(zhe)同時滿(man)足這兩(liang)個(ge)方面的(de)(de)要求。

　　分(fen)布式光(guang)伏(fu)發電(dian)系(xi)統(tong)的(de)(de)基(ji)本設(she)備包括光(guang)伏(fu)電(dian)池(chi)組件(jian)、光(guang)伏(fu)方陣支架、直流匯流箱、直流配電(dian)柜(ju)、并(bing)網(wang)逆變器、交(jiao)流配電(dian)柜(ju)等設(she)備，另外還有(you)供電(dian)系(xi)統(tong)監(jian)控裝置和環境監(jian)測裝置。其(qi)運(yun)行模式是在有(you)太(tai)(tai)陽(yang)輻射的(de)(de)條件(jian)下(xia)，光(guang)伏(fu)發電(dian)系(xi)統(tong)的(de)(de)太(tai)(tai)陽(yang)能(neng)電(dian)池(chi)組件(jian)陣列將太(tai)(tai)陽(yang)能(neng)轉換(huan)輸出的(de)(de)電(dian)能(neng)，經過直流匯流箱集中(zhong)送(song)入直流配電(dian)柜(ju)，由并(bing)網(wang)逆變器逆變成交(jiao)流電(dian)供給建(jian)筑自(zi)身負載，多余或不足的(de)(de)電(dian)力通過聯接(jie)電(dian)網(wang)來調節。
