太陽能光伏發電系統的組成介紹

太(tai)陽(yang)能(neng)(neng)光(guang)伏發(fa)電(dian)(dian)(dian)(dian)系統(tong)是利用太(tai)陽(yang)能(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)的光(guang)伏效應，將太(tai)陽(yang)光(guang)輻射能(neng)(neng)直接轉換成電(dian)(dian)(dian)(dian)能(neng)(neng)的一種新型發(fa)電(dian)(dian)(dian)(dian)系統(tong)。一套基本的光(guang)伏發(fa)電(dian)(dian)(dian)(dian)系統(tong)一般是由太(tai)陽(yang)能(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)板、太(tai)陽(yang)能(neng)(neng)控制器、逆變(bian)器和蓄電(dian)(dian)(dian)(dian)池(chi)(組)構成。下面是各組成的簡單介紹：

太(tai)陽能(neng)(neng)電(dian)池板：太(tai)陽能(neng)(neng)電(dian)池板是(shi)太(tai)陽能(neng)(neng)光伏發電(dian)系統(tong)中(zhong)的(de)核心部分，其作用(yong)(yong)是(shi)將太(tai)陽能(neng)(neng)直接轉換成電(dian)能(neng)(neng)，供(gong)負載使(shi)用(yong)(yong)或(huo)存貯(zhu)于蓄電(dian)池內備用(yong)(yong)。

太(tai)陽能(neng)(neng)(neng)控(kong)制器(qi)：太(tai)陽能(neng)(neng)(neng)控(kong)制器(qi)的(de)(de)基本作(zuo)用是為(wei)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)提供最佳的(de)(de)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)壓(ya)，快速、平穩(wen)、高效的(de)(de)為(wei)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)充(chong)電(dian)(dian)(dian)(dian)，并在充(chong)電(dian)(dian)(dian)(dian)過(guo)(guo)程中減少損耗，盡量延(yan)長(chang)蓄(xu)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)使用壽命；同時保護蓄(xu)電(dian)(dian)(dian)(dian)池(chi)，避(bi)免(mian)過(guo)(guo)充(chong)電(dian)(dian)(dian)(dian)和(he)過(guo)(guo)放電(dian)(dian)(dian)(dian)現象的(de)(de)發生。如果用戶使用的(de)(de)是直(zhi)流負(fu)載，通過(guo)(guo)太(tai)陽能(neng)(neng)(neng)控(kong)制器(qi)可以為(wei)負(fu)載提供穩(wen)定的(de)(de)直(zhi)流電(dian)(dian)(dian)(dian)(由于天氣的(de)(de)原因，太(tai)陽電(dian)(dian)(dian)(dian)池(chi)方陣發出的(de)(de)直(zhi)流電(dian)(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)和(he)電(dian)(dian)(dian)(dian)流不是很穩(wen)定)。

逆(ni)變(bian)器(qi)：逆(ni)變(bian)器(qi)的(de)作用(yong)(yong)就是將太陽能(neng)電池(chi)陣列和蓄電池(chi)提(ti)供(gong)的(de)低壓直流(liu)電逆(ni)變(bian)成(cheng)220伏交流(liu)電，供(gong)給交流(liu)負(fu)載使用(yong)(yong)。

蓄電(dian)(dian)池(組)：蓄電(dian)(dian)池(組)的(de)作用是(shi)將太陽能(neng)陣(zhen)列(lie)發出的(de)直(zhi)流電(dian)(dian)直(zhi)接儲存起來，供負(fu)(fu)載使用。在光(guang)伏發電(dian)(dian)系統中(zhong)，蓄電(dian)(dian)池處于浮充放電(dian)(dian)狀態，當(dang)日(ri)照(zhao)量大時，除(chu)了供給負(fu)(fu)裁(cai)用電(dian)(dian)外，還對蓄電(dian)(dian)池充電(dian)(dian)；當(dang)日(ri)照(zhao)量小時，這部分儲存的(de)能(neng)量將逐步放出。
