Cov tswv yim tsim los txhim kho lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag
Lub Rau Hli feem ntau yog ib lub hlis zoo tshaj plaws ntawm lub xyoo rau kev tsim hluav taws xob. Kev tsim hluav taws xob ruaj khov thiab muaj txiaj ntsig zoo ntawm lub chaw nres tsheb fais fab yog sib cais los ntawm qhov chaw tsim hluav taws xob zoo tsim. Cov chaw tsim hluav taws xob ua kom zoo nkauj suav nrog kev xaiv cov khoom siv, cov khoom siv array tsim, sub-array thaiv kev tsim, Cable layout tsim, thiab lwm yam. Peb qhia ntau yam uas cuam tshuam rau lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag los ntawm kev xav ntawm kev tsim, uas tuaj yeem txhim kho tus tswv lub zog. nyiaj tau los.
1. Siv cov khoom siv tau zoo
High-efficiency Cheebtsam muaj qhov zoo ntawm "ntau zog, qis attenuation, thiab kev ntseeg tau ntau dua". Lub zog siab thiab qis qis qis txhim kho lub zog tsim hluav taws xob thiab kev pabcuam lub neej.
2. optimize tus naj npawb ntawm cov khoom nyob rau hauv series thiab parallel
Tus naj npawb ntawm PV modules hauv series yuav tsum raug xam raws li cov qauv hauv qab no:
Hauv cov qauv: Vdc max - qhov siab tshaj plaws DC input voltage ntawm inverter (V)
Vmppt min-Inverter MPPT voltage yam tsawg kawg nkaus tus nqi (V)
Vmppt max-Inverter MPPT voltage siab tshaj tus nqi (V)
Voc-PV module qhib Circuit Court voltage (V)
Vpm-PV module ua haujlwm voltage (V)
Kv-PV module qhib Circuit Court voltage kub coefficient
K'v-kub coefficient ntawm kev khiav hauj lwm voltage ntawm photovoltaic modules
t'-qhov kub siab tshaj plaws nyob rau hauv kev ua haujlwm ntawm photovoltaic modules (degree)
t - qhov kub tsawg kawg nkaus raws li kev ua haujlwm ntawm photovoltaic modules (degree)
N - Tus naj npawb ntawm PV modules hauv series (N sib npaug)
Qhov siab tshaj plaws ntsuas kub ntawm qhov project yog suav tias yog 45 degree, thiab qhov tsawg kawg nkaus txwv kub yog suav tias yog -15 degree . Ua ke nrog cov tsis sib xws ntawm cov khoom (540Wp Voc=49.5VVmp=41.65V, voltage coefficient -0.27%), qhov txwv siab tshaj ntawm N tau txais: N Tsawg dua lossis sib npaug rau 20.
Hauv qhov project tiag tiag, xav txog kev ua haujlwm siab tau txais nyob rau hauv tag nrho-load MPPT ntawm lub inverter, 16 ~ 18 modules raug xaiv nyob rau hauv series.
Nco tseg: * Qhov kub coefficient yuav tsum raug coj mus rau hauv tus account hauv kev tsim.
* Paub qhov ua tau zoo nkhaus thiab qhov hluav taws xob-zog nkhaus ntawm inverter ntawm qhov sib txawv voltages thiab coj mus rau hauv tus account yog tias muaj xwm txheej tshwj xeeb.
1. Ua tib zoo saib rau kab rov tav thiab ntsug layout tsim ntawm cov khoom
Thaum cov khoom siv me ntsis occluded, kab rov tav thiab ntsug kev teeb tsa cuam tshuam rau cov zis tawm. Cov teeb meem tshwj xeeb xav tau kev suav tshwj xeeb.
2. Optimizing Component String Wiring.
Thaum cov pab pawg ua haujlwm txuas nrog hauv koob, nws yog qhov yuav tsum tau xav txog txoj haujlwm ntawm inverter thiab kev sib txuas ntawm cov hlua ntawm pawg thiab txais yuav ib txoj hauv kev uas txuag tau ntau dua DC cables.
3. Lub peev xwm piv tau tsim
Kev ua kom muaj peev xwm ua tau zoo yog qhov tsim nyog rau kev txhim kho tus nqi siv ntawm cov khoom siv. Cov qauv tsim kom muaj peev xwm sib piv ntawm qhov chaw nres tsheb hluav taws xob faib tsis yog qhov siab tshwj xeeb thiab sim tsis txhob ua rau lub kaw lus muaj qhov tso tseg loj heev ntawm lub teeb.
4. Optimized inverter nkag tsim
Daim ntawv thov ntawm cov khoom siv hluav taws xob siab ua rau qee cov hlua ntawm lub inverter tsis tuaj yeem ua tiav kev sib txuas. Yog tias cov hlua tsim tau muab faib rau ntau qhov MPPT raws li qhov ua tau, nws yuav tsis tsuas yog txo qhov cuam tshuam ntawm cov khoom tsis sib haum, tab sis kuj ua rau lub zog loj tshaj plaws. Yog li ntawd, ntxiv rau kev sib txuas ib txoj hlua tig los yog yooj yim thaiv rau ib qho MPPT hauv kev txiav txim siab ib txwm muaj, vim muaj cov khoom siv hluav taws xob muaj zog, kev sib txuas ntawm txhua qhov inverter MPPT channel yog qhov tseem ceeb thaum txuas cov hlua. Cov hlua ntau dhau tuaj yeem muab ntxiv rau qhov sib lawv liag.
5. Inverter qhov chaw tsim
Nyob rau hauv ib qho kev faib khoom hauv tsev, lub inverter feem ntau yog ntsia rau ntawm phab ntsa, thiab lub inverter raug xaiv nyob ze ntawm kab sib txuas, eaves, thiab lwm qhov chaw uas tsis muaj hnub ci ncaj qha. Nyob rau tib lub sij hawm, lub inverter yuav tsum tau ventilated nyob ib ncig ntawm nws. Nws yog txwv tsis pub muab cov khoom flammable nyob ze ntawm lub inverter. Qhov siab ntawm inverter yog tsim tsim nyog. Tsis tas li ntawd, lub inverter tej zaum yuav nrov, sim kom nws deb ntawm chav pw.
Nyob rau hauv kev lag luam thiab kev lag luam scenarios, lub inverter feem ntau yog ntsia rau ntawm lub ru tsev, thiab xaiv txoj kev anchoring. Qhov kub ntawm lub ru tsev yog siab, thiab lub hnub ci tuaj yeem siv los ntxoov ntxoo lub inverter. Qhov chaw txaus yuav tsum tau tshwj tseg nyob ib ncig ntawm lub inverter kom dissipate cua sov kom ntseeg tau tias qhov kev ncua deb ntawm lub inverter thiab lub inverter, tshwj xeeb tshaj yog nyob rau hauv qab qhov chaw yuav tsum yooj yim rau thaiv.
6. Qhov zoo tshaj plaws kev xaiv cable
Kev xaiv cable feem ntau txiav txim siab txog cov teeb meem ntawm lub peev xwm nqa tam sim no thiab kab poob thiab qhov hluav taws xob poob. Qee qhov kev lag luam thiab kev lag luam xav txog kev siv aluminium cables lossis aluminium alloy cables los txo cov nqi, thiab tib lub sij hawm xav txog qhov zoo ntawm tooj liab-aluminium hloov dua siab tshiab.
Los ntawm kev tsim lub tswv yim, txhawm rau txhim kho lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag, nws yog ib qho tsim nyog yuav tsum tau ua ke ntau yam los ua kom zoo dua. Thaum kawg, qhov kev ua kom zoo ntawm cov nqi hluav taws xob tau ua tiav, es tsis yog qhov kev nrhiav ntawm ib qho kev sib txawv thiab kev txo qis ntawm tag nrho lub zog hluav taws xob tsim los ntawm lwm yam. Nyob rau tib lub sijhawm, raws li cov cuab yeej tseem ceeb ntawm kev hloov pauv kev ua haujlwm ntawm lub tshuab hluav taws xob photovoltaic, lub inverter yuav tsum muaj kev nkag siab tob ntawm lub inverter kom ntseeg tau tias cov nyiaj tau los ntawm qhov system fais fab chaw nres tsheb yog tus nqi siab tshaj.
Peb lub tuam txhab feem ntau yog muab thiab daws cov ntse wireless saib xyuas thiab tswj cov kev daws teeb meem nrog tus nqi qis, kev siv tshuab siab, thiab kev sib txuas lus ruaj khov.
