Nidaamka Isku-dhafka ah, isku-xidhka DC iyo isku-xidhka AC ayaa ah labada hab ee aasaasiga ah ee qaab-dhismeedka isku-dhafka ah ee qaybaha sawirkavoltaic (PV), baytariyada kaydinta tamarta, iyo xamuulka ama shabaggadda. Farqiga aasaasiga ah wuxuu ku xiran yahay in korontadu ay abuuraan cutubyada PV in la geeyo batteriga si toos ah hadda (DC) ama qaabka beddelka hadda (AC).
Hoos waxaa ah isbarbardhigga tafatiran ee labada tignoolajiyada:
1. Mabaadi'da asaasiga ah iyo socodka tamarta
Isku-xidhka DC:
- Mabda'a:
Korontada DC ee ay abuuraan qaybaha PV waxaa lagu shubaa gelinta DC ee habka beddelka awoodda (PCS) iyada oo loo marayo kontaroolaha PV (beddelaha DC-DC). Nidaamkan isku dhafan wuxuu fuliyaa hawlaha soo socda:
- Wuxuu u beddelaa qayb ka mid ah awoodda DC AC ee xamuulka maxalliga ah ama dhoofinta xadhkaha.
- Si toos ah u dallaca batteriga adoo isticmaalaya awoodda DC (DC-to-DC).
- Wuxuu soo daayaa batteriga isagoo DC ugu beddelaya AC si loogu shubo sahayda ama duritaanka xadhkaha.
- Socodka tamarta (Dallacaadda):
PV Modules (DC) → Xakamaynta PV → Battery (DC)
(Dariiqa dallacaadda tooska ah ee DC-ilaa-DC)
- Qulqulka Tamarta (Soo dayn):
Battery (DC) → PCS (DC-to-AC) → Load/Grid (AC)
- Qodobka Muhiimka ah:
Marka batteriga lagu dallaco, korontadu waxay ahaanaysaa qaab DC inta ay socoto hawsha, iyadoo laga fogaanayo beddelaad aan loo baahnayn.
Isku-xidhka AC:
- Mabda'a:
Korontada DC ee qaybaha PV ayaa marka hore loo beddelaa AC iyada oo loo sii marayo beddele PV u go'an. Awoodda AC-gu waxay noqon kartaa:
- Si toos ah u bixi rarka gudaha.
- Lagu dhoofiyo shabkada.
Si aad u dalacdo batteriga, awoodda AC waa in PCS-gu dib ugu soo celiyaa DC.
- Socodka tamarta (Dallacaadda):
PV Modules (DC) → Inverter PV (DC-to-AC) → PCS (AC-to-DC) → Battery (DC)
(Waxay ku lug leedahay laba tilaabo beddelaad: DC→AC→DC)
- Qulqulka Tamarta (Soo dayn):
Battery (DC) → PCS (DC-to-AC) → Load/Grid (AC)
- Qodobka Muhiimka ah:
Ku dallaca batteriga wuxuu u baahan yahay wareeg beddelaad DC → AC → DC buuxa, oo soo bandhigaya khasaare dheeraad ah.
2. Isbarbardhigga Tilmaamaha Muhiimka ah oo kooban
Gabagabo
Labada isku dhafka DC iyo AC waxay bixiyaan faa'iidooyin kala duwan iyadoo ku xiran codsiga codsiga. Isku xirka DC wuxuu ka sarreeyaa hufnaanta iyo waxtarka kharashka ee rakibaadda cusub, taasoo ka dhigaysa mid ku habboon mashaariicda cagaaran ee diiradda saaraya waxqabadka. Isku xirka AC, dhanka kale, wuxuu bixiyaa dabacsanaan weyn iyo iswaafajin dib u habeyn, taasoo ka dhigaysa doorashada la doorbido in lagu daro kaydinta nidaamyada PV jira.
Doorashada ugu fiican waxay ku xiran tahay arrimo kala duwan oo mashruuc gaar ah - sida haddii nidaamku yahay mid cusub ama dib loo habeynayo, caqabadaha miisaaniyadda, bartilmaameedyada waxtarka leh, qorshooyinka ballaarinta mustaqbalka, iyo tixgelinnada badbaadada. Marka ay tignoolajiyadu horumarto, labada qaab-dhismeedku waxay sii wadaan inay horumaraan: beddelayaasha isku-dhafan ee DC-ku-xidhan waxay noqonayaan kuwo la taaban karo oo awood badan, halka nidaamyada AC-ku-xidhan ay horumarayaan marka la eego xakamaynta isku-duwidda iyo waxtarka beddelidda.
