Kev tsom xam tus nqi-zoo ntawm hnub ci inverters: yuav ua li cas xaiv qhov zoo
Raws li lub ntiaj teb kev thov rau lub zog huv si tseem nce ntxiv, lub hnub ci zog, raws li lub zog tauj dua tshiab thiab tsis muaj kuab lom, tau dhau los siv ntau dua. Raws li cov cuab yeej tseem ceeb hauv lub hnub ci hluav taws xob tsim hluav taws xob, qhov kev ua tau zoo thiab kev ua tau zoo ntawm lub hnub ci inverter ncaj qha cuam tshuam rau kev ua tau zoo thiab rov qab los ntawm kev nqis peev ntawm tag nrho cov system. Rau cov neeg lag luam wholesale thoob ntiaj teb, yuav ua li cas thiaj li xaiv tau zoo ntawm ntau lub npe thiab cov qauv ntawmhnub ci invertertau dhau los ua qhov tseem ceeb ntawm lawv txoj kev mloog. Tsab ntawv xov xwm no yuav tshawb xyuas qhov txiaj ntsig zoo ntawm hnub ci inverters los pab cov neeg yuav khoom txiav txim siab zoo dua.

1. Hom thiab yam ntxwv ntawm hnub ci inverter
Hnub ci inverters feem ntau muab faib ua hom hauv qab no:

1. Centralized inverters
Centralized inverters yog haum rau loj-scale hauv av photovoltaic fais fab chaw nres tsheb, uas yog yus muaj los ntawm siab zog, high efficiency thiab kuj tsis tshua muaj nqi. Nws centrally inverts cov tam sim no ncaj qha generated los ntawm ntau photovoltaic modules, thiab txuas lawv mus rau lub high-voltage kis tau tus mob system tom qab converging los ntawm lub thawv combiner. Qhov kom zoo dua ntawm lub inverter no yog tias nws tuaj yeem siv tag nrho cov khoom siv hluav taws xob qhib thiab ruaj khov hnub ci kom ua tiav cov khoom siv hluav taws xob loj, tab sis nws qhov tsis zoo yog tias nws muaj qhov zoo sib xws rau photovoltaic modules. Thaum qee qhov modules tsis ua haujlwm lossis raug thaiv, nws yuav cuam tshuam rau lub zog tsim hluav taws xob ntawm tag nrho cov system.
2. Txoj hlua inverter
Cov hlua inverter faib cov photovoltaic modules rau hauv ob peb txoj hlua, txhua qhov txuas nrog lub inverter. Nws muaj qhov zoo ntawm lub zog tsim hluav taws xob, kev ntseeg siab, kev nyab xeeb siab, kev txhim kho yooj yim thiab kev txij nkawm, thiab lwm yam thaum lub module thaiv los ntawm cov duab ntxoov ntxoo los yog ua tsis tiav, vim muaj ntau lub channel MPPT (qhov siab tshaj plaws ntawm lub hwj chim taw tes), nws tsuas yog cuam tshuam rau lub zog tsim ntawm ob peb txoj hlua sib txuas, uas tuaj yeem txo qhov kev puas tsuaj, txo cov array mismatch poob, thiab ua tiav ntau dua. Tsis tas li ntawd, ib leeg-tshuab lub zog ntawm txoj hlua inverter yog maj mam nce, maj mam txo tus nqi sib txawv nrog lub hauv paus inverter, thiab ua kom nrawm nkag mus rau qhov chaw nres tsheb fais fab loj loj.
3. Micro inverter
Lub micro inverter ua qhov sib cais lub zog siab tshaj plaws nrhiav rau txhua qhov photovoltaic module, thiab tom qab ntawd txuas mus rau AC daim phiaj tom qab inversion. Lub peev xwm ib leeg yog feem ntau qis dua 1KW. Nws qhov zoo dua yog tias nws tuaj yeem txo qis kev nyab xeeb thiab tsim nyog rau cov haujlwm me me, xws li cov tsev nyob thiab cov tsev lag luam me. Txawm li cas los xij, tus nqi ntawm micro inverter yog qhov siab, thiab nws nyuaj rau kev tswj xyuas tom qab ua tsis tiav.
4. Distributed inverter
Lub inverter faib tau paub txog ntau lub channel MPPT optimization muaj nuj nqi los ntawm kev txhim kho ntau yam MPPT tswj optimizers, thiab txais yuav centralized inverter rau inversion tom qab convergence. Nws ua ke qhov zoo ntawm "centralized inversion" ntawm lub hauv paus loj photovoltaic inverters thiab "muab MPPT taug qab" ntawm txoj hlua photovoltaic inverters, ua tiav cov nqi qis thiab kev ntseeg siab ntawm centralized inverters thiab lub zog tsim hluav taws xob ntawm cov hlua inverters. Txawm li cas los xij, muaj kev paub txog kev tsim hluav taws xob me me hauv kev faib tawm inverters, thiab kev nyab xeeb thiab kev ruaj ntseg xav tau kev txheeb xyuas ntxiv.

2. Cov yam ntxwv cuam tshuam rau cov nqi kev ua haujlwm ntawm hnub ci inverters

1. conversion efficiency
Conversion efficiency yog ib qho tseem ceeb ntsuas ntsuas qhov kev ua tau zoo ntawm hnub ci inverters, uas yog ncaj qha ntsig txog cov nqi ntawm lub zog tsim.
