Muaj pes tsawg hnub ci vaj huam sib luag nyob hauv ib qho array?

Lub photovoltaic array yog kev sib txuas ntawm ntau lub photovoltaic modules thiab ntau lub cell photovoltaic. Lub photovoltaic array yog qhov loj tshaj plaws photovoltaic zog tsim system.

Lub photovoltaic array yog ib qho khoom siv uas siv lub photoelectric hloov dua siab tshiab los hloov lub hnub ci zog rau hauv DC lub zog. Nws yog tsim los ntawm ntau qhov sib cuam tshuam photovoltaic modules.

Lub photovoltaic module yog tsim los ntawm ntau lub hnub ci, uas tuaj yeem hloov lub hnub ci zog rau hauv DC lub zog, thaum lub photovoltaic array sib txuas ntau lub photovoltaic modules ua ke thiab txuas lawv los ua ib qho tag nrho los ua kom lub zog tso zis ntau ntxiv.

Cov muaj pes tsawg leeg ntawm cov photovoltaic array muaj xws li: photovoltaic modules, brackets, cable AC / DC converters, thiab lwm yam. Nyob rau hauv cov ntaub ntawv siv, ntau photovoltaic arrays txuas nyob rau hauv parallel los yog nyob rau hauv series los tsim ib tug ntau yam ntawm lub hnub ci zog tsim systems, xws li tsev neeg photovoltaic zog. tiam tshuab, lag luam photovoltaic zog tsim tshuab, loj photovoltaic fais fab chaw nres tsheb, thiab lwm yam.

Qhov zoo ntawm photovoltaic arrays yog tias lawv tuaj yeem hloov cov khoom siv hluav taws xob hnub ci ncaj qha rau hauv hluav taws xob hluav taws xob, tsis muaj kuab paug, tsis muaj suab nrov, muaj lub neej ntev, thiab yooj yim los tswj. Nyob rau tib lub sijhawm, lawv tuaj yeem tau txais thiab ua tau zoo taug qab lub hnub kom tau txais cov khoom siv hluav taws xob ntau tshaj plaws, nrog cov txiaj ntsig zoo ntawm kev lag luam thiab ib puag ncig.

Hauv kev siv tiag tiag, tus naj npawb ntawm PV arrays nyob rau hauv series thiab parallel yuav sib txawv raws li qhov xav tau ntawm cov ntawv thov tshwj xeeb scenarios. Feem ntau, tus naj npawb ntawm PV arrays nyob rau hauv series thiab parallel nyob ntawm cov hauv qab no:

1.Input voltage thiab tam sim no yuav tsum tau:

Yog tias yuav tsum muaj qhov hluav taws xob ntau dua thiab tam sim no, ntau lub PV modules yuav tsum tau txuas nrog hauv cov koob. Ntawm qhov tsis sib xws, yog tias qhov hluav taws xob qis dua thiab tam sim no xav tau, ntau lub PV modules yuav tsum tau txuas nrog tib lub sijhawm.

2. Tsim cov yam ntxwv ntawm lub hnub ci vaj huam sib luag:

Tus naj npawb ntawm cov kev sib txuas thiab cov kab sib txuas yuav sib txawv nyob ntawm tus qauv tsim thiab xaiv cov photovoltaic modules. Piv txwv li, yog hais tias lub hnub ci vaj huam sib luag muaj zog cua kub dissipation thiab lub teeb haum lub peev xwm, yuav tsum tau ib tug me me ntawm series kev sib txuas, thaum lub hnub ci vaj huam sib luag nrog ib tug dav ntawm qhov chaw yuav tsum tau ib tug loj tus naj npawb ntawm kev sib txuas.

3. Environmental factor:

Tus naj npawb ntawm cov koob thiab cov kev sib txuas sib txuas siv kuj tseem yuav sib txawv hauv qhov sib txawv ntawm daim ntawv thov. Piv txwv li, nyob rau hauv qhov chaw siab tshaj los yog kub ib puag ncig, kev sib txuas ntau dua yuav tsum tau ua kom muaj kev ruaj ntseg ntawm qhov poob qis, thaum nyob hauv ib puag ncig nrog cov av noo siab, kev sib txuas ntau dua yuav tsum tau txhim kho qhov ruaj khov ntawm qhov tam sim no.

Nyob rau hauv luv luv, nyob rau hauv lub tswv yim daim ntawv thov, tus naj npawb ntawm series thiab parallel kev twb kev txuas yuav tsum tau comprehensively txiav txim siab thiab xaiv raws li cov kev xav tau ntawm cov tshwj xeeb daim ntawv thov scenario, ua ke nrog cov tsis xws luag thiab zoo, kom tau raws li lub hwj chim mov thiab system stability thiab kev ua tau zoo.

Kev suav ntawm PV array sib nrug feem ntau yuav tsum xav txog cov hauv qab no:

1. Qhov loj thiab kev teeb tsa ntawm lub hnub ci vaj huam sib luag

Qhov loj thiab kev npaj ntawm lub hnub ci vaj huam sib luag yuav cuam tshuam ncaj qha rau cov qauv thiab kev teeb tsa ntawm cov array. Piv txwv li, ntawm tib lub kaum sab xis dispersion, lub vaj huam sib luag loj dua, qhov sib nrug me me ntawm cov arrays tuaj yeem ua tau.

2. Ntsig qhov sib nrug

Array spacing xam feem ntau yog siv rau hauv tus account yam xws li tiv thaiv kev sib nrig sib shading thiab lub zog poob. Thaum arrays tau teem, qhov siab ntawm lub hnub ci vaj huam sib luag yuav tsum tsis tshua muaj los tiv thaiv kev sib nrig sib shading. Txawm li cas los xij, qhov tsawg kawg nkaus qhov siab ntawm lub hnub ci vaj huam sib luag tseem ua kom ntseeg tau tias cov txheej hauv qab ntawm cov vaj huam sib luag tuaj yeem ua kom cua nkag tau zoo yam tsis muaj kev cuam tshuam los ntawm cov daus tsub zuj zuj thiab kev siv tau ntawm kev tu neeg hlau.

3. Kab rov tav sib nrug

Kab rov tav qhov sib nrug ntawm cov hnub ci vaj huam sib luag yuav tsum tau txiav txim siab. Qhov kev ncua deb no feem ntau yuav tsum tau coj mus rau hauv tus account qhov seem cua sov thiab qhov cua ntawm lub hnub ci vaj huam sib luag, nrog rau lub hnub ci loj tshaj plaws, cov xov hlau thiab lwm yam khoom siv. Qhov no ua kom ntseeg tau tias array cov channel tuaj yeem ua raws li cov ntsiab lus no.

4. Cov teeb meem hauv av thiab cov dej ntws

Qhov siab thiab tso dej ntawm lub hnub ci cell system tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub cev. Yog tias hauv av tsis sib luag thiab tsis muab cov kua dej zoo, nws yuav tsum ua kom cov av tiaj tus thaum xav tias cov array yog ze rau hauv av dua li cov hnub ci vaj huam sib luag, vim qhov kev ncua deb ntawm av thiab cov panels yuav tsum me me. . Nyob rau tib lub sijhawm, yuav tsum muaj cov kua dej ntshiab hauv qab cov array.

Kev suav qhov sib nrug ntawm photovoltaic arrays yog ib txoj haujlwm nyuaj uas yuav tsum tau xav txog ntau yam. Ua ntej tsim thiab txhim kho lub photovoltaic array, nws yog qhov zoo tshaj plaws los sab laj ib tus kws tshaj lij hnub ci engineer lossis lub tuam txhab kev sab laj kom ntseeg tau qhov kev ua tau zoo thiab kev nyab xeeb ntawm lub cev.
