Dab tsi yog Lub Luag Haujlwm thiab Kev Ua Haujlwm ntawm Photovoltaic Inverters?

ltaic array system thiab tuaj yeem siv nrog cov cuab yeej siv hluav taws xob AC. Raws li ib tug hloov dua siab tshiab ntaus ntawv rau photovoltaic fais fab chaw nres tsheb, lub photovoltaic inverter plays lub luag hauj lwm tseem ceeb nyob rau hauv tag nrho cov fais fab chaw nres tsheb.

Lub luag haujlwm ntawm photovoltaic inverter

Lub photovoltaic inverter converts DC lub zog tsim los ntawm photovoltaic module rau hauv sine yoj tam sim no, txuas mus rau lub load los yog integrates rau hauv daim phiaj fais fab. Nws yog cov cuab yeej tseem ceeb hauv qhov chaw nres tsheb fais fab photovoltaic. Nws tuaj yeem hloov pauv qhov sib txawv ntawm DC voltage tsim los ntawm photovoltaic (PV) hnub ci vaj huam sib luag rau hauv AC fais fab (AC) inverter ntawm lub ntsiab zaus, uas tuaj yeem muab rov qab rau kev lag luam hluav taws xob xa hluav taws xob lossis siv rau cov phiaj xwm tawm hluav taws xob.

Kev ua haujlwm ntawm photovoltaic inverter

Lub photovoltaic inverter tsis tsuas muaj DC-AC hloov dua siab tshiab muaj nuj nqi, tab sis kuj muaj active kev khiav hauj lwm thiab kaw lub zog, siab tshaj plaws lub hwj chim mus txog qhovtwg MPPT zog, kob nyhuv nrhiav thiab tswj functions, daim phiaj nrhiav kom tau thiab daim phiaj kev twb kev txuas functions, thiab xoom (tsawg) voltage caij- los ntawm kev ua haujlwm.

1. Kev ua haujlwm nquag thiab kaw haujlwm

Tom qab hnub sawv ntxov, qhov kev siv ntawm lub hnub ci hluav taws xob maj mam nce, thiab cov zis ntawm lub hnub ci kuj nce raws li. Thaum cov zis hluav taws xob xav tau los ntawm kev ua haujlwm inverter mus txog, lub inverter yuav cia li pib ua haujlwm. Tom qab nkag mus rau hauv lub lag luam, lub inverter yuav saib xyuas cov zis ntawm lub hnub ci cell module txhua lub sijhawm. Ntev npaum li qhov tso zis hluav taws xob ntawm lub hnub ci cell module ntau dua li qhov tso zis hluav taws xob xav tau los ntawm kev ua haujlwm inverter, lub inverter yuav ua haujlwm ntxiv; txog hnub poob, lub inverter tuaj yeem ua haujlwm txawm tias hnub los nag. Thaum cov zis ntawm lub hnub ci cell module txo thiab cov zis inverter yog ze rau 0, lub inverter yuav nkag mus rau lub xeev standby.

2. Lub zog siab tshaj plaws taug qab MPPT muaj nuj nqi

Thaum lub hnub ci siv zog thiab ambient kub hloov, lub zog nkag ntawm photovoltaic module qhia cov kev hloov pauv uas tsis yog-linear. Lub photovoltaic module tsis yog qhov chaw qhov hluav taws xob tas li lossis qhov chaw tam sim no tsis tu ncua. Nws lub hwj chim hloov nrog cov zis voltage thiab tsis muaj dab tsi ua rau lub load. Nws cov zis tam sim no yog kab kab rov tav thaum pib thaum qhov hluav taws xob nce. Thaum nws ncav cuag ib lub hwj chim, nws txo qis raws li qhov voltage nce. Thaum nws mus txog qhov qhib qhov hluav taws xob ntawm lub module, tam sim no poob rau xoom.

3. Kev txheeb xyuas thiab tswj kev ua haujlwm ntawm cov nyhuv ntawm cov kob

Thaum lub sij hawm tsim hluav taws xob ib txwm muaj, lub tshuab hluav taws xob photovoltaic txuas nrog lub zog hluav taws xob txuas nrog rau daim phiaj hluav taws xob thiab xa cov hluav taws xob zoo mus rau daim phiaj hluav taws xob. Txawm li cas los xij, thaum daim phiaj hluav taws xob poob qis, lub tshuab hluav taws xob photovoltaic txuas nrog lub zog hluav taws xob tuaj yeem ua haujlwm txuas ntxiv thiab nyob rau hauv ib qho kev lag luam ywj pheej nrog cov khoom hauv zos. Qhov tshwm sim no hu ua cov nyhuv ntawm cov kob. Thaum lub inverter muaj cov nyhuv ntawm cov kob, nws yuav ua rau muaj kev nyab xeeb zoo rau tus kheej kev nyab xeeb, kev ua haujlwm ntawm lub zog hluav taws xob, thiab lub inverter nws tus kheej. Yog li ntawd, tus txheej txheem nkag mus rau inverter tau teev tseg tias photovoltaic daim phiaj-txuas inverter yuav tsum muaj kev tshawb nrhiav thiab tswj kev ua haujlwm ntawm cov nyhuv ntawm cov kob.

4. Kev kuaj xyuas daim phiaj hluav taws xob thiab daim phiaj sib txuas ua haujlwm

Ua ntej kev sib txuas hluav taws xob tsim hluav taws xob, daim phiaj-txuas inverter yuav tsum tau siv lub zog los ntawm daim phiaj, kuaj xyuas qhov voltage, zaus, theem sib lawv liag thiab lwm yam tsis zoo ntawm daim phiaj hluav taws xob, thiab tom qab ntawd kho nws tus kheej lub zog tsim hluav taws xob rau synchronize nrog cov kab sib chaws. . Tsuas yog tom qab ua tiav nws yuav txuas nrog daim phiaj rau kev tsim hluav taws xob.

Copper tube kawg cap rau PV fuse yog cov khoom tseem ceeb tsim tshwj xeeb rau cov tshuab photovoltaic thiab yog siv dav hauv cov khoom siv xws li hnub ci vaj huam sib luag thiab photovoltaic inverters. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv cov circuits hauv qhov system photovoltaic los ntawm kev puas tsuaj los ntawm overload lossis luv luv Circuit Court, yog li ua kom muaj kev nyab xeeb ntawm tag nrho cov system.
