山(shan)東省青州市魯東機械2.1MW光伏發(fa)電(dian)站(zhan)項目。彩鋼(gang)瓦屋頂光伏發(fa)電(dian)站(zhan)，已并(bing)網(wang)發(fa)電(dian)成功！

輸送方式

太陽(yang)能光(guang)伏(fu)發電(dian)(dian)分(fen)為(wei)獨立光(guang)伏(fu)發電(dian)(dian)、并網光(guang)伏(fu)發電(dian)(dian)、分(fen)布式(shi)光(guang)伏(fu)發電(dian)(dian)

獨立光伏發電

獨(du)立光(guang)伏(fu)發電(dian)(dian)系統也叫離網(wang)光(guang)伏(fu)發電(dian)(dian)系統。主(zhu)要(yao)由太陽能電(dian)(dian)池組件、控制器(qi)、蓄電(dian)(dian)池組成，若(ruo)要(yao)為交流(liu)(liu)負載供電(dian)(dian)，還需要(yao)配(pei)置交流(liu)(liu)逆變器(qi)。

并網光伏發電

并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)就是太陽能(neng)組件產生(sheng)的直流電(dian)(dian)(dian)(dian)(dian)經過(guo)并(bing)網(wang)(wang)(wang)逆變(bian)器轉換成(cheng)符合(he)市電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)要求的交(jiao)流電(dian)(dian)(dian)(dian)(dian)之(zhi)后(hou)直接接入(ru)公共電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)。并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)有集(ji)中式大(da)型并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)站一般都是國家級電(dian)(dian)(dian)(dian)(dian)站，主要特點(dian)是將所發(fa)電(dian)(dian)(dian)(dian)(dian)能(neng)直接輸(shu)送到電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)，由電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)統(tong)一調配向用戶(hu)供電(dian)(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)(dian)站投(tou)資(zi)大(da)、建(jian)設周期長、占(zhan)(zhan)地面積大(da)，發(fa)展難度相對(dui)較大(da)。而分散式小型并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)系(xi)統(tong)，特別(bie)是光(guang)(guang)伏(fu)(fu)(fu)建(jian)筑一體化發(fa)電(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)，由于投(tou)資(zi)小、建(jian)設快(kuai)、占(zhan)(zhan)地面積小、政策支持力度大(da)等優(you)點(dian)，是并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)(fu)發(fa)電(dian)(dian)(dian)(dian)(dian)的主流。

分布式光伏發電

分(fen)布式(shi)光伏(fu)發電(dian)(dian)(dian)系統，又稱(cheng)分(fen)散式(shi)發電(dian)(dian)(dian)或(huo)分(fen)布式(shi)供能(neng)，是指在(zai)用(yong)(yong)戶現場或(huo)靠近用(yong)(yong)電(dian)(dian)(dian)現場配(pei)置較小的(de)光伏(fu)發電(dian)(dian)(dian)供電(dian)(dian)(dian)系統，以滿足(zu)特(te)定用(yong)(yong)戶的(de)需求，支(zhi)持現存配(pei)電(dian)(dian)(dian)網的(de)經濟運行(xing)，或(huo)者同時滿足(zu)這兩個方面(mian)的(de)要求。

　　分布式(shi)光伏(fu)發(fa)電(dian)(dian)(dian)系統(tong)的(de)(de)基本設備包括光伏(fu)電(dian)(dian)(dian)池組件(jian)、光伏(fu)方陣(zhen)支(zhi)架、直(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱、直(zhi)流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)、并(bing)網(wang)逆(ni)變(bian)器、交流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)等設備，另外還(huan)有供(gong)電(dian)(dian)(dian)系統(tong)監控裝(zhuang)置和(he)環境監測裝(zhuang)置。其運行模式(shi)是在有太陽輻(fu)射的(de)(de)條件(jian)下，光伏(fu)發(fa)電(dian)(dian)(dian)系統(tong)的(de)(de)太陽能電(dian)(dian)(dian)池組件(jian)陣(zhen)列將太陽能轉換輸出的(de)(de)電(dian)(dian)(dian)能，經過(guo)(guo)直(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱集(ji)中(zhong)送(song)入直(zhi)流(liu)(liu)配(pei)電(dian)(dian)(dian)柜(ju)，由并(bing)網(wang)逆(ni)變(bian)器逆(ni)變(bian)成交流(liu)(liu)電(dian)(dian)(dian)供(gong)給(gei)建筑自身負載，多余或不足的(de)(de)電(dian)(dian)(dian)力通過(guo)(guo)聯(lian)接電(dian)(dian)(dian)網(wang)來調(diao)節。
