光伏變頻恒壓供水設備的應用
太陽能(neng)(neng)光伏(fu)(fu)揚水(shui)(shui)系統(tong)(tong)(tong)(tong)主要(yao)由(you)三個部分組(zu)成(cheng)：太陽能(neng)(neng)電(dian)池組(zu)件、PDS33光伏(fu)(fu)揚水(shui)(shui)逆變(bian)(bian)器和三相交(jiao)流水(shui)(shui)泵。太陽能(neng)(neng)電(dian)池陣列由(you)多塊太陽能(neng)(neng)電(dian)池組(zu)件串并聯而成(cheng)，吸收日照輻射能(neng)(neng)量并將其轉(zhuan)化(hua)為電(dian)能(neng)(neng)，為整個系統(tong)(tong)(tong)(tong)提供動力(li)電(dian)源。光伏(fu)(fu)揚水(shui)(shui)逆變(bian)(bian)器對系統(tong)(tong)(tong)(tong)的運行(xing)實(shi)施控制(zhi)和調(diao)節，將太陽電(dian)池陣列發(fa)出(chu)的直(zhi)流電(dian)轉(zhuan)換為交(jiao)流電(dian)，驅(qu)動水(shui)(shui)泵，并根據日照強度(du)的變(bian)(bian)化(hua)實(shi)時地(di)調(diao)節輸出(chu)頻率(lv)，實(shi)現最大功率(lv)點跟蹤，最大限(xian)度(du)地(di)利(li)用太陽能(neng)(neng)。水(shui)(shui)泵由(you)三相交(jiao)流電(dian)機驅(qu)動，從深(shen)井中抽(chou)水(shui)(shui)，注(zhu)入蓄水(shui)(shui)箱/池或直(zhi)接接入灌溉系統(tong)(tong)(tong)(tong)。根據實(shi)際系統(tong)(tong)(tong)(tong)需求和安裝條件，可(ke)采用不同類型的水(shui)(shui)泵進行(xing)工作。
系統特點
光伏變頻恒壓供水設備的應用
1. 光(guang)伏發電系統(tong)全自動運行，無須人工值守；光(guang)伏揚(yang)水(shui)系統(tong)由太陽電池(chi)(chi)陣列、揚(yang)水(shui)逆變器及水(shui)泵構(gou)成，免去蓄(xu)電池(chi)(chi)之(zhi)類的儲(chu)能裝(zhuang)置，以蓄(xu)水(shui)替代(dai)蓄(xu)電,直接驅動水(shui)泵揚(yang)水(shui)，可靠性高(gao)，同(tong)時(shi)大幅降(jiang)低系統(tong)的建設和維護成本。
2. 采(cai)用PDS33光(guang)伏揚(yang)水(shui)逆變器(qi)，根(gen)據(ju)日(ri)(ri)照強度(du)的變化調節水(shui)泵轉(zhuan)(zhuan)速(su)，使輸出功率接近(jin)太陽電池陣列的最大(da)功率；當(dang)日(ri)(ri)照很(hen)充足(zu)時，保證(zheng)水(shui)泵的轉(zhuan)(zhuan)速(su)不(bu)超過額定轉(zhuan)(zhuan)速(su)；當(dang)日(ri)(ri)照不(bu)足(zu)時，根(gen)據(ju)設定最低(di)運行(xing)頻(pin)率是(shi)否(fou)滿足(zu)，否(fou)則自動停止(zhi)運行(xing)。
3. 水(shui)泵(beng)由三相(xiang)交流電機驅動，從深井(jing)中抽水(shui)，注入蓄水(shui)箱/池，或直接(jie)接(jie)入灌溉系(xi)統。根據實際系(xi)統需求(qiu)和安裝(zhuang)條件，可采用不同類型(xing)的水(shui)泵(beng)進行工作(zuo)。
4. 可以根據地(di)區、客戶不(bu)同需(xu)求提供經(jing)濟有(you)效的解決方案。
