摘要:光伏發電系統是根據光生伏特效應原理,利用太陽能電池將太陽光能直接轉化為電能的發電系統。它的主要部件是太陽能電池、蓄電池、控制器和逆變器。其特點是安全可靠、無噪聲、低污染、無須消耗燃料、能獨立發電又能并網運行。下面就來了解下光伏發電系統分類及應用領域。

一、光伏發電系統分類

光(guang)伏(fu)發電(dian)系統(tong)(tong)分為(wei)獨立光(guang)伏(fu)發電(dian)系統(tong)(tong)、并網光(guang)伏(fu)發電(dian)系統(tong)(tong)及分布式(shi)光(guang)伏(fu)發電(dian)系統(tong)(tong)。

1、獨立光伏發電系統

獨立光(guang)(guang)伏(fu)(fu)發電(dian)也叫離網光(guang)(guang)伏(fu)(fu)發電(dian)。主(zhu)要由太(tai)陽(yang)(yang)電(dian)池(chi)(chi)組(zu)件、控制(zhi)器(qi)、蓄(xu)電(dian)池(chi)(chi)組(zu)成,若(ruo)要為交流負載供電(dian),還需要配置交流逆變器(qi),獨立光(guang)(guang)伏(fu)(fu)電(dian)站包括邊遠地區(qu)的(de)村莊供電(dian)系統(tong)、太(tai)陽(yang)(yang)能(neng)戶用電(dian)源(yuan)(yuan)系統(tong)、通信(xin)信(xin)號電(dian)源(yuan)(yuan)、陰(yin)極(ji)保護、太(tai)陽(yang)(yang)能(neng)路燈等各(ge)種帶有蓄(xu)電(dian)池(chi)(chi)的(de)可以獨立運行(xing)的(de)光(guang)(guang)伏(fu)(fu)發電(dian)系統(tong)。

3、分布式光伏發電系統

分布式(shi)光(guang)伏(fu)(fu)發電(dian)(dian)系統(tong)又可分為集中(zhong)式(shi)大型并(bing)網(wang)(wang)光(guang)伏(fu)(fu)電(dian)(dian)站(zhan)和分布式(shi)光(guang)伏(fu)(fu)系統(tong)。集中(zhong)式(shi)大型并(bing)網(wang)(wang)光(guang)伏(fu)(fu)電(dian)(dian)站(zhan)的主(zhu)要特點是(shi)能將所發電(dian)(dian)直接(jie)輸送到電(dian)(dian)網(wang)(wang),由電(dian)(dian)網(wang)(wang)統(tong)一調配向用戶(hu)供(gong)電(dian)(dian)。這種(zhong)電(dian)(dian)站(zhan)投(tou)(tou)資(zi)大、建設周期(qi)長、占地(di)面積(ji)大。而(er)分布式(shi)光(guang)伏(fu)(fu)系統(tong),有投(tou)(tou)資(zi)小、建設快、占地(di)面積(ji)小、政策支持力度大等優點。
