山東(dong)省青州市魯東(dong)機械2.1MW光(guang)伏(fu)發電(dian)站項目。彩(cai)鋼瓦屋頂光(guang)伏(fu)發電(dian)站，已并網發電(dian)成功！

輸送方式

太陽能(neng)光伏發電(dian)分(fen)(fen)為獨立光伏發電(dian)、并(bing)網(wang)光伏發電(dian)、分(fen)(fen)布式光伏發電(dian)

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(yao)由太陽(yang)能電池組件、控制器(qi)(qi)、蓄電池組成，若要(yao)為交(jiao)流負載供電，還需要(yao)配置(zhi)交(jiao)流逆變器(qi)(qi)。

并網光伏發電

并網(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)(fu)(fu)發(fa)(fa)電(dian)(dian)(dian)系統(tong)(tong)就是(shi)太陽能組件(jian)產生的(de)直流電(dian)(dian)(dian)經(jing)過并網(wang)(wang)(wang)逆變器(qi)轉換成符合市(shi)電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)(wang)要(yao)求的(de)交(jiao)流電(dian)(dian)(dian)之后直接(jie)接(jie)入公共電(dian)(dian)(dian)網(wang)(wang)(wang)。并網(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)(fu)(fu)發(fa)(fa)電(dian)(dian)(dian)系統(tong)(tong)有集中式大(da)型并網(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)(fu)(fu)電(dian)(dian)(dian)站一(yi)般都是(shi)國(guo)家級電(dian)(dian)(dian)站，主(zhu)要(yao)特(te)點是(shi)將所(suo)發(fa)(fa)電(dian)(dian)(dian)能直接(jie)輸送到(dao)電(dian)(dian)(dian)網(wang)(wang)(wang)，由電(dian)(dian)(dian)網(wang)(wang)(wang)統(tong)(tong)一(yi)調配向用戶供電(dian)(dian)(dian)。但這種電(dian)(dian)(dian)站投資大(da)、建(jian)(jian)(jian)設周期長、占地(di)面積(ji)大(da)，發(fa)(fa)展難度相對較大(da)。而(er)分散式小型并網(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)(fu)(fu)系統(tong)(tong)，特(te)別是(shi)光(guang)(guang)(guang)伏(fu)(fu)(fu)建(jian)(jian)(jian)筑一(yi)體化發(fa)(fa)電(dian)(dian)(dian)系統(tong)(tong)，由于投資小、建(jian)(jian)(jian)設快、占地(di)面積(ji)小、政(zheng)策支持(chi)力度大(da)等優點，是(shi)并網(wang)(wang)(wang)光(guang)(guang)(guang)伏(fu)(fu)(fu)發(fa)(fa)電(dian)(dian)(dian)的(de)主(zhu)流。

分布式光伏發電

分布式(shi)(shi)光伏發(fa)電(dian)(dian)(dian)系統，又稱分散式(shi)(shi)發(fa)電(dian)(dian)(dian)或(huo)分布式(shi)(shi)供能，是指在用戶現場或(huo)靠近用電(dian)(dian)(dian)現場配(pei)置較(jiao)小的光伏發(fa)電(dian)(dian)(dian)供電(dian)(dian)(dian)系統，以滿足(zu)特(te)定(ding)用戶的需求，支持現存配(pei)電(dian)(dian)(dian)網的經濟(ji)運行，或(huo)者(zhe)同時(shi)滿足(zu)這兩個(ge)方面(mian)的要求。

　　分布式(shi)光(guang)伏發電(dian)(dian)(dian)系(xi)統的(de)基本設備(bei)包括(kuo)光(guang)伏電(dian)(dian)(dian)池(chi)組(zu)件(jian)、光(guang)伏方陣支架、直(zhi)(zhi)流(liu)(liu)(liu)(liu)匯流(liu)(liu)(liu)(liu)箱、直(zhi)(zhi)流(liu)(liu)(liu)(liu)配(pei)電(dian)(dian)(dian)柜、并網(wang)逆(ni)變器、交流(liu)(liu)(liu)(liu)配(pei)電(dian)(dian)(dian)柜等設備(bei)，另(ling)外還有供電(dian)(dian)(dian)系(xi)統監(jian)控裝置(zhi)(zhi)和(he)環境監(jian)測(ce)裝置(zhi)(zhi)。其運行模式(shi)是在有太陽(yang)輻(fu)射的(de)條(tiao)件(jian)下，光(guang)伏發電(dian)(dian)(dian)系(xi)統的(de)太陽(yang)能(neng)電(dian)(dian)(dian)池(chi)組(zu)件(jian)陣列將太陽(yang)能(neng)轉(zhuan)換輸(shu)出的(de)電(dian)(dian)(dian)能(neng)，經過(guo)直(zhi)(zhi)流(liu)(liu)(liu)(liu)匯流(liu)(liu)(liu)(liu)箱集中(zhong)送(song)入直(zhi)(zhi)流(liu)(liu)(liu)(liu)配(pei)電(dian)(dian)(dian)柜，由并網(wang)逆(ni)變器逆(ni)變成交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)供給(gei)建筑自身負載，多余或不足的(de)電(dian)(dian)(dian)力通(tong)過(guo)聯接電(dian)(dian)(dian)網(wang)來(lai)調(diao)節(jie)。
