Lub inverter yog lub hlwb thiab lub plawv ntawm lub zog tsim hluav taws xob photovoltaic. Hauv cov txheej txheem ntawm lub zog tsim hluav taws xob photovoltaic hnub ci, lub zog tsim los ntawm photovoltaic array yog DC zog. Txawm li cas los xij, ntau lub nra hnyav xav tau AC zog, thiab lub zog DC lub cev muaj kev txwv loj thiab tsis yooj yim hloov lub zog hluav taws xob. , qhov ntau ntawm daim ntawv thov thauj khoom kuj txwv, tshwj tsis yog cov khoom siv hluav taws xob tshwj xeeb, inverters yuav tsum tau hloov DC zog mus rau AC zog. Lub photovoltaic inverter yog lub plawv ntawm lub zog tsim hluav taws xob photovoltaic hnub ci, uas hloov cov tam sim no ncaj qha los ntawm cov modules photovoltaic mus rau hauv alternating tam sim no, thiab xa mus rau lub nra hnyav hauv zos lossis grid, thiab yog lub cuab yeej hluav taws xob hluav taws xob nrog cov haujlwm tiv thaiv cuam tshuam.
Lub hnub ci inverter feem ntau yog tsim los ntawm cov khoom siv fais fab, cov laug cam tswj hwm, cov khoom siv hluav taws xob, cov lim dej, cov reactors, transformers, contactors thiab cov txee. Cov txheej txheem tsim khoom suav nrog kev ua tiav cov khoom siv hluav taws xob, kev sib dhos ua tiav, kev sim thiab kev ntim khoom tiav. Nws txoj kev loj hlob nyob ntawm kev loj hlob ntawm cov thev naus laus zis hluav taws xob, cov thev naus laus zis semiconductor thiab cov thev naus laus zis tswj niaj hnub.
Rau cov inverters hnub ci, kev txhim kho kev hloov pauv ntawm kev muab hluav taws xob yog ib qho kev kawm tas mus li, tab sis thaum qhov ua tau zoo ntawm lub kaw lus tau nce siab thiab siab dua, yuav luag ze li ntawm 100%, kev txhim kho kev ua tau zoo ntxiv yuav nrog rau kev ua tau zoo tsawg. Yog li ntawd, yuav ua li cas kom muaj kev ua tau zoo siab, tab sis kuj tseem yuav tswj hwm kev sib tw nqi zoo yuav yog ib qho kev kawm tseem ceeb tam sim no.
Piv nrog rau kev siv zog los txhim kho qhov ua tau zoo ntawm lub inverter, yuav ua li cas txhim kho qhov ua tau zoo ntawm tag nrho lub inverter system maj mam dhau los ua lwm qhov teeb meem tseem ceeb rau lub hnub ci zog. Hauv lub hnub ci array, thaum thaj chaw 2% -3% ntawm qhov ntxoov ntxoo tshwm sim, rau lub inverter siv MPPT function, lub zog tso zis ntawm lub system thaum lub sijhawm no yuav poob txog li 20% thaum lub zog tso zis tsis zoo. Yuav kom hloov kho tau zoo dua rau qhov xwm txheej zoo li no, nws yog ib txoj hauv kev zoo heev los siv ib-rau-ib MPPT lossis ntau lub luag haujlwm tswj hwm MPPT rau ib lossis ib nrab hnub ci modules.
Vim tias lub tshuab inverter nyob rau hauv lub xeev ntawm kev ua haujlwm txuas nrog grid, qhov xau ntawm lub kaw lus mus rau hauv av yuav ua rau muaj teeb meem kev nyab xeeb loj; ntxiv rau, txhawm rau txhim kho qhov ua tau zoo ntawm lub kaw lus, feem ntau ntawm cov hnub ci arrays yuav txuas nrog ua ke los tsim cov hluav taws xob DC siab; Vim muaj qhov tshwm sim ntawm cov xwm txheej tsis zoo ntawm cov electrodes, nws yooj yim los tsim DC arc. Vim yog lub zog DC siab, nws nyuaj heev rau tua lub arc, thiab nws yooj yim heev los ua hluav taws. Nrog rau kev siv dav dav ntawm cov hnub ci inverter systems, qhov teeb meem ntawm kev ruaj ntseg ntawm lub kaw lus kuj tseem yuav yog ib feem tseem ceeb ntawm cov thev naus laus zis inverter.
