山東(dong)省(sheng)青州市魯東(dong)機械2.1MW光(guang)伏發(fa)電(dian)(dian)站(zhan)項目。彩鋼瓦屋(wu)頂光(guang)伏發(fa)電(dian)(dian)站(zhan)，已并網發(fa)電(dian)(dian)成功！

輸送方式

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

獨立光伏發電

獨立光伏(fu)發電(dian)(dian)系(xi)統(tong)也叫離網光伏(fu)發電(dian)(dian)系(xi)統(tong)。主要(yao)由(you)太陽能電(dian)(dian)池組(zu)件、控制器(qi)、蓄電(dian)(dian)池組(zu)成，若要(yao)為交流(liu)負載供電(dian)(dian)，還(huan)需要(yao)配置交流(liu)逆變(bian)器(qi)。

并網光伏發電

并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)系(xi)統(tong)就是(shi)(shi)太(tai)陽能(neng)組件產生的直流電(dian)(dian)經過并(bing)網(wang)(wang)(wang)逆變器轉換成符(fu)合市電(dian)(dian)電(dian)(dian)網(wang)(wang)(wang)要求的交(jiao)流電(dian)(dian)之后直接(jie)接(jie)入公共電(dian)(dian)網(wang)(wang)(wang)。并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)系(xi)統(tong)有(you)集中式大(da)型并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)電(dian)(dian)站一般都是(shi)(shi)國家級電(dian)(dian)站，主要特點(dian)是(shi)(shi)將所發(fa)電(dian)(dian)能(neng)直接(jie)輸送到電(dian)(dian)網(wang)(wang)(wang)，由電(dian)(dian)網(wang)(wang)(wang)統(tong)一調配向用戶供電(dian)(dian)。但(dan)這種電(dian)(dian)站投資(zi)大(da)、建設周期長(chang)、占地面積(ji)(ji)大(da)，發(fa)展(zhan)難(nan)度(du)相對較大(da)。而分散式小型并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)系(xi)統(tong)，特別是(shi)(shi)光(guang)(guang)伏(fu)(fu)建筑(zhu)一體化(hua)發(fa)電(dian)(dian)系(xi)統(tong)，由于投資(zi)小、建設快、占地面積(ji)(ji)小、政(zheng)策支持力(li)度(du)大(da)等優點(dian)，是(shi)(shi)并(bing)網(wang)(wang)(wang)光(guang)(guang)伏(fu)(fu)發(fa)電(dian)(dian)的主流。

分布式光伏發電

分布(bu)式光(guang)伏發(fa)電(dian)系統，又(you)稱分散(san)式發(fa)電(dian)或分布(bu)式供能，是指在用戶(hu)(hu)現場或靠近用電(dian)現場配置較(jiao)小的(de)光(guang)伏發(fa)電(dian)供電(dian)系統，以滿(man)足(zu)特定用戶(hu)(hu)的(de)需求(qiu)，支持現存配電(dian)網的(de)經(jing)濟運行(xing)，或者同時滿(man)足(zu)這兩個(ge)方面(mian)的(de)要求(qiu)。

　　分布式(shi)光(guang)伏(fu)發電系統(tong)(tong)的(de)基本設備包括光(guang)伏(fu)電池(chi)組件、光(guang)伏(fu)方(fang)陣支架、直(zhi)流(liu)(liu)(liu)(liu)匯流(liu)(liu)(liu)(liu)箱、直(zhi)流(liu)(liu)(liu)(liu)配(pei)電柜、并網(wang)逆(ni)變(bian)器、交(jiao)流(liu)(liu)(liu)(liu)配(pei)電柜等設備，另外(wai)還有供(gong)電系統(tong)(tong)監控裝置和環境監測裝置。其運(yun)行模式(shi)是在(zai)有太陽輻(fu)射的(de)條件下，光(guang)伏(fu)發電系統(tong)(tong)的(de)太陽能電池(chi)組件陣列將(jiang)太陽能轉換輸出的(de)電能，經過(guo)直(zhi)流(liu)(liu)(liu)(liu)匯流(liu)(liu)(liu)(liu)箱集中送(song)入直(zhi)流(liu)(liu)(liu)(liu)配(pei)電柜，由(you)并網(wang)逆(ni)變(bian)器逆(ni)變(bian)成交(jiao)流(liu)(liu)(liu)(liu)電供(gong)給建筑自(zi)身負(fu)載，多余(yu)或不足(zu)的(de)電力通過(guo)聯接電網(wang)來調節。
