Ua lub tsev hluav taws xob cia cov roj teeb xav tau cov hloov tshwj xeeb?
Nyob rau hauv kev txhim kho kev txhim kho kev txhim kho kev txhim kho thaj chaw hauv thaj chaw Shanghai Cov engineers nws thiaj li muab cov teeb meem ntawm 5kva uas qhia tau qhov teeb meem tseem ceeb ntawm kev cia siab hauv tsev
I. Qhov kev teeb meem hluav taws xob teeb meem ntawm lub zog cia lub tshuab
Lub zog hluav taws xob cia khoom hluav taws xob feem ntau tso zis 48V DC, thaum cov khoom siv hauv tsev neeg yuav tsum tau 220V AC. Cov kev daws teeb meem ib txwm ntseeg rau lub zog hluav taws xob, tab sis thaum cov roj teeb pob txuas nrog kev ua haujlwm plummet los ntawm 96% mus rau 88%. Tsis zoo tseem, qhov voltage nyob rau thaum xaus ntawm cov txhuas kua roj teeb tuaj yeem poob rau hauv lub inverter cov zis ntau dua 15%, ua rau qhov tsis ua tiav ntawm cov cuab yeej ua kom zoo.
Peb-theem tsis txaus yog lwm qhov kev txaus ntshai zais. Cov ntaub ntawv ntsuas qhia tau tias thaum cua txias (ib ntu 3kW) thiab lub zog sib npaug ntawm cov sijhawm (peb-theem sib npaug ntawm cov khoom (peb-theem Nyob rau lub sijhawm no, peb-theem kev noj muaj nuj nqi ntawm cov hloov tshwj xeeb tuaj yeem ua kom tsis muaj kev tsis sib haum xeeb mus rau hauv 5%.
II.Qhov plaub qhov tseem ceeb ntawm cov hloov pauv tshwj xeeb
Voltage Kev yoog raws: Amorphous Alloy Transformer tuaj yeem ruaj khov rau 220V ± 3%, nrog rau lub sijhawm ntsuas hluav taws xob kev cai thev naus laus zis, lub sijhawm teb tsuas yog 20ms.
Kev rho tawm hluav taws xob: Ob chav rwb thaiv tsev tsim blocks dc tivthaiv backfeeding thiab txo cov kab ke ua phem rau cov kab sib xyaw kom tsawg dua {{0%}. 5%.
Zog kev txhim kho kev ua kom muaj zog, tau txais cov phiaj xwm kev pab cuam hluav taws xob, kev sib tw poob thaum tsaus ntuj yog txo qis dua 200 rMB hauv hluav taws xob nqi ib xyoos.
Kev nthuav dav yooj yim: 30% cov peev txheej yog tshwj tseg los txhawb nqa PV lub peev xwm nce ntxiv. Tom qab retrofitting, pv nkag tau muaj peev xwm ntawm ib tsev neeg nyob hauv Beijing tau nce los ntawm 5kW txog 8kW.
III. Cov ciaj ciam ntawm lwm cov kev daws teeb meem
Rau cov tshuab me me hauv qab no 10kh, cov zaus siv hluav taws xob uas muaj zog sib cais tuaj yeem hloov pauv hloov pauv. Nws llc resonant topology ua rau muaj kev ua tau zoo ntawm 97%, tab sis tus nqi nce qib li 40%. Thiab thaum lub zog tso rau lub zog ntau dua 15kw, tag nrho lub neej lub neej ntawm cov hloov pauv hloov tau yog qhov ua tau 25% qis dua.
Xaiv mis:
Transformer Muaj Peev Xwm (Kva)=Kev Siv Zog Tuaj Zog (KW) × 1.25
Piv txwv li: 10KW system yuav tsum muaj 12,5kva transformer, nyiam sab nraum zoov hom nrog IP65 kev tiv thaiv.
IV.Qhov Yav Tom Ntej Txuj Ci: Qhov nce ntawm cov hloov pauv tau ntse
Ib lub lag luam German tau tsim tawm cov kev hloov pauv digital, ua-rau hauv dav-bandwidth semiconductor cov cuab yeej siv tiag tiag. Thaum xaiv qhov chaw hluav taws xob hluav taws xob yog kuaj pom, 5% cov nyiaj them hluav taws xob tuaj yeem ua tiav nyob rau hauv 0. 1 vib nas this. Nws qhov kev sib txuas ua ke algorithm nrog lub zog cia system txuas ntxiv txhim kho peak thiab Valley Sedinage rov los ntawm 18%.
Lub National Zog Cov Thawj Tswj Hwm's 2025 txoj kev npaj qhia tias cov hloov pauv ntse yuav tsav tus nqi hauv tsev khaws cia los ntawm 30%. Thaum peb txhim kho photovoltaic panels ntawm lub ru tsev, hloov pauv, yog hloov pauv, yog tseem yuav muab lub zog zoo rau txhua tus ntawm cov hluav taws xob.
