Thaum peb tham txog lub nroog thaum hmo ntuj, txoj kev teeb pom kev ntawm txoj kev yog ib feem tseem ceeb. Nyob rau hauv xyoo tas los no, lub tswv yim ntawm kev tiv thaiv ib puag ncig ntsuab tau nrov zuj zus ntawm cov pej xeem, thiab lub hnub ci txoj kev teeb pom kev zoo tau nyiam heev. Txhawm rau kom ntseeg tau tias cov teeb pom kev zoo no tuaj yeem txhim kho txoj kev thaum hmo ntuj, peb yuav tsum xav txog ntau yam tseem ceeb xws li wattage ntawm txoj kev teeb, photovoltaic vaj huam sib luag fais fab, roj teeb muaj peev xwm thiab tswj kev ruaj ntseg. Kev tsim thiab teeb tsa ntawm hnub ci txoj kev teeb pom kev zoo yog qhov tseem ceeb. Nws muaj feem cuam tshuam txog seb txoj kev tuaj yeem teeb pom kev zoo thiab mus tas li
Vim li cas peb yuav tsum xyuam xim rau qhov tsis muaj hnub ci txoj kev teeb
Lub hnub ci vaj huam sib luag muaj feem xyuam rau lub peev xwm sau lub zog, uas yog, nws yuav siv sij hawm ntev npaum li cas kom them lub roj teeb nrog lub hnub ci zoo. Lub peev xwm roj teeb LiFePO4 yuav tsum muaj feem cuam tshuam txog seb txoj kev teeb pom kev tuaj yeem txuas ntxiv mus thaum hmo ntuj teeb pom kev zoo. Cov kev txwv no thiab cov khoom ntawm lub hnub ci txoj kev teeb pom kev zoo, yog tias teeb tsa tsis tsim nyog, yuav cuam tshuam rau kev ua haujlwm ntawm lub hnub ci txoj kev teeb pom kev zoo. Piv txwv li, Yog hais tias lub hnub ci vaj huam sib luag & roj teeb muaj peev xwm tsawg dhau, lub teeb txoj kev yuav tsis muaj peev xwm ua tau raws li qhov xav tau ntawm lub zog thaum hmo ntuj, thiab lwm yam. Ntawm qhov tsis sib xws, kev nkag siab tob txog cov kev txwv no tuaj yeem pab tsim kom muaj txiaj ntsig zoo, muaj txiaj ntsig thiab muaj txiaj ntsig zoo hnub ci txoj kev. teeb pom kev zoo uas muab cov teeb pom kev zoo hauv nroog
Xam tag nrho watt-teev ib hnub rau txoj kev lig
Tag nrho watt-teev yog lub zog hluav taws xob uas siv los ntawm hnub ci txoj kev teeb pom kev zoo txhua hnub, uas cuam tshuam ncaj qha rau lub peev xwm ntawm lub roj teeb thiab lub zog xaiv ntawm lub hnub ci vaj huam sib luag. Txhawm rau suav cov kev siv hluav taws xob niaj hnub (tag nrho watt-teev) ntawm lub teeb hauv txoj kev, koj yuav tsum paub ob yam tseem ceeb: lub wattage ntawm lub sijhawm sib txawv thiab cov sijhawm ua haujlwm ntawm txhua lub sijhawm. Cov mis rau kev suav tag nrho watt-teev teev hauv ib hnub yog raws li hauv qab no: Tag nrho watt-teev teev hauv ib hnub = Kev siv hluav taws xob 1 (W) × Tus naj npawb ntawm cov xuab moos ua haujlwm nyob rau lub sijhawm sib txawv. Piv txwv li, piv txwv li, txoj kev teeb pom kev zoo nrog wattage ntawm 100W txoj kev teeb ua haujlwm 12 teev hauv ib hnub, nrog thawj 5 teev ua haujlwm ntawm 100% lub zog thiab 7 teev dhau los ua haujlwm ntawm 50% lub zog, tom qab ntawd suav tag nrho cov watt-teev txhua hnub. raws li nram no: Tag nrho cov watt teev txhua hnub = 100W × 5 teev + 50W × 7 teev = 850 watt teev (Wh). Cov txiaj ntsig suav tuaj yeem siv rau hauv cov ntu hauv qab no los txiav txim siab lub peev xwm roj teeb thiab lub hnub ci vaj huam sib luag lub zog xav tau rau lub hnub ci txoj kev teeb.
Roj teeb ntawm lub hnub ci txoj kev teeb pom kev zoo - muaj peev xwm
Hom roj teeb pom zoo siv rau hauv lub hnub ci photovoltaic yog cov roj teeb sib sib zog nqus. Cov roj teeb lub voj voog sib sib zog nqus yog tsim los rau kev them nyiaj sai tom qab tso tawm mus rau theem qis zog lossis rau kev them nyiaj tas li thiab tawm mus rau ntau xyoo. Lub roj teeb yuav tsum loj txaus los khaws lub zog txaus los khiav LED txoj kev teeb thaum hmo ntuj thiab hnub huab cua. Hnub ci txoj kev teeb pom kev zoo feem ntau siv lithium roj teeb (LiFePO4). Nws muaj lub neej ntev, kev nyab xeeb zoo, thiab siab
Muab xam tag nrho watt teev siv los ntawm lub teeb fixture ib hnub twg. Xam qhov kev hloov dua siab tshiab ntawm qhov system li 95% Xam qhov tob ntawm qhov tso tawm ntawm lub roj teeb. Cov roj teeb lithium raug xam raws li 95% Xam cov hnub ua haujlwm autonomous (uas yog, cov hnub yuav tsum tau ua haujlwm yam tsis muaj photovoltaic panels los tsim hluav taws xob) Yuav tsum muaj roj teeb muaj peev xwm (Wh) = Tag nrho Watt-teev (ib hnub) x Hnub ntawm kev tswj hwm tus kheej / 0.95 / Qhov tob ntawm kev tso tawm ntawm cov roj teeb sib sib zog nqus
E-LITE cov ntaub ntawv kawm txog hnub ci txoj kev teeb pom kev zoo
Tam sim no, peb cov neeg siv khoom tau ua haujlwm rau hnub ci txoj kev teeb pom kev zoo. Cov neeg siv khoom xav tau siv 115W hnub ci txoj kev teeb, uas tsis tas yuav muaj cov sensors thiab siv PWM dimming, tab sis yuav tsum tau teem sijhawm lub sijhawm dimming. Lub sijhawm ua haujlwm tshwj xeeb raws li hauv qab no: thawj lub sijhawm yog 100% thiab txuas ntxiv ua haujlwm rau 5 teev; lub sijhawm thib ob yog 50% thiab txuas ntxiv ua haujlwm rau 7 teev; qhov twg tsuas yog xav tau ib hmo teeb pom kev zoo. Sunshine Sijhawm (Charging.
Txoj kev dav dav yog 8 meters, nrog txoj kev taug kev ntawm 1.5 meters ntawm ob sab. Qhov siab ntawm lub teeb ncej yog 10 meters, qhov ntev ntawm lub cantilever yog 1 meter, thiab qhov deb ntawm lub teeb ncej thiab curb yog 36 meters, uas ua tau raws li qhov yuav tsum tau ntawm M2 teeb pom kev zoo theem. Raws li cov teeb pom kev simulation ntawm E-LITE, nws tau pom tias 115W Omni series yog qhov tsim nyog heev.
Watt-hour ntawm
Raws li qhov project tej yam kev mob, peb xam qhov tseeb zog noj raws li nram no:
Tag nrho txoj kev siv lub teeb = (115W x 5 teev) + (57.5W x 7 teev) = 977.5Wh / hnub
Muaj peev xwm ntawm
Nyob ntawm qhov xwm txheej ntawm qhov project, txij li lub sijhawm ua haujlwm yog rau ib hmo nkaus xwb. Peb mam li txhais no lub zog xav tau
roj teeb muaj peev xwm, coj mus rau hauv tus account qhov voltage ntawm peb lub roj teeb system yog 25.6V
Roj teeb muaj peev xwm = Tag nrho txoj kev siv lub teeb 977.5WH × (0 + 1) / 25.6V / 95% / 95% = 42.3AH
Cov ntsiab lus: Lub roj teeb muaj peev xwm yog: 25.6V / 42A
(lub peev xwm ntawm ib lub roj teeb ntawm tes yog 6AH, yog li 42.3AH yog sib npaug rau 42AH
Wattage ntawm
1, Lub peev xwm tsim hluav taws xob tsawg kawg nkaus ntawm lub roj teeb vaj huam sib luag ib hnub (lub roj teeb yuav raug them tag nrho hauv ib hnub-6 teev)
Luas = 25.6 x 42 AH = 1075.2 WH
2, Yam tsawg kawg nkaus lub zog tsim tam sim no ntawm lub roj teeb vaj huam sib luag
1075.6WH/6H = 179.2W 3, System conversion efficiency 95%
179.2W/95% = 188.63
Raws li cov txiaj ntsig tau, peb tuaj yeem xaiv rau nruab 1pc 36V / 190W (99% kev nyab xeeb them nyiaj tshwj xeeb) hnub ci vaj huam sib luag module kom tau raws li qhov xav tau ntawm lub zog ntawm qhov project.
