Tsim Ntawm Off-Grid Photovoltaic Power Generation System
Off-grid photovoltaic power generation systems yog dav siv nyob rau hauv tej thaj chaw deb roob, cheeb tsam uas tsis yog hluav taws xob, Islands, kev sib txuas lus hauv paus chaw nres tsheb, thiab txoj kev teeb. Txawm yog nruab hnub lossis hmo ntuj, txawm tias tsis muaj kab sib txuas, nws tseem tuaj yeem muab cov khoom siv hluav taws xob ruaj khov rau txhua lub sijhawm kom tau raws li qhov xav tau ntawm lub zog thiab kev ua haujlwm ntawm cov neeg nyob hauv, tsev kawm ntawv, lossis cov chaw tsim khoom me me hauv cheeb tsam tsis muaj hluav taws xob, tsis muaj zog, thiab lub zog tsis ruaj khov.
Lub tshuab hluav taws xob photovoltaic off-grid hluav taws xob tau muab faib ua cov tshuab DC me me, nruab nrab-qhov loj me off-daim phiaj hluav taws xob tsim hluav taws xob, thiab cov tshuab hluav taws xob loj hauv hluav taws xob raws li qhov ntsuas. Lub DC me me yog qhov tseem ceeb los daws cov teeb pom kev zoo tshaj plaws thiab DC lub zog them nyiaj xav tau hauv thaj chaw tsis muaj hluav taws xob. Qhov nruab nrab-qhov loj me off-grid system yog tsuas yog los daws qhov kev thov hluav taws xob ntawm cov tsev neeg, tsev kawm ntawv, thiab cov chaw tsim khoom me. Lub tshuab hluav taws xob loj tshaj tawm hluav taws xob feem ntau daws qhov kev thov hluav taws xob ntawm tag nrho lub zos thiab tag nrho cov kob.
Lub hauv paus ntsiab lus ntawm kev tsim hluav taws xob off-grid photovoltaic fais fab system: nyob rau hauv qhov chaw ntawm kev ua tau raws li qhov xav tau ntawm lub hwj chim ntawm lub load, siv qhov tsawg tshaj plaws photovoltaic modules thiab roj teeb muaj peev xwm kom txuag tau tus nqi nkag.
1. Tsim qauv ntawm photovoltaic modules: lub zog siab tshaj plaws ntawm lub hnub ci cell modules=(load fais fab (W) * load fais fab teev ib hnub twg * cov coefficient ntau ntxiv thaum lub sij hawm los nag) / (system efficiency * lub zos nruab nrab nruab nrab hnub ci hnub ci teev)
2. Tsim ntawm PV maub los. Kev tswj tam sim no ntawm photovoltaic maub los=lub zog siab tshaj plaws ntawm lub hnub ci cell module / qhov ntsuas hluav taws xob ntawm lub roj teeb pob. Nws yuav tsum tau muab sau tseg tias nyob rau hauv high-altitude cheeb tsam, lub photovoltaic maub los yuav tsum tau kom loj ib tug tej yam margin thiab siv nws nrog derating. Nco tseg: Cov npoo yog hais txog qhov sib txawv ntawm qhov tsim qhov siab tshaj plaws txwv thiab kev ua haujlwm ib txwm txwv ntawm qee qhov ntsuas ntawm cov khoom siv.
3. Tsim ntawm off-grid inverter. Lub peev xwm ntawm lub inverter=(lub hwj chim ntawm lub load (W) * lub margin yam yuav tsum tau los ntawm lub inverter) / lub hwj chim yam ntawm lub inverter
4. Tsim cov roj teeb txhuas-acid. Lub peev xwm ntawm lub roj teeb pob=(lub zog ntawm lub load (W) * tus naj npawb ntawm cov xuab moos ntawm kev siv hluav taws xob ib hnub * tus naj npawb ntawm cov hnub los nag sib law liag) / (cov ntsuas hluav taws xob ntawm lub roj teeb pob * qhov tso tawm coefficient ntawm lub roj teeb * lub efficiency ntawm lub inverter)
