Izingxenye zesistimu ye-photovoltaic
Izingxenye zesistimu ye-1.PV Uhlelo lwe-PV luqukethe izingxenye ezibalulekile ezilandelayo. Amamojula we-Photovoltaic akhiqizwa kusuka kumaseli e-photovoltaic abe ngamaphaneli efilimu amancane abekwe phakathi kwesendlalelo se-encapsulation. I-Inverter iwukubuyisela emuva amandla e-DC akhiqizwe imojuli ye-PV ibe amandla e-AC axhunywe kugridi. Ibhethri iyisisetshenziswa esigcina ngokwekhemikhali amandla wamanje (DC). Ukukhweza kwe-Photovoltaic kunikeza ukusekelwa kokubeka amamojula we-PV.
2. Izinhlobo zezinhlelo ze-PV zingahlukaniswa kabanzi zibe izinhlobo ezimbili. Uhlelo oluxhunywe kwigridi: inzuzo yalolu hlobo lwesistimu ukuthi akukho sitoreji sebhethri, esixhunywe ngokuqondile kugridi kazwelonke, akudingeki ukhathazeke ngokunqamuka kwamandla; i-off-grid system: i-off-grid system idinga ibhethri ukuze igcine amandla, ngakho izindleko zizoba phezulu.
Izibonelo zamasistimu axhunywe kugridi namasistimu angaphandle kwegridi ayaboniswa uma kuqhathaniswa:
Izintambo zesistimu ye-Photovoltaic:
1. Amamojula we-PV ochungechunge-parallel uxhumano lwe-PV angaxhunywa ngokuhambisana noma ngochungechunge ngokuya ngezidingo, futhi angaxhunywa kungxube yochungechunge-parallel. Isibonelo, amamojula angu-4 12V PV asetshenziselwa ukuklama isistimu ye-off-grid engu-24V: amamojula angu-16 34V PV asetshenziselwa ukuklama isistimu exhunywe kugridi ehlanganisa izingxenye ezimbili zochungechunge.
2. Izingxenye zokuxhuma zamamodeli we-inverter. Inani lezingxenye ezingabhangqwa kumamodeli ahlukahlukene we-inverters liqinisekile, futhi inani lokuxhumeka kweqembu ngalinye lezingxenye lingabiwa ngokuya ngenani lamagatsha e-inverter, njengoba kuboniswe esithombeni:
3. Indlela yokuxhuma i-inverter ye-DC circuit breaker kanye ne-AC circuit breaker kufanele ifakwe kokokufaka kwe-DC kanye nokuphuma kwe-AC kwe-inverter ngokulandelanayo. Uma kuneqembu elingaphezu kwelilodwa lama-inverters okufanele axhunywe ngesikhathi esifanayo, i-terminal ye-DC yeqembu ngalinye lama-inverters kufanele ixhunywe kumojula ngokwehlukana, futhi i-terminal ye-AC ingaxhunywa kugridi ngokuhambisana, futhi ububanzi bekhebula kufanele buqiniswe ngokufanele.
4. Uxhumo lwegridi yesiphetho se-AC ngokuvamile luxhunywa kugridi yinkampani ephakela amandla, iyunithi yokufaka idinga kuphela ukugcina itheminali ye-AC ebhokisini lamamitha, futhi ifake iswishi yokunqamula. Uma umnikazi engasebenzisi igridi noma engakagunyazwa ukuthi axhumeke kugridi. Bese iyunithi yokufaka idinga ukuxhuma isiphetho se-AC ekugcineni okungezansi kweswishi yokungena kwamandla. Umsebenzisi uzodinga inverter enezigaba ezintathu uma exhunywe kumandla wezigaba ezintathu.
Ingxenye yebakaki:
Ubakaki bakasimende ophahleni oluyisicaba usimende ophahleni oluyisicaba lungahlukaniswa izingxenye ezimbili, enye iyingxenye eyisisekelo yebakaki kanti enye ingxenye yebakaki. Isisekelo sobakaki senziwe ngokhonkolo nge-C30 ejwayelekile. Abakaki abakhiqizwa abakhiqizi abahlukene bahlukile, futhi amabakaki asebenzayo ahlukile ngokuvumelana nezimo eziyingqayizivele zesayithi. Okokuqala, kulula ukuqonda izinto ezivamile zamabakaki kanye nokuma kwengxenye ngayinye ukuze kufakwe abakaki ngokushesha.
