Lub PV system muab faib ua tsib hom:
1. Siv tus kheej, lub zog seem ntawm lub grid
2. Siv tus kheej, lub zog seem tawm ntawm lub grid
3. Tag nrho daim phiaj
4. Tawm ntawm daim phiaj thiab On / off-grid
5. Siv tus kheej, lub zog ntxiv rau lub gird
Siv tus kheej, lub zog seem ntawm lub grid
Tus qauv photovoltaic system no yog qhov feem ntau, feem ntau yog lub zog photovoltaic faib tawm feem ntau siv hauv tus qauv no.
Cov hluav taws xob uas tsim los ntawm lub tshuab photovoltaic tuaj yeem siv ua ntej kom tau raws li nws lub nra hnyav, thiab cov seem tuaj yeem muag rau lub tuam txhab grid kom tsis txhob nkim nws; yog tias lub zog photovoltaic tsim tsis txaus, lub grid yuav muab nws. Txawm li cas los xij, hom kev nkag mus no yuav tsum tau sib tham nrog lub tuam txhab grid kom tau txais cov ntawv cog lus muag hluav taws xob zoo, xav txog cov txiaj ntsig ntawm ob tog. Cov tuam txhab grid muab ob txoj kev ntsuas ntse los ntsuas lub peev xwm tsim hluav taws xob ntawm cov nroj tsuag photovoltaic thiab kev siv hluav taws xob ntawm cov neeg siv khoom, thiab them lossis sau cov nqi hluav taws xob raws li cov cai thiab cov nqi sib tham.
Qhov tsis zoo tshaj plaws ntawm tus qauv no yog tias nws cov qauv nyiaj tau los tsis tuaj yeem kho tau, qhov sib piv ntawm kev siv tus kheej thiab lub zog seem rau lub grid yeej ib txwm hloov pauv, thiab tus nqi kwv yees ntawm cov nroj tsuag thaum nws tau txais nyiaj txiag thiab muag yuav qis dua qhov tseeb, txawm tias cov thawj coj tsis tuaj yeem tau txais tus nqi khoom tsim nyog vim lawv txhawj xeeb txog kev ua haujlwm yav tom ntej ntawm cov neeg siv.
Siv tus kheej, lub zog seem tawm ntawm lub grid
Qhov tshwj xeeb ntawm txoj kev siv tus kheej txuas nrog grid yog "Grid-connected tsis muaj internet". Lub chaw nkag ntawm hom no yog nyob rau ntawm qhov kawg qis ntawm lub tuam txhab grid meter thiab yog sab ntiag tug ntawm qhov chaw faib khoom tag nrho. Hauv kev xav, lub tuam txhab grid yuav tsis cuam tshuam rau kev nkag mus rau lub kaw lus, tab sis tus qauv no xav tau tias lub zog photovoltaic tsis tuaj yeem xa mus rau lub grid, yog li yuav tsum muaj lub cuab yeej tiv thaiv tam sim no. Thaum lub zog tsim los ntawm lub Hoobkas photovoltaic tshaj nws qhov load, lub cuab yeej tiv thaiv tam sim no yuav tsum pub lub teeb liab rov qab mus rau lub inverter, uas yuav txo qhov muaj peev xwm raws li qhov load, kom ua tau raws li qhov xav tau load thiab tsis xa hluav taws xob mus rau lub grid, kom ua tiav lub luag haujlwm ntawm lub photovoltaic system los tiv thaiv qhov counter-current.
Tus qauv photovoltaic system no feem ntau siv rau hauv cov xwm txheej ntawm kev siv hluav taws xob ntau ntawm tus neeg siv, kev siv hluav taws xob tas mus li, me ntsis lossis tsis muaj kev kaw lossis ib nrab kaw thaum lub xyoo, lossis txawm tias thaum lub caij so, tus neeg siv lub zog kho hluav taws xob kuj loj txaus los nqus feem ntau ntawm cov hluav taws xob uas tsim los ntawm PV system. Raws li qhov ua tau, lub zog tsim los ntawm PV system yuav raug siv tag yam tsis ua rau muaj kev pov tseg.
Tag nrho cov kab sib chaws
Hauv hom kev sib txuas ntawm lub grid no, qhov AC tso zis ntawm lub PV system txuas ncaj qha rau sab qis-voltage lossis sab siab-voltage ntawm lub grid, uas yog, sab grid ntawm ciam teb vaj tse. Ua li no, cov hluav taws xob tsim los ntawm lub system raug muag ncaj qha rau lub tuam txhab grid, thiab tus nqi muag feem ntau yog tus nqi pub dawb hauv zos, thaum tus nqi hluav taws xob ntawm tus neeg siv tseem tsis hloov pauv, qhov no hu ua "Ob kab ntawm cov nyiaj tau los thiab cov nuj nqis, txhua tus suav rau nws tus kheej tus account".
Kev muag khoom ncaj qha los ntawm grid-to-grid kuj yog qhov tseem ceeb ntawm cov ntawv thov PV; cov tub ua lag luam nyiam tus qauv vim nws yooj yim thiab txhim khu kev qha.
Tawm ntawm daim phiaj thiab On/off-grid
Tus qauv tawm ntawm lub grid no, tseem hu ua cov chaw tsim hluav taws xob photovoltaic (PV) sawv ntsug, yog ib lub kaw lus uas ua haujlwm ywj pheej ntawm lub grid thiab siv dav vim nws tsis txwv thaj chaw, tsuav yog muaj lub hnub ci tuaj yeem ntsia thiab siv, nws tsim nyog heev rau thaj chaw deb uas tsis muaj lub grid fais fab, cov kob cais tawm, cov nkoj nuv ntses, cov chaw yug tsiaj sab nraum zoov, thiab lwm yam. Nws kuj tseem siv tau ua cov khoom siv hluav taws xob thaum muaj xwm txheej ceev hauv cov chaw uas muaj hluav taws xob tsis tu ncua.
Tiam sis hom kev tsim hluav taws xob no yuav tsum muaj roj teeb, thiab tus nqi ntawm lub tshuab tsim hluav taws xob kim heev. Thiab lub roj teeb lub neej ntev, qhov xav tau kev hloov pauv, ua rau tus nqi siv nce siab. Yog li ntawd, kev lag luam nyuaj rau siv dav, yog li tsis pom zoo kom siv hluav taws xob rau qhov chaw yooj yim.
Nws kuj tseem siv tau zoo heev rau cov tsev neeg nyob rau thaj chaw uas tsis muaj hluav taws xob lossis qhov chaw uas muaj hluav taws xob txiav ntau zaus. Tshwj xeeb, nws tsuas yog siv los daws teeb meem teeb pom kev thaum tsaus ntuj xwb. Yog li ntawd, cov tshuab tsim hluav taws xob tawm ntawm lub network yog tsim tshwj xeeb rau kev siv hauv thaj chaw tawm ntawm lub network lossis hauv thaj chaw uas muaj hluav taws xob txiav ntau zaus.
Cov teeb pom kev zoo photovoltaic, cov teeb vaj thiab lwm yam khoom siv photovoltaic, kuj yog lub kaw lus photovoltaic off-grid.
Siv tus kheej, lub zog ntxiv rau lub gird
Cov xwm txheej ntawm daim ntawv thov ntawm hom kev sib xyaw ua ke / tawm ntawm daim phiaj no yog qhov hluav taws xob tsis tu ncua, lossis tus nqi siv tus kheej kim dua li tus nqi ntawm daim phiaj, thiab tus nqi siab tshaj plaws kim dua li tus nqi qis.
Qhov no yog siv lub zog photovoltaic los thauj khoom, tuaj yeem teeb tsa ntawm tus nqi siab tshaj plaws, txo tus nqi hluav taws xob; qhov thib ob, tuaj yeem them ntawm lub hav, tso tawm siab tshaj plaws, siv qhov sib txawv ntawm tus nqi siab tshaj plaws thiab hav kom tau nyiaj; qhov thib peb, thaum lub grid yog lub zog hluav taws xob ib txwm muaj, lub kaw lus ua haujlwm ua lub kaw lus txuas nrog lub grid ib txwm muaj, qhov twg lub zog photovoltaic raug pub rau lub load ua ntej, thiab lub zog ntau dhau raug khaws cia rau hauv roj teeb lossis muag rau lub grid, lub inverter tuaj yeem hloov mus rau hom off-grid, lub kaw lus txuas ntxiv ua lub zog thaub qab, lub zog photovoltaic thiab roj teeb rau lub load tseem ceeb los ntawm lub inverter, tsis muaj pov tseg.
Hom On/off-grid thiab hom off-grid yog tib yam kev xav tau ntawm cov roj teeb, tus nqi pib ntawm kev nqis peev yog qhov loj heev.
Hom kev nkag mus no yuav tsum tau sib tham nrog lub tuam txhab fais fab hauv daim ntawv cog lus muag fais fab, xav txog qhov txiaj ntsig ntawm ob tog.
Feem ntau, feem ntau yuav siv hom kev sib txuas ntawm lub grid; xaiv qhov twg, raws li qhov xav tau tshwj xeeb ntawm qhov project.
