Mu Hybrid System, DC coupling ndi AC coupling ndi njira ziwiri zoyambirira zopangira ma module a photovoltaic (PV), mabatire osungira mphamvu, ndi katundu kapena grid. Kusiyanitsa kwakukulu kuli ngati magetsi opangidwa ndi ma PV modules amaperekedwa ku batri mwachindunji (DC) kapena mawonekedwe amakono (AC).
Pansipa pali kufananitsa kwatsatanetsatane kwamatekinoloje awiriwa:
1. Mfundo Zazikulu ndi Kuyenda kwa Mphamvu
Kugwirizana kwa DC:
- Mfundo:
Magetsi a DC opangidwa ndi ma module a PV amalowetsedwa mumagetsi a DC amagetsi osinthira mphamvu (PCS) kudzera pa chowongolera cha PV (DC-DC converter). Integrated system imagwira ntchito izi:
- Imasintha gawo lina lamagetsi a DC kukhala AC kuti lizinyamula katundu wakomweko kapena kutumiza kunja kwa grid.
- Imayitanitsa batire mwachindunji pogwiritsa ntchito mphamvu ya DC (DC-to-DC).
- Imatulutsa batire potembenuza DC kukhala AC kuti ipereke katundu kapena jekeseni wa gridi.
- Kuyenda kwa Mphamvu (Kulipira):
PV Module (DC) → PV Controller → Battery (DC)
(Njira yopangira Direct DC-to-DC)
- Kuyenda kwa Mphamvu (Kutaya):
Batiri (DC) → PCS (DC-to-AC) → Load/Gridi (AC)
- Mfundo yofunika:
Mukamalipira batire, magetsi amakhalabe mu mawonekedwe a DC nthawi yonseyi, kupewa kutembenuka kosafunika.
Kuphatikiza kwa AC:
- Mfundo:
Magetsi a DC kuchokera ku ma module a PV amayamba kusinthidwa kukhala AC kudzera pa inverter yodzipereka ya PV. Mphamvu ya AC iyi imatha:
- Perekani katundu wamba mwachindunji.
- Kutumizidwa ku gululi.
Kuti mupereke batire, mphamvu ya AC iyenera kusinthidwa kukhala DC ndi PCS (inverter ya batri).
- Kuyenda kwa Mphamvu (Kulipira):
PV Module (DC) → PV Inverter (DC-to-AC) → PCS (AC-to-DC) → Battery (DC)
(Ikuphatikiza njira ziwiri zosinthira: DC→ AC→DC)
- Kuyenda kwa Mphamvu (Kutaya):
Batiri (DC) → PCS (DC-to-AC) → Load/Gridi (AC)
- Mfundo yofunika:
Kulipiritsa batire kumafuna kuzungulira kwathunthu kwa DC→AC→DC, kubweretsa zotayika zina.
2. Kufananiza Chidule cha Makhalidwe Ofunikira
Mapeto
Kulumikizana kwa DC ndi AC kumapereka maubwino apadera kutengera momwe akugwiritsira ntchito. Kuphatikizana kwa DC kumapambana pakuchita bwino komanso kutsika mtengo pakuyika kwatsopano, kupangitsa kuti ikhale yabwino pama projekiti a greenfield omwe amayang'ana kwambiri magwiridwe antchito. Kulumikizana kwa AC, kumbali ina, kumapereka kusinthasintha kwakukulu komanso kuyanjananso, ndikupangitsa kukhala chisankho chokondedwa chowonjezera zosungira kumakina omwe alipo kale a PV.
Chisankho chabwino kwambiri chimadalira zinthu zosiyanasiyana zokhudzana ndi projekiti-monga ngati dongosololi ndilatsopano kapena kubwezeretsanso, zovuta za bajeti, zolinga zogwirira ntchito, mapulani okulitsa mtsogolo, ndi malingaliro achitetezo. Pomwe ukadaulo ukupita patsogolo, zomanga zonse ziwirizi zikupitilirabe kusinthika: ma inverter ophatikizika a DC akukhala osinthika komanso amphamvu, pomwe makina ophatikizika a AC akuyenda bwino potsata kuwongolera ndi kutembenuka mtima.
Ndidziwitseni ngati mungafune mtundu wokomera anthu ena (monga, osunga ndalama, mainjiniya, opanga mfundo) kapena osinthidwa kuti agwirizane ndi ma carousel.
