輸送方式

太陽能光(guang)伏發(fa)電分(fen)為(wei)獨立光(guang)伏發(fa)電、并(bing)網光(guang)伏發(fa)電、分(fen)布式光(guang)伏發(fa)電

獨立光伏發電

獨立光伏發電系統也叫離網光伏發電系統。主(zhu)要由太陽能電池組件、控制器(qi)、蓄(xu)電池組成，若(ruo)要為交(jiao)流(liu)負載供電，還(huan)需要配置交(jiao)流(liu)逆變器(qi)。

并網光伏發電

并(bing)網(wang)(wang)光(guang)(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)系統(tong)就是(shi)(shi)太陽能組件(jian)產生(sheng)的直(zhi)(zhi)流電(dian)(dian)(dian)(dian)經過并(bing)網(wang)(wang)逆變器轉換成(cheng)符(fu)合市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)(wang)要求的交流電(dian)(dian)(dian)(dian)之后直(zhi)(zhi)接(jie)接(jie)入(ru)公共電(dian)(dian)(dian)(dian)網(wang)(wang)。并(bing)網(wang)(wang)光(guang)(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)系統(tong)有集中式(shi)大(da)型(xing)并(bing)網(wang)(wang)光(guang)(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)站(zhan)一般(ban)都(dou)是(shi)(shi)國家級電(dian)(dian)(dian)(dian)站(zhan)，主要特點(dian)是(shi)(shi)將所發(fa)(fa)電(dian)(dian)(dian)(dian)能直(zhi)(zhi)接(jie)輸送到電(dian)(dian)(dian)(dian)網(wang)(wang)，由(you)電(dian)(dian)(dian)(dian)網(wang)(wang)統(tong)一調(diao)配向用戶(hu)供電(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)站(zhan)投資(zi)大(da)、建(jian)設(she)周期長、占(zhan)地面積大(da)，發(fa)(fa)展難度相對較大(da)。而分散式(shi)小(xiao)(xiao)型(xing)并(bing)網(wang)(wang)光(guang)(guang)(guang)伏(fu)系統(tong)，特別是(shi)(shi)光(guang)(guang)(guang)伏(fu)建(jian)筑一體(ti)化發(fa)(fa)電(dian)(dian)(dian)(dian)系統(tong)，由(you)于投資(zi)小(xiao)(xiao)、建(jian)設(she)快、占(zhan)地面積小(xiao)(xiao)、政策支(zhi)持(chi)力度大(da)等優(you)點(dian)，是(shi)(shi)并(bing)網(wang)(wang)光(guang)(guang)(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)(dian)的主流。

分布式光伏發電

分(fen)布式光伏(fu)發(fa)電(dian)系統，又稱分(fen)散(san)式發(fa)電(dian)或(huo)分(fen)布式供能(neng)，是(shi)指在(zai)用(yong)戶現(xian)場(chang)或(huo)靠(kao)近(jin)用(yong)電(dian)現(xian)場(chang)配置較小的光伏(fu)發(fa)電(dian)供電(dian)系統，以滿(man)足特定(ding)用(yong)戶的需求(qiu)，支持現(xian)存配電(dian)網的經濟(ji)運行，或(huo)者同時滿(man)足這兩個方面的要求(qiu)。

　　分布式(shi)光伏發(fa)電系(xi)統(tong)的(de)(de)基(ji)本設備包括(kuo)光伏電池組(zu)件(jian)、光伏方(fang)陣支架、直(zhi)流(liu)匯(hui)流(liu)箱(xiang)、直(zhi)流(liu)配(pei)電柜(ju)、并網逆變器、交(jiao)流(liu)配(pei)電柜(ju)等設備，另外還有(you)供電系(xi)統(tong)監控裝置和環境監測裝置。其運行模式(shi)是在有(you)太(tai)陽(yang)輻射的(de)(de)條件(jian)下(xia)，光伏發(fa)電系(xi)統(tong)的(de)(de)太(tai)陽(yang)能電池組(zu)件(jian)陣列將太(tai)陽(yang)能轉換輸出的(de)(de)電能，經過直(zhi)流(liu)匯(hui)流(liu)箱(xiang)集中送入直(zhi)流(liu)配(pei)電柜(ju)，由并網逆變器逆變成交(jiao)流(liu)電供給建筑自身負載，多余或不足的(de)(de)電力通過聯接電網來調節(jie)。
