山東(dong)省(sheng)青(qing)州市魯東(dong)機械2.1MW光伏發(fa)電站(zhan)項(xiang)目。彩(cai)鋼瓦屋頂光伏發(fa)電站(zhan)，已并網(wang)發(fa)電成功！

輸送方式

太陽能(neng)光伏發(fa)電(dian)分為獨立光伏發(fa)電(dian)、并網光伏發(fa)電(dian)、分布式(shi)光伏發(fa)電(dian)

獨立光伏發電

獨立光(guang)伏發電系(xi)統(tong)也叫離網(wang)光(guang)伏發電系(xi)統(tong)。主要(yao)由太(tai)陽能電池組件、控制器(qi)、蓄電池組成，若要(yao)為交流負載供電，還需要(yao)配置交流逆(ni)變(bian)器(qi)。

并網光伏發電

并(bing)網(wang)光伏(fu)(fu)發電(dian)(dian)(dian)(dian)(dian)系統(tong)就是(shi)太陽能組(zu)件產生的直(zhi)(zhi)流電(dian)(dian)(dian)(dian)(dian)經過并(bing)網(wang)逆變器轉換成符合市電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)網(wang)要求的交(jiao)流電(dian)(dian)(dian)(dian)(dian)之后直(zhi)(zhi)接接入公共電(dian)(dian)(dian)(dian)(dian)網(wang)。并(bing)網(wang)光伏(fu)(fu)發電(dian)(dian)(dian)(dian)(dian)系統(tong)有集中式(shi)大(da)型并(bing)網(wang)光伏(fu)(fu)電(dian)(dian)(dian)(dian)(dian)站一般都(dou)是(shi)國家(jia)級電(dian)(dian)(dian)(dian)(dian)站，主要特點(dian)是(shi)將所發電(dian)(dian)(dian)(dian)(dian)能直(zhi)(zhi)接輸送到電(dian)(dian)(dian)(dian)(dian)網(wang)，由電(dian)(dian)(dian)(dian)(dian)網(wang)統(tong)一調配向用戶供電(dian)(dian)(dian)(dian)(dian)。但這(zhe)種電(dian)(dian)(dian)(dian)(dian)站投(tou)資(zi)大(da)、建(jian)(jian)設周(zhou)期長、占(zhan)地面積大(da)，發展難度(du)(du)相對較(jiao)大(da)。而分散式(shi)小型并(bing)網(wang)光伏(fu)(fu)系統(tong)，特別是(shi)光伏(fu)(fu)建(jian)(jian)筑(zhu)一體化發電(dian)(dian)(dian)(dian)(dian)系統(tong)，由于(yu)投(tou)資(zi)小、建(jian)(jian)設快(kuai)、占(zhan)地面積小、政策支持力度(du)(du)大(da)等(deng)優點(dian)，是(shi)并(bing)網(wang)光伏(fu)(fu)發電(dian)(dian)(dian)(dian)(dian)的主流。

分布式光伏發電

分布式(shi)(shi)光伏(fu)發(fa)電(dian)(dian)系統(tong)，又稱(cheng)分散式(shi)(shi)發(fa)電(dian)(dian)或(huo)分布式(shi)(shi)供能，是指在(zai)用(yong)(yong)戶現(xian)場或(huo)靠近(jin)用(yong)(yong)電(dian)(dian)現(xian)場配(pei)置較小的光伏(fu)發(fa)電(dian)(dian)供電(dian)(dian)系統(tong)，以滿(man)足特定用(yong)(yong)戶的需求，支持現(xian)存配(pei)電(dian)(dian)網的經濟(ji)運行(xing)，或(huo)者同(tong)時滿(man)足這兩(liang)個方(fang)面(mian)的要求。

　　分布式光伏發電(dian)(dian)(dian)系(xi)統的基本設(she)備(bei)包括(kuo)光伏電(dian)(dian)(dian)池(chi)組(zu)(zu)件、光伏方(fang)陣支架(jia)、直流(liu)(liu)(liu)匯流(liu)(liu)(liu)箱、直流(liu)(liu)(liu)配電(dian)(dian)(dian)柜(ju)(ju)(ju)、并(bing)(bing)網逆變(bian)器、交(jiao)流(liu)(liu)(liu)配電(dian)(dian)(dian)柜(ju)(ju)(ju)等設(she)備(bei)，另外還有(you)供(gong)電(dian)(dian)(dian)系(xi)統監控裝(zhuang)置和環境監測(ce)裝(zhuang)置。其運行(xing)模式是(shi)在有(you)太(tai)(tai)陽輻(fu)射(she)的條件下，光伏發電(dian)(dian)(dian)系(xi)統的太(tai)(tai)陽能電(dian)(dian)(dian)池(chi)組(zu)(zu)件陣列將太(tai)(tai)陽能轉換(huan)輸出的電(dian)(dian)(dian)能，經過直流(liu)(liu)(liu)匯流(liu)(liu)(liu)箱集中(zhong)送入(ru)直流(liu)(liu)(liu)配電(dian)(dian)(dian)柜(ju)(ju)(ju)，由(you)并(bing)(bing)網逆變(bian)器逆變(bian)成交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)供(gong)給建(jian)筑(zhu)自身負(fu)載，多余(yu)或不足的電(dian)(dian)(dian)力通過聯接(jie)電(dian)(dian)(dian)網來調節。
