山(shan)東(dong)省青州市魯東(dong)機械2.1MW光伏發(fa)電站項目。彩(cai)鋼瓦(wa)屋頂光伏發(fa)電站，已并網(wang)發(fa)電成功！

輸送方式

太陽能光伏(fu)發(fa)電(dian)分為獨立(li)光伏(fu)發(fa)電(dian)、并網光伏(fu)發(fa)電(dian)、分布式光伏(fu)發(fa)電(dian)

獨立光伏發電

獨立(li)光伏(fu)發(fa)電系(xi)統(tong)也叫離網光伏(fu)發(fa)電系(xi)統(tong)。主要(yao)由太陽(yang)能電池組(zu)件、控制器、蓄電池組(zu)成，若要(yao)為交流負(fu)載供電，還(huan)需要(yao)配置(zhi)交流逆變器。

并網光伏發電

并(bing)網光(guang)伏發(fa)電(dian)(dian)(dian)(dian)(dian)系統(tong)就是(shi)太(tai)陽能(neng)組件產生的直流電(dian)(dian)(dian)(dian)(dian)經過并(bing)網逆(ni)變(bian)器轉換成符(fu)合市電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)網要求的交流電(dian)(dian)(dian)(dian)(dian)之后(hou)直接(jie)接(jie)入(ru)公共(gong)電(dian)(dian)(dian)(dian)(dian)網。并(bing)網光(guang)伏發(fa)電(dian)(dian)(dian)(dian)(dian)系統(tong)有集中式(shi)大(da)型并(bing)網光(guang)伏電(dian)(dian)(dian)(dian)(dian)站一(yi)般都(dou)是(shi)國家級電(dian)(dian)(dian)(dian)(dian)站，主(zhu)要特(te)點(dian)是(shi)將所發(fa)電(dian)(dian)(dian)(dian)(dian)能(neng)直接(jie)輸送到電(dian)(dian)(dian)(dian)(dian)網，由(you)電(dian)(dian)(dian)(dian)(dian)網統(tong)一(yi)調配向用(yong)戶供電(dian)(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)(dian)站投(tou)資大(da)、建設(she)周期長、占(zhan)地面積大(da)，發(fa)展(zhan)難度(du)相對較大(da)。而分散式(shi)小型并(bing)網光(guang)伏系統(tong)，特(te)別是(shi)光(guang)伏建筑一(yi)體化發(fa)電(dian)(dian)(dian)(dian)(dian)系統(tong)，由(you)于(yu)投(tou)資小、建設(she)快、占(zhan)地面積小、政策支持力(li)度(du)大(da)等(deng)優點(dian)，是(shi)并(bing)網光(guang)伏發(fa)電(dian)(dian)(dian)(dian)(dian)的主(zhu)流。

分布式光伏發電

分布(bu)式(shi)光伏發電(dian)系(xi)統(tong)，又稱分散式(shi)發電(dian)或(huo)分布(bu)式(shi)供(gong)能，是指在用(yong)戶現(xian)場或(huo)靠近用(yong)電(dian)現(xian)場配置較小的光伏發電(dian)供(gong)電(dian)系(xi)統(tong)，以(yi)滿(man)足特定用(yong)戶的需求，支持(chi)現(xian)存配電(dian)網的經(jing)濟運行，或(huo)者(zhe)同時滿(man)足這兩個方(fang)面的要求。

　　分(fen)布式光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)(tong)的(de)基本設備包括(kuo)光(guang)伏(fu)電(dian)(dian)(dian)池組(zu)件、光(guang)伏(fu)方陣支架、直流(liu)匯流(liu)箱、直流(liu)配(pei)電(dian)(dian)(dian)柜(ju)、并網(wang)逆(ni)變(bian)器、交流(liu)配(pei)電(dian)(dian)(dian)柜(ju)等設備，另外還(huan)有供電(dian)(dian)(dian)系(xi)統(tong)(tong)監(jian)控裝(zhuang)置和環境(jing)監(jian)測(ce)裝(zhuang)置。其運(yun)行(xing)模式是在有太(tai)(tai)陽輻(fu)射的(de)條(tiao)件下，光(guang)伏(fu)發(fa)(fa)電(dian)(dian)(dian)系(xi)統(tong)(tong)的(de)太(tai)(tai)陽能電(dian)(dian)(dian)池組(zu)件陣列將(jiang)太(tai)(tai)陽能轉換輸出的(de)電(dian)(dian)(dian)能，經過直流(liu)匯流(liu)箱集中送入直流(liu)配(pei)電(dian)(dian)(dian)柜(ju)，由并網(wang)逆(ni)變(bian)器逆(ni)變(bian)成交流(liu)電(dian)(dian)(dian)供給(gei)建筑自(zi)身負載，多(duo)余或不足的(de)電(dian)(dian)(dian)力通過聯接(jie)電(dian)(dian)(dian)網(wang)來調節。
