山東省青州市魯東機械2.1MW光(guang)伏發(fa)(fa)電站項目(mu)。彩鋼瓦(wa)屋頂光(guang)伏發(fa)(fa)電站，已并(bing)網發(fa)(fa)電成功(gong)！

輸送方式

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

獨立光伏發電

獨立光(guang)伏發電(dian)系統也叫離網光(guang)伏發電(dian)系統。主要由太陽能電(dian)池組件、控(kong)制器、蓄(xu)電(dian)池組成，若要為交流負載供(gong)電(dian)，還需要配置交流逆變(bian)器。

并網光伏發電

并網(wang)光伏(fu)(fu)(fu)發(fa)(fa)(fa)電(dian)系統(tong)就(jiu)是(shi)(shi)太陽能組(zu)件(jian)產生的(de)直流電(dian)經過并網(wang)逆變器轉換成(cheng)符合市(shi)電(dian)電(dian)網(wang)要求的(de)交流電(dian)之后直接(jie)接(jie)入公共電(dian)網(wang)。并網(wang)光伏(fu)(fu)(fu)發(fa)(fa)(fa)電(dian)系統(tong)有(you)集中式大(da)(da)型(xing)(xing)并網(wang)光伏(fu)(fu)(fu)電(dian)站一般都是(shi)(shi)國(guo)家級(ji)電(dian)站，主要特點是(shi)(shi)將(jiang)所發(fa)(fa)(fa)電(dian)能直接(jie)輸送到(dao)電(dian)網(wang)，由電(dian)網(wang)統(tong)一調配向(xiang)用戶供電(dian)。但這種電(dian)站投(tou)資大(da)(da)、建(jian)(jian)設周期(qi)長、占地面積(ji)大(da)(da)，發(fa)(fa)(fa)展難度相對較(jiao)大(da)(da)。而分散式小型(xing)(xing)并網(wang)光伏(fu)(fu)(fu)系統(tong)，特別是(shi)(shi)光伏(fu)(fu)(fu)建(jian)(jian)筑(zhu)一體(ti)化(hua)發(fa)(fa)(fa)電(dian)系統(tong)，由于投(tou)資小、建(jian)(jian)設快、占地面積(ji)小、政策支(zhi)持力度大(da)(da)等優(you)點，是(shi)(shi)并網(wang)光伏(fu)(fu)(fu)發(fa)(fa)(fa)電(dian)的(de)主流。

分布式光伏發電

分布(bu)式(shi)光伏發(fa)(fa)(fa)電(dian)系統，又(you)稱分散(san)式(shi)發(fa)(fa)(fa)電(dian)或(huo)分布(bu)式(shi)供能，是指在(zai)用(yong)戶現(xian)(xian)場或(huo)靠近用(yong)電(dian)現(xian)(xian)場配置較小的(de)光伏發(fa)(fa)(fa)電(dian)供電(dian)系統，以滿足特定用(yong)戶的(de)需求，支持現(xian)(xian)存配電(dian)網的(de)經濟運行，或(huo)者同時滿足這兩個方面(mian)的(de)要求。

　　分布式光伏發(fa)電(dian)(dian)(dian)(dian)系統(tong)的(de)基本(ben)設(she)備包(bao)括光伏電(dian)(dian)(dian)(dian)池(chi)組件(jian)、光伏方(fang)陣支架、直(zhi)流匯(hui)流箱、直(zhi)流配電(dian)(dian)(dian)(dian)柜(ju)、并(bing)網(wang)逆變器、交(jiao)(jiao)流配電(dian)(dian)(dian)(dian)柜(ju)等(deng)設(she)備，另(ling)外還(huan)有供電(dian)(dian)(dian)(dian)系統(tong)監控裝置(zhi)和(he)環(huan)境監測裝置(zhi)。其運行模式是在(zai)有太陽輻射(she)的(de)條件(jian)下，光伏發(fa)電(dian)(dian)(dian)(dian)系統(tong)的(de)太陽能電(dian)(dian)(dian)(dian)池(chi)組件(jian)陣列將太陽能轉換輸出的(de)電(dian)(dian)(dian)(dian)能，經過(guo)直(zhi)流匯(hui)流箱集中送入直(zhi)流配電(dian)(dian)(dian)(dian)柜(ju)，由并(bing)網(wang)逆變器逆變成交(jiao)(jiao)流電(dian)(dian)(dian)(dian)供給建(jian)筑自(zi)身負載，多余或不(bu)足(zu)的(de)電(dian)(dian)(dian)(dian)力通(tong)過(guo)聯(lian)接電(dian)(dian)(dian)(dian)網(wang)來調節。
