山東省青州市魯東機械2.1MW光(guang)(guang)伏發電站項目(mu)。彩鋼瓦(wa)屋頂光(guang)(guang)伏發電站，已并網(wang)發電成功！

輸送方式

太(tai)陽能光(guang)伏(fu)(fu)發(fa)電分為獨立光(guang)伏(fu)(fu)發(fa)電、并網光(guang)伏(fu)(fu)發(fa)電、分布式光(guang)伏(fu)(fu)發(fa)電

獨立光伏發電

獨立光伏發電系(xi)統(tong)(tong)也(ye)叫離網光伏發電系(xi)統(tong)(tong)。主要(yao)由太陽能電池組件、控制(zhi)器、蓄電池組成，若要(yao)為交流負載供(gong)電，還需要(yao)配置(zhi)交流逆變(bian)器。

并網光伏發電

并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)系統就是(shi)太(tai)陽(yang)能(neng)組(zu)件產生的直(zhi)流(liu)電(dian)(dian)(dian)經過并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)逆變器轉換(huan)成符(fu)合市電(dian)(dian)(dian)電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)要求的交(jiao)流(liu)電(dian)(dian)(dian)之后直(zhi)接(jie)接(jie)入公共電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)。并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)系統有(you)集(ji)中(zhong)式大(da)型(xing)(xing)并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)光伏(fu)電(dian)(dian)(dian)站一般都是(shi)國家(jia)級電(dian)(dian)(dian)站，主(zhu)要特點(dian)是(shi)將所發(fa)電(dian)(dian)(dian)能(neng)直(zhi)接(jie)輸送到電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)，由電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)統一調配向用戶供電(dian)(dian)(dian)。但這種(zhong)電(dian)(dian)(dian)站投資(zi)大(da)、建(jian)設(she)周期長、占地面積大(da)，發(fa)展難(nan)度(du)相對較大(da)。而分散式小型(xing)(xing)并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)光伏(fu)系統，特別是(shi)光伏(fu)建(jian)筑一體化(hua)發(fa)電(dian)(dian)(dian)系統，由于投資(zi)小、建(jian)設(she)快、占地面積小、政策支持(chi)力度(du)大(da)等(deng)優點(dian)，是(shi)并(bing)(bing)(bing)網(wang)(wang)(wang)(wang)光伏(fu)發(fa)電(dian)(dian)(dian)的主(zhu)流(liu)。

分布式光伏發電

分(fen)布式(shi)光伏發(fa)電(dian)系(xi)統，又稱分(fen)散式(shi)發(fa)電(dian)或分(fen)布式(shi)供能，是指(zhi)在用(yong)戶現場(chang)或靠近用(yong)電(dian)現場(chang)配置較小的(de)(de)(de)光伏發(fa)電(dian)供電(dian)系(xi)統，以滿足特定(ding)用(yong)戶的(de)(de)(de)需求(qiu)，支持現存配電(dian)網的(de)(de)(de)經濟(ji)運行(xing)，或者(zhe)同(tong)時滿足這兩(liang)個方面的(de)(de)(de)要求(qiu)。
