山東省青(qing)州市魯東機械(xie)2.1MW光(guang)伏(fu)發電站項目。彩鋼瓦屋頂光(guang)伏(fu)發電站，已并網發電成功！

輸送方式

太陽能光(guang)伏(fu)(fu)發電分為獨立光(guang)伏(fu)(fu)發電、并(bing)網光(guang)伏(fu)(fu)發電、分布式光(guang)伏(fu)(fu)發電

獨立光伏發電

獨(du)立(li)光(guang)伏發(fa)電(dian)(dian)系(xi)統(tong)也叫離(li)網(wang)光(guang)伏發(fa)電(dian)(dian)系(xi)統(tong)。主(zhu)要(yao)(yao)由太陽(yang)能電(dian)(dian)池組(zu)件、控制器、蓄電(dian)(dian)池組(zu)成，若(ruo)要(yao)(yao)為交(jiao)(jiao)流負載(zai)供電(dian)(dian)，還需要(yao)(yao)配置交(jiao)(jiao)流逆變器。

并網光伏發電

并網(wang)(wang)光伏(fu)發電系統(tong)就是(shi)(shi)(shi)(shi)太陽能組件(jian)產(chan)生的(de)直流(liu)電經過(guo)并網(wang)(wang)逆變(bian)器(qi)轉(zhuan)換成符合市電電網(wang)(wang)要求的(de)交流(liu)電之后直接(jie)(jie)接(jie)(jie)入公共電網(wang)(wang)。并網(wang)(wang)光伏(fu)發電系統(tong)有集中(zhong)式(shi)大(da)型并網(wang)(wang)光伏(fu)電站(zhan)一般(ban)都是(shi)(shi)(shi)(shi)國家級電站(zhan)，主要特點是(shi)(shi)(shi)(shi)將(jiang)所發電能直接(jie)(jie)輸(shu)送到(dao)電網(wang)(wang)，由(you)電網(wang)(wang)統(tong)一調配向用戶供電。但這種電站(zhan)投資大(da)、建(jian)(jian)設周期長、占地面積(ji)大(da)，發展難(nan)度相(xiang)對較大(da)。而分散式(shi)小型并網(wang)(wang)光伏(fu)系統(tong)，特別(bie)是(shi)(shi)(shi)(shi)光伏(fu)建(jian)(jian)筑一體(ti)化發電系統(tong)，由(you)于投資小、建(jian)(jian)設快、占地面積(ji)小、政策(ce)支持(chi)力度大(da)等優點，是(shi)(shi)(shi)(shi)并網(wang)(wang)光伏(fu)發電的(de)主流(liu)。

分布式光伏發電

分布(bu)式光伏發電(dian)(dian)系統，又(you)稱(cheng)分散(san)式發電(dian)(dian)或(huo)分布(bu)式供能，是指在(zai)用(yong)(yong)戶(hu)(hu)現(xian)場或(huo)靠近(jin)用(yong)(yong)電(dian)(dian)現(xian)場配置較小(xiao)的(de)光伏發電(dian)(dian)供電(dian)(dian)系統，以滿足特定(ding)用(yong)(yong)戶(hu)(hu)的(de)需求(qiu)(qiu)，支持現(xian)存配電(dian)(dian)網的(de)經濟(ji)運行，或(huo)者同時滿足這兩個(ge)方面的(de)要求(qiu)(qiu)。

　　分布式光伏發(fa)電(dian)(dian)(dian)(dian)系統的(de)基本設備(bei)包括光伏電(dian)(dian)(dian)(dian)池(chi)組(zu)件(jian)、光伏方(fang)陣支(zhi)架(jia)、直(zhi)(zhi)流匯流箱、直(zhi)(zhi)流配電(dian)(dian)(dian)(dian)柜、并網逆(ni)變器、交流配電(dian)(dian)(dian)(dian)柜等設備(bei)，另(ling)外還有供電(dian)(dian)(dian)(dian)系統監控(kong)裝置(zhi)和環境監測裝置(zhi)。其運行模式是在有太陽輻(fu)射的(de)條件(jian)下，光伏發(fa)電(dian)(dian)(dian)(dian)系統的(de)太陽能電(dian)(dian)(dian)(dian)池(chi)組(zu)件(jian)陣列將(jiang)太陽能轉換(huan)輸出的(de)電(dian)(dian)(dian)(dian)能，經過直(zhi)(zhi)流匯流箱集中送(song)入直(zhi)(zhi)流配電(dian)(dian)(dian)(dian)柜，由(you)并網逆(ni)變器逆(ni)變成交流電(dian)(dian)(dian)(dian)供給建筑自身負(fu)載，多余或不足(zu)的(de)電(dian)(dian)(dian)(dian)力通(tong)過聯接電(dian)(dian)(dian)(dian)網來(lai)調(diao)節。
