KuHybrid System, i-DC coupling kanye ne-AC coupling izindlela ezimbili zokuqala zokwakha zokuhlanganisa amamojula e-photovoltaic (PV), amabhethri okugcina amandla, nemithwalo noma igridi. Umehluko obalulekile usekutheni ugesi okhiqizwe amamojula e-PV ulethwa kubhethri ngendlela yamanje eqondile (DC) noma ifomu elishintshanayo lamanje (AC).
Ngezansi ukuqhathanisa okuningiliziwe kobuchwepheshe obubili:
1. Izimiso Eziyinhloko Nokugeleza Kwamandla
Ukuhlanganisa kwe-DC:
- Isimiso:
Ugesi we-DC okhiqizwe amamojula e-PV ufakwa kokokufaka kwe-DC yesistimu yokuguqula amandla (PCS) ngesilawuli se-PV (i-DC-DC converter). Lolu hlelo oludidiyelwe lwenza imisebenzi elandelayo:
- Iguqula ingxenye yamandla e-DC ibe yi-AC ukuze kulayishwe indawo noma kuthunyelwe igridi.
- Ishaja ibhethri ngokuqondile kusetshenziswa amandla e-DC (DC-to-DC).
- Ikhipha ibhethri ngokuguqula i-DC ibuyele ku-AC ukuze uthole ukulayisha noma umjovo wegridi.
- Ukugeleza kwamandla (Ukushaja):
Amamojula e-PV (DC) → Isilawuli se-PV → Ibhethri (DC)
(Indlela yokushaja eqondile ye-DC-to-DC)
- Ukugeleza kwamandla (Ukukhipha):
Ibhethri (DC) → PCS (DC-to-AC) → Layisha/Igridi (AC)
- Iphuzu elingukhiye:
Uma ushaja ibhethri, ugesi uhlala ukwifomu ye-DC kuyo yonke inqubo, ugwema ukuguqulwa okungadingekile.
I-AC Coupling:
- Isimiso:
Ugesi we-DC ovela kumamojula we-PV uqala ukuguqulwa ube yi-AC ngesiguquli se-PV esizinikele. La mandla e-AC angakwazi:
- Nikeza imithwalo yendawo ngokuqondile.
- Thumela kugridi.
Ukushaja ibhethri, amandla e-AC kufanele aguqulwe abuyele ku-DC yi-PCS (inverter yebhethri).
- Ukugeleza kwamandla (Ukushaja):
Amamojula e-PV (DC) → I-PV Inverter (DC-to-AC) → PCS (AC-to-DC) → Ibhethri (DC)
(Ifaka izinyathelo ezimbili zokuguqula: DC→AC→DC)
- Ukugeleza kwamandla (Ukukhipha):
Ibhethri (DC) → PCS (DC-to-AC) → Layisha/Igridi (AC)
- Iphuzu elingukhiye:
Ukushaja ibhethri kudinga umjikelezo ogcwele we-DC→AC→DC wokuguqula, wethula ukulahlekelwa okwengeziwe.
2. Isifinyezo Esiqhathanisayo Sezimpawu Ezisemqoka
Isiphetho
Kokubili ukuhlanganiswa kwe-DC ne-AC kunikeza izinzuzo ezihlukile kuye komongo wohlelo lokusebenza. I-DC coupling ihamba phambili ekusebenzeni kahle nasekusebenziseni izindleko zokufakwa okusha, okuyenza ilungele amaphrojekthi asendaweni eluhlaza agxile ekusebenzeni. Ukuhlanganisa i-AC, ngakolunye uhlangothi, kunikeza ukuguquguquka okukhulu nokuhambisana kwe-retrofit, okuyenza ibe yinketho ekhethwayo yokwengeza isitoreji kumasistimu akhona e-PV.
Ukukhetha okuhle kuncike ezicini ezithile eziqondene nephrojekthi—njengokuthi ingabe isistimu yintsha noma iyabuyiselwa, imikhawulo yesabelomali, okuhlosiwe okusebenzayo, izinhlelo zokunwetshwa zesikhathi esizayo, nokucatshangelwa kokuphepha. Njengoba ubuchwepheshe buthuthuka, zombili izakhiwo ziyaqhubeka nokuvela: Iziguquli ze-DC-coupled hybrid hybrid ziya zishintshashintsha futhi zibe namandla, kuyilapho amasistimu ahlanganiswe ne-AC ayathuthuka ngokokulawula kokuxhumana nokusebenza kahle kokuguqulwa.
Ngazise uma ungathanda inguqulo eyenzelwe izethameli ezithile (isb, abatshalizimali, onjiniyela, abenzi benqubomgomo) noma efomethwe okuthunyelwe kwe-carousel.
